ANGELO PEER I, OF WATERTOVVN. 'MASSACHUSETTS, ASSIGNOR :TO REECE SHOE MIACHINERY COMPANY, OF BOSTON, MASSACHUSETTS,

MAINE.

To all whom it may concern Be it known that I, ANGELO PERRI, a citizen of the United States, residing at Vatertown, in the county of Middlesex and State of Massachusetts, have invented a new and useful Lasting Machine, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention is a novel shoe lasting machine. By lasting is understood either or both of the following steps, namely, pullingover the soft leather of the shoe upper at the front and sides near the toe, to conform with the last, and wiping or smoothing the margins of the upper about the last at the toe end, and usually at the heel end also. The present machine may be compared with my prior Patent No. 1,260,034, patented March 19, 1918, and isof the same class, embodyingpulling-over mechanism, toe wiping mechanism and heel wiping mechanism, also a shoe holding device or jack shiftable to change the shoe position after the pullingover, so as to co-operate advantageously with the wiping mechanism. Herein I use the word position in the same sense as in the .prior patent, namely, to refer either to the posture of the shoe or its location.

The main object of the present invention is to afford a machine and mechanism for performing the lasting operations upon a shoe in a more efiicient and more convenient manner and. with better results in the produet. Specifically it is an object hereof to improve as a whole the class of machine illustrated in said prior patent. including the shiftable jack and the relation of the same to the pulling-over and wiping mechanisms. A further object is to improve the pulling-over mechanism per se, the same hav ing utility irrespective of thejaclr and wip ing mechanisms. Other and more particular objects and advantages of the present invention will be made clear in the hereinafterfollowing description of an embodiment thereof or will be apparent to those skilled in the art.

To the attainment of the objects mentioned, the present invention consists in the novel machine. mechanisms, combinations, devices and arrangements herein illustrated. described or claimed. For convenience the shoe will be designated in. the drawings by A CORPORATION OF LASTING MACHINE.

The several component mechanisms which together make up the complete machine are shown in a general way in their co-operative relations in Figs. 1. 3. 17 and 18.. The relative arrangements of the several mechanisms will first he described. and subsequently the structure and operation of the respective mechanisms. The machine and its operation are such that the operator may stand in one place in front of the machine throughout the lasting process on each shoe; the shoe'being easily accessible in its pulling and wiping positions. and the various controlling. adjusting and operating levers. wheels and the like being easily reached by hand or foot. The main frame or base 37 of the machine is shown as provided with an upstanding bracket 38. which supports the jack and pulling-over mechanism. similarly. in a general way. to my prior Patent No. 1.260.034. At the left and right ends of the base are extensions 39 and 410.. above which are supported the heel and toe wiping mechanisms respectively. The general location o'f tie shoe holding jack 43 is between the heel and toe wiping heads and 46, beneath and forward of the gripper devices of the pulling-over mechanism 42; its shoe clamping portion swinging from in front of the grippers forwardly and downiwirdly to a position between the wiping mechanisms. as indicated in the figures.

The initial or pulling position of the shoe is as shown in Figs. 1. 3. 4- and 7, with its toe end pointing upwardly and the sole or bottom of the last facing rearwardly from the operator. The initial location of the shoe ishigher than its final or wiping location. so that as permitted by the illustrated jack. the. shifting of the shoe brings it irom the higher to the lower level. thus giving the greatest convenience to the operator in both the pulling and the wiping operations. Figs. 17. 19 and 20 show the intermediate position of the shoe and jack they having swung downwardly and forwardly. The next shift is aswinging to the right of the shoe heel. so that the shoe and clamp take the final or wiping position shown in Fig. 18. The shoe is here inverted. and the for part of the last is substantially horizontal. with the toe end at the left andthe heel end at the right in proper relations to the toe and heel wiping mechanisms 46 and 4-5. l Vhile the shoe rests in the intermediate position of Fig. 17, the operator may if desired perform the socalled side lasting operations, which are usually hand operations readily performed at this stage of the lasting process.

