Patented Apr. 5, 1938 2,113,295 UNITED STATES PATENT oFFlcE 2,113,295 SHOETREE Walter G. Downing, Vancouver, British Columbia, Canada Application November 14, 1935, Serial No. 49,788 2 Claims. (Cl. 12-128.1) This invention relates to shoe trees of the type employing wooden heel and toe portions operated by toggle links. Shoe trees of the foregoing type have been found to be especially well adapted to preserving the shoe last and thereby add appreciable com fort to the user of the shoe. However, various disadvantages have heretofore been inherent in such types of trees by virtue of improper adjust ment and alignment of its component parts. It is one object of my invention to provide an adapted to engage the rear face I4 of the tongue portion 3, the nut thereby being most convenient for accessibility and manipulation while the tree is positioned in the shoe. A pin I5 driven into the wood and through an opening in sleeve I2 @l holds the latter. My improved tree as above described permits automatic angular and axial alignment of the toe and heel portion as well as adjustment for length, merely by loosening nut I3 and rotating the heel 10 and toe portions relative to each other and then improved tree of the type above mentioned . inserting the' tree within the shoe and expanding whereby its eiîective length may be conveniently the same by pressing handle 'I down. Nut I3 may adjusted and maintained as well as effectively then be ñrmly screwed against surface I4 so as maintaining the heel and toe portions in proper to maintain not only the proper length adjust ment but also the proper angular and axial align ment of members I and 2 whereby it will be im possible with any reasonable usage to have heel angular and axial alignment. A further object is to accomplish the foregoing features by im proved means which is simple in construction, operation and maintenance without in any Way 20 encumbering or restricting the flexibility of the tree or causing annoyance to the user when ap plying the tree to a shoe. Other objects and advantages will be more ap parent to those skilled in the art from the follow 25 ing description of the accompanying drawing in which: Fig. l is a perspective of a tree embodying my invention; ' Figs. 2 and 3 are respectively transverse and 30 longitudinal sectional views through the toe por tion of the tree. In the particular embodiment of the invention which is disclosed herein merely for the purpose of illustrating one specific form among possible 3 Ul others that the invention might take in practice, I have shown in Fig. 1 wooden heel and toe por tions I and 2 respectively, shaped so as to sub stantially conform to the shoe last and provided with a raised instep element 3. The toe portion *0 is preferably hollowed as indicated at 4 in Figs. 4 50 2 and 3. A pair of toggle links 5 and 6 are piv otally connected together and one of the same is turned upwardly and curved to provide a ñnger loop 1. Link 6 is received within a suitable recess 8 tapered inwardly to a point adjacent a trans verse pivot pin 9. This groove permits the heel to be appreciably tilted to facilitate insertion of the tree in the shoe. Links 5 are pivotally connected as at I II to a bolt I l which as shown in Fig. 3 has threaded en gagement with a sleeve I2 suitably imbedded and secured in the instep portion 3. A simple wing nut I3 made preferably of plain ñat material 55 bent up at its ends is threaded on bolt II and portion I assume an undesirable angle in the shoe which if suchk should occur would cause probable injury to the shoe. The position of the nut andthe character thereof will conveniently and expeditiously permit such fastening operation to be performed, and this will be accomplished with the parts in most accurate relation as to 25 angularly, axial alignment and length. These will thereafter remain constant, regardless of the frequency with which the tree may be removed or inserted. From the foregoing disclosure it is seen that I have provided an extremely simple and yet highly effective tree for insuring maximum bene ñcial use with minimum effort or thought on the part of the user, consistent ‘with the assumption 35 of reasonable intelligence on the part of a user of a tree of this type which is especially adapted for shoes of high quality and style. It will of course be understood that various changes in details of construction and arrange ment of parts may be made by those skilled in the art without departing from the spirit of the in vention as set forth in the appended claims. I claim: 1. A shoe tree having wooden heel and toe por 45 tions, toggle links for moving said portions to and from each other, one of said links extending upwardly and being curved around to provide a iinger hold, means for pivotally connecting said linkage to said heel portion, a bolt adjustably 50 threadedly connected in said toe portion and hav ing pivotal connection with said linkage, and a nut on said bolt interposed between said pivotal connection thereof and said toe portion for en gagement with the latter to maintain said bolt in 55 2 2,113,295 ñxed relation to said toe portion and thereby pre tapered slot, a bolt adjustably threadedly cori-- vent rotation of the linkage and heel portion around the bolt axis. 2. A shoe tree having Wooden heel and toe por nected to said toe portion and having pivotal con nection with said linkage, and a nut on said bolt tions, linkage for moving said portions to and from each other, means for pivotally connecting said linkage to said heel portion including a Verti cally extending slot in the heel portion tapered inwardly from a forward face of the heel With 10 the pivot located near the deepest portion of said of and said toe portion for engagement with the latter to maintain said bolt in fixed relation to interposed between said pivotal connection there said toe portion and thereby prevent rotation of the linkage and heel portion around the bolt axis.
