SPECIFICATION forming" part of Letters Patent'No. 279,377, dated June 12, 1883.

Application filed April 19, 1883. (No model.)

To aZZ whom it may concern:

Be it known that 1, CHARLES EDWARD Goss, i of Lynn, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Attachments for Shoe- Lasts, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, m which similar letters of reference indicate corresponding parts in all the figures.

The object of this invention is to hold the block and insolein place when lasting shoes.

lasts, constructed with apertured base-plates, having projections upon their upper sides to receive betweenthem projections formed upon the lower sides of the top plates, which are slotted to-receive the heads, of the lockingkeys. In the spaces between the base and top plates are placed drivers having slots to receive the key and awl-heads, and projections to engage with the said heads, so that theforward movements of the keys will carry The invention consists in an attachment for the drivers forward and force out the awls, and the rearward movements of the keys will draw back the drivers and withdraw the awls. The keys are held in place, when pushed forward, by spring-catches, and the awls are held up by springs, as will be hereinafter fully described.

A represents a last, the top of which is cut away in the ordinary manner to receive the blocks B. In the last A, in the bottom of its out, are formed two recesses, G, into each of which is fitted aplate, D. In the face of the plate I), and longitudinally with the last A, is formed a wide groove, E, to receive the sliding plate or driver, and in the said face is formed a shallower groove, F,to receive the pr0- jections J of the top plate. The projections G, left in the angles between the grooves E F, serve as supports to the top plate. The top plate, H, has a wide groove, I, formed in its lower side, longitudinally with the last A, and the ends of the projections J, left at the sides of the groove I, are cut off, so that the said projections J will fit in between the projections G of the base-plate D, and thus center the plate H in place. The plates D H are secured in place by screws K, passing through theii-sideparts and into the last.

In the rear part of the plate H is formed a slot, L, the outer part of which is made of suf- 8o ficient width to receive the heads of the studs or keys M,,screwed into or otherwise secured to the block B. The inner part of the slot L is made narrower, so as to receive and fit upon the neck of the key M, while the head of the said 8 5 key is beneath the plate H, and thus holds the block B from -moving vertically and laterally, so that it cannot be moved out of place while lasting a shoe. v

To the under side of the plate D is attached 0 a small spring, N, having a projection, 0, upon its free end, which passes up through an aperture in the said plate D, in such a position as to be in the rear of the head of the key M to prevent the block B from slipping back 5 while in use. The rear and front edges of the head of the key M and the rear. and front edges of the projection O are slightly beveled, so that a rearward or forward movement of the block B will cause the key M to 'force 10 2 was down the projection O and allow the said key M to be drawn out and the block Bto be detached.

The last A has bevels P formed in it at the rear side of the recesses G to allow the key M to move back freely when the block B is being withdrawn.

Q is the sliding plate or driver, which has a slot, 1%, in its rear part, and a shorter slot, S, in its forward part, giving the said driver the form of two side bars connected a little in front of their centers by a crossbar. Upon the middle part of the side edges of the driver Q are formed narrow laterally projecting flanges T, which rest against the projections .T of the plate H, between the projections G of the plate D, and are shorter than the distance between the said projections G, so as to serve as stops to limit the movements of the said driver Q. The slot R is made of such a width as to receive the head of the key M, and at its outer end, upon the lower part of the inner edges of the driver Q, are formed projections U to enter recesses V in the ends of the head of the key M. The slot S is made of such a width as to receive the cross-head upon the upper end of the awl W, which passes down through a hole in the last A, so that its sharpened lower end can project to enter the insole placed upon the sole of the last. and prevent the said insole from slipping. The awl V is held up, leaving the sole of the lastA smooth, by a spiral spring, X, placed'in a countersink in the last A,with its lower end resting against the bottom of the said countersink and its up-.

per end resting against a cross-pin,Y, attached tc the upper part of the awl NV, and which also serves as a stop, by coming in contact with the lower surface of the plate H, to limit the upward movement of the said awl. The rear side of the top of the cross-head of the awl V is beveled, and the lower part of the edge of the driver Q, at the inner end of the slot S, is slightly beveled, so that the forward movement of the driver Qwill force the awl \V downward and into the insole and will hold it there until the said driver is drawn back.

Upon the lower part of the inner edge of the driver Q, at the outer end of the slot S, are formed projections Z, which are beveled upon the inner parts of their upper sides to engage with the lower beveled sidesof the ends of the cross-head of the awl TV, and withdraw the said a'wl from the insole. When the awl \V is raised the projections Z move back and forth without coming in contact with the cross-head of the said awl.

In using the provement, when the awls WV are. not to be used the toe of the last A is raised to allow the drivers Q to slide back, so that the heads of the keys M will enter the slots R in front of the projections U, and will not carry the drivers Q far enough forward to project the awls NV.

When the awls are to be used the toe of the last is lowered to allow the drivers Q to slide forward, so that the heads of the keys M will engage with the lugs U of the said drivers, and will carry the said drivers against the beveled upper ends of the awls W, and will force the said awls into the insole. As the block 13 is drawniback, in detaching it the projections Z of the driver's Q pass beneath the arms of the cross-heads of the awls W and raise the said awls out of the insole, and the heads of the keys M strike against inclined projections a, formed upon the upper side of the base-plates D, at their rear edges, and are raised so that they will readily pass out of the recesses G, in which the said plates D are secured. The withdrawal of the heads of the keys M is further facilitated by the inclined grooves I, formed in the last A, as hereinbefore described.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. An attachment forlasts, constructedsub stantially as herein shown and described, and consisting of the apertured base-plate D, the driver Q, having slots R S and projections U Z, the top plate, H, having slot L, the key M, having grooves V, and the awl V and spring X, as set forth.

2. The combination, with the last A and block B, of the base-plate I), having projections G, the top plate, H, having projections J and slot L, the key M, and the springcatch N O, substantially as herein shown and described, whereby the said block will be securely held in place upon the last, as set forth.

3. The combination, with the base-plate D, the top plate, Q, having slots R S and projections U Z, and the awl V and spring X, substantially as herein shown and described, whereby the forward movement of the said key will project the awl and the rearward movement of the said key will withdraw the ,awl, as set forth.
