To all whom imag concern:

Be it known that I, MATTHIAS Bn'ocii, a citizen ot' the llnited States, residing` atBoston, in the county of Sinti'olk and State of Massachusetts, have invented certain Improvements in Lasting-lvlachines, 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 gures.

This invention relates to lasting machines and particularly to machines of the type ivhich employ end embracing Wipers and an object ot the invention is to provide an end lasting machine which is more or less auton'iatic and the instrumentalities of which are lso arranged and related that a toe portion, tor example, of a shoe can be lasted and it desired fastened, with a high degree of eftectiieness and a minimum of expenditure of time` labor and Skill by the operator.

One import-ant feature of the invention consists in the combination ot toe lasting plates oi' Wipers and means for operating them by power or otherwise, oi shoe han- (llingv means and power driven or other means 'for operating the handling means to seize a shoe. vertically move the last with relation tothe Wipers and advance the'last under the Wipers. Grippers or theiil lequivalent inay or may notrb'e employed. to hold the margin of the upper-'While the shoe han-y dling means depiesses the last relatively7 to the wipers and the handling means may or may not raise the shoe to iron down-the overivipednpp'er between the last bottom andthe loiver face of the ivipers. The advance oi: the shoe under the Wipers may Conveniently take the place ot the usual movement of the Wipers lengthwise over the shoe. In a power driven machine there may advantageously be provision for the machine to come automaticalvly to rest after the upper along the side faces ot the toe has been prepared tor the action of the Wipers by the described movement ot' the shoe handling mechanism.. Preferably, and in accordance With another feature of this invention, there are t\vo Separate poiver drivenv means for operating the Shoe handling means to advance the shoe under the Wipers and for closing the Wipers. s I am advised, it is nenv lin a lasting' mal chine to provide separately controlled power driven means tor operating the shoe handling' means and tor operating-end lasting ivipers. F or effecting economy ot time in operation, the Wiper closing means may cause the shoe handling means to draw the shoe under the ivipers and, after the Wipers have closed, to raise the shoe for ironing down the overlasted upper materials automatically by compressing the overwiped' upper against the bot-tom tace of the Wipers. The Wiper operating mechanism may come automatically to rest with the Wipers closed over the shoe to give time for the upper Jfastening operation and, at the Will of the operator, said mechanism will return the Wipers `to stzirting position and Will automati- 'ally restart the shoe handling mechanism and cause it to restore the shoe to initial position and release it. As I am advised, it isY nenv to provide Wiper operating means arranged to canse shoe handling means automatically to become operatively connected with a source of poiver for proceeding with its Work after the Wipers have done their Work.

An important feature of this invention is also found in the slioe handling` means. This means isvshown as compri-sing an nnyieldingly mounted shoe bottom rest and an op-l posed toe rest Which is unyiel'dingly :actuated toivard the bottom rest to clamp the shoe after ivhich the said rests are positively actuated Ator giving the required movements to the shoe, As I am advised, it hasvnot heretofore been proposed in an automatic toelasting machine. to provide shoe handling means which clamps a toe rigidly and is positively operated to predetermine the position .of the shoe during` the lasting operation. It is also broadly new to provide automaticor other mechanism for operating the shoe handling means to advance the shoe under the Wipers, as herein disclosed, in combination. with means to operate the Wipers, as for example, in time relation With the movement of the shoe handling means.

Others features of this invention are found in the grippers herein disclosed which have many novel characteristics of construction and arrangement and sustain many novel rel-ations to the other instrumentalities of the, machine. Advantageonsly the gripper mechanism comprises grippers arranged at the corners and sides ot the toe loutnot atA the tip end of thc toe. It is new to provide, in combination with toc lasting wipers, grippers or other means arranged to hold the edge of the upper at the corners or at the sides of the toe while shoe handling means is operated automatically to seize the' shoe, depressthe last with relation to the upper so held and then to advance the last. It is also new to provide mechanism comprising corner or side grippers and means to swing said gripper mechanism inwardly over the last bottom like an end lasting wiper swings, whether or not the grippers are connected with such wipers to partake of their. movement and either with or without alast advancing movement in time relation with such swinging movement of the grippers mechanism. Another novel characteristic of a gripper used with a wiper is found in the provision of a vertical slot in one of the gripper jaws andv a vertical crimping blade cooperating with the slotted jaw to gather the upper. This crimping action is particularly advantageous in the gripper located at the corner of the toe.

