Definitions
- This invention relates to that class of shoe machinery known as lasting machines, and especially7 to machines of the type in which the shoe is moved to cause the' work-engaging instrumentalities to operate progressively around the margin of the shoe, as distinguished from machines of the typein which the toe end is lasted by a single operation and the heel end likewise lasted by a single operation.
- the upper is bent over the edge of the insole and is pressed upon the face of the insole before it has been drawn to the intended degree of tightness against the last, and if the coating on the face of the insole is very tenacious. at such times it will materially oppose the creeping of the upper and cause the wiper to slip without fulfilling its upper-tightening function.
- the present invention is shown by the aocompanying drawings as being embodied in a machine comprising a device arranged 'to end the margin of the upper over the edge of the insole, and to press the bent-over portion against the face of the insole.
- This device under conditions to be described later,
- the machine as shown comprises a gripper arranged to act conjointly with the wiper'to grip the upper and to pull it over the face of the insole without touching it to said face until the overdraft has been completed.
- these instrumentalities are actuated in such manner .that the wiper does noty eX- ercise its function of passing the pulled-over portion against the face of the insole until after the upper has been drawn tightly against the last, thus avoiding whatever opposition the aforesaid adhesivecoating on the insole might otherwise offer to the draw. ing of the upper.
- the wiper is, for vthe purposes Vabove stated, under the! stress of a spring'that tends normally to press it against 'theface of the insole, and the gripper thatV co-acts with the wiper is under the stress of a spring that maintains the gripping action.
- the upper is drawn tightly about the last, then, being incapable of following the gripeV ping elements after having given up allr its slack, the pulled-over margin slips from the grip of the grippers, and as soonas. it has' escaped from such grip the wiper respondsL to the stressof itsspring to niove the pulledover portion into contact with the adhesive coatingand to press it against the face of the insole.
- the margin of the upper is thus assured of being pulled over as far as the last will permit before being permitted to contact with the adhesive coating, the subsequent pressing of the pulled-over portion against the face of theinsole being executed so closely upon the escapev of the upper.
- the machine shown is provided with a work-rest ar ranged to sustain the heelpart ot the shoe to the action of the wipers, and is further provided with driven mechanism arranged to move the work-rest toward the wiper, while the latter is overlying the wiped-over portion, to cause supplemental pressure of the wiped-over portion against the coated face of the insole.
- the machine is provided with a detent arranged to hold the gripper away from the wiper to avoid interference with the latter, and to enable the operative to manipulate the shoe without interference trom the gripper. This detent may be moved to release the gripper whenever it is desired to call the y latter into play.
- the aforesaid work-rest which is intended to be used only when operating upon the heel end, is mounted in such manner that it may be moved to and Jfrom its work-sustaining position, and a detent is provided for holding it in said position. rlhis detent also is capable of being moved to release the work-rest so that the latter ⁇ may move to :i remote position where it will not interfere with the manipulation of the shoe while the forepart and shank part are undergoing their part of the lasting operation.
- the work-rest is supported by a carriage that is Lactuated periodically to apply the aforesaid supplemental pressure by which the wiper-over portion of the upper is pressed against the :ta-ce of the insole.
- the work-rest is preferably made in two sections one ot whichwill engage the work, and the other of which will holtA the work-engaging section.
- This sectional construction permits the introduction of a cushioning spring as a backing for the work-engaging section, and permits the work-rest, as a whole, to be shifted relatively to the carriage without alteration of the applied stress of the cushioning spring.
- the workrest may, therefore,
- the wiper is preferably divided into a plurality ol' sections, the latter being movable relatively to each other so as to be capable of exerting their pressure against the tace ot the insole independently of each other, the several sections of the wiper being thus capable olz compensating for variations in the thickness of the pulled-over portion at ditferent points, and being thus adapted to apply their pressure with substantially uniform degree, notwithstanding such varia tions in thickness.
- Both sections of the wiper having only two sections in the example shown, co-act with one gripper, the latter acting conjointly with each of th wiper sections to grip the upper.
- the invention provides a solerest that may be locked in work-sustaining position when the aforesaid worlerest is retracted to its remote position.
- the sole-rest is, however, supported by a fixture relatively to which it is movable, and a spring is arranged to exert Vits stress normally to move the sole-rest to said position, but the solerest will be fixed or yielding according to whether a locking device with which.
- the sole-rest when operating with the aid of the heel part work-rest, the sole-rest may bear upon the tace'ot the insole, but will preferably be unlocked so that it may yield in response to the movement ot the heel part work rest that causes the supplemental pressure of the wiper upon the wiped-over portions.

- a standard is indicated at 15, and the frame of the wiped i the upper over head is indicatedas a whole by numeral 16.
- i shaft 17 is mounted in suitable bearings in the head'and is provided with a Ytight pulley 18 which is driven through a belt 19 by suitable clutch mechanism of wellknown construction (not shown), under the control ol' the operative.
- a brake-rod 2() connected to the clutch-controlling mechanism is arranged to act on pulley 19 to stop the latter when the gripper, hereinafter described, is initsextreme upward and extreme forward position.
- the heelpart work-restv comprises twoA telescoping sections 21 and 22, and is mounted as a unit in a vbracket 23 formed upon a carriage 24. This carriage is mounted lto slide up and down on guides 25 formed upon a part of: the head 16.
- the Astructural details of the work-rest are shown best by Fig.
- the work-engaging portion ot the work-rest includes a stem 26, the latter being arranged to slide in the section 22.
- the latter section is tubular and serves as arholderY for the work-engaging section.
- Bracket 23 is bored to receive section 22., the latter being adapted to slide up and down in theA bracket.
- a flange 22X is formed at the lower end of section 22 to prevent the latter from being withdrawn upwardly from the bracket, and serving to.
