40 Claims.

1 This invention relates to lasting machines, and is herein shown as embodied in a power-operated toe-lasting machine constructed in many respects as disclosed in United States Letters Patent No. 2,160,846, granted on June 6, 1939 on an application of F. C. Eastmans and A. F. Pyms and in other Letters Patent hereinafter mentioned. It is to be understood, however, that in various novel aspects the invention is not limited to the illustrative embodiment.

An object of the invention, among others, is to provide certain improvements relating more particularly to the lasting of the toes of flatlasted shoes, i. e., shoes in which the marginal portion of each upper lying over the insole extends throughout its width in generally parallel relation to the bottom of the last. Automatic machines for lasting the toes of such shoes with toe-embracing wipers which are shaped to conform substantially to the contour of a shoe around the toe opposite to the edge of the insole require special means for positioning the last and shoe relatively to the wipers. For purposes of this invention the machine herein shown is provided with means for engaging the toe end of the last when the work is presented to the machine to position that end of the last lengthwise and laterally, i. e., with respect to lateral bodily movement, and with additional means for further positioning the toe end of the last angularly, i. e., with respect to lateral swinging movement about an axis at the end of the toe, by control of the heel end of the last. Such additional means, in the construction shown, comprises a substantially V-shaped heel rest which is moved lengthwise of the last into engagement with the upper on the heel end of the last after the work has been presented to the machine. In order that the heel rest will thus properly position lasts of different styles, provision is afforded for determining selectively in accordance with the style of the last the direction of its movement lengthwise of the last and for also efiecting a predetermined bodily adjustment thereof widthwise of the last. As illustrated, the direction of the movement of the heel rest lengthwise of the last is determined by a guide which is adjustable about an axis extending heightwise of the last in accordance with the style of the last and for right and left lasts, the heel rest being adjustable widthwise of the last relatively to the guide. The proper adjustment of the guide for lasts of diiferent styles may be indicated on a chart and will preferably be so calculated that no additional adjustment will be required for different sizes. It is contemplated also that the chart will indicate the corresponding required adjustments of the heel rest widthwise of the last for the different styles.

As common heretofore in toe-lasting machines, the wipers in the machine herein shown wipe the upper around the toe end of the last heightwise of the last, i. e., perform what is known as an upwiping operation, before they wipe the marginal portion of the upper inwardly over the insole. In this operation it is desirable that the wipers apply substantially equal pressures to the upper at the opposite sides of the toe, and for better insurance that they will act in this manner they are so controlled as to permit them to move bodily widthwise of the last in response to pressure of the upper at one side or the other of the toe on the corresponding wiper, the wipers being supported on a wiper carrier which is movable with them widthwise of the last. To insure that in wiping the upper thereafter inwardly over the insole one of the wipers will not move inwardly over the insole substantially farther than the other, the invention further provides means for preventing at that time any bodily movement of the wipers widthwise of the last. For this purpose the construction shown comprises means for centralizing the wiper carrier with respect to lateral movement after the upwiping operation and for locking it against such movement as the wipers wipe the upper inwardly over the insole.

In order to prevent the wipers from acting too severely on the gathers or pleats which develop in the margin of the upper around the end of the toe in the wiping of the upper inwardly over the insole, especially if the bottom of the toe end of the last has a convex curvature, the machine herein shown is further so constructed that after the wipers have started to wipe the upper inwardly they have an appreciable movement progressively heightwise of the last in a direction away from the bottom of the last as they are moved farther inwardly. When the wipers begin their inward movements they are so positioned heightwise of the last as to insure against displacement of the edge of the insole, and as soon as they have wiped the upper inwardly over the extreme edge of the insole they are moved toward the bottom of the last to increase their pressure on the upper before they are m ved progressively in the opposite. directionas a ove described. Substantially at the end of i the inward wipe the wipers are moved toward the bot tom of the last to increase their pressure: on the overwiped margin of the upper. After having thus acted on the upper, in the construction herein shown, the wipers are retracted and are thereafter moved inwardly a second time in wiping engagement with the upper, the second wipe taking place without any progressive movement of the wipers in a direction away from the bottom of the last such as occurs in the course of the first wipe. It is contemplated that cement will be used to secure the upper to the insole, and accordingly the margin of the upper will be held by the cement against any substantial retractive movement between the two wipes.

Under some conditions it may be desirable for the wipers to remain for a few seconds in pressure-applying relation to the margin of the upper after the second inward wipe to allow more time for the cement to set. Provision is, therefore, further aiforded for automatically stopping the machine at that time in the cycle of operations or for optionally eliminating such a stop if desired. In the construction herein shown a cam-operated member arranged to act on a clutch thus to stop the machine prior to the end of the cycle is automaticallydisplaced at the proper time to prevent such stopping of the machine when mechanism controlled by the operator is set to cause such displacement of the member.

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 disclosures in the above-men- I Lil tioned Letters Patent No. 2,160,846 and in others hereinafter mentioned, such parts of the machine a are common to the prior disclosures will be hereinafter described only in so far as is necessary for an understanding of the present invention.

