' sHoE FORM Filed Dec. 2. 1929 Patented May 5, 1931 ori-ice I WILLAEI J. DE WITT, OF AUBURN, NEW YORK, ASSIG-NOR TO. SOI-IOEFORM CO., NC., O13` AUBURN, NEW' YORK, A CORPORATION OF NEW YORK SHOE FORM Application filed December This invention relates to a shoe form, more particularly to one of the type comprising a hollow toe member, provided with an adjustable cross brace and a back part wire secured to such brace, one illustration of which is given in Fig. 3 of my copending application Serial No. 327,399, filed December 20, 1928, patented December 9, 1930, No. 1,784,660.

One objectof this invention is to provide a shoe form of the above type in which the cross brace is provided with a coil intermediate its ends, which coil provides a longitudinally extending passage and to which the forward end of the back part wire is secured in such a manner that the lateral or pivotal movement of the toe form is restricted.

Other objects will appear from a consideration of the following specification taken in connection with the drawings, in which:

Fig. 1 is a side elevation of a shoe form embodying this invention;

Fig. 2 is a bottom plan view of such form on a. larger scale, a portion of the back part wire being omitted; and

Fig. 3 is a sectional view taken along the line 3-3 of Fig. 1.

The shoe form comprises a vhollow toe form 10, a cross brace 11, and a back part wire or stay 12 and is adapted to be placed in a shoe, the toe form entering the toe of the shoe and the back part wire bearing against the heel thereof indicated in dotted lines in Fig. 1. y1`he back part wire is thereby flexed and due to its tendency to return to its normal position it swings the cross brace forward, expanding` the walls of the toe form until prevented by Contact with the walls of the shoe.

The toe form is preferably, but not necessarily, made of resilient material substanv tiallv in accordance with the process outlined in my Patent No. 1,585,284, dated May 18, 1926. The

side walls

15, 16 of the toe form terminate in

ball flanges

17 and 18 re spec-tively, upon which iianges the form normally rests, as indicated in Figs. 1 and 3.

The cross brace 11 is pivotally secured at one end to the flange 17 in any suitable 2, 1929. Serial No. 410,942.

ner, as by means of a rivet or button 20', and has, at the other end', a sliding engagement with the flange 17. 1n the.l present instance the flange 17 ifs provided with an arcuate slot 21 adapted to receive a headed rivet or button 22 to the shank of which button the end of the cross brace is secured. Intermediate the ends of the cross brace is formed' a coil 23 consisting of one or more turns 24 providing a passage extending longitudinally in subtantially 'the plane of the body of the cross race.

The back part wire 12 terminates in a portion 25 at an angle tof the body portionV 26 and ak tip 27 at an angle to the portion` 25. Theportion 25 is passed through the passage defined by the' turns 24 of the coil 23, and the tip 27 extends upwardly, as shown particularly in Fig. 3. The body portion 26 passes above the cross. brace 11 sothat it normally rests uponl such cross brace. rl-he back part wire is provided at its outer end withy an offset loop. v28 which is adapted in the well known mannery to engage the heel counter of the shoe in which the form is adapted to be placed. It will be apparent that when the shoe form is placedv ina shoe the resiliency of the back part wire norm ally tends to swing the cross brace 11 around its pivotal connection with the flange 18, thus separating the

walls

15 and 16 of the form until checked by their engagement. with the walls of the shoe.

t wil-l be noted that the body portion 26 and the tip 27 of the back part wire, since they extend at angles to the portion 25, serve to-limit the lateralmovement of the toe form and to prevent any unwanted separation of the back part wire from the brace. It will be further noted that theV bodyA portion 26, being above the cross brace 11, limits the pivotal movement of the toe form relative to the back wire in one direction, and that this movement is limited in they other'direetion by the body of the form., as-will beobvious from a consideration of Fig. 1.

I claim:

1. A shoe form comprising a hollow toe form, a cross brace connecting the walls of said toe form, one end of said brace being pvotally secured.. to` one Wall of the toe form and the other end having a slidable engagement with the other wall of the toe form, a coil intermediate the ends of the cross brace forming a longitudinally extending passage and a back part wire terminating in a portion at an angle to the body thereof which portion is passed through the passage in the coil in the cross brace and by which the cross brace and back part wire are connected.

2. A shoe forni comprising a hollow toe forni, a cross brace connecting the walls of said toe form, one end of said brace being pivotally secured to one wall of the toe form and the other end having a. slidable engagement with the other wall of the toe form, a coil intermediate the ends of the cross brace forming a longitudinally extending passage and a back part wire terminating in a portion at an angle to the body thereof, and a tip at an angle to the portion, said portion passing through the passage in the coil of the cross brace, the body of the wire and the tip extending above the cross brace, thereby limiting any pivotal Imovement of the cross brace and toe form relative to the back part wlre.

3. A shoe Jform comprising a hollow toe form, a cross brace connecting the walls of said toe'form, one end of said brace being pivotally secured to one wall of the toe form and the other end having a slidable engagement with the other wall of the toe form, a coil intermediate the ends of the cross brace and a back part wire terminating in a portion at an angle to vthe body thereof, and a tip at an angle to the portion, said portion passing through the coil of the cross brace and the tip extending at an angle to the coil of the cross brace, thereby limiting any lateral movement of the cross brace and toe form relative to the back part wire in one direction.

4. A shoe form comprising a hollow toe forni, a cross brace connecting the walls of said toe form, one end of said brace being pivotally secured to one wall of the toe form and the other end having a slidable engagement with the other wall of the toe form, a coil intermediate the ends of the cross brace and a back part wire terminating in a portion at an angle to the body thereof, and a tip at an angle to the portion, said portion passing through the coil of the cross brace, the body portion and tip each extending at an angle to the coil 'of the cross brace, thereby limiting any lateral movement of the cross brace and toe form relative to the back part wire in either direction.
