COMBINED SHOE TREE AND DRIER.

Application filed June 26, 1922. Serial No. 571,006.

To all whom it may concern:

Be it known that I, ANN G. DOYLE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Combined Shoe Trees 'and Driers.

The invention relates to shoe trees having means within the tree for producing heat to expedite the drying of a shoe placed upon the tree.

The primary object of the invention is to provide a shoe tree having heating means tperewithin to expedite the drying of a s me.

A further object of the invention is to provide a device of the character stated that will be light, eflicient and durable and one that will be economical of manufacture.

Other objects of the invention will appear from the following description which is directed to the preferred embodiment thereof, reference being had to the accompany.- ing drawing which forms a part of the specification, the features of novelty being pointed out more particularly in the appended claims.

In the accompanying drawings the invention is illustrated as applied to a combined drier form and shoe tree.

Fig. 1 is a top plan view partly in section of a shoe tree with the invention applied thereto.

Fig. 2 is a top plan vie-w of a shoe tree with the top section removed to more clearly show the invention as applied thereto.

Fig. 3 is a longitudinal vertical section taken on line 33 of Fig. 1 with a portion thereof broken away and showing the device in flexed position in dotted lines.

Fig. 4 is a vertical section of the upper part of the ankle portion of the shoe tree with the lower portion thereof broken away showing the connecting cable introduced into the device through the handle thereof.

Like reference characters indicate like parts throughout the several views of the drawings.

In the construction of the improved drier form comprisinga shoe tree the body portion thereof is made of two pivotall related hollow sections indicated generally by the reference characters A and B. The sections A and B are preferably made of comparatively thin aluminum, although any other suitable material may be employed and the device may be either molded or stampedfrom thin sheets of the metal of which it is made.

Reference character 10 indicates a plate made of asbestos, mica or any other suitable insulating material and which is secured to the bottom wall 11 of the section B by bolts 12 which are screw threaded adjacent their lower ends adapting them to have screw threaded engagement with the bottom wall 11 of section B. Hollow spacing and insulating members 13, 1 1 and 15 through which bolts 12 pass are provided for spacing and insulating resistance wire 16 from the bottom wall 11 of section B. Insulating plate 10 extends from insulating member 13 to insulating member 15 and has wound V therearound a resistance wire 16. Insulating plate 17 which like insulating plate 10, may be of asbestos, mica or any suitable insulating material, is secured to the bottom wall 18 of section A by bolts 19 which are screw threaded adjacent their lower ends for screw threaded engagement with the bottom wall 18 of section A. Hollow spacing members 20, 21 made of any suitable insulating material are provided for spacing and insulating resistance Wire 22 from the bottom plate 18 of section A and through which members bolts 19 pass. Insulating plate 17 extends from insulating member 20 to insulating member 21. The respectiveends of resistance wire 16 in section B are connected with the respective ends of resistance wire 22 in section A of the shoe treeby yielding current conducting members 23 and 24 which are made in the form of helical springs of any suitable electric current conducting material, the connections being indicated by reference characters 25, 26, 27 and 28. Section B is bifurcated at its inner end to co-operatively receive the reduced inner end portion 29 of section A between ears 30 and 31 of section B. Ears 30, 31 have apertures 32, 33 therethrough which are adapted to register with apertures 35, 36 through the walls of the reduced portion 29 of section A and receive pivotal pin 37 therethrough which pin in the drawings is shown as a cotter pin although any other suitable form of pivotal member may be employed. Ear 30 is recessed as at 38 for the reception therein of the head of cotter pin 37 in order that the head of the cotter pin may lie flush with the outer face of the wall of the ear, while ear 31 has a substantially V-shaped recess 39 to provide for the spreading of the ends of the cotter pin at a point inside of the face of the ear. By this arrangement the opened ends of the hollow sections are positioned adjacent each other so that the sections are in communication with each other thereby heating the entire shoe tree evenly throughout. Gonductor rods a0, 41 pass downwardly through section A forming. the ankle portion of the shoe tree and are connected to resistance wire 22 as at a2. The upper ends of the conductor rods an, 11 are connected to the service wires of cable a3 in the usual manner. Connector rods 40, ll pass clownwardly through and are spaced from the rear wall of the shoe tree by insulating blocks ea secured to the rear wall or" the ankle portion of the shoe tree by screws 45. Section A may be made in two pieces comprising an ankle portion C and a heel portion D, the heel portion D having internally screw threaded thickened portions 46 ad j acent the upper end of the wall thereof for screw threaded engagement of screws l? which pass downwardly through the bottoms of recesses 48 formed adjacent the lower edge of the wall of section C for securing the ankle portion t) and the heel portion D together. A handle 51, through which the service wires of cable 43 pass and are connected to conductor rods a0, 41, is provided for grasping with the hand to insert or re move the tree from a shoe.

ln the employment of my invention the tree is flexed or the rear or heel portion turned forwardly on the pivotal member 3? as shown in dotted lines in Fig. 3 and the section B of the shoe tree inserted downwardly through the top and into the toe of the shoe when the heel portion D is moved downwardly on the pivotal member 37 contacting with the inner face of the counter in the heel of the shoe causing a wedging action bysect-ion A against section B, forcing section B forwardly in the toe of the shoe, thereby causing the toe of the shoe to assume its proper and normal shape and maintain ing the toe of the shoe in suh proper and normal shape during the process of drying. When the heel portion of the tree is moved forwardly as indicated in Fig. 3 the distance between the respective ends of the resistance wires 16 and 22 will he increasedowing to the difierence in position of section A with relation to section B. This increase in the distance between the resistance wires 16 and 22 when the tree is flexed, as shown in Fig.

3, is provided for by the employment of helical spring members 23 and 24: for connecting the ends of the respective resistance wires.

While the device as described in the specification and illustrated in the accompanying drawings may be made of any suitable ma terial, in the interest of lightness in weight, it is preferably made of aluminum.

it will be obvious that the shoe tree may be introduced into a shoe such as a white shoe, for example, and a liquid cleaning material used for cleaning the shoe and the heating element within the shoe tree operated and the shoe quickly dried.

In order that the invention mightbe understood, I have shown the details of the preferred embodiments of my invention, but it is not desired to be limited to the mere details of construction, for it will be apparent that persons skilled in the art may resort to various modifications without, departing from the purpose and spirit of the invention.

I claim:

1. A hollow shoe tree comprising two pivotally connected hollow sections, an electric heating element in each of the sections. electric conducting members in the form of helical springs connecting the heating elements. and each of said hollow sect-ions arranged in communication with each other whereby the heat is evenly distributed throughout the entire shoe tree.

2. A hollow shoe tree comprising two pivotally connected hollow sections having commu nicating opened ends, an electric heating element in each of the sections, electric conducting members in the form of helical springs extending through the opened ends in said sections for connecting the heating elements, whereby the entire shoe tree wlll be evenly heated throughout.

3. A hollow shoe tree comprising two pivotally related sections formed in a manner to occupy substantially the entire shoe to be dried, each of said sections having opened ends adjacent their pivotal connections whereby said sections are in communication with each other and an electric heating element in each section and connected with each other through the opened ends in said section.

In testimony whereof I have signed my name to this specification, on this 21st day of June, A. D. 1922.

ANN G. DOYLE.
