LASTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 365,504, dated June 28, 1887.

Application filed March 18, 1887.

To all whom it may concern.-

Be it known that we, GEORGE W. Corn- LAND, of Malden, J OSEPH E. CRISP, of Somerville, both in the county of Middlesex, and

EDWARD F. GRANDY, of Boston, in the county of Suffolk, all in the State of Massachusetts, all citizens of the United States, have invented a new and useful Improvement in Machines for Lasting Boots and Shoes, .of which the fol- [O lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature. i

The invention is animprovenient upon that I 5 described in Patent No. 359,367, dated October 27, 1885, which describes a machine adapted to last the toe portion of the'uppers of boots and shoes.

It relates especially to the jack or holding 2o device forpresenting a boot or shoe to the toelastiug mechanism; also, to an arm or abutment which is adapted to be moved against the side of the last to hold the same in position during the movement of one section of a toe fitting or clamping strap. or band upon the corner of the toe of the last diagonally oppo- T ings in the bracket a and has a hand-wheel,

site thefefrom.

It also relates to the edge-folding platesaud manner of operating them; also, to the toefitting strap or band and manner of supporting and operating the same; also, to the treadle mechanism for operating various of the parts; also, to treadle-releasing devices and mechanism whereby the parts when released are 3 5 automatically returned to an inoperative position; also, to various details of construction and organization.

In the drawings, Figure 1 is a side elevation of the machine. Fig. 2 is a detail view in perspective of a part of the mechanism for latching and unlatching the treadles, to which reference will hereinafter be made. Fig. 3 is a vertical central section of the machine, showing a last with the upper thereon jacked and presented to the lasting devices. Fig. 4 is a plan view illustrating the arrangement of the various treadles. Fig. 5 is a plan view of the SorialNo.28l,347. (Nomodchl machine, showing, among other things, the position of the side abutment or rest in relation to the toe-lasting devices when in oper- 5o ating position. Fig. 6 is a plan view taken below the upper-folding plates to show the construction and operation of the devices for drawing the band or strap about the toe of the last. Fig. 7 is a view in perspective ofa portion of the device tofurther illustrate por tions of its construction. Fig. 8 is a detail view, hereinafter referred to. Fig. 9 is aplan view of the folding-plates in their closed position.

Thejack Acom prises three principal partsnamely, the heel support or holder a, the toeabutment a, and the downho-ld o The heelholder comprises a block in the shape of a yoke, (see Figs. 5 and 6,) which is fastened upon its side a by the bolt (0 to the swinging arm of. This arm is pivoted at a (see Fig. 1) to a shaft, a, whichhas bearingsin the bracket a and which carries at its end upon the opposite side of the bracket a the segment a". 7:) (See Figs. 1 and 3.) The teeth of this segment are engaged .by the worm (0 upon the worm-shaft a, which is provided with beara, and the rotation of the worm causes the heel-rest to be moved upon an arc of a circle in relation to the downhold a. The yoke a is connected 01'' secured to the arm a to be adjustable thereon to and from its center or shaft a by means of the slot a, formed in the outer end of the arm shown in dotted lines in Fig. 3, and through which the fasteningbolt (0 extends. The yoke (1 also carries the curved or bent spring or flexible metal band B,which is pivoted by its front ends, I) b, to the arms 8 5 of the yoke, so that its rear end may swing or be moved vertically in relation thereto. This metal band or strap preferably is lined upon its inner surface with leather or other suitable material, and is sufficiently thin and pliable 0 to shape itself to some extent to the rear end of the last, which with the upper is encompassed by its inner surface. The band B-also carries a downhold, N, which extends upwardly and inwardly from the upper edge, and is adapted to extend and bear upon the upper surface of the last. (See Figs. 3, 5, and 6.)

In the operation of jacking the shoe the heel end of the last is placed below the dowir hold b and against the inner surface of the band B, and the last is moved forward by the movement of the yoke until the toe end is :0 brought beneath the toe-downhold a, and the end of the tee is forced against the toe-abutment a, (see Fig. 8,) and the last is held clamped in this position by the wormshaft.

A presser, C, to press thelast upward against is the edge-folding plates to smooth or iron out the edge of the upper upon the surface of the insole, is supported at the end of the lever C, which is pivoted at 0, (see Fig. 3,) and which is made vertically movable in relation to the downhold a by the rod 0 and treadle c,

which is adapted to be locked down by mechanism to be hereinafter described, so that the presser is held locked in any positionto which it is moved until released, as hereinafter 2 specified.