A further feature of this invention consists in the combination of wipers .having binder wire carrying devices or formations, such for example as grooves in their acting edges, of means to place a toe binding wire in said devices or formations, as for example by bowing the wire progressively or otherwise and pressing it into the grooved edges of the wipers. l

These and other features of the invention, including various combinations of parts and more important details of construction, will nowv be described in connection with drawings illustrating the preferred embodiment of the invention and will then be pointed out in the claims.

` relation will be more fully stated in an explanation ofthe operation of the machine.

The shoe handling mechanism includes the toe rest 2 and the last depressor 3 carried in a frame of general rectangular shape shown best in Fig. 2 where 4L is the cross-head casting, 5, 5 are the side bars and 6 is the foot 1ece. p `The last depressor is rigidly mounted in the cross-head 1, in which it is vertically adjustable by the nut 7 and is secured by a lock nut 8, and its foot 9, Figs. 3 and 5, is pivoted to its stem by a transverse` pin while the sole engaging plate 10 thereof, which is contoured to t snugly within the channel rib or lip of a welt shoe innersole, is made right orl left and is removably attached to the foot by a stud 11, Fig. 5, and a headed spring pin 12 carried by the foot and fitting in a countersunk keyhole shaped slot in the plate, the spring on the pin allowing Jthe plate to snap over the stud. The plate is concave on its lower fac-e to apply pressure through its marginal portion to the innersole adjacent to the channel lip for holding the innersole down and resist-ing crumpling of the innersole at. the channel while the upper is being lasted over the feather edge of the innersole. An adjustable stop screw 13 is arranged in the foot t0 contact by its head with the stem 3 to limit the tipping of the foot downwardly at its front end by gravity.

-The toe rest 9. is a block of suitable material which will not bruise or abrade the shoe upper, and it may be rubber, set into a holder 15 that is guided in the head 16 to slide in an arc which preferably has its center in about the plane of the last bottom. The head is adjustable, by a screw and a nut 18in the toe post 20 toward and from the last depressorto adapt it for the thickness of the style of last and if the block be of rubber it will yield enough to adapt the rest to two or more sizes of the same style fof last. A fork, Fig. 5, depending" from the head 16 embraces a rod Q2 to prevent the head from turning.

The rod 22, guided in vertical slots, Fig. 1, in the side bars 5 of the shoe handling frame, extends through the post and to it are pivoted the upper ends of the members 23 of toggles, the lower members of which are arms 24 of angle levers 25 pivoted on the rod 21 of thefoot piece 6 of the frame to lift the toe rest within the frame for clampingthe shoe against the last depressor 3. f-

The foot piece comprises not only the rod 21 on which the angle levers are pivoted and which is pivoted in the lower ends of the side bars 5 but also a depending yoke 19, Fig. 2, from which extends a rigid arm 17 curved upwardly and then projected inwardly to a bearing on axle 32, Fig. 1, in the body of the machine. By this yoke and arm inward and outward movement of the fulcrum rod 21 for the toggle levers 25 is prevented while there is freedom for swinging movement of the shoe handling frame to carry the shoe into and out of the machine and for vertical movement of the frame. The normal vert-ical position of the shoe handling frame is determined by link connections l5 with arms 46 of a rocking sleeve that turns on a pivot rod 47 and has a depending arm -19 engaged by an edge cam face i8 of a cam block 30 that is turned on the axle 32. rlhis cam block 30 has gear teeth by which it is turned by a pinion 35 of one-half its peripheral size. The pinion is formed on a sleeve that carries a spring-pressed clutch pin 36 by which the pinion may be coupled to a collar 38 on the continuously ruiming driving shaft 40 car rying the belt pulley 39. A clutch controller lever 4:2 for the described parts is formed with a pin retracting and seati-ng wedge on its upper arm and its other arm is connected to a treadle 44, Fig. 1.

