HEEL-BUILDING HZACHINE.

Application filed December 29, 1915, Serial No. 67,81

To all whom may we "a: I

I Be it known that 1., En. E. lViNnnnY, a citizen of the United Mtates, residing at Lynn, in the county of lfils ez; and State of Tiassaclmsetts have invented cer in new and useful Improvements in Hee -Buildin;g lilachinesz, and it do hereby declare the following; to be a full, clear, and exact description of the invention such as will ei'iable others skilled in the art to which it appertains to make and use the same.

'lhisinvention relates to heel i achines, and more particularly to such machines for preparing heel blocks for the heel compress-- i119; operation by assembling pasted lifts of heel material into a block of the proper contour and subjecting the resultant shaped heel pile to pressure for a surlicient length of time to insure the setting of the paste. although many features of the invention are applicable to machines of widely diile'z ent characteristics.

It has heretofore been the practice to semble the pasted heel lifts in a suitable matrix. or former, and then to transfer the pile so produceo manually from the former to a pressing machine, in which it is held under pressure while the paste dries and sets. In accordance with this mode of operation it has been found necessary to drive one or more nails through the heel lifts in order to hold them temporarily in their correct as sembled relation while the pile is being transferred from the former to the press.

One object of the present invention is to combine the assembling and pressing instrumentalities in a. single unitary machine in such a manner and relation that the na'ilin operation may be eliminated -Accordingly a feature of the invention comprises the combination with a seriesof intermittently movable heel blocs holders or presses, of heel-former for shaping pasted heel lifts into the proper contour of block and movable to transfer the shaped blocks to the presses. The press'structure and heel-former are so associated and operated that the pasted heel pile is delivered directly to the press from the formcn and by the movement of the former. the alined h eel pile remaining under the control of the former until it has been seized by one of the movable series of pres t-s. The construction of the heel-former. 'Tlii) manner in which it is actuated, preferably in CC"O1CI'L'L- Renewed July 10, 1922. Serial No. 573,917.

tion with a second heel-former and the release and withdrawal thereof from the clamped heel block so that a former may constantly be presented 1n receiving position.

all form features of novelty in the combina* the moving parts as to successively prepare the presses for the introduction of freshly shaped heel piles at each forward step of the series of presses.

A further object of the invention is to improve the construction and operation'of heel pressses of the type referred to in such manner as to provide for speed in operation by reducing to a minimum the weight of the moving parts, and for efficiency through an accurate control of the individual presses. One means to this end is the provision of heel clamps each normally held closed, preferably by a spring, and co-operating clamp opening means that operates independently of the advancing movement of the clamps. After being opened against the opposition of its closing device, each clamp is held open for ejection of the pressed heel block and until it is loaded with a new heel block. A further means by which an eflicient and accurate ooeration is attained is a design of the mac ineproviding for all the operations upon the clamps and the ejection and loading of the heel blocks during the brief periods of rest of the intermittently movable endless series of heel presses.

Other objects of the invention, and the features of construction and oaeration b which they are attained, will be readily apparent to those skilled in the art from the followingdescription of the preferred em bodiment. Theinventiom in its broader asoects is not confined to the siecific structural details and mode of operation set forth, and the advantages and. benefits there of may be attained by machines differing widely in certain respects from that shown and described. Nor is the invention limited to the conjoint use of all its features, and it will be understood from this specification that it is within the scope of the invention to use some features without others or tocoinbine the various features in rlitfer-- cut manner than is described as the pre ferred combination. Thereofore, only such ill) limitations should be imposed as are indicated in the appended claims.

In this specification the term heel lift is used inclusively to designate pieces of inaterial,"of whatever nature they may be, that are utilized as the components of the heel being built, and the term heel block is used to designate the product obtained by piling the. pasted lifts prior to the compressing, operation, that is, either the freshly pasted heel pile, which is a wet or green heel block, or the dry, pressed heel pile ready for the heel compressing operation, in order to distinguish this article from the comiueixial heel blank which is a product of the. heel compressor.

