IMPROVEMENTS IN CARDING ENGINES
Year: 1862

page_text: LETTERS PATENT. to Simeon Lord, Machinist, and John Lord, Manager,
both of Facit, near Rochdale, in the County of Lancaster, for the
Invention of "IMPROVEMENTS IN CARDING ENGINES,"
Scaled the 28th November 1862, and dated the 22nd July 1862.
PROVISIONAL SPECIFICATION left by the said Simeon Lord and John
Lord at the Office of the Commissioners of Patents, with their
Petition, on the 22nd July 1862.
We, SIMEON LORD, Machinist, and JOHN LORD, Manager, both of Facit,
near Rochdale, in the County of Lancaster, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN CARDING ENGINES," to be as
follows:-
This Invention consists, first, in improved modes of stopping the motion of
the duffing cylinder and feeding rollers when a sliver is broken at any part,and
does not enter the can or coiler. From the shaft which drives the can or
coiler, we give motion by a worm and wheel or spur or bevil gearing to a
catch box, the loose part of which is forced out when the sliver breaks or
cannot enter the can or coiler by causing it to be held by a rod connected to
the trumpet or balanced lever. As the loose part of the catch box is moved
out it operates upon an incline or cam at one end of a double lever, the other
end of which releases a catch and allows the barrow handle to be lowered and
bring the pinion out of gear and stop the engine whenever there is a breakage
of the sliver without in any degree depending upon its tension.

page_text: Secondly, in an improved mode of working the doffing knife or comb. We
form in the doffing stock which holds the knife or comb a hole from end to
end, through which hole we pass a shaft, having fixed to it two or more
eccentrics which fit the hole so that when the shaft and eccentrics revolve an
eccentric movement is given to the knife or comb, which thereby strips
the cylinder in a very efficient manner withoun juring the card.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Simeon Lord and John Lord in the Great Seal Patent
Office on the 21st January 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SIMEON
LORD, Machinist, and JOHN LORD, Manager, both of Facit, near Rochdale, in
the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of July, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year
of Her reign, did, for Herseif, Her heirs and successors, give and grant unto
us, the said Simeon Lord and John Lord, er special licence that we, the
said Simeon Lord and John Lord, our executors, administrators, and assigns,
or such others as we, the said Simeon Lord and John Lord, 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, aud Isle
of Man, an Invention for "IMPROVEMENTS IN CARDING ENGINES," upon the con-
dition (amongst others) that we, the said Simeon Lord and John Lord, our
executors or administrators, 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 inanner 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 Simeon Lord and John Lord, 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) :-

page_text: This Invention consists, first, in improved inodes of stopping the motion of
the doffing cylinder and feeding rollers when a sliver is broken at any part
and does not enter the can or coiler. From the shaft which drives the can
or coiler we give motion by a worm and wheel or spur or bevil gearing to a
catch box on the upright of the coiler, thereby dispensing with wheels; the
loose part of the catch box is forced out when the sliver breaks or cannot
enter the can or coiler by causing it to be held by a rod connected to the
trumpet or balance lever. As the loose part of the catch box is moved out
it operates upon an incline or cain at one end of a double lever, the other end
of which releases a catch and allows the barrow handle to be lowered and
bring the pinion outof gear and stop the engine whenever thero is a breakage
or defect in the sliver without in auy degree depending upon its tension.
Secondly, in an improved mode of working the doffing knife or comb. We
form in the doffing stock which holds the knife or comb, a hole from end to
end, through which hole we pass a shaft having fixed to it two or more
eccentrics, which fit the hole so that when the shaft and eccentrics revolve an
eccentric movement is given to the knife or comb which thereby strips the
cylinder in a very efficient manner without injuring the card.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying Sheet of Drawings, in which Fig.1 represents
a front elevation of a carding engine and coiler, with our improved mode of
stopping the engine when a sliver breaks or is absent; Figs. 2,3,4,5,6, and 7
are detached parts of the same, Figs. 3, 4, and 5, being drawn to an enlarged
scale; and Fig. S is a side elevation of part of a carding engine, having our
improved mode of stopping thedoffer and feed rollers when the can or receiver
has received the fixed quantity of sliver from the coiie.
a are the delivery rollers from which the sliver comes from the doffer; bis
the sliver passing into the trumpet lever entering the top of the coiler, the
bottom part of which comes close between the calendar rollers of the coiler;
c is the trumpet lever at the end of which is attached a bent lever, shewn
enlarged in Fig. 3. In this bent lever we make a slot, and place it in a small
balance weight which can be set as required, to balance the weight of the
sliver passing through the trumpet end of the lever into the coiler. d is a
small rod hung on a centre at the end of the bent lever; this rod is so bent
as to enter the coiler as at e, and when any breakage or defect arises in the
sliver the balanced trumpet rises and the bent end of the rod d falls and
catches a notch on the catch box f, shewn enlarged in Figs. 4 and 5. This
catch box works on the upright shaft in the coiler, and when the rod d catches'
the notch on the catch box the bottom part is forced down. The bottom.part