The machine includes a pair of toe-embracing wipers 2 (Fig. 6) for wiping the toe end of the upper heightwise of the last and for thereafter wiping its marginal portion inwardly over an insole on the last. The shoe is presented to the machine by the operator with the bottom of its forepart in engagement with a plate 4 (Figs. 2 andlZ) the lower face of which is curved to con- 1 form approximately to such curvature as the corresponding portion of the bottom of the shoe may have. The plate thus determines the position of the shoe heightwise and with respect to lateral or longitudinal tipping movements. It is detachably secured by means not herein shown on a block 5 which is adjustable about anaxis extending widthwise of the shoe along guideways 7 8 (Fig. 12) formed in an enlarged'lower end portion it of a Vertical rod 12, the block being thus a. adjusted by a screw 14 in the same manner as the block it) shown in Letters Patent No. 2,385,414,

" what is commonly known as a rctarder.

granted on September 25, 1945 on an application of E. A. I-Iolmgrens. The rod i2 is vertically adjustable by a hand wheel l6 (Fig. 1) in the same manner as disclosed in LettersrPatent No. 2,160,846.

When the shoe is presented by the operator as above described the position of the last and shoe lengthwise is determined by engagement of the toe-end face of the last with a device 18 (Figs.

11 and 12) which, as hereinafter'described, clamps the marginal portion of the toe end of the upper out-spread on the wipers 2 to control it in the lasting operation and thus has the function of This device includes a pair of fingers 2i! which are curved to embrace the toe end of the, last and further serve, regardless of the style or size of.

the last, to centralize that end of thelast and shoe laterally, i. e.,'with respect to bodily lateral movement. Substantially at the beginning of a cycle of power'operations of the machine the shoe is clamped against the plate 4 by upward movement ofa'toe rest 22.

granted on December 10, 1940 on an application of F. C. Eastmans. That is, the construction is such that the toerest is forced yieldingly against the shoe first with comparativelylight pressure to control the shoe and is later forced more firmly against the shoe to support it against the downward pressure of the wipers on the margin of the upper. As hereinafter explained, however, the time when it is thus forced more firmly against the shoe is different from the disclosure of said Letters Patent.

Shortly after the beginning of the cycle of operations, when the toe rest 22 is holding the shoe against the plate 4 with comparatively light pressure as above described,a heel rest 24 (Figs. 2 and 4) is moved rearwardlyinto engagement with the heel end of the shoe. This heel rest comprises a V-shaped member 26 towhich is secured a similarly shaped shoe-engaging 'pad 23, and as hereinafter explained it serves not only to assist in supporting the shoe against lengthwisemovement, but also to determine the position of'the heel end of the shoe laterally and The mechanism for operating this toe rest is not herein shown in.

thereby to position its toe end angularly in proper relation to the wipers. The member 26 is provided with a stem 30 (Fig. 2) extending into a bore in a block 32 to permit the heel rest to be adjusted angularly about an axis extending lengthwise of the shoe, and it is held in adjusted position by a setscrew 34 threaded in the block and engaging the stem 38. Mounted in curved recesses in the opposite sides of the block 32 are segmental members 36 (Fig. 3) which are also mounted in curved guideways 38 formed in plates 40 at the opposite sides of the block, these plates being secured to a holder 42 supported on the top of a slide 44.

ed ends extending inwardly into a bore 41 in the block 32, the screws having also unthreaded portions extending outwardly through curved slots 48 in the plates 48 and provided with hand wheels 50 fast thereon for turning them. It will be evident that through the provision of the segmental members 36 and the guideways 38 the block 32 and the heel rest 24 are adjustable upwardly or downwardly about an axis extending widthwise of the shoe to assist in positioning the heel rest in that respect in proper relation to shoes of diiferent styles. After such adjustment the block and the heel rest, are secured in adjusted position by the screws 46, the hubs of the hand wheels 58 cooperating with the screws to clamp the segmental members 36 firmly against the plates 40.

Extending downwardly from the holder 42 into a bore in the slide 44 is a stem 52, so that the holder and the parts supported thereon may be adjusted about an axis extending heightwise of the shoe. The holder is secured in adjusted position by a clamping finger 54 (Fig. 2) which extends into a recess 56 in the holder and engages a horizontal face 58 formed on the holder, the finger being forced down against the face 58 by a screw 60 threaded in a block 62 which is secured to the slide 44. This slide is mounted for rectilinear adjusting movements in directions widthwise of the shoe on a guide 64 which is fast on an underlying plate 66, and it is secured in adjusted position by a thumb screw 68 threaded in the slide and arranged to bear at its inner end against the front edge of the guide 64.

The plate 66 is supported on the top of a block III which is engaged and partially supported underneath by a plate 12 secured to a bracket 14 fast on thefront of the frame of the machine. Rotatably mounted on a stud I6 fast on the plate 66 is a roll I8 which lies in a slot 80 extending widthwise of the shoe in the block 10. Upon movement of this block, therefore, in a rearward direction it acts through the roll I8 to impart rearward movement to the plate 66 and thereby to move the heel rest rearwardly into engagement with the heel end of the shoe. Such movement is imparted to the block by a pair of rods 82 slidingly movable inthe frame of the machine and operated by mechanism not herein shown in detail but which may be assumed to be of the same construction as mechanism shown in the previously mentioned Letters Patent No. 2,160,846 for operating corresponding rods therein shown. The rods 82 in the construction herein shown comprise telescopic parts 84 and 86 (Fig. 2) relatively adjustable to position the heel rest preliminarily for operation on shoes which differ substantially in size, in accordance with the disclosure of Letters Patent No. 2,245,580, granted on June 17, 1941, on an application of F. 0. East- Threaded in the segmental members 36 are screws 46 which have unthreadwill be required for mans. These telescopic parts are shown as dlfferently adjusted in Fig. 4 than in Fig. 2.

