IMPROVEMENTS IN CARDING ENGINES
Year: 1862

page_text: LETTERS PATENT to Jesse Brierley and Abram Brierley, of Spa Mill,
near Huddersfield in the County of York, Manufacturers, for the Inven-
tion of "IMPROVEMENTS IN CARDING ENGINES."
Sealed the 16th June 1863, and dated the 18th December 1862.
PROVISIONAL SPECIFICATION, left by the said Jesse Brierley and Abram
Brierley at the Office of the Commissioners of Patents, with their
Petition, on the 18th December 1862.
We, JESSE BRIERLEY and ABRAM BRIERLEY, of Spa Mill, near Huddersfield,
in the County of York, Manufacturers, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN CARDING ENGINES," to be as follows:-
This Invention relates to that class of carding engines known as "single
doffer condensers," and the improvements consist,―
Firstly, in placing a strip or ring of metal or other suitable material in
each space betwixt the rings of cards on the doffer cylinder, so as to.com-'
pletely fill up the spaces to near the points of the teeth and thus form divisions
of the cards, by which means wool or other fibre being carded may be
effectually divided and doffed in separate strips.
Secondly, the improvements consist in the employment of an additional
roller for supporting the rubbing belt, also an additional rubbing roller by
which a better slubbing is produced than heretofore.

by the said Jesse Brierley and Abram Brierley in the Great Seal Patent
Office on the 18th June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JESSE
BRIERLEY and ABRAM BRIERLEY, of Spa Mill, near Huddersfield, in the County
of York, Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of December, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year of
Ier reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Jesse Brierley and Abram Brierley, Her special licence that we, the
said Jesse Brierley and Abram Brierley, our executors, administrators, and
assigns, or such others as we, the said Jesse Brierley and Abram Brierley, our
executors, administrators, 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 CARDING
ENGINES," upon the condition (amongst others) that we, the said Jesse
Brierley and Abram Brierley, our executors or administrators, by an in-
strument in writing under our, or their, or one of our or 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 we, the said Jesse Brierley and Abram Brierley,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement, that is to say:-
The Invention relates to that class of carding engines known as single
doffer condensers, and the improvements consist,-
Firstly, in placing a strip or ring of metal or other suitable material in each
space betwixt the rings of cards on the doffer cylinder, so as to completely fill
up the spaces to near the points of the teeth, and thus form divisions of the
cards, by which means wool or other fibre being carded may be effectually
divided and doffed in separate strips.
Secondly, the improvements consist in the employment of an additional

page_text: roller for supporting the rubbing belt, also an additional rubbing roller by
which a better slubbing is produced than heretofore.
By reference to the accompanying two Sheets of Drawings our Invention
will be readily understood.
Fig. 1 (Sheet 1) represents in longitudinal elevation part of the doffer
cylinder about one-fourth full size, shewing the surface thereof divided into
rings of cards A, with strips or rings of metal B placed betwixt them, the tops
of which rings are slightly lower than the surface or points of the card teeth,
and Fig. 2 is a cross section of the same; Fig. 3 is part of a longitudinal
section; and Fig. 4 is part of a cross section drawn full size. The cylinder is
of cast iron, but may be of wood or other suitable material, with the surface
turned up true. The strips of cards A are sewed, or otherwise fastened end
to end, forming rings to fit the cylinder. The metal rings B are also formed
to fit to the surface of the cylinder, and are placed thereon alternately with
the rings of cards. At each end is a metal ring C fastened with screws to the
cylinder, holding the whole series of cards and dividing rings in a fixed
position, as it will be observed that the metal rings B are each formed with a
recess to fit on the card leather or card cloth, so as to fill up the space or fit
close to the card teeth and bind the card clothing to the cylinder. By means
of these dividing rings wool or other fibre being carded is effectually separated
or divided and taken off the swift in separate strips, which are afterwards
rubbed into slubbing.
The second part of our Invention is shewn at Fig. 5, which is an end
elevation of the rollers and belt for rubbing wool or other fibre into slubbing
as it is taken off the swift by the doffer in strips. D are the two ordinary
rollers with the endless belt or strap E thereon, and F is an additional roller
placed so as to support the belt in the middle in order that the two rubbing
rollers G and H may be employed instead of one, or instead of employing an
additional endless belt as heretofore. We also cover the rubbing rollers with
strips of leather coiled thereon side by side, and in some cases we roll such
strips into round rolls previous to placing them on the rollers, thereby forming
a grooved or beaded surface.
Fig. 6 (Sheet 2) is part of a longitudinal section of a condenser carding
engine in outline, shewing the application and arrangement of our improve-
ments.
I is the swift; J, the doffer; K, the fancy; L, M, the striping rollers;
N is a grooved roller; and D, E, F, G, H, are the rubbing apparatus as
previously explained; O, P, are the friction drums for driving the bobbius

page_text: or spools R, S, on to which the slubbing is wound; and T, U, are the traverse
guides.
In witness whereof, I, the said Jesse Brierley, for and on behalf of
myself and the said Abram Brierley, have hereunto set my hand and
seal, this Fifteenth day of June, One thousand eight hundred and"
sixty-three.
Signed, sealed, and delivered by the
within-named Jesse Brierley, in
the presence of
WM. TASKER,
Patent Agent,
Halifax.
