JOSEPH S. OHARA, OF GRAND RAPIDS, MICHIGAN.

OVERSHOE.

SPECIFICATION forming part of Letters Patent No. 415,922, dated November 26, 1889.

Application filed July 3, 1889. Serial No. 316,396. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH S. OHARA, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Improvement in Overshoes, of which the following is afull, clear, and exact description.

My invention relates to an improvement in overshoes, and particularly to those manufactured from india-rubber and compounds of the same with other substances.

The objects of my invent-ion are to produce an elastic overshoe which will be neat in appearance, easy to manufacture by usual processes, and that from the peculiar conformation of the same will hold itself securely upon the leather shoe of a wearer without undue strain upon the front portion of the foot, so as to avoid improper pressure upon the toes and consequent pain in or numbness of these members.

With these objects in View my invention consists in certain features of construction, which will be hereinafter described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation in section of one form of the overshoe displaying myimprovement. Fig. 2 is a longitudinal section in elevation of a slightly-changed form of the overshoe. Figs. 3 and at are sectional side elevations of other modified forms of my improvement in overshoes. Figs. 5 and 6 are side elevations of the preferred form of construction, Fig. 5 being a sideelevation in section, while Fig. 6 represents the overshoe upon a wearers foot and in perspective. Fig. 7 is a perspective view of the bottom and side of an overshoe, which is similar in construction to that shown in Fig. 4:, and Fig. 8 is a plan view in section of the shoe shown in Fig. 2 taken on line 2 2 in said figure.

As before indicated, the preferred material used in the manufacture of this improved overshoe is the usual composition of vulcanized india rubber, which is strengthened by the proper combination therewith of woven cloth in alternating layers.

To effect the stated objects of my invention an essential feature consists of the integral formation of a swelling projection A, which produces a flattened rib vertically upon the rear wall of the shoe. There is also a corresponding thickening up of the front wall a of the recessed heel B. It will be noticed that the front wall just mentioned is varied in height in the several views shown, and that different degrees of inclination from a horizontal plane is given to this front wall, or it may be made vertical, as shown in Fig. 3. Upon the exterior surface of the shoe A an integral band or swell a (see Figs. 1, 2, 3, and 4) is produced, which extends from the front wall of the heel B, around the heel portion of the overshoe, intersecting the vertical rib A. As will be seen in the figures named, the band a is inclined upwardly as it extends rearwardly, so that a constricting cincture of denser material than the lower portion of the side wall of the heel is thus afforded, which will bind the recessed heel portion securely upon a proper -sized heel belonging to a leather shoe that is inserted therein, the line of constriction being indicated by the plane of inclination of the band a.

It is not material Whether the front wall of the heel recess or socket of the overshoe is vertical or somewhat inclined, as the conj unctive action therewith of the integral band CL will be equally as effective in retaining the overshoe in place upon an inserted leather shoe by constriction of the band upon the heel portion of the inserted shoe, without requiring a binding fit of the overshoe upon the front portion of the shoe.

In Figs. 5 and 6 there is shown a duplex band, the lower portion h of which encircles the heel portion B of the overshoe and grips the body of an inserted leather heel.

The upper band portion a extends from its point of junction 6 diagonally upward and rearward, so as to engage the rear wall of the overshoe at a point (1 above the natural rearward swell or protrusion of the heel, as shown.

The effect of the coacting construction produced by the diverging bands to h is to bind the heel portion of the overshoe firmly upon the wearers leather shoe and render unnecessary a compressing strain on the front portion of the foot, as is usual with ordinary gum overshoes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An elastic overshoe having an integral vertical flattened rib formed on the outer surface of the rear wall, and an inclined integral band formed on the outer surface of the shoe, which extends from the forward part of its heel around and upward, intersect ing the vertical flattened rib, substantially as set forth.

2. An elastic overshoe having a vertical flattened rib formed on the rear portion of its heel, a thickened front wall on the heel portion, and an upwardly and rearwardly extended encircling band integrally formed and joining the thickened front and rear portions of the heel, substantially as set forth.

3. An elastic overshoe having an integral duplex band formed upon its external rear portion, which band is adapted to bind the heel proper of an inserted shoe and also eX- ert an upwardly and rearwardly inclined constriction upon the rear portion of a wearers foot, substantially as set forth.

4. An elastic overshoe having a thickened wall formed integral with its recessed heel, and an external duplex integral band with a lower portion encircling the heel and an upper diagonally-inclined portion which exerts a constricting pressure on an inserted foot above the heel proper, substantially as set forth.