- the workrest is in its lower position relatively' to the carriage, but as, shown by Fig. 5 it is. in its upper or potential'work-engaging position relativelyv to the Carriage.
- Section 22 is provided with an external annular groove- 27 to receive a detentY 28 asshown by Figs.” 5 and 7, the detent being'carried ⁇ by the carriage and connecte-d to thelatter by aV pivot member 29.
- a spring hereinafter identifiedl is provided for moving the dete'nt into groove 27 when the lattervis in Vregis-v tration with the detent.
- the holder section ofthe work-rest is ⁇ bored to provide a cavity ⁇ 30 for the reception of stem 26 and a cushioning spring 31. This cavity extends to the top of the holder but .does not extend to the bottom.
- the bottom is, however, bored and tapped for the reception of a screw 32 by which the applied stress of spring 31 may be regulated.
- rllhis spring isv compressed between .the stem 26. and ahead 33 carriedfby the'inner end of' the regulating screw.
- TheA work-engaging sec-tion ot the work-rest is held in the holder section by a screw 341, said screw being fixed in stem 26 and extending radially therefromthrough a slot 35 inthe holder section.
- the purpose of ther slot isV to enable the work-engaging section to yield relatively to the holder section when the carriage is Y moved toward the wiper.
- the rack is actuated periodically by a cam hereinafter dcscribed.
- the connection between the rack and the carriage provides for adjustment of the latter relatively to the rack to take care of lasts of different depth.
- a rod 37 is aflixed to the carriage, and a sleeve 38 is mounted on the rod and adapted to be rotated.
- This sleeve is provided with spur teeth 39 at Vone end, said teeth being in mesh with the teeth of rack 36.
- A. hand-wheel 40 is fixed to the other end of the sleeve, and by turning the hand-wheel the carriage may be adjusted up and down relatively to the rack.
- a stationary disk 41 fixed to rod 37 which disk is partly enclosed within the rim of the hand-wheel, and the confronting faces of the disk and hand-wheel are provided with locking teeth 42 represented by dotted lines in Fig ⁇ 1.
- the sleeve is capable of t moving endwise to connect and disconnect the locking teeth, but such movement does not disconnect the teeth 39 from the teeth of the rack. ⁇ When the hand-wheel 40 is moved to the right the locking teeth are engaged with each other in loclring relation, but when it is moved to the left the teeth are disengaged and the sleeve is unlocked so that it may be rotated to adjust the carriage up and down.
- a link 43 connects the rack 36 with an operatinglever 44 of bell-crank form.
- the fulcrum stud of this lever is indicated at 45.
- a cam roll 46 carried by the lever rides on the face of a cam 47 carried by shaft 17. The effect of the cam is to lift carriage 24, the force of gravity being sufcient to nieve the carriage inthe opposite direction and to keep the cam roll seated on the cam.
- a wiper comprising, in the present instance, two component sections 48, 48.
- These wiper sections are arranged side by side as shown best by Figs. 4 and 6. They are mounted upon a pivot stud 49 that is carried by a reciprocatory bar 50. This bar is moved positively in opposite directions by a cam 51 carried by shaft 17.
- Operating connection from the cam to the bar is formed by lever 52.
- the lower end of the lever is connected to the bar by pivot pin 53, and the fulcrum pin, indicated at 54, is fixed to the lever and has sliding connection with a part of the head 16.
- the head is provided with aslot 55 in which the fulcrum stud moves.
- the vwiper sections bear normally on a rotary anti-friction bushing 56 mounted on a pin 57. This pin is supported by a part of the head 16.
- the wiper sections are movable up and down relatively to and independently of each other so that each of them may take a position according to the thickness of the stock engaged by it without regard to the position taken by the other vfor this purpose a single regulating screw 60 is arranged to regulate both springs.
- screw 60 is screwed into the bar 50 from the upper side, the bar being bored and tapped for that purpose. rihe lower end of the screw bears on a follower 61, and the latter, in turn, bears on the upper end of one of the springs 58.
- a collar 62 formed on the head of the screw bears on a follower 63, and the latter bears on the other spring 58.
- the wiper sections are normally pressed downwardly by the springs 58, they are adapted to be pressed upwardly by the work when the latter is lifted by the slide 24.
- the applied stress of spring 31 of the workrest is greater than the aggregrate stress of springs 58, .and that the wiper sections, rather than the work-rest, yield until the upward movement of the wiper sections is arrested positively by a stop face 64 of bar 50.
- Fig. 18 shows the wiper sections as being pressed against said stop face in consequence of upward movement of the work-rest, ythe wiped-over portion of the upper being subjected to the applied force of spring 31 and being pressed against the face of the insole with a. pressure of corresponding degree.
- Cams 47 and 51 are timed in such relation that the work-rest occupies a lower position whenever the wiper is retracted from the work as shown by Figs. 1, 8 and l11.
- cam 47 acts to lift the work-rest, the shoe being thereby pressed against the wiper kafter the latter has reached a position where it may bring the spring 31 into play to apply supplemental pressure to the bent-over margin of the upper.
- the primary pressure of the wiper is applied by springs 58.
- the members 48, 48 are usable as a wiper, they are usable also as gripping members, their leading ends being formed and arranged to act conjointly with a gripper65.
- rEhe gripping portions of the members 48 are smooth, but that of gripper 65 is preferably roughened and may be so prepared by forming transverse grooves.
- the generalv contour of the gripping face' of gripper 65 is preferably lconcave so that the lower extremity may underlie the wiper sections sufficiently ⁇ to lift the latter against the stress of springs 58.
- the gripper 65 is xed to a bar 66, this bar extending through a guide-sleeve 66X and being adapted to slide up and down therein.
