PROVISIONAL SPECIFICATION.
Improvements in or applicable to Carding Engines.
We JOHN ROBINSHAW; Manager, of 12 Hough Lane and GEORGE SCHOFIELD,
Carder, of 7 Cleggs Terrace, Bilson Bridge both of Milview Rochdale and
JAMES HEAP, Woollen Manufacturer of Clift House near Rochdale all in the
County of Lancaster do hereby declare the nature of our said invention to be as
follows:-
This invention relates to that class of carding engines known as roller engines
and which are employed for carding cotton, wool or other fibrous materials.
22
The object of the invention is to prevent what is known as "plucking" and is
designed to enable the fleece of cotton as it is taken from the "rollers to the
"clearers to be delivered back again to the main cylinder in a more even and
regular manner than hitherto.
יי
22
For this purpose we propose to place a bar or rod at a convenient part on the
top side between each roller and clearer" all round the carding cylinder.
These bars or rods are mounted in suitable brackets attached to the "bend" of
the carding engine and are placed just between the rollers" and "clearers," and
as near as possible to the teeth thereof, without actually touching the same.
By this means the fleece of cotton as it is being delivered from the rollers to the
clearers comes in contact with the smooth surface of the rods or bars which prevents
it from flying out or "plucking," and hence a better yarn is afterwards produced
therefrom.
The rods or bars may be made of any suitable material, or of any section
required; or instead of the fixed and stationary rods we propose in some cases to
use smooth rollers which are caused to revolve by any suitable arrangement of
gearing.

COMPLETE SPECIFICATION.
Improvements in or applicable to Carding Engines.
We Joux ROBINSHAW Manager of 12 Hough Lane, GEORGE SCHOFIELD,
Carder of 7 Cleggs Terrace, Bilson Bridge, both of Milview Rochdale, and
JAMES HEAP Woollen Manufacturer of Cliff House near Rochdale, all in the
County of Lancaster, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
22
This invention relates to that class of carding engines known as "roller engines"
which are employed for carding cotton wool or other fibrous materials, and wherein
the carding is effected by means of "rollers" and "clearers" in combination with
the main carding cylinder.
23
<
The object of the invention is to prevent what is known as plucking" and is
designed to enable the fleece of cotton or other fibrous material as it is taken from
the rollers to the "clearers" to be delivered back again to the main carding
cylinder in a more even and regular manner than hitherto, whereby knobs or lumps
and other impurities are almost entirely prevented and a more even fleece obtained.
The nature of our said invention and the manner in which the same is to be

page_text: performed or carried into practical effect. will be readily understood on reference to
the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 is a front view, Fig. 2 a side elevation and Fig. 3 a vertical section of so
much of a roller" carding engine as is necessary. to illustrate the invention.
Figs. 4 and 5 are detached views hereafter referred to. a is part of the main
carding cylinder part of the "bend" or framing, c one of the "rollers" and
d one of the "clearers."
For the purposes of this invention we propose to place a bar or rode at a
convenient part on the top side between cach "roller and clearer "all round
the upper part of the main carding cylinder a as shown on the drawings.
These bars or rods e are mounted in suitable brackets attached to the "bend "b
of the carding engine, one of which brackets is shown detached and drawn to a
larger scale at Fig. 4. The lower end of the bracket is screwed and it is provided
with nuts g, g¹ so that it can be adjusted nearer to or further from the centre of the
main cylinder, and it passes through a slot in the "
« bend so that it can be adjusted
in the other direction towards the "roller" or the "clearer
" so that it can be
placed accurately just between the "roller" and "clearer" and as near as possible
to the teeth thereof without actually touching the same.
22
By this means the fleece of cotton or other fibre as it is being delivered from the
"rollers to the "clearers" comes in contact with the smooth surface of the rods
or bars e which prevents it from flying outwards in flakes or plucking" as it is
termed, and hence a better and more even yarn is afterwards produced therefrom.
In some cases we propose (instead of a rod or bar) to employ a split tube / as
shown at Fig. 5 fixing therein a brush or a strip of felt, india rubber,. or other
suitable material so that it projects beyond the surface of the tube and lies close to
the face of the "stripper" or "clearer teeth.
The rods or bars may be made of any suitable material (preferably of steel) and
of any section required, or instead of fixed stationary rods we propose in some
cases to use smooth rollers which may be caused to revolve.
Having now particularly described and ascertained the nature of our said inveu-
tion and in what manner the same is to be performed we declare that what we
claim is
39
First. The combination with the "rollers" and "clearers" of roller carding
engines, of adjustable rods mounted between the said "rollers and clearers
at the top thereof and as near as possible to the teeth without actually touching the
same substantially in the manner and for the purpose hereinbefore set forth and as
illustrated by the drawings annexed.
22
Secondly. The combination with the "rollers" and "clearers" of roller carding
engines of adjustable rollers mounted between the said "
"rollers and clearers
at the top thereof and as near as possible to the teeth without actually touching the
same, substantially in the manner and for the purpose hereinbefore set forth and as
illustrated by the drawings annexed.
