Definitions

  • An object of the invention is to provide improvements in the shoe-supporting means of that machine, and particularly in the shoe-supporting means shown in the lastmentioned Letters Patent, but it is to be understood that in various novel aspects the invention is not limited to the illustrative embodiment.
  • the machine is provided with a support for the heel end or cone of the last which is moved in a direction heightwise of the last by the pressure of the last thereon when the operator presents the work to the machine and which accordingly assumes in that respect a position determined by the heel end of the last, this cone support being movable also in directions widthwise of the last to different positions corresponding to the diiferent positions of the heel ends of differently shaped lasts when their toe ends are in proper relation to the lasting means.
  • An object of the present invention is to modify the above-described construction in such manner as to aiiord better insurance that the heel rest will be positioned in the most satisfactory relation to each shoe.
  • the heel rest instead of moving with the toe rest as above described, is so supported as to move in a direction heightwise of the last with the cone support when the latter is moved to a position determined by the heel end of the last in the presentation of the shoe and last to the machine, so that the position of the heel rest is similarly determined.
  • the construction shown is further such that the heel rest is movable in directions widthwise of the last with the cone support, so that it will assume a position corresponding to the lateral swing of the heel end of the last; and since the heel rest is located farther than the cone support from the junction of the angularly related longtiudinal median lines of the forepart and heel part of the last, novel means is provided for shortening any movement of the cone support in a direction widthwise of the last relatively to the movement of the heel rest in that direction.
  • the construction herein shown is further such that a device provided for applying the heel rest to the shoe does not partake of that movement but is so arranged that the heel rest and a carrier provided therefor move relatively to it.

J., a corporation of New. Jersey Application February 18, 1942, Serial No. 431,354 In Great Biritain March 11, 1941 30 Claims.
ters Patent No. 2,134,148, granted on October 25, Y
1938 on an application of mine, but modified in certain respects as further disclosed in other Letters Patent including Letters Patent No. 2,167,056 granted on July 25, 1939 on another application of mine. An object of the invention is to provide improvements in the shoe-supporting means of that machine, and particularly in the shoe-supporting means shown in the lastmentioned Letters Patent, but it is to be understood that in various novel aspects the invention is not limited to the illustrative embodiment.
In accordance with the disclosure of the abovementioned Letters Patent .No. 2,167,056, the toe end of the shoe on its last is clamped against a holddown in proper relation to the toe-lasting means by a toe rest which is moved heightwise of the shoe into clamping position by the operator prior to the starting of the power operation of the machine. Movable heightwise of the shoe with the toe rest, but at a greater speed than the toe rest, is a heel rest which after thus assuming a position opposite the heel end of the shoe is moved lengthwise of the shoe into engagement with its heel-end face. Additionally the machine is provided with a support for the heel end or cone of the last which is moved in a direction heightwise of the last by the pressure of the last thereon when the operator presents the work to the machine and which accordingly assumes in that respect a position determined by the heel end of the last, this cone support being movable also in directions widthwise of the last to different positions corresponding to the diiferent positions of the heel ends of differently shaped lasts when their toe ends are in proper relation to the lasting means.
An object of the present invention, among others, is to modify the above-described construction in such manner as to aiiord better insurance that the heel rest will be positioned in the most satisfactory relation to each shoe. To this end, in accordance with one feature of the invention, the heel rest, instead of moving with the toe rest as above described, is so supported as to move in a direction heightwise of the last with the cone support when the latter is moved to a position determined by the heel end of the last in the presentation of the shoe and last to the machine, so that the position of the heel rest is similarly determined. The construction shown is further such that the heel rest is movable in directions widthwise of the last with the cone support, so that it will assume a position corresponding to the lateral swing of the heel end of the last; and since the heel rest is located farther than the cone support from the junction of the angularly related longtiudinal median lines of the forepart and heel part of the last, novel means is provided for shortening any movement of the cone support in a direction widthwise of the last relatively to the movement of the heel rest in that direction.
To facilitate movement of the heel rest in a direction heightwise of the last to a position determined by the last as above described, the construction herein shown is further such that a device provided for applying the heel rest to the shoe does not partake of that movement but is so arranged that the heel rest and a carrier provided therefor move relatively to it. To insure, moreover, the most effective relation between this device and the heel rest in applying the heel rest to the shoe, provision is aiforded for moving the device heightwise of the shoe relatively to the heel rest and its carrier to a position substantially opposite the heel rest irrespective of the amount of movement imparted to the heel rest in the presentation of the last and shoe to the machine.