It will be evident that the rearward movement imparted as above described to the block 10 by the rods 82 is a rectilinear movement the direction of which is invariable for all shoes. For purposes of the present invention, however, the movement imparted to the heel rest by that movement of the block 76 is a movement the direction of which varies for shoes of different styles and for right and left shoes. For determining the direction of movement of the heel rest there is provided a guide bar 88 which extends through a bore in a block 98 slidingly movable thereon and is secured underneath to a plate 92 supported on the plate 12. A portion of the block extends forwardly and rearwardly through a recess 93 in the block 10, as shown in Fig. 3, and other portions thereof extend upwardly in locations forwardly and rearwardly of the block I8 and are secured by screws 94 to the plate 66 (Fig. 2). It will therefore be understood that the direction of the movement of the heel rest toward the shoe depends upon the direction in which the guide bar 88 extends lengthwise of the shoe. Threaded in this guide bar is a stud 96 (Fig. 2) a cylindrical portion of which extends downwardly through a hole in the plate 12 to provide an axis about which the bar may be adjusted. Extending downwardly from the front end portion of the guide bar through a curved slot 88 in the plate 12 is a bolt I08 on the lower end of which is threaded a hand wheel I02 for securing the guide bar in any position of adjustment about the axis of the stud 96.

In determining how the guide bar 83 should be adjusted it is necessary to consider the fact that the toe-end face of every last is in substantially the same position in the machine and that the longitudinal median line of the bottom of the forepart of each last and shoe should be located in the same relation to the edges of the wipers regardless of the style or size of the shoe. Figure 5 illustrates diagrammatically with reference to three shoe bottom patterns of the same style but of different sizes the positions which the heel ends of the shoes will occupy when their foreparts are in the above-described relation to the wipers. The customary manner of pattern grading is such that what may be termed the middle points a at the heel ends of the patterns all lie on the same straight line b. This line represents the preferred direction of movement of the heel rest 24 as determined by the adjustment of the guide bar 88, so that the guide bar will need to be adjusted only in accordance with style and not for different sizes. It will be understood, of course, that symmetrically opposite adjustments right and left shoes respectively. To indicate the adjusted positions of the guide bar the plate 72 has thereon a scale comprising two series of arbitrarily numbered graduations, one for right shoes and the other for left shoes, arranged to aline with a mark I64 on the front end of the bar. It is contemplated that the operator will have before him a chart indicating by numbers the proper adjustments for shoes of different styles. In addition to the adjustment of the guide bar 88, the swing of the last requires also a bodily adjustment of the heel rest widthwise of the last for difierent styles and for rights and lefts, in order that it will properly position the heel end of each shoe laterally and will thereby determine the proper position of the toe end of the shoe angularly relatively to the slide. id-,the guide fishes,

as estos.-

of the slide for shoes of different styles. For some.

styles-it may be advisable also to adjust the block 42 .and .theheelrest. to some extent about the vertical axis of the stem 52 onthe block.

Asmore fully disclosed inLetters Patent No. 2,1603%, the wipers 2' are, mounted on wiper holderslfltlFig. 6) which are guided for wiper-- closing movements laterally of the shoe in curved paths on a wiper carrier IilB under a cover plate I IQonthe carrier. The wipers are held detachably inplace in slots in the wiper holders by spring pressed pins IE2 (Figs. 6 and 9) which are slidingly mounted in nipples i it fast on the wiper holders and extending through curved slot-s II fi; in the wiper carrier, so thatthe wipers may be readily invertedfor use on right and left shoes and-difierent wipers may be used on shoes of different styles and sizes. The wiper carrier I98 is supportednear advance and retract the wipers lengthwise of the shoeona pairof links I I8 which are spaced apart widthwise ofthe shoe, only one of these links being visible in the drawings. supporting the wiper carrier near its rear end is the upper end of a lever 12% for moving it lengthwise of the shoe, this lever being pivot-ally mounted between its upper and lower ends on a fulcrum rod I22 and being provided at its lower with a roll I2lwhich lies in a path cam Hit on a cam shaft 528. The two links H8 are connected at their lower ends to arms :36 fast on a rockshait I32, and also fast on this rockshaft is an we provided with a roll I36 which lies in a path cam I38 on the cam shaft I23. Through the arm I34, therefore, the wiper carrier is swung upwardly about its connection with the lever I23 to cause thewipers to wipe the upper heightwise of the last and is later swung downwardly and upwardly to increase and to relieve the pressure of the wipers on the marginal portion of the upper over the insole.

In proper time relation to the advancing movements of the wipers lengthwise of the shoe the wipers are closed inward laterally of the shoe, first to engage the upper in the upwiping operation and thereafter to wipe its marginal portion inwardly over the insole, by forward movement of a slide M9 guided on the wiper carrier M38. The mechanism for thus operating the slide MEI need not be herein described in detail, since it is constructed substantially as disclosed in Letters Patent No. 2,160,846. It includes a bell-crank lever M2 pivotally mounted on the wiper carrier I88 and operated by a cam I43 on'the cam shaft I28 to impart forward wiper-closing movement to'the slide Hit selectively through one or the other or both of a pair of springs I4 and I536 arranged to act on theslide through a rod M8. The slide Mu is connected to the wiper holders H35, in the construction herein shown, by yieldable link mechanisms substantially like corresponding mechanisms disclosed in Letters Patent No. 2,354,653, granted on'August l, 1944 on an application of 1 4E, Burbysr Briefly, each of these mechanisms includes a-memberl I50. pivotallycon- This. bodily. adjustment of the. heelirest its front end for movements to A Connected to and xtendsorwardly;at. fr ght; ne es o. fihsv baft 8,3 nected to theslide.

Associated with each i with the members 220. On the front end of the shaft 228 is a hand wheel 232 in position convenient for use by the operator to adjust the wipers as described.

