Schofield Whitworth at the Office of the Commissioners of Patents, with
their. Petition, on the 22nd August 1867.
We, HENRY HIGGINS, of Salford, in the County of Lancaster, Machine
Maker, and THOMAS SCHOFIELD WHITWORTH, of the same Place, Manager,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS MATERIALS FOR SPINNING,"
to be as follows: —
Our Invention relates, firstly, to those carding engines in which a series of
flats is mounted upon a travelling chain, and consists in an arrangement
whereby the grinding of the flats is regulated by the surfaces which register
them when they are in operation for carding. The aforesaid surfaces are, as
is well known, turned-over when being ground, and we propose to cause their
registering surfaces to travel in contact with a template or shaper which
elevates or depresses the grinding roller accordingly as each card requires the
removal of more or less wire. The template or shaper we propose consists of
revolving curved teeth connected with the axis of the grinding roller. In such
cards as aforesaid, but in which the flats travel back, we employ a stripping
roller for clearing them, which roller also acts as a worker with the licker in,.
and is then stripped by the cylinder.
Secondly. We attach the chain which carries the flats to one side thereof
nstead of to the middle as is usual.

page_text: Thirdly. Our Invention relates to carding engines in which the flats are
moved forward and are individually carried back. In machines of this class
we cause the flats to pass in contact with stripping and grinding surfaces,
and we propose to use a stripping and grinding arrangement similar to that
for which Provisional Protection has been granted to James Higgins, dated
April 11th, 1867, No. 1079.
Fourthly. Our Invention consists in a method of supporting top cards or
flats. For this purpose we cause them to rest upon "bends." which are
carried by the axis of or are otherwise connected with the carding cylinder, so
that the whole may be capable, of moving bodily.
Fifthly. Our Invention relates to a method of adjusting flats in reference to.
the working cylinder. For this purpose we mount them in brackets resting
on the "bends," and within which brackets they are capable of being moved
upward or downward, and of being adjusted in any required position by means
of screws.
Sixthly. Our Invention relates to a method of mounting rollers and clearers.
For this purpose we form spaces in the bends within which we place blocks
constituting bearings, and adjust them by screws or similar means.
Another part of our Invention relates to the slubbing or roving frame, and
consists in methods of adapting the flyer to the spindle. For this')
form a parallel tube upon the flyer which slips over. the spindle and rests upon
a shoulder formed thereon..
purpose we
By another method we extend the collar or tube to the top of the flyer,
which is provided with a portion of the spindle fitting into the said tube.or
collar, and forming a junction with the other portion of the spindle, so as to
'be coupled there with when in operation. If necessary we propose to adapt an
ordinary fastening to prevent the flyer from rising.
