17 Claims.

This invention relates to machines for use in the manufacture of shoes for shaping uppers over lasts or other forms. An object of the invention is to provide a machine for shaping the heel ends of uppers in such manner that preformed heels later applied in contact with the uppers on the heel seats will fit the uppers in accordance with the requirements of the best shoemaking. With this and other objects in view, the invention is herein illustrated asembodied in a novel heel-end lasting machine in the use of which the lasting operation is performed by the operator; but it will be understood that novel features of the invention are likewise applicable to power-operated machines and that in other respects also the invention is susceptible of various embodiments.

A preformed heel, such as a wood heel, applied in contact with an upper on the heel seat of a shoe should, for the best results, t the upper in such manner that the contour of the heel is practically a, continuation of the contour of the .upper heightwise of the shoe without any substantial break at the junction of the heel and the upper. To this end, it is desirable that the upper shall be so formed as to present a definite edge line about the heel seat, and that the con-` tour of the edge line of the heel seat shall correspond substantially to the edge contour `of that portion of the heel which engages the upper at the heel seat. For the accomplishment of these results the present invention, in one aspect, provides a exibly adjustable mold arrangedvto extend about the heel end of an upper on a form and by contact with the upper adjacent to the edge of the heelseat to establish a definite edge line on the upper about the heel seat upon the application of compacting pressure heightwise of the form to an inturned marginal p ortion of the upper, and a templet for determining independently of the form the contour lengthwise of the edge of the heel seat of that portion of the mold which engages the upper adjacent to the edge of the heel seat. The templet has a, contour geometrically similar to the desired contour of the edge line of the heel seat and engages a portion of the mold to adjust the mold as the latter'l is applied about the heel end of the upper. In the construction herein shown the templet conveniently serves also as a member for applying pressure to the inturned margin of the upper as above described, but it will be understood that both functions need not be performed by the samel invention, are wipers which are operated to wipe the margin of the heel end of the upper inwardly over an insole and which are retracted from over the heel seat before the mold is applied about the heel end of the upper, cement being preferably used to retain the margin of the upper in overwiped position. In the construction shown the Wipers comprise afplurality of members which are moved inward rectilinearly in converging paths and serve to localize betweenv them any pleats that develop in the margin of the upper, and they are so formed as to trimv olf the tops of these pleats'and thus to provide a better surface to receive the heel. It should'be understood that in theprovision of such wiping and trimming means the invention is not necessarily limited to mechanism which operates on thevheel ends of uppers.

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying'drawings and thereafter pointed out in the claims.

The machine in which the invention is herein illustrated as embodied is provided with a lower frame 2 having fast thereon an intermediate casting 4 to which is secured a head casting 6. Secured to the head casting by screws 8 is a holddown l the lower end of'which is arranged to engage the heel end of the insole of a shoe on a last to determine the height at which the shoe is positioned for the operation of the 'machine thereon. Slots l2 in the holddown, through which the screws extend, permit it to be adjusted vertically. Mounted for vertical movement beneath the holddown in the casting 4 is a shoesupporting rod I4 on the upper end of which is detachably mounted a block 'It .having a pin 1.8 arranged to extend into the spindle hole in the heel end of the last. A flange 20 on-the rod I4 engages the casting 4 to limit downward .movement of the rod. The rod I4 is moved upwardly to clamp the shoe against the holddown 4l0 by means of a treadle 22 pivoted at 24 on the frame 2 and provided with a roll 2El arranged to engage .the lower end of a Vrod 28 movable in a bearing 30 on the frame. The rod 28 engages and lifts the rod I4 in response to depression of the treadle. To .hold the shoe in clamped position when the treadle is released, there is provided a locking member 32 fast on a shaft 34 rotatable in bearings in the front of the casting 4, the shaft having also fast thereon a hand lever 36. An eccentric face 38 on the member 32 is `arranged to engage an inclined front face 40 on the rod -I4 to lock` the rodfrictionally against downward movement in response to upward movement of the hand lever 36.

