IMPRovRD RUBBER MAT.

To wnoM IT MAY coNcRRN;

Be it known that I, FREDERICK M. SHEPARD, of New York, in the county and State of New York, have invented certain new and useful Improvements in Mats; and I hereby declare the following to be a full, clear, and exact description of thesame, reference being had to the accompanying drawings, in which- Figure 1 is an isometricalperspective view of a mat, constructed in accordance :with my said invention.

Figure 2 is a. sectional elevation of the same on line A B in iig. 1.

Figure 3 is an isometrical perspective view'of a modified form of said mat.

Figure 4, a section of the' same on line O D in fig. 3. v

The object of my inventi'n is the production of a mat combining the advantages of an elastic scrapingsurface with the convenience of a detachable receptacle of the mud, dust, and other scrapings.

Rubber mats, as heretofore constructed, consisted of a. cellular grating made in one piece with a receptacle or pan, or 'of a pan or receptacle provided with projecting'studs or points, the latter acting as a scraping-brush.

Th'e objections attending mats; as heretofore'made,'aref First. When the cellular grating is used, it being much thinner` on the upper side than at the bottom, and also than the receptacle, itis more highly heated during the vulcanizing process, and consequently becomes more stili' and brittle, and is therefore morereadily worn out than the other parts of themat. l v

Second. When the points are used, inasmuch as they are exposed to great exure, unless they are made of very pure and therefore expensive rubber, they will be easily broken o' by the scraping of the feet thereon.

Y Third. In either case the dirt is apt to clog in between the projecting'pnrtsof the mat, a/.ndxthwndering s the cleaning of the mat diicult, and oftenimpossible, without the aid of water.

These and other objections attending the, old mats are obviated by my improvement.

To enableothers skilled in the art to make and use my invention, I will proceed to describe the manner in which the same is or may be carried into eil'ect.

The mat is composed 'of two parts, M and P. The former is a cellular web of uniform thickness throughout. I prefer to use hexagonal cells, with a border of quadrangular cells, the whole being of the usual width and length.

In connection :with the cellular mat, I use a pan or receptacle, provided with a flange or-border, snugly tting the cellular sheet. The pan P may be made of rubber, tin, papier-mache', or othersuitable material, and its border may or may not project above the upper surface of the cellular web.

In figs. 1 and 2, I have shown the cellular web, combined with a snugly-fitting tin pan, the flanges of which i project above the upper surface ofthe cells, so as to aord an'additional rigid scraping-surface.l

In igs. 3 and 4, a like mat and pan are shown, the flanges of the latter being below the surface of the cells.

I have described the mat constructed in a manner I deem most practicable, but I would observe that the receptacle need not necessarily be provided with a flange.v The lcellular rubber web may bexheld to a, tin or other plate by means of two or more projecting studs or tenons on the plate, tittingltwo or more corresponding cells in the web, so that the web cannot be moved oif the plate, while the scrapings will remain confined within the cells, provided the rubber web lit tightly on the plate.

Having thus described Patent, isl The combination of a cellular rubber web whether the same'be Banged or not.

i In testimony whereof, I have signed vmy name to this specification before two subscribing witnesses.v
