54 Claims.

This invention relates to shoe machines, and is herein illustrated as applied to a toe-end lasting machine of the same general character as disclosed in United States Letters Patent No. 2,160,846, granted on June 6, 1939, on an application of mine and A. F. Pyms. It is an object of the invention to provide improvements in a machine of that character, but it will be recognized that in various novel aspects the invention is not thus limited in its applicability.

As one of its features, the invention provides novel means whereby a shoe-positioning device engaging the bottom of the shoe is moved with the shoe if the latter receives any heightwise movement in the lasting operation from the pressure of the lasting means on the bottom thereof. In the construction shown a shoe-positioning plate which engages the toe end of a welt shoe insole and supports its lip against the inwardly directed pressure of the lasting wipers is thus moved by a springto maintain it in proper supporting relation to the lip if the shoe is moved heightwise by the pressure of the wipers thereon.

This spring, as illustrated, acts in opposition to a spring through which the shoe is forced, as heretofore, against the plate and which is yieldable to permit heightwise movement of the shoe by the wipers, and it therefore facilitates such movement of the shoe by the wipers to assist in avoiding any danger of damage to the upper in the wiping'operation.

In one form herein shown the machine is provided not only with a device for engaging and supporting the lip of the insole as above described, but also with a plurality of pins arranged to extend through holes in the insole into holes in the last to assist in positioning the shoe and in maintaining it in a fixed position lengthwise and laterally. To aid the operator in presenting the shoe in proper relation to the lip-engaging device, the invention further provides means whereby this device is positioned initially in such relation to the pins as to permit the shoe to be presented in engagement with it before the shoe is mounted on the pins, after which the device is moved relatively to the pins by pressure of the shoe thereon to permit the pins to enter the holes in the insole and last.

To assist in controlling the shoe, especially if the above-mentioned pins are not used, the machine includes, as heretofore, a flexible heel band arranged to embrace the heel end of the shoe and controlled by arms which swing laterally of the shoe to permit the band to adjust itself to the position of the heel end of the shoe. To

afford better insurance against any lateral displacement of the heel end of a right or a left shoe by the increased pressure of the band thereon after it has adjusted itself to the shoe, mechanism is provided, in accordance with a further feature of the invention, for locking the bandcontrolling arms against further swinging movements after the band has assumed the position determined by the shoe. As illustrated, such locking of the arms occurs in response tothe pressure of the shoe against the band. Novel means also is provided for adjusting the band in directions lengthwise of the shoe.

In combination with a shoe rest for engaging the top of the forepart of the shoe as heretofore, the invention further provides novel means for controlling the heel end of the shoe to afford better insurance against any tipping of the shoe in the. lasting operation. The construction shown comprises a heel-end support which is swung upwardly into supporting relation to the heel end of the shoe as the above-mentioned shoe rest is applied to the shoe, and mechanism for locking the heel-end support in operative position in response to pressure of the shoe on the shoe rest.

The machine shown in the previously mentioned Letters Patent is provided with means for pulling the toe end of the upper over the last in the toe-lasting operation, comprising grippers which grip and pull the upper respectively at the end and the sides of the toe. The jaws of the side grippers are arranged to present between them upper-receiving openings which extend generally heightvvise of the last, in View of the upstanding condition of the margin of the upper at the sides of the toe, while the jaws of the toe-end gripper present an upper-receiving opening extending generally lengthwise of the last, in view of the forwardly flaring condition of the upper at the end of the toe when the work is presented to the machine. The present invention, as one of its features, provides a construction in which that jaw of the toe-end gripper which engages the outer face of the upper is positioned initially farther from the other jaw than heretofore to facilitate the presentation of the upper in proper relation to the gripper, the construction being also such that both the jaws receive upper-gripping or closing movements heightwise of the shoe instead of only the jaw which engages the inner face of the upper as in the prior construction, thus avoiding any danger that the upper will .be objectionably displaced heightwise of the last relatively to, the

side grippers by the closing of the toe-end gripper. As illustrated, the jaws of the toe-end gripper are closed through a novel arrangement of toggles connected respectively to the different jaws, the jaw which engages the outer face of the upper being moved into upper-gripping position and locked in that position by its toggle before the upper is gripped against it by the movement of the other jaw. It will be evident that in one aspect the invention thus provides a novel gripper for gripping and pulling an upper over a last, irrespective of the relation of the gripper to other parts.

