SPECIFICATION forming part of Letters Patent No. l87,627,dated December 6, 1892. Application filed November 25, 1891. Renewed November 8, 1892. Serial No. 451,314. (No model.)

To all whom it may concern:

Be it known that I, ARTHUR MELVIN LEIGH- TON, of Port Townsend, in the county of J of ferson and State of Washington, have invented a new and useful Improvement in Adjustable Shoe-Lasts, of which the following is a specification.

My invention relates to an adjustable cobblers last, which is automatically adjustable IO to closely fit any size of boot or shoe, no matter whether it has a pointed or wide toe.

Referring to the accompanying drawings, which show perspective views of my invention, Figure 1 represents the last complete.

Fig. 2 shows the heel part detached from everything but the wood block A. Fig. 3 shows the catch which holds the last in place when putting it into a boot or shoe. Fig. 4 shows the spring which forces the last to any desired size. Fig. 5 shows the front part of the last with the pointed or wide toe that may be reversed without removing from the heel part, and Fig. 6 shows the reach that holds the heel part and toe part together and which 2 5 the toe part reverses on.

Referring to the several parts by letter, A shows the wood block, that enables the workman to tack and hold the last in place in the boot or shoe, or to hold a run-down counterin its original place while the boot or shoe is being repaired.

B is the front part of the last, showing at its opposite ends the two toes. This part is provided with a longitudinal slot a, and be- 3 5 neath this a square recess, allowing the round cross-bar b of the reach D to pass through the longitudinal slot into the square space, and when turned lengthwise to lock the whole last together. This also forms a hinge, allow- 0 ing the last to be put into a boot or shoe the same as the human foot is inserted, and therefore does not strain the upper of a boot or shoe or change the shape already formed.

C shows the iron heel part of the last with the heel cast hollow, with the front part fitted to the shape of the reach D, allowing said reach to move freely. These parts are ex panded by the steel spring (1, which is wound about a stemfat the rear end of the reach. WVood block A has a hole a size larger than the spring, which hole when thelast is coupled holds the spring. When thelast is extended, the stem, which is a part of the reach D, guides the said spring.

0 shows the catch fastened with a loose rivet to the side of the iron heel Ofor the purpose of locking the spring in the wood block A while the last is being inserted in the boot or shoe. By pressing said catch on the outside of the boot or shoe the spring is released 50 and the last then completely fits the boot or shoe, ready for the workman.

By means of the hinge formed by the crossbar 1) between the heel and toe part the workman may allow the heel part to dropdown perpendicularly between his knees, and the toe part can then be used as a lap-iron to temper his leather on.

From the foregoing description, taken in connection with the accompanying drawings, the construction and advantages of my invention will be readily understood, and it will be seen that my automatically-adjustable last is very strong and simple and readily adjusts itself to fit different sizes of'boots or shoes.

By making the lasts in three sizeslarge medium, and small-allsizes of shoes that are ordinarily used can be repaired thereon.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, with the toe and heel sections in an adjustable last, of a reach-bar connecting the two and provided with alocking-notch, a spiral spring wound around a portion of the reach-bar and adapted to bear at one end againstthe heel portion andat the other against the reach to force the toe and heel parts away from each other, and a piv- 9o oted catch 0, fulcrnmed to the heel-section and adapted to enter the notch of the reach to lock the parts together against the tension of the spring while inserting the last in the shoe, substantially as described.

2. The combination of the reversible toesection B, having slot a, the heel-section AG, in the notch of the reach, substantially as the reach D, having cross-bar b, stem f, and shown and described. a notch 0n the side, the spring 61, surrounding the stem and pressing atone end against ARTHUR MELVIN LEIGII'ION 5 the heel-section and at the other against the Witnesses:
