BOOT TREE AND STRETCHER Patented March 26, 1907.

Application filed November 8, 1306. Serial No. 342,516.

Toall; whom it may concern: p Be it known that i, FnANo s A. MACKEN- zIE, a citizen of the United Statearesiding at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Boot Trees and Stretchers, of which the following is a specification.

j This'invention relates to boot trees and stretchers, and aims to provide in a manner hereinafter set forth an ad'ustable combined boot tree and stretcher a apted for use for various shapes and sizes of boots or shoes.

The inventionfurther aims to provide a boot tree or stretcher with means hereinafter set forth which will enable the stretching of a boot'or shoe at any part of the vamp thereof, both as to length and width.

The invention further aims to provide in a manner hereinafter referred to an adjustable boot "tree and stretcher adapted to fit the boot or shoe like the ori inal last and, further, when stretching to gradually aplply the pressure, so as to prevent straining t 1e stitches or leather ofthe boot or shoe.

The invention further aims to provide in a manner hereinafter set forth an adjustable boottree and stretcher which by its use will enable any undue pressure of the shoe upon the wearer bein removed, so that the shoe willfi-t in a satisfactory manner. I

The invention further aims to provide a boot tree and stretcher which shall be simple in itsconstruction, strong, durable, efficient in its use, and comparatively inexpensive to manufacture and having great capacity of adjustment. I

'With' the foregoing and other objects in view the invention consists of the novel combination' and arrangement of parts hereinafter described, and illustrated in the accompanying drawings, wherein is shown the reerr'ed embodiment of the invention; butit is I to be understood that changes, variations, and modifications can be resorted to which come fully within the scope of the claims hereunto a pended.

In descrfiaing the invention in detail reference ishad to the aocom anying drawings, wherein like characters 0' referencs'degnote co rriespo'nding plarts throughout the several "views,and in w h Figure 1 is aplan viewj Fig. 2,, a longitudi nal horizontal section a1 view showing one adjustment of the parts; Fig. 3, a similar view 5 through the bee section.

Preliminarily to amore detailed description it may be stated that in the embodiment of my improvements herein shown I construct the combined treefand stretcher of two hinged sections, one of which is formed of two laterally-adjustable members, each of. the said sections adapted to the other for the purpose of insertion within a boot or shoe,

and connecting the said sections are'adjust mg devices of special construction and organ- 7o ization, whereby the foreart section formed of two members can be a justed to the width of the boot or shoe, so as to fit the same like the original last or be adjusted to greater width to stretch the vamp at any oint desired or to fit shoes of different widt and so that one section can be adjusted or extended relatively to the other to enable the combined tree and stretcher to be used for boots or shoes of various lengths. The said adjustin devices are so constructed and arrange as to permit of the members of one of the foreart sections whenadjuste d to be firmly he (1 in any position of adjustment. The said construction also comprises effective means whereby the combined tree and stretcher may be withdrawn in its entirety from the boot or shoe whenever desired after performing its function'as a tree or as a I stretcher.

Referring to the drawings by reference characters, 1 denotes the forward section, and 2 the rear section. The former is constructed of two movable members 3 4, which when in normal position are adaptedto abut 5 against each other, so as to constitute what may be termed a -form or last. Each ofthe movable members has the inner face substantially centrally thereof provided with a longitudinally-extending groove 5,whic l} 1"oo extends from the rear end of and terminates at a point removed from the forward end of the member. The groove 5 near the forward end is formed with an offset 6, forming there by a pair of shoulders 7 and 8,the'- latter being inwardly beveled. Forwardly of the shou der 8 the inner wall of the groove 5 is beveled, as at 9. Thewall of the groove 5 of;

' devices 20.

one of the members opposes the wall of the groove 5 of the other member, and seated in the grooves is loiigitudinally-shiftalilc arm 10, the function of which is to spread the members 3 4 to stretch the boot or shoe when used asa stretcher or so that the section '1 may fit shoes of greater width. lhe arm .10 has its forward end in the form of a spear or arrow head, as at 11, and the said end ll is connected by an intermediate cylindrical shank 12 to an enlarged rear portion 13, the latter being bifurcated, as at 14, and bevsled, as at 15.

The forward end of the members 3 4 are connected through the medium of a stopscrew 16, the latter being fixed at one end to the member 3 and loosely engaging in the member 4. The screw 16 is of less length than the combined width of the members 3 4, so that the forward. end of the members can be spread when the arm 10 is shifted forwardly, and the head or the screw 10 limits the spreading movement of the members. A shoulder 17 is provided in the wall of the opening 18, in which a portion of the screw 16 plays. The shoulder acts as an abutment for the head of the screw 16 when the members are spread. The rear ends of the memhere 3 4 are connected together by a s ringplate 19, retained in position by the ho dfast the plate 19 to allow of the spreading of the members at an angle with respect to each other when the arm 10 is shifted forwardly. The rear or what may be termed the heelsection 2 is cut away to form achamberll, divided by a bridgc-piece 21 into a forward and rear section. Vv'ithin the chamber 21 is positioned a slidable actuating-bar 22, which is slotted, as at 23, and has a toothed biurcated rear end :24. The bar 22 is provided with graduations 25, so that the movement thereof can be regulated, and the said bar 22 is retained upon the bottom of the chamber There is suflicient resiliency in l l l l 21 by the bridge-piece 21 and further by a l headed holdfast device 26, which also acts as a stop for limiting the increment of the bar 22 in either direction, as the holdl'ast device 26 extends through the slot 2?), the end walls of the latter forming abutmcnts for the holdfast device. The bar 22 is shifted in either direction through the medium of a pinion 27 engaging the toothed bifurcated end 24 of said bar 22. The pinion 27 extends through the rear end of the bar 22 and is preferably formed by toothing cylindrical member 28, carried on the lower end of an operating-handle 29. The cylindrical member 28 is positioned in the rear section. of the chamber 21,

and the portion 30 thcreol,which is of greater diameter than the pinion 27, is held against the lower face of the bifurcated end 24- of the bar 22 by a compression-spring 31, seated in a recess 32, which is formed in the bottom oi the chamber 2]. From the foregoing construction it is evident that when the handle 29 is rotated in one direction it will cause the shifting of the bar 22 and the forwardsection 1, pivoted thereto, forwardly, and when rotated .in the opposite direction the bar 22 and forward section 1 will be returned to their normal position.

The rear section is hinged to the forward section 1 by means of pivotally connecting the forward end of the bar 22 to the bifurcated end 14 of the arm 10, as at 33. To permit of the swinging of the rear section. with respect to the forward section, the latter is cut away, as at 34, and by such an arrangement it will be evident that either of the sec tions can be swung upon the pivot 33 upwardly, but that the downward movement of either oi the sections will be limited, as the forward section will act as an abutment for the rod 22 or arm 10. The slidable actuating-bar 22 and pinion 27 not only provide means for adjusting the forward section 1 with respect to the section 2 for varying sizes oishocs or boots, but also provide means for shifting the arm 10 and cause the spreader or arrowhead 11 thereof to stretch the boot or shoe to cause the forward section 1 to fit boots or shoes of various widths.

It is thought that the operation of the combined boot tree and stretcher can be fully understood from the foregoing description, taken in connection with the accompanying drawing; but it will be stated that after the sections have been adjusted to the length desired and inserted in the boot or shoe if it he desired to stretch the latter or if it he desired to increase the width of the forward section to fit the handle is rotated,

so as to cause the bar 22 to move forwardly, which in turn will shift the arm 10 in the same direction, the beveled side portions 15 will ride against the walls of the grooves, and the spcar-shaped end 11 of the arm 10 igainst the bevels 9 and cause the members 3 4- to spread,thereby increasing the width of ih'e forward section and stretching or fitting the lmot or shoe, as the case may be. The members 3 4 will remain in their adjusted position until the handle is rotated in the opposite direction, which will withdraw the bar 22, the latter carrying the arm 10 here- 3 forward section comprising a pair of mov- 1 able members connected together, each of said members havinp its inner face provided with a l'ongitudmany-extending groove havinc a beveled portion and a shoulder, a longitudinally-shiftable spreader-emu seated in said grooves, and adapted to engage the beveled portions and shoulders, a longitudinally- ICO shiftable actuating-bar seated in said rear section, means for hinging the bar and arm together, and means engaging the bar for shifting it.