The preferred form of the invention is illustrated in the accompanying drawings,

In the embodiment of the invention illustrated in the drawings the machine is shown as having a frame composed of a vertical front plate 2 and a rear-plate 3 4 and 5) which are spaced in parallel, fixed relation by an intermediate box frame 4, suitably secured to the vertical plates. The rear plate 3 and the front plate 2 have their uppermost edges in the same plane, but the clutch member on the pulley 10. i The shaft- 11 is supported in journals in the frameof the machine, and is provided on its inner end with a worm 14 (Fig. 2) which meshes with and drives a worm wheel 15 secured,

which are adapted to mesh, once in each revolution of the shaft 16, with a complementary interrupted gear 21, which is fixed on a transverse shaft 23 journaled at the left hand ends of the plates 2 and 3. The gear 21 has a plurality of sets of teeth disposed on successive. equal, separated arcs. This mechanism will be recognized as the ordinary Geneva stop motion.

The shaft 23 also carries a pair of spaced sprocket wheels 2%, arranged in common vertical planes with a second pair of parallel spocket wheels 26 which are secured. at the right hand end of the machine, on a transverse shaft 27 (see Fig. 1). pairs of sprocket wheels are connected by parallel sprocket chains 28, the upper stretches of the chains running approximately in the horizontal plane of the upper edges of the front and rear frame members 23. i

The matrices or formers in which the lifts are deposited are mounted at the upper front portion of the frame, upon a forwardly projecting shelf 30 (Figs. 2, 4: and 7) to which is secured a removable base-plate 31 having Ways 32 provided for the sliding movement of right and left hand slides Each slide 33 has a. horizontal body'por'tion, runningin the slide ways 32, and a perpendicular side wall 34-. To the top edge of the wall 3 1 is secured a plate 35 which. projects horizon tally over and somewhat abovetable 36 which is secured, by screws 37, to the central portion of the base-plate 31. The former in which the lifts are successively piled, or in which a green heel block .may be deposited, comprises two members in the form of arms 39. These arms are pivoted, at their forward ends, on studs 38 depending from the plate 35, andthearms rest upon the tablet-3G. Each of the arms 39 is provided witha perpendicula-r breast'gage surface 40 and one or more side gaging surfaces 11, 12 which latter are formed according to the style and shape of the lateral surface of the heel to be built. As shown' in Fig. 6, the breast gages 40 are ina common vertical-plane and the rear ends of the arms 39 are providetl with gage surfaces -12 which are inclined in wardly and, downwardly inconforn'iity :to

The two the pitch of the heel to be produced. The intermediate side gages ll are also inclined inwardly and downwardly to fit the sides of the heel. With this construction, the matrix or heel-former will effect a transverse or edgewise shifting into alined position of individual heel lifts superposed in the matrix, or will transversely shift the component lifts of a green heel block which may have been built outside of the matrix and then placed therein, and thus properly aline the lifts for the subsequent heel compressing operation.

For the purpose of automatically closing the matrix arms 39 into receiving position (Fig. 6) each arm is provided with a lat orally extending cam lug 45. Vhen the slide 33 is moving toward the front of the machine the lugs engage fixed abutments 46 on the top of the base-plate 31 and the assembling table 36 whereby the aws or arms 39 are swung toward each other, about their pivots 38, to the position shown in Fig. 6, whereupon they are automatically latched together by a spring catch 47 pivoted on one of the awe and engaging a keeper 48 on the opposite jaw.- (hen the arms are latched together they closely embrace a lug 50, which depends from the plate 35, and this lug acts to centralize the former and the heel-pile held therein. The out-ward, or opening, movement of the former jaws 39 is limited by step pins 51 carried by the plate 35. The surface of the table 36 provides a support for the lowermost lift of the heel block.

It is a feature of the present invention that an operative can work to continuously supply heel lifts to former without having to wait on the operation of the machine to bring former to receiving position, and for that purpose the two formers are moved alternately to carry to the presses a completed pile of lifts, so that one or the other of them is out in the filling, or lift receiving, 1. osition all of the time.

