LAST.

Specification of LttersPatent.

Patented an. '7, 1919.

Application filed May 14, 191-8. Serial No. 235,041.

.zen of the United States of America, and

a resident of East Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Lasts, of which the following is a specification.

This invention relates to improvements in lasts used in the manufacture of boots and shoes, and particularly to that class of lasts that are divided transversely and areadapted to be shortened to facilitate the ready removal of the shoe.

The removal of a turned shoe from a last of ordinary construction is made with considerable difliculty, and to remedy this defeet and provide a last from which the shoe may be removed without difficulty is the object of the present invention.

The invention consists in certain novel features of construction and arrangement of parts which will be fully understood by and organized and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described, except as required by the scope of the appended claims.

Of the drawings:

Figure 1 represents a vertical section of a last embodying the features of the present invention.

Fig. 2 represents a similar section with the heel part moved relatively to the fore part in order to shorten the last.

.Fig. 3 represents a horizontal sectional detail on line 3, 3, on Fig. 1.

Fig. 4 represents an end view of one of the pintles.

Fig. 5 represents a transverse section of a pintle on line 5, 5, on Fig. 3 and Fig. 6 represents a plan of a pintle.

In the drawings, 10 is the fore part and 11 the heel part of a last transversely divided on the inclined line 12, 13, extending downwardly from the point 12 intermediate the comb l4 and heel end of the last and forwardly toward the toe end 15.

Before dividing the last on the line 12, 13, a cylindrical hole 16 is bored into the same from the bottom ofthe last, the axis of said hole being onthe line of 12, 13, so that when divided the adjacent faces of the heel and fore parts will each have therein a semicylindrical groove.

. In the fore part 10 are mounted two parallel pintles 17, 18 anchored in said fore part by means of a pin. 19. Similarly mounted in the heel part 11 are two pintles 20, 21 anchored in said he'el part by the pin 22.

j Each pintle 17, 18, 20 and 21 is provided with a transverse groove 9 therein leaving a fiat face at the top whichfacilitates the boring through said pintles of the transverse holes to receive the anchor pins 19 and 22.

The pintles 17, 18, 20 and 21 are all positioned in holes bored into the fore part 10 and heel part 11,. and then the holes to receive the anchor pins 19 and 22 are bored into the fore part and heel part and through the pintles positioned in said parts and then the anchor pins 19, 22 are inserted, thereby securely locking said pintles in position.

Each pintle 17, 18, 20 and 21 is provided with a flat sided ear 23 having an opening 24: therethrough to receive a rod 25, said rod extending through the openings 24 in all of the pintles and retaining the adjacent faces of the fore part and heel part in contact at all times.

The ears 23 of the pintles 20, 21 are respectively beneath the ears of the pintles 17, 18 and are normally held in contact therewith by the helical spring 26 surrounding the rod 25 and interposed between the upper pintle 20 in the heel part 11 and the lower pintle 18 in the fore part 10.

The ears 23 of the pintles 17 18 extend into the vertical groove in the front face of the heel part 11 and the cars 23 of the pintles 20, 21 likewise extend into the groove in the rear face of the fore part 10.

The openings 21 in the cars 23 are all in alinement and in the plane of the transverse part 11.

In the upper end of hole 16 is placed a semi-cylindrical plug 27 and secured to the fore part 10, this plug 27 bearing against the upper end of the rod 25 thereby preventing upward movement thereof.

Beneath the lower end of said rod is positioned a pin 28 driven into the fore part 10 and preventing any downward movement of said rod.

The spring 26 between the pintle 20 and 18 normally retains the last in extended position as shown in Fig. 1. As soon as it is desired to shorten the last the parts 10, 11 are moved relatively to each other into the position shown in full lines in Fig. 2 and the last is immediately shortened in an obvious manner.

By varying the inclination of the dividing out between the parts 10, 11, the degree of shortening will be varied.

The heel part 11 is provided with the usual pin socket 29 by-which the last is supported on the usual supporting pin during the lasting operation.

' It is obvious that by this construction of last all upward movement of the heel part ll relatively to the fore part 10 is prevented, the parts of the last being retained normally in extended position by means of the spring 26, and when it is desired to shorten the last while placing a shoe thereon or removing it therefrom, the fore part will be moved toward the top of the last in the direction of the arrow it against the tension of the spring 26 which will return the parts to their normal position as soon as all outside pressure has been removed.

This makes a very simple construction of last, easily manufactured, and very effective in operation.

It is believed that the operation and many advantages of a last thus constructed will be very apparent without further description.

Having thus described my invention I claim 2' l. A transversely divided last consisting of a fore part and a heel part divided on a line'inclined downwardly; a pair of pintles in each part extending toward the other part; a rod extending through all of said pintles; and a spring surrounding said rod between two pintles, one of which extends from each part.
