LASTING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 251,487, dated December 27, 1881.

Application filed August 5, 1881.. (N0 model.)

To all whom it may concern:

Be it known that we, HENRY G. THOMPSON and SAMUEL E. MOWER, of Milford, New Haven county, State of Connecticut, have invented an Improvement in L&Stll]g-1VIElCllll'l8S,Of which the following description, in connection with the accompanying drawings, is a specification.

This invention in lasting-machines is an improvement on the machine represented in United States Patents Nos. 193,446, 208,127,

and 212,824, to which reference may be had, the object of the present invention being to improve the construction of some of the parts and add to the machine novel devices, whereby better results may be obtained and the operation of the parts and their adjustment for work with different-sized lasts be improved.

In our present machine we have slotted the shanks ot' the toe and heel pullers or jaws, and operated them by a pin carried by the tipping plate. YVe have provided the tipping plate with a screw, whereby it may be adjusted horizontally to bring the fulcrum of the said pollers in line with the center of the last. We have placed the shanks of the ball and shank pullers in sleeves, and surrounded them by adjustable spiral springs, and have pivoted the forward parts of the ball-pullers so as to turn toward the toe of the last, when subjected to strain, to take up the slack in the upper at the shank of the shoe. o have made the shank and ball pullers simultaneously adjustable by means of a righ t-and-left-hand screw, and have made the said ball and shank pullers vertically adjustable, and have adapted them to be closed and opened byarack-bar and pinion. The head carrying the working parts is pivoted so as to both tip and rotate. The extent to which the head may tip is controlled by adj listing-screws, and the head has cooperating with it a looking device to hold it in upright or horizontal position.

Figure 1 represents, in side elevation and partial section, the main part of a lasting-inachine containing our improvements; Fig. 2, a partial section thereof on the dotted line 00 m. Fig. 3 is a top view of Fig. 1, Fig. 4, an end view of our improved machine, the base being broken out to show part of the head-locking device, the other portions not therein shown being delineated at the lower part of Fig. 1;

Figs. 5 and 6, details of the toe-rest; Fig. 7, a sectional detail, showing one of the shank-pullers and means for operating the same, one of the levers carrying one of the pair of shankpullers being broken away; Fig. 8, a partial side elevation of one of the shank-pullers detached; Fig.9, a side elevation and a top view, partially in section, of one of the ball-pullers; Fig. 10, a detailshowing the carriage which carries the support for the tipping plate at the heel of the last, screw to adjust it, the slide for the shank-pullers, and the right-and-left-hand screw for moving it and the carriage for the ball-pullers; and Figs. 11 and 12 are details of one of the tipping plates and pullers to operate upon and lay the upper over upon the heel or toe of the last.

The head A,which contains the moving parts of the machine, is supported by a pivot or pin, 2, held by checks 3, rising from a rotating collared sleeve, 4, the shank of which, inserted into the base B and grooved, as at 5, Fig. 1, receives a screw, 6, that permits the sleeve to rotatein and prevents it being lifted from the said base. The checks 3 carry a stop, 8, (shown as-a screw,) and the lower part of the head A has two adjusting-screws, 9 10, the ends of which may be made to strike against the stop 8.

These screws may be adjusted out or in to any desired position, and enable the head A to be tipped more or less from ahorizontal position,

it turning on the pivot 2, to hold the head A in a horizontal position as long as may be desired. Its lower end is provided with an opening to receive the end of a locking device or bolt, 12, extended through a spiral spring, 13, and down into the hollow base B, where it is connected by asuitable link with a foot-treadle, 14, the bolt being withdrawn, when it is desired to tip the head, by depressing the said treadle. The upper part of this head A is grooved, as show u in Figs. 5 and 7, to receivethe dilferent carriages which support the lasting devices.

The toe and heel pullers or closing jaws or slides C C at their forward ends are made as in United States Patent No. 212,824; but their shanks are provided with inclined slots a a, each pair of slots receiving a pin, b or I), fixed on one of the tipping plates, d or d, pivoted at or near their front ends on a horizontallymovable plate-adjusting screw, e or 6, having a milled head by which to turn it. Each of these adjusting-screws is fitted into the screwth'readed upper ends of upright rodsforf, extended down through sleeves g or g, each rod being provided with rack-teeth, as shown in Fig. 1. The screws may be turned to adjust the tipping plate d laterally to the right or left, to keep the center pivot of the pullers 0 always at the proper position with relation to a longitudinal central line drawn through the last from heel to toe. The pivot h of the pullers'G rises from aslidingblock, i, grooved atits sides, (see Fig. 11,) and fitted into a slot at the front end of the tipping plate (I.

The blocks and pullers or jaws thereon are moved backward and forward with relation to the tipping plate 01 by a hand-lever,j, having a link, k,joined by a suitable screw with the said carriage, as in Fig. 12, the pullers O, as

they are moved forward, being gradually closedas their slotted shanks are drawn forward over the stationary pin 1). Slottin g the shanks of the pullers enables us to dispense with the links shown in United States PatentNo. 193,446, and making the slots in the shanks of thejaws is a better and cheaper construction than slotting the plate, and then providing each shank with a pin to enter such slots, as in United States Patent No. 193,445.

The tipping plate d is provided with a segmental bar, I, having ratchet-teeth, (see Figs. 3 and 4,) engaged by a pawhm, pivoted upon the hand-leverj, a link, a, and elbow-lever 0, also pivoted upon the said handle, being employed to operate the said pawl to removeit from the ratchet-teeth when the puller or jaw O is tobe retracted, a suitable spring, 1), so holding the pawl m as to engage the ratchet-teeth of the said bar I as the puller G is being moved forward, thus preventing the return of the lcverj until desired.