For better insurance that the wipers will apply substantially equal pressures to the upper at the opposite sides of the toe in wiping it heightwise of the last, the construction herein shown is such that the wiper carrier I08 may swing a short distance in a direction widthwise of the shoe in response to pressure of one side or the other of the toe on the corresponding wiper. For this purpose, as shown in Fig. 9a, the connection between the wiper carrier I08 and the lever I20 comprises a rod 234 mounted in the wiper carrier and extending through a bushing 236 in the lever, the rod having midway between its opposite ends a convexly curved portion 238 engaging the bushing and of greater diameter than other portions of the rod within the bushing. To facilitate the swinging of the iper carrier, moreover, the links I I8 are pivotally connected by forwardly and rearwardly extending pins 246 to blocks 242 which are pivotally connected respectively to the wiper carrier and to the arms I30 by pins 244 extending at right angles to the pins 240. While such provision for lateral swinging movement of the wiper carrier is desirable, for the reason above described, in the upwiping operation, it is further desirable, in operating on flat-lasted shoes, to prevent lateral movement of the wiper carrier in response to pressure of the shoe on either of the wipers when the wipers wipe the marginal portion of the upper inwardly over the insole and thus to afford better insurance that one of the wipers will not move inwardly over the shoe bottom substantially farther than the other. The machine herein shown, therefore, is provided with rolls 246 located opposite to the sides of the wiper carrier and arranged to engage cam plates 248 secured on the sides of the carrier. Each roll is mounted on a holder 250 slidingly mounted for movements widthwise of the machine in a member 252 fast on the frame, the holder being controlled by a light spring 254 which tends to move it toward the carrier. Threaded in the member 252 is a screw 256 having on its inner end a stem 258 extending into a slot 260 in the holder 250 to limit the movement imparted to the holder by the spring. Initially the rolls 246 are so positioned that they are substantially in engagement with the cam plates 248 as shown in Fig. 6, but the springs 254 are so light that there is no substantial resistance to such lateral movement as the wiper carrier may receive in the upwiping operation. At the same time when the wipers begin to wipe the upper inwardly over the insole the forward movement of the wiper carrier causes inclined faces 262 on the cam plates 246 to engage the rolls and thus to force them outwardly against the resistance of the springs 254. In this manner flanges 264 on the holders 250 are moved into engagement 252, thus positively insuring that the wiper carrier will occupy a centralized position widthwise of the machine as thewipers are moved inwardly over the bottom of the shoe. Further to insure that the wipers will be moved inwardly substantially equal distances from the edge of the shoe bottom at the sides of the toe, the wiper-closing s1ideI40 is operated through one or the other or both of the springs I44, I46 with such force that the previously mentioned nipples H4 which are mounted on the wiper holders I06 and extend downwardly through the slots H6 in the wiper carrier I08 are moved to positions where they engage the wiper carrier at the forward ends of the slots. Furthermore, the pins I10 carried by the members I50 are moved to the forward ends of the slots I60 in the rods I56.

The cams for advancing and closing the wipers are so formed that after the wipers have wiped the margin of the upper inwardly over the insole they are retracted lengthwise and widlthwise of the shoe substantially from over the shoe bottom and are then operated to repeat their inward wipe over the margin of the upper. In coordination with these inward and outward movements of the wipers they are moved heightwise of the shoe by the cam I38 in such manner that they follow a path indicated by the series of arrows in Figs. 14 and 15. That is, after the upwiping operations they start to move inwardly at such a height as to insure against displacement of the edge of the insole, and just after their wiping edges have passed the extreme edge of the insole (Fig. 13) they are moved downward to increase their pressure on the upper over the insole. From that time until they have substantially completed their inward movements they receive progressively an appreciable upward movement. In,

view of the gathers or pleats which develop in the margin of the upper as it is wiped inwardly, this insures that the wipers will not act too severely on the upper in the first inward wipe, especially if the bottom of the toe end of the last has a pronounced convex curvature. When the wipers have substantially completed the first inward wipe they are forced downwardly to increase their pressure on the upper. Thereafter they are raised and are retracted lengthwise and widthwise of the shoe at such a height as to avoid any outward drag on the overwiped upper, as indicated by the arrows in Fig. '15, the margin of the upper being held by the cement against any substantial retractive movement. They are then lowered and are moved inwardly again, as also indicated in Fig. 15, without any progressive upward movement such as in the course of the first inward wipe and therefore with greater pressure on the margin of the upper, after which they are forced farther downwardly to :apply a final bedding-down pressure to the overwiped margin before they are raised and retracted from the shoe.

Since the wipers 2 as they close present a V-shaped opening between them at the extreme end of the toe, a wiping plate 266 (Figs. 6 and 8) is provided for bridging this opening, so that the upper over the insole will be engaged continuously around the end of the toe. This plate has a slightly convex upper face which is seated in concave recesses in the lower faces of the wipers and it tapers to a thin edge near the wiping edges of the wipers. The plate has integral therewith a downwardly extending arm 268 provided with a pin 210 the opposite ends of which extend into slots 212 formed in flanges 214 which project forwardly from a plate 216 fast on the wiper carrier I08. A spring 218 seated in recesses in the plate 216 and the arm 268 tends to swing the plate 266 in a clockwise direction with reference to Fig. 8 and thus holds it normally in a position determined by engagement of its arm 268 above the pin 210 with the plate 216, the lower face of the plate 266 being in the same plane as the lower faces of the wipers. The slots 212 into which the pin 210 extends are slightly elongated in upward and downward directions and afford leeway for some slight relative movement of the plate 266 and the wiper ascents ll carrier H16 heightwise of the shoe in case of any upward yield of the wipers ,2 in pressing the pper down on the insole.

