page_text: LETTERS PATENT to George Lister, of Rivers, Dursley, in the
County of Gloucester, Manufacturer, for the Invention of "IM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR FEEDING SLIVERS OF WOOL
OR OTHER FILAMENTOUS MATERIALS TO CARDING AND CONDENSING ENGINES
OR MACHINES."
Sealed the 17th October 1868, and dated the 18th April 1868.
PROVISIONAL SPECIFICATION left by the said George Lister at the
Office of the Commissioners of Patents, with his Petition, on the
18th April 1868.
I, GEORGE LISTER, of Rivers, Dursley, in the County of Gloucester,
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR FEEDING SLIVERS OF WOOL OR
OTHER FILAMENTOUS MATERIALS TO CARDING AND CONDENSING ENGINES OR
MACHINES," to be as follows:-
My Invention consists in imparting a to-and-fro motion to the frame
carrying the slivers as well as a rotary motion to the paddles or feed
rollers in the following manner :-I take a shaft or bar extending across

page_text: the front of a machine and cut or form therein the whole or nearly the
whole length thereof a groove or slot; on this slotted or grooved shaft
or bar I loosely mount a mitre wheel carrying a feather which takes
into the slot or groove formed in the shaft; this mitre wheel is in gear
with a pair of wheels for communicating motion to the paddles. The
paddles are suspended from a shaft supported by a traversing bracket
and which embraces the mitre wheel on the slotted shaft. The slotted
shaft carries at one end a wheel and pinion on a shaft carrying a pulley,
to which motion is communicated by a strap or band. The other end
of the slotted shaft carries a wheel connected by two other wheels with
mitre wheels for driving the pulleys round which the traversing strap
passes and which is loosely connected to the bracket by a driving
stud. On motion being communicated to the machine the slotted rod
is caused to revolve, carrying with it the loose mitre wheel by reason of
the feather in the slotted shaft, and so a rotary motion is communicated
to the paddles, while at the same time the mitre wheel and with it the
bracket is carried along the slotted shaft or bar through the traversing
strap below, but which receives its original motion from the slotted rod.
The motion is continuous, and the wheels are never at any period of the
work thrown out of gear. The slivers of wool may be laid in parallel
layers or rows or diagonally as required, for it is only necessary to alter
the position of the slotted shaft or bar, that is, to set it parallel with the
feed apron, or diagonally therewith, to enable me to accomplish this.
The distance between the pulleys carrying the band can be varied so
that the length of the sliver laid on the feed apron may be regulated as
desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Lister in the Great Seal Patent Office on
the 17th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
LISTER, of Rivers, Dursley, in the County of Gloucester, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of April, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-first

page_text: year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said George Lister, Her special licence that I, the said
George Lister, my executors, administrators, and assigns, or such others
as I, the said George Lister, my 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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
FEEDING SLIVERS OF WOOL OR OTHER FILAMENTOUS MATERIALS TO CARDING AND
CONDENSING ENGINES OR MACHINES," upon the condition (amongst others)
that I, the said George Lister, 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, the said George Lister, do hereby declare the
nature of my 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 accompanying Drawings,
and to the letters of reference marked thereon, that is to say :-
My Invention consists in imparting a to-and-fro motion to the
frame carrying the slivers as well as a rotary motion to the paddles
or feed rollers in the following manner:-I take a shaft or bar
extending across the front of a machine and cut or form therein the
whole or nearly the whole length thereof a groove or slot; on this
slotted or grooved shaft or bar I loosely mount a mitre wheel carrying
a feather which works in the slot or groove formed in the shaft, which
mitre wheel is in gear with a pair of wheels for communicating motion
to the paddles. The paddles are suspended on a traversing bracket,
which is supported on the two cross shafts or bars, and which embrace
the mitre wheel on the slotted shaft. The slotted shaft carries at one
end a wheel and pinion on a shaft carrying a pulley, to which motion is
communicated by a strap or band. The other end of the slotted shaft
carries a wheel connected by two other wheels with mitre wheels for
driving the pulleys, round which the traversing strap passes and which
is loosely connected to the bracket by a driving stud.