Before describing the full operation and structure ot the different mechanisms. pulling. jack and wiping, I will state the following novel features of inter-relation. In the use of the machine herein illustrated the shoe initially is positioned by the operator with reference to the position of the pulling-- over grippers. As shown in Fig. 3. the shoe is brought up to the toe gripper and set be tween the side grippers. The shoe at this time is held against the shoe rest or abutment. which is between the gripping mechanisms, and it is not yet engaged by the jack clam). as shown in Fig. 3. In the prior patent the shoe was set to a given height with respect to the jack clamp. and the gripping mechanism was bodily adjusted vcrti cally to the shoe. The present machine is an improvement in that the pulling mechanism requires no vertical adjustment for ditferent lengths of shoe, the shoe being set to the mechanism as just described. When the pulling has been completed. the jack, which meanwhile has remained in its lowered or wiping position. is swung up and the toe pad of the jack clamp comes into position at a predetermined height against the top of the shoe toe. The position or height of the toe pad is initially set in accordance with the pulling-over mechanism. "The heel-end oi the shoe is required to be supported, and the jack comprises a heel spindle adapted to shoe.

enter and engage'the last within the shoe. This in the present machine is adjustable longitudinally in the jack, that is, vertically when applying the jack to the pulled-over Then the toe clamp and the heel spindle have been set and the shoe secured, the pullers may release the shoe, and the jack and shoe may be swung down frontward through 90, the toe pointing front as in Fig. 17. Another feature is that the subsequent swinging of the shoe to set it to the wiping mechanisms is a swinging about an. axis substantially at the middle of the toe end of the shoe, as will be clear in Figs. 18 and 22. In other words, the shoe heel and the heel spindle are to be swung around from the rear to the right, so that the shoe shifts from the Fig. 17 to the Fig. 18 position when it is in readiness for the wiping operations.

it the front of the machine are shown three pedals, 18, 49 and 50,, each having a spring normally lifting it. Pedal 48, after the lasting of a shoe is completed, serves towholly release the shoe from the jack and restore the latterrto condition ready to be elevated to receive the next shoe from the pulling-over mechanism. Y

The central pedal 49'isfor applying by foot the pulling force, it simultaneously operating the pulling grippers at the sides and end of the shoe toe. This pedal when depressed is locked in place, and the right pedal 50 serves the purpose of unlocking the main pedal when the pulling is finished.

Before describing the pulling connections from the main pedal thelocking of the latter may be conveniently explained. Fig. 3 shows that the pedal 49 isfulcrumed at the far rear at 51. About one-third of its length from this point extend the connections to the pullers. About one-third of its length from the front is thefollowing looking mechanism. A serrated rod 52 is fat crumed to the pedal and extends upwardly to a point within a barrel 5-3, seen also in Fig. 2. At the top of the rod 52 is a head 54 sliding vertically in the barrel, and between the head and the bottom of the barrel is a compressed spring 55. The barrel is substantially fixed. but a slight swinging permitted to adapt it to. the movements of the pedal. by reason of a fulcrum 56, connecting the top of the barrel to a projection on the base 37 of the machine. Vhen the pedal is depressed, the descending head .54- compresses the spring 55. which tends to react on release of the pedal to-restore it to its raised position. It will be understood that the pedal will be depressedto varyin extents with different shoes, the shoes being pulled over under observation. It is desir able tolock the pedal in its lowermost position, and this is effected through'the teeth arranged along the length of the rod 52. Near the bottom of the barrel 53 is a pawl 57 slid-- ing horizontally in a fixed guide. A centrally pivoted lever 58' is connected to the.

eration is performed by the separate individual levers at the top of the machine. lVhen the pulling-over is completed, and the jack has been engaged with the shoe, it'is necessary to release the pulling mechanism and permit the opening of the grippers thereof. The pedal 50 serves this purpose. hen depressed it acts through pedal rod 60' to swing a bell crank lever 61, shown in Fig. 1, the free extremity of this pressing lef wardly against the upper end of the lever 58] By this the depression of the puller unlocking pedal 50 removes the pawl 57 from the'toothed rod. 52, permitting the spring 55 to assert itself and restorethe main-pedal 49 to its upp r position.

When the pulling pedal 49 is; depressed, this serves to clos and pull rearwardlyall of the pulling grippers, of which three are shown, one at the extreme toe,and one at each of the two sides of the shoe in proximity to the toe; and these willbe termed the toe gripper 64, the left side gripper 65 and the right side gripper 66, respectively. It

will be convenient to describe the construcand. return movements,- before describing the connections from the pedal 49. During the pulling the shoe, or rather the insole beneath the wooden last, bears againsta system of abutments, threebeing shown, these herein associated respectively with the three grippers, namely, the toe abutment 68, the,

left side abutment 69 and the-right side abutment 7O.