As hereinbefore explained, the device l8, here- 'in termed a retarder, has a pair of fingers 23 curved to embrace the toe end of the last and arranged to clamp the marginal portion of the toe end of the upper outspread on the wipers to control it during a portion of the lasting operation. Qne of the fingers 20 is so formed as to extend across the end of the toe and slidingly to engage the other finger in a location at one side of the extreme end portion of the toe, as

indicated at 286 in Fig. 11, so that the fingers maybe relatively adjusted widthwise of the shoe without interrupting the continuity of their engagement with the upper all around the toe. The two fingers are supported on a rod 282 which extends through and is secured to the lower end of an upwardly and downwardly extending bar 284 controlled as hereinafter described. Extending upwardly and downwardly at the opposite sides of the lower portion of this bar are two arms 266 also mounted on the rod 232 and connected together at their lower ends by a web 281 in which is a guideway 288 extending widththe rod 'to'vary in that respect their relation to; the wipers. For thus adjusting'the arms 28% i there is threaded in the upper end portion of one 'ofthem a screw 292 which is held against lengthwise movement by an arm 294 fast on the bar 284, this arm having a forked and lying between a' flange 296 formed on the screw and a 'knob 298 on the end of the screw. To secure the arms- 286 in adjusted positions a clamp screw 300' is threaded in the bar 284 and extends through a slot 332 in one of the arms.

"For adjusting the retarderfingers Z3 toward e-rt-from each other there are provided two'latch -members 304 slidingly mounted on a rod 336 which is secured to the bar 284, these latch members extending into grooves formed in portions of the fingers 20 which are above the rod 282. Threaded on the opposite ends of the rod 366 are nuts 308 eachprovided with a flange 3|!) (Fig. which lies in a'groove'formed in the hub of the latch member 3t3 associated therewith. The latch members are normally held connected to the fingers 26 by springs 3l2 which tend to swing them in one direction about the rod 306, but they may be swung against the resistance of the springs by means of arms 3M extending therefrom to release the fingers and thus to permit the latter to be removed from the rod 282 when. it isnecessary to substitute different fingers for shoes'of different sizes.

' The bar 284 which supports the retarder fingers as above described is pivotally supported substantially midway between its upper and lower ends on the forked front end of an arm 3 i 6 (Figs. 1, 10 and 12) which is loosely mounted on a rockshaft 3l8 supported in bearings in a head casting 320 mounted on the. top of the frame of the machine. Integral with the arm 3H5 is another arm 322 which is connected by a spindle 324 to one arm 326 of a three-armed lever 328 fast on the rockshaft 3i8. The spindle 324 is mounted to turn in a-block 330 pivotally'mounted on the arm 322 and is threaded in another block 332 pivotally mounted on the arm 32'6. By'means of a collar 333 and a hand wheel3'36 engaging the block 336 on its opposite sides-the spindle 324is prevented from moving lengthwise relatively to this block, and accordingly turning movement thereof serves to adjust the arm 3R6 and the bar 284 either in a downward =01 an upward direction to vary .the initial position of the retarder l8 heightwise of the shoe.

Faston one end of the rockshaft 318 is an arm 338 which' is connected *by 'a downwardly extending link 340 to one arm 344 of a bellcrank lever 3G6 mounted to turn about a shaft 348. The other arm 3560f this bell-crank lever is provided with .a roll 352 arranged to engage the periphery of a cam 3-54 fast on the cam shaft I28. A spring 356 connected to the bellcrank lever 346 tends to swing the lever in a counterclockwise direction with reference to Fig. l and thus to move the retarder'lB in a downward direction; This action of the spring 356'is supplemented byithe action of another spring 353 which isxconnected atone end to a second arm 330 of the three-armed lever 32.8 and at its other end to a lever 362 which is adjustable to vary the tension of the spring 358 and corresponds to the lever '54 shown in Letters'Patent No. 2,354,663. It will thus be seen that at the proper time in the lasting operation the marginal portion of the upper is clamped on the wipers 2 by the retarder under the combined forces of both springs 356 and 358 and that the clamping pressure may be varied by adjusting the tension of the'spring 358.

In the construction herein shown the cam 354 is so formed and arranged that the retarder I8 is initially inits lowest position; so thatit serves, ashereinbefore described, to position the toe end ofthe shoe lengthwiseand laterally by engagement with the last when the shoe-is presented to the machine; "Theretarder is therefore in position to clamp the upper on the wipers when the wipers have been moved upwardly far enough to cause this action to occur; as illustrated in Fig. 12, after which the wipers may start to lift the retarder. Instead ofrequiring the wipers thereafter to lift the retarder against increasing resistance'of the springs 356 and 358, the cam 354 has on its periphery a gradual rise'c' arranged to act on the roll-352 to lift-the retarder coordinately with the upwiping movement of the wipers, so that afterthe upper has been clamped with the'desired'pressure the pressure thus applied will remain substantially uniform -as the wipers are moved farther upwardly. The time when this rise on the cambecomes effective thus to act on the retarder may be varied by a screw 364 which'is threaded in an arm 366 integral with the arm 338 and is arranged to'engage the head casting 326. That is, by means of this screw the roll 352 may be spaced more or less initially from the periphery of'the cam to vary the time when the rise 0 on the cam begins to. act on the'roll. It will be evident that if the roll is thus spaced initially from the cam and the retarder is initially at the same height the wipers will lift the retarder farther before the cam begins to lift it and accordingly the force with which the upper is ultimately clamped between the retarder and the wipers will be'greater than if the roll is initially in engagement with the cam. Such adjustment of the screw 364 will, of course, vary the position of the retarderheightwise of the a nut 388 13 shoe, but this may be compensated for by turn ing the spindle 324.

