COMPLETE SPECIFICATION.
Improvements in Metallic Mats.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this invention (a communication to me from
abroad by William Chauncey Spelman of No. 59, East 59th Street, in the City,
County, and State of New York, United States of America, Manufacturer of Metal
Goods,), and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to cellular mats, made by preference, of corrugated con-
tinuous strips of metal, and consists in inserting pieces of rubber in the cells of said
mat, said rubber extending either across the middle or along the edge or edges of
the mat or being otherwise arranged in any of the mat openings which are selected
for the purpose.
The invention is illustrated in the accompanying drawings, forming part of this
Specification, in which
Figure 1 is a plan view of the improved mat.
Figure 2 a cross-section of the same, taken through line cc Figure 1.
Figure 3 a detailed view of the improved mat, shewing the rubber border inserted
at one end of the mat.
Figure 4 a cross-section of the same, through line kk Figure 3.
Figure 5 is a detailed view of the improved mat, shewing the rubber border inserted
at both ends and sides of the mat.
Figure 6 is a cross-section on line c¹ c¹ Figure 3.
Figure 7 a cross-section on line ¹ k¹ Figure 3.
Figure 8 is a view of a detachable frame which may be used to secure the rubber
border between the corrugated or scraping surface of the mat and the binding edge.
Figure 9 is a cross-section of a single block of rubber which illustrates one form
of accomplishing the invention.
Figure 10 a perspective view of the same; and
Figure 11 a longitudinal section of a series of these single blocks placed in position
to form the border.
Similar letters of reference indicate similar parts throughout the several views.
A represents the metallic strips composing the cellular or scraping surface of the
mat, which are shewn to be continuous corrugated strips; B the metallic rim surrounding
the mat, which is a hollow continuous rim; D D are rods running across the mat,
securing the scraping strips to the rim B; E is the rubber filling, which may be a
continuous band of rubber and inserted in cells or longitudinal openings of the mat
and retained therein, or else the filling may be of single blocks, as shewn in
Figures 9, 10, and 11, which are grooved at the edges to receive and conceal between
them the metal bars or the mat proper that hold said blocks in place, as in Figure 11;
G is a frame or partition of metal with projecting arms G' which may be placed along
the sides of the mat within the rim and held in position by the cells of the mat and
by riveting the arms GG¹ to the rim B. This frame or partition forms recesses
into which the rubber filling may be placed. In this improved mat, the blocks or
strips of rubber or analogous substance although shown only as applied to the border
of the mat, may be inserted in any of the cells or openings including those in the
corrugated part A of the mat, thus forming a combined scraping and elastic surface.
The advantage of thus having a rubber filling in the mat. is that the elasticity of
the rubber is utilised in scraping and that the rubber may be formed into letters to
spell the names of the owners of mats, or other names.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is ;-
1. A metallic cellular mat, provided with rubber filling E inserted in the cells of
the metal body, as and for the purposes set forth.
2. The rubber filling E for a metallic mat, the said filling being grooved at the
edges, substantially as and for the purpose herein shewn and described.
3. The combination, in a metallic mat having a rim B and metallic strips A, of a
partition G furnished with projecting arms G¹ and of the filling E of india rubber,
substantially as and for the purposes set forth.
4. The combination, with a metallic mat, of a frame G having projecting arms G¹
secured to the rim of the mat, as and for the purposes set forth.
5. The mat composed of continuous corrugated strips A and continuous hollow
frame B and of suitable filling in one or more of its openings, as described.
