v RUBBER SHOE. No. 296.453. Patented Apr. 8, 1884..




SPECIFICATION forming part of Letters Patent No. 296,453, dated April 8, 1884-.

Application filed December 22, 1881. (No model.)

To all? whom it may concern:

Be it known that I, FREDERICK RICHARD- SON, of the city and county Providence, and State of Rhode Island, have invented a new and useful Improvement in Rubber Shoes; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

The object of this invention is to protect the rear portion of the heel of a rubber shoe by means of a metallic wearing-surface, and to prevent the rapid wearing of this portion of the shoe.

The invention consists in the peculiar form of the wcaring-suriace, and the manner in which the same is embedded and secured in the heel portion of the shoe, all of which will be more fully set forth hereinafter, and pointed out more particularly in the claims.

Figure l is a perspective view of a rubber shoe, the rear portion of the heel of which is provided with metal wearing-points. Fig. 2 is a perspective view of one of the forms of metal wearing-points, the broken line showing the outline of the heel. Fig. 3 is a view of a modified form of metal wearing-points, the broken line showing the outline of the heel. Fig. 4 is a sectional View of the heel portion of a rubber shoe, showing the metal arms, from which the wearing-points extend, embedded in the rubber, and the wearingpoints extending to the tread of the heel.

in the drawings, A is the heel of a rubber overshoe.

B is a metal plate, consisting of arms radiating from a center, I). On the ends of these arms are placed wearing-points, the axis of which is at right angles to the arms. These wearing'points extend to the face or tread of the heel, when they are embedded in the same.

0 O areyearing-points placed on the ends of the arms B. These points do not extend quite to the edge of the heel, and are therefore surrounded by the rubber forming the heel, whereas the wearing points or surfaces D D extend to the edge of the heel and are surrounded by the rubber forming the heel on all sides, excepting the edge of the heel. In both cases, while each point serves as a sepa rate brace for holding the arms in position,

they together form the metallic guard for the edge of the heel.

protecting- These metal heel-protectors are embedded between the strip of rubber forming the sole and the strip forming the heel before the shoe is subjected to the process of vulcanization, and are thereby firmly secured, as in this process the sole and heel become as one mass.

By the use of the widely-separated single arms the plate is allowed to be more thoroughly embedded in the heel than heretofore, and a less weight of metal is necessary. The separated wearing-points are less liable to slip upon pavements and ice than a continuous metal rim, and present the appearance of nails driven into the heel, so that it is much more sightly than the continuous rims heretofore projecting and forming the rear and sometimes the entire margin of the heel. A heel with these separated points and intervening portions of rubber are also less noisy in walking than the old styles of heels with long metal wearing-surfaces.

1 am aware that metal heel-plates have been formed with radial arms connecting with a common external continuous rim, and that such rim has been provided with lugs projecting laterally or radially, so as to be embedded in the rubber of the heel, for the purpose of holding the plate in position, while the continuous rim forms the wearing-surface. I do not claim such a heel-plate.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the heel of a rubber shoe, of the radial singlemetallic arms B, separated by intervening spaces and united 0 only at their inner ends, said arms being enibedded in the heel, and having their outer ends provided with wearing-points extending through the tread-surface of the heel, and separated by intervening portions of the rubber, 5 substantially as described.

2-. The metallic heel protector consisting of the single arms B, radiating from and united only by the center piece, I), and provided at their outer ends with points projecting at right angles to the. plane of the arms, substantially as described.