,After the shoe has been clamped and secured against the holddown l0 its heel end is lasted by means which will now be described. Before the shoe comes to the `machine it will already have been -lasted at the shank portion, at least in the vicinity of the heel breast line; and preferably, although not necessarily, theheel end of the upper materials will include a counter previously molded to provide an inturned heel-seat ange. Preferably also cement applied to the different layers of the heel-end vportion of the upper materials will be used to secure the .heel endof the upper in lasted position. For wiping the .margin ofat least `the outer layer of the upper inwardly over the insole the ymachine .is provided with a plurality of wipers comprising a pair of side wipers 42, a pair of vcorner wipers v44 and an Vend wiper 46. The two side wipers 42 are secured to the lower faces of wiper carriers 48 which are slidingly movable rectilinearly in guideways formed in a plate 50 supported partly by shelves 52 on the head casting 6 and partly by vertical rods 54 secured to vthe casting 4. Similarly, the corner wipers ,44 are ,secured to wiper carriers 456 and the end wiper 46 to a wiper carrier 58, these wiper carriers likewise being rectilinearly movable in guideways inthe plate 50. The inner end `portions of the wiper carriers have inclined upper faces, as shown in Fig. 3 with reference to the carriers 48, and accordingly in Figs.

-6 and 7 the carriers there shown .appear partly in section and partly in elevation. 'The several guideways for the wipervcarriers are so arranged that in operating on the upper the wipers move inwardly in converging paths until they Ameet over the margin of the upper on the heel seat.

levers B0 are connected to the Wiper carriers 48 by links 63 and pins (i4,y the pins extending through slots in the plate 50, and they are similarly connected to the wiper carriers 56 by links For operating the side'wi'pers 42 and the corner 66 and pins 68. The end wiper 46 is operated by a third lever T0 one arm of which is connected to the end wiper carrier 58 by a link 12 and a pin 74, this lever being pivotally mounted on 'a vertical stud 16 extending upwardly Vfrom the plate 50. The other arm of 'the lever 'ID is connected by a link 18 to the rear end of the left-hand lever 60. The rear arms of the two levers 60 are bilf-urcated and carry rolls 88 engaged by a cam 82 which is mounted to turn on a stud 84 on the plate 50. A spring 486 connectedto the rear arms -of 'the levers tendsto swing these arms toward Aeach other andthereby holds the rolls 8U at all times against the cam 82. This cam is so formed that when it is turned in a clockwise direction (Fig. 4) it operates the levers 6D to impart inward wiping movements to the several wipers, the end wiper 46 being operated from the lefthand lever 6B through the link I8 and the lever 18. The cam is turned by a hand lever 88 mounted on the stud 84 and connected to the cam by a pin 90. A

By reference to Figs. 4 and 8 it will be observed that -the opposite side edges of each of the two corner wipers 44 and of the end wiper v46 extend inwardly in such convergent relation that the edges of the' wipers 44 and 46 which meet over the heel seat, and also the meeting edges of the wipers 44 and 42, are parallel to each other. It will be evident that as the several wipers are moved inwardly in converging paths, any ypleats that are formed yin the margin of the upper, especially in the outer layer of the upper materials if the counter has a molded inturned flange, will be localized between the wipers 42 and 44 and between the wipers 44 and 46. In order to provide a better surface to receive the heel, the wipers are so formed as to trim oi the tops of these pleats by a shearing action thereon substantially at the end of the wiping operation. For this purpose the opposite 'side edges of each of the wipers 44 are formed as cutting edges 92 (Fig. 7) which co-operate with shearing edges 94 and 9B on the side wipers 42 and the end wiper 46 respectively (see Eig. 12).