In accordance with another feature, the invention provides novel wiper-operating and controlling means, comprising a comparatively light spring arranged to press the wipers yieldingly against the upper opposite the end face of the last in the wiping of the upper heightwise of the last, combined with a heavier spring which is yieldable thereafter as heretofore in response to resistance of the upper to bodily movement of the wipers lengthwise of the last in pressing the upper against the lip of the insole. This insures that the upper will be wiped effectively heightwise of the last at the end of the toe without the necessity for a precise preliminary adjustment of the wipers lengthwise of the last.

In still another aspect, the invention provides a novel gripper adapted for use to pull an upper at the side of the toe, although not restricted to that particular use, an object being to insure that the pulling of a portion of the upper which is comparatively loose on the last will not be ohjectionably restricted by the resistance of another portion which is less yieldable by reason of its proximity to a portion already pulled and fastened. For the purpose in view, the construction herein shown comprises two pairs of uppergripping jaws for pulling an upper respectively near the end of the toe and farther from the end of the toe, and novel means whereby the pair which pulls the upper farther from the end of the toe is yieldingly controlled independently of the other pair to permit the latter to receive a movement of greater extent in the upperpulling operation.

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.

In view of the disclosure in the previously mentioned Letters Patent, such parts of the machine organization as are common to that disclosure will be hereinafter described only in so far as is necessary for an understanding of the features of the present invention. The machine is provided, in general, with a toe-end gripper 2 for gripping the margin of the upper at the end of the toe and with opposite side grippers 4 for gripping it at the sides of the toe, and is further provided with wipers 6 which wipe the upper around the toe end of the last heightwise of the last and thereafter wipe its marginal portion inwardly over an insole on the last and press it against a welt-attaching lip on the insole. In time relation to the movements of the wipers the several grippers pull the upper heightwise of the last and receive movements also to spread the upper outwardly over the edges of the wipers. After the wipers have wiped the upper inwardly against the lip of the insole the machine comes to a stop to permit the operator to attach the end of a binder wire to a tack at one side of the shoe bottom and to pull the wire around the toe under the wipers. When the machine is next started, the operator pulls the wire tightly inwand against the upstanding margin of the upper, as permitted by the wipers, the latter then forcing the wire more firmly against the upper. The machine then comes again to a stop to permit the wire to be fastened to a tack at the other side of the shoe. The machine thereafter completes its cycle, the parts returning to their starting positions.

The position of each shoe and its last (sometimes herein referred to inclusively as the shoe) is accurately determined, as heretofore, in the construction shown in Figs. 1 and 3, by an insoleengaging plate 8 provided with a downwardly extending rim "3 formed substantially to fit the inner face of the lip of the insole around the toe and to support the lip against the inwardly directed pressure of the wipers. The plate 8 is detachably secured on the lower enlarged end of a rod I2 mounted in a frame casting M on the top of the main frame Id of the machine. The

shoe is supported in the position determined by the plate 8 by a toe rest I8 which in the construction herein shown is itself supported as hereinafter described on the upper end of a vertically movable rod 26. This rod is moved upwardly to cause the toe rest to clamp the shoe against the plate 8 by mechanism constructed substantially as described in Letters Patent No. 2,224,146, granted on December 10, 1940, on an application of mine, this mechanism including a comparatively light spring 22 (corresponding to the spring 86 therein shown) against the resistance of which the shoe and the toe rest are yieldable in a downward direction in response to pressure of the wipers on the upper as they wipe its marginal portion inwardly over the insole, thus avoiding any danger of damage to the upper by the wipers. The present invention provides a construction in which any such downward movement of the toe end of the shoe is accompanied by downward movement of the insole-engaging plate 8, so that the plate is maintained in position to support the lip of the insole throughout the height of the lip. For this purpose, the rod E2 is vertically movable in the casting it against the resistance of a light spring 25 (Fig. 2) in response to the upwardly directed pressure of the toe rest in clamping the shoe against the plate 8, and the spring 24 thereafter moves the rod and the plate downwardly with the shoe if the shoe is depressed by the wipers. It will be understood that the spring 24 is lighter than the spring 22 through which the toe rest is controlled. The upward movement of the rod I2 is limited by engagement of a shoulder 29 thereon with the lower end of a nipple 28 which is threaded in the casting l4 and has a bore into which a reduced portion 33 of the rod extends. A further reduced portion 32 of the rod is threaded in a sleeve 34 provided with a flange 36 which normally rests on the nipple 28 and serves as an abutment for the lower end of the spring 24. At its upper end the spring 23 abuts against a member 38 having a conical portion seated in a recess formed in a cap 50 which is threaded in the nipple 23 and is held fast therein by a lock nut 42. It will be understood that the nipple 28 may be turned to adjust the rod l2 and the plate 8 in directions heightwise of the shoe without altering the distance between the shoulder 26 on the rod and the lower end of the nipple. To vary this distance, and accordingly to vary the amount of upward movement which the plate 8 receives when the shoe is clamped against it, the sleeve 34 may be turned on the reduced end 32 of the rod l2. A set screw 34 threaded in the sleeve and engaging the reduced end of the rod serves to lock the sleeve in adjusted position.

