MAT, STAIR, 0R STEP TREAD 0a PAD.

SPECIFICATION forming part of LettersPatent No. 334,994, dated January 25,-1886.

- Application filed November 11,1885. SerialNo. 152,411. (Nomcdcl.)'=- i To an whom it may concern.-

Be it known that I, AMADEE SPADONE, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Mats or Pads for Steps, Stairs, or Platforms, of which the following is aspecification, reference being had to the accompanying drawings.

My invention relates to that class of protective mats or pads which are usually applied to steps, stairs, or platforms, where, through constant use, hasty wear and tear is experienced, resulting in a continued necessity for repairs or renewal. Mats or pads of this kind have been made by forming projections or studs of uniform height on a plate of rubber .1? other. elastic ma.teria1, wl1ialnstWis-pro jected through perforations in a plate of metal, the rubber being placed at the bottom and a metallic covering over it to hold it in place. Mats have also been made by securing, separately, elastic buttons or studs of a uniform height in a floor or in a plate of wood or metal. In the first construction considerable trouble is met in repairs or changing, while in the second, as also in the first, the buttons or studs cutofl' or drag out in a short time. Both are found wanting for such reasons.

The object of my invention is to overcom these troubles and to economize as far as pos-- sible in thecost and trouble of such renewals of the mats or pads, as well as to do away with the present universal injury to the steps, stairs, or platforms arising from the driving of nails or tacks in new places at each renewal of such sheet-rubber treads or mats.

My improvements consist in the construction and combination of a frame-work or foundatiuu-plale of metal, porcelain,or equivalent material, within. the area of which are set,

. erected, 'or scattered, in a pattern or otherwise, hubs, bosses, or projections about or around which the india-rubbcr mat-s 0r pads are laid in sheets,- thus exposing a combined hard fixed surface and a compressible frictionsurface developing a tread not easily worn out and over which there can be no slipping or sliding.

Certain other improvements consist in spe cial means for retaining or holding in place such inlaid india-rubber mats or wearing-surfaces, where specially rough or hard ,usage is experienced. a

Other improvements consist inthe'fcombination of any or all of the severalpart-s' or details herein described or speeified.. -in their several connections and duties. :The rubber facing is laid flush with the hubs or bosses.

In the drawings, Figure 1 represents a tread 1 embodying my improvements as applied to stair purposes. The forward sideofthe framework is here returned over the edge of the steps as a protection. Such, return may be used or not, according to necessity or choice. Fig. 2 represents a sectional view of Fig. 1.

Fig. 3 represents a detail sectional view of a Y method of fastening or holding the inlaid rub- 6 represent detail views of a second method of fastening or holding the inlaid or surface The hubs, bosses, or projections may be formed or cast as a part of the frame-work or foundation, or, being made separate, may be fastened thereto, holding the inlaid or surface matting in place. The hubs, bosses, or projections may have letters cut, raised, or embossedthereon, or they may take any formsuch as round, square, triangular, or polygonaccording to choice. The combination of these letters or the metallic bosses may develop a name or convey information, according as arranged.

Similar letters of reference designate like parts in all the figures.

In the construction of thisimproved mat or pad I form a frame-work or foundation-plate, A, of metal, mineral, porcelain, or equivalent material, havingza protecting border or outline of continuous or. divided projections, within which the inlaid rubber material or facing is held or laid. \V-ithiu the area of ing 0. This frame-work or foundation, A I:

permanently fasten to the step, tread, or plat metallic bossesor projections sticking through and holding the rubber faeingin placeagainst .the thrust of the feet in passing over. In

most cases, if carefully laid and fitted to place, no special fastening or retaining appliances willbe required, but where, through heavy usage or stealing, fastening may be considered necessary, the 'hubs or bosses may be shaped as represented at a in Fig. 3, and the facing or inlaid rubber forced into place; or the bosses may be specially fastened with screws or equivalent methods gripping the sheet facing in place. A less fixed method is represented in Figs. 4, 5, and 6. v

' Clipped portions 0 are forced into slots or holes located-beneath thchubs, border, bosses,

' or projections, as shown.

Such mats o'r pads may be used upon the steps of cars, carriages, on shipboard, in public thoroughfares, and the like.

What I claim as new, and desire to secure by Letters Patent, is-

l. A mat or pad'for steps, stairs, or platforms, consisting of a framework or foundation having hubs, bosses, or projections withiu'its area, about which hubs, bosses, or projections a facing of rubber is inlaid exposing a combined hard hub or boss surface and a surrounding compressible surface, substantially as set-forth. I

2. In a mat or pad for steps, stairs, or platforms, the combination of a frame-work or foundation provided with hubs, bosses, or projections, and a removable facing of rubber in serted or inlaid within the immediate area of the frame-work or foundation, and through which the hubs, bosses, or. projections protrude, substantially as set forth.

3. In a mat or pad for steps, stairs, or platforms, the combination'of frame-work or foundation A, hubs, bosses, or projections B, and the removable pad or mat G, substantially as .shown and described.

described. AMADEE SPADONE.
