This invention relates lto an improvement in shoe forms and more particularly in-expansible toe forms adapted to be insertedA into the toe of a shoe and expanded therein to 5 plump out the shoe and put it -in the ideal condition for display .orl other purposes,"y

Various types of such toe forms -have been proposed `and suggested heretofore and the object of the present invention is to .provide lc an improvement upon the means for expanding'and contracting the4 toe-form such `improvement including a crossbrace made vinto en being inserted into or withdrawn fromVA the Other objectsof` the-invention reside fr in the` provision of the; particular structural features set-,forth in the following descrip- 25V tion and illustrated in the accompanying drawings wherein y Y v Fig. 1 .is a sideelevation ,of a toe form embodying this invention; 9j. i

The bars` 16 andfl are preferably of Celluloid which-'10 may be laminated asv shown inFigs.l Land v5. The .shoulder 25 isformed on the upperlamina 30 which projects beyond thelower lamina -31 whilethe ledge 26 is formed bv thelower lamina 32 which stops short of' the upper'l lamina `33. Iherivet 20 extends through the

Yupper laminae

30 and 33. f Other ways of forming the-shoulder' 25 and thev ledge26 and of joining the barsmay of course be-.employed, those herein described having beenkvO` selected for the purpose of illustration and It will be. apparentthat when the retractor 21is pulled to the left in Fig. 1 the form f isrcontracted:k as in Fie. 3 until the ortion.85 Figs. 6 and 7 are views corresponding to t p n 26. The form is-nowK in condition to befinserted into or withdrawn from the toeof a expanded position illustrated in F ig.`2 with the portion 28 of the shoulder in` contact with `-the ledge 26.