In addition to maintaining the plate 8 in proper relation to the lip of the insole if the shoe is depressed by the wipers, the spring 2 1 serves to render the shoe more readily depressible, since it acts in opposition to the spring 22. It will be evident, however, that the spring 24 does not subtract from the force with which the shoe is held against the plate 3 by the spring 22 prior to the wiping of the upper inwardly over the insole by the wipers. There is, accordingly, no danger that the shoe will not be held against the plate with sufficient force to control it properly during the upper-pulling operation and the wiping of the upper heightwise of the toe, notwithstanding the fact that the shoe is thereafter more readily depressible by the wipers than heretofore. After the wipers have wiped the upper inwardly over the insole the shoe is forced more firmly up against them by the toe rest through the action of mechanism disclosed in the last-mentioned Letters Patent, this mechanism comprising springs 46 and i8 arranged for selective use and stronger than the spring 22.

In combination with the toe rest it, the machine herein shown is provided with a heel-end support arranged to engage the lastunder its heelend portion to afiord better insurance against any tipping of the shoe and last by the action of the lasting meansthereon. Fast on a reduced upper end of the previously mentioned rod 20 is a block 50 (Figs. 9 and 10) provided on its two opposite sides with studs 52 which serve as fulcrums for two levers 54 in locations substantially midway between the opposite ends of the levers. These levers extend lengthwise of the shoe and their forwardly extending arms carry a pair of L-shaped rods 56 which are held in sockets in the levers by thumb screws 53. Mounted on portions of the rods 56 which are in alinement with each other is a rubber tube 50 arranged to engage the top face of the heel-end portion of the inverted last when the levers 56 are swung upwardly from their initial positions. The rearw ardly extending arms of the levers E i are connected at their rear ends in fixed relation to each other and to a member 82 between them by two bolts 6 3. Initially the levers are maintained by gravity in the positions illustrated in Figs. 3 and 9. When the rod 20 is moved upwardly to carry the toe rest [8 into engagement with the shoe and to clamp the shoe against the plate 8, a spring 66 which is connected at its lower end to the frame of the machine and at its upper end to an arm 58 (Fig. 10) fast on one of the levers 54 acts in response to the upward movement of the rod to swing the levers 54 as a unit in the direction to lift the tube 6% and thus carry the tube into engagement with the heel-end portion of the last near the end of the upward movement of the rod. The spring 68 is a light spring the force of which is not suflicient to disturb the position of the shoe as the operator holds it in engagement with the plate 3 ready to be clamped by the toe rest l8.

To render the heel-end support effective to support the shoe thereafter in the required manner, mechanism is further provided for looking it in the position which it has thus assumed. For this purpose there is movably mounted on the block 50, between this block and the member 62, a brake shoe 70 arranged for frictional engagement with an arcuate face 72 on the member 62 the curve of which is concentric with the studs 52. The brake shoe "it is provided at its lower end with a lip M which lies in a groove in the block 50 to support the brake shoe while permitting it to be swung to the right, as the parts are viewed in Fig. 9, to press frictionally on the armate face 72. The brake shoe has at its opposite sides upwardly extending arms 76 having therein depressions to receive the rear ends of rods 78. The front ends of these rods lie in depressions formed in ears 80 on hubs of rearwardly extending arms 82 which are pivotally mounted on the studs 52 between the block 50 and the levers 54. The rear ends of these arms carry a pin 84 which is movable upwardly and downwardly in a slot 86 in the block 50 and extends through the head 88 of a screw 90 threaded in a depending portion of a U-shaped holder 92 on which the toe rest i8 is supported. Provision is afforded for limited movement of the holder,92 in upward and downward directions relatively to the block 50, the holder being guided partly by engagement of this block with the depending portion of the holder in which the screw 80 is mounted and partly by engagement of the block with a stud 9&- fast on the holder and mounted in a recess in the block above the upper end of the rod 20. A spring as engaging the block and the holder tends to lift the holder and maintains it initially in a position determined by engagement of the pin 8% with the block 563 at the upper end of the slot 86. When the upward movement of the toe rest 28 is stopped by the shoe, further upward movement ofthe rod 213 causes the block 50 to move relatively to the holder 52, and since the pin 84 is controlled by the holder such further upward movement of the block 59 causes the arms 82 to swing in clockwise directions, as the parts are viewed in Fig 9, to impart rearward movements to the rods 78 and thus to force the brake shoe it into eifective frictional engagement with the member 52. The levers 5t and their rods 56 are accordingly locked in shoesupporting positions. The toe rest is itself is constructed substantially as disclosed in Letters Patent No, 2,224,146 and it is clamped to the upwardly extending arms of the U-shaped holder 92 by a bolt t8 extending through slots Hill in the arms, these slots permitting adjustment of the toe rest in directions lengthwise of the shoe.

