Year: 1868

page_text: LETTERS PATENT to William Cooper, of Bradford, in the County of
York, Iron and Tin Plate Worker, for the Invention of "AN
IMPROVEMENT IN SLIVER CANS OR COTTON CANS."
Sealed the 24th November 1868, and dated the 27th May 1868.
PROVISIONAL SPECIFICATION left by the said William Cooper at
the Office of the Commissioners of Patents, with his Petition, on
the 27th May 1868.
I, WILLIAM COOPER, of Bradford, in the County of York, Iron and
Tin Plate Worker, do hereby declare the nature of the said Inven-
tion for "AN IMPROVEMENT IN SLIVER CANS OR COTTON CANS," to be as
follows:-
This Invention relates to the cans or receptacles employed in
connection with machinery for the carding or other processes
preparing wool, cotton, or other fibres for spinning to receive the

page_text: slivers of such fibrous substances as are produced by the machinery
employed for that purpose.
Heretofore the bottoms of these cans have been made of tin or other
material the same as the sides, with an iron hoop fixed thereon for
protection, but which hoops are frequently knocked off by ordinary use.
Now my improvement consists in constructing such cans with bottoms
of wrought iron in form of an inverted dish, the sides being of tin or
other material, as usual, rivetted and soldered thereto. By this im-
provement such cans or receptacles are rendered more durable than
heretofore.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Cooper in the Great Seal Patent Office
on the 27th November 1868.
