' Specification of Letters Patent.

Application filed August-23, 1902. Serial No. 120,736.

Patented Deo..31,1912;

To all whom it may concern 1 3e it known that I, EDWIN L. GODING, a citizen of the United States, residing at Springvale, in the county of York and State of Maine, have invented an Improvement in Lasts, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention aims to provide a novel and improved last; one which shall combine the advantageous features both of the hinged last so called, and the older form of block last, without the disadvantageous features of either. 4 The nature of my invention will best be understood fro-m a description of a last illustrating one embodiment thereof, it being understood, however, that my invention -is not restricted tothe'particular embodiment disclosed.

In the accompanying drawing-Figure 1, Y

I in side elevation,shows a last illustrating with one or more forwardly extending plates or hinge pieces, d, pivoted at d, to the fore part. This pivot may be located at any desired point orlevel, but I prefer to locateit quite close to the bottom of the last and below the point at "which the last would sustain itself against collapse, thus to ob'- tain the maximum shortening of the last for a given relative swinging movement of the fore and heel parts.

The instep block, 0, as here shown, laps both the fore part and heel part, and when inposition, held by the upper lasted or laced above it, efi'ectually guards against accidental collapse of the last. The instep block, a, maybe secured in ositiorragainst sliding movement in either direction by any of the well known means. I prefer 'however, to give'to the secant line along which the said lnstep block is divided from the remaining body of the last, such a sweep or direction as shall present, at some poin t in its length, a slide resistinj "girface. In the last shown, this secant line is indicated at 1, said line being given a sweep at 2, to provide opposite locking or slide resisting surfaces which cooperate respectively with the looking surface 3, on the fore part, and 4 on the heel partto hold the said block firmly in position.

By forming the looking or slide resisting surfaces on the instep block, with sweeps or curves where they blend with the secant line of which they really form a part, I am enabled to divide the inste block from the remaining body portion 0 the last by a saw traveling throughout in one direction so that the formation of such looking .or slide resisting surfaces adds practically nothing to the cost of dividing the last at this point. A looking or slide resisting surface at 23, obviates the necessity for the usual pin at the toe end of the instep-block and the surface 24, likewise obviates the necessity for a spring looking or other pin or device at the top. end of the said block.

By. sliding the instep block upward, with or without turning it into its dotted position, Fig. 1, the waistmeasurement of the last may be reduced, as with the ordinary block last, which is desirable for the most ready withdrawal of the last from or.its

' insertion in a shoe. And the subsequent insertion of the block 'lls out the shoe across the instep in a manner peculiar to lasts of.

the removable block type and not always attainable in the ordinary hinge last having a solid fore part.

It will be noted that the instep block a is so proportioned and the surfaces 1 and 4 are so shaped that during the first part of the backward movement of the block the depth of the last from the shank to the instep engaging surface will be increased.

The last shown is so designed that this increase at the upper part of the ins'tep will continue until the corner at the right of the,1Q0'

step block in operative position without the employment of the usual locking devices Having removed the instep block, the heel tially the extent indicated in dotted lines,.

by contact of the front face of the heel partwith the rear face of the fore part, near thetop of the latter. This is useful in turn shoe work, as it enables the lasterto strike the last at its heel, upon the bench, and drive the fore part into position, as with the use of the ordinary block last. Obviously this could not-be done with the ordinary hinge last, which would at .once collapse if any attempt were made to drive it endwise into place, unless some special locking device Ivere used, which is unnecessary with my ast.

My invention is not restricted to the particular embodiment thereof herein shown and described, but may be varied without departing from the spirit and scope of said invention.

Claims:

1. A last comprising complementaryshaped fore part, heel part and instep part, the contacting surfaces of said parts being formed to resist collapse of the last.

2. A multipart last comprising relatively movable fore and heel portions and a slid-- able instep block having a slide resisting surface cooperating with the top and rear of said fore portion.

3. A last comprising complementaryshaped instep part and fore part, said instep part tapering to a thin edge at its forward end and a heel part movably connected to said fore partand in the operative position of the parts held from upward movement by said instep part, the contacting surfaces of said instep part and fore part being formed to resist downward movement of the instep part upon the fore part.

4. Aniultipart last comprising a fore part, a heel part, and an instep block presenting aways near the rear end of its secant face-slide and heel part resisting surfaces.

5. A last comprising a fore part, a heel part hinged to said fore-part near the sole. of the last, said lastbeing recessed at the upper region of juncture of said fore part and heel part, and an instep block for completing the instep portion of the last arranged to have. engagement in its operative position with the heel part and having a projection to enter said recess, the contacting surfaces of theparts being formed to resist relative movement of said parts.

6. A last comprising a fore part, a heel part movably connected to the fore part, and a removable block for completing the instep portion of the last having engagement in its operative position with the fore part and the upper portion of the heel part, said fore part and block having, upon their contacting surfaces intermediate the ends of the block, in-

terlocking portions extending from one side to the other of the last and formed to resist forward movement of the block.

7 A multipart last comprising fore and heel parts and an instep block provided with oppositely acting locking surfaces engaging the adjacent faces'of the fore and heel parts respectively;

8. A multipart last comprising a fore part and a heel part hinged together, and an instep block the secant face of which presents,

at points adjacent the junction of the fore EDWIN n GODING.
