17 Claims. I

This invention relates to lasting"machines;and

is herein shown as applied to amachine organization of the same general character as disclosed in United States Letters Patent No. 1,843,232 granted on February 2 1932', onan application of B. Jorgensen. While it is an object of the invention, in one asp'ect,*to improve an organization of that character, it is to be understood that the invention is notthus limited in its tip-'- plicability.

Machines such as shown in the above-mentioned Letters Patent are frequently used for lasting tennis shoes or the like whichare com monly made on metal lasts and in the lasting of which the uppers are secured to insoles by adhesion. In such a machine the shoe is positioned bottom upward and is operated upon by opposite side-lasting mechanisms which wipe'the upper heightwise of the lastvin response to downward movement of the last, these mechanismsinelud ing flexible straps which engage the upper frictionally. Associated with the flexible straps are lasting fingers which act thereafter through the straps to lay the marginal DQrtion of the upper inwardly over the insole and to press itdown into position to adhere to the insole, As described in the above-mentioned Letters Patent, the side-lasting mechanisms are thus operated first to last the shank portion of the shoe aqjacent to its heel end and thereafter are moved a short distance lengthwise of the shoetoward its toe end and repeat their operations on the shoe.

The present invention, as appliedto anorganization of the character above outlined, provides the oppositie side-lasting mechanisms with novel means arranged to cooperate with the fiexible lasting straps in controlling the upper. The construction shown comprises members arranged to clamp the marginal portion of the upper against some of the straps, together with means by the action of which these members are caused to assume the required clamping positions with out any attention on the operators part; More particularly, in order not to interfere'with' the presentation of the work to the machine, the

clamp members are-held initially by :a' latch in outwardly retracted positions against the lasting straps, and in response to the movement of an arm whereby the operator starts thepower operation of the machine the members are released by the latch. Upon such release they are [moved inwardly and upwardly by springs to positions over the shoe buttom beyond the upstanding ma nal por o h ppe' iand i m diately thereafter a cam with which the machineis provided moves them reversely downward and outward to positions in which they clamp the upper against the straps. It will be understood that the clamp members, in cooperation with the straps, afford better insurance that the upper will be conformed tightly and smoothly to the contour of the means will be laid inwardly over the insole in the proper manner without the presence of any objectionable wrinkles. Prior'to the completion of the laying'of the upper"in- Wardly over the insole 'itsmarginal portion slips out from between the clamp members and the straps, means' beingfpro'vided for moving the clamp members a'shortdistance upwardly to insure their release of the upper; Since the "use of theclamp ,members is not required when the side-lasting mechanisms operate the second time on the shoe, theyjare released by the above-men tionedcam and are again moved inwardly and upwardlyto positions ever the shoe bottom by the springs after the first operations of the mechanisms remaining in such idle positions during the second operations of the mechanisms. Near the end of the cycle a rise on the cam returns the clamp members to their initial positions against the *lasting'straps, after'whiich the latch, released by return movement of the starting arm, retains them in those positions.

The novel features of the invention will' now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In the drawings;

, and

3 tioned Letters Patent, the drawings show only portions of the complete machine and the description will be confined to such parts as it is necessary to refer to for an understanding of the invention. The machine includes a heel-end support 2 (Fig. I) mounted to slide downwardly in guideways in the frame against the resistance of a spring 4 and carrying a last pin 6 herein shown as extending upwardly into a spindle hole formed in the heel end of a metal last of the kind on which it is customary to make tennis shoes and the like. The last with the upper loosely mounted thereon is positioned by the operator on the last pin in presenting it to the machine, and after opposite side-lasting mechanisms, hereinafter described, have been moved inwardly against the upper on the sides of the last the operator places an insole on the bottom of the last- The toe end of the last and shoe thus positioned 15 supported on a toe rest 8 which is movable downwardly against the resistance of a spring ID. The machine includes mechanisms which need not be described for lasting the toe and heel ends of the shoe. Near the beginning of the cycle of operations the shoe is moved downwardly relatively to the side-lasting mechanisms with the heel-end support 2 and the toe rest 8 by a heel presser foot [2 engaging the heel end of the insole and a toe presser foot l4 engaging the toe end of the insole, thus causing the side-lasting mechanisms to wipe the upper heightwise of the last between the heel-end portion and the ball portion of the shoe. These mechanisms are then operated to lay the margin of the upper inwardly over the shank portion of the insole and to press it down into position to adhere to the insole. Thereafter the side-lasting mechanisms are retracted from the shoe, are moved a short distance lengthwise of the shoe toward its toe end and are again operated to complete the lasting of the sides of the shoe between the portion first operated upon thereby and the portion operated upon by the toe-lasting mechanism. The operations thus briefly outlined are more fully described in the above-mentioned Letters Patent.

