7 Claims. (01. 12-4282) This invention relates to shoe trees and isherein illustrated as embodied in a tree of the type in which the toe piece is divided into two parts adapted to be spread apart laterally to fill the forepart of the shoe.

It is desirable, in order to avoid making many sizes of shoe trees, to have the toe piece divided longitudinally so that the two parts may be spread laterally the better to fill and tree the forepart of the shoe, thus enabling its utilization with shoes of widely varying widths. Com,- monly, the two parts which make up the toe piece are held together by screws or the like on which one of the parts is slidably mounted and the heads of which serve to limit the lateral movement. Under present restrictions, however, the use of metal in shoe trees is limited to a very small part'of the total material employed, and it becomes necessaryto devise a construction which may readily be made out of wood or some equivalent material. It will-be understood also that shoe trees of this type will be sold for use in shoes having low heels as well as in slices having high heels. Some of the shoes will have straight lasts and others will have a decided swing.

In view of these considerations, it is an object of the invention to devise a simple shoe tree construction which will be salable for use ina wide variety of shoe styles and which needs only to be made in a few sizes, thus avoiding the necessity for the retailer to maintain a large stock.

To this end, the spreading of the parts of the toe piece is accomplished by means of a loose spreader, illustrated as a wedge received in grooves in the inner faces of the two halves of the toe piece, and these grooves are inclined downwardly and forwardly. Further, in accordance with a feature of the invention, the connector between the heel piece and the toe piece acts as a thrust bar to push the wedge forward but is entirely disconnected therefrom and may be brought into engagement with the wedge in any style of shoe regardless of the height of the heel or the swing of the last by reason of the fact that it is slotted to surround one of the screws which holds the parts of the toe piece for limited spreading movement and because of the fact that it has a rounded forward end to engage the back ed e of the wedge.

These and other features of the invention will best be understood from a consideration of the following specification taken in connection with the accompanying drawing, in which Fig. 1 is a plan view of the shoe tree, with portions of the toe piece-broken away and in section to show the coaction of the thrust bar and the wedge; and 1 Fig. 2 is a side elevation of the tree with the parts positioned as they would be if it were within a shoe; indicated in dash lines.

The toe piece I0 is divided longitudinally in a vertical plane to provide two parts held loosely together by pins in the form of screws l2 and I4 which are threaded in'the left-hand section I6 and slidable in the right-hand section I8 in which recesses 20 are provided to receive the heads of the screws. nected to a flat heel piece 22 by means of a link 24 which cooperates with the heel piece to'form a toggle andalso acts as a thrust bar to push forward a flat plate-like spreader 26. This spreader, here shown in the form of a wedge, is received in grooves 28 in the inner faces of the toe part sections, as shown in Fig. 1, and it will be noted from Fig. 2 that these grooves are inclined downwardly and forwardly so that. any pressure against the back edge of the Wedge tends to push the toe piece 10 firmly against/the bottom of the inside of the shoe S, indicated in Fig. 2, and has no tendency to tip it up. The link or thrust bar 24 has a slot 30 near its forward end to surround the screw l4, thus giving a freedom of action which enables the rounded forward end 32 of this thrust bar to be brought against the back edge of the wedge regardless ofthe angular relation between the toe piece l0 and the heel piece 22. It will be understood that such differences of angular relation may be required by differences in heights of heel; and differences in the swing of the last. At the same time, the fact that the screw I4 is in the slot 30 insures the proper relationship between the forward end of the thrust bar 24 and the wedge 26. It will be noted that the inner faces of the toe piece sections arerecessed at 34 and 36 to permit the toe pieceto be completely collapsed without being held apart by the thickness of the thrust bar 24.

Although it will be understood that the forepart of my novel shoe tree may be combined with a variety of heel pieces, I have illustrated herein a simple and desirable form which may be cut from ordinary lumber with a minimum of skill and which is constructed to permit relative adjustinent between the thrust bar 24 and the heel piece 22 to accommodate different lengths of shoes. For this latter purpose, a series of holes 38 have been provided to receive a headed pin 40 passing through a single hole in the rear end of the thrust 'bar. The spacing of these holes is such that,

and mean for loosely connecting the thrust bar directly with the toe piece in position to bear against an adjacent end of the wedge.
