Year: 1857

page_text: LETTERS PATENT to David Carter, of Honley, near Huddersfield, in the
County of York, Machine Maker, for the Invention of "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR CLEANSING THE WASTE OF WOOLLEN OR OTHER
FIBROUS MANUFACTURES, OR FOR RECOVERING THE WOOL OR OTHER FIBRES.
FROM SUCH WASTE SUBSTANCES OR MATERIALS."
Sealed the 3rd September 1857, and dated the 15th May 1857.
PROVISIONAL SPECIFICATION left by the said David Carter at the
Office of the Commissioners of Patents, with his Petition, on the 15th
May 1857.
I, DAVID CARTER, of Honley, near Huddersfield, in the County of York,
Machine Maker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CLEANSING THE WASTE OF
WOOLLEN OR OTHER FIBROUS MANUFACTURES, OR FOR RECOVERING THE WOOL OR
OTHER FIBRES FROM SUCH WASTE SUBSTANCES OR MATERIALS," to be
to be as follows:-
My Invention consists in the use or employment of a hollow cylinder, the
periphery of which is perforated or formed of gratings of any suitable size
and form, such cylinder being capable of rotating upon its axis. Also in
the employment of another cylinder, whose periphery or external surface
is studded with teeth, prongs, or points, suitably arranged, such cylinder
being capable of rotating upon its axis within the first-named cylinder, and
concentrically therewith, but in a contrary direction.
Doors or openings are provided in the outer cylinder to supply the sub-

page_text: stances to be operated upon by the teeth or points of the inner cylinder, the
perforations of the former allowing the dirt to escape as the cylinders
revolve,
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said David Carter, in the Great Seal Patent Office on the
14th November 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
CARTER, of Honley, near Huddersfield, in the County of York, Machine
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of May, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said David Carter, my executors, administrators, and assigns, Her special
licence that I, the said David Carter, my executors, administrators, and
assigns, or such others as I, the said David Carter, my executors, admi-
nistrators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
CLEANSING THE WASTE OF WOOLLEN OR OTHER FIBROUS MANUFACTURES, OR FOR
RECOVERING THE WOOL OR OTHER FIBRES FROM SUCH WASTE SUBSTANCES OR
MATERIALS," upon the condition (amongst others) that I, the said David
Carter, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, David Carter, being executor for the said David
Carter, deceased, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the
Drawings hereto annexed, and to the figures and letters of reference thereon
(that is to say):

page_text: My Invention consists in the use or employment of a hollow cylinder, the
periphery of which is perforated or formed of gratings of any suitable size and
form, such cylinder being capable of rotating upon its axis. Also in the
employment of another cylinder whose periphery or external surface is studded
with teeth, prongs, or points suitably arranged, such cylinder being capable of
rotating upon its axis within the first-named cylinder, and concentrically
therewith, but in a contrary direction.
Doors or openings are provided in the outer cylinder to supply the sub-
stances to be operated upon by the teeth or points of the inner cylinder,.
the perforations of the former allowing the dirt to escape as the cylinder
revolves.
In the accompanying Sheet of Drawings, on which similar letters refer to
the same parts in each Figure, Fig. 1 is a front elevation of a machine
constructed according to this Invention, and Fig. 2 is an end elevation of the
same. A represents the hollow cylinder, the periphery of which is perforated
or has openings or gratings formed by the insertion of the iron rods a, a, at
suitable distances apart; B, the framing for supporting the said cylinder on
the bearings b, b, in which it is capable of rotating upon its axis; Fig. 3 is a
longitudinal section of the cylinder A, shewing another or inner cylinder c, the
surface of which is studded, or partly so, with the teeth, prongs, or points c, c,
suitably arranged, which cylinder is supported and capable of rotating in the
hollow axis of the cylinder A. D is a small toothed cylinder for stripping or
cleansing the teeth of the large cylinder as it rotates, driven by the pullies
and strap e, from the shaft of the cylinder c. Fig. 4 is a cross section of.
the cylinders A, C and D, shewing their relative positions. The cylinder A
receives motion from and is caused to rotate in a contrary or reverse direction
to the cylinder C by means of the gear wheels f, and the pullies and strap g,
which are also capable of being thrown in or out of gear with each other by
the lever h, and catch box i, so that the rotation of the hollow or outer
cylinder A may be stopped, whilst the motion of the other cylinder C, and also
the stripper D, may continue; K is a door or opening in the outer cylinder,
through which the materials or substances to be operated upon are supplied
and removed. It will be clearly seen that as the inner cylinder rotates the
teeth will carry any materials or substances round with it, forcing the same
rapidly against the outer cylinder, which rotates in a contrary direction, and
thereby severing and recovering the fibrous substances from the dirt, which
dirt is driven through the gratings, the small cylinder stripping and preventing
the teeth of the large cylinder from clogging, which also assist in keeping the
substances open during the operation.

page_text: Having thus fully described the nature of the said Invention, and the
manner in which the same is to be performed, I would have it distinctly
understood that I do not confine myself to the precise details herein set forth;
but what I claim as the Invention, and which to the best of my knowledge
and belief has not been hitherto used within the realm, is, the use or employ-
ment of two cylinders, in manner and for the purposes herein described and
illustrated in the accompanying Sheet of Drawings, or any modification in
construction and arrangement thereof.
In witness whereof, I, David Carter, being executor for the said David
Carter, deceased, have hereunto set my hand and seal, this Thirteenth
day of November, in the year, of our Lord One thousand eight hundred
and fifty-seven.
Signed, sealed, and delivered by the
within-named David Carter, in the
presence of
CHARLES CARTER.
DAVID CARTER. (L.S.)
