sTAlRfPAD.

SPECIFICATION forming part of Letters Patent No. 446,213, dated February 10, 1891.

Application filed October 31 1890. Serial No. 369,930. (No model.)

To all whom t may concern.:

Be it known that I, TIMOTHY SHELDo-N SPERRY, a citizen of the United States, residing at Flatbush, in thereounty of Kings and State of New York, have invented new and useful Improvements'in Stair-Pads, of which the following is a specification.

I have improved the Velastic pad for protecting stair-carpets from wear by providing such pad with a bottom board 0f inelastic material, as a means of preventing the pad from being bent or doubled lengthwise outof form and as a ineansof gagingthe bendingof ilexible inelastic strips, secured crosswise to said board, to form the nose at the edge of the pad for holding it over the nose of the step. For thisppurpose I provide a slab 0f s'Jme inelastic material, such as straw-board, and Ysecure flexible metal strips across it at intervals, so that it serves as a gage for bending the ends of the metal strips over its jedge to form the pad-nose perfeetlystraight-and uniform along the edge of the pad to cause it to fit and hold it straight and even at the nose of the step.

The accompanying drawings illustrate my improved stair-pad, in which- Figure l is a vertical cross section of the pad as applied on a stair-step. Fig. 2 isa longitudinal section of the same, and Fig-3 shows the bottom gage-board and its noseforrningstrips bent in relation to the edge of said board in forming the nose at the edge of the pad.

The pad is made of any suitable fabric casing a and a filling of cotton-bolting or other elastic filling b. Within this casing, at the bottom thereof, the gage-board c is placed, so that the edges d of its two longest sides are equal in length t0 that of the pad, and its width is suiciently less than that ofthe pad to form the gage for the nose-bend at both edges of the pad. I make this gage-board sn'fliciently thick to render it stiif erosswise, so that it cannot be easily bent in the direction of its length. Across the upper surface 45 of this gage-board I secure at suitable intervals strips of sheet metal e, so that their ends e project equally beyond both edges of the board. The ends of these metal strips are provided with holes f, by which they are fast- 5o ened to the edges of the casing, preferably bv eyelets g. I prefer, also, to secure the metal strips to the board by eyelets h. When these metal strips are thus secured to the edges of the easing, their projecting ends can be bent 55 under along the edge of the board, and thus the latter forms a gage to make an even and uniform bend along the edge of the pad.

I use strips about nine inches wide and make them of galvanized iron, so that they 6o can be bent to form the nose and straightened out again. rlhese strips may project at one end only of the board.

I claim as my improvementl. An'inelasticstair-pad base provided with 65 flexible metal-strip t0ngues,substantially as described, whereby the pad may be secured in position by said tongues, which when bent over the edge of said base serve as hooks over and engaging with the nose of the stair-tread. 7o

2. A stair-pad consisting of a fabric casing inclosing an elastic filling, and a straw-board having metal strips secu red thereto crosswise, projecting beyond its opposite edges, and having holes in their ends, substantially as de- 75 scribed, for the purpose stated.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

TIMOTHY SHELDON SPERRY.