As the retarder is thus moved upwardly it is controlled with respect to movement lengthwise of the shoe by a cam plate 368 having therein a slot 318 in which is positioned a roll 312 mounted on the upper end of the bar 284. This cam plate is pivotally mounted on a pin 314 on the head casting 328 and has pivotally connected to its lower end a rod 316 extending rearwardly through an opening in the casting. Threaded on this rod are a collar 318 and a nut 388 arranged to engage the casting respectively on its inner and outer faces for adjusting the cam plate 368 about the pin 314. By adjustment of the cam plate, therefore, the initial position of the retarder with respect to movement in directions lengthwise of the shoe may be varied. To permit a variation in this respect of the initial position of the retarder independently of the cam plate 368 the connection between the bar 284 and the arm 3I6 comprises an eccentric 382 (Figs. and 12) on which the bar is mounted, this eccentric being formed on a stud 384 adjustable in a bearing in the arm 3I6. To hold the eccentric in adjusted position there is mounted in the arm a pin 386 provided in one side with a curved recess (not shown) into which one side of the stud 384 extends, the pin having threaded on its upper end for moving it lengthwise to locl: the stud.

The retarder I 8 is preferably so adjusted about the rod 282 by means of the screw 292 (Fig. 12) that it clamps the upper on the wipers first at the end of the toe, the wipers occupying at this time a position in which they are somewhat inclined lengthwise of the shoe. As the wipers are thereafter swung farther upward they arrive in positions in which the retarder is effective to clamp the upper upon them also along the sides of the toe. It will be evident that by means of the screw 292 the pressures applied by the retarder to the upper at the end and the sides of the toe respectively at the completion of the upwiping operation may be relatively varied as desired.

Associated with the retarder I8 is a holddown 398 for engaging the marginal portion of the toe end of the insole to assist in preventing its displacement as the wipers wipe the upper upwardly and begin to wipe it inwardly over the edge of the insole. This holddown comprises a pair of curved fingers 392 (Fig. 11) pivotally mounted on a stem 384 (Fig. 13) which extends downwardly from a block 396 and held in place bythe head of a screw 398 threaded in the stem. A spring 488 mounted in recesses in the fingers and held in place by pins (not shown) extending within it from the fingers tends to swing the fingers outwardly and thereby holds them against the inner faces of the retarder fingers 28. Accordingly the holddown fingers assume positions determined by the adjustment of the retarder fingers widthwise of theshoe and require no separate adjustment for shoes of different sizes. The block 396 is pivotally mounted on a pin 482 extending widthwise of the shoe in the lower end of an upwardly and downward- 1y extending slide 484 mounted in guideways in the arms. 286. The holddown 398, therefore, may adjust itself to the bottom of the shoe about the pin 482. When thereis no. shoe in the machine it is held in a definite position with respect to movement about the pin by a spring-pressed pin 486 mounted in the slide 404 and having on its lower end a head488 arranged to engage a flat face on the block 396. The slide 484 is under control of a spring 4I8 which tends to move it downwardly, the spring being seated at its upper end against a cap member 4I2 which partially incloses it and which is secured on the upper ends of the arms 286. To hold the lower end portion of the spring in place a pin M4 extends upwardly within it from the slide 484. For determining adjustably the height at which the holddown 398 is initially positioned there is provided a bell-crank lever H5 pivotally mounted on a pin M8 in the block 6 (Fig. 12) with one of its arms 428 in supporting engagement with the lower face of a projection 422 on the lower end of the slide 484. The other arm 424 of the bell-crank lever is forked to straddle a screw 426 which is rotatable in the block 6 and has a hand wheel 428 thereon for turning it. Threaded on the screw is a nut 438 in contact with the arm 424 and prevented from turning by engagement with the block 6. A spring 43I acting on the arm 428 holds the arm 424 at all times against the nut. The slide 484 is preferably so adjusted by the screw 426 that the lower faces of the holddown fingers 382 are slightly lower than the lower face of the shoe-positioning plate 4 when there is no shoe in the machine, so that when the toe rest 22 is moved upwardly the holddown will be lifted slightly against the resistance of the spring 458 by engagement of the shoe therewith, thus insuring that it will be effective to press the marginal portion of the insole down on the last.

For withdrawing the holddown 398 from the shoe to clear the wipers as they wipe the upper inwardly over the insole a third arm 432 of the three-armed lever 328 is arranged to engage a nut 434 held in adjusted position on a rod 438 by a lock nut 438 (Fig. 10), the lower end. of the rod 436 being pivotally connected to an arm 448 projecting from the slide 484. The nut 434 is initially spaced from the arm 432'far enough to permit the upward movement of the retarder I8 with the wipers in the upwiping operation Without disturbing the holddown 398. When the wipers, as they begin to wipe the upper inwardly over the insole, arrive in positions substantially as shown in Fig. 13, an abrupt rise at (Fig.1) on the cam 354 moves the retarder I8 quickly upward away from the Wipers, and at the same time the arm 432 acts on the slide 484 to move the holddown 398 upwardly out of the paths of the wipers.

