SHOE FORM Application filed April 16,

This invention relates to an improvement in shoe forms and more particularly to expansible toe forms made of resilient flexible material such as celluloid or the like which inserted into the toes of shoes plump out the material thereof.

The primary object of this invention is to provide means for expanding or contracting the side walls of the toe form comprising a cross brace pivotally secured, at one end, to one side wall and having, at the other end, a slidable engagement with the other side wall and resilient means which normally holds the side walls in the expanded condition.

A further object of this invention is to provide means to facilitate the removal of the toe form from the shoe, such means comprising the treatment of the rear edge of the toe form cone to prevent any retarding engagement of the toe form and shoe upper.

Other objects of the invention will appear from a consideration of the following description and of the drawings which form a part thereof and in which:

Fig. 1 is a side elevation with parts broken away of a shoe form embodying this inven tion;

Fig. 2 is a bottom plan view of the shoe form illustrated in Fig. 1 in the contracted position;

Fig. 3 is a sectional View taken along the line 3-3 of Fig. 1 illustrating the toe form and cross brace in the contracted position;

i and Fig. 4 is a view similar to Fig. 3 illustrating the toe form and cross brace in the normally expanded position. 7

The toe form 10 comprises a cone 11, the

side walls 12 and 13 of which terminate in ly connected to the cross brace intermedi- 1931. Serial No. 530,514..

ate its ends is a rod 23 here shown as a wire 24 covered by a tube 25 and attached to the cross brace by a pin 26.

When the cross brace 20 is swung upon its pivot pin 21 the pin 22 is forced to travel in the slot 16 and the side walls 12 and 13 are thereby expanded or contracted. It has been found desirable to have the side walls normally expanded and the cross brace in the po- SltlOIl shown in Fig. 4: with the pin 22 near-ergo the inner end of the slot 16- This result has been attained by the employment of a resil ient wire 30 looped at one end around the stationary pin 21 and having at the other end a hook 31 which is passed around a pin 32 fixed in the flange 15 in advance of the slot 16. The wire 30 is also coiled around the pivot pin 26 and as is apparent from an examination of Fig. 4t tends to hold the form in the expanded condition. The pins 21, 22, 26 and 32 are here shown as rivets but obviously other forms of pins could be employed. Under retractive pressure exerted through the rod 23 upon the cross brace 20 the cross brace is swung from the position shown in Fig. 4: to that shown in Fig. 3 thus contracting the side walls of the form against the urge of the resilient wire so that the form can more easily be introduced into or withdrawn from the toe ofthe shoe. 'As soon as the pressure is released the side walls will resume their normal expanded condition. The hook 31 allows the wire 30 to shift longitudinally when the form is expanded as will be apparent from a comparison of Figs. 3

and 4t- The contraction of the side walls of the form will cause the cone 11 to rise and when in a shoe, the cone contacts more closely with I the shoe upper and the rear edge of the cone will bind against the upper and impede the removal of the form. In orderto overcome his difflcu ty the upper rear edge of the cone is rolled downwardly and outwardly, thus providing transversely extending rounded 35.and an outwardly extending flange 36. flange may be grippedby the fingers of the operator to wit idraw the contracted form and the are being in contact'with shoe upper will facilitate its removal.

While one embodiment of this invention has been shown and described, I am not limited thereto since 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. An expansible toe form comprising a body portion including a cone having spaced side walls, a cross brace connecting said side walls and being pivotally secured at one end to one side wall and slidably secured at the other end to the other side wall so that the cross brace is pivotally movable between a position in which the side walls are expanded and position in which the side walls are contracted, and a resilient wire secured at one end to the pivotal connection of the cross brace and side wall, at the other end to the other side wall and intermediate its ends to the cross brace, said wire normally holding the cross brace in the first of said positions while permitting its movement into the second of said positions. i

2. An expansible toe form comprising a body portion including a cone having spaced side walls, a cross brace connecting said side walls and being pivotally secured at one end to one side wall and slidably secured at the other end to the other side wall so that the cross brace is pivotally movable between a 1 position in which the side walls are expanded and a position in which the side walls are contracted, a rod pivotally attached at one end to the cross brace and a resilient wire secured at one end to the pivotal connection of the cross brace and side wall, at the other end to the other side wall and intermediate its ends to the pivotal connection of the rod and cross brace, said wire normally holding the cross brace in the first of said positions while permitting its movement into the second of said positions.

' 3. An expansible toe form comprising a body portion including-a cone having spaced side walls which terminate in flanges one of v which flanges has an 'arcuate slot therein, a cross brace connecting said side walls and being pivoted at one end upon the unslotted flange, a pin carried by the other end of the cross brace and in engagement with said s'lot so that when the cross brace is swung upon its pivot the pin engaging the walls of the slot causes the side walls to expand or contract, and a resilient wire secured at opposite ends to the flanges and intermediate its ends to the cross brace, said wire normally holding the cross brace in a predetermined position while permitting movement into other positions.

, 4. An expansible toe form comprising a body portion including a cone. having spaced side walls which terminate in flanges one of which flanges has an arcuate slot therein, a

being pivoted at one end upon the unslotted flange, a pin carried by the other end of the cross brace and in engagement with said slot so that when the cross brace is swung upon its pivot the pin engaging the walls of the slot causes the side walls to expand or contract, and a resilient wire secured at opposite ends to the flanges and intermediate its ends to the cross brace, said wire normally holding the cross brace in a predetermined position while permitting its movement into other positions, one end of the wire being secured to the pivot of the cross brace and the other end being secured tothe slotted flange in advance of the slot therein.

5. An expansible toe form comprising a body portion including acone which when the form is insertedin the toe of a shoe engages the upper thereoit', the upper engaging surface of the cone terminating in a transversely extending rounded arc.

6. An expansible toe form comprising a body portion including a cone which when the form is inserted in the toe of a shoe engages the upper thereof, the cone having a rounded are adjacent its upper edge and terminating in a rearwardly projecting flange.