As further disclosed in said Letters Patent, the toe presser foot I4 is carried by an arm It which the operator swings forwardly about a vertical axis by means of a handle l8 thereon to position the presser foot over the shoe prior to its downward movement, and this swinging movement of the arm serves to start the cycle of operations of the machine. For this purpose a vertical rod or post 20 to which the arm I5 is secured and which is turned by the swinging of the arm imparts similar turning movement to a collar 22 extending around it, this collar corresponding to the collar 400 shown in said Letters Patent. By its turning movement this collar imparts lengthwise rearward movement to a rod 24 (Fig. 2) the rear end of which engages a screw 26 mounted in one arm of a bell-crank lever 28 pivotally mounted on a bracket on the frame. The other arm of the bell-crank lever is connected by a downwardly extending link 30 to an arm 32 by upward swinging movement of which a clutch 34 is tripped to start the cycle of operations. Through the connections described the arm 32 is thus swung upwardly by the forward swinging movement of the arm I6. The clutch 34 is mounted on a cam shaft 36 by the turning of which operative movements are imparted to the various operating mechanisms.

In general accordance also with the disclosure of the above-mentioned Letters Patent, each of the opposite side-lasting mechanisms, identified generally by the reference character 38, includes a casing 40 mounted to swing toward and from the shoe on a rod 42 which is moved lengthwise to carry the mechanism a short distance toward the toe end of the shoe after its first operation on the shank portion of the shoe adjacent to its heel end. Mounted to swing about each rod 42 within the casing 40 is an arm 44 (Fig. 3) arranged to control a plurality of lasting fingers 46 extending generally widthwise of the shoe and preferably four in number. Associated with these fingers are flexible lasting straps 48, prefer-- ably made of leather, through which the fingers act on the upper, the straps extending heightwise of the shoe and outwardly over the fingers. In the construction herein shown there is one strap common to the two fingers which are nearest to the heel end of the shoe and another strap common to the two fingers which are nearest to the forepart of the shoe. Associated with each strap are two side pressers each comprising an arm 50 pivotally mounted on a rod 52 on the casing 40 to swing widthwise of the shoe and having pivotally mounted on a pin 54 on its upper end a block 58 arranged to press the strap against the side of the shoe, the lower end of the strap being secured to the block. One of the two arms 50 associated with each strap is engaged by a pin 58 slidingly mounted in the casing 40 and controlled by a spring 60 which tends to swing the arm inwardly toward the shoe, such swinging movement of the arm being limited by engagement of a lug 62 on the lower end of the arm with a plate 64 on the casing 40. The other of the two arms 50 is similarly controlled by a spring 66 connected to a finger E8 on the lower end of the arm and to a pin on the casing 40, the finger 68 engaging the plate 64 to limit the swinging of the arm by the spring. It will thus be seen that when the side-lasting mechanisms 38 are swung inwardly toward the shoe the blocks 56 adjust themselves to the shoe and press the straps 48 yieldingly against the sides of the shoe under the influence of the

springs

68 and 86.

Each of the four lasting fingers 45 of each side-lasting mechanism has therein a slot 10 (Fig. 3) and through the slots in the several fingers extends a rod 12 which, in the construction herein shown, is carried by a yoke 14 (Fig. 7) secured on the upper end of the arm 4 Slidingly mounted in each finger and engaging the rod 12 is a pin 18 pressed outwardly against the rod by a spring 18. Accordingly, at the appropriate time in the operation of the machine, the rod (2 acts through the pins 16 and the springs 18 to force the fingers 46 yieldingly inward over the bottom of the shoe to lay the margin of the upper over the insole in response to inward swinging movement of the arm 44 while the casing 40 is substantially stationary. The straps 48 are connected at their outer ends to blocks slidingly movable in inward directions in the fingers 45 against the resistance of springs 82. The fingers, therefore, may slide along the straps as they are moved inwardly over the bottom of the shoe. Under each finger is a plunger 84 pressed upwardly by a spring 86 in the yoke 14, the several springs thus tending to swing the fingers upwardly and thereby maintaining the straps in a taut condition.