The means for driving the cam shaft I28 and for starting and stopping the cycle of operations of the machine are, except as hereinafter noted, of the same construction as shown and described in Letters Patent No. 2,160,846. Briefly, there is fast on the cam shaft a gear Wheel 442 (Fig. 1) engaged and driven by a worm 444 which is fast on a shaft 448 at right angles to the cam shaft. Normally rotatable about the shaft 446 is a clutch member 448 driven continuously by an electric motor 458, and connected to this shaft to turn therewith is a cooperating clutch member 452 movable lengthwise of the shaft into or out of frictional engagementwith them ember 448, the member 452 being held in such engagement when the machine is operating by means of a spring 454. To withdraw the member 452 from the memher 448 and thus to stop the operation of the machine there is provided a yoke member 456 mounted for swinging movements and connected to the hub of the member 452. Connected to the since it is held yoke member to swing therewith is an arm 458 (Fig. 16) on which is secured a latch member 468 normally engaged underneath by a shoulder 461 formed on a block 462 to hold the yoke member in such a position that the clutch member 452 is out of engagement with the member 44%. The block 462 is mounted on an arm 484 which is pivotally supported at its upper end on one arm of a bell-crank lever dSB pivotally mounted at 468 on a lug on the frame of the machine. The other arm' of this bell-crank lever carries a roll 41!] engaged by a path cam 112 on the cam shaft !28. A spring M4 connected to the arm 4S4 tends to swing it in a rearward direction to hold the block 462 in operative relation to the latch sec. The lower end of the arm 464 extends through a slot formed in a substantially horizontal forwardly extending bar 416 and below the bar carries a pin 4T8 arranged to engage a shoulder 48!] on the bar. The bar 416 is pivotally connected at its front end to an arm 582 fast on a rockshaft 684, and a spring E86 connected to this arm tends to swing it in a rearward direction and thus to hold the rear end of the bar 416 against a stop 488. The rear end of the bar Q16 is, moreover, supported on the upper end of a screw 49!] and is held down on this screw by a spring 492. Also fast on the roclzshaft A34 is a treadle 495. It will thus be seen that when the treadle is depressed the bar 416 is moved in a forward direction and down by the spring 492 it swings the arm 46% forwardly by engagement of its shoulder 48B with the pin M8 to disconnect the block 462 from the latch ist. This permits the spring 455 to force the clutch member 352 into engagement with the member M8 to start the operation of the machine. For bringing the machine thereafter to a stop, the arm 554 is lowered by the action of the earn 512 on the bell-crank lever 456, thus disengaging the pin H3 from the shoulder 480, if the operator has not released the treadle, and permitting the arm to be swung by the spring 474 to carry the shoulder 66! again under the latch member diiil, after which the arm 464 is lifted to swing the yoke member Q58 in the direction to disconnect the clutch members from each other. In the construction herein shown the cam 412 is so formed as to bring the machine thus to a stop not only at the end of the cycle, but also before the of the cycle when the wipers have completed their second inward wiping movements, to allow more time for the cement to set while the upper is held under pressure by the wipers. The operator thereafter starts the machine again by depression of the treadle to cause it to complete the cycle.

Under some conditions it may not be necessary to bring the'machine to a stop as above described to permlt the wipers to dwell on the margin of the upper. The machine herein shown is therefore provided with means for optionally rendering the cam M2 ineffective to stop the machine before the end of the cycle. For this purpose a bell-crank lever A95 is mounted to swing about the same axis as the yoke member 456 but independently thereof, one arm 498 of this lever carrying a roll 5% engaged by a peripheral cam 582 on the cam Shaft L28. A spring 5% connected to the other arm 5% of this bell-crank lever holds the roll 595 against the cam. The arm 5% is forked to provide a guideway for an upwardly and downwardly movable slide 5138. Threaded in 2; lug M on this slide is the lower end of a rod '5l2, the upper end of which is connected by a link M to one arm of a hand lever 516 pivotally mounted at M3 on theframe of the machine. By the hand lever M6, therefore, the slide 508 may be moved upwardly or downwardly along its guideway in the arm 5% to one or the other of two different positions determined by .asprin gpressed pin 52% on the lever and two holes 522 formed in the frame to receive the pin. As the parts are shown in Fig. 1 the slide 568 is in its lowermost position with its lower end portion directly at the 526 on the arm @5 2. The cam 5&2 is so formed that before the cam M2 becomes effective to stop the machine prior to the end of the cycle it swings the bell-crank lever 496 in a counterclockwise direction with reference to Fig. 16 and thereby causes the lower end of the arm 5% to engage the pin 52 i and swing the arm tilt in a forward direc tion so that when the arm is raised by the cam M2 the shoulder dill will not engagethe latch its and, therefore, will not stop the machine. It will be understood that the cam 5 92 will perunit the bell-crank lever 496 to by the spring are before the end of the cycle,so that it will not interfere with the stopping of the machine at the end of the cycle. If it is desired that the machine shall come to a stop prior to the end of the cycle at the time when the wipers are over the bottom of the shoe, the operator moves the lever 515 to withdraw thelower end of the slide 5% from its position at the rear of the pin 5%. With the slide thus withdrawn, it will not engage the pin when the bell-crank lever 49% is swung as above described by the cam 5M, and accordingly the cam M2 will not be prevented from bringing the machine to a stop prior to the end of the cycle.

The manner of aeration of the machine, in so far as it is of interest with reference to the present invention, will now be briefly summarized. It will be understood that before the shoes come to the machine the toe end p'ortionsof the uppers are trimmed. as customary prior to cement toe lasting, so that for the most part the margin of the outer layer only of the upper materials of each shoe will lie next to the insole and will. be secured thereto by the cement previ viously applied to the shoe. Prior to the use of the machine on shoes of a given style the op erator adjusts the bar 8% which guides the heel rest in its movement toward the shoe by swinging the bar laterally to the position required for shoes of that style, which may be indicated on a chart, making the proper adjustment by reference to the scale on the plate '52. If the shoes immediately to be operated upon are right shoes the adjustment is made by reference to the right-hand portion of the scale andif they are left shoes it is made by reference to the lefthand portion of the scale. The operator also adjusts the slide 46, along the guide it to a position which may likewise be indicated on the chart, bringing one end or the other of the slide into registration with the proper scale mark on the guide. In this manner the heel rest is properly positioned initially widthwise of the shoe relatively to the guide bar 918. If desirable, moreover, the heel rest may be adjusted about the vertical axis of the stem 52 or in an upward or a downward direction along. the curved path determined by the guideways 38 (Fig. 2).