The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

The machine is provided with power-operated toe wipers 2 which are moved upwardly to wipe the toe-end portion of the upper heightwise of the last and are thereafter operated to wipe the marginal portion of the upper inwardly over an insole on the last. The position of the toe end of the shoe heightwise is determined by a holddown 4 against which the operator positions the bottom face of the toe end of the insole in presenting the shoe to the machine, and the posi-" tion of the shoe lengthwise is determined by a toe-end gage 6 arranged to engage the end face of the upper. The toe end of the shoe is clamped against the holddown 4 by a toe rest 8 mounted on a post I which is vertically movable in a jack casting I2 supported at its lower end on a shaft l4 and held normally stationary at all times. The post To is moved upwardly to clamp the shoe by a vertically movable bar l6 which supports it, this bar being moved upwardly through a lever l8 by a link 20 which is connected to a treadle (not shown). Thereafter the bar l6 and the post are controlled automatically in the power operation of the machine by pawls 22 in engagement with a ratchet wheel 24 formed integral with a pinion 26 which is rotatable on the shaft [4 and engages rack teeth 28 on th lower end portion of the bar. The pawls are pivotally mounted on a plate 30 which is rotatable on the shaft I4 and is connected by a rod 32 to mechanism including a spring 34 which acts through the plate and the pawls to hold the toe rest 8 pressed upward against the shoe but yields to permit a short downward movement of the toe rest with the shoe by the action of the holddown 4 just after the upward movement of the wipers. The pawls 22 are controlled by another plate 35 rotatable on the shaft l4 and are moved into engagement with the ratchet wheel 24 in response to movement of this plate in a counterclockwise direction (Fig. 1), the plate being moved in this manner by a spring 38 when permitted by a cam-controlled lever 40 which engages a lug 42 on the plate. The construction and operation of this pawland-ratchet mechanism are more fully disclosed in Letters Patent No. 2,134,148.
For supporting the heel end or cone of the last underneath the machine herein shown is provided with means constructed in many respects as disclosed in Letters Patent No. 2,167,056,- but differing therefrom in other respects. Located forwardly of the toe rest is a bar 44 which is hollow and the lower end portion of which is mounted on an upwardly extending stem portion 46 of a support 48, this support being pivotally mounted for swinging movements in directions lengthwise of the shoe on a pin 50 carried by a' sleeve 52. This sleeve is mounted for turning movement on a stud 54 which extends horizontally from a slide 56, so that the bar 44 may swing relatively to the slide in directions widthwise of the shoe. The slide 56 is mounted for vertical movements in a guideway provided in a downwardly extending portion 58 of a housing E8 fast on the jack casting !2. The upper end of the bar 44 has secured therein by a pin 62 a stem 64 extending downwardly from a block 66 which has formed therein, in rearwardly offset relation to the axis of the bar 44, three downwardly extending bores 88 in angular relation to one another. Mounted in one of these bores is the lower end portion of a last pin ID the upper end portion of which is arranged to extend into the usual spindle hole in the heel end of the last. Substantially midway between its ends the last ing a lower face 14 of spherical contour arranged to seat on a complementally formed face provided in the block 66. The enlargement 12 is also provided with an upper face 16 of frustoconical contour arranged to be engaged by the last at the outer end of its spindle hole and thus to serve as a direct support for the heel end or cone of the last. Since it is found in practice that the locations of the spindle holes often vary in different lasts, the last pin 10 may be mounted selectively in that one of the three bores 68 which is most appropriate for the particular last, to permit its toe-end portion to be positioned in the desired relation to the toe-lasting means. Preferably, moreover, as shown, that portion of the last pin which extends into the spindle hole in the last is of smaller diameter than the hole and is tapering to permit the last to be tipped in any direction relatively to the pin. It will be evident that in any position which it thus assumes the last is seated firmly on the frusto-conical face 16 of the enlargement 12.