After the wipers have been` operated as above described, they are retracted from over the shoe by the spring 86 in response to reverse movement of the hand lever 88, and a mold 98 is applied about ythe heel end of the vupper in a relation -to Y the shoe .determined by a templet IBB which serves also as a pressing member 'for pressing the overwiped margin of the upper down on the insole. The mold S8 comprises a substantially U-shaped metal band |02 which is flexible and resilient, a p'ad H14 of comparatively soft rubber secured -to vthe band, and .a mold member |06 also secured to the band and'made of hard rubber or `other suitable material suciently flexible to permit it to assume vdifferent contours lengthwise of the edge of the heel seat, yet :hard enough definitely to shape or mold the upper by pressure againstit. The mold member 108 whenapplied t0 the shoe is arranged tol engage the upper opposite the edge face of the insole and adjacent to the edge `of the heel seat, and the pad |04 is arranged vto extend farther heightwise of the shoe in clamping `engagementwith the upper. Both the position .of the mold lengthwise of the shoe and thecontour'of the mold'member lB lengthwise Aof theedge .of :the 'heel seat are determined by the templet which has a peripheral face |08 (Fig. 9) arranged to be engaged by a. marginal portion of the band |02 extending upwardly beyond the member |03, the face 4|03 having a contour geometrically similar to the desired contour of the edge line of the heel seat. It will be understood'that the pad |04 is suiciently yieldable not to prevent the mold from being positioned and adjusted as determined by the templet.

For supporting the mold 00 and for moving it toward and from the shoe there is provided a slide IIB guided, as hereinafter described, for movements in directions lengthwise of the shoe. Supported by ears AI |2 (Fig. 5) on the fro-nt end of the slide |I0 is a horizontal rod ||4 on the opposite ends of which are mounted forwardly extending arms I6 secured together by atop plate I I8 for swinging movements as a unit about the rod H4 for a purpose hereinafter explained. At their front ends the .arms 6 carry upwardly extending studs to which the plate |8 is also secured, these studs serving as pivotal supports for other forwardly extending arms |22 to which outwardly and rearwardly curved end portions of the band |02 are secured. Screws |24 threaded in rearwardly extending tail portions |26 of the arms |22 are arranged to engage webs |28 on the arms IIB to limit outward swinging movements of the arms |22. The band |32 is of such normal shape that the shoe-receiving opening at thefront end portion of the mold is wider than the heel end of a shoe, and when the mold is applied to the shoe by a forward movement of the slide ||0 the pressure of the heel-end face of theshoe against the pad |04 causes the arms |22 to swing inwardly toward each other to bring the portions of the mold at the sides of the heel end of the shoe to the positions determined by engagement of the templet Iil with the upper marginal por-l tion of the band |02. f

The mold-supporting slide H0 is moved horizontally by means hereinafter described along guideways on a supporting .block |30. To position the mold clear of the wipers when they are operated, it is initially inclined in a downward and forward direction, as illustrated in Figs. 1 and 9, and as it is moved forwardly toward the shoe by the slide |||l after the wipers have been retracted it is swung upwardly to a horizontal position. For this purpose the left-hand moldsupporting arm lhas integral therewith a rearwardly extending arm |32 provided with a roll |34 extending inwardly under a projection |30 on the blo-ck and arranged to be engaged byy a cam face |38 on this projection to impart upward swinging movement to the mold about the rod I4 in response to the forward movement of the slide ||0. A horizontal face |40 on the projection |36 serves thereafter by engagement with the roll to determine the proper horizontal position of the mold. To insure proper clearance between the upper edge of the band |02 and the end wiper 46 a.slot 42 is provided in the band.

The lower face of the block |30 is inclined in a downward and rearward direction and the blo-ck is mounted on correspondingly inclined guideways |44 on another block |46 guided for horizontal movements lengthwise of the shoe on the casting 4. A pin |48 fast in the casting 4 extends upwardly through an opening |50 in the block |40 into a hole |52 in the block |30 and accordingly holds the block |30 against movement in directions lengthwiseof the shoe while permitting itA to move upwardly or downwardly. By such up'- ward or downward movement of the block |30,

`head casting 6. member |00 downwardly and upwardly there is which is effected by movement of the block |46 lengthwise of the shoe, the mold 98 is adjusted to position it at the proper height relatively to the shoe. The adjusting movement of the block is effected by a screw |54 which is threaded in the block and turns in a bearing |56 on the casting 4. A flange |58 formed on the screw at one side of this bearing and'a nut 00 threaded thereon at the other side of the bearing prevent any longitudinal movement of the screw. The screw may be turned by means of the flange |58, after which the nut |00 may be tightened to hold the block |46 in adjusted position.

