EXTENSION SHOE-LAST.

SPECIFICATION forming part of Letters Patent No. 480,596, dated August 9, 1892.

Application filed July 13, 1891.

To on whom it may concerni- Be it known that 1, JAMES HOMER LIVER- MORE, of Port Townsend, in the county of J eflerson and State of Washington, have invented a new and useful Improvement in Extension Shoe-Last-s, of which the following is a specification.

My'invention relates to that form of last shown, for instance, in patents to Leighton, Nos. 407,080 and 407,081, in'which a heel portion is provided with an extensible toe or sole portion which is made reversible and is also adapted to be extended more or less, according to the size of the shoe, the same being especially designed for use in repairing.

It consists in the peculiar construction and arrangement of the parts, as will be hereinafter fully described.

Figure l is a perspective view of the entire last. Fig. 2 is a perspective view of the detached toe portion. Fig. 3 is a perspective view of the connecting-bar; Fig. 4, a perspective view of the heel portion, and Fig. 5 a view of the set-screwfor connecting the parts.

In the drawings, A represents the heel portion of the last, which is made, preferably, of cast-iron and is formed hollow with a crossbar a near its front end and a screw-holeb in the instep portion, which screw-hole is threaded to receive a set-screw. o. Extending through the open front end of the heel portion and resting upon the cross-bar a is a connectingbar D, also made of metal. This connectingbar has at its front end a downwardly-extended T-shaped head 6 and on its upper face has a series of graduations g and just back of these a series of screw-seats f to receive the point of the set-screw in the various adjustments.

B is the detachable toe or sole portion, which is also preferably made of metal and has in its center an elongated slot cl, with raised edges. The opposite ends of this portion B are made substantially alike, except that one is broader Serial No. 399,418- (No model.)

than the other to fit into the different styles of toe. Through the slot (1 is passed the T- shaped head 6 of the connecting-bar D, the part B being for this insertion turned at right angles to the bar, so as to let the head e pass through the slot the long way, after which the part B is turned back into alignment, which causes the ends of the head e to find a bearing against the under side of the portion B. I

The rear end of the connecting-bar D extends into the heel portion above its cross-bar a in a socket which closely fits the same, and into one of the seats f the point of the screw 0 is turned to lock the parts tightly together, so that they cannot slip apart or become dlsplaced. VVherethe graduations show beyond the front end of the heel portion the size of the shoe isindicated. With this construction it will be seen that the last may be adapted to any ordinary size of shoe, and either end of the toe portion may be used by simply reversing that section.

Having thus described my invention, what I claim as new is- 1. In an adjustable shoe-last, the combination of the reversible toe-section B, having an elongated slot d, with raised edges, and the connecting-bar D, having an offsetting or downwardly-extended T-shapedheade,adapted to be passed through the slot 61 when turned at right angles and to look under the same when turned into alignment, substantially as shown and described.

2. The connecting-bar D, having the T- shaped head 6, graduations g, and screw-seats f, in combination with the heel portion A, having cross-bar CL and set-screw c, and the reversible toe portion B, having the slot d, substantially as shown and described.