A pair of light springs 18 (only one of which is shown) connected to the slide 56 and the housing 60 hold the slide normally at the upper limit of its movement along its guideway with the last pin 10 in a higher position in the machine than it occupies when the shoe is in position to be operated upon. Initially, moreover, the bar 44 which carries the last pin occupies a position in which it is tipped farther forwardly away from the toe rest 8 than when the shoe is in position to be operated upon. In presenting a shoe and last to the machine the operator mounts the last on the last pin 10 and through the last depresses the bar 44 and the slide 56 against the resistance of the springs 18, at the same time swinging the shoe and the bar 4-4 rearwardly to present the toe-end face of the shoe against the end gage 6 and the toe end of the insole against the holddown 4. It will thus be seen that when the toe end of the shoe is positioned at the correct height by the holddown with'its bottom face in proper relation to the plane of the wipers 2 the bar 44 is positioned at a height determined by the heelend portion of the last, whatever may be the size or shape of the last. In order that the heelend portion of the last will be thereafter adequately supported during the operation of the machine, mechanism similar to that disclosed in Letters Patent No. 2,167,056 is provided for looking the bar 44 against any further downward movement relatively to the toe rest. This mechanism includes a pair of vertically staggered horizontal pawls 88 slidingly movable in a bracket 82 (Fig. 1) on the bar [6, the pawls being movable by springs (not shown) into engagement with ratchet teeth 86 (Fig. 2) formed on the rear face of the slide 56. The pawls are normally held out of engagement with the ratchet teeth by a lever 88 mounted to swing on the bracket 82 and controlled by a pin 90 slidingly movable in the jack casting l2 and arranged to engage the lower end ofv the lever. This pin is, in turn, controlled by a push rod 92 mounted on the upper end of the previously mentioned lever 40. Accordingly, when this lever is swung in a clockwise direction to cause the pawls 22 to engage the ratchet wheel 24 it releases the pin 90 and thus permits the springs controlling the pawls to move them into engagement with the ratchet teeth 86.
The lower end of the tubular bar 44 rests on a shoulder on the support 48, and fast on the pin 10 is provided with an enlargement 12 hav- (6 lower end of the bar is a collar 94. Secured to the support. :48 is a clip-96 a portion of which is arranged'to bear against the upper face. of the collar 94 to prevent the bar 44-.'from moving upward relatively" to the support. Extending rearwardly from the collar 04 is a stem :98 .(Fig. 4.) having .a wall of convex contour in engagement with complementall-y shaped. walls of a bifurcated upper portion of an arm I pivotally mounted at its lower end on. the. slide 56 for swinging movements in directions lengthwise'of the shoe. The purpose of this construction will be hereinafter explained.
Pivotally mounted on a pin I02. on the support 48. for swinging movements in directions lengthwise. of the shoeis a block I04 having integral therewith an upwardly extending arm I06. At the opposite sides of the upper end of this aim there are secured, by bolts J08 upwardly extending bars I .I-0 between the upper ends. of which there is located a ring 2 having studs 4 (Fig. 3) by means of which the. ring is. pivotally mounted on the arms to swing about an axis extending widthwise of the shoe. Mounted to turn in the ring II2 about an axis extending length-wise of the shoe is a circular block IIB which has secured to its front face a downwardly extending plate II 8 provided with corrugations I on its front face. To the rear face of the block H6 is attached a headed stud I22 by means of which a heel rest I24 is secured to the block. The stud extends into a slot I26 (Fig. 3) in the heel rest, and upon turning movement of the latter to a position in which the head of the stud is in alinement with an enlarged end of the slot the heel rest may be detached from the block 6. The heel rest is held yieldingly in proper rela tion to the block by a spring-pressed detent I28 which is mounted in the block and is provided with a rounded end arranged to enter a corresponding recess in the heel rest. The heel rest is preferably formed of metal, and its rear face is suitably conc'aved, for engagement with the heel-end face of the shoe. It will be evident that upon engagement of the heel rest with the shoe it may swing with the block II6 about the axis of the studs II4 to adjust itself to the shoe. To prevent undue swinging movement of the block and the heel rest there are provided a leaf spring I30 and a coil spring I32 arranged to bear respectively against the front and rear faces of the plate H8. The leaf spring is secured to-the arm I06 and the coil spring is connected at its opposite ends to the bars IIO.
