To all tf1/omit may concern.'

Be it known that ITMILTON E. KREIDLER, a citizen of the United States, residing at Bethlehem, in the county of Northampton and. Sta-te oif Pennsylvania', have invented new and useful Improvements in Shoe Lasts, oi" which the following is a specification.

This invention relates to improvements in shoe lasts and the principal object of the invention to provide means for adjusting the last within the shoe so as to hold the shoeythe upper oi' the shoe.

The invention also consists in certain other 'features oil construction and in the combination and arrangement ot the several parts, to be hereinafter fully described, illustrated in the aeeoimoanying drawings and specifically pointed ont in the appended claim.

ln describing niv invention in detail, ref-1 crence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views. and in which Figure 1 is an elevation. of the last constructed in vaccordance with my invention and showingthe same expanded.

Figure 2 is a longitudinal section showing the last contracted.

Figure 3 is a plan view.

Figure t is a horizontal section.

Figure 5 is a section on line 5-5 of Fig ure 2.

Figure 6 is a like section but showing the parts in a different position.

Figure 7 is a section. on line 7-7 of Figure l.

Figure 8 is a longitudinal section. through the gear supporting brackets.

Figure 9 is a sectional view through one of the worm gears.

`Figure 10 is a view of the wrench for use with the device.

In these views 1 indicates the heel part of the last and 2 the toe part. overlap each other.. as shown, and the overlapping part of the toe portion is provided with a groove 3 for receiving the wrench engaging end 4 of the rotatable shaft 5 carried by the heel part. Theheel part is These parts provided with-an angle bracket 6 which carries said shaft. The vertical part of this braclret carries a screw-threaded shaft 7 and the two shafts are lgeared together'by the bevel gears 8. A'plate 9 is secured to the lower vertical `face of the'toe part 2 and this plate is provided with a screw threaded socket 1() for receiving 4the shaft 7.1 The bracket G also carries a guiding part 11 which engages an opening in the plate 9 :for guiding the two partsl of the lastin their movements. A

ltwill thus be seenithat `when the shaft 5 is rotated, by. means of the wrench 12 shown in Figure i0-, the screw threaded shaft 'T will also be` rotated and-the engagement of its threads with the screw threaded socket 10 will cause the two parts of the last to be moved relative to each other and thus the last may be expanded or contracted in the shoe. The slot 3 in the overlapping part of the portion 2 will permit this overlapping part to pass by the end l of the shaft so that the two parts of the last may be brought together'. This slot is large enough to permit the entrance of the wrench.

A bow-shaped platerlB is carried by the toe part 2 ot the last and this plate embraces the upper portion thereof adjacent the toe. This plate is verticallvmovable so `that it may be used for stretching vthe upper of the shoe and in order to niove this plate l provide the same with af pair of screw threaded studs 14 which project downwardly from its inner wall. These studs engage the screw threaded hubs 15 of the gear wheels 16 and these gear wheels are carried by the U- shaped end of a plate 17, which is secured in.

a recess 18 formed in the part 2 of the last. The looped end ofthe plate is provided with the openings 19 for receiving the hubs of' the gears so that the said gears. are rotatably held between the two parts of the plate with the screw threaded studs passing, through said hubs as clearly shown in Figures 2, 5 and 6.

The gears 16 are engaged by the last gear ot a. train of gears 20, carriedby thefplate and this train of gea-ring is set in motion by the wrench 12 engaged by the square shank 21 of the shaft 22, rotatably mounted in the plate and carrying one of the gears. I prefer to oifset the inner end of the plate and to' place the first two gears on this offset portion so that these two gears are above the plane of the other gears with the second and third gears carried by the saine shaft. By this ineans the Shank ,21 is placed nearerthe top of the last so that it may be easily engaged with the wrench.

It will be'seen that when the shaft 22 is rotated by the wrench its motion will be i1nparted to the two gears 16 and thus the studs lll will be rnoved vertically to raiseor lower the carved plate 13.

l n'lay secure button-shaped members 23 t0 the Quteriace of said plate wherever desired to stretch :the shoe at these points in order to form recesses n the shoe to receive `the cornsl or other growths on the 4foot.

By my invention the last after being placed inthe shoe may 'be expanded to stretch the Vsame and to provide recesses to receive corne and the like. Y By the use of my device the shoes may be made to last longer `as wrinkles and creases can be stretched out of the shoe and the shoe may be made to assume its original shape after becoming wet.

It is thought from the foregoing description that theadvantages and novel features `01;' my'invention will he readily apparent.

I desire it to be understood that I may niake changes in the construction and in the combinationand arrangement of the several parts, provided that such changes fall within the scope of the appended claim. 3

What I claim is v A shoe last having arecess therein, a plate located in the recess and having its toe end of U-shape, a. toothed wheel having a screw threaded central opening located between the 3: limbs ol the U-shaped part of the plate, a

n testimony whereof I aix my signature.