The toe gripper 64 consists,. as seen in Fig.4 of a forwardly and rearwardly sliding shank 72. engaged in a rear bearing 73 and a front bearing 74, while a spring 75 between bearing 73 anda collar-on the shank tends to press' forwardly "the gripper. The spring acting to throw the shanlrforwardly shifts forward and opens the gripper. this action being limited by the contact of the'collar with the bearing/74."

The gripper itself is at the forward end of theshank .72, and consists of a front jaw 76,' mounted on theshank, and area'r jaw 77 pivoted to the shank and having its upward extension pivoted to a longitudinal bar 78, which maybe termed the tail of the gripper, it serving whenpulled 'rearwardly to swing the rear jaw, and thereby close the gripper.- The gripper closing tail 78 isv formed with a hook or notch at 79, engaging on a lug or block 80, loosely surrounding the gripper shank 72 and having lateral pins 81 by which the block may be shifted longitudinally of the shank.

It will be obvious that, if theblock 80 is forced rearwardly while engaged by the book 79, this will first effect the closing of the gripper upon the upper of the shoe, and its continued rear motion will, against the resistance of spring 75, retract the entire toe gripper, thus giving the desired pulling action.

It will be convenient at this point to explain the pedal connections for this purpose. Referring to Fig. 4 in connection with Figs. 3 and 9, an upright connecting rod 84 is shown extending from the pedal lever 49 to a bell crank 85, by which the downward pedal pull is converted into a forward motion of three parallel rods 86, each serving as a connection between the bell crank 85 and a lever 87, of which there are three, as seen in Fig. 9. fulcrumed at a higher point 88. A strong but adjustable spring 89 is interposed between each rod 86 and lever 87 in order to limit the total pulling pressure upon the leather. which without a resilient connection might be unduly stretched and injured by the pedal action.

The three levers 87 at their upper ends have three separate upward extensions, 91 in the center. 92 at the left and 93 at the right, respectively, for communicating the pulling force to the three grippers, respectively. Inasmuch as the grippers are shiftable for right and left shoes, or for adjust ment. or both, the lever extensions 91. 92 and 93 are rendered adjustable or adaptable thereto by their being fulcrumed at 94 to the levers 87, respectively. The extension 91 for the central or toe gripper is formed with a yoke 95 surrounding the block 80. before mentioned, and engaging the pins 81 thereof, so that the rearward movement of the lever pulls rearwardly on the bloek to close and pull the gripper, as described. Fig. 9 shows that the extensions 92 and 93 have similar yokes 95. performing analogous functions for the left and right side grippers. The toe gripper lever has an upwardly extending handle 96, by which the gripper can be additionally manipulated after the pedal operation is completed and the pedal locked downward. Similar handles 97 and 98 for the left and right sides grippers are provided. but not directly on the lever extensions 92 and 93, but through hubs 99 extending from th transmitting levers to the handle levers, as shown in Fig. 9.

Each of the three grippers. in addition to the adjustments to the described, is capable of a bodily shifting or swinging motion adapting it alternately to right and left shoes. The nature and extent of the adjustment of each is dissimilar, and they are, therefore, separately mounted and fitted for this purpose. The toe gripper has the greatest amount of shift for reversing the machine, and this motion and the fittings will be described before describing the side grippers and their movements.

The toe gripper is carried bodily on a composite frame, which is mounted to swing about a point approximately at the ball of the shoe. Fig. 7 shows the gripper set for a right shoe, and Fig. 8 shows the same re versed for a left shoe. The reversing motion is about a center or axis determined by the fulcrum rod or axle 101, supported in a stationary head 102. At the front end of the axle are the following. Extending upwardly from it is a rod 104, on which slides a sleeve 105, carrying the toe abutment 68 before mentioned. A spring 106 presses the sleeve and abutment upwardly against a stop or pin 107, mounted at the underside of the forwardly extending part of the beaaring 74 of the toe gripper shank before mentioned. By this arrangement the toe abutment always takes its correct position both vertically and laterally. Extending downwardly from the axle 101 is a bar 103, having at its lower end a switch cam device, whereby the pulling-over mechanism is automatically reversed after operations on each shoe, as later described.

