UNITED STATES GEORGE P. OLAR KE, OF BROOKLYN, NEW YORK.

PATENT OFFICE.

IMPROVEMENT IN BOOTS'AND SHOES.

Specification forming part of Letters Patent N o. 47.521, dated May 2, 1865.

.To all whom it may concern.-

. Be it known that I, GEORGE P. CLARKE,

of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Boots and Shoes; and I do hereby declare that the following is a full,

clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being bad to the accompanying drawings, forming part of this specification.

The present invention consists in inserting Within the sole or ordinary treading-surface ot' "a boot or shoe, and securely fastening the same therein by any proper means, a series of studs, of any desired number and size, and

made of any suitable elastic and flexible materialsuch as india-rubber-or gutta-percha, or their compounds-said studs projectin goutward from said sole, and forming the treadothers which it is not necessary to mention,

as they are plainlyapp'arent to all.

In the accompanying drawings my improvements are represented, Figure 1 being a view of the under side of the sole of a boot Fig. 2, a central longitudinal vertical section through plane of line as as, Fig. 1.

a a in the drawings represent the sole of a boot or shoe made in the ordinary form and attached to the upper-leather in any proper manner. In sole a a, and extending entirely through the same, are inserted in propershaped openings, 11b, &c., therefor, and firmly held by means of cement or other proper mode, a series of elastic studs, 0 a, made either of india-rubber or gutta-percha, or of both together, or of either of their respective compounds, or of any other elastic and flexible material, and of any desired shape and size. These studs 0 a project a short distance from v the exterior surface of the sole-piece a a, formn be deemed best.

From the above description it is'evident ing the treading-surface for the boot or shoe. In heel d d of the boot or shoe similar elastic studs, f f, 850., and of any number, may be inserted, if desired, or the studs may be only I inserted within the sole, according as it may that by inserting elastic studs within and projecting from the soles of boots and shoes, asabove described, or in other proper manner,

an-elastic, easy, and light-treading sole is secured, andalso its durability is much increased. These studs also will prevent slipping when walking upon slippery walks, and in ordinary moist weather will prevent moisture from penetrating the sole, and thereby keep the feet dry.

There are,- of course, many sizes, shapes,

and modes in and'by which the elastic studs herein described can be formed and fastened to and in the soles of boots. or shoes, and also va rious ways in which they can be arranged therein, either inparallehstraight, or curve lines; and therefore 1 do not intend .to limit myself to any particular form, sizejor mode of insertion for the studs, or to the form and mode herein described. These elastic studs may with great advantage be applied either to the inner surface of a machine belt or band or to the peripheryof its pulleys,as' they'pre.

, vent thereby the slipping of thebelts 0n the pulleys, for which I intend hereafter to make application for separate Letters Patent of the United States.

" -'I: clai1n as new and desire to secure by Letters Patent- Inserting within or attaching to the sole and heel of a boot'or shoe,.orin and to any desired portion of the same, "a series" Qf elastic studs or projections, made off-any suitable flexible and elastic material, an'dof any desired'numher, size, and shape, substantially as described, and for the purposes specified.

GEORGE P. CLARKE.