The machine herein shown is provided as heretofore with a flexible heel band m2 arranged to embrace the heel end of he shoe and to assist in preventing lengthwise forward displacement of the shoe in the toe-lasting operation. The band I02 is supported at its opposite ends, as described in detail in Letters Patent No. 2,160,8 i6, on arms 104 which are mounted for swinging movements in directions laterally of the shoe on horizontal rods I96 rearwardly movable in bearings in the frame to apply the heel band to the shoe. The two rods HIE are connected together by a yoke 38 (Fig. 4), and they are operated through a link H!) which connects one of them to an arm M2 on a rock shaft lit. A pin M6 on this rock shaft acts on the hub of the arm l 52 to swing the arm in the direction to apply the heel band to the shoe when the rock shaft is turned at a predetermined time in the operation of the machine by a spring H8 connected to an arm 22% on the shaft, as fully disclosed in the last-mentioned Letters Patent. After the heel band has been applied to the shoe by the spring l .18, it is forced more firmly against the shoe and held against retractive movement by a pawl 522 (Fig. 3) which is arranged .to engage teeth ii t on the yoke E38 and is operated by a spring 12, as also disclosed in the last-mentioned Letters Patent. Mounted as heretofore. between the hubs of the arms H34 and caps l23 fast on the ends of the rods I96 are helical springs E39 which tend to swing the arms away from each other and are yieldable to permit the arms to approach each other so that the heel band may wrap itself about the heel end of the shoe. It will be understood that the provision for swinging movements of the arms H241 further permits the heel band to assume diiferent positions corresponding to the different positions widthwise of the machine of the heel ends of right and left shoes the positions of the toe ends of which are determined by the plate 8 as hereinbefore explained. To afford better insurance against any lateral displacement of the heel end of a shoe by the force of the heel band when it is pressed firmly against the shoe after having adjusted itself thereto, the present invention provides locking means arranged to act on the arms Hi4. For the purpose in view there is inserted in a recess in the hub of each arm a plate I32 having thereon teeth I34 arranged to engage cooperating teeth 36 formed on the cap I28. There is provision for limited movement of each arm lied in directions lengthwise of its supporting rod W6 between the cap I28 and a collar H38 on the rod, so that the arm may swing as required to permit the heel band to adjust itself to the shoe before the arm is locked by the teeth. While the teeth I34 and H6 are so formed as not to prevent the required swinging movements of the arms lt i until the heel band has been applied to the shoe with a substantial amount of force, the helical springs 1130 are preferably so formed that they not only tend to swing the arms 5% away from each other, but also tend to move the arms toward the collars 33, the springs yielding to permit the effective locking of the arms by the teeth when substantial pressure is applied by the heel band. to the shoe. In the construction herein shown, moreover, each of the two rods Hi6 comprises telescopic parts Hit and M2 to permit preliminary adjustment of the heel band in directions lengthwise of the shoe for shoes of different sizes. Each part M2 extends into the part Hit) and is provided with three recesses M4 to receive selectively a spring-pressed plunger Hi6 carried by the part Hill. A stud Hill threaded in the part Hi2 extends into a slot I50 in the part hill to limit relative movement of the parts.