For the foregoing purpose each slide 33 is connected, by a pin 59, to a link 60 (Fig. 3) which extends rearwardly and is connected to the upper end of a cam lever 61 (Fig. 8) which carries arolle'r 62. The roller 62 of the right hand former slide 33 operates in a groove formed in a cam disk 63 secured on the shaft 19, while the roller 62 of the left hand former operates in a groove formed in a cam disk 6% on the shaft 19 (see Fig.

Both of the formers must be out of the path of movement of the presses during the intermittent adi'ancing movements of the latter. In order to economize in the time of operation the conveyor is moved, at each op- 61'2Il3i011,tl1101lgl1 the space of two presses, and prior to such movement each of the two formers. after having received a heel-pile, or a series of heel-lifts assembled therein, is rellldCllGLi to deliver the heel-pile to the corresponding press. Thus two presses are loaded and two are discharged during each dwell of the conveyor, and then the two formers are brought to their forward posit-ions to permit the filled presses to be moved away, and the two presses from which heels have just been discharged to be brought into cooperative re lation with the formers.

After a heel block has been built as described in one of the formers it is carried rearwardly by the former, across the table 36, and deposited in a heel block press. Fixed to the chains 28 are a series of press plates 7 0 each carrying a press structure so that each press is moved by the conveyor, which is formed by the press plates and the endless sprocket chains 28, through a continuous orbit. lVhen traveling in the upper horizontal stretch of the orbit, adjacent the top the machine, the ends of the press plates slide upon parallel. supporting rails 71 which are secured to the upper edges of the front and rear frames 2 and 3. These rails serve the purpose of supporting the upper stretch of the endless conveyor and also insure the proper alinement of the press structure with the matrices.

Integral with each press plate 70, adjacent the rear end thereof, is a depending bracket 72 which supports a heel block receiving bed 73 (Figs. 4 and 5) the surface of which is maintained by the supporting rails 71, while the plates 7 O bear thereon, in substantially the same plane as the top of the table 36. The front edges of the bed plates 73 run close to the rear edge of the table 36 (see Fig. 6) so that, when a matrix is shifted across the table 36 the heel block carried therein may easily be placed on the bed plate. It will be understood that the bed plates are intermittently held stationary in heel block receiving position by the Geneva stop mechanism herei before referred to.

After a heel block has been transferred from the table 36 to a registering press bed plate 73 (Figs. f and 5) it is then clamped thereon by a platen 74, of suitable form, which is mounted on the lower end of a stem 75 (Fig. 10) which slides vertically through the press plate 70. This stem is automatically pressed downward by an expansion spring 76, mounted upon the reduced upper portion of the stem 75, and is guided in an upper bearing 77 against which the upper end of the spring 76 abuts.

For the purpose of lifting the platen T l at a predetermined position of the press in its orbit, there is clamped to the upper end of the stem 75 a collar 78, to which is pivoted, at 79, the upper link 80 of a toggle, the lower link 81 of which is pivoted at 82 on the upper side of the press plate 70. When the toggle 8081 is straightened it operates to lift the platen 74 against the force of the spring 76, and when the toggle 80--81 is broken (as in Fig. 10) the spring comprise a lever 84 (Fig. 4) loosely pivoted upon a pivot rod 85 which is mounted above the top of the framein a pair of end brackets 86. The lever 84 cooperates with an arm 83 projecting rearwardly from the lower link 81 of the toggle, and it has a rearwardly extending arm which is connected, at 87, tothe upper end of a vertical actuating link 88 (Fig. 8'). The link 88 is connected, at its lower end, to av bell crank cam lever 89, which is pivoted upon a pivot rod 90 supported, at its ends, in the frame legs 66. This pivot rod also supports the cam levers 61'. One arm of the bell crank 89 is provided with a roller 91 which operates in a groove in a cam disk 92 mounted on the cam shaft 19. The cam 92 is so designed that,

after aheel block has been shifted by the former into one of the presses aline'd therewith, the link88 will descend, rocking the lever 84' in a direction to engage and lift the overhanging arm 83 and thus breakthe toggle 8081. As hereinbefore' explained this permits the press spring 7 6 to forcethe press platen 74 downu' ard on top' of the heel block, while held in the former. I After the tripping lever 84 has been actuated by its cam 92 to break the toggle the cam 64 operates to return the former to its heel block receiving position on the table 36.

