SHOE FORM Filed Sept. l, 1957 Patented Jan. 3, 1939 UNITED STATES PATENT OFFlCE SHOE FORM tion of New York Application September 1, 1937, Serial No. 161,931

4 Claims.

This invention relates to an improvement in shoe forms and more particularly in a shoe form of the type which comprises an expansible toe member and a back part member. A shoe form of this type is illustrated in my Patent No. 2,067,- 381, dated January 12, 1937 and the present invention is a further development of such form.

In the operation of such a shoe form the toe member is removed from the shoe by a retractive force exerted upon it by the back part member. Such a force acts through the spring means which connects the sections of the back part member to compress them and hence is not positively applied.

The primary object of thisl invention is to provide in a shoe form of this type means whereby the retractive force exerted by the back part member is positively applied as by the provision of means through which the force acts directly upon the toe member.

A further object of this invention resides in the construction of the back part member whereby the spring is enclosed within a tubular rearward section which also receives one end of the forward section,

These and other objects will appear from a consideration of the following description and of the accompanying drawing which forms a part thereof and in which Fig. 1 is a view in side elevation of a shoe in which a shoe form embodying this invention is inserted, portions of the shoe and of the toe member being broken away;

Fig. 2 is a bottom plan View of the shoe form;

Fig. 3 is an enlarged view of a portion of the back part member, the tubular rearward section being shown in longitudinal section;

Figs. 4 and 5 are fragmentary views illustrating the relative positions of portions of the sections taken when the rearward section is advanced (Fig. 4)'and retracted (Fig. 5); and

Fig. 6 is a cross-sectional view taken along the line --i in Fig. 5.

In Fig. 1 of the drawing is shown a shoe I 0 having a toe and heel counter I2 in which a shoe form 29 is inserted. Such shoe form comprises a toe member 2| and a back part member 30.

The toe member 2| comprises a toe portion 22, having ball flanges 23, and a pair of crossbraces 24. Each crossbrace is pivoted at its forward end to a ball flange 23 and carries at its rearward end a rivet 25 which enters aV slot 26 in the other flange. The toe portion 22 is of Celluloid, buckram or other resilient formable material and the sides thereof are expanded or contracted by swinging the crossbraces from their forward pivoted ends.

The back part member 30 comprises av rearward tubular section 3| and a forward rod section 32, the section 3| receiving the rear portion of the section 32. Surrounding the rear portion of the section 32 is an extensible coil spring 33 secured at one end to the rear end of the section 32 and at the other end to a spool 34 carried by the section 32. The spool 34 comprises a head 35, a flange 36 adjacent the head and a flange 31 spaced fro-m the flange 36 by a collar 38. Formed in the flange 31 and collar 38 is a curved groove 39 which receives a loop 46 formed at the end of the spring 33.

In assembling the back part member the section 32 with the spring 33 is inserted in the section 3| through the open forward end thereof. The

flanges

33 and 31 of the spool 34 are of such dimension that they fit snugly in the section 3| and the head 35 closes the open end thereof. The spool 34 is secured in the section in any suitable way as for example by forming a. groove in the outer periphery of the flange 35 and punching a portion of the section therein. 'Ihus the forward end of the section 3| is substantially closed but since the section 32 is freely movable through the spool the sections 3| and 32 are relatively movable telescopically. The spring 33 yieldably resists that relative movement in one direction. Formed on the rear portion of sectionv 32 and within section 3| are ears 4| which are adapted to engage the spool and limit such relative movement in the otherl direction. The rear end of the tubular section is preferably closed and bent to form a loop 42.

When placing the shoe form in a shoe as shown in Fig. 1 the toe member 2| is inserted in the toe of the shoe and the section 3| pressed forward over the section 32 to contract the length of the back part member so that it can be inserted in the shoe with the loop 42 against the heel counter |2. The spring 33 acts through the sections of the back part member to hold the loop 42 yieldably against the heel counter and to hold the toe member in the toe of the shoe and expand the walls thereof against the walls of the toe. In removing the shoe form the section 3| is again pressed forward so that the back part member can be raised. The toe member is then contracted and removed from the shoe by drawing the section 3| back and exerting a retractive force through the back part member. As the section 3| is drawn rearwardly over the section 32 it rst acts thereon through the spring 33 and then acts directly thereon through the contact of the spool 34 and ears 4l. Thus the toe member is positively contracted and withdrawn without unduly compressing the spring 33.

While one embodiment of this invention has been shown and described, it will be understood that the invention is not limited thereto and that other embodiments may be made without departing from the spirit and scope of the invention as set forth in the following claims.

I claim:

1. A shoe form comprising a toe member and a back part member, said toe member being insertable in the toe of the shoe and said back part member serving to hold the toe member in position,l said back part member comprising a rearward tubular section and a forward rod section, the forward end of the rod section being `attached to the toe member and the rearward end thereof being received within the former section and the sections being relatively movable telescopically, a spring surrounding the end of the rod section within the tubular section and a spool surrounding the rod section and attached to the tubular section, the rearward end of the spring being attached to the rearward end of the rod section and the forward end of the spring being attached to the spool whereby the spring yieldably resists relative movement of" the sections in one direction.

2. A shoe form comprising a toe member and a back part member, said toe member being insertable in the toe of the shoe and said back part member serving to hold the toe member in position, said back part member comprising a rearward tubular section and a forward rod section, the forward end of the rod section being attached to the toe member and the rearward end thereof being received within the former section, and the sections being relatively movable telescopically, a spring surrounding the end of the rod section within the tubular section, and a spool surrounding the rod section and attached to the tubular section, the rearward end of the spring `being attached to the rearward end of the rod section and the forward end of the spring being attached to the spool whereby the spring yieldably resists relative movement of the sections in one direction and means for limiting relative movement of the sections in the other direction.