The axle 101 of the toe gripper system extends through the head 102, and at rearward points is provided with the following. An upwardly extending bracket 109 affords a fulcrum 110, about which the entire toe gripper with its . slide bearings 73 and 74 may be tilted or vertically swung. As seen in Fig. 4, the bearings 73 and 74 are rigidly connected, forming a sort of frame, and by lifting the rear end of this frame the toe gripper can be slightly lowered to bring it into correct relations with the side grippers. This initial adjustment may be effected by an adjusting device 111,comprising right and left threaded rods entering a threaded wheel, which can be turned to raise or lower the rear bearing 73, thus swinging the frame and tilting the gripper, as stated. It will be noted that the yoke 95, see Fig. 3, is slotted to permit the pins 81 on the block at the rear end of the gripper shank to be vertically adjusted. The entire described system also may swing to right or left, the actuating lever 91 being fulcrumed, as already explained, to permit its swinging to accommodate this reversing action.

When the described toe gripper system is swung from right to left or vice versa, the extreme positions are determined by stop devices, shown in Fig. 7. On the stationary head 102 is slidingly arranged a left stop 113 and a right stop 114. Engaging in both of these is a right and left screw 115 having at its central )art a ositionin collar 1 C7 116, held against longitudinal play. At its right extremity the threaded rod has A a thumb nut 117, which may be turned to symmetrically separate or draw together the stops 113, 114, so that they maybe set to suit the shoe being lasted.

I prefer that the described mechanism be automatically reversed after the lasting of each shoe. To assist this purpose a device may be employed for automatically restoring the downwardly extending bar 1O3 to a vertical or central position whenever it is free. Such a device is indicated conventionally by the opposite springs 119. A the foot of this bar, as before stated, is a switch cam device taking part in the reversing operation. This is seen in Fig. 7, and in plan view or diagram in Fig. 10. The switch cam is centrally pivoted at the foot of the bar, and has a wedge portion 120 directed rearwardly, and at each side the cam or reversing portions 121, 122.1 This device co-operates with a slidingcam12at, shown also in Fig. l, mounted to slide forwardly and rearwardly within the open portion of the upwardly extending bracket 38 of the machine. The forward end of this cam or wedge is pointed, and is directed toward the pivot of the switch cam 120. The sliding cam has invariably a straight forward and rearward movement, being normally pulled rearwardly by a spring 125. But the switch cam is centrally pivoted and capable of a slight oscillation so that its wedge or point 120 may pass to either one or the other side of the point of the sliding cam. The stop pins indicated in Fig. 10 limit the swing of the; sw tch cam. In this figure the wedge 120 is indicated as slightly to the right, rather'than to the left, of the point of the sliding can The sliding cam is pushe'd forward at each down-swinging movement of the jack. namely, by means of a lug 126, adapted to be struck by the counterweight of the jack as the latter comes up and forward into position. It will-be understood that the counterweight remains in the position indicated in Fig. 4 throughout the pulling-over operation, and only recedes when the jack is swung upwardly to receive the pulled-over shoe. With the parts normally in the position shown in Fig. 10. the machine just havingpulled-over a left shoe, the sliding cam. as it comes forward with the descent of the jack, engages at the left side of the wedge 120. and this bodily thrusts the switch cam and the carrying bar 103 toward the right. This continues now until the parts come to the dotted line position which is shown, and here the pullers stand reversed for the right shoe. It will be noticed thatin going through this action the switch cam itself is reversed. Its wedge 120, as shown in dotted lines, is

cam, and thus throw the bar 103to the left,

thus setting the machine for a left shoe. When the cam 124 recedes the bar 103 m- .mainsjin its extreme position at one side because at thistime the shoe is in pressing contact against the toe abutment 68. v -To allow for adjustments and prevent breakage, the switch cam is rendered able tof'yieldat strongsprings127 at. the foot of tliebar 103 yieldingly holding the switch cam device to its illustrated position, the switch cam the end of its throw by reason, of'apair of being mounted. to slightly swinger rock about a horizontal axis'for this purpose.

Ithas been explainedhow the toe abut ment 68 followsthe toe gripper not only in,

its swinging, but in its up and down adjustment. The side abutments I69 and 70 are hereincorrespondingly shifted, so that'duroperation on any'shoe the ing the wipin and near the periphery of the shoe. Thus,

in the planview Fig- 11, the left'side abuts i cram lever will bear against the left side gripper 65, thus' bringing the abutment to the proper position.

