I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN MACHINES FOR CARDING FIBROUS MATERIALS
to be as follows :—
"
This invention relates to machines in which cotton, wool, or other fibrous
material may be readily carded; and the invention comprises improved means for
raising the smooth roller near the rear end of the machine away from the needle
roller, without removing the said smooth roller from the machine; the invention
further consists in the employment of a series of saw-teeth bars arranged in con-
nection with the breaker roller, the carrier roller and the licker-in for the purpose
of combing the fibres and freeing them from dirt and other extraneous inatter; and
in the combination and arrangement of parts hereinafter fully set forth.
The general construction of the frame, the main cylinder and arrangement of the
workers and strippers is similar to that of well-known machines of this class.
According to the said invention I provide a lap-roller from which the lap is
unrolled and delivered onto a shell-plate, which is curved upwards at its forward
end. The fibre passes from the shell-plate, under the feed roller, from which it is
taken up by the needle roller, which latter combs the fibres and removes from them
the heavy dirt, seeds and sand. The smooth roller serves to press the fibre upon
the needles of the needle roller.
The smooth roller is journalled in the ends of levers or arms which are
fulcrummed on the axis of the needle roller. The arms or levers are connected
together at their outer ends by a rod or cross bar.
To the centre of the said cross bar is attached a bar or rod which extends to the
rear of the machine and is provided at its outer end. with a handle, so that, should
the fibre become packed between the feed roller and the needle roller, the smooth
roller can be thrown upward away from the feed roller by drawing out the handle-
rod, thus allowing a space for the operator to loosen the lap or remove it from the
machine, without stopping the machine.
A breaker roller is provided upon which the fibre passes from the needle roller.
The said breaker roller is caused to run at greater speed than the needle roller, the

page_text: latter being driven by means of gearing connecting with the feed roller, which is
slowly rotated by means of a gear wheel engaging with a bevelled gear on a shaft
extending from near the front end of the machine and operated as hereinafter
stated,
The breaker roller passes the fibre over a series of saw-teeth bars, which comb it
and remove the dirt &, allowing the dirt to fall down between the saw-teeth bars.
The fibre is then taken by a discharging roller and carried forward to a carrier
roll, which latter causes the fibre to pass over a second set of saw-teeth and deliver
it to another carrier roll, from which it is transferred to the licker-in, and then
passing over a third set of saw-teeth is delivered to the main cylinder.
Under the discharging roller is a fancy-roller that serves to strip the discharging
roller, and under the latter is also arranged a series of knife edge grids that serve
to clean the wires of all refuse matter.
A shaft, having at its front end a bevel gear wheel, engages with a bevel gear
wheel on the shaft of the doffer.
On the first named shaft is also a bevel gear wheel which engages with another
bevel gear mounted on a stud which is supported in a bracket attached to the main
frame. On the inner side of the latter bevel gear wheel is a link pulley which
carries a chain that passes over a carrier pulley and around the pulleys of the
strippers, thus imparting motion to the strippers.
The last named bevel wheel is a changeable gear wheel and may be of larger or
smaller size, for the purpose of imparting a faster or slower motion to the workers
and strippers according to the different conditions of the staple of fibre.
On the opposite side of the machine is a chain which is carried on the shafts of
one stripper and one worker. Another chain also passes over the pulleys of the
workers and the carrier pulley, by means of which motion is imparted to the series
of workers.
On the shafts of one of the strippers and one of the workers are double pulleys
for carrying chains, whereby motion is imparted to another stripper and is also
communicated to the series of workers. By means of this arrangement the speed
of the workers and stripper's may be changed without interfering with the required
speed of the moving parts of the machine and vice versa.