- the upper end of the bar is connected by a pivot pin 68 to an operating lever 67.
- the fulcruln stud of bell-crank lever 44 serves also as the fulcrum stud of lever 67.
- This lever is continuously under the stress of a spring 69 that tends normally to move the gripper' downwardly, upward movement of the gripper being effected by a cam 70 carried by shaft 17.
- the cam acts upon a roll 71, and the latter is carried by a slide 72 arranged to slide up and down in suitable guides formed on the head 16.
- Al rod 73 is fixed to the slide and extends upwardly through a stationary bracket 74.
- Spring 69 which, is helical in form, surrounds rod 73 and is seated upon bracket 74.
- a collar 7 5 fastened to the upper end of the rod bears upon the upper end of the spring, the latter bein compressed between the collar and the l brac (et. The stress of the spring is thus applied to lift the rod and the slide, and cam roll 71 is thereby held in contact wit-h cam 7 O.
- the rear end of' lever 67 is connected to rod 73 by a colla-r 7 6, the collar being loose relatively to the rod and being connected to the lever by trunnions 77.
- the slide 72 is raised by the spring the upper end of the slide abuts against the lower face of collar 7 6 and thereby moves the lever to lower the gripper.
- slide 72 is moved vdown ⁇ wardly collar 76 is depressed by a collar 7 8, the latter being fixed upon rod 73 by a set screw 79.
- the gripper' is moved toward the front by a cam 8O carried by shaft 17.
- This cam acts upon a roll 81 mountedupon a rod 82.
- This rod is arranged to move endwise in suitable bearings in the head 16, and is under the stress of a helical torsion spring 83 that tends tomove it always to the rear, or to the right, as shown by Fig. 1.
- Spring 83 is provided with a regulating device by which its applied stress may be varied.
- the spring is connected to rod 82 by a lever 84, the rod having a projecting Stud 85 against which the lever bea-rs.
- the lever is arranged to oscillate upon a fixed stud 86, and is provided with a lug 87 against which one end of spring 83 bears.
- the other end n of the spring is anchored to a regulating handle 88.
- This handle is arranged to turn upon the stud 86, and is provided with a pawl 89 that co-acts with a fixed ratchet 90.
- the ratchet is shown as being fixed to stud 86.
- the spring may be wound up to any desired degree of stress by moving the handle 88 in a clockwise direction about stud 86, pawl 89 serving to prevent rotation inthe opposite direction.
- Bod 82 carries a forlrQl at its forward end, said forkY straddling sleeve 66X and beingconnected to the sleeve by a pivot pin 92.
- Lever 67 and rod 82 are actuated in such timed relation as to impart a compound movement to theV gripper, the latter being moved to the rear by spring 83 to grip the upper in consequence of spring stress rather than in consequence of any positive action.
- This enables the gripping stress to be regulated' so that the upper may slip from the grippers after being drawn tightly about the last, and in practice itis desirable, for some purposes, torpermit such slipping so. that the stress of the wiper springs 58 may be utilized to press the pulledfover portion of the upperagainst the face of the insole in consequence of the escape of said portion from the gripper.
- the gripper is shown by 'F ig. 1 as having descended on its way to grip the upper against the wiper sections. According to this figure the wiper is retracted to the right as far as it will go, in which position its leading end is behind the work-engaging portion of an edge-rest 93. The gripper proceeds from the position shown by Fig. 1 in a direction indicated by arrow r, such motion being imparted by spring 83. The Inargin of the upper is thereby gripped as shown by Fig. 8. The wiper-bar or carrier is then moved positively toward the left, and at the Same time gripper is lifted by its cam so that its lower end follows a path represented by arrow s.
- a sole-rest 9&1 for determining the planel of the work relatively to the gripping members is aiiixed adjustably to a sliding block 95.
- This block is arranged to slide up and down in suitable guides in a holder 96 which is atlixed to a stationary bracket 97, the latter having a slot 98 through which a clamping screw 99 extends.
- the holder 96 is bored and tapped for the reception of screw 99, and the latter is adapted, when loosened, to move up and down in the slot according to the position taken by the holder. When the Screw is tightened it clamps the holder firmly to the bracket.
- Block is movable up and down relatively to the holder, but it may be locked relatively to the holder by a locking member 100.
- the block is formed with a notch 101 into which and from which the locking member may be moved.
- the locking member is provided with a stem 102 arranged to slide in a suitable bearing formed in holder 96.
- the range of movement of the sole-rest is limited by a pin 103, said pin being arranged in a hole bored through holder 96 and occupying an el0ngated notch 104 formed in the block.
- notch' 101 occupies a position in registration with locking member when the block is as low as retaining pin 103 will permit. The locking member may then be inserted into the locking notch or withdrawn therefrom.
- the sole-rest may be locked when the heelseat work-rest is out of use, but when the latter is in use it is desirable to have the sole-rest unlocked so that the latter can yield to the upward movement oi" the shoe as caused by the heelseat workrest.
- the block 95 is bored for the reception of a helical spring 105, and the latter may be put under compression by a regulating screw 106.
- This screw is held by a fixture 107, the latter being bored and tapped for the reception of said screw and being aiiixed to holder 96.
- a Jfollower 108 is interposed between the screw and the spring. Tt, when using the sole-rest without the heelpart worksupport, the locking member 100 be lett in unlocking position, the spring will serve to keep the sole-rest in the desired position unless excessive upward pressure be exerted on the shoe.
- the sole-rest when using the sole-rest without the heelpart worksupport, the locking member 100 be lett in unlocking position, the spring will serve to keep the sole-rest
- the spring would be suiiicient for the purpose, but the locking member, in use, guards against the possibility of yielding, however great the upward pressure may be.