The side grippers are of as seen in Figs. 11,12 and 13, and elsewhere. The front or outer jaw 131 is almost hook shaped. reaching around in front of the rear or inner jaw 132, the nose of which is suffi'ciently rounded to prevent injury to the upper U. The two jaws are mounted. on a carrier 133, the outer jaw pivoted to move relatively from and to the other, and an equalizing provision is made for the carrier, as seen in Fig, 12, this consisting in parallel links 134:, extending. from the upper and lower parts of the carrier to a centrally pivoted lever 135, connected to the rearwardly extending guide shank 136 corresponding to the shank 72 of the toe gripper. Between'the members 135, and 136 are the following.

a special; form,

l'n order tohold the sidegripper approxi 90 abutments willbe spacedat proper distances, i

somewhat in the pulling action, and with perfect equalizing freedom. The members 138 and 139 are both mounted on an enlargement or head 136 at the forward end of the gripper shank 136. In order that the gripper will not accidentally become rocked away from its illustrated normal position, the pivoted lever 135 is provided with an extension 140 bearing forwardly against an adjustable stop 141 and yieldingly pressed thereto by a spring pin 142, the two last mentioned parts being mounted on the head 136. The equalizing or rocking action is always one in which the lower edge of the side gripper retracts further than the upper edge, which latter is at the cap portion of t-he upper and less apt to yield. The device 141, 142, therefore, permitsthe yielding that occurs in practice, while serving to nor mally restore the parts to the position shown in Fig. 12.

The side grippers are not only carried by the shanks 136, which guide them in their retracting and return movement, but they adjustably swing about these as fulcra in reversing the machine for right or left shoes. Thus, as shown in Figs. 7 and 13, the side grippers are placed for a right shoe, and in Fig. 8 for a left shoe. Each of the axles or shanks 136 is mounted in a pair of bear.- ings 143, front and rear, upstanding from a carriage 144, and these two carriages, as seen in Fig. 4, have a dovetailed connection to the rear side of the stationary head 102. This is for the purpose of symmetrical adjustment of the carriages from and toward each other,.which may be effected by a right and left screw 145, engaging in oppositely threaded lugs 146, and having a thumb nut 147 for effecting the adjustment for variations in widths of shoes.

The swinging of the side grippers for right and left shoes maybe effected and controlled as follows. On the reversing axle 101 of the toe gripper is mounted an arm 149, as seen in Fig. 16, and arms 150 on the side gripper axles 136 are shown as connected to each other by right and left threaded rod 154, turned by adjusting nut 155.

Springs 151 connect the arm 150 with the central arm, so that, when the toe gripper is reversed, the spring at'one side will pull and cause both side grippers to shift, forenample, into the position shown in Figs. 7. 13 and 16. Its extent of shifting is limited by the co-acting stops 152 and 1.53, shown in Fig. 13. The side grippers are thus adjusted in conformity to the shoe at the same time that the toe gripper is shifted across from the Fig. 7 to the Fig. 8 position.

The side gripper shanks 136, like that of the toe gripper, are provided with springs 161, pressing forwardly 'on collars so as normally to hold the side grippers forward and open. Also riding loosely at the rear end of each shank is a block 162, having pins 163, engaged by the yokes 95 through which the pulling-over pedal causes the rearward pulling motions. The shank 136 is merely a guide, and the actual pulling is performed by the side gripper tail 164, which, as seen in Figs. 4, 11 and 12, extends forwardly from the block 162 to the gripper. The tail is arranged to first close the gripper as it starts pulling rearwardly. The front or outer gripper jaw 131 normally stands wide open, it being pivoted on the carrier 133. The hub of the jaw is provided with a few teeth, engaging corresponding teeth. in the hub of a lever 165, extending outwardly and directly connected to the gripper tail 164. I I By this arrangement, when the pedal is depressed, the rearward pull on the tail 164 first closes the gripper, as seen in Fig. 11, and the continued movement bodily retracts the gripper, giving the desired pulling action. 7

Assuming now that the main pedal 49 is lifted and thethree grippers are forward and open, the operator places the shoe approximately as shown in Fig. 4, settin the skirts of the upper within the jaws: of the grippers. The width separating the side grippers and the height of the toe gripper will have been previously adjusted to the style and size of shoe, and other initial adjustments made, after which only the following operations need take place. There is no bodily vertical adjustment of the pullingover mechanism, according to the length of the shoe, but, on the contrary, whatever its length, the shoe is set to the grippers. It is placed with the insole bearing against the three abutments, and the upper within the jaws. By now depressing the main pedal, the three pairs of jaws are first closed and then retracted, iving the desired pulling action. The equalization of the side grippers prevents unequal pulling. When the pedal has been sufliciently depressed, the foot may be removed and the pedal holds its position. The operator may then manipulate the three pulling handles 96, 97 and 98 to give exactly the pulling effects desired. The jack to be described will now be swung up to the shoe, the heel spindle lifted more or less to engage the socket in the last, and the shoe firmly clasped and clamped within the jack. A touch on the pedal 50 now releases the main pedal, thus letting all the grippers move forward and open and release the shoe. The jack will then be swung down and the shoe shifted to wiping position, as will be described. The swinging down of the jack brings its counterweight up and forward so as to act on the reversing cam shown in Fig. 10, so that it will automatically throw the three grippers across to their opposite position, making them ready for the other shoe of the pair. After the wiping and before the jack is lifted, the other shoe of the pair is placed in relation to the grippers, and operations repeated.

