Year: 1857

page_text: LETTERS PATENT to James Warburton, of Addingham, near Otley, in
the County of York, Manufacturer, for the Invention of "-IMPROVEMENTS
IN CARDING MACHINERY."

Office of the Commissioners of Patents, with his Petition, on the
16th April 1857.
I, JAMES WARBURTON; of Addingham,. near Otley, in the County of York;
Manufacturer, do.hereby declare the nature of the Invention for "IMPROVE-
MENTS IN CARDING MACHINERY," to be as follows:-
This Invention has for its object improvements in carding machinery;
for this purpose the carding cylinders are made to work with several
stationary surfaces of cards, but in place of such stationary card. surfaces being
arranged as heretofore, they are constructed as follows:-Opposite each part
of a card cylinder where it is: desired to have a stationary working card surface
there is an axis, on which is fixed a barrel or frame with several sides, and.on
each side is fixed a card surface suitable for acting as a fixed or. stationary.card
surface. The axles of these barrels or frames are at intervals caused to move
round a distance equal to that required to bring a fresh card surface of each
barrel or frame into position to work with the .card cylinder,. and thus.from

page_text: time to time to change the otherwise stationary card surfaces working with
the card cylinder. The dirt and refuse is removed from such card surfaces by
a brush or otherwise, when by the rotation of their axes they come opposite to
their respective brushes or other apparatus. When using carding engines
with spaced bands or fillets of cards around them, the product of each fillet is
passed through a Tweedler or Dyer's tube in order to put on a false twist, or to
condense the fibres.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Warburton in the Great Seal Patent Office on the
16th October 1857.