- the gripper 65 may be held away from the wiper when it is desired to use the latter as a wiper and not as a gripping member.
- lever 67 is provided with a stud 109, and a movable detent is provided for supporting the stud in a raised position.
- the gripper is in its lowest position, and the bottom tace of stud 109 is a considerable distance below the. upper itace ot detent 110.
- the gripper When the gripper is in its highest ⁇ position the bottom face of stud 109 is as high, at least, as the upper' face of the detent, so that the latter may be moved horizontally to a position under the stud.
- Detent 110 is iixed to a rock-shaft 111, and the latter is mounted in suitable ixed bearing members 112, 112, and in movable bearings 113, 113 carried by carriage 24.
- a helical torsion spring 114 is coiled about the rock-shaft, and its upper end is anchored to the adjacent bearing member 112, while its lower end is anchored to a collar 115. This collar is lixed to the rock-shaft by set screw 116.
- Spring 111 tends normally to turn the rock-shaft in a direction that will carry detent 110 to its holding' position under stud 1.09, its normal direction o1 rotation being anti-clockwise in respect to Fig. 7.
- the rock-shaft 111 carries a second detent indicated at 117, the ⁇ function oit which is to hold the gripper in its forward position when the gripper is held in its elevated position by detent 110.
- the fork 91 is provided with a plate 118 behind which a detent 117 is adapted to lie when detent 110 underlies stud 109.
- the oscillatory motion by which detent 110 is moved to release stud 109 is sufiicient to release plate 118.
- the machine is provided with connections from detent 28 of the heelseat work-rest to rock-shaft 111 for the purpose ot releasing the gripper and the heelseat work-rest in unison by one operation.
- Detent 28 is eX- tended to the lett as shown by Figs. 1 and 7 to provide a suitable handle by which it may be moved Jfrom its holding position.
- the other end of' the detent is extended to provide an arm 119, and the latter is connected by a link 120 to an arm 121.
- the hub 122 of the latter arm is arranged to slide on rock-shaft 111, and is located between bearing members 113 so as to be carried up and down with the carriage 21.
- the rock-shaft is provided with an elongated keyway 128, in which a sliding key carried by hub 122 serves to lock the hub to the rockshaft in respect to oscillatory motion without interfering with the up-and-down motion of the hub relatively to the rock-shaft.
- spring 114 is utilized not only to move detents 110 and 117 to holding position, but is utilized also to move detent 28 to holding position, although the latterdetent moves up and down with the carriage 211.
- the clutch-controlling mechanism may be like that shown and described in Letters Patent No. 1,254,917150 stop the shaft 17 when the gripper is in its extreme forward and extreme upward position.
- Detents 110 and 117 are, therefore, free to move. to their holding positions in response to spring 11a in consequence of lifting the heelseat work-rest far enough to place groove 27 in registration with detent 2S.
- the onlyeffort required of the operative for this purpose is that of lifting the heelseat work-rest rela tively to its carriage. lVhen it is desired to discontinue the use of the heelseat workrest and to bring the gripper into play, the only eort required is that of moving detent 2.8.
- Carriage 2a is provided with a spring plunger 124 arranged to engage the under face 125 of the heeseat work-rest, to soften the blow of the latter when it is dropped relatively to the carriage.
- the carriage is bored for the reception of the plunger, and a cushioning spring 126 is arranged in the bottom of the hole so bored.
- the operator will move the detent 28 provided the last rest is in its upper position, which will allow the last rest to drop and move the detents 110, 117 so as to bring the grip per member 65 into operation.

. LASTING IVIACHINE.
Application led December 23, 1918. Serial No. 267,973.
To all wiz-0m t may concern:
Be it known that ORRELL ASHTON, late of Swampscott, in the county of Essex and State of Massachusetts, deceased, invented certain Improvements in Lasting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invention relates to that class of shoe machinery known as lasting machines, and especially7 to machines of the type in which the shoe is moved to cause the' work-engaging instrumentalities to operate progressively around the margin of the shoe, as distinguished from machines of the typein which the toe end is lasted by a single operation and the heel end likewise lasted by a single operation.
ln the manufacture of shoes of some types it is desirable to coat the bottom face of the insole with adhesive substance prior to pulling over the margin of the upper, relying upon the adhesive coating, rather than tacks or other fasteners, to hold the pulled-over margin on the face ofthe insole until the operation by which the outsole is permanently7l secured to the upper. It frequently happens that the adhesive coating of the in- Sole becomes considerably dried before the margin of the upper has been pulled over, with the result that the coating becomes very tenacious. This condition ofthe coating renders the pulling-over operation more difficult, particularly when the upper is lasted by a wiping'action. Incidentally to a wiping action, the upper is bent over the edge of the insole and is pressed upon the face of the insole before it has been drawn to the intended degree of tightness against the last, and if the coating on the face of the insole is very tenacious. at such times it will materially oppose the creeping of the upper and cause the wiper to slip without fulfilling its upper-tightening function.
The present invention is shown by the aocompanying drawings as being embodied in a machine comprising a device arranged 'to end the margin of the upper over the edge of the insole, and to press the bent-over portion against the face of the insole. This device, under conditions to be described later,
has the action of a wiper, and, for conven ience,the latter term is applied to it, although, under conditions to be described first, its action is not that ofa. wiper. The machine as shown comprises a gripper arranged to act conjointly with the wiper'to grip the upper and to pull it over the face of the insole without touching it to said face until the overdraft has been completed. As shown these instrumentalities are actuated in such manner .that the wiper does noty eX- ercise its function of passing the pulled-over portion against the face of the insole until after the upper has been drawn tightly against the last, thus avoiding whatever opposition the aforesaid adhesivecoating on the insole might otherwise offer to the draw. ing of the upper.
