JACK FOR SOLE-MACHINES.

SPECIFICATION forming part of Letters Patent No. 461,403, dated October 13, 1891.

Application filed September 8, 1890. Serial No. 364,222. (No model.)

To all whom it may concern.-

Beit known that I, GEORGE H. GoeswELL, of Bradford, county of Essex, State of Massachusetts, have invented an Improvement in Jacks for Beating-0ut Machines, of which the following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing likeparts.

This invention has for its object an im- [0 proved construction of jack, whereby the sole of a shoe While the shoe is yet upon the last on which it was last-ed may be beaten out or pressed into shape and the sole leveled.-

In accordance with my invention the jackstandard has a head provided with a guideway for two carriages, one carrying a toe-rest and the other a counter or heelclamp, and a last-holding pin. The said carriages are connected together in such manner that they may be moved toward and from each other in the said guideway according to the length or size of the boot or shoe being acted upon. The construction of the parts of the toe-rest is such that when the jack is adjusted for a 2 5 certain length of shoe the toe-rest is also au tomatically adjusted vertically to thus place the toe of the last in the proper position with relation to the form which acts on the sole of the shoe, the form and jack both moving in arcs of circles. The last-holding pin is made movable independently of the carriage which supports the counter or heel clamp, and the device for moving the heel-pin to jack, as it is called, the shoe into the counter or heel 5 clamp is so placed and made that it may be actuated automatically by the form as it comes into position to act on the sole of the shoe.

Figure 1 in side elevation representsa suf- 4o ficient part of a beating-out or sole-leveling machine embodying my invention to enable the same to be understood; Fig. 2, a partial left hand end view of the parts shown in Fig. 1; Fig. 3, a partial righthand end View of the same; Fig. at, a section in the line 0;, Fig. 1,

looking upwardly; Fig. 5, a detail of the carriage, having the last-holding pin and heelclamp; Fig. 6, a detail in section, showing the toe-rest, its carriage, and locking device. Fig. 7 represents my invention embodied in a solelocking machine.

Referring to the drawings, (see Fig. 7,) the spindle A, the segmental toothed lever D connected to it, the sole molding or pressing form E, the leg E, the toothed segment-lever E the shaft E the worms E and D, and the means to rotate the said shaft E to turn the .to the upper end of the spindle'A a head A,

having its upper side out out to leave a guideway in which may fit and slide the carriages B and O, the said head having suitable slots,

as a a, through which are extended, respectively, the shanks b c of the said carriages, the said shanks having connected to them, respectively, the rack-bars b c, which mesh with a common pinion d loose on a stud at the under side of the head, (see Fig. 4,) the said racks engaging the said pinion at opposite sidesof its center, so that in case either carriage is engaged by hand and moved in the said guideway the other carriage will be moved in unison with it for a little distance, but in an opposite direction, the said carriages being so made movable in order that the jack may be quickly adapted to lasts of the size to be used.

The carriage B has erected upon ita 1101- low post I) in which is dropped a locking device b (shown by dotted lines Fig. 1, and separately in Fig. 6,) the lower end of said locking device being wedge-shaped torest on the teeth of alocking-block 12 said teeth having inclined backs and being so located that the locking device may slip over the said teeth when the carriage B is moved toward the spindle for a'shorter length of shoe, the looking device dropping behind the teeth and preventing the movement of the said carriage 5 in the opposite direction when the sole is being pressed.

The carriage B, by me called the toe-rest carriage, receives the shank of the toe-rest b suitably shaped to conform to the shape of ICC the top of the last. As herein shown, the shank of the toe-rest is terminated by an adin Fig. 6, into which maybe pushed awedgea toe-rest-lifting device.

shaped lifting-pin ewhenever it is desired to lift the lower end of the locking device 19 above the teeth of the block b, as when it is desired to pull the carriage to the right in Fig. 1, for a longer shoe.

The carriage 0, called the counter or heel clamp carriage, has erected upon it a counter or heel clamp 0 preferably rigid and of suitable shape to embrace the heel part of the upper. This carriage receives in it the slide-bar f, upon which is erected the-heel or last pin f, the said slide being normally held by the spring f slightly away from the said counter or heel clamp. This slide has a se ries of holes or notches 6, in which may be inserted the wedge-shaped lower end of the jacking bar g, adapted to slide vertically in a guidepost g, erected on the head A, the said bar being normally kept elevated by spiral or other spring 9 connected at one end to a pin 7 of the post and at its other end to a pin 8 of the bar. The head has pivoted upon it at 10 a lever 71, one end of which engages alifti'ng device 72, which when that end of the lever nearest the toe-rest-is lifted causes the lifting device to act on the pointed end of the jacking-bar, then down in a slot 6 and elevate it until the wedge-shaped part of the said bar is above the top of the slide f, when the spring 9 completes the movement.-

It will be noticed that when the toe-rest carriage is moved to the left, (see Fig. 1,) as is the case when a shorter last is to be used, the locking device is lifted, so that it acts as The inclined top of each tooth of the block b is a little higher than the one to the right of it in Fig. 1.

In operation, the last having on it a shoe the sole of which is to be beaten out or pressed or leveled to shape, is slipped over the heel pin f in usual manner, the operator having previously put the toe-rest carriage into the proper position for a last of the size to be used, the operation of putting the said toerest carriage in place also positioning the counter or heel clamp carriage and counter or heel clamp. The counter or heel part of the shoe touches, or nearly so, the counter or heel clamp. The machine will now be started and the spindle will be moved to carry the shoe to the left, viewing Fig. 7, and in so doing the jacking-bar will be depressed, so that its wedge-shaped lower end will enter one of thenotches 6 of the slide f anddraw the said slide and its connected heel-pin ff toward the counter-clamp, and so as to firmly crowd the heel of the upper into said counter or heel clamp, so that the last will be held rigidly while the usual form E acts on the sole. The jacking bar is depressed by a part of the form E or its carrier, as the form is about coming down upon the sole to be leveled, and the straight part of the jacking-bar above its wedge-point enters the notch 6 of the slide f, the bar in such depressed position firmly looking the said slide. I have described how the said bar may be lifted when the shoe is to be removed. In operation the same form will be used to beat out from 2 to7 size shoes; but forlarger or smaller sizes the form has to be changed, and as the'form and the spindle and last move in arc-shaped paths it is necessary that the toe-rest be at different heights, according-to the size of the shoe, the

smaller the size the higher the toe-rest, and

vice versa, so as to bring the toe part of the shoe correctly up into the form.

This invention is not limited to making the teeth of the block b of different height, and in practice it will be seen that one feature of the locking device and bar I) is to lock the carriages in adjusted position with relation to the heel-pin.

I claim- 1. In a j ack for a sole-beating-out machine, the spindle, the head, thelast-pin, and toothed block if, combined with a toe-rest carriage, a toe-rest, and alocking device intermediate the said toe-rest, and the said block, to operate substantially as described.