In presenting the shoe to the machine the operator moves it to a position in which the bottom of the fore'part of the insole is in engagement with the plate 4 and the holddown 3% and the toe end face of the last is in engagement with rear of a pin 524 mounted ina lug.

be swungreversely the curved fingers 20 of the retarder I8, these fingers having been preliminarily adjusted in accordance with the width of the shoe and having by their adjusting movements correspondingly adjusted the insole holddown fingers 392. The retarder l8 accordingly determines the position of the shoe lengthwise and the position of its toe end laterally. After thus presenting the shoe the operator starts the machine by depression of the treadle 494 (Fig. 16). Substantially at the beginning of the cycle of operations the toe rest 22 is moved upwardly to clamp the shoe yieldingly against the plate 4 with comparatively light pressure. If the holddown 390 is so adjusted that the insole-engaging faces of its fingers 392 are initially slightly lower than the insole-engaging face of the plate 4, it is raised by the shoe as the shoe is forced against the plate 4 by the toe rest. Shortly after the upward movement of the toe rest the rods 82 are moved rearwardly to carry the heel rest 24 into engagement with the heel end of the shoe. The heel rest is thus moved in the direction determined by the adjustment of the guide bar 88 and upon engagement with the shoe determines the position of the heel end of the shoe laterally. In this manner, as hereinbefore explained, the toe end of the shoe is properly positioned angularly in relation to the Wipers which are to operate thereon. If the heel rest, upon such engagement with the shoe, causes the heel end of the shoe to move a short distance laterally in one direction or the other, such movement of the shoe is facilitated by reason of the fact that the toe rest, as above explained, is at that time holding the shoe with comparatively light pressure.

In proper time relation to the operations above described the wipers 2 are advanced and closed about the toe end of the shoe and are swung upwardly to wipe the upper heightwise of the last. When they arrive in the positions indicated, for example, in Fig. 12 they clamp the upper, which is outspread over their top faces, against the retarder l8 and may then start to lift the retarder against the resistanceof the springs 356 and 358. At a time, however, depending upon the adjustment of the screw 364 (Fig. 1) the rise on the cam 354 becomes effective to lift the retarder coordinately with further upward movement of the wipers while maintaining the clamping pressure on the upper substantially uniform. During the upwiping operation the wiper carrier I68, as hereinbefore explained, may swing slightly in one direction or the other widthwise of the shoe relatively to its operating lever I26 in response to pressure of one side or the other of the toe on the corresponding wiper to assist in equalizing the pressures of the wipers on both sides of the toe.

- After the completion of the upwiping operation the wipers are further advanced and closed to wipe the marginal portion of the upper inwardly over the insole, the retarder at first still maintaining its clamping pressure on the upper. Shortly after the beginning of this inward wipe, when the wipers have arrived substantially in the positions illustrated in Fig. 13, the abrupt rise d on the cam 354 (Fig. 1) moves the retarder upwardly away, from the wipers to release the margin of the upper and moves the holddown 390a1so upwardly awayfrom the insole. At approximately the same time the force applied to the toe rest 22 is increased to supportthe shoe morefirmly against downward pressure of the Wipers. The wipers begin their inward wiping movements at such a height as to insure against displacement of the edge of the insole, and when they arrive substantially in the positions illustrated in Fig. 13 they are moved downwardly to increase their pressure on the upper over the insole. Thereafter, as they are moved farther inwardly, they receive progressively an appreciable upward movement until they have substantially completed their inward Wipe on the upper to prevent them from acting too severely on the gathers or pleats which develop in the margin around the end of the toe. When the wipers have substantially completed their inward movements they are forced more firmly down on the margin of the upper. The manner in which the wipers thus act on the upper-in wiping it inwardly is indicated by the directions of the arrows in Fig. 14. Substantially at the beginning of this operation the wiper carrier I08 is centralized with respect to lateral movement and is locked against such movement by the action of the cam plates 248 on the roll holders 250 (Fig. 6). After the first inward wipe the wipers are raised and retracted and are thereafter moved downwardly and are advanced and closed a second time in wiping engagement with the upper as illustrated by the arrows in Fig. 15, their downward pressure on the upper being again increased at the end of the second inward wipe. The wipers are thus moved inwardly the second time without any progressive upward movement such as they receive in the course of the first inward wipe and therefore with greater pressure on the margin of the upper.

If the hand lever 5l6 is positioned as shown in Fig. 16 the wipers are thereafter lifted and retracted from over the shoe and the parts of the machine are returned to their starting positions, the machine coming to a stop only at the end of the cycle, since the cam 502 by its action on the bell-crank lever 496 prevents the stopping of the machine prior to the end of the cycle, as hereinbefore explained. If, however, the hand lever has been moved to retract the slide 508 from its position at the rear of the pin 524, the machine comes to a stop with the wipers in the positions indicated in Fig. 15 to allow more time for the cement to set while the margin of the upper is held by the wipers. In that case the operator starts the machine again after the desired interval by depression of the treadle 494 to cause it to complete the cycle.
