To all whom it may concern:

Be it known that I, ALBERT E. ROBERTS, a citizen of the United States, residing at Norwalk, in the count-y of Huron and State of Ohio, have invented a certain new and useful Improvement in Rubber Overshoes, of which the following is a full, clear, and exact description. V q

The prior Patent No. 736,156, granted to sandal overshoe or rubber, of whichthe front part of the upper is provided with an :internal bead, wherein a cord is embedded.

This cord, embedded in this internal bead, extends around the toe and along the .sides of the upper near the top edge thereof to a point near the heel; and it goes around the [heel embedded in an external bead. The purpose of the internal bead'in the front part of the upper is to go into the crease between the upper and sole of the shoe on which the rubber is used, so that fit overthe rubber is made diificult. Therubber which forms the subject matter of said patent is being manufactured and sold under the name of Eversticl Whensuch a rubber is nicely fitted to the shoe upon which itis worn, it is entirely "satisfactory. If,

however, an Everstick rubber is put onto a shoe having a sole muchthicker than that of the shoe for which therubberwas-constructed, the said bead cannotoverhang the shoe sole, and therefore the rubber is not held on the shoe. If, on the other hand, such a rubber is put ontoa shoe havinga sole much thinner than that for which the rubber was intended the said internal bead will not enter the crease of the shoe and will not engage with the sole thereof. It will, on the contrary, engage with the upper some distance above the crease, andthe result will be that the rubber will not fit the shoe properly andwill have more or less play thereon. It is therefore likely to come off easily; but the chief objection is that as the rubber moves onthe shoe this bead. will chafe the leather of the shoe upper. This sometimes does no greater damage than to wear away the pol- 'ish, but frequently it wears. into the leather itself. For the reason stated, therefore, the Everstiok rubber is not satisfactory unless it is worn upon a shoe to which it is fitted with more or less exactness. It is therefore necessary for the manufacturers of the heel part of the rubber.

provide a sandal rubber having all of the desirable qualities of the Everstick rubber, but which doesnot have to be so nicely fitted to the shoe on which it is worn; to provide, in other words, a rubber which will be adaptable to shoes differing very greatly in the thickness of their soles.

The invention consists of a sandal rubber having, near the upper edge of the low front part' of the upper, an external bead which is extended back to the heel portion of the upper,- in which bead a non-stretchable wire or cord. is embedded, said rubber having a high heeled portion, and a strap of variable length adapted to go over the instep of the shoe on which the rubber is worn. V

The invention, as illustrated in the accompanyingdrawing is hereinafter described, and the invention is definitely defined by the appended claims.

In the drawing Figure l is a side elevation of an overshoe in which the present invention is embodied. Fig. 2 is a sectional view showing the rubber, the shoe therein, said section being in the plane indicated by line 22' on Fig. 1; and Fig-l 3 is a section on line 33 on Fig. l.

The low. front part A of the upper of the rubber has an external bead a arranged at a suitabledistance, as shown, above the sole of the rubber, said bead extending around the toe and then back on both sides of the In this external bead a cord or wire B is embedded, which; cord or wire should be of substantially nonstretchable material. This bead is placed at such distance above the sole C of the rubber that, when the rubber is applied; to a shoe, this bead will be above the crease of the shoe and will engage with that part of the shoe upper ;which is inclining away from the adj acentedge of the sole. Those familiar with this art will under-' stand that in making the described rubber it is to be made upon a last, the toe part of which curves upward approximately, as shown by dotted lines in Fig. 1. If, when so curved up at the toe, the upper of the rubber stands at approximately right angles to the sole thereof, the last may be easily removed. hen, thereafter, the rubber is bent down at the toe, as it is when in use, the upper A will incline inwardly so as to overhang the part of the upper just above the sole as shown.

The heel part D of the rubber will at its upper edge be inclined forward so as to fit the heel of the shoe.

E represents a strap which is a part of the upper of the rubber and is arranged so as to go over the instep of the shoe. This strap must be of variable length. As shown this result is attained by making the strap elastic.

. When this rubber is on a shoe, the strap prevents the heel part of the rubber from coming off, and the cord prevents the low front part of the upper from assuming any position except the inwardly inclined position shown and above referred to; and therefore the front part of the upper is held on.

In order to give a suitable anchorage to the strap E, and to prevent the strap from distorting the rubber, a fabric strip G is placed between the outer rubber layer and the lining H, being vulcanized to the former, this fabric strip lying in the shankpart of the upper and of the sole ;-that is to say, it is fixed to the sole as well as to the upper. The strap E is practically a continuation of the rubber layer of the upper, and the upper ends .of the strip Gr extend into that part of the strap on both sides of the overshoe, when it extends from the upper.

Having described my invention, 1 claim:

1. A sandal rubber, the upper part of which is low in front and high at the heel, combined with a cord applied externally and extending along the sides and around the toe of the low front part of said rubber, thereby leaving the inside of the low front part smooth, and said rubber having an elastic strap which is adapted to go over the instep;

2. A sandal rubber, the upper of which is low in front and high at the heel and which has a strap of variable length adapted to go over the instep of the shoe to which the rubber is applied,the low front part of said upper having an external bead extending around the toe and along both sides thereof to points near the heel, said bead leaving the interior of the rubber smooth and being at such distance above the sole of the rubber that it will be well above the crease of the shoe on which the rubber is adapted to be worn,-there being a cord embedded in said external bead and being substantially coextensive therewith as to length.

3. A sandal overshoe having a sole and an upper high at the heel and low at the sides and toe, said upper comprising an outer layer of rubber and an inner fabric lining, an elastic strap adapted to pass over the instep of an inserted shoe and joining the outer rubber layer at each side of the upper, and a fabric strip arranged beneath the lining and united to the sole, to the upper, and to the end portions of the strap.

In testimony whereof, I hereunto my signature in the presence of two witnesses.