Coming now to the shoe holding jack, this is shown in its swung-up position in Figs/1 and 3, and in its swung-down or intermediate position in Figs. 17, 19, 20, 22 and 23, and in its final or wiping position in Fig. 18. The jack mechanism is supported at the free end of a swinging arm 170, fulcrumed at 171 on the upright bracket 38 of the machine. Between the two sides of the bracket is located acounterweight 172, of such form and weight as to substantially balance the jack, thus facilitating its manual lifting and dropping- At the free end of the jack arm 170 it is enlarged or formed into a head 173, affording support to practically all of theshoe clamping mechanism of the jack. In order to position the jack in its swung-down position, the bracket 38 of the machine is formed with a forward extension or web 174, supporting an abutment or contacting piece 175, which is engaged by shoulder 176, formed at the left side of the, free end of the jack arm 170. At this point might also be mentioned the hooked member 177, mounted on the jack, adapted to be swung when the shoe is swung, soas to engage in the slot or recess at the upper side of a boss 178, upstanding from the frame of the machine, to position and steady the shoe against longitudinal motion.

Supported in the head 173 of the .jack arm is the rotary support 180, this extending forwardly horizontally when the jack is in up-swung position, and extending downwardly beneath the head 173 when the jack is in wiping position. Therotary support is held in the head by a suitable flange eneath the head 173 when the jack is in wiping position. The rotary support is held in the head by a suitable flange and collar. At its extremity the rotary supportv 180 rigidly carries a laterally extendingarm or frame 181,'which issecured by key 182 to the rotary support 180. The rotary support carries the toe engaging devices or pads, while the swinging frame 181 carries the underreaching claw devices that engage the shoe sole, and also the heel engaging spindle. It will be understood that this whole shoe engaging or clamping system is bodily swingable in the head 173 of the jack arm, the rotary support 180 forming its axis. I prefer that the-shoe clamping system shall be freely swingable in the jack arm head, and, as shown in Fig. 3,- this enables the operator to readily adjust the jack to the shoe which has been pulled over, while, as seen in Figs. 17 and 18, the clamping devices and shoe are enabled readily to be swung to bring the shoe, into correct is swung into wiping position the hook 177 engages inthe fixed grooveof member 17 8, thus anchoring and steadying the j ack and clamp mechanism-against longitudinal displacements during thezwiping operations.

The toe engaging devices are mountedon what may be termed the upper end of the rotary support 180, it being the upper end when the jack isin wiping position- These comprise a toe pad engaged generally at'184, secured upon the head or block 185, the shank 186 of which extends concentrically within the ,recessed interior of the support 180. g The shankand the support are .keyed together by a key 187, so that all 'ofthe shoe engaging parts will swing together as. a single system. An adjusting screw. 188 enables initial adjustment of the relative position of the toe-engaging pad to allow for shoes. of different thicknesses.

The details of the toe engaging :pad 184;

are shown in Fig. 24 in connection with Figs. 19, 20 and 22. -An equalizing or rocking lever 190 is pivoted directly to the block 185, and the extremities of this lever carry a pair of bent levers 191, each of which carries aninner clamp block 192 and. an outer. clamp block 193, so that we have system of. four self-adjusting clamping blocks bearing against the rear face of the leather or other flexible toe clamping pad member 194;. To render the toe clamping device absolutely universal, each of the four blocks 192,192,198, 193, is pivoted to its carrying lever. Thus, the two inner blocks The heel engaging devices are carried by a sliding carriage 200; well shown in Figs. 20, 22 and 23, this having depending side flanges 201 and a dovetail connection 202 with the top side of the swinging frame 181. The heel spindle carriage 200 is formed with a sleeve or barrel. 203 to contain the spindle. It will be understoodthat the carriage is slid along the frameuntil in properposi- .192 have their shanks extending loosely into tion for the spindle to engage the heel end of the last, and when set it maybe locked in place bya device 205.