Connected to the two casings 40 and tending to swing them inwardly toward the shoe is a spring 88 against the resistance of which they are swung to their outermost positions by the gas-eta rm 4 or t is purpose he cons ruc io h r in; shown, e ch a m r i a stud rran ed to en a e the ca no at e. ou er nd of a slot 92 in the casing. For controlling and operating the arms 44' there are provided two toggle links 94 pivotally connected near their outer ends to the arms by means of pins 95 and pivotally mounted at their :inner ends on'a rod 96, the two toggle links being also mounted to slide lengthwise of the rod 86 to permit them to be moved lengthwise of the 'shoewith the side- .l t m an sm Th rod 96 is s pp ted. in the upper end of a'downwardly extendinglink 98 which corresponds to the link 646 shown .in the previously mentioned Letters Patent. As shown in Fig. 8, the link v98 is pivotally con-'- nected at its lower end to a lever I00 pivotally mounted on a rod I02 on the frame, and this lever is connected by a two-part link" I04 to a lever I06 pivotally mounted on a shaft I08. One part III] of the link I04 is connected to the lever I00 and is hollow to provide a housing for a plunger '2 on the upper end of a rod II4 which serves as the other part of the link and which is connected to the lever I06. A spring 'I I6 engaged by the plunger H2 is arranged to be compressed by downward movement of the rod I I4 relatively to the part IIO of the link to provide a yielding operating connection between the lever I06 and the lever I00. The lever I08 carries a roll H8 arranged to be engaged by a path cam I28 formed in one side of a cam wheel I22 on the cam shaft 36. Initially the arms 44 and; the casings 40 of the side-lasting mechanisms are held in their outermost positions, in which they are shown in Fig. 3, by a pivotally mounted latch lever I24 which holds the lever I00 upraised. Prior to the starting of the machine this latch lever is operated to release the lever I00 by movement of a plunger I26 which the operator pushes rearwardly with his knee, the means for operating the latch lever by the movement of the plunger being more fully described in the previously mentioned Letters Patent. The release of the lever I00 renders the spring 88 effective to swing the side-lasting mechanisms inwardly toward the shoe and thus to cause the straps 48 to be pressed yieldingly against the upper by the arms 50 and the blocks 56; as hereinbefore described and as shown in Fig. 4, ready to wipe thesupper heightwise of the last in response to downward movement of the shoe after the starting of the machine. Such inward movements of the side-last ing mechanisms are permitted by the fact that initially the roll II8 lies in a widenediportion I28 of the path cam I20. This cam is so formed that after the downward movement of the shoe the arms 44 are swung farther inwardly to cause the fingers 46, acting through the straps 48, to lay the marginal portion of the upper over the insole in the manner hereinbefore described As the fingers are thus moved inwardly their inner ends are forced downwardly toward the bottom of the shoe against, the resistance of the springcontrolled plungers 84 by the pull of the straps thereon. Further to'increase the downward pressure on the upper over the insole, an extension I30 of each of the toggle links 04 is arranged to act througha sleeve I32 and a spring I34'to move a device I35 upwardly into position to swing the fingers 46 about the rod 12in the direction to depress their inner ends. The cam I20 is further so formed as to withdraw the sideelasting m c s r m h oe pr para o to the movement thereof toward the toe end of the shoe and thereafter to cause them to operate on the shoe the second time, means being provided for preventing them from being caught-and held by the latch lever I24 when they are thus with drawn, as disclosed in detail in the above-mentioned Letters Patent.