The toe band orstrap D is operated or moved by two treadles in successive sections, one of which throws out or moves one section of it from the center of the toe about and upon one 0 corner thereof, and the other of which moves the other section from the said center about and upon the other corner of the toe. The treadles are moved successively. The toe band or strap is fastened to the head (Z at the center of its length, is flexible, and it prefer-' ablycomprises a thin steel spring band lined upon its outer surface with rawhide, leather, or other suitable material. The band is made thin enough to permit or enable it to conform 0 to the curve of the vertical surface of the toe of the last, and each section is held taut while it is being moved against the surface of the last during its entire movement. Thesection of the band which operates upon the corner or section of the last diagonally opposite the abutment or rest E is the one which is first moved. The side abutment, E, is moved into place against the side of the last, as shown in Fig. 5, and automatically locked in that position, before the movement of the toe-fitting strap, and it serves to hold the last against the strain or part of the toe-strap diagonally opposite it, and it is moved against the surface of the last. If the abutment were not used, there would be a tendency on the part of the strap to crowd the last laterally out of a central position. The abutment or rest E has a rounded contacting surface, and is formed upon the end of a lever or arm, 0, which is pivoted at c, and is moved against the side of the last in opposition to the pressure of the spring 0. There is attached to the arm or lever e a pawl, 0 (see Figs. 1 and 7,) which rides upon the ratchet-bar e, the pawl being held in contact therewith by the spring 0". This pawl and ratchet-barserve tolock the a but mentin any position to which it may be moved by hand, and it is automatically released, as hereinafter described.

The strap or band is fastened to the head (I by forming in the head a vertical round hole, (1, and a vertical recess or extension therefrom to the edge of the head of less width than the diameter of the hole, and the band is bent or curved at the center of its length to slip into this recess and hole, and a pin, (1, then inserted into the loop of the band in the hole, so that the band is spread or opened by the pin to fit the bore of the hole, and is thus locked firmly to the plate or head.

d is the section of the band which is first moved or brought into contact with the corner of the last at the toe, and d is the other sec tion of the band. The outer end of the section (1" is secured to an arm, (1, and the outer end of the section (1 to thearm d. These arms d and d are alike in all essential particulars. Each arm has a curved end, (1, over which the band is led to the end-holding clampingbloek (1 passing between the outer section of the holding-plate d and the front or outersurface'of the arm. The clamp d has serrations or teeth which are drawn against the outer surface of the band to clamp it against a serrated surfaee of the arm by means of a screw, d. Each arm is pivoted at d to a slide'bar, which bars are lettered d and d, and it is also connected with the slide-bar by a long coiled spring, d, which is attached at d to the slide bar and at (1' to the outer end of the arm, so that the spring serves to draw the outer end of the arm backward and the inner end of the arm away from the central support of the baud continuously, and each section of the band is always held by or under yielding tension.

The slide-bar d" is operated by the trcadle d and rod (1", the bent lcverd, which is pivoted at d, and the upper end of which is connected by a link, (1 with the end of the slidebar (1. The slide-bar (1 which holds the arm t, is moved by .a treadle, d, which is connected with the slide-bar by a rod, lever, and link similar to those for operating the slide-bar (1.

There are two folding plates employednamely, the folding-plate F and the foldingplate F. (See Fig. 9.) Each plate is moved by a separate lever or handle-thc plate F by the lever or handlef, (see Fig. 5,) which has the cam-pinsff the cam-pin f entering the canr-slotffland is fastened to the inner end of the plate F, and the cam-pinf entering the cam-slotfi, and is also fastened to the plate F. The handlef, for operating the plate F, has the cam-pinsf f the first of which extends through the cam-slotf to the plate, and the second of which extends through the cam-slot f to the plate.

The handlefis adapted to be moved backward with its plate F by means of the spring f, and the handle f and its plate F are moved flz backward autom'aticall y by means of the spring The plates F F have holes or perforationsf, (see Fig. 9,) through which the fastening-tacks are driven, and the plate F has 5 the arm or section f which bears against the edge of the downhold a asthe platerides out, but is shaped upon its front edge, f, so as to wipe or hold the edge of the upper away from the surface of the downhold asit moves. The

to other plate, F, has a corresponding section,

' r 5 outward movementof the other plate, F. These successive movements of the plates bring the recess f in the plate F in position to receive the projeetionf of the platefF.

Thetreadles c d d are adapted to be sue- 2c cessively operated, and to be simultaneously released. This requires that they be automatically locked at the end of their operative movement. The part which'is first moved after the last has been jacked is the side rest 25 or abutment, E, which is moved by hand and automatically locked in -position,as above described. The next part that is moved and locked in place, as a rule, is the ironer G. This is accomplished by the engagement of a latch, g, (see Fig. 3,) on its operatingtreadle c with the teeth 9' of the ratchet-bar g". The ironer moves the upper surface of the last into such relation with the plane of movement of the folding-plates F F that although their movements are in opposition to withdrawingsprings they are held in place by the friction of the upper leather of the shoe against the under surface of the plates untilthe ironer O has been released, when the springs automato ically draw the plates F F back to their original position, or to a position from which they can again be advanced to fold the edge of the upper upon the insole, so that the release of the treadle 0" causes the automatic release of ;5 the ironer C and of the folding-plates F F.