The heel spindle 207 is slidingly fitted within the sleeve or barrel 203. A flange 208 at the top of the spindle prevents it from dropping out of the sleeve. Thespindle is provided with a head 209 at the lower end, by which it conveniently may be thrust into shoe engaging position. A spring 210 between the head 209 and the sleeve tends to retract the spindle from the shoe. in order to lock the spindle into engagement with the last, it is formed with teeth or serrations 211, engaged by a pawl 212, the tail 213 of which is formed with an inclined or cam surface to 'co-operate in retracting the pawl, which is spring pressed, toward the teeth of the spindle. For swinging the pawl to unlock the spindle after the completion of shoe, a sliding rod 214 is provided, mounted in the carriage 200, and, as will be later described, this unlocking rod is adapted to be lifted by the depression of the pedal 48 after the wiping of a shoe.

After the toe pad 184 and the heel spindle 207 have been engaged with the shoe, pair of claws or hooks 217 are brought into action against the sole of the shoe to. press the shoe forcibly in position to the toe pad and heel spindle, and thereby rigidly clamp the shoe in the jack. lVhen the jack is swung up to the Fig. 3 position in readiness to engage the shoe after the pullingover, the claws 217 extend substantially as shown in Fig. 3 in readiness to be swung together and pulled forwardly as stated. The fittings and operating devices for the claws will now be described.

Each claw is mounted on a pivoted shank 218, these shanks being pivoted to a sliding sleeve 219, which surrounds the rotary support 180 and gives guidance to the claws in their forward and rearward movement. In Figs. 1.9, 20 and 22, the sleeve and claws are shown in their retracted or forwardly drawn position. Normally they will be in the opposite position. The guide sleeve 219 has lateral ears 220'to which the shanks 218 of the claws are pivoted, and from the pivot the shanks are bent or formed with feet 221, extending toward each other so as to both operatively engage an actuating member 222, which by its relative movements is capable of thrusting the claws apart or together.

The member 222, which is connected to the clawshanks, is provided with a sliding shank 223, having an enlargement 224 at one point, engaging slidingly in a barrel 225, sooured rigidly to the swinging frame 181. Surrounding the shank 223 and confined between the enlargement 22a and the head of the barrel 225 is a spring 226 tending always,

to thrust the member 222 toward the shoe, and thereby separate the claws, a cross spring 227 controlling the claws against excessive swinging apart.

In Fig. 23 in dotted lines is shown the normal position of the claws 217, that is, before they have been applied to clamp the shoe in the jack. It will be obvious that, if the shank 223 be forcibly pulled from the shoe, this will act, first, to throw the claws tow d eachother, the continued movement pulling the claws bodily, as guided by the sleeve 219, until the same are brought into the shoe eng ing position shown in full lines in the figures. Preferably, in order to obviate the claw shanks contacting the sides of the shoe uppers, a pair of adjustable stops 229 are provided on cars 230, extending from the guiding sleeve 219, these stops being so positioned that, as the retractingaction takes place, the feet 221 of the claw shanks engage the stops as the claws reach the desired degree of approach. This'contact is followed by the bodily retraction of the entire claw system.

In order to facilitate the convenient and effective operation of the shoe engaging claws, the following construction may be adopted. The shank 223 of the claw swinging and retracting member 222 is extended through the head of the barrel 225, and at its extremity provided with collars The shank and the collars engage with the U- shaped depending portion 234; of a sliding and rotating sleeve 235, the body of which surrounds the barrel 225. l/Vhen the sleeve 235 is moved toward or from the shoe, this carries with it the shank 223 and the remainder of the claw operating parts. Tn order to effect this operation, the following operating mechanism-may be employed. The barrel 225 is exteriorly threaded, as shown at 238. The external sleeve 235, which slides and rotates outside of the barrel, is provided with an outstanding-lug 239, between which is fulcrumed' a lever 249, extending out-- i. ardly to a point of convenient access, and. formed at its innerextremity as a curved rack or gear 241. The teeth on' the operating lever 240 in the threads surrounding the barrel 225. The gear and screw co-operate in two respects. tirstgin the manner of a rack and gear to give an extend ed movement to the sleeve and connected parts, and thereafter as screw and nut, to give a further and more forcible action. Thus, when it is desired to apply and forcibly clamp the claws against the shoe bottom, the handle 24-0 will be pulled from the shoe. The engagement of the teeth 2&1 with the screw 238 causes the sleeve 235 and connected parts to retract, so that, as before described. the claws 217, which swing together, are drawn forcibly against the shoe. At this stage I prefer to lock the lever 2&0 so as to hold the adjustment. For this purpose, as shown in Figs. 19 and 20, I provide a lock lever 2&3 adjust-ably connected to the operating lever 24:0. The locking lever is fulcrumed on the pivot of lever 240, and its 8X' tremity is slotted to receive a pin 244:, adjustably mounted on the lever 240 by means of a sliding block 245, adjustably shiftable by threaded screw 246. The opposite end 247 of the lever 243 is adapted to engage with the notch or shoulder 248 of a'latch lever 249, mounted on the sleeve 235 and brought into-locking position either by hand pressure. To accomplish this it is only necessary, after the handle 240 has been pulled from the shoe and there locked, to throw pulled leather at those points,