The wiper is, for vthe purposes Vabove stated, under the! stress of a spring'that tends normally to press it against 'theface of the insole, and the gripper thatV co-acts with the wiper is under the stress of a spring that maintains the gripping action. Also, incidentally to the pulling-overaction, the upper is drawn tightly about the last, then, being incapable of following the gripeV ping elements after having given up allr its slack, the pulled-over margin slips from the grip of the grippers, and as soonas. it has' escaped from such grip the wiper respondsL to the stressof itsspring to niove the pulledover portion into contact with the adhesive coatingand to press it against the face of the insole. The margin of the upper is thus assured of being pulled over as far as the last will permit before being permitted to contact with the adhesive coating, the subsequent pressing of the pulled-over portion against the face of theinsole being executed so closely upon the escapev of the upper.
from the grip of the gripper that the upper has no appreciable opportunity to lose the tension applied to it by the gripper. This tension is maintained in part by anedge rest against which the shoe may* be held during the operation described, said edge rest being arranged kto press the upper against the edge of the insole.
The pulling-over operation above described is intended Yto be practised on the forepart and shank portion of the shoe-after the heel end has been lasted, and may also be practised on the heel end if desired. Ordinarily, however, it would be suliicient to rely, so far as the heel end is concerned, upon the simpler and more rapid operation of wiping the upper over the insole without gripping it. This is accounted for by the fact that the necessity ior tightening the upper about the last does not apply to the heel end excepting as to tension lengthwise of the shoe, and this tension cannot begin until after one end has been lasted. In order, therefore, to dispense with the gripping action at the heel end, and to expedite and improve the lasting of the latter, I have provided the machine with other means for co-operating with the wiper to last the heel end before lasting` the other parts. By following this order of procedure the machine will have the benefit or the grippers to take up whatever slack may be necessary to tighten the upper after the heel end has been lasted.
For the purpose of promoting the lasting of the heel end as above outlined the machine shown is provided with a work-rest ar ranged to sustain the heelpart ot the shoe to the action of the wipers, and is further provided with driven mechanism arranged to move the work-rest toward the wiper, while the latter is overlying the wiped-over portion, to cause supplemental pressure of the wiped-over portion against the coated face of the insole. Inasmuch as this part ot 'the lasting operation does not require the gripper in the vicinity of the wiper the machine is provided with a detent arranged to hold the gripper away from the wiper to avoid interference with the latter, and to enable the operative to manipulate the shoe without interference trom the gripper. This detent may be moved to release the gripper whenever it is desired to call the y latter into play.
The aforesaid work-rest, which is intended to be used only when operating upon the heel end, is mounted in such manner that it may be moved to and Jfrom its work-sustaining position, and a detent is provided for holding it in said position. rlhis detent also is capable of being moved to release the work-rest so that the latter` may move to :i remote position where it will not interfere with the manipulation of the shoe while the forepart and shank part are undergoing their part of the lasting operation.
The work-rest is supported by a carriage that is Lactuated periodically to apply the aforesaid supplemental pressure by which the wiper-over portion of the upper is pressed against the :ta-ce of the insole. For reasons that willI appear the work-rest is preferably made in two sections one ot whichwill engage the work, and the other of which will holtA the work-engaging section. This sectional construction permits the introduction of a cushioning spring as a backing for the work-engaging section, and permits the work-rest, as a whole, to be shifted relatively to the carriage without alteration of the applied stress of the cushioning spring. The workrest may, therefore,
be moved to and from its operative position without affecting other adjustments.
As another feature of the invention the wiper is preferably divided into a plurality ol' sections, the latter being movable relatively to each other so as to be capable of exerting their pressure against the tace ot the insole independently of each other, the several sections of the wiper being thus capable olz compensating for variations in the thickness of the pulled-over portion at ditferent points, and being thus adapted to apply their pressure with substantially uniform degree, notwithstanding such varia tions in thickness. Both sections of the wiper, the latter having only two sections in the example shown, co-act with one gripper, the latter acting conjointly with each of th wiper sections to grip the upper.
When lasting the iorepart and the shank portion'it is necessary to tilt the shoe to various angles in yorder to do the work thor oughly and eliiciently, but it is nevertheless desirable to have some instrumentality arranged to determine a suitable. working position orc the part being worked. ln view ot this reason the invention provides a solerest that may be locked in work-sustaining position when the aforesaid worlerest is retracted to its remote position. The sole-rest is, however, supported by a fixture relatively to which it is movable, and a spring is arranged to exert Vits stress normally to move the sole-rest to said position, but the solerest will be fixed or yielding according to whether a locking device with which. it ie provided is in or out ol' locking position. ln practice, when operating with the aid of the heel part work-rest, the sole-rest may bear upon the tace'ot the insole, but will preferably be unlocked so that it may yield in response to the movement ot the heel part work rest that causes the supplemental pressure of the wiper upon the wiped-over portions.
It has been stated that the gripperis provided with a dctent to hold it away from the wiper, and that the work-rest is provided with a detent to hold it in work-sustaining position. ln practice these two detents are called upon to function at the same time. and their periods ol nonuse are co-extensive. ln view ot this condition the inven tion provides the said detente with connections by which they may be moved in unison to release the gripper and the work-rest collectively, thus enabling the operative to etect the release of both by one operation instead of having to perform two separate re- (Us U..