For purposes of this; invention the yokes 14, secured as hereinbefore described to the upper ends of the arms 44, are each provided with upwardly extending side portions which are spaced apart and in the upper ends of which is mounted a shaft I38 (Figs. 3 and 7'). Between the upwardly extending side portions of each yoke is a holder I40 which, by means of members I4I thereon, is hung on the shaft; I38 and provides a guideway for a rack'bar I42 extending widthwise of the shoe, the teeth on the rack bar being engaged by a pinion I44 fast on the shaft I38 between the members I. Pivotally mounted on a pin I46 on the inner end of the rack bar I42 lsa downwardly extending finger I48 which serves as a clamp member for clamping the marginal portion of the upper against one of the lasting straps 48 A'spring I50 connected to the finger and to a lug I52 on the rack bar I42 tends to swing the finger, in an outward direction, its swinging movement in this direction, when it is not in engagement with the upper or with the lasting strap, being limited by its engagement with the end of the rack bar. By swinging movements of the holder I 40 about the shaft I38'the finger I48 may be moved upwardly and downwardly, its downward movement being limited by engagement of the head of 'a screw I54 on the rack bar I 42 with one of the lasting straps 48 and its upward movement being limited by engagement of the holder I40 with a crosspiece I56 carried by the'yoke 14. Secured toone side portion of the yoke 14 are plates I58 and I60 which cooperate with that portion of the yoke to provide a guideway for another rack bar I62 extending upwardlyand downwardly, the teeth of this rack bar engaging a pinion I64 fast on the shaft I38. Pivotally connected to the lower end of the rack bar I62 "is a link I66 the lower end of which is pivotally connected to one end of a lever I68 pivotally mounted between its opposite ends on the previouslymentioned stud carried by the arm-44. Connected at one end to a lug I10 on thelin'k I66 and at its other end-to a pin I12 on the casing 40 is a spring I14 which tends to move the rack bar I62 in a downward direction and thereby to move therack bar I42 in an inward direction, such inward movement of the rack bar, I-42'being limited by engagement of a pin I16 on its outer end with the holder I40. It will be evident that after the pin has engaged the holder the spring I14 'fl lther tends to swing the holder about the axis of the shaft I38 in the direction to raise the finger I48; this movement being limited by engagement of th holder with the crosspiece I56; Accordingly, the springs I14 associated with the opposite side-lasting mechanisms, when permitted by means hereinafter described for controlling the levers I68, move the rack bars I42 inwardly and swing them upwardly to carry the fingers I46 from initial positions in which they are shown in Fig. 3,'where they are held by the springs I 50 yieldingly in-engagement with the straps 48, to the positions over the shoe bottom in which they are'shown in-F-ig- 4.

For controlling the levers I68 there is mounted for turning movement in brackets I18- secured on I 8 0 having fast thereon a "pair --of "arms 1 I82-proacumen.

vided with laterally extending lugs I84 arranged to overlie and engage rolls I86 on the levers I68. It will be understood that the lugs I84 extend far enough to insure cooperative relation between them and the rolls I86 notwithstanding such bodily movements as are imparted to the levers I68 by the swinging of the arms 44. Extending from one of the arms I82 is an arm I88 (Figs. 1 and 3) connected by a link I99 to one end of a lever I92 pivotally mounted between its opposite ends on a member I94 fast on the vertically movable heel-end support 2. The other end of the lever I92 is connected by a downwardly extending link I96 to a lever I99 mounted to swing about a shaft 299. Connected to the lever I98 is a spring 292 which tends to swing it upwardly. It will thus be seen that when the lever I98 is swung in a downward direction it swings the lever I92 in a clockwise direction with reference to Fig. 1 and. through the link I99, swings the arms I82 in a downward direction. By the engagement of the lugs I84 of these arms with the rolls I86 on the levers I68 these levers are swung in directions to impart upward movements to the rack bars I62 against the resistance of the springs I14 and thereby to move the rack bars I42 in outward directions. By reason of friction and gravity the first result of such upward movements of the rack bars I62 is to swing the holders I49 and the rack bars I42 in the directions to carry the clamp fingers I48 downwardly, these movements being limited by engagement of the screws I54 with the straps 48. In this manner the clamp fingers I48 are carried downwardly and outwardly into positions to engage the straps 48 or, at the appropriate time, to clamp the marginal portion of the upper against the straps. Initially, as already suggested, the clamp fingers I 48 are held in retracted positions against the straps 49 as shown in Fig. 3, thus providing room for the mounting of the last, with the upper thereon, on the last pin 6 and the placing of the insole on the bottom of the last. For holding the clamp fingers in these positions there is further provided a latch 294 (Figs. 1 and 3) pivotally mounted on a member 266 on the base of the machine and arranged to engage the head of a stud 298 whereby the link I96 is pivotally connected to the lever I98. A spring 2I9 connected to the latch tends to swing it into position thus to hold the fingers I48, in which position it is shown in Fig. 3,

