JAMES DE SELDING BROWN, OF NEW YORK, N. Y. HEEL FOR BOOTS AND SHOES.

Application filed- July 28,

To all whom it may concern.

Be it known that I, JAMES DE SELDING BROWN, a citizen of the United States, residing in the city of New York, borough of Manhattan, in the county and State of New York, have invented a certain new and useful Improvement in Heels for Boots and Shoes, of which the following is a specification.

The invention relates to heels of the composition or wood type, and the object of the mvention is to provide an economically manufactured heel which shall be light, strong and tough and impervious to water, and which, with a top-lift therefor, is adapted to receive and hold a surface coating which shall be hard and wear-resisting and impart the desired color and finish.

The invention consists in certain novel features of construction and treatment by which the above objects are attained, tobe hereinafter described and claimed.

The accompanying drawings form a part of this specification and show a heel constructed in accordance with the invention.

Figure 1 is a side elevation of the improved heel, and Figure 2 is a vertical longitudinal section, taken on the centreline of such heel.

The preferred heel block is formed by mixing hardwood sawdust with glue size or like pasty cement or sufficient tenacity to permit the plastiomass to be shaped in a suitable mold under pressure and to maintain its shape without checks or pits when removed therefrom. Fibre which may be leather, cotton, linen, shoddy or the like may be added to the mass to strengthen such thin overhanging parts as the shank breast 5 and seat-edges 6 of the heel.

When the block thus formed is dry it is soaked in nitrocellulose in solution which penetrates the pores and interstices and when the solvent of the nitrocellulose has evaporated the block is found to be strong and tough, well adapted to receive and hold e nails of the heel-seat, and practically homogeneous throughout and waterproof.

Any slight surface roughnesses may be smoothed y sandpapering and the block is then ready to reoeive'its coatin plied by dipping in nitrocelluI mg. no such coat will suflice but it is preferable to give the block two or more dipinsure a smooth exterior surface, one of which may be the color coat.

ose and drywhich is ap- 1922. Serial No. 578,102.

The desired coloris made by adding. stains or pigments to the nitrocellulose bath. As the addition of coloring matter to the nitrocellulose-solution tends to lessen the hard ness and lustre of the finishedsurface, it is preferable after applying the color coat to dip again in the first or another uncolored or transparent nitrocellulose bath to insure the desired glassy highly lustrous surface having the desired hardness, and capable of withstanding the friction and scratches of ordinary wear without affecting the polish.

The top-lift 7 is preferably of felt, or analogous matted fibre, of about three sixteenths of an inch in thickness, saturated with nitrocellulose in which it may be clipped in sheets and dried, and which may be of leather color, subsequently cut by dies to the shapes and sizes required. The lift may be nailed to the block before the latter receives its color coat and the protective and finish coat, or may be applied later and trimmed, colored and burnished in place.

Instead of the top-lift of felt, treated as above set forth, a top-lift of leather, trimmed, colored and burnished in the usual manner may be employed, but the heel produced as first described is preferred because of its lightness, strength and toughness, the wearing qualities of its hard surface, and its attractive appearance.

In th blocks may be treated simultaneouslythus reducing the labor cost and permitting the heels to be manufactured at a minimum expense.

I claim 1 1. As an improved article of manufacture, a heel comprising a molded block composed of sawdust and a soluble binder, and sat urated with nitrocellulose.

2. As an improved article of manufacture, a heel comprising a molded block composed of sawdust and a soluble binder, and saturated with nitrocellulose, and a finishing coating thereon.

3. As an improved article of manufacture, a molded heel formed of sawdust and a soluble binder, and an impregnating hardening and solidifying agent.

In testimony that I claim the invention above set forth I aflix my signature.