They heelpart work-restv comprises twoA telescoping sections 21 and 22, and is mounted as a unit in a vbracket 23 formed upon a carriage 24. This carriage is mounted lto slide up and down on guides 25 formed upon a part of: the head 16. The Astructural details of the work-rest are shown best by Fig. The work-engaging portion ot the work-rest includes a stem 26, the latter being arranged to slide in the section 22. The latter section is tubular and serves as arholderY for the work-engaging section. Bracket 23 is bored to receive section 22., the latter being adapted to slide up and down in theA bracket. A flange 22X is formed at the lower end of section 22 to prevent the latter from being withdrawn upwardly from the bracket, and serving to. limit the upward movement of the tubular section relatively tothe bracket by striking the bottom face of the latter.` As shown by Fig. 1', the workrest is in its lower position relatively' to the carriage, but as, shown by Fig. 5 it is. in its upper or potential'work-engaging position relativelyv to the Carriage. Section 22 is provided with an external annular groove- 27 to receive a detentY 28 asshown by Figs." 5 and 7, the detent being'carried` by the carriage and connecte-d to thelatter by aV pivot member 29. A spring hereinafter identifiedl is provided for moving the dete'nt into groove 27 when the lattervis in Vregis-v tration with the detent.
The holder section ofthe work-rest is` bored to provide a cavity` 30 for the reception of stem 26 and a cushioning spring 31. This cavity extends to the top of the holder but .does not extend to the bottom. The bottom is, however, bored and tapped for the reception of a screw 32 by which the applied stress of spring 31 may be regulated. rllhis spring isv compressed between .the stem 26. and ahead 33 carriedfby the'inner end of' the regulating screw. TheA work-engaging sec-tion ot the work-rest is held in the holder section by a screw 341, said screw being fixed in stem 26 and extending radially therefromthrough a slot 35 inthe holder section. The purpose of ther slot isV to enable the work-engaging section to yield relatively to the holder section when the carriage is Y moved toward the wiper.
The carriage 24 1s moved upr and down by lil a reciproca-tory rack 36. The rack is actuated periodically by a cam hereinafter dcscribed. The connection between the rack and the carriage provides for adjustment of the latter relatively to the rack to take care of lasts of different depth. For this purpose a rod 37 is aflixed to the carriage, and a sleeve 38 is mounted on the rod and adapted to be rotated. This sleeve is provided with spur teeth 39 at Vone end, said teeth being in mesh with the teeth of rack 36. A. hand-wheel 40 is fixed to the other end of the sleeve, and by turning the hand-wheel the carriage may be adjusted up and down relatively to the rack. In order to maintain the adjustment provision is made for locking the sleeve against rotation, such provision comprising a stationary disk 41 fixed to rod 37. This disk is partly enclosed within the rim of the hand-wheel, and the confronting faces of the disk and hand-wheel are provided with locking teeth 42 represented by dotted lines in Fig` 1. Referring now to Fig. 14, the sleeve is capable of t moving endwise to connect and disconnect the locking teeth, but such movement does not disconnect the teeth 39 from the teeth of the rack. `When the hand-wheel 40 is moved to the right the locking teeth are engaged with each other in loclring relation, but when it is moved to the left the teeth are disengaged and the sleeve is unlocked so that it may be rotated to adjust the carriage up and down.
A link 43 connects the rack 36 with an operatinglever 44 of bell-crank form. The fulcrum stud of this lever is indicated at 45. A cam roll 46 carried by the lever rides on the face of a cam 47 carried by shaft 17. The effect of the cam is to lift carriage 24, the force of gravity being sufcient to nieve the carriage inthe opposite direction and to keep the cam roll seated on the cam.
The margin 0, of the upper of an unlasted shoe is bent over the edge of the insole c by a wiper, the latter comprising, in the present instance, two component sections 48, 48. These wiper sections are arranged side by side as shown best by Figs. 4 and 6. They are mounted upon a pivot stud 49 that is carried by a reciprocatory bar 50. This bar is moved positively in opposite directions by a cam 51 carried by shaft 17. Operating connection from the cam to the bar is formed by lever 52. The lower end of the lever is connected to the bar by pivot pin 53, and the fulcrum pin, indicated at 54, is fixed to the lever and has sliding connection with a part of the head 16. For this purpose the head is provided with aslot 55 in which the fulcrum stud moves.
The vwiper sections bear normally on a rotary anti-friction bushing 56 mounted on a pin 57. This pin is supported by a part of the head 16. The wiper sections are movable up and down relatively to and independently of each other so that each of them may take a position according to the thickness of the stock engaged by it without regard to the position taken by the other vfor this purpose a single regulating screw 60 is arranged to regulate both springs. As shown best by Fig. 6, screw 60 is screwed into the bar 50 from the upper side, the bar being bored and tapped for that purpose. rihe lower end of the screw bears on a follower 61, and the latter, in turn, bears on the upper end of one of the springs 58. A collar 62 formed on the head of the screw bears on a follower 63, and the latter bears on the other spring 58. j
Although the wiper sections are normally pressed downwardly by the springs 58, they are adapted to be pressed upwardly by the work when the latter is lifted by the slide 24. in this connection it may be stated that the applied stress of spring 31 of the workrest is greater than the aggregrate stress of springs 58, .and that the wiper sections, rather than the work-rest, yield until the upward movement of the wiper sections is arrested positively by a stop face 64 of bar 50. Fig. 18 shows the wiper sections as being pressed against said stop face in consequence of upward movement of the work-rest, ythe wiped-over portion of the upper being subjected to the applied force of spring 31 and being pressed against the face of the insole with a. pressure of corresponding degree.
