EDWARD JULES JOSEPH LECŒUR and JOHN MUIR HETHERINGTON, both of
Manchester, in the County of Lancaster. IMPROVEMENTS IN CARD CLOTHING AND
IN THE METHOD OF ATTACHING THE SAME."
-
Our Invention relates to the wire card clothing employed in the covering of
parts of apparatus employed in the carding of fibrous materials and to the method
of attaching such clothing to the said parts. According to the first part of our
Invention we attach a backing of calico, linen, or other suitable material to the
sheets or fillets of card clothing. This backing is by preference cemented to the
back of the sheet or fillet by means of caoutchouc or of india rubber cement, but
any suitable cement may be used for the purpose. We may apply more than
one layer of backing material to the sheet or fillet. The said backing covers or
encloses the backs of the wire staples and adds firmness to the wire teeth. The
said backing also facilitates the attachment of the card clothing in accordance with
the second part of our Invention. To attach the card clothing to the cylinders,
rollers, clearers, flats, or parts of apparatus we take the card clothing, backed as
herein aforesaid, and we glue or cement the back of the clothing to the roller, flat,
or part. One of the advantages resulting from this method of attachment is that
the ordinary margins or spaces required for the insertion and securing of the
ordinary nails or rivets are not required. This is of particular advantage in the
cases of flats, for the reason that the width of the carding surface may be increased
as compared with the width of the flat. Cards not backed may also be secured or
attached in the same manner, but we prefer to apply the backing preparatory to
the attachment.

EDWARD JULES JOSEPH LECŒUR and JOHN MUIR HETHERINGTON, both of
Manchester, in the County of Lancaster. "IMPROVEMENTS IN CARD CLOTHING AND
IN THE METHOD OF ATTACHING THE SAME."
Our Invention relates to the wire card clothing employed in the covering of parts
of apparatus employed in the carding of fibrous materials and to the method of
attaching such clothing to the said parts. According to the first part of our
Invention we attach a backing of calico, linen, or other suitable material to the
sheets or fillets of card clothing. This backing is by preference cemented to the
back of the sheet or fillet by means of caoutchouc or of india rubber cement, but
any suitable cement may be used for the purpose. We may apply more than one
layer of backing material to the sheet or fillet. The said backing covers or encloses
the backs of the wire staples and adds firmness to the wire teeth. The said backing
also facilitates the attachment of the card clothing in accordance with the second
part of our Invention. To attach the card clothing to the cylinders, rollers, clearers,
flats, or parts of apparatus we take the card clothing, backed as herein aforesaid,
and we glue
vi cement the back of the clothing to the roller, flat, or part. One of
the advantages resulting from this method of attachment is that the ordinary
margins or spaces required for the insertion and securing of the ordinary nails or
rivets are not required. This is of particular advantage in the cases of flats for the
reason that the width of the carding surface may be increased as compared with
the width of the flat.
To render this more clear we will refer to a Drawing which we have attached
hereunto and which represents an enlarged section of a flat having the card clothing
attached in accordance with our Invention. In the said Drawing a represents in
cross section an ordinary metal flat, b is the foundation in which are set the card
teeth c, and d is the said backing material. In the example a portion of the
foundation is wider than the rest so that the margins e, e, extend from each edge of
the card. In the cases wherein the said foundation is composed of several layers
of cloth cemented together the back layer may be wider than the other so as to
form the said margins. We cement the backing material to the back of the card
and we then cement the card, that is to say, the backing material to the flat, and
we also fold the margins e, e, over the edge of the flat and cement them securely
thereto. In some or in all cases we may dispense with these margins and as a
consequence with the folding of the foundation over the edges of the flat. To
render the attachment more secure we may rivet the clothing to the flat at a few
points. Cards not backed may also be secured or attached in the same manner, but
we prefer to apply the backing preparatory to the attachment.
Having now. fully set forth and indicated the nature of our said Invention and
the manner in which we carry the same into practical effect, we would have it to
.be understood that we claim,―
First. Cementing backing material to the sheets or filets of wire cards,
substantially as and for the purpose set forth and indicated.
And, Secondly. Cementing wire cards, sheets, or filets, either backed as herein set
forth or not so backed to carding engine rollers, cylinders, and flats.
In witness whereof, I, the said Edward Jules Joseph Lecœur, for myself
and on behalf of the said John Muir Hetherington, have hereunto set my
hand and seal, this Twenty-second day of June, in the year of our Lord
One thousand eight hundred and eighty.
