SHOE FORM v Filed June 4, 1942 INVENTORJ HLEERT E LEVHGG/ ATTO/R/VEVS Patented June 29, 1943 SHOE FORM Albert F. Levaggi, Brockton, Mass, assignor, by

mesne assignments, to Robert Channing Company, East Bridgewater, Mass., a corporation of Massachusetts Application June 4, 1942, Serial No. 445,693

3 Claims. (Cl. 12128.1)

This invention relates to shoe forms and particularly to those having a pivotal link or togglelike connection between a fore part or toe member and a rear or shoe heel-interior contact member. Particularly my novel forms permit of an all wood, no metal basis of structure, of very great importance under present circumstances.

As illustrative of shoe forms according to my invention, I show and describe a characteristic example. It is of simple structure, economical to manufacture, and very satisfactory in use. This showing is to be understood as illustrative and subject to modification within the terms of the appended claims.

In the drawing:

Fig. 1 is a general view of a shoe form in accordance with my invention, in collapsed condition as for entry into a shoe.

Fig. 2 indicates a longitudinal section through such a shoe in expanded condition in relation to a shoe as suggested in broken lines.

Fig. 3 is a section on the indicated line 33, of Fig. 2.

Fig. 4 is an indicated partial fragmentary section on the suggested line 44, of Fig. 2.

Shoe forms in accordance with my invention each comprise a front member or part I, a rear member or part 6, and a link or extension blade member 3 pivotally connected to the members I and 6. The link or extension blade member 3 and the member 6 establish a toggle that permits the shoe form to have various collapsed positions in which it may be easily inserted into a shoe and to be extended into its operative position in a shoe to display, condition; or maintain the condition of a shoe normally in use.

As one feature of my invention is that it provides a basis on which an efiicient, economical and attractive shoe form may be made without metal parts, I will describe it as an all wooden construction to emphasize its structural advantages.

The front member I may be considered as of contoured block origin preferably provided with a longitudinal slot l2 extending vertically through the member I thus affording ventilation. The rear face I of the member I is provided with a vertical kerf 2 extending from the upper part of the rear face I through the bottom of the member l to connect with the slot [2. The kerf 2 receives snugly the forward end 3 of the blade or link member 3 but permits the link member 3 as a whole freely to pivot in it. The end 3* of the member 3 and the fore part I are transversely apertured as at 3' to receive a pivotal interconnection, such as the dowel pint. The link or blade member 3 may be advantageously made of plywood or like stiffened stock, as indicated at P in Figs. 1 and 4.

' Iform the rear member 6 with a slotted interior 9 open on the bottom andfront, as at 9' and 9 respectively.

The rear part 3 of the link or extension member 3 has, adjacent its extremity, an aperture 3 to receive a pivot 8 entered through any one of the longitudinally disposed apertures I extending through the rear member 6 and aligned transversely of the slot 9. I employ a plurality of apertures l in order that the shoe form may be adjusted to fit any desired shoe by changing the position of the pivot longitudinally with reference to the rear part 6. The pivot 8 may be a headed pin turned from wood with its shank 8 having a friction fit in the apertures 1. As shown in Fig. 4, the end of the pivot may be tapered as at 8 to facilitate the centering and penetration of the link aperture 3 through the aperture 1 selected to establish the desired over-all length of the form.

The slotting of the rear part 6 leaves its rear end solid and the rear part is externally shaped to establish a slightly curved vertical contact area II] for the heel portion of the interior of a shoe to sustain the lining, counter and upper.

The rear part 6 constitutes a hand grip for guiding the form into a shoe and to facilitate this use of the rear part 6 I preferably form its top edge with a palm contacting curve I l terminating in a forwardly disposed horn or grip I l to facilitate the toggling guidance of the form into or out of its operative position in a shoe.

My invention provides for attractive, inexpensive and efficient shoe forms that may be easily extended into its operative position or collapsed by actuating the toggle established by the link or extension member 3 and the rear part 6. The forms may be easily adjusted to vary their extended length and may obviously be made of other materials than wood, if desired, when such other materials are available to the industry.

What I therefore claim and desire to secure by Letters Patent is:

1. A form to establish or maintain the desired condition of a shoe, comprising a solid contoured fore part having a vertical slot extending from the upper surface of the instep area through the bottom surface and continued completely through its rear face, a rear part having a slot open along its bottom and front faces, a link entrant of said slots and laterally sustained therein against part having a slot in its rear, a rear part having. a slot open along its bottom and front facesto.

define a longitudinally disposed bearing surface of substantial length, a link entrant of said slots,

a transverse pivot connecting the front end of said link to said fore part, said'rear parthaving a plurality of spaced transverse apertures in communication with its slot and disposed in aline in parallel with said bearing surface, a pivot disposable through any one of said apertures to pivotally interconnect the rear end of saidlink and said rear part, said link andv said rear part constituting a toggle and said rear part including a portion disposed intermediate said pivot manually engageable to actuate said toggle into and out of a positionwherein said form is extended into shoe supporting position, the portion of said link within said rear part slot having a surface in parallel and engageable with said bearing surface of said rear part when said form is in its opera tive position.

3. A shoe form comprising a contoured fore part having a slot in its rear, a rear part having a slot open along its bottom and front faces to define a pair of downwardly extending side walls and a bearing surface, a link entrant of said slots, a; transverse pivot connecting the front end of said.link to said fore part, said walls of said rear part having a plurality of spaced transversely alined apertures in communication with said rear part slot and disposed substantially in alinement with said pivot when said shoe form is in shoe supporting position, a pivot disposable through any one of said apertures to pivotally interconnect the rear end of said link and said rear part, said link and said rear part constituting a toggle and said rear part including a portion disposed intermediate said pivot manually engage able to actuate said toggle into and out of a position wherein said form is extended into shoe supporting position.