The two sections of thetoe-lasting strap are automatically locked upon the side of the last at the toe by their operating-treadles, the section first operated by the treadle d', and the other section by the treadle d,- and each of these treadles has a springlatch, (see Fig. 4,) which engages the -locking-arms g, and upon the release of the treadles the two sections of the toe strap or band are also returned by their withdrawing springs automatically to their original position. It is very desirable that all these parts should be released simultaneously in order that the upper and last may be quickly removed from the machine,

and this is accomplished by mounting the rackbar and the locking-arms g on the shaft 9 (see Figs. 2 and 4,) and by providing the shaft 9 with a limited extent or degree of rotation, whereby the ratchet-bar g and locking-arms 6 are withdrawn ormoved away from the looks or latches which engage them. This movement .is communicated to the shaft by means of the treadle g, which is fastened to ratchet, which permits the abutment to be drawn back byits withdrawingspring. so that upon the movement of the treadle 9 all the various operative parts are released and permitted to return to their original positions-that is, the ironer C is allowed to release the last. The last dropping permits the folding plates to be moved back by their withdrawing-springs. Each section'of the toe band or strap is drawn backward by its spring, and the abutment E is also drawn back. The shaft 9 is, upon the removal of the foot from the treadle y, returned to a position to bring the lockingbars 9 g into positionto be engaged by the latches g gl upon the treadle by means of springs 9 (See Figs. 4. and 7.)

To permit the ironer G to be moved up and down independently and without releasing the other devices, we employ a supplemental treadle, H, (see Figs. 4 and 8,)the end of which is adapted to engage the rack-bar g of the treadle c" and move it forward or out of engagement with the ratchet-bar 9 while the .treadle C is being moved up and down.

The treadle c is moved downward against the stress of the spring h.

The toe-lasting band may be made of separate links, like a chain, and lined or surfaced withleather, if desired.

The machine is designed to cooperate with the lasting machine described in our application of even date herewith, which is organized to. last the entire upper excepting the toe, and the upper thus lasted is then presented to this toe lasting mechanism, remaining of course upon its last; and in operation the last is placed so that its back end rests against the back strap of the jack, and it is then moved forward by the back strap. until the toe extends under the toe downhold and strikes against the toe-abutment, the back strap being moved by the worm to clamp the last firmly in this position, and'the worm serving also as alock to retain thelast when so clamped. The side abutment is then moved by hand against the side of the last, and, if desired, the toe-ironer moved bya treadle to bring it against the bottom of the last near the toe. The operator then by a treadle draws the section of the toelasting band diagonally opposite from the side abutment, about the toe, from its center around the corner, and clamps the section of the upper with which it is brought in contact firmly against the surface of the last. The

upper edge of this strap should not extend above the upper surface of the insole, and the band when thus strained is automatically locked. The operator then moves by another treadle the other section ofthe toe-lasting strap or band, bringing the portion of the upper about the toe not operated upon by the first section of the strap or band into contact with the toe end of the last and holding it firmly thereto, the edge of the upper which is to be folded over extending upward between the inner surface of the band and outer surface of the last. The right toe-edge'folding plate is then moved into place, folding the portion of the edge of the upper over the first section of the toe-lasting strap or band upon the surface of the insole. Then the other, orleft, plate is moved into position and folds the other section of the toe-edge upon the surface of the insole. The fastenings for securing the edge of the upper to the insole are then driven through the holes in the folding-plates; and if it'is desired to further increase the pressure upon the edge of the upper by the plates, either while they are being closed or afterward, the ironer is forced upward by the treadle to raise the last and level of the insole. Upon the completion of the fastening of thetoe of the upper to the insole the various operating devices referred to-namely, the side abutment, the toeedge-folding plates, the ironer, and both sections of the toe-lasting strap or band-are automatically withdrawn to their original positions, so that the operator is not obliged to move them back or withdraw them, the movement of the releasing-treadle sufficing to release the latches which hold these parts in the position to which they have been moved by the operator, and pcrmitti ng their with drawing devices to return them to their original places; and this leaves for the operator only the turning of the hand-wheel of the worm to move the back strap of the jack sufficiently to unclamp the last.

It will be seen that the last is not jacked in the ordinary waythat is, it is not located upon a pin which enters a pinhole in the heel end of the lastand that the wheel-band as ap plied saves time both in jacking and unjacking the last.