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for " IMPROVEMENTS IN MACHINES FOR CARDING FIBROUS MATERIALS
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My invention relates to certain improvements in Carding machines in which
cotton, wool or other fibrous material may be readily carded, and the invention
consists, firstly in a means for raising the smooth roller near the rear end of the
machine away from the needle roller without removing the said smooth roller from
the machine. The invention further consists in the employment of a series of
saw-teeth bars arranged in connection with the breaker roller, the carrier roller
and the licker-in for the purpose of combing the fibres and freeing them from dirt
and other extraneous matter. And the invention further consists in a combination
and arrangement of parts hereinafter fully set forth.
Referring to the accompanying drawing:-
Fig, 1, is a side elevation of a carding machine embodying my improvements.
Fig, 2, is a longitudinal vertical section of the same.
Fig, 3, is an enlarged view in detail of the device for elevating the smooth
roller.
Fig, 4, is an enlarged view of the breaker roller and saw teeth bars.
Fig, 5, represents the saw teeth bars enlarged.
Fig, 6, shows the grid bars which are arranged under the discharging roller.
Fig 14, represents the opposite side of a corresponding portion of Fig 1.
The general construction of the frame, the cylinder and arrangement of the
workers and strippers is similar to that of well-known machines of this class.
A, is the 'lap-roller from which the lap is unrolled and delivered onto the shell-
plate B, which latter is curved upwards at its forward end, as shown. The fibre
passes from the plate B under the feed roller C, from which it is taken up by the
needle roller D, which latter combs the fibres and removes from them the heavy
dirt, seeds and sand. The smooth roller E, serves to press the fibre upon the
needles of roller D..
The roller E, is journalled in the ends of levers e, e¹, which levers are fulcrumed
on the axis of the needle roller D. The arms e, e¹, are connected together at their
outer ends by a rod or bar f, as shown in Fig 3. To the centre of the bar f, is
attached a bar or rod f¹, which extends to the rear of the machine, and is provided
at its outer end with a handle g, so that should the fibre become packed between
the feed roller C, and the needle roller D, the roller E, can be thrown away from
the feed roller D, by pulling out the rod f', thus allowing a space for the operator
to loosen the lap or remove it from the machine without stopping the machine.
F, is a breaker roller upon which the fibre passes from the needle roller D. The
breaker roller F, is caused to run at greater speed than the needle roller D, the
latter being driven by means of gearing connecting with the feed roller C, which
is slowly rotated by means of a gear engaging with a bevelled gear on a shaft U,
extending from near the front end of the machine and operated as hereinafter
stated.
The breaker roller F, passes the fibre over the saw teeth bars G, which comb it
and remove the dirt & the dirt falling down between the saw-teeth bars.
"...

page_text: The fibre is then taken by the discharging roller H, and carried forward to the
carrier roll I, which latter causes the fibre to pass over a second set of saw-teeth G¹,
and delivers it to the carrier roll J, from which it is transferred to the licker-in K,
and then passing over a third set of saw-teeth G₁ is delivered to the main
cylinder L.
Under the discharging roller H, is a fancy-roller M, that serves to strip the
roller H, and under the latter is also arranged a series of knife edge grids N, that
serve to clean the wires of all refuse matter.
U is a shaft having at its front end a bevel gear V, which engages with a bevel S',
on the shaft of the doffer S.
On the shaft U is also a bevel gear X, which engages with a bevel gear X¹,
mounted on a stud which is supported on a bracket attached to the main frame.
On the inner side of the bevel gear X¹, is a link pulley Z¹, which carries the
chain Y, that passes over carrier pulley Z and around the pulleys Q1 of the
strippers Q, as shown, thus imparting motion to the strippers.
The bevel X, is a changeable gear, and may be of larger or smaller size for the
purpose of imparting a faster or slower motion to the workers and strippers,
according to the differcnt conditions of the staple of fibre.
On the opposite side of the machine, (a portion of the same being shown in Fig 1A,
is a chain Y, which is carried on a pulley Q" of a stripper Q, and the pulley P
of a worker P. A chain Y', is also passed over the pulleys P1, P1 of the workers P,
and the carrier pulley Z", by means of which, motion is imparted to the series of
workers.
The pulley P is a double pulley for carrying the chains Y" and Y¹, whereby
the motion imparted to the strippers Q, is communicated through the pulley Qu
and chain Y to the pulley P", and thence through the chain Y₁ and pulleys P¹ to
the series of workers P. By means of this arrangement and the bevel gear
wheels X and X¹ the speed of the workers and strippers may be changed without
interfering with the required speed of the moving parts of the machine, and
vice versa.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The combination of the roller E, the lever or arms e, e¹ the bar f, and rod f¹
provided with handle g.
2. The combination of the smooth roller E, needle roller D, the breaker roller F,
and the saw teeth bars G.
3. The combination of the breaker roller F, discharging roller H, knife edge
grids N, and the fancy roller M.
4. The combination of the discharging roller H, carrier roll I, saw teeth G¹, thể
second carrier roller J, and the licker-in K, and saw teeth G".
5. The combination of the shaft U, the bevel gears V; S¹ bevel gears X, X' link
pulley Z¹ the carrier pulley Z, the chain Y, and strippers Q.
6. The combination of the chain Y", passing over a pulley P¹ on a worker P
and a pulley Q" on a stripper Q; and the chain Y¹, passing over the pulleys P¹ P¹
and the carrier roll Z, and imparting motion to the workers P, as, and for the
purpose, set forth.