In Fig. '1 is shown alternative shoe-positioning means which may be used instead of the shoe-positioning means shown in Figs. 1 and 3. comprises a plate 552 similar to the plate 8 of Figs. 1 and 3 and against which the shoe is clamped by the toe rest 53, this plate being formed to fit the inner face of the lip of the insole around the toe and to support the lip against the inwardly directed pressure of the wipers. In addition to the plate, there are provided three pins i554, only two of which are visible in Fig. 7, arranged to extend through holes in the insole into holes in the forepart of the last to assist in positioning the shoe and in maintaining it in a fixed position lengthwise and laterally. Enlarged portions of the pins i5 l are scoured to the lower enlarged end of the rod i2 and extend through openings in the plate 52 and in a holder which carries the plate. Slidingly mounted in the holder Edd is a retaining member 458 which extends downwardly through a slot 3% in the plate and locks the plate up against the holder. This member may be moved against the resistance of a spring i62 by means of a knob EM to release the plate and permit another to be substituted. The holder and the plate lt l are movable as a unit heightwise of the shoe relatively to the pins i54 and a spring 5% mounted in an upwardly extending portion ltd of the holder tends to move it and the plate in a downward direction, the downward movement thereof being limited by a stud Fit the reduced end of which extends into a slot H2 in the portion E33. Initially the plate E52 is held by the spring in a position in which its lower edge is approximately at the same level at the lower ends of the pins 154, so that when the operator presents the shoe to the machine he may readily position the shoe with the lip of the insole in proper engagement with the plate before the shoe is mounted on the pins. Having thus presented the shoe, the operator lifts it with the plate against the resistance of the spring I65 to cause the pins 15a to enter the holes in the insole and last.

As in the machine shown in Letters Patent No. 2,160,846, the jaws of the side grippers 4 present openings between them which extend generally heightwise of the last to receive the upstanding marginal portion of the upper at the sides of the toe, while the jaws of the toe-end gripper 2 present an upper-receiving opening extending generally lengthwise of the last in view of the forwardly flaring condition of the upper at the end of the toe when the work is presented to the machine. For purposes of the present invention the toe-end gripper is so constructed that its lowerjaw extends downward at a greater inclination than heretofore to present a wider opening between the jaws and thus to facilitate the presentation of the upper in proper relation to the gripper, and the construction i further such that both the jaws receive gripping or closing movements instead of the upper jaw alone as heretofore, so that notwithstanding the lower position of the lower jaw there is no danger of objectionable displacement of the upper in a downward direction relatively to the side grippers in the closing of the toe-end gripper on the upper. As illustrated in Fig. 5, the gripper comprises, as heretofore,

a casing I'M by upward movement of which the pulling of the upper is effected, and a rod 176 which is moved upward relatively to the casing by a spring 118 in the casing to close the gripper on the upper when permitted by the lifting of a member I 86 which engages a plunger I82 on the rod and normally holds the rod depressed with the jaws of the gripper in open relation. The gripper includes an upper jaw !84 mounted to swing about a pin H36 in the casing H4, and a lower jaw 88 which in the construction shown is also mounted to swing about the pin I236. The jaw-closing rod H6 is connected by a link I90 to one end of a curved lever I92 which acts as a bell-crank lever and is pivotally mounted substantially midway between its opposite ends on a pin 594 in the casing I74. The other end or arm of the lever I 92 is connected by a link 1% to an arm E98 f the jaw i841, and another portion of the same arm of the lever 592 is also connected by a link 2% to the jaw I88. Pins 292 and 294 connect the opposite ends of this link respectively to the lever I92 and the jaw HES. By reference to Figs. 5 and 6 it will be evident that the link I96 and the arm of the lever M2 to which it is connected serve as a toggle to effect the closing movement of the jaw i5 3, and that the link 20! and the portion of the same arm of the lever I92 to which it is connected serve as a toggle to effect the closing movement of the jaw I88. The relation of the several parts is such that the jaw I8 3 receives initially a comparatively rapid upward closing movement and comes substantially to a stop by reason of the straightening of its operating toggle before the upper jaw 434 has been swung downwardly far enough to grip the upper against it. Under ordinary conditions, as illustrated in Fig. 6, the toggle for operating the jaw H38 is, in fact, swung slightly past a straightened condition when the jaws are closed, a will be evident from the positions of the pins 294, 2252 and 286, the toggle for operating the jaw E8 being still only partially straightened. This means for operating and controlling the jaws not only insures that the toe end of the upper will not be objectionably displaced in a downward direction in the closing of the jaws, but also insures that the lower jaw will be positively locked against any tendency for it to be swung reversely in a downward direction by the strain of the upper thereon inthe upper-pulling operation.

