June 13, 1939. c, JoHNsoN COMBINATION SHOE LAST AND PRESSER Filed Nov. l2, 1936 ZZ////////1 l INVENTOR. ff/pmx.: Jal/mmf Patented `lune 13, 1939 UNITED STATES PATIENT OFFICE 2 Claims.

l operating with a last which is stationary, the flexibie presser member will exert upon the sole, at specified locations, a different pressure than over the rest of the sole; with the result that the presser member will mark the sole or impress its shape in the sole at their points of excessive pressure. This is due to several reasons. The leather from which the sole is made may be possessed ofV uneven thickness, the last upport may be slightly tilted er the last itself may be so constructed as lo not to sit squarely upon the last support, with the result that the shoe is elevated at a certain part.

It is an object of the present invention to overcome these difficulties and to provide a last, so

arranged and constructed, that when cooperating with a flexible sole pressing member, the shoe may be permitted to move so as to meet the presser member equally throughout the area of the sole, thus resulting in equality of pressure upon the sole throughout its area. This is accomplished by permitting the shoe to move after it has been mounted on the last and in the present invention the movement takes place between the last and the mounting, although it will appear obvious from the description that this movement might also take place within the mounting itself.

Another object of this invention is to provide a last which is simple in structure, economical of manufacture, durable and highly eiiicient in use.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing, which forms a part of this specification and in which:

Fig. 1 is a side elevational view of the invention with associated parts showing parts broken away and parts in section. l

Fig. 2 is a sectional view taken on line 2-2 or Fig. 1. l

Fig. 3 is a fragmentary plan View of the pressing element used in the invention.

In the drawing I have illustrated the invention 'used with an apparatus comprising a standard 9, projecting upwardly from a base I0 and serving as a support for the table I I. Swingably connected to a lug I2 on the base Ill, is a pedal I3 connected to which, intermediate the ends thereof, at one end, is a rod I4, which extends thro-ugh 5 the table I I and into a sleeve I5 and connects to the rod I6, on which is mounted a heating hood Il, in which is positioned a heating element I8. Mounted on the open edges of the hood I1 is a flexible presser member I9, the ends of which 10 may be moved independently of the rest of the body by means of the lug 2U rocked by the member 2l. Aside from the presser member, the structure so far described forms no part of the present invention. 15 Projecting upwardly from a table II is a block 22 projecting upwardly from whichl are studs 23 and 24 adapted to engage in pockets formed in a last supporting arm 25. The last 26, upon which the shoe 2l is positioned, is provided on its under- 20 surface with a lug 28, engaging between the bifurcations 29 and 30, formed on the end of the supporting arm 25. A pivot pin 3| extends through these bifurcations and through the lug 28 to pivotally mount the last on the supporting 25 arm. When the shoe is placed in the position shown in the drawing and the sole, to be attached thereto, is laid thereon a downward pressure on the pedal I3 will move the flexible presser member I9 into engagement with the sole so 30 that the sole is clamped between the shoe and the flexible presser member I9. When the presser member I9 engages the sole, the shoe 21 on the last 26 is permitted to rock, so that the sole rocks to a position to meet the presser member I9 simul- 35 taneously throughout the area of the sole and adjust itself to the pressure exerted thereon by the presser member. In this way, the exerting of unequal pressure on any specific part of the sole is avoided and the impressing of the presser mem- 40 ber in any particular part of the sole is obviated. The combination therefore, of the flexible presser member with the movable last affords a means for avoiding the difficulties referred to and accomplishing the advantages mentioned. 45

It will be noted that the stud 23 is longer than the stud 24 and it will appear obvious, in mounting the member 25 in proper position on the block 22, the stud 23 may be engaged in its pocket and the last supporting arm 25 rotated on the 50 stud as an axis until the pocket or recess for reception of the stud 24 is brought into alignment therewith, whereupon the end face of the member 25 may bey moved into position to rest upon the block 22. n 55 While I have illustrated and described the preferred form of construction, I do not wish to limit myself to the precise details of the structure shown but desire to avail myself of such variations and notiiications as may come within the scope of the appended claims.

What I claim as new and desire to secure by Letters Patents is:

1. In combination: a. last supporting block; a pair of studs projecting upwardly from the upper face of said block one of said studs being longer than the other; a last supporting arm having pockets formed in one end for reception of said studs, said end of said arm being adapted for resting on said block, the opposite end of said arm being bifurcated; a shoe last; a lug proends for reception of said studs, said end of said arm being adapted for resting upon the upper face of said block; and a shoe last pivotally mounted intermediate its ends on the opposite end of said arm.