Before the former can be moved outwardly by the action of the cam 64, it is necessary to first trip the latch 47 so as to permit the arms or aws 39 to swing outwardly on their pivots 38 to disengage the heel blOClQWVl'llcll at this time is firmly clamped in the press. This is accomplished through the means of the former actuatinglink which, in the initial portion of its outward movement under the action of its cam 64, operates to carry an adjustable lug or striker 95' (Fig. 6), fastened on one side thereof, into engagen'ient with the tail 96 of the latch 47. This swings the latch about its pivot in a direction to unlock the jaws 39' of the former. in advance of any shifting moveinent of the latter.

This initial motion, to permit the preliminary unlocking of the latch 47, is provided for by slotting the forward end of the link 60 as at 97 (Fig. 4) Where it connects with the pin 59, so that the link may have the requisite motion to move the latch 47 before any movement is impartedto the slide After the link 60 h'as'been' moved suiticiently by its cam 64 to cause the preliminary opening of the latch 47, its continued forward movement operates to shift the slide 33 outwardly, and the former arms 39 swing outwardly as'their surfaces move the' continued forward movement of the slide 33, the pivoted arms 39 of" the former are again swung together as their cam surfaces 45 arrive in contact withv the fixed abutments 46.

It is desirable'that, afterthe' slide 33 has retracted the former to its filling position, the operating link 60 thereof be slightly retracted to again take up the lost motion at 97 so that when the slide is to be again shifted inwardly this transfer movement will occur positively without loss of time. This result is obtained by so designing the cams 63 and 64 that at one point, as 98 of each (Fig. 8), their cam grooves are effective, after the cams have turned through the angle necessary to project the slides 33 forwardly, to reverse the motion of the act'uating links GOjust sufficiently to take up the play the slots 97 and then holdthe links 60 in this position.

In practice, with both right and left hand formers in filling position, the operative will first charge the left hand former with pasted lifts to form a heel block and then in due time, the filled former will automatically move inwardly to deposit the heel block in a press structure. Meanwhile the operative .1

will be filling the right hand former while this is still maintained in its filling position. Before the right hand former is moved inwardly by its cam 63, the left hand former will have been brought forward again by its cam 64', the lever 84 in the meantime having been operated to permit the automatic closing of the press platen 74. When the right hand former is shifted inwardly over an alined press bed plate 7 3, the platen toggle members will be broken through the agency of another unlocking lever 99 engageable with the registering press arm 83,. operated in the manner, described for the lever 84, by a cam 100 which is timed to release the platen to the control of its spring just at this time. As soon as the platen 74 has been automatically closed to clamp the heel block to the bed plate 73, the cam 63 operates to move its link 60 forwardly with the consequent operations on the former hereinbefore described.

With the cams 63 and 64 so designed and disposed that they will operate" to alternately shift first one and then the other of the formers from an outer, or filling, position to an inner, or press loading position and then to maintain them alternately, and for a period ofboth of them simultaneously, in their outer positions, it will be seen that the operative may constantly be filling one or the other of the formers.

The illustrated form of the invention is llli with the formers. a pair of heel blocks which have previously been formed and loaded into the presses and have passed around the entire orbit will have been brought up to an unloading or ejecting station. in the present case just to the right of the loading station (see Figs. 1 and 2). At the discharging station mechanism is provided to unclamp the blocks in a pair of presses simultaneously and then eject the blocks from the machine. The unclamping mechanism comprises a trip lever 105 (Fig. which. is provided with a pair of rigid parallel arms 106 arranged to overhang the toggle-actuating arms 83. The lever 105 is pivoted upon the pivot rod 85, and it has a rearwardly extending arm connected, at 107, to a vertical link 108, to the lower end of which link there is connected a bell-crank cam lever 109, pivoted on the pivot rod 90. The cam lever 109 carries, at the end of its upright arm, a roll 110 which engages a groove in a cam disk 111 mounted on the cam shaft 19. The cam is so designed that during the interval in which a pair of presses are halted at the unloading station, the lever 105 is roeked'so that its: arms 106 will press downwardly against the arms 83, so that the toggle links S081 of the two presses at the unloading station are straightened and lift the respective platens 74. upwardly against the pressure of their springs 76, thus releasing the heel blocks in the presses.