Although the members 48, 48 are usable as a wiper, they are usable also as gripping members, their leading ends being formed and arranged to act conjointly with a gripper65. rEhe gripping portions of the members 48 are smooth, but that of gripper 65 is preferably roughened and may be so prepared by forming transverse grooves. The generalv contour of the gripping face' of gripper 65 is preferably lconcave so that the lower extremity may underlie the wiper sections sufficiently `to lift the latter against the stress of springs 58. The gripper 65 is xed to a bar 66, this bar extending through a guide-sleeve 66X and being adapted to slide up and down therein. The upper end of the bar is connected by a pivot pin 68 to an operating lever 67. In the present instance the fulcruln stud of bell-crank lever 44 serves also as the fulcrum stud of lever 67. This lever is continuously under the stress of a spring 69 that tends normally to move the gripper' downwardly, upward movement of the gripper being effected by a cam 70 carried by shaft 17. The cam acts upon a roll 71, and the latter is carried by a slide 72 arranged to slide up and down in suitable guides formed on the head 16. Al rod 73 is fixed to the slide and extends upwardly through a stationary bracket 74. Spring 69, which, is helical in form, surrounds rod 73 and is seated upon bracket 74. A collar 7 5 fastened to the upper end of the rod bears upon the upper end of the spring, the latter bein compressed between the collar and the l brac (et. The stress of the spring is thus applied to lift the rod and the slide, and cam roll 71 is thereby held in contact wit-h cam 7 O. The rear end of' lever 67 is connected to rod 73 by a colla-r 7 6, the collar being loose relatively to the rod and being connected to the lever by trunnions 77. When the slide 72 is raised by the spring the upper end of the slide abuts against the lower face of collar 7 6 and thereby moves the lever to lower the gripper. When slide 72 is moved vdown` wardly collar 76 is depressed by a collar 7 8, the latter being fixed upon rod 73 by a set screw 79.
The gripper' is moved toward the front by a cam 8O carried by shaft 17. This cam acts upon a roll 81 mountedupon a rod 82. This rod is arranged to move endwise in suitable bearings in the head 16, and is under the stress of a helical torsion spring 83 that tends tomove it always to the rear, or to the right, as shown by Fig. 1. Spring 83 is provided with a regulating device by which its applied stress may be varied. For this purpose the spring is connected to rod 82 by a lever 84, the rod having a projecting Stud 85 against which the lever bea-rs. The lever is arranged to oscillate upon a fixed stud 86, and is provided with a lug 87 against which one end of spring 83 bears. The other end n of the spring is anchored to a regulating handle 88. This handle is arranged to turn upon the stud 86, and is provided with a pawl 89 that co-acts with a fixed ratchet 90. The ratchet is shown as being fixed to stud 86. The spring may be wound up to any desired degree of stress by moving the handle 88 in a clockwise direction about stud 86, pawl 89 serving to prevent rotation inthe opposite direction.
The gripper is shown by 'F ig. 1 as having descended on its way to grip the upper against the wiper sections. According to this figure the wiper is retracted to the right as far as it will go, in which position its leading end is behind the work-engaging portion of an edge-rest 93. The gripper proceeds from the position shown by Fig. 1 in a direction indicated by arrow r, such motion being imparted by spring 83. The Inargin of the upper is thereby gripped as shown by Fig. 8. The wiper-bar or carrier is then moved positively toward the left, and at the Same time gripper is lifted by its cam so that its lower end follows a path represented by arrow s. The motion from right to left draws the upper tightly about the last and pulls the margin of the upper over the edge of the insole, while the upwardV motion of the gripper keeps the pulled-over portion of the upper out of contact lwith the face of the insole. `The overf draft of the upper is, therefore, free from all opposition from whatever adhesive subment. lt follows, therefore, that the wiperescapes from the gripper 65 coincidentally with the escape of the upper, and the springs 58 assert themselves immediately to force the wiper sections downwardly and thereby press the pulled-over portion against thek face of the insole. The result of this action is shown by Fig. 10. If the face of the insole is coated with adhesive `substance the latter will hold the pulled-overportion So pressed against it. The gripper, as shown by F ig. 10, is in its initial position, and remains there while the wiper is retracted to its initial position as shown by Fig. 1.
A sole-rest 9&1 for determining the planel of the work relatively to the gripping members is aiiixed adjustably to a sliding block 95. This block is arranged to slide up and down in suitable guides in a holder 96 which is atlixed to a stationary bracket 97, the latter having a slot 98 through which a clamping screw 99 extends. The holder 96 is bored and tapped for the reception of screw 99, and the latter is adapted, when loosened, to move up and down in the slot according to the position taken by the holder. When the Screw is tightened it clamps the holder firmly to the bracket. Block is movable up and down relatively to the holder, but it may be locked relatively to the holder by a locking member 100. The block is formed with a notch 101 into which and from which the locking member may be moved. The locking member is provided with a stem 102 arranged to slide in a suitable bearing formed in holder 96. The range of movement of the sole-rest is limited by a pin 103, said pin being arranged in a hole bored through holder 96 and occupying an el0ngated notch 104 formed in the block. According to the structure shown notch' 101 occupies a position in registration with locking member when the block is as low as retaining pin 103 will permit. The locking member may then be inserted into the locking notch or withdrawn therefrom.
ln practice the sole-rest may be locked when the heelseat work-rest is out of use, but when the latter is in use it is desirable to have the sole-rest unlocked so that the latter can yield to the upward movement oi" the shoe as caused by the heelseat workrest. The block 95 is bored for the reception of a helical spring 105, and the latter may be put under compression by a regulating screw 106. This screw is held by a fixture 107, the latter being bored and tapped for the reception of said screw and being aiiixed to holder 96. A Jfollower 108 is interposed between the screw and the spring. Tt, when using the sole-rest without the heelpart worksupport, the locking member 100 be lett in unlocking position, the spring will serve to keep the sole-rest in the desired position unless excessive upward pressure be exerted on the shoe. Ordinarily,
however, the spring would be suiiicient for the purpose, but the locking member, in use, guards against the possibility of yielding, however great the upward pressure may be.
