IMPROVEMENTS IN ENGINES FOR CARDING COTTON & OTHER FIBROUS MATERIALS
Year: 1864

page_text: LETTERS PATENT to Joseph Bickerton, of Oldham, in the County of
Lancaster, Engineer & Machinist, for the Invention of "IMPROVEMENTS
IN ENGINES FOR CARDING COTTON & OTHER FIBROUS MATERIALS."
Sealed the 23rd September 1864, and dated the 1st April 1864.
PROVISIONAL SPECIFICATION left by the said Joseph Bickerton at the
. Office of the Commissioners of Patents, with his Petition, on the
1st April 1864.
I, JOSEPH BICKERTON, of Oldham, in the County of Lancaster, Engineer &
Machinist, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN ENGINES FOR CARDING COTTON & OTHER FIBROUS MATERIALS," to be as
follows:-
This my Invention relates to a new combination of mechanism for combing
off the fibrous material from the doffers of carding engines; and the improve-
ments consist principally in the working of a double crank in a pair of metal
steps, the said steps working in slides connected with the comb shaft. The
rotation of this crank (by giving rapid oscillatory motion to the slides) causes
the required motion of the comb shaft; the said crank is caused to rotate by
means of a friction pulley in the axis of the main card cylinder working in
contact with a small friction pulley on the crank.