The slide ||0 is moved forwardly to carry the mold. 38 toward the shoe and to apply it to the shoe by means of a manually operated arm |62 fast on a rockshaft |64 mounted in bearings in the casting 4. Another arm |06 fast on this rockshaft is connected by a link |68 to the slide H0. To hold the mold securely in operative position there is provided a p-awl lli) carried by a third arm |72 on the roclrshaft and arranged to engage the teeth of a ratchet member |14 on the casting 4, the pawl beingheld against the teeth Y by a spring |15.

The combined templet and 'upper-pressing member |00 is supported on the lower end of a bar I'iii vertically movable in bearings in the For moving this bar and the provided a pinion |80 in engagement with rack teeth on the bar, the pinion being fast on a shaft |82 'mounted in a bearing in the casting 5. A rod |84 mounted in a head |86 on the shaft serves as a crank for turning the pinion. The member |00 is so mounted as to permit it to turn, 'for a purpose hereinafter described, about a reduced lower end 88 of the bar |18 the axis of which is in line with the axis of the last-pin I8. It is held detachably in position on the bar by a springpressed pin |90 theinner end of which extends into an annular groove |92 in the reduced end of the bar. Dierent members |00 may therefore be readily substituted for shoes of different sizes or styles. l

In the operation of the machine, the operator mounts the shoe and last on the last pin I8 and by depre-ssion of the treadle 22 moves the rod I4 upwardly to clamp the shoe against the holddown l0, after which he raises `the hand lever 36 to lock the rod 4 against downward movement by frictional engagement of the locking member 32 with the rod. By means-of the hand lever 88 he then moves the `several wipers 42, E4 and 4B inwardly in converging paths to wipe the margin of the heel end of the upper over the insole,'as illustrated in Figs. 8 and 9. As the wipers are thus moved inwardly any pleats which are formed in the margin of the upper, especially in the outer layer of the upper materials, are localized between adjacent wipers, and near the end of the wiping operation the tops of such pleats are trimmed olf by the cutting edges 92 and the cooperating shearing edges 94 and 96 of the wipers, as illustrated in Fig. 12. Thereafter the operator swings the hand lever 88 reversely to cause the wipers to be retracted from over the heel seat. the cement previously applied to the upper being depended upon to retain its margin substantially in overwiped position. By means of the cranky |04 he then lowers the combined templet and pressing member |00 to a position almost, if not quite, in contact with the overwiped margin of .the upper, and by swinging movement of the arm |32 applies the mold 98 about the heel end of the shoe, the mold being moved forwardly by the yslide H and swung upwardly by the action of the cam face 38 on the arm |32. As the mold is thus applied to the shoe its position lengthwise of the shoe and the contour lengthwise of the edge of the heel seat of its upper-molding portion |08 which engages the upper adjacent to the edge of the heel seat are determined by engagement of the peripheral face |08 of the templet |00 with the upper marginal portion of the band |02 (Fig. 10), the sort rubber pad |04 of the mold yielding suiiciently to permit this. By reason of the manner in which the mold is supported it has enough freedom for lateral angular movement to permit it to adjust itself upon contact with each shoe in accordance with any such small variations as there may be in the positions of different shoes about the axis of the last pin I8, and the provision for turning movement of the templet |00 about that aXis permits the templet correspondingly to assume the proper relation to each'shoe as it is engaged by the yband |02 of the mold:

After the mold S8 has been applied to the shoe as above described, it is held in operative position by the pawl |10. lNhile it is in that position the operator turns the pinion |80 to force the member |00 farther downwardly and thus to apply heavy pressure to the overwiped margin of the upper. This pressure serves to compact the layers of upper materials over the insole and to provide an even surface to receive the heel. It also tends to squeeze the upper outwardly against the mold member |00, and this member accordingly serves to establish a definite edge line on the upper about the heel seat, the contour of this edge line being determined by the templet member |00 in accordance with theedge contour of the upper-engaging portionof the heel to be thereafter applied to the shoe. Insurance is thus afforded that the heel will fit the shoe in the most satisfactory manner. The upper may be held under pressure a few seconds if desired, after which the operator returns the mold S3 and the member |00 to their initial positions, releases the shoe support |4 and removes the shoe.
