8 Claims.

This invention relates to rubber overshoes. It is particularly directed to men's overshoes made of elastic rubber without cloth lining.

' Heretofore, it has been found necessary to manufacture rubber overshoes in a large number i of sizes in various shapes in order to insure a good flt on a corresponding large number of sizes and shapes of shoes. It has been found, furthermore, that rubber overshoes as madeheretofore press the front or vamp portions of the shoes where the leather is soft and consequently, pressure is transmitted to the foot causing sweat and undesirable fatigue. It is therefore an object of the invention to provide a rubber overshoe which will fit various sizes and shapes of shoes, and which will not press unduly hard on the vamp portion of the shoe, whereby said overshoes will be comfortable to wear. a

It has been found, furthermore, that the rear portion of similar rubber overshoes as heretofore made overlap the upper edge of the shoe and unnecessarily extend into the trousers thereby soiling the socks and unduly pressing upon the sensitive tendons of the feet. It is therefore a further object of this invention to provide a rubber overshoe in which the rear curved part of the counter terminates below the soft leather zone at the upper edge of the counter of the shoe on which the overshoe is worn, whereby the pressure is confined to the hard capped portion of the shoe counter. To this end, the upper edge of the overshoe forming the entrance for the shoe, is in an inclined plane slanting downward toward the rear, instead of upwardly toward the rear, as in such type of overshoes now in use.

A further object of this invention is to provide an overshoe in which the counter is undersized relative to the vamp portion of the overshoe, being narrower than the counter portion of the ordinary overshoe, so as to firmly though elastically grip the counter of shoes for which the overshoe is intended, thereby relieving'the pressure from the vamp portion of the shoe.

Still another object of this invention is to provide an overshoe having walls extending upwardly from the bottom of the overshoe and inclined inwardly and upwardly all around, whereby, when the overshoe is worn the heel of the shoe and the edges of the sole of the shoe will press outwardly, to extend said inclined portion of the overshoe, straightening the same, whereby more than one size and shape of shoe may be worn with the overshoe, said inclined portions of the overshoe in the bottom of the overshoe being thicker than the vamp and counter portions of the overshoe in order to ensure sufliciently firm though elastic resistance against spreading.

Yet another object of this invention is to provide an overshoe of the character described, having a substantially triangular shaped opening at the top with linearly straight edges forming a constricted entrance for the shoe, adapted to have its edges stretched upon the leather of the shoe, said triangular opening perferably having its apex forwardly and the base at'the rear.

Yet another object of this invention is to provide an overshoe of the character described, having portions adjacent the opening of the overshoe, and on either side thereof, inclined upwardly and inwardly and increasing in width toward the front, said portion being adapted to open out againstthe leather upon being forced out by the greater bulk of the shoe upon which the overshoe is worn.

Still another object of this invention is to provide a light, strong and durable overshoe of the character described, which shall be relatively easy to don and doll, and which shall be relatfvely inexpensive to manufacture, attractive in appearance, and efiicient and practical to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is a top plan view of an overshoe embodying the invention;

Fig. 2 is a side view thereof;

Fig. 3 is a side elevational view of the imwill assume its original shape as soon as it is removed from the shoe, without deformation.

The overshoe I comprises a .sole portion or bottom wall I I, extending along the whole length of the overshoe from front to rear. Extending upwardly from the wall H in integral relation therewith is an upwardly and inwardly inclined lower side wall l2, adapted to be contacted by the sides of the heel and edges of the sole of the shoe. The wall I! inclines inwardly all around the shoe, so that when the shoe is worn the heel and sole of the shoe will press outwardly on the inclined wall 12 to expand and contract the same, as shown in Figures 4 and of the drawing. The walls II and I! are preferably relatively thick as shown in the drawing.

Extending upwardly from the wall I! in integral relation therewith is a front vamp portion It and a rear counter portion IS. The vamp and counter portions I 4 and I5 are thinner than the walls II and I2, and extend upwardly from the inner edge of the wall I2 leaving an outer ledge 16, at the upper edge of the wall I2, and

forming thus an angular waist along the ledge l6. It will be observed by reference to Fig. 4 that the inner surface of the counter portion l5 of the upper forms an obtuse angle with the adjacent part of side wall I2.

The overshoe is formed with an opening It at the top, of substantially triangular shape and having a curved portion l9 at the rear, and forwardly converging portions 20 extending from the rear curved edge, towards the sharply inclined edge portions 2|, at the forward ends of the edges 20.

It will be noted that the opening I8 is generally of triangular shape with the base at the rear and the apex at the front.

At each side of the edge portions 20 of the opening !8, are triangular wall portions 25, inclined upwardly and inwardly. The edge at the opening I8 is in an inclined plane slanting downwardly towards the rear, for the purpose hereinafter appearing, so that the rear curved edge portion 19 is lower than the front apex portion of the opening. The board part of the entrance opening l8 at the rear makes it easier for the overshoe to be put on or taken off the shoe.

When the overshoe is in position on the shoe, as shown in Figure 3 of the drawing, the triangular opening I8 is considerably stretched, with the result that its edges are tightly forced against the leather of the shoe to make a watertight closure. Furthermore, the triangular portions 25 being forced to open out by the bulk of the shoe, the lateral stretch thereby created, further contributes toward making the closure adjacent the edges of the opening more Water-tight.

It will be noted that the edges of the opening [8 lie in a plane inclined downwardly toward the rear, the rear curved portion [9 corresponding to a point lying below the highest point of the counter stiffener 3| of the ordinary shoe. With this construction the soft leather zone 30 at the upper edge of the counter of the shoe which covers the sensitive tendons of the foot is not touched by the rubber overshoe, the pressure of the overshoe being confined to the hard and rigidly capped portion of the shoe counter. The pressure of the overshoe will thus not be transmitted to the rear of the foot, adjacent the upper edge of the shoe.

The overshoe I 0 may be worn with various shapes and sizes of shoes equally well.

It will be noted that the angular portion of the overshoe in the region of the ledge I8 is constricted and is adapted to expand and contract to accommodate itself to shoes of larger or smaller bulk, adjacent the bottoms of the shoes between limits. With this construction, one overshoe can be properly fitted to shoes of different shapes and sizes, fitting them all equally well.

The inwardly inclined wall I2 is relatively thick all around, so as to offer greater resistance to spreading when a shoe is inserted into the overshoe in order to obtain exact accommodation to the size of the shoe at that zone.

The width of the counter portion ii of the overshoe is underdimensioned relative to the forward vamp portion ll, being proportionately narrower in relation to the vamp than the counter of the ordinary rubber overshoe. Thus the counter l5 of this overshoe is smaller relative to the vamp I4 thereof, than is the counter of the ordinary shoe to the vamp thereof, so that when the overshoe is worn, the counter I5 of the overshoe will more firmly grip the counter of the shoe than will its vamp ll grip the vamp of the shoe. With this construction, the injuring pressure on the vamp of the shoe is relieved and furthermore, the possibility of the overshoe being pulled off the shoe by sticky mud or snow or slush is entirely obviated. Furthermore, since the counter portion of the shoe is stiffer than the vamp portion of the shoe, it is the proper place for the overshoe to grip the shoe.

Inasmuch as the counter portion i5 and the vamp portion H, and also the top portion of the overshoe are made of substantially thin rubber, and since the rubber is highly elastic, and inasmuch as the pressure that the overshoe exerts is opposed by the hard or stiff portion of the shoe counter and by the hard edge of the shoe sole and heel, substantially inappreciable pressure is transmitted to the foot itself, so that the overshoes are extremely comfortable to wear.

It will thus be seen that there is provided a device ln which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