From the above description it will be evident that as an incident to the. presentation of .the
shoe and last to the machine the heel rest as .well as the support for the cone of the last assumes a position heightwise of the machine determined by the position of the heel end of the last, since both the cone support and the heel rest are fr'iovable downwardly as a unit against the resistance of the springs 18 by pressure of the last on the cone support. Insurance is thus afforded that when the heel rest is thereafter applied to the shoe it will occupy the correct position heightwise of the shoe. For thus applying the heel rest to the shoe the arm I06, which serves as a carrier for the heel rest, is movable about the pin I02 from the initial retracted position in which it is shown in Fig. 2 to the position in which it is shown in Fig. 1. For thus moving the arm there is provided a thrust member I34 arranged to bear on the front face of the plate IIB. This member is pivotally mounted for swinging movement about an axis extending widthwise of the shoe on the upper end of a slide I36 which is movable upwardly and downwardly along a guideway provided on a holder I38, this holder being mounted to swing lengthwise of the shoe about a pin I40 onv the housing 60. The slide I36 is connected by a pair of downwardly extending links I42, only one of which is shown, to the front ends of av corresponding pair of levers I544 which are pivotally mounted at their rear endson pins I46 supportedon the previously mentioned bracket. 82 which is movable upwardly and downwardly with the. toe rest. Substantially midway between their opposite ends the levers I44 are connected by links I48 to arms. I50, one of which is shown in Fig... 1 these arms being fast on the ends of a horizontal shaft I52 rotatable in the bracket 82.
East on the shaft I52. is a pinion I54 engaging a vertical rack I56 secured to the jack casting I2. Accordingly, when the toe rest is moved upwardly as hereinbefore described to clamp the shoe the shaft I52 is rotated. by the action of the stationary rack I56 on the pinion I54, so that the arms I50 are swung upwardly and act through the links M8 to impart upward swinging movements to the levers I46 while these levers are at the same time being moved bodily upward with the toe rest. Accelerated movement is thus imparted to the slide I36 to move the thrust member I34 heightwise of the shoe to a position opposite the heel rest I24. This movement of the thrust member is limited by its engagement with a lug I58 on the plate H8, so that regardless of the amount of downward movement im-.
parted to the heel rest in the presentation of the shoe to the machine the thrust member is positioned invariably opposite the heel rest in applying it to the shoe. To permit further upward movement of the links I48 after the movement of the thrust member I34 is stopped by the lug I58, there are mounted in the links springs I60 which bear at their upper ends against pins I62 in the levers I44, these pins extending into slots I64 in the links to permit upward movement of the links against the resistance of the springs. Formed F on the rear face of the thrust member I34 are corrugations I66 arranged to interlock with the corrugations I20 on the front face of the plate II8 when the thrust member is in its uppermost position to prevent the heel rest from moving widthwise of the shoe. relatively to the slide I36.
For locking the slide I36 against downward movement after the thrust member I34 has been moved. upwardly to the position determined by the lug I 58, there is secured to the slide a toothed plate I 68 arranged to be. engaged by teeth formed on the rear end of a finger I10 which is connected to one arm of a bell-crank lever I12 pivoted at I14 to the holder I38. A springpressed member I10 mounted in the bell-crank lever I12 is arranged to bear against a lug on the holder I38 and thus tends to swing the lever in the direction to move the finger I10 into engagement with the teeth of the plate I68. The rear end of a rearwardly extending arm of the bellcrank lever I12, however, is arranged to be encaged underneath by the front end of a forwardly extending arm of another bell-crank lever I10 to hold the finger I10 normally out of contact with the plate I68. The bell-crank lever I18 is pivoted at I on the frame of the machine and has a downwardly extending arm pivotally connected to the front end of a bar I82 (Fig. 1) This bar extends rearwardly and has in its rear end a slot I84 into which extends a pin I86 mounted in the upper end of the previously mentioned lever 40. Accordingly, when this lever is swung in a clockwise direction (Fig. 1) to cause the pawls 22 to control the toe rest, the bell-crank lever H8 is swung in the direction to release the bell-crank lever I'I2, thus permitting this lever to be swung by the spring-pressed member I16 in the direction to move the finger I10 into locking engagement with the teeth of the plate I68.
The slide I36 and its holder I38 are swung about the pin I40 to cause the thrust member I34 to swing the arm I06 in the direction to apply the heel rest to the shoe by mechanism constructed mainly like that disclosed in Letters Patent No. 2,167,056 for imparting a corresponding movement to the heel rest therein shown. This mechanism includes a pair of chains I88, only one of which is shown, to which operative movement is imparted by a spring (not herein shown) when the spring is released near the end of the upward movement of the toe rest. As herein illustrated, these chains are connected to bars I90 which through links I92 are connected to the upper end of the slide I36.