The wipers 6 are supported on a wiper carrier 206 (Fig. 3) and are swung toward and from each other laterally of the shoe by means constructed as disclosed in Letters Patent No. 2,160,846. As also therein disclosed, the wiper carrier 2% is pivotally supported near its front end on the upper ends of two links 2t8, only one of which is visible in the drawings, these links being pivotally connected at their lower ends to arms 2H1, only one of which also is Visible, fast on a rock shaft 2H2 which is turned by means of a cam-operated lever 2M to impart upward and downward swinging movements to the wipers. The wiper carrier 206 is pivotally connected at its rear end, as fully disclosed in the above-mentioned Letters Patent, to the upper end of a lever 2l6 moimted to swing about a fulcrum rod 2l8 and operated by a path cam 220 to move the wiper carrier and wipers lengthwise of the shoe, the links 208 in this operation swinging about their connections to the arms 2H]. The fulcrum rod 2"! is supported on an upwardly extending lever 222 fulcrumed at its lower end at 224 on theframe of the machine and controlled at its upper end through a rod 226 by one or the other or both of two springs 228, 230 against the resistance of which the rod 225 is yieldable in a rearward direction in response to resistance of the upper to the movement of the wipers lengthwise of the shoe. That is, when the wipers are forced against the upper with a predetermined pressure by the lever M6 the fulcrum rod M8 on which this lever is mounted yields in a rearward direction in response to any further tendency of the cam 22!! to swing the lever 2H5 in the direction to advance the wipers. For a further understanding of the manner of operation of these parts the above-mentioned Letters Patent may be consulted.

The construction herein shown includes, in addition to the springs 228, 230, a lighter spring 232 arranged also to control the lever 222 and yieldable to permit-movement of this lever and its fulcrum rod H8 in response to resistance of the upper to the pressure of the wipers thereon in the wiping of the upper heightwise of the last, the springs 228, 236 being effective to determine the pressure applied by the wipers to the upper only at the end of the overwiping movement of the wipers when the upstanding margin of the upper is forced against the lip of the insole. The spring 232 abuts at its front end against a trunnion block 234 pivotally supported on the upper end of the lever 222 in a bifurcated portion of the lever, and abuts at its rear end against a thimble 235 which is threaded on the rod 226 and is confined on the rod by the head of a screw 238 threaded in the end of the rod. The trunnion block 234 is slidingly movable along a sleeve 240 which is adjustablyrthreaded on the rod 226 and has a head 2M normally engaging the front face of the block, and its movement relatively to the sleeve in a rearward direction is limited by its engagement with a washer 242 which is clamped against the end of the sleeve 24!) by a nut 244. The thimble 236 is held from turning by means of a rod 246 which is fast at its front end in the trunnion block 234 and extendsinto a slot 248 in the thimble. It will thus be seen that in response to resistance of the end face of the upper to the pressure of the wipers thereon in the wiping of the upper heightwise of the last the lever 222 is yieldable in a rearward direction relatively to the rod 226 against the resistance of the spring At the end of the overwiping operation of the wipers the light spring 232 yields before either of the heavier springs 228, 230 until the trunnion block 234 engages the washer 252, after which further resistance of the upper causes the rod 225 to yield against the resistance of one or the other or both of the heavier springs.

In the construction shown in Letters Patent No. 2,160,846 turning movement of the rod corresponding to the rod 226 was utilized to effect an adjustment of the lever 222 and thereby to adjust the wipers preliminarily lengthwise of the shoe. By reason of the provision of the addi tional spring 232, which affords substantial leeway for yield of the wipers in the upwiping op eration, such adjustment of the wipers is ordinarily unnecessary, except as a setting-up ad justment which is effected by turning the sleeve 240 after loosening of the nut 244. The rod 226,

however, may still be turned as heretofore by means of a hand wheel 25!! at the front of the machine, and such turning 'of the rod is effective to vary the amount of compression of the spring 232 by moving the thimble 236 along the rod, the thimble being prevented from turning as above described by means of the rod 246, It will be understood that as the rod 225 is thus turned, the sleeve 24$] turns with it in its bearing in the trunnion block 234. In this manner the amount of pressure applied by the wipers to the end face of the upper in the wiping of the upper heightwise of the last may be readily varied.

In Figs. 12 to 15, inclusive, is shown one of two opposite side grippers which may be used instead of the previously mentioned side grippers 4 for pulling the upper at the Sides of the toe. Instead of a single pair of upper-gripping jaws, this alternative gripper comprises two pairs of jaws 252 and 254 arranged respectively to grip and pull the upper in a location comparatively near the tip line, if the upper is provided with a tip, and in a location nearer the end of the toe. In view of the fact that near the tip line,

and accordingly near portions of the upper which have already been pulled and fastened prior to the operation of the illustrated machine, the upper is less yield-able than in locations nearer the end of the toe, provision is afforded in the construction shown for relative movement heightwise of the last of the difierent pairs of gripper jaws, as more particularly hereinafter described, The gripper further comprises a casing 255 common to both pair of jaws and through upward movement of which the jaws are operated to pull the upper, the casing serving as a carrier for the jaws. Such upward movement is imparted to the casing by mechanism of the same character as disclosed in Letters Patent No. 2,160,846, comprising a yoke member 258 which in the construction herein shown is secured to a tubular member 259 fastened at its lower end to a boss on the casing 256 and serving as part of the jaw carrier.

