We JAMES :SCHOFIELD of River Street Rochdale in the County of Lancaster
Machinist and. JOSHUA HITCHON: of Spring Wood Mill Ramsbottom of the aforesaid
County Spinner and Manufacturer do hereby declare the nature of our said
invention as stated in above title and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
"
Our invention is to be applied to carding engines, which, are employed in the
carding of materials known as "hard waste cotton or "cop bottoms" and has for
its object to effectually divide; the material as, it is well known that, if the material
be not properly divided on the doffing cylinder of the machine, the result, is, that
the threads are damaged at the dividing roller situate at the front part of the
machine as is well known, as the material is delivered from the doffing cylinder.
In order that the details of our invention may be understood, and its made clear,
we have reference to the accompanying sheet of drawings.
Fig. 1 is a side elevation shewing our apparatus applied to the doffer of a
carding engine.
Fig. 2. is a front view of the same through A. A. shewing so much thereof as is
necessary to illustrate our invention.
Fig. 3. is an elevation of a roller which may be substituted or employed instead
of the apparatus as shewn in Fig. 1.
In a convenient position between the cylinder B and the doffing cylinder C. at
the underside, we provide a metal shaft D. in the direction of the length of the
doffing cylinder C, upon which we mount a series or number of circular metal
pieces E, concentric there with, having projections E¹ on their surfaces, which, may
be cut thereon or, may be fitted thereto, the projections E¹ as shewn in the
drawings are cut upon the surfaces or formed from the said pieces E, if desirable
we may employ a roller F see Fig. 3. of any suitable material, preferably of wood,
which shall have projections F¹ thereon to be formed from the said roller by means
of swelled or raised parts F1 or, by applying strips of material thereon, as for
instance, a cylindrical roller F may be provided with strips of leather, cloth, or
other suitable material, to form the raised parts F¹ as indicated in the drawings
Fig. 3. such strips may have their surfaces fluted, or plain, as it may be necessary

page_text: to adopt the circular pieces E, or wood roller F, with raised or swelled parts so as
to accommodate the various classes of material which may be carded or worked in
the machine. The circular pieces E, or raised parts F' formed upon the roller Fas
the case may be, are to be arranged upon the shaft D., or roller F, so that each
piece E, or raised part F¹, shall be opposite to, and engage with, a space G "ring
space" upon the surface of the doffing cylinder C, and situate sufficiently near the
surfaces of the rings or spaces, so as to act efficiently upon the material in the
machine when required, and, in a manner which we will hereafter refer to.
To the shaft D with the circular pieces E, or roller F as the case may be, a
rotary motion is to be imparted, which motion, may be imparted by any convenient
driving shaft, the use of the circular pieces E, or raised parts F¹ on the roller F, is
to keep clear the spaces G of the doffer C from any obstruction, the foregoing
description completes the details of this our said invention we will now proceed to
illustrate the mode of operation of the same as follows.
In the process of carding or working "hard waste cotton " it is well known that
the doffing cylinder frequently fails to effectually divide the material into
"slivers J," from the "web H," without the aid of an apparatus for facilitating
the division thereof, which, has hitherto been of a clumsy nature, the "slivers"
are sometimes more or less connected to each other by tenacious threads see Fig. 2;
upon such occurrence the threads must evidently lie across the path or transverse
to space or spaces G on the doffer C, in the event of which such objectionable
connecting threads or tenacious portions I are detected and operated upon by our
apparatus, at the part as indicated in the drawings, which being caused to rotate
quickly, removes the tenacious portions of the material, thus in this manner is
effected a complete division or separation, of the "slivers" which, are then
allowed in such condition to pass to the front dividing roller of the machine, which
roller, is then ennabled to perform its proper functions.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is,
1. The combination of the shaft D with 'any convenient number of circular
pieces E to be applied at any convenient part of a carding engine for the purposes
herein set forth and substantially as described and shewn in the annexed drawings.
hereunto,
2. The combination of the roller F with any convenient number of raised
parts F¹ to be applied at any convenient part of a carding engine for the purposes
herein set forth and substantially as described and shewn in the annexed drawings
hereunto.