. Reference has been made to the fact that the support for the cone of the last may swing in directions widthwise of the last about the stud 54. This permits the cone support to be positioned widthwise of the machine as required by the lateral swing of the heel endof a right or a left last in the presentation of the last and shoe to the machine. Since the heel rest I24 and its carrier arm I06 are supported by the member 48 which thus swings with the cone support about the stud 54, it will be evident that the heel rest likewise receives a swinging movement widthwise of the machine to position it in proper relation to the heel end of a right or a left shoe. Since the heel rest, when engaging the shoe, is located farther than the last pin I from the junction of the angularly related longitudinal median lines of the forepart and heel part of the shoe, it will be further evident that in any positioning movement of the heel rest and the cone support in a direction widthwise of the shoe the heel rest should move farther in that direction than the cone support. This is illustrated in Fig. 5, in which ab represents the longitudinal median line of the iorepart, bc represents the longitudinal median line of the heel part and 01 represents the location of the spindle hole in the last. It is in view of these conditions that the collar 94, which is fast on the lower end of the bar 44, is provided, as hereinbefore described, with the stem 98 engaged on its opposite sides by the walls of the' bifurcated arm I00. By reason of this construo tion the bar 44, in any swinging movement in a directionwidthwise of the shoe about the stud 54; is also forced to turn about the stem 46 and thus to impart to the offset last pin I0 which supports the heel end of the last a comparatively short swinging movement in the oppoiste direction about the axis of the bar. This shortens the movement of the last pin widthwise of the shoe relatively to the movement of the heel rest in that direction, and affords further insurance that the heel rest will be positioned widthwise of each shoe in proper relation to the heel end of the shoe. When there is no shoe in the machine swinging movement of the cone support and the heel rest widthwise of the machine is limited by engagement of a downwardly extending portion of the sleeve 52 with one or the other of two forwardly extending flanges I94 formed on theportion 58 of the housing 60. a
In the use ofthe machine, in so far as it is of interest with reference to the present invention, the operator mounts a last and shoe on the cone support with the upper end of the last pin 10 extending into the spindle hole in the last, and through the last swings the cone support rearwardly to present the toe end of the shoe under the holddown 4 and against the end gage 6, at the same time pressing downwardly on the heel end of the shoe and last to lower the cone support and the heel rest and to cause them to assume heightwise of the machine positions determined by the position of the heel end of the last when the toe end of the shoe is in proper relation to the holddown and the toe wipers. The operator may also swing the heel end of the shoe laterally in one direction or the other to position its toe end in proper relation to the wipers, and by such swinging movement of the heel end of the shoe the cone support and the heel rest are swung laterally to the proper corresponding positions, the heel rest moving farther than the cone support as hereinbefore explained. Thereafter the operator, by depressing the usual treadle, moves the toe rest 8 and its support upwardly to clamp the toe end of the shoe against the holddown 4. By the upward movement of the toe rest support the thrust member I34 and its supporting slide I36 are moved upwardly along the arm I06 until the thrust member arrives in a position opposite the heel rest I24 and engages the stop lug I56. Near the end of the upward movement of the toe rest the spring which operates the chains I88 is released and acts through the chains to swin the thrust member I34 and its slide I36, together with the holder I38, about the pin I40, thereby operating the arm I06 to swing the heel rest into engagement with the-heel end of the shoe. After the shoe has thus been engaged by the heel rest and the heel rest has been locked against reverse forward movement in the manner disclosed in Letters Patent No. 2,167,056, the operator starts the power operation of the machine, whereupon the lever 40 is swung in a clockwise direction (Fig. 1) to cause the pawls 22 to be moved'into positions to control the toe rest, to cause the cone support and the heel rest to be locked by the pawls against downward movementrelatively to the toe rest and to cause the slide I36 to be locked by engagement of the finger I10 with the teeth of the plate I68, as hereinbefore described in detail. Near the end of the cycle of operations, in response to reverse swinging movement of the lever 40, the pawls 22 are moved into positions to release the toe rest and its support for downward movement, the slide I36 is released by the finger I10 to permit it to be moved downwardly in response to downward movement of the toe rest support, and the slide 56 supporting the heel rest and the cone support is released by the pawls 80. The heel rest also is unlocked by the mechanism which holds it against forward swinging movement, permitting the operator to swing it forwardly and thereby to tension the spring which operates the chains I88 in the same general manner as disclosed in the last-mentioned Letters Patent.
