SPECIFICATION forming part of Letters Patent No. 621,238, dated March 14, 1899.
Application filed December 12,1898. Serial No. 699,029. (No model.)
To all whom it may concern.-
Be it known that I, SILAs A. FoRBUsH, a citizen of the United States, residing at Grafton, in the county of Worcester and State of Massachusetts;have invented certain new and useful Improvements in Insoles forShoes,
&c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in welt-shoes which have a cushion-sole on the inside of the leather insole; and it has for its objects to render such shoes easier of manufacture and cheaper and to produce a neat article provided with an improved comfortable cushion-sole.
111 the accompanying drawings, Figure 1 is a perspective View of the insole with a cushion-sole applied thereto. Fig. 2 is a crosssection of a shoe provided with my improved insole, taken at the broadest part of' the lat ter; and Fig. 3 is a similar cross-section taken a little in front of the middle of the shank of the shoe.
A is a leather insole which, in the usual manner, has its lower side undercut, as indicated at a, and which also has its under side skived off, as at b, forming a thin portion 0 at the edge.
G represents the cushion sole, which is formed of lambs wool or.a fine quality of corn-plaster felt or similar material, which has the soft-leather cover D, made of thin bleached calfskin or similar material, cut to the proper shape.
E is the upper. F is the lining of said upper, and G is the lip of the insole.
In manufacturing my-improved shoe I take the insole A after it has been cut and skived in the usual manner and cover the smooth top with a layer of cement of good quality. On top of this is placed a layer of lambs wool or other cushioning material, the cement causing it to adhere to the insole. Alayer of ce ment is then placed on top of the lambs wool, and on top of this is placed the bleached cover, which is held by the cement to the lambs wool or felt. This cover is of the exact size of the insole, except at the shank, where it is slightly wider and where it is bent down and cemented to the insole, as shown at 7c in Fig. 1.
It will be apparent that the edges of the cushioning material are exposed, the result being that it is more elastic, that it is less liable to become permanently flattened, and that it will act to absorb perspiration, mak= in g the shoe in which it is used more comfortable and healthful, especially in hot weather.
The advantages of this construction are that the cushion, being less confined,is more elastic than is usually the case with cushionsoles. It is cheaper and easier to manufacture and in actual use shows that it has no defects, the cover remaining under all ordinary conditions exactly in place.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is
A sole for a shoe, composed of an insole, a layer of cushioning material of the same size as the insole cemented thereto and a softleather cover cemented to said cushioning material, said cover being of the same shape and size as the layer of cushioning material, except at the shank, where it is slightly larger and is bent down over said material and ce mented to the insole, the edges of the cushioning material being exposed at all points except at the shank of the sole, substantially as described.
In testimony whereof I have aflixed my sig nature in presence of two Witnesses.
SILAS A. FORBUSII.
