SHOE-PLATE.

Specification of Letters Patent No. 28,194, dated May 8, 1860.

To all whom it may concern:

Be it known that I, THOMAS W. PORTER, of Bangor, in the county of Penobscot and State of Maine, have invented a new and improved plate or cork for protecting the bottoms of the soles and heels of boots and shoes from wear and also for protecting the wearers thereof from slipping; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in an improved metallic concave plate or cork to be applied to the bottoms of boots and shoes to protect them from wear and to protect the wearers thereof from slipping;

In the drawings, Figure 1 is a perspective view of the plate or cork. Fig. 2 is a sectional view of the same.

The plates may be made of any suitable material, but I prefer cast iron. They may be made of any desired size but I prefer them from one half to three fourths of an inch in diameter and from one eighth to one fourth of an inch in thickness at the outside edge,as shown at e 6 Figs. 1 and 2. I make my plates or corks with a circular knife like rim or hearing, as shown at e 6 Figs. 1 and 2, and with a recess or concavity, as shown at c c, Fig. 1 and c Fig. 2. I fasten the plate to the boot or shoe by means of a screw (inserted in the hole through the plate, which is shown at a Figs. 1 and 2) in combination with the projections or points on the back of the plate as shown at i i Fig. 2, which points enter the leather and keep the plate from revolving and becoming loose. These plates or corks may be placed upon the bottoms of boots and shoes at various distances from each other according to the severity of wear to which the boot or shoe is to be subjected, but there should be at least three upon each heel and at least three rows lengthwise upon the sole.

Among the advantages of my improved cork or plate are its cheapness and durability, its adaptability to any size or form of boot or shoe, the eflicient protection it afiords thereto, while above all it is a perfect protection from slipping even on the smoothest ice, while by its peculiar form its bearings in all cases cross the fiber of the wood and prevent its injuring floors and carpets, and it is the only creeper that can be permanently worn without doing injury.

I claim as my invention- The concave plate or cork as hereinbefore described.