The angle levers 25 above mentioned are connected by links 26, Fig. l, with a lever 27 that extends from a rod 137 at the back of the machine and has a roll standing in a cam track 2S cut into the inner face of the cam'block 30. Movement transmitted from this cam track straightens the toggle for raising the toe post, the latter having a slotted connection at its lower end with the rod 22 to clamp the shoe up against the unyielding and then stationary last depressor. After the gripper-s have seized the margin of the upper that extends about the toe, the shoe handling frame with the toe rest and last depressor, is moved downward to stretch the upper between the grippers and the last by a continued movement transmitted from the cam groove 28 through the lever 272 which, after straightening the toggles, engages the arm 17 to draw down the foot piece 6 and the entire handling frame and the shoe on the last now held by the frame. The edge cam face 48 is shaped to permit this downward movement of the 'shoe handling frame.

By this movement the shoe is carried down until the plane of its bottom face, determined by the last depressor, is below the plane of the wipers. All this occurs during one-half rotation of the cam block 30, producedv by one complete rotation of the driving shaft 40, and here the cam block is stopped by the withdrawal of the clutch pin 36 and its arrest by the clutch controller lever 4t2 which, after the depression of its treadle, will have been returned to proper position by a suitable spring.

After the now stretched upper has been inspected the shoe handling frame is swung inwardly toward the body of the machine to move the shoe longitudinally under the wipers by links Fig. 1, extending from the rod 22 backwardly into the machine to a lever 5G depending from rocking sleeve 16st on a pivot rod 57 and connected by other links G2 with a depending arm of a rocking sleeve shaft 6() fulcrumed on the pivot rod G72 said arm having a roll standing in a track 5S cut in the side of a cam block the driving connections for which will be described in connection with the wiper mechanism.

The shoe handling frame is further elevated after the shoe has been moved under the wipers, the wipers having meanwhile been closed, to compress the overwiped upper and innersole between the wipers and the last bottom. For this purpose the rocking sleeve, that hasthe depending arm 49 and is connected to the shoe handling frame by the arm 1G and the links l5, has a second depending arm 69 bearing a roll which is engaged by an edge cam face GS formed on the cam block 70. It. will be understood that the cam t 'ack 28, by which the shoe handling frame is sustained while no other devices are upholding or uplifting it, is so formed with relation to the edge cam face GS as to permit the described elevating' movement, and that the edge cam face G8 has a low por tion which permits the depressing movement effected by the track cam 2S, the cam blocks 30 and 70 being each at rest while the other is moving.

The grippers comprise jaws arranged in a line corresponding approximately to the curvature of the toe and include one pair of jaws located to engage the upper at each corner of the toe and, prefenbly, also one pair located to engage the upper at or near the rear end portion of each wiper, making four in all, there being no gripper to pull the upper at the end of the toe where it is expected that the toe gripper of the pulling over machine will have stretched the upper sufficiently so that no pulling by a gripper is needed in this lasting machine. It is regarded as probable that modifications varying widely from the illustrated construction and arrangement of gripper-s may be employed in this machine to secure the advantages herein obtained and the invention is therefore to be considered as limited in this respect only as required by the broad terms of the generic claims.

The two grippers or two pairs of jaws for each side of the work are mounted on a carrier 100 to which each gripper guide 102 is pivoted at 103 to swing in'and out about an axis approximately tangential to the adjacent edge of the toe and located high 'above the shoe bottom. An abutment screw 104 for each gripper' determines the normal upper seizing position of the jaws individually for the size and shape of the toe. Within each guide 102 slides endwise a gripper stem 105 that can turn on its longitudinal axis for allowing the jaws to adjust themselves to the direction of strain. The stem has a foot 106 in the front edge of` which, and offset inwardly from the axis of the stem, -is secured a rigid jaw 108 to engage the outerl side of the upper. The pivoted inner jaw 110 is formed as an angle lever fulcrumed at 112 and its outwardly projecting arm extends through the foot 106 and ispivoted to an operating rod 115 that extends up through the guide 102 and a jaw opening spring 114 pulls the rod downwardly. Within the guide 102 the stem is encircled by a spring 116 that holds the stein 105 and the jaws down in shoe receiving position until the jaws have rmly gripped the upper after which it yields for the upper pulling movement.