For causing the clamp fingers I49 to be moved by the springs I14 from the positions in which they are shown in Fig. 3 to the positions in which they are shown in Fig. 4, mechanism is provided for swinging the latch 294 to release the lever I99 by the forward swinging movement of the arm I6 whereby, as hereinbefore described, the operator starts the cycle of operations of the machine by tripping the clutch 34. This mechanism includes a bar 2 I2 secured to the link 39 which is moved upwardly by the forward movement of the arm I 6, the bar 2 I2 being connected by a link 2 l4 to a bell-crank lever 2I6 pivotally mounted on a member 2l8 on the base of the machine and this bell-crank lever being connected by a long link 229 to the latch 294. As the parts are shown in Fig. 1, the latch has been swung into position to release the lever I98 by the forward swinging movement of the arm I6.

When the lever I98 is released by the latch 294 as above described, it is swung upwardly by the spring 292 to carry a roll 222 thereon into engage.-

ment with a cam 224 on the cam shaft 36. In

response to this upward movement of the lever I98 the arms I82 are swung upwardly, thus causing the springs I14 to move the clamp fingers I48 to the positions shown in Fig. 4. Immediately after the starting of the cycle of operations a rise 226 on the cam 224 swings the lever I98 downwardly to cause the arms I82 to swing the levers I68 in the directions to move the clamp fingers I48 downwardly and outwardly in the manner hereinbefore described to clamp the marginal portion of the upper against the straps 46 as illustrated in Fig. 5. Substantially at the same time the shoe is moved downward a short distance by the heel-presser-foot I2 and the toe-presser-foot I4 to cause the straps 48 to wipe the upper heightwise of the last, Fig. 5 showing the parts as they appear after such downward movement of the shoe. It will be evident that since the arms I82 and the lever I92 are carried by the downwardly movable heel-end support 2, the tendency of such movement of the support is to cause the arms I82 to swing in upward directions, but this is substantially compensated for by the fact that the arms are carried bodily downward by the support. The rise 226 on the cam holds the lever I98 depressed until the lasting fingers 46 have been moved inwardly to lay the marginal portion of the upper over the insole as illustrated in Fig. 6. Before the fingers 46 have completed their inward movements the margin of the upper slips out from between the clamp fingers I48 and the straps 43. To afford better insurance that regardless of the width of the marginal portion of the upper extending inwardly over the insole it will always be released by the clamp fingers by the time the lasting fingers 46 have completed their inward movements, there is pivotally mounted on a stud 226 (Figs. 4 and '1) on one side of each of the yokes 14 a lever 239 having an inwardly extending arm 232 provided with a pin 234 arranged to underlie the holder I49 in which the rack bar I42 is mounted. Adjustably secured to the casing 49 by two screws 236 (Fig. 7) is a bar 238 in the upper end of which is mounted a pin 249 arranged to engage the upper face of an outwardly extending arm 242 of the lever 239 in response to the inward swinging movement of the arm 44 relatively to the casing 49 and thereby to swing the lever 239 in the direction to raise the clamp finger I49 (see Fig. 6). The screws 236 extend through a slot 244 in the bar 238 to permit such adjustment of the bar as to vary the amount of upward movement thus imparted to the clamp finger.

When the side-lasting mechanisms operate the second time on the shoe as hereinbefore described, after they have been moved a short distance lengthwise of the shoe toward its toe end, conditions are such that the use of the clamp fingers I48 is unnecessary and even undesirable. Prior to the second operations of the mechanisms, therefore, the rise 226 on the cam 224 releases the lever I98, whereupon the springs I14 move the clamp fingers again inwardly and upwardly to idle positions such as illustrated in Fig. 4. Machines such as shown in the previously mentioned Letters Patent are provided with shoe-removing mechanism which is swung downwardly over the shoe into position to grip the shoe and thereafter removes the shoe from the shoe-supporting means. In order to prevent interference between the shoe-removing mechanism and the clamp fingers I48 and their supports, the cam 224 has thereon a second rise 248 which engages the roll 222 and swings the lever I98 downwardly toward the-end of the cycle of diierations. .By this downjverd 'ewiheih; moverh''fit oi the I'vr the chimp 'fing'ei 's 1118' ar 'retiirh'ed to 'iaesit'ions' Th "eheegenient with the resting street 48.
