CORK SHOE ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 1st, 1916.

Applicationfiled July 24, 1915, Serial No. 41,716. Renewed August 30, 1916. Serial No. 117,801.

To all whom it may concern:

Be it known that I, ADELBERT Loonwooo, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Cork Shoe Attachments, of which the following is a specification,

The object of this invention is to provide an attachment for shoes that is adapted to protect the feet of the wearer from the effects of heat, moisture or cold.

Another object is to provide a shoe attachment comprising independent sole and heel sections adapted to be secured to said shoe and to be yieldably connected so as not to interfere with the natural movement, of the feet of the wearer, when walking.

A further object is in an attachment for shoes comprising heel and sole sections adapted to be detachably secured to the shoes, and formed of a'composition cork like material which renders the device light of weight, and impervious to the action of heat, cold, or moisture, thereby adding considerably to the comfort of persons, whoare frequently exposed to the elements.

In the further disclosure of the invention, reference is to be had to the accompanying drawings constituting a part of this specification, in which similar characters of reference denote corresponding parts in all of the views, and in which Figure 1 is a. perspective view of the preferred embodiment of the invention. Fig. 2 is a vertical longitudinal sectional view therethrough. Fig. 3 is a transverse sec-. tion on the line 33 of Fig. 2: and Fig. 4: is a perspective view of .amodified form of device.

Referring more particularly to the views, the device comprises sole and heel sections 10 and 11, respectively, the same being preferably formed of ground cork, mixed with suitable adhesive, and pressed into a hard compact mass. the material is extremely light in weight, and possesses excellent qualities for resisting wear, and owing to its insulating properties prevents the passage of heat, cold or dampness, to the feet of the wearer, thereby protecting the health and comfort of persons subjected to exposed places.

The heel section 11 has secured thereto, as at 12, a heel casing 13, to which are fastened elastic band 17 It is well to mention that shoe straps 14, adapted to encircle the shoe of a wearer, and is provided with a buckle 15 so that the attachment can be readily and conveniently removed from the shoe.

Extending transversely across the front portion of the heel 11, and secured to the easing 13, is a rod 16, over which is trained an The latter extends to a rod 18, secured to the sole section 10 and is firmly fastened thereto as at 19. An adjustable clamp or buckle 20 is connected with the elastic band 17 and is adapted to lengthen or shorten said band so that the attachment may conform to various sized shoes. A clamp 22 is fixedly secured to the sole section 10 and is provided with a turned portion 23 which is adapted to grip the sole of a shoe to retain the sole section 10 upon said shoe.

In operation, the section 10 is slipped under the sole of a shoe until the clamp 22 firmly grips the same, then the heel section 11, is pulled rearwardly a slight distance, against the normal tendency of the elastic band 17, until the casing 13 encircles the rear portion of the shoe. The device may then be firmly secured in position by the tightening of the straps 13.

In the modified form illustrated in Fig. l, the device is shown to consist merely of a. sole section 30, a heel section being omitted, and preferably formed of cork like material. The attachment is secured to a shoe by means of a. clamp 31, which engages with the outer edge of the sole of a shoe; and an elastic clamp 32 which cooperates with the instepof a shoe to rigidly retain the attachment in place.

From the foregoing it is obvious that the device embodies a very practical construction of light weight, considerable strength, of few parts, capable of being manufactured at a very low cost, and will conform with the demands of persons subjected to exposed or unprotected weather conditions.

With the above description the advantages of construction and method of operation, of the present invention, will be readily apparent, and, while having described the principle of operation of the mechanism comprising the preferred embodiment of the invention, it is to be understood that the construction shown is merely illustrative so that such changes may bemade when desired as fall within the scope of the claims.

I claim:- I r 1. An article of manufacture comprising cork sole and heel sections, a casing connected to the heel section, a rod passing through said casing, a second rod passing through said sole section, yieldable means trained over both of said rods for connecting said sections, means connected With said yieldable means for regulating the combined length of said sections, and fastening means carried by the sole section for attaching purposes.

2. An article of manufacture comprising cork sole and heel sections, a casing connected to the heel section, a rod passing through said casing, a second rod passing through said sole section, yieldable means trained over both of said rods for connecting said sections, means connected with said yieldable means for regulating the combined length of said sections, and fastening means carried by the rod passing through the sole section for attaching purposes.

3. An article of manufacture comprising cork sole and heel sections, a casing con nected to the heel section, a rod passing through said casing, a second rod passing through said sole section and disposed in parallelism With the first mentioned rod, yieldable means trained over both of said rods and connecting said sections, and means connected With said yieldable means at a point beneath the same for regulating the combined length of said sections, and fastening means carried by said sections for attaching purposes.

In testimony whereof I aflix my signature.

ADELBERT LOCKWOOD.
