COMPLETE SPECIFICATION.
An Improved. Embossed Composition Fabric.
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 The Pantasote Leather Company, a Corporation incorporated under the
Laws of the State of New Jersey, of Passaic, in the County of Passaic, and State
of New Jersey, United States of America) 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 a composition fabric which is embossed in imitation of
leather or otherwise.
The object of said invention is to build up a composition fabric in such a manner
that the surface may be suitably embossed and cannot afterwards be stretched out
to obliterate the embossed design.
The invention is fully illustrated by the accompanying drawing, in which
Figure shews a face view of a portion of said fabric having an embossed
surface and shewing the several layers which form the combination;
Figure 2 is a cross-section on the plane of line 2-2, Figure 1, and
Figure 3 is a cross-section of a modification of the improved fabric.
Similar letters of reference denote similar parts in all the figures.
The improved fabric of this invention consists of four thicknesses, a b d and e.
The lower of these, «, is of stout cloth, preferably heavy and coarsely woven.
Upon this foundation cloth a is spread a layer, b, of gum composition. This com-
position may be any well known gum compound used for making imitation leather,
or it may be vulcanized india-rubber, gutta-percha, or the like.
The gum bis
spread, in quite a considerable thickness, while in a plastic state, over the cloth a.
Upon the surface of this composition is laid another layer of cloth, this cloth
being preferably much more closely woven and much finer than the cloth layer a.
Upon the cloth d is spread another very thin layer of gum composition e which
will hide the grain of said layer of cloth d. The fabric thus far explained is next
embossed by a suitable embossing tool which, owing to the softness and com-
paratively greater thickness of the layer of gum, produces its impression in the
upper layers e d and while the lower layer a remains flat.
It will be seen that in use the lower unembossed fabric a will prevent the
stretching out of the upper layers and that the indentations therein will be clearly
preserved, thereby giving a permanency to the embossed exterior surface. When
the thickness of gum is less, as in Figure 3, the lowermost sheet a may respond
to an immaterial degree to the action of the embossing tools, but even in this case
it will remain substantially unembossed and prevent the stretching out of the
embossed design. The fabric produced according to said design will have the
appearance of natural leather, and will be waterproof, but cannot be stretched out
of shape and consequently will be very durable.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is ;-
1. As a new article of manufacture, the embossed composition-fabric herein
described, the same consisting of the bottom sheet a of fabric, of the layer 6 of
gum-composition placed upon said fabric, of the fabric d placed upon said com-
position-layer b, and of the uppermost layer e of gum-composition, all as herein
shewn and described.

page_text: 2. The improved embossed fabric herein described, the same consisting of the
embossed upper layers bde and of the unembossed bottom fabric a, the layer d
being of fabric and the layers and e of gum-composition, substantially as herein
shewn and described.
3. As a new article of manufacture, the embossed composition-fabric herein
described, the same consisting of the bottom sheet 'a of fabric, of the layer of
gum composition placed upon said fabric, said layer being sufficiently heavy to take
up the embossed design of the fabric d that is placed upon said composition-layer b
before the same was embossed, and of the uppermost coating e of gum-composition,
all arranged to have the embossing mainly on one side of the fabric, substantially
as herein shewn and described.