the handle around counterclockwise, thereby rotating the sleeve285 and all the parts carried by it, the teeth 241 during'this action engaging and traveling around the screw threads 225, thus further retracting the entire claw system to any desired extent. During this action it will be understood that the spindle 223 of the claw retracting member 222 is prevented from rotation by the confining of the member 222 between the sleeve 219 and an overlying plate 250.

The tail of the latch lever 249, which in Fig. 19 is shown extendinghorizontally to the left, and which in wiping position will extend horizontally to the rear, is adapted to be contacted and lifted when the pedal 48, previously mentioned, is depressed after the completion of a shoe.

I have herein. provided means for engaging and retaining against the last of the shoe the freshly pulled-over edge portions of the upper. Thus, in Figs. 3, 19, 20 and 22 are shown a pair of opposite retaining members 258. These will be seen in Fig. 3 to be adjacent the side pulling grippers so as to be effective in acting upon the freshly Instead of having the retainers merely press laterally, as indicated in the figures mentioned, they may be somewhat extended and curved around, as in Fig. 25, so as to actually un derreach the shoe sole and more securely re tain the pulled upper in position. There tainer in this case may be applied bGfOla the puller has released the work and traoted, and as soon as the work is released. the retamer 253, not taking the position shown in Fig. 25, may first eifect a smooth-- ing or wiping action of the leather; 'after- I wards holding it in the position shown.-

In either form the retainers 253 are preferably mounted on resilient shanks 254,-

which in turn are mounted onswinging car rier blo cks 255, pivoted'upon'ears 256 on the head 285 of the toe clamping pad. The

- general plan is to swing the carriers 255, and

thereby place the spring shanks under stress, so'that in the modification" shown in Fig, 25,-

the Wiping and retaining action .descrlbed will actually take place'by reason of the pressure and motion of the spring.

' In order to swing the blocks 255, each is provided with a series'of teeth-257 facing each other, and between these runs a dou ble rack 258,the shank 259 of which ex tends axiallythrough the shank 186 ofthc toe clamp pad head, and thence forwardly and axially through the rotary support180, to where at its forward end the shank25t; of-the double rack is provided with a notch or hook by which it may be actuated. Through a' slot 260 formed in the rotary support 180 extends'a finger or elongated tooth 261, adapted to engage in the notch in the sliding shank259, as best shown in Figs. 19 and 20." The finger is normally in its inward position, but maybe moved out wardly by an unlocking lever262, pivoteci exteriorly to the sleeve 219, and act-ed upon by a spring 263, which tends to thrust the finger inwardly. i

The action of the described retainer mech anism is as follows. When the lever or han dle 240 is pulled: forwardly to apply the claws 217 to the shoe sole this, as, previ ously explained, causesthe sleeve 219to slide forwardly. Through the engagement of the finger 261 with the sliding shank 259, the latter "and the rack 258 are drawn forwardly,

and the retainers 253 are thrust toward each other and against the upper of the shoe, as already stated. The connections from the unlocking pedal 48 may now. be described. Extending upwardly from the pedal 48 is a rod 267, which, as will be-clearfrom- Figs. 1 and 3,

is pulled down by' the depression of :the

ing a horizontal arm 270 atits top. This unlocking arm. 270 extends directly beneath the members-which effect the unlocking of .the lever 240 by which the shoe engaging claws are applied, and thepawl 212 by which the heel spindleis unlocked. The relation of theparts is shown'in-Fig. 19, where the unlocking arm 270 is shown to be in position beneath the tail of: the latch lever 249 and the bottom of thepin 214, through which the pawl 212-engages.