As soon as the heel blocks have been thus released they are ejected from the machine into a forwardly and downwardly inclined discharge chute 115 (Figs. 3 and 5), at the upper front portion of the machine. by means of an ejector comprising a rearwardly extending forked member 117 (Figs. 3 and 41) which is pivoted, at its rear end, on an upright supporting link 118. The ejector is connected to a cam lever 119 which has a roller 120 engaging a groove in a cam disk 121 on the shaft 19. The forward forked end of the ejector 117 is provided with V-shaped faces 122 (Fig. 3) which are arranged to operate in a substantially horizontal plane to engage and eject the pair of heel blocks at the discharging station, when the cam 121 advances the ejector.

The vertical webs 72 of the bed plates 73 are provided with apertures 123 (Fig. through which the ejector ends 122 may move forwardly to engage and eject the heel. blocks. While the conveyer is in motion the ejector 117 is held in a retracted position.

The machine is started and stopped by means of a treadle 130 (Figs. 1 to 41) secured upon a treadle shaft 131 which, by reason of a suitably connected torsion spring 132, continuously tends to rock in a direction to render the driving mechanism inoperative, On one end of the treadle shaft 131 is secured an upwardly extending arm 133 to which is connected a rearwardly extending horizontal link 1341, the opposite end of which is connected to a lever 135 (Figs. 1 and 9), mounted on the pivot shaft 90, and carrying, on its upwardlyextending arm. a roller 136 adapted to interlock with a stop plate 137 secured on the cam shaft 19. The stopplate is formed with a plurality of shoulders 138 for engagement with the roller 136. On the other end of the shaft 131 is an upwardly extending arm 133, connected to one end of a link 13 1 (Fig. 41) the other end of which is connected, at 140, to a lever 141. The lever is pivoted on a stud 1 12 mounted in a foot bearing 143 provided for the outer end of the shaft 11. At the upper end of the lever 1411 a link 1 14 connects the lever to one end of a concaved clutch shoe 145, pivoted at 1 16 upon the foot bearing 113 (see dotted lines Fig. 4). The clutch shoe 1-15 is adapted to engage with a pin 147 which is secured to the clutch member 12.. so as to interrupt the rotation of the latter and thus discon nect the shaft 11 from driving relation with the pulley 10. hen the operative desires to start the machine, he depresses the foot treadle 130. which swings the arm 133 forward. against the torsional effect of the spring 132 on the treadle shaft 131, and shifts the link 1341' forward to rock the lever 1 11 and withdraw the clutch shoe 1 15 from engagen'ient with the clutch pin 147. The clutch member 12 is thus peijmitted to become oneratively enga ed with its complementary member, and the shaft 11 is turned.

The operative'may either continue to hold the foot treadle 130 down or may lock it in its lower position by a lock arm 150. pivoted at 151, which is adapted to be swung horizontally over the depressed end of the readle 130 and thus hold the latter in this position. When the operative desires to in terrupt the operation of the machine the locking arm 150 may be turned horizontally with the foot, so as to release the treadle 13.0. As soon thereafter as the roller encounters one of the depressions in the stop-plate 137, the spring 132 is permitted to rock the shaft 131 in a direction to throw out the driveclutch. and, the camshaft and other parts are then brought to rest. in the proper position. by the engagement with the roller 136 of the stop-shoulder This invention is not limited'to the embodiment thereof hereinbefore described and. illustrated in the accompanying drawings.