The closing of the jaws is effected by a shouldered block 120 that embraces the operating rod 115 and acts upwardly upon it through a cushioning spring 121. The shoulder of the block is engaged by a slide 122 that is confined in the carrier 100 and rests down upon the broad head of a plunger 125, there being one plunger for the two grippers at the same side of the work. The plungers extend down and rest on arms 124 of a rocking sleeve 128 on pivot rod 127. Another arm of the rocking sleeve 128 is connected by a rod 129 with a lever 130 that is fulcrumed on pivot rod 137, and has a roll standing in a cam track 138 in the outer face of the cam block 3 0.

Through these connectionsl the cam block 30 closes the grippers to seize the margin of the shoe upper and then slightly uplifts them to straighten up the stock after the shoe has been clamped by the rise of the toe rest and before the shoe is drawn down by the depression of the shoe handling frame during the second part of the movement of lever 27 derived from cam track 28.

The gripper closing lever 130 has a stud 132 located to be engaged by a spring-impelled latch 134 on a sleeve 140 that is pinned on an axle 147. To this axle is also pinned a second sleeve1 Fig. 8, from which extends an arm 243 into the path of a stud 245 on the outer side of the cam block 70. The arrangement operates to lock the grippers closed while the cam block 30 turns beyond the closing point to where the roll on lever 130 is in a wide part of its cam, track. Thereafter and subsequent to the beginning of the operation of the wipers the cam block 70, through its stud 145, disengages the latch 134 from lever 130 to permit the grippers to open and free the edge of the upper for the completion of the over lasting operation of the wipers. A

The wiper plates 150 are vertically slotted at their rear ends to embrace studs 152 in the slotted wiper carriers 154l in the front ends of which are mounted upwardly spring pressed locking pins 155 to engage pin holes in the wiper plates and lock the plates into the carriers.

The wiper carriers 154, Fig. 3, have outer edge faces lcurved about a point located at the meeting edges of the wipers and the carriers are guided i-n similarly shaped ways in the machine head where they are confined by the cover plate. Each carrier 154 is connected by a link with the cross-head of a plunger 156 that has a threaded adjustment in a sleeve 158 confined in a block 160 that can slide in the machine head and is actuated by an arm 162 of the rocking sleeve 60 that turns on the pivot rod 67 and has a depending arm with a roll standing in the cam track 58 as described in connection with the inward movement of the shoe handling frame,- see also Fig. 7.

'These connections operate to close the wipers, but not to advance them, while the shoe handling frame draws the shoe into the machine and under the wipers.

The gripper carriers 100 for each side of the work are connected to the respective wiper carriers 154, the gripper carriers having for this purpose bases 151 guided in` arc-shaped ways 165 in the coverplate and connected by bolts 166 extending through slotsin the cover plate to the wiper carriers 154. Thus the grippers partake of the closing movement of the wipers. They, like the wipers, have no movement longitudinally of the shoe but the shoe has the described advancing movement relatively to the grippers just before the grippers release the upper. v

lThe wipers and the grippers are adjusted for sizes of'toes by the sleeve 158 andits threaded connection with plunger 156, the sleeve having a pinion 17 Oconnected by an idler with a gear 172 on the hand shaft 174 to the front end of which is attached a hand wheel 175. This adjusting mechanism may be used towmove the wipers manually after their automatic closing movement if supplemental operation of them should in any case be found necessary. j

