Application filed April 20,1905. Serial No. 256,563.
To all whom, it may concern:
Be it known that I, IVILLIAM D. WILDER, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Shoe- Trees; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention is an improved shoe-tree and it consists in the construction, combination, and arrangement of devices hereinafter described and claimed.
The object of my invention is to effect improvements in the construction of a shoetree whereby the heel portion is pivotally connected to the front portion for angular movement to facilitate the placing of the tree into a shoe and the removal of the tree therefrom and whereby the heel portion is rendered longitudinally adjustable with respect to the front portion of the tree, and the latter is vertically adjustable, so that the tree may be used in shoes of varying sizes.
In the accompanying drawings, Figure 1 is a side elevation of a shoe-tree embodying my improvements, showing the same in one position in full lines and in dotted lines with the heel portion raised and extended longitudinally from the front portion and also showing the instep portion of the shoe adjusted to a raised position in dotted lines. Fig. 2 is a longitudinal central sectional view of the same. Fig. 3 is a vertical transverse sectional view through the heel portion, taken on a plane coincident with the clampingscrew. Fig. 4 is a transverse sectional view through the front portion of the tree, taken on a plane coincident with the adjustingscrew; and Fig. 5 is partly a side elevation and partly a sectional view showing a modified construction of my improved tree.
The front portion 1 and the heel portion 2 of my improved tree, which are appropriately shaped and are of any suitable size, are connected together by a link 3, the front portion of which lies in a recess 4 at the rear end of the front portion 1 of the tree and is pivotally connected to the front portion 1 of the tree by means of aremovable pin 5, which may be inserted in coincident openings in the front portion 1 and link 3. The rear portion of the link 3 operates in and extends through a longitudinal slot 6, with which,the heel portion 2 of the tree is provided. The under side of the link 3 is serrated to provide a plurality of adjusting-notches 7. A clampingscrew 8 has its stem fitted in an opening 9 in the heel portion 2, which opening 9 extends across and communicates with the slot 6. The said stem of the adjusting-screw is rabbeted in one side, as at 10, for the reception of the link 3 and is provided near its lower end with a tooth 11, adapted to engage any of the notches 7 of the link. The nut 12 of the clamping-screw is cylindrical in form, 0 erates in a socket 13 in the upper side of tl fe heel portion, and is formed or rovided with a handle 14. By this means t 1e nut may be turned to engage the tooth 11 with one of the notches of the link or to disengage the same therefrom.
It will be understood that when the clamping-screw is disengaged from the link the heel portion may be adjusted longitudinally toward or from the front portion 1 of the tree to vary the length of the tree asmay be required, and it will also be understood that when the clamping-screw is engaged with the link the heel portion is fixed at any desired longitudinal adjustment with respect to the front portion 1 of the tree and is adapted to be turned angularly with respect to the front portion, as shown in dotted lines in Fig. 1, to facilitate the placing of a tree in a shoe or its removal therefrom.
The front portion 1 of the tree is provided with a horizontal longitudinal kerf, which extends from a point at'or near its rear end to Within a suitable distance of the toe and which kerf enables the tree to be expanded vertically, so that the tree may be caused to fit in shoes of varying sizes. Within the scope of my invention any suitable means may be employed for thus expanding the tree. In Figs. 1, 2, and 4 I show an adj usting-screw 17 for this purpose, which screw has a threaded portion engaging the threaded opening in the instep portion and has its stem swiveled to the lower portion of the part 1 by a plate 18 and provided with a winged head 19 whereby the screw may be readily turned,the said winged head being disposed in a recess 20, with which the part 1 is provided.
In the modified construction of my invention shown in Fig. 5 I employ an eccentric cam 21 for the purpose of adjusting or vertically expanding the tree, the said eccentric cam being shown as mounted in the instep portion of the tree and as engaging the lower portion thereof.
From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily undersood without requiring a more extended explanation.
Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
Having thus described my invention, what the tree and extending into said longitudinal slot of the heel portion, said link having notches in its lower side, a screw-stem in the vertical opening of the heel portion, recessed on one side to receive the link and having a tooth to engage any of the notches of the link, and a handle, bearing on the heel portion of the tree, having screw-threaded engagement with the screvwstern and forming a nut to move the screw-stem endwise to engage or disengage the link to permit longitudinal ad iuslgment of'the heel portion of the tree on the In testimony whereof I have hereunto set my hand inpresence of two subscribing wit- IlGSSGS.
