We, JOHN CROSSLEY and WILLIAM HEALEY of the Salford Card Works Brighouse
in the County of York, Card Manufacturers, do hereby declare the nature of this inven-
tion, 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 the foundation material or fabric employed in the manu-
facture of the cards and combs employed in the carding and preparation of silk, tow
and flax and for analogous purposes as distinguished from the cards employed in the
carding and preparation of cotton and wool. The cards and combs to which this Inven-
tion relates are constructed with teeth which are much larger and stronger than those
which are employed for carding cotton and wool and are subjected to heavier wear and
consequently require greater support. To meet this requirement the foundation
material has been made stronger and thicker, but it has hitherto failed to afford that
complete support for the teeth of the card which it is one of the objects of this
Invention to provide. Another object of our Invention is to secure greater durability
for the foundation of the cards and combs.
These Improvements consist in the manufacture or construction of the foundation
material or backing for the cards and combs employed in carding and preparing silk
tow and flax in such a nanner that the face of the foundation shall consist of a film
or layer of that particular dark coloured india rubber compound known in commerce
as "carbonised india-rubber." The foundation in other respects may be precisely the
same as, or similar to, those at present in use or it may be of any convenient and
suitable material or materials. The film or facing of carbonized india rubber is
applied and secured to the face of the foundation material by means ordinarily
employed and well understood by Manufacturers of card foundations. By the "face
of the foundation we mean that surface which is next to the work when the card or
comb is in use and which is therefore the nearer surface to the points of the teeth.

page_text: We are aware that India rubber has already been used to face card foundations and
we therefore desire it to be understood that we do not make any general claim to the
use of this material nor do we make any claim for carbonised rubber for facing any
other foundation material than that or those hereinbefore set forth.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is :-
A foundation for the cards and combs employed for carding and preparing silk.
tow, and flax and for analogous purposes, having a facing of carbonised indiarubber
substantially as and for the purposes hereinbefore described.
