Application filed May 31, 1887.

.To a/ZZ whom it may concern:

Be it known that I, TIMOTHY S. SPEERY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Stair-Pads, of which the following is a specification.

For the protection of stair-carpets I have produced an improved flexible pad :for the steps,whereby a cotton-formed pad has a stift holding-nose part formed by a curved strippreferably of straw paper-secured as a lining to the covering-case at the concave wall of said nose part. This construction holds the cotton padflat and smooth under the carpet, as the nose-forming lining-strip laps over and under the projecting edge only of the step. This gives a cheap pad with a cotton-formed body having acotton-formed nose part shaped and-stiffened by re-enforcing its concave-wall part only, having its outer convexsurface soft and yielding at the point of greatest wear upon the carpet, while affording an elastic support and protection for the carpet upon the step. The pad is made of any suitable muslin or cotton fabric to form a closure and covering for the elastic material, which may be of raw cotton or other loose elastic material, while the nose-holding part is held in curved form to fit the edge of the step by a strip of straw paper of sufficient thickness to give the required stiffness for its holding function and allow it to be shaped to t the nose of the step. This curved stiff-holding-paper part I prefer to secure by glue to the inner surface of the muslin cover, and I may use a re-enforcingstiffeningpaper sheet extending from the nose part through the elastic material of the pad, so as Serial No. 239,854. (No model.)

cover sewed around its edges. Before this is done, however, I take one or more strips of paper, preferably common straw paper, c, and mold or set it over a form, so as to shape it to iit over the nose of the step, and secure itpreferably by glue-to the inner side of the cover at the edge part, d, which is to form a base for the curved nose parteof the pad, and form thereby a stiff holding partin the fabric cover itself', over which the elastic filling is placed toform a yielding nose part for the pad over a paper stiffener,which forms onlya lining-strip of the cover. This lining-stiffener is thefull length of the pad,but need be only wide enough to lap over and under the nose of the step aud give a stiff hold for the pad uponthe step at this point, so as to keep the pad smooth and at under the tread of the carpet. To aid inkeeping the pad smooth and iiat it may be re-enforced by one or more layers of common straw paper, y, extending from the nose through the middle of its body, so as to divide the elastic filling into two or more layers, as shown in Fig. 3. This re-enforcing paper need not be as thick as the nose-strip, so that it will readily bend over the latter in laying it in place between the lling in making the pad; nor need it be attached to the pad-cover. The nosestiffening paper strip may be xed to the outer surface of the cover; but the re-enforcing paper strip when used must be loosely placed within the body of the filling, so as not to be in contact with the cover.

The pad may be stitched through at various points to hold it compact, and when completed forms a cheap article of trade which can be kept in good condition for long use.

I claiml. As an improved article of manufacture, a stair-pad consisting of a covering-case part, a body of elastic filling material, and a curved stiffening nose-forming strip secured as a lining to the covering-case part, substantially as described.