page_text: Figure 1 of the accompanying Drawings is a front elevation, and
Figure 2 is a plan of so much of a carding engine as will be necessary
to illustrate the manner in which I prefer to carry my Invention
into effect; Figure 3 is a cross section of the same; similar letters of
reference refer to like parts in all the Figures.
a is the slotted or grooved shaft or bar extending across the front of
the machine and supported in bearings 6 at each side; the shaft or bar
may be slotted or grooved the whole of its length or only that portion
along which the traversing bracket travels; c is the mitre wheel fitted
with a feather which takes into the slot in the shaft or bar a. This mitre
wheel is embraced by the traversing bracket d as shown; e, e, are a pair
of wheels in gear with the mitre wheel c; fis a shaft carrying one of the
paddles or feed rollers g, and g¹ is the other paddle; / is a toothed
wheel on the end of the shaft a in gear with driving wheels i, i, which
are themselves in gear with mitre wheels k and communicating motion
to a pulley 7, round which a strap m passes to another pulley on the
opposite side of the machine; n, n, are slots formed in the frame, and
n', n', are nuts whereby the distance existing between the pulleys
carrying the band or strap m can be regulated, and it is by this means
that the length or width of the sliver to be laid on the feed apron is
regulated. The strap is provided with a buckle to adjust the necessary
length. o is a driving stud on the band or strap m, which is inserted in
and is free to travel in a slot p cut, or formed in the traversing
bracket d; q is the shaft along which the traversing bracket d travels;
r is a wheel on the shaft a in gear with a pinion, and s is a band wheel
on the pinion shaft round which a strap passes for communicating the
necessary motion.
The action is as follows:-On motion being communicated to the
wheel through the pinion and band wheels rotary motion is
transmitted to the slotted shaft a; the mitre wheel c is thus caused to
revolve by reason of the feather on it taking into the slot in the shaft a,
the mitre wheels communicate motion to the pair of wheels e, e, thence
to the shaft and paddles g, g¹, and between which the sliver is led
from a roller or guide above in the ordinary way. When the shaft or
bar a is caused to rotate by the driving pulleys the wheel h com-
municates motion to the driving wheels i, i, which through the
mitre wheels k drive the pulleys 1, 1, and strap m. As this strap m
passes round the pulleys 1, F, it takes the bracket d, d, and paddles
9, g, along with it by means of the driving stud o passing through the

page_text: slot p in the bracket d; as the bracket moves along the slotted shaft a
and its guide rod q, the sliver is laid on the feed apron x. The motion is
continuous, no throwing in and out of gear, for as soon as the bracket d
arrives at the end of its course the stud o travelling in the slot p passes
round the pulley and goes in the contrary direction, without in any way
retarding the rotation of the slotted shaft a or creating any jar or
hitch in the motion of the machine. The slivers may be laid in
parallel layers or rows or diagonally as required, for it is only necessary
to alter the position of the slotted shaft or bar, that is, to set it parallel
with the feed apron or diagonally thereto, as the case may be.
And having now described the nature of my said Invention and in
what manner the same is to be performed, I declare that I claim as
my improvements in machinery or apparatus for feeding slivers of wool
or other filamentous materials to carding and condensing engines,-
First. The employment of a slotted or grooved rod, shaft, or bar
carrying a mitre wheel with a feather thereon taking into the slot or
groove for communicating a rotary and reciprocating motion to the
paddles or feed rollers, substantially in manner described and illustrated
in the accompanying Drawings.
Second. The arrangement of wheels and apparatus for transmitting
motion from the slotted shaft or bar to the traversing bracket, sub-
stantially as described and illustrated in the accompanying Drawings.
Third. The arrangement described and illustrated in the accompanying
Drawings for altering and determining the length of sliver to be laid on
the feed apron.
In witness whereof, I, the said George Lister, have hereunto set
my hand and seal, this Third day of October, in the year of our
Lord One thousand eight hundred and sixty-eight
