Year: 1861

page_text: LETTERS PATENT to Jacob Taylor, of Oldlanı, in the County of Lancaster,.
Cotton Spinner, and Robert King, of the same Place, Manager, for the
Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING :
COTTON OR OTHER FIBROUS MATERIALS TO BE SPUN."
Sealed the 23rd November 1861, and dated the 1st June 1861.
PROVISIONAL SPECIFICATION left by the said Jacob Taylor and Robert,
King at the Office of the Commissioners of Patents, with their Petition,.
on the 1st June 1861.
We, JACOB TAYLOR, of Oldham, in the County of Lancaster, Cotton Spinner,
and ROBERT KING, of the same Place, Manager, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
PREPARING COTTON OR OTHER FIBROUS MATERIALS TO BE SPUN," to be as
follows:-
Our Invention relates to improvements in the carding engine, and consists
of making an equilibrium comb or stripper by arranging the dofling comb so
as to be worked or moved at each end by arms or levers working upon studs
as centres, and the comb is held or supported in a straight line at both ends'
by rods attached to supports, connected to or forming part of the framework of
the engine, there being springs in connection with the rods to allow the yield-
ing required for the up-and-down motion of the comb, and equalizing its tension.
The arms or levers which work the comb are put in motion by rods con-

page_text: nected to cranks upon a separate shaft, which rods are jointed between the
studs and the comb, and thereby act with power and steadiness, and dispense
with the necessity of a shaft and tie rod.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jacob Taylor and Robert King in the Great Seal Patent
Office on the 30th November 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JACOB
TAYLOR, of Oldham, in the County of Lancaster, Cotton Spinner, and ROBERT
KING, of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of June, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Jacob Taylor and Robert King, Her special licence that we,
the said Jacob Taylor and Robert King, our executors, administrators,
and assigns, or such others as we, the said Jacob Taylor and Robert
King, 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 MACHINERY OR APPARATUS FOR PREPARING COTTON, OR OTHER FIBROUS
MATERIALS TO BE SPUN," upon the condition (amongst others) that we,
the said Jacob Taylor and Robert King, our exccutors or administra-
tors, by an instrument in writing under our, 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 ŸE, that we, the said Jacob Taylor and Robert King,
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 :-
Our Invention relates to improvements in the carding engine, and consists
of making an equilibrium comb or stripper by arranging the doffing comb so as
to be worked or moved at each end by arms or levers working upon studs as
.

page_text: centres. The comb is held or supported in a straight line at both ends by rods
attached to supports connected to the framework of the engine, there being
springs in connection with the rods to allow the yielding required for the up:
and-down motion of the comb, and equalizing its tension. The arms or levers
which work the comb are put in motion by rods connected to cranks.upon
a separate shaft, which rods are jointed between the studs and the comb, and
thereby act with power and steadiness, and dispense with the necessity of a
shaft and tie rod.
We also cause the comb to be straight and rigid by fixing to it a hollow
triangular or other shaped bar, having at each end a screw and nut, in order to
fix firmly the bar and comb to the arms or levers which move up and down.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying Sheet of Drawings, in which Fig. 1 is an end
elevation with a part in section; Fig. 2, a longitudinal elevation of one end;
and Fig. 3, a plan with a part in section of our improved mode of stretching
and giving motion to the comb or stripper for the doffing cylinder of the card-
ing engine; Fig. 4 is a plan of our application to the comb or stripper of a
hollow bar, for the purpose of keeping it straight and rigid; and Figs. 5 and 6
are side and top views of a part of the same, drawn about full size.
In Figs. 1, 2, and 3, the comb is shewn at a; it is fixed at each end to a
short spindle or holder b, fitting a boss c, fixed to each arm or lever d. To
each holder b is hooked a rod e, having a T-head f, which is passed through a
hole in the cap g, and afterwards turned at right angles, so that it may be held.
Each cap g fits over the end of a frame or shell h, with a cross piece i, having
screwed holes, into which are fitted the screws h, between the heads of which
and the cap are washers of india-rubber or other elastic material. The shell
or frame h is fixed to the table or frame of the engine, and when the screws
are turned, the comb is stretched, and as the comb moves up and down, the
india-rubber washers yield, to allow-the required vibration of the rods c. To
give the up-and-down movement to the levers d,and comb a attached to them,
we fix to each lever between the comb and centre of motion a stud m, and
connect it by a rod or link n to a crank o, formed upon or cut out of the sepa-
rate shaft p, at one end of which is the pulley q, connected by a strap r with a
Jarge pulleys on the card cylinder shaft t, or to any other driving pulley, by
which means, when the cranks revolve, the levers and comb are moved up and
down with power and steadiness.
In Figs. 4, 5, and 6, we represent our improved mode of keeping the comb
or stripper straight and rigid, by fixing to it a hollow bar. The comb is shewn
at u, at the back of which is soldered or otherwise fastened a triangular hollow

page_text: bar v, at the ends of which are soldered or fixed screwed pins w, which pass
through the arms or levers d, and are screwed up tight by the nuts y. In order
to adjust the comb to the doffing cylinder we fix the stud or fulcrum of each
arm or lever d, in a block g, held in the interior of the small frame a¹ fixed to
the table or frame of the engine. The block at the lower part fits the interior
of the small frame, but at all other parts it is smaller, so that it can be shifted
and adjusted to the required position by the set screws b', and afterwards held.
fast by the bolt or screw c'.
Having now described the nature and particulars of our said Invention, and
the manner in which the same is to be performed, we desire it to be under-
stood that wo claim,-
First, our improved mode of stretching the comb or stripper of the doffing
cylinder of carding engines by means of vibrating rods having heads in contact
with caps acted upon by screws in connection with washers of india-rubber or
other elastic material.
Secondly, the application to the back of the comb of a hollow triangular
or other shaped bar for the purpose of keeping the said comb straight and
rigid.
And, thirdly, our improved mode of working the arms or levers which carry
the comb by means of rods connected at one end to cranks on a separate shaft,
and at their other ends to studs fixed to the arms or levers between their
centres of motion and the comb, as all such improvements are herein described
and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Jacob Taylor, for and on behalf of
myself and the said Robert King, have hereunto set my hand and
seal, this Twenty-ninth day of November, in the year of our Lord One
thousand eight hundred and sixty-one.
Signed, sealed, and delivered by the
within-named Jacob Taylor, in the
presence of

JACOB TAYLOR. (L.S.)
