SHOE FORM Filed March 19, 1929 the back part wire from the heel counter and with footwear varying in length the back part wire should be longitudinally adjust- Patented Oct. 7, 1930 i UNITED STATES PATE NT OFFICE AUBURN, NEW YORK, A CORPORATION OF. NEW YORK s'non FORM Application filed March 19.1929. SerialNo. 348,256. x

This invention relates to an improvement in shoe forms, and more ,partlcularly 1n shoe forms of thetypewhich comprise a hollow toe form and a back part wire.

Such shoe forms are particularly designed to keep footwear plumped out or free'from wrinkles and the toe form is shell like in quality being usually and preferably of celluloid or other resilient thin material. The toe form is held in position in the footwear by the back part wire which rests against the heel counter and is removed from itsposition by disengaging exerting apulling force upon the wire.

In order to adapt these shoe forms to use able and the prima-ry object of this invention is to provide a back part wire having longitudinal adjustability and which acts as without danger ofseparating the Wire from the form.

Another object ofthis invention is to provide in such a shoe form a back part wire 2 which can be cadjustablysecureddirectly to the toeform so as to adapt it for use in shoes yieldingly bears against the heel counter of V the shoe to hold the toe form in place but of various. sizes. invention is to provide in such a'shoe form a back part wire whlch is so formed that 1t whichcan be used to exert a positive with drawing pull upon the toe form when the shoe form is removed from. the shoe.

WILLIAM J. DE WITT; OF AUBURN, NEW YORK, ASS IGNOR 'IO SHOE FORM CO. .INC., OF

The shoe. form here illustrated comprises.

a toe form 10 and a back part wire 11.- The ous flange as here shown. In order to hold the wallsd l of the form 10 at theproper position a cross wire 15 is provided, being pivotally securedto a pin 16 inthefiange 12 of one wall of the form and having a button 17 which enters a slot 18 formedin the flange 13 of the opposite wall ofthe form:

The slot 18 may have a plurality of suitably spaced recesses 19 which receive and posi- In the

flanges

12 and 18 are provided a plurality of holes 20 suitably spaced from one another to .whichthe back part wire 11 may be secured. The wire 11- is preferably bent upon itself to provide a loop 21 intermediate its ends, the forward ends being bent at acute angles 23 toward each other from the main body of the wire, each end including a portion 28, a coil 24 and a portion 25,andterminating in a tip 26 at right angles to the portion 25. .The tips 26 pass through one of the holes 20 in each flange and enter the angles 22 as shown particularly in Fig. 3. g 6

From the construction thus described it will be obviousthat the cross wire 15 is set in the slot- 18 to determine the width of the toeform and that form is first inserted in the Force isthen exerted .70 pp p on the wire 11, preferably at the loop 21,

causing the coils 24 to yield so. that there will be a continuous yielding pressure exerted The loop 21 is. then placed againstthe heel counter so that the wire will continueito exert such pressure.

The amount. of pressure and the effective length of the wire may be adjusted by select mg the proper holes 20 to receive the tips 126.. 7 When theshoe form is tobe removed. from the shoe the loop 21 is disengagedfrom the counter and a pulling force isexerted on the wire 11 which causes the portions 23jtoshift into contact with the forward faces of the tips 26, thus transmitting a direct pull to the toe form 10 and facilitating the removal of that form.

The embodiment of the back part wire shown in Fig. 4 differs from that previously described in that the end portions 31 of the wire 30 are bent at the angles 32 into loops 33 which surround the tips 34:. ii ith a wire so constructed it is obvious that the loops 33 will shift under either forward or rctractive force, into contact with the tips 534: which are held in the flange holes by coils 35 and the toe form (not shown) vill be positively lllSGiLQCl or extracted from the shoe.

The embodiment shown in 5 :t'unctions in the same way as and is similar to that shown in Fig. l, differing therefrom solely int-hat the loops 41 of the wire 40 comprise coils which completely enclose the tips which are held in place by coils 4:3.

in the embodiment shown in Fig. o the legs forming the body of the wire are crossed at 51 which is so close to the tips of the wire that the sections 5 L form ..g the angle 55 are approximately parallel. The tips 52 are held in place by coils 56 and the application of force either forward or retractive will cause the sections 53 or 5:1. to bear against the tips 52.

It will be noted that in each instance upon the application of retractive force portions of the wire .bear directly against the tips which enter the angles of the wire and are yieldingly held in the holes 20 by the coiis. Thus there is no tendency to tilt the tips and draw them out of the holes 20 but on the contrary the tips transmit to the flanges of the toe form a positive rearward urge.

Furthermore it will, he noted that the ends of the wire exert a downward pressure upon the flanges of the toe form and thus counteract any tendency of the shoe sole to curl upwardly, a. condition which takes place particularly in a pull over or a shoe with a very thin sole and which quickly destroys the appearance of the footwear.

lVhile certain embodiments of this invention have been shown and described herein I am not limited thereto since other embodiments might 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 flanged hollow toe form and a back part wire, the for ward ends of the wire being bent toward each other at angles to the body, terminating in tips and including coils intermediate said tips and angles, and the flanges of the toe form being provided with holes through which the tips proi ect into the angles formed at the cinder of the forward end-s with the body ofthe wire.