Mounted between a portion of the casing 256 and a cover plate 2%2 fastened to the casing by two screws 2% and a third screw 266 are two slides 268 and 216 which serve respectively as holders for the pairs of jaws 252 and 254. Formed in the casin 255 (Fig. 15) is a groove into which extend tongues 2'i2 on the slides 258 and 21 to maintain the slides in contiguous relation to each other while permitting them to move relatively to the casing in directions heightwise of the shoe. A spring 214 connected to a pin 216 on the casing 255 and to a pin 218 on the slide 21!] holds this slide normally in a'position determined by engagement of its upper end with a shoulder 28!! (Fig. 12) on the casing. The other slide 268 is controlled by a spring 282 which is mounted in a bore formed in a laterally extending portion of the slide and engages the slide at the upper end of the bore. The lower end of the spring 282 is in engagement with a shoulder formed on a screw 2% a reduced portion of which extends upwardly through the spring and is threaded in a lug 285 on the casing 256. It will thus be seen that the spring 282 tends to move the slide 268 upward relatively to the casing 256. The normal position of the slide is determined by nuts 288 which are threaded onthe screw 284 and one of which is engaged by the lateral extension of the slide, as shown in Fig. 12. Since the screw 284 is carried by the casing 256, it will be evident that the normal position of the slide 268 as well as that of the slide 210 is determined by the casing. The slide 21%] is longer than the slide 268 heightwise of the shoe, and, accordingly, the pair of jaws 252 at the lower end thereof extend downwardly farther toward the upper than the pair of jaws 252 at the lower end of the slide 268, as illustrated in Fig. 12. This is advantageous by reason of the fact that when a shoe is presented to the machine for the lasting operation the portion of the margin of the upper engaged by the jaws 254 ordinarily does not extend so far upwardly as the portion of the margin engaged by the jaws 252.

Each pair of jaws 252 and 254 comprises a jaw 290 which is fast on the slide 253 or 218 and a jaw 292 mounted to swing about a pin 29 on the slide toward and from the jaw 2s. Slidingly mounted on each of the jaw-carrying slides 268 and 210 is a jaw-closing slide 296 which carries two rolls 2% and 399 located respectively at opposite sides of a tail portion 392 of the jaw 292. Accordingly, this jaw is moved into upper-gripping relation to the jaw 290 by upward movement of the slide 2% and is moved away from the jaw 29!] by downward movement of this slide. Each of the jaw-closing slides 296 is provided with a. pin 334, and these two pins are engaged respectively by the opposite forked ends of a crossbar 3% pivotally mounted midway between its opposite ends on a pin 388 carried by the yokeshaped lower end of a bar 3!!! (Fig. 14) movably mounted on portions of the two jaw-carrying slides 268 and 210. The bar 3H! is controlled by a rod 352 which is slidingly mounted in a bearing in the upper portion of the casing 256 and extends upwardly into the tubular member 2%!) fast on the casing. Located in this tubular member between a shoulder on the casing 256 and a plunger 3M fast on the upper end of the rod M2 is a spring 3E6 which tends to move the rod in an upward direction. When the rod is thus moved upwardly flanges 318 at the lower end thereof serve by engagement with lugs 320 on opposite sides of the bar 3; to move the bar also in an upward direction and thus to cause the crossbar 3% to operate the jaw-closing slides 2% to close the two pairs of jaws on the upper. As in the machine shown in Letters Patent No. 2,160,846, such upward movement of the rod M2 is permitted by upward movement of a control member 322 which by engagement with the plunger 3 initially holds the rod depressed to maintain the jaws in open relation. In the construction herein shown insurance is afforded that the jaws will thus be held open by mounting in the rod 3E2 a pin 324 and a spring 326 which tends to force the pin downwardly, the lower end of the pin engaging the yoke-shaped portion of the bar 350 to insure that the bar will be held initially as far downward as permitted by the tails 352 or the jaws 292.