page_text: has a flange which rests on the end of a lever, as shewn at g, Fig. 2.
This
lever works on a centre as at h. When the other end of this lever is forced
upwards by the forcing out of the catch box it is then relieved from a notch in
the cross lever k, Fig. 6; at the end of this cross lover is attached a cranked
lever hung at the centre, as shewn at l, Fig. 6, to which is attached one end
of a connecting rod m, Figs. 1 and 6, attached at the other end to the
barrow levern, Fig. 1, which carries the small wheel turning the doffer and
feed rollers; and when the lever at g, Fig. 2, is relieved from the notch,
the barrow lever drops and brings the small wheel out of gear with the doffer
and feed rollers, causing a foot lever at o, Figs. 1 and 7, to rise. When
the doffer and feed rollers are required to restart the foot is pressed on the end
of the lever o, which raises the barrow lever and wheel into gear with the
doffer, and also causes the cross lever k, Fig. 6, to slide till the lever
drops in the notch.
y, Fig. 2,
Fig. 8 is a side elevation of a carding engine shewing our improved method
of stopping the doffer and feed rollers when the can or receiver has received
the fixed quantity of sliver from the coiler. To the bottom in which the
coiler works we attach a lever p, working on a fulcrum 7, and carrying at the
other end a balance weight q, a connecting rod s catches the lever 9, also
shown in Fig. 2, so that when the can or receiver becomes filled with the
weight of the sliver required the receiver presses down the lever p, causing the
rods to raise the lever, which is released from the notch in the cross lever k,
and causes the barrow lever n to drop and bring the wheel out of gear,
thus stopping the doffer and feed rollers, they being restarted as before
stated.
In Fig. 8 we shew an end view of the means of working the dofling stock
or.knife. On the cylinder end of the carding engine we fix a large pulley
which works a small pulley near the doffer end by means of straps or bands,
on the side of which small pulley is fixed a stud or excentric t, to which we
attach a short connecting baru, one end of which fits on a stud at the bottom
of a short lever v, which is fixed to the end of the hollow doffing stock w,
which, when in motion, gives the required oscillating motion, we can thus
dispense with the excentrics in the hollow tube.
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
understood that we claim in carding engines,-
First, our improved mode of stopping the engine when a sliver breaks or
becomes in any way defective.
And, secondly, our improved mode of stopping the doffer and feed rollers

page_text: when the can or receiver has received the fixed quantity of sliver from the
coiler, as all such improvements are herein described and illustrated in the
accompanying Sheet of Drawings.
In witness whereof we, the said Simeon Lord and John Lord, have
hereunto set our hands and seals, this Twentieth day of January,
in the year of our Lord One thousand eight hundred and sixty-
three
Signed, sealed, and delivered by the
within-named Simeon Lord and
John Lord, in the presence of