It has been stated that the gripper 65 may be held away from the wiper when it is desired to use the latter as a wiper and not as a gripping member. For this purpose lever 67 is provided with a stud 109, and a movable detent is provided for supporting the stud in a raised position. As shown by Figs. 1 and 2, the gripper is in its lowest position, and the bottom tace of stud 109 is a considerable distance below the. upper itace ot detent 110. When the gripper is in its highest `position the bottom face of stud 109 is as high, at least, as the upper' face of the detent, so that the latter may be moved horizontally to a position under the stud. Detent 110 is iixed to a rock-shaft 111, and the latter is mounted in suitable ixed bearing members 112, 112, and in movable bearings 113, 113 carried by carriage 24. A helical torsion spring 114 is coiled about the rock-shaft, and its upper end is anchored to the adjacent bearing member 112, while its lower end is anchored to a collar 115. This collar is lixed to the rock-shaft by set screw 116. Spring 111 tends normally to turn the rock-shaft in a direction that will carry detent 110 to its holding' position under stud 1.09, its normal direction o1 rotation being anti-clockwise in respect to Fig. 7.
The rock-shaft 111 carries a second detent indicated at 117, the `function oit which is to hold the gripper in its forward position when the gripper is held in its elevated position by detent 110. For-this purpose the fork 91 is provided with a plate 118 behind which a detent 117 is adapted to lie when detent 110 underlies stud 109. The oscillatory motion by which detent 110 is moved to release stud 109 is sufiicient to release plate 118.
The machine is provided with connections from detent 28 of the heelseat work-rest to rock-shaft 111 for the purpose ot releasing the gripper and the heelseat work-rest in unison by one operation. Detent 28 is eX- tended to the lett as shown by Figs. 1 and 7 to provide a suitable handle by which it may be moved Jfrom its holding position. The other end of' the detent is extended to provide an arm 119, and the latter is connected by a link 120 to an arm 121. The hub 122 of the latter arm is arranged to slide on rock-shaft 111, and is located between bearing members 113 so as to be carried up and down with the carriage 21. The rock-shaft is provided with an elongated keyway 128, in which a sliding key carried by hub 122 serves to lock the hub to the rockshaft in respect to oscillatory motion without interfering with the up-and-down motion of the hub relatively to the rock-shaft. 1n consequence of these connections spring 114 is utilized not only to move detents 110 and 117 to holding position, but is utilized also to move detent 28 to holding position, although the latterdetent moves up and down with the carriage 211.
The clutch-controlling mechanism may be like that shown and described in Letters Patent No. 1,254,917150 stop the shaft 17 when the gripper is in its extreme forward and extreme upward position. Detents 110 and 117 are, therefore, free to move. to their holding positions in response to spring 11a in consequence of lifting the heelseat work-rest far enough to place groove 27 in registration with detent 2S. The onlyeffort required of the operative for this purpose is that of lifting the heelseat work-rest rela tively to its carriage. lVhen it is desired to discontinue the use of the heelseat workrest and to bring the gripper into play, the only eort required is that of moving detent 2.8.
Carriage 2a is provided with a spring plunger 124 arranged to engage the under face 125 of the heeseat work-rest, to soften the blow of the latter when it is dropped relatively to the carriage. The carriage is bored for the reception of the plunger, and a cushioning spring 126 is arranged in the bottom of the hole so bored.
In the operation of the machine, for last ing the toe and sides of the shoe, the operator will move the detent 28 provided the last rest is in its upper position, which will allow the last rest to drop and move the detents 110, 117 so as to bring the grip per member 65 into operation. The shoe is then held up against the bottom rest and laterally against the edge rest 93 with the margin of the upper behind the gripper and in front of the wipers 48. The machine is now started by depression of the treadle to throw in the clutch. The wipers 48 move forwardly, engaging the margin of the upper in a plane somewhat above the shoe bottom and force it against the yieldingly held gripper member 65. At first the wipers 418 are supported by the roll 56 but their movement continues the gripper is lifted by its cam and carries upwardly the ends of the wipers A1S and the gripped portion of the upper. This portion of the upper is first carried under tension upwardly and inwardly of the shoe, as shown in Fig. 9, the margin of the upper being held out of contact with the margin of the innersole. Finally the resistance of the upper overcomes the frictional drag of the upper upon the gripper G5, causing the upper to be left behind as the gripper 65 rises and the -l'rictional hold of the upper on the wipers #i8 will cause them to be freed from the gripper so that they will be impelled downwardly by their springs 58 to deliver a blow or blows upon the upper and force it against the margin of the innersole, as shown in liI` 10. In the treatment of cemented parts a blow is very effective for securing irin adhesion between theparts .forced into contact by the blow. The operatio-ndescribed is repeated as often as necessary about the periphery of the toe and sides of the shoe to last all parts of the upper.
At the heel it is not desirable to tension the upper but to lay it in contact with the heel seat by an action which begins at the edge of the sole and extends inwardly to lay the margin of the upper against the heel seat progressively from the edge inwardly. Accordingly, when the heel seat is reached the operator will lift the last support 21 until the detent 28 snaps into the groove 27. Movement of the detent 28 will cause the detents 110,117 to arrest action of the gripper member 65, the wipers, of course, being in operation. The work, with the crown of the last resting on the head 21 of the support, is then adjusted, if necessary, as shown in F ig. 11 by pushing the handle t0 and turning it in the required direction. The wipers 4:8 then advance as shown in F ig. 12, to wipe in the margin of the upper about the heel seat, and for each wiping movement the rack 36 is operated to effect upward movement of the last support and cause the overlaid margin of the upper to be pressed forcibly against the wipers 3S, the upward movement of which is limited by the surface 64 (F ig. 18).
