LAST.

SPECIFICATION forming part of Letters Patent No. 612,481, dated October 18, 1898.

Application filed October 11, 1897- To all whom it may concern:

Be it known that I, GEORGE l-I. CLARK, of Boston, countyof Suffolk, and State of Massachusetts, have invented an Improvement in Lasts, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings representing like parts.

This invention relates to lasts for boots and shoes upon which the boots and shoes may be lasted, and thereafter, while the last still remains in the boot or shoe, the latter may be subjected to whatever steps or processes desired in their manufacture, and, finally, while yet remaining in the boots or shoes, may be used as trees upon which the boots or shoes may be treed. i

The last forming the subject-matter of my present invention is intended as an improvement upon the last shown'and described in my application, Serial No. 630,370; and the construction of the last in many particulars, better adapting it to withstand the hard usage to which it will be put and also adapting it to be used in a boot or shoe having its waist measure less than its ball measure.

In accordance with this invention the last comprises, essentially, a fore part and a heelpiece hinged together and having a V-shaped opening between them, and the heel-piece is preferably made of metal and formed with an opening at that side which abuts against the fore part, and at or near the bottom of said opening a cross-pin is secured, which receives upon it the leaf or member of a hinge which is attached to the fore part, said pin thereby constituting the pintle or pivot-pin of the hinge. The heel-piece also has at its lower end and projecting from its abutting face a lip or flange, which overlies the shank end of the fore part, said lip or flange better enabling the last to withstand sudden and severe shocks to which it may be subjected.

The fore part is split in two or more pieces or sections, which are connected together by suitable sliding connections, the line or lines of severance being so located as to separate tion, and the hinge by means of which the heel-piece is connected with the fore part is the shoe.

attached to said instep portion, so that as the Serial No. 654,789. (No model.)

heel-piece is withdrawn the instep portion which is connected thereto will follow it and finally the remaining portion or portions of \vided whereby the split fore part and the piece are connected. together, and said engaging device is adapted to be engaged by any usual last-hook to withdraw the last from The engaging device is also preferablyconstructed so as to draw the instep portion of the fore part and heel-piece toward each other to thereby, relieve the pressure at the ball and heel when withdrawing the last from the shoe, and said engaging device is also preferably constructed and arranged to serve as a means of holding the several parts of the last in their proper relative positions in the shoe-t. 6., it is adapted to serve as a rear stop for that part of the split fore part to which it is attached and as a front stop for the heel-piece, and a rear stop is provided for the remaining portion of the split fore part, and said engaging device while serv ing as stops for the parts to which it is con nected, holds said parts so as to make said rear stop for the remaining portion of the split fore part effective.

Figure 1 shows in longitudinal section a last embodying this invention. Fig. 2 shows a perspective view of the heel-piece of the last.

The fore part, as herein shown, comprises the instep portion a and a sole-piece b, separated on a line of severance 2, said sole-piece b comprehending the toe of the fore part. These Idesire it to be understood, however, that instead of forming the split fore part in two parts, as a and b, it may be formed of any number of parts which may be deemed desirable, and, furthermore, instead of locatingthe line of severance 2 as herein shown, whereby the instep portion is removed from the sole-piece, said line of severance may be otherwise dis be withdrawn first and the remaining portions Q will follow.

0 represents a heel-piece, and it is made of suitable size and shape, and, as herein shown, it is composed of metal and is formed at the bottom of its abutting side or face with a projecting lipor flange c, which overlies the 1 shank end of the fore part. The heel-piece c is formed on its abutting side or face with a vertical recess 0 and at the lower end of said recess a cross-pin c is secured in the heel-piece, which receives upon it the lower end of a leaf or member d of a hinge. leaf or member d of the hinge is attached by screws or otherwise to the rear end of the instep portion of the split fore part, as herein shown in Fig. 1, and thereby connects the heel-piece with the fore part, leaving a V- shaped opening between them. A togglejoint 6 e is contained in said V-shaped opening at the top, which is composed of two levers jointed together and having their eX- tremities connected, respectively, with the fore part and heel-piece. e 6 when straightened out, as shown in Fig. 1, serves to hold the fore part and heel-piece separated, but is adapted to be engaged by a last-hook or other device, and when drawn out will operate to draw the heel-piece toward the fore part, and by thereby shortening the last will gradually and easily release and plizrmit easy withdrawal of the last from the s oe.

By connecting the heel-piece with the instep portion of the fore part it will be seen that as the last is withdrawn from the shoethe heel-piece is withdrawn first, the instep portion following it, and then the remaining part or parts of the split fore part will follow said instep portion.

It is obvious that many other ways of connection may be employed in lieu of the togglejoint herein shown for connecting the heelpiece and tore part together and having the function of holding said parts separated, and also for serving as an engaging device for a last-hook or equivalent when withdrawing the last from the shoe.

The split fore part herein shown may be withdrawn from a shoe having the waist measure less than its ball measure; but yet many other forms of split fore parts may be constructed which will enable the accomplishment of this result.

. A rear stop is provided for the sole portion 0 of the split fore part, which is herein shown as the rear end of the slotted plate 4, against which the T-shaped piece 3 strikes, or it may be the leaf d of the hinge, or it may be the lip c of the heel-piece, either one will sutlice, and the engaging device for the last-hoolgconsisting of the toggle-joint e 6, serves as a rear The- This toggle-joint stop for the instep portion of the split fore part and as a front stop for the heel-piece, and when thus employed to hold said'parts separated the rear stop for the sole portion 1) becomes effective.

I claim- 1. A last comprising a split fore part, the parts of which are connected together by a I sliding connection, and a heel-piece loosely connected to one of the parts of said split fore part, substantially as described.

2. A last divided transversely at or near the shank from top to bottom, and comprising a longitudinally-divided fore part and a heel-piece, and a hinge connecting said heelpiece with one of the parts of said divided fore part, whereby it may be moved relatively to said fore part in expanding or contracting the last, substantially as described.