The lever 0 and pawl in may be moved by closing the hand on the handle of the hand-lever j.

The tipping plate (Z may be tipped by the screw 1", fitted into the end of the rigid arm 8, attached to the upper end of rod f, to enable the pullers or jaws O to'be placed in proper position with relation to the spring or curvature of the toe or heel of the last D at its bottom. The rack of the rod f is engaged by a sector, It, on a short shaft, 40, (see Fig. 2,) provided with a hand-lever, a, having a pawl, o, engaging a ratchet-bar, much as in United States Patent No. 208,127.

The sleeveg is mounted on a carriage, G, (see Figs. 1 and 4,) and is made horizontally adjustable by a screw, H, having a suitable thumb-nut attached to it, the said screw being so held by a cross-piece of the head A that it cannot be moved horizontally as it is rotated.

pullers G with the same letters used to designate like parts in connection with the toe pullers orjaws (3, adding, however, to said letters the prime-mark. Thus I) and b are like devices.

The shank and ball pullers, which engage the upper along the shank and ball of the last, and their operative devices, are substantially alike; so in describing them we shall use for one set second powers of certain letters, and for the other the third powers of the same letters.

The toe-rest I has its shank J (see Figs. 1 and 5) fitted to slide vertically in grooves of the upright part of the carriage a and made vertically adjustable therein bya n adjusting device, 15, (shown as a screw.)

The last-holding heel-pin, (shown in dotted lines, Fig. 1,) entered into the last D,forms part of an internally-threaded sleeve, 16, fitted to the upper end, 17, of aright-and-left-hand adjusting-screw, 17 19, provided with a collar, 18, the lower end of the said adjusting-screw being entered into a longitudinally-adjustable block, 20, below the under side of the longitudinally-movable carriage a The carriages a and a are bored longitudinally and threaded to receive the right and left threads of the long screw M, having the thumb-nut 22, the said screw being employed to simultaneously adjust in opposite directions the said carriages a? a carrying the toe-rest and heel-pin. The screw M is fitted loosely to the carriages G G, as shown in Fig. 10 by the carriage G.

The shank-puller is composed of a shank, 12 having a shoulder to receive against it one end of a spiral spring, 0 the shank having at its frouteud the pivotedjaw i provided with teeth j and the presser foot 70, substantially as in United States Patent No. 208,127. The shank is extended through a sleeve, d secured in the hollow headf ofa swiveling and adjustable pin, 9 A sleeve-nut, 0 inserted in the sleeve d a ainst one end of a s irin kee s the shank-puller pressed outward with more or less force, the said shank entering the sleeve d and compressing the spring 0 when the strain exerted by the shank-puller on the material in the shank of the shoe is too great. The stems 9 enter split sockets at the upper ends of carrying-arms l m and are adj ustabl y held therein by the screws h The arms I m are pivoted at their lower ends upon arms of a vertically-adjustable slide, n having a dovetailed projection, 0 (see Fig. 1,) fitted into a dovetailed recess in the vertical portion 19 of the carriage a the said slide and connected arms and shank-pullers being vertically adjustable by means of the elbow-lever r one arm of which (see Figs. 1 and 7) is extended under the said slide and a screw, 5', carried by the other end of the saidelbow'lever, the end of the said screw bearing against the edge of the upright 19 The arms Z m are joined operaend, withrack-tceth to be engaged by a sector, 14?, on a suitable shaft, o having a handlever, 10 secured to it, the teeth of the bar 15 being kept down in engagement with the sector by a spring, 25. This hand-lever has a pawl, A (see Fig. 7,) connected by rod B with the elbow-lever C operated by a spring, E the said lever O and spring enabling the pawl A to he lifted from engagement with or permit it to engage a ratchet-toothed sector, like that marked 26 in Fig. 4, that sector, however, being the one with which the like pawl, A of the hand-lever 20 of the ball-puller portion engages. As the hand - lever 20 or 20 is turned to move the sector like 21 one for each handlever, the said pawls A or B in engagement with a ratchet like that marked 26, will retain the hand-levers and arms of the shank and ball pullers in the positions to which they have been brought by the said hand-levers.

The ball-pullers, which engage the material of the shoe in advance of the shank-pullers, (shown in Figs. 3, 7, and 8,) have been constructed to move somewhat toward the toe of the last, to thus take up the slack in the material in the shank of the upper. To accomplish this novel resultthe heel-pullers (shown separately in Fig. 9) havetheir toothed portions '5 and presser k attached to a block, 28, mounted to turn a little horizontally on a vertical pivot, 29, inserted into the forked forward end of the shank b the said shank being rccessed to receive a screw, 30, the normal position of which is to keep the head 28 pressed out, as in Figs. 4 and 9. The forked forward end of the shank b also serves as a guide for the laterally swinging toothed puller and presser i g The slide n which carries the arms Z m (see Fig. 4) for the ball-pullers, is adapted to be adjusted vertically on the upright part f of the carriage (1 which also carries the toe-rest, by means of the screw 8 carried by a lever like that marked 1*, it o erating as does the lever r.

The pawl-and-ratchet contrivance, in connection with the hand-lever for operating the toe-pullers 0, enables the latter to be held in the position at which theyare left by the said hand-lever Rotating and tipping the head enables the operator, in lasting a shoe, to bring the same in front of him in just the desired position both when pulling over the upper and tacking or nailing it in place upon the usual inner sole on the last.

We claim 1. In a lasting-machine, the horizontally-rotating collar and head pivoted thereon, provided with the toe and heel pullers or jaws, combined with the stationary base, the adjusting devices to regulate the inclination of the head when tipped, and locking device to hold the head in horizontal position, substantially 5 as described.