It will be understood that the closing of the two pairs of gripper jaws on the upper by the spring-operated rod 35 2 in the manner above described does not affect the relation of the two pairs of jaws to each other. The crossbar 3% through which the two jaw-closing slides 296 are operated is still inclined substantially as illustrated in Fig. 12 after the closing of the jaws, although occupying at that time a higher position relatively to the casing 255 and the jaw holders 2% and 278 than illustrated in that figure. When the casing 256 is thereafter lifted to cause the gripper to pull the upper, the spring 282 yields by reason of the fact that the portion of the upper gripped by the pair of jaws 252 opposes greater resistance to the upper-pulling movement of the jaws than the portion gripped by the pair of jaws 254. That is, the casing 256 and the pair of jaws 25d move upward as a unit relatively to the pair of jaws 252 until the resistance of the portion of the upper pulled by the jaws 25G approximates that of the portion pulled by the jaws 252. In this operation the crossbar 3% assumes a substantially horizontal position, as illustrated in Fig. 13, with the end thereof which is associated with the closing slide for the pair of jaws 252 at substantially the same distance from the upper end of the casing 256 as the other end of the crossbar. It will be evident that this is necessarily accompanied by a lowering of the bar tit? and of the closing rod 352 relatively to the casing 25 against the resistance of the spring 355, so that the force of this spring is added to that of the spring 282 in controlling the pair of jaws 252. In order that both portions of the upper will eventually be pulled with adequate force, mechanism is provided for thereafter rendering the casing 256 positive in its action on the pair of jaws 252 as well as on the pair of jaws 25d. For this purpose there is slidingly mounted on the lower yoke-shaped portion of the bar 3H) a slide 328' provided at its right-hand side, as the parts are viewed in Figs. 12 and 13, with two lugs 33% between which the pin 394 on the closing slide for the pair of jaws 255 extends. On its left-hand side the slide 328 is provided with a single lug 332 for a purpose hereinafter described. It will be evident that the position of the slide 328 relatively to the casing 253 depends on the position of the right-hand pin 3G4 and that when the closing slides 2% are moved upwardly by the rod 3E2 to close the two pairs of jaws on the upper the slide 328 also is moved upwardly as determined by the right hand closing slide 295. The slide 323 has thereon a series of ratchet teeth 3% arranged to be engaged by a tooth 335 (Fig. 14) formed on a pawl 338 which is pivotally mounted on a pin 3% on the cover plate 282. A spring 3 52 seated in a recess in the cover plate and surrounding a. pin 3% on the pawl tends to swing the pawl in the direction to engage its tooth 336 with the teeth 33:3. When the slide 323 is moved upward as above described in the closing of the gripper jaws on the upper the teeth 334 thereon are carried to positions opposite the tooth 336. Accordingly, the casing 255 in its upward movement to pull the upper acts positively through the pawl 338, the slide 328 and the right-hand closing slide 296 on the pair of jaws 254, the spring 214 which controls the jaw holder 21d yielding only enough to permit the tooth 336 effectively to engage one of the teeth 3%. The lug 332 on the left-hand side of the slide 328 serves by engagement with the pin 394 of the left-hand closing slide 2% to limit the relative movement of the casing 258 and the pair of jaws 252 resulting from the resistance of the upper to the force of the pull applied thereto by these jaws. That is, after this pin has engaged the lug 332 force is transmitted positively from the casing 256 through the slide 328 to the pair of jaws 252 as well as to the pair of jaws 254. In the return of the parts to starting positions an inclined face 3% on the upper end of the pawl 338 is engaged by a lug 348 formed on the lower end of the rod 352 to disconnect the pawl from the slide 323, this lug extending outwardly through a slot 353 in the slide 328. It will be understood that as the jaws are closed on the upper this lug movesupward far enough to release the pawl,

The operations of the machine are preferably timed as indicated generally by the cam chart (Fig. 16), the cycle or" operations being in most respects similar to that disclosed in Letters Patent No. 2,160,846. The construction is, however, such that the pulling of the upper heightwise of the last and the wiping of it in the same direction are ehected respectively by difierent cams, identified on the cam chart as updraw and upwipe cams, and the updraw cam completes its operation before the upwipe cam. The upwipe cam also is so formed that after the completion of the first advancing and closing movements of the wipers to wipe the upper over the feather of the insole the wipers are lowered slightly to increase their pressure on the upper before the pressure is relieved to permit the binder wire to be drawn inwardly under them. Other changes as com ared with the earlier disclosure relate mainly to the timing of the spreading movements of the grippers and the time of their release of the upper. The gripper-spreading cam operates mainly after the completion of the updraw, in the course of the upwipe, and the grippers are opened by the gripper-closing" cam just before the wipers wipe the upper inwardly over the insole, objects being to avoid any danger of overstraining light-weight uppers and otherwise to improve the results obtained in the operation of the machine.
