SHOE- LAST.

SPECIFICATION forming part of Letters Patent No. 600,678, dated March 15, 1898.

Application filed August 25, 1 8 9 7.

To a, whom it may concern.-

Be it known that I, FRIEDRICH GUSTAV PABST, a subject of the German Emperor, and a resident of Hamburg, in the German Empire, have invented certain new and useful Improvements in Shoe-Lasts, of which the following is a specification.

The present invention has for its object an improved shoe-last-like implement which is designed to be placed inside a shoe in order to prevent changes or alterations'of the form of the shoe resulting from the influences of heat and moisture, thereby securing and preserving the proper shape of the shoe.

The improved shoe last or tree mainly conand a connecting screw-spindle hinged to the heel-plate and engaging a suitable nut journaled in the said fore part. In consequence of this construction and arrangement the last is capable of being adjusted in length in order to fit to shoes of different size. The insertion of the adjustable shoe-last into the shoe may easily be eifeoted by hand by applying only a moderate pressure. My improved implement is not to be confounded with the commonly-known shoe-stretchers, which are expansible lasts and serve for another purpose-viz., for expanding or distending a somewhat tight shoe.

To make my said invention more clearly understood, reference may be had to the accompanying drawings, in which- Figure 1 is a longitudinal vertical section of the improved shoe-last; and Fig. 2, a detailed View, on enlarged scale, showing the nut and a part of the screw-spindle.

Similar letters refer to similar parts throughout both views.

The improved shoe-last is composed of the proper last part a, made of any suitable material and shaped according to form of-the foot; of the heel-plate d, having the form of a shoe-horn and being provided with a handle or ring (1, and of a threaded rod or screwspindle 1), connecting the heel-plate d with the fore part a. The rear end of the spindle Z) is hinged to the heel-plate cl at 61 while its threaded front end is screwed into a nut c, Fig. 2. This nut c has lateral arms 0, carrying suitable trunnions 0 with which the Serial No. 649,478. (No model.)

said nut c is journaled in the side walls of the preferably trough-shaped last a, as clearly shown by Fig. 1. By this arrangement and connection of the parts the screw-spindle b is not only capable of being turned in the nut o in either direction, but may also be moved or swung up and down, together with the heel-plate d, in a vertical plane, as shown by dotted lines in Fig. 1.

My improved shoe-last may be used in the following manner: After, by turning the screw-spindle b, the last or fore part a and the heel-plate d have been driven apart the proper distance, corresponding to the length of the shoe to be operated, the last a is put into the shoe and then the heel-plate d pressed down into the shoe, so as to bring the heelplate from the position shown by dotted lines into the position shown by full lines, Fig. 1. By this down movement of the heel-plate, which acts and rests against the quarter of the shoe, the last a is pressed forward in order to cause the upper of the shoe to snug to the said last a, so that the shoe is not distended, but only regains its proper shape and the appearance of a new shoe.

For facilitating the adjustment of the said improved shoe-lastthat is to say, the regulation of its lengththere is provided on a flattened part b of the screw-spindle b a scale whichindicates the foot'len gths in shoe-Incas ures, Fig. 2. I

The hollow or trough-shaped recess of the last a, must be of such form and dimensions that for the purpose of ready and convenient storage and preservation and for conveyance the heel-plate and the spindle may be put into the said recess or trough of the last a by turning the nut 0 about its trunnions in the proper direction, thereby bringing the whole implement into a compact shape.

Having fully described my invention, what I claim, and desire to secure by Letters Patout, is-

1. A tree for boots and shoes comprising a toe portion, a nut journaled in said toe portion a threaded rod engaging said nut, and a heel-plate hinged to the end of said rod, substantially as set forth.

2. A tree for boots and shoes comprising a shell-like toe portion, and a nut journaled in said toe portion, in combination-with a threaded rod adapted to engage the nut, and an adjusting-scale on one end and a heel-plate on the other end of said rod, substantially as described.

In testimony that I claim the foregoing as my invention I-have signed my name, in presenoe of two Witnesses, this 12th day of August, 1897.

MAX LEMOKE, MAX KAOUSPFF.