It may be advantageous to have the wipers stand wide open in shoe receiving position to give abundant clearance for the ywork of positioning the upper within the grippers. It is desirable, however, that the wipers stand close to the last at the end of the jacking operation and preparatory to their lasting movement. To secure these results without excessive use of the adjustment provided by the hand wheel 17 51 which it will be understood is to be used whenever needed to position the wipers preparatory to their lasting movement, the pinion 170 has an eX- tension 171. This extension is engaged by a rack 173 connected, Fig. 1, with a lever arm 175 of sleeve shaft GO, anothery arm of which is connected by rod 179 with the jacking lever .27 to close the wipers a limited distance by movement derived from the cam block 8O during the jacking of the shoe. A wedge 181 stands in the lpath of a pin 183, Fig. 8, on the rack bar 173 and withdraws the bar from the pinion 171 at the end of the downward stroke of said bar so as to leave the pinions 171 and 170 free to be adjusted by the hand wheel 175.

The cam block 7 O 'by which is effected the final closing of vthe wipers, the advance'of the shoe into the machine, the release of the grippers and the ironing down liftl of the shoe, is given rotary movement from the driving shaft 40 through a' clutch connection with thel collar 38 on said shaft manipulated by a clutch, controller andy treadle' 14:4: similar to the clutch, the controller' and the treadle flat described in connection with the caniblock 30. The cam block carries a pin 145 to engage an arm 143 on a sleeve 1111 that turns on the sleeve 140 and its companion sleeve, Fig. 87 and is connected by a rod 1-19 with a rearwardly extending arm, Fig. 1 ofthe clutch controller lever '112. Bythis arrangement the cam 7 0'. during the second half of its rotation in which the pin 145 is timed to engage arm 143, trips the clutch for cam block 30 and causes that cam block 30 to complete its rotation for automatically unjacking the shoe and returning the parts controlled by that cam block to starting position.

The wipers are grooved in their operative edges to carry a toe binding wire which is led from a reel, not shown, on the left hand side of the machine through la friction guide 180 located in the plane ofv the groove to a clamp 182 which is located in the plane of the groove at the right hand side of the machine. The clamp and the friction guide position the wire in a line across the open wipers. A binder bending and placing roll 185 is mounted on a curved Iarm` 186 that is pi'voted to a curved arm 188y which is in turn pivotally supported on the right hand side of the machine head as shown in Fig. 3, a spring 187 being provided to hold arm 186 normally swung to the right toward the arm 188. j

of less thickness than the depth of th'e groove in the wipers and it is located in the same plane in which is the groove in the wipers and in which the guide 18.0y and clamp 182 hold the wire. By a handle 190 on the arm 188 the operator swings the arm to cause the roll, which has a grooved pe-1 The binder placing roll 185 is ripheral edge, to engage the wire, bend it, and carry it into the groove of the wipers. The jointed connections of arms 186 and 188 and the spring 187 cause the roll to thrust the wire into the vright hand Wiper first and then to roll along and bend the wire and seat it in the left, hand wiper. In this wire placing operation the required quantity of wire is drawn through the friction guide and bowed into the groove in the wipers where it is retained automatically because its ends are confined against movement.

The jaw 108 of the corner grippers preferably has a vertical slot through it as shown best in Fig. 6 and the coperating jaw at 110 has a vertical crimping plate 111 which moves into the slot when the aws are closed and thereby gathers the edge portion of the upper at the corner' of the toe and holds it in that condition for the-action of the wipers. It is found that this combination of toe embracing wipers with grippers constructed and operating as described at the corners of the toe is effective to produce smoothly lasted toes in a lasting machine of the type herein shown.

A support for the rear part of the last may or may not, be attached to the toe post 20 for vert-ical movement as in Figs. 1 and 3 where it is shown as comprising a rearwardly projecting bar 194 pivoted to the toe post at 195 at a point which is approximately under the joint of the last, or the point of intersection of the median lines of the forepart and the heel part of a crooked last. The upper face of bar 194: constitutes a downwardly and rearwardly inclined guideway for a block .196 upon which a last pin 197 is carried at an angle to compensate for the spring of the last and hold the shoe with the bottom of its toe end in a. plane parallel with the plane of the wipers.' The last pin braces the shoe against rearward displacement between the toe rest and the last d'epressor during the advance of the last under the wipers. An eccentric friction lock 198 clamps the block 196' on bar 19'1 at the righ-t distance from the toe rest for the length of 'the shoe and the upward inclination of said bar 1.94 compensates for differences in height or thickness of large and small shoes.

The bar of the last depressor or bottom rest 3 may be jointed to allow the depressor to swing' out and up to the position sho-wnv` `main will be ii'iserted endwiSe between the toe rest 2 and the bottom rest 3, the toe rest being in the depressed position shown 1n Fig. 1. This will bring lthe shoe into the relation to the wipers and grippers which is best illustrated in Fig. 4. The wipers may -or may not closely embrace the shoe at this time. In turn work they should not do so because the projecting edge of the sole of a turn shoe would be in the way during the 'clamp the shoe against the bottom rest by reason of the straightening of the toggle 23, 24. Thereupon the grippers will close and be slightly uplifted to .straighten up the upper. f After the grippers have closed the entire shoe handling frame, including the toe rest andthe bottom rest, is moved downwardly to depress the last to aplane in which the shoe bottom is slightly below the wipers. During this movement of the last the grippers tighten the Aupper to prepare the upper along the side of the last for the overlaying operation of the wipers `and then the machine is brought automatically to rest by the action of the clutch controlling lever 42 upon the clutch pin 36. The operator now examines the shoe to ascertain that it is in lstretched condition so that when the upper is overlaid by the action of the wipers it will be smooth and free from wrinkles. It will be seen from Fig. 5 that for this purpose the machine is constructed with clearance `about the toe so that the operator can, with his lingers, feel the upper entirely around lthe toe of the last. When the shoe is found .to be in condition for the operation to proceed, the right hand starting treadle 144 is depressed and the cam block 70 thereby started into motion, the cam block 30 which Ialone was vpreviously actuated through onevhalf onlyof a revolution now remaining at rest.

with., the'advance of the shoe, the grippers partaking of the closing movement of the wipers and after this movement has proceeded far enough for the upper to becomeV gripped between the wipers and the last bottom,. the grippers are caused to release their hold uponthe upper. Finally the shoe is given a4 slight upward movement to compress the overwiped upper against the bottom faceof the wipers. The machine will now come to rest automatically if the operator has removed his foot from the treadle 144. Vhile the machine is at rest, the toe ybinding wire at the right hand side of the machine, Fig. 7, may be pulled out of the clamp 182 and anchored to a tack at the right hand side of the shoe bottom and then pulled out of clamp V180 and drawn tight around the toe to fasten the upper in the position in which it is being held by the wipers. In another use for which the machine is adapted the free end of the toe binding wire will be anchored to a pullingover tack at one side of the shoe before the upper is wiped over the innersole and at the proper time, and without stopping the machine, after the upper has been overwiped, the wire will vbe tightened by tension applied to it at the other side of the shoe and starts the cam 70.- The first result is to lower the shoe1 by a positive downward movement kof the shoe handling frame.

Y, Thereafter thewipersbegin to back off and the shoe to retreat from under the wipers. During this movement of the cani block the tripping devices 132, 134 cause the clutch controlling lever 42 to be automatically tripped for starting the cam block 30 which now completes its revolution to actuate the v`shoe handling means to return the shoe handling means to initial position and operates it to release the shoe whereupon the machine comes to rest with the parts in the positions from which they started. After the shoe has been `removed and before another shoe is put into the machine, the toe binding wire will be drawn intol the clamps 180, 182 and the wire placing means 185 manipulated to bend the wire into bowed form and place it in the wire holding groove in the acting edges of the wipers.

' Having explained the nature of the invention and how it mayvv be embodied in the best form now known to me, I claim as new and desire to secure by Letters Patent ofthe United States protection commensurate to the real breadth of the invention and intend that the following claiming clauses shall be construed to give effect to this purpose.
