Improvements in Flat Carding Engines for Oarding Fibrous
Materials.
We EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY, of
Globe Works, Castleton, near Manchester, in the County of Lancaster, Machinists
dó hereby declare the nature of this invention to be as follows :—
This invention relates to improvements in the mechanism employed for driving
the flats of flat carding engines, also to improvements in the method of and means
employed for operating the stripper comb, and to a device for cleaning and removing
dust from the circular plate or disc which carries the Bats. The object of the
invention is to ensure efficient lubrication of the worms and worm wheels of the
flat driving shaft, and to allow of the parts being readily disconnected, so that
the flat can be turned by hand. The stripper comb is operated so that in its
downward stroke it is near to the points of the teeth of the flats, and on its up
stroke it is carried away and clear of same.
In carrying out the first part of our invention, we form a hollow box for
carrying the worms and wheels for giving motion to the driving or star wheel
shaft. The bottom of this hollow box serves as a receptacle for oil, and ensures
the parts being efficiently lubricated. On the shaft for supporting the lower worm
and wheel, we form a key or float, and a keyway is formed in the worm and wheel
for its reception. This shaft is arranged to slide in the worm and wheel, and is
provided with two grooves cut in its circumference. A stop piece is provided to
At these grooves.
When the stop piece is in one groove, the worm and wheel are
connected by the key or float, but when the stop piece is put into the other groove,
the wheel is disconnected from the lower worm wheel, and can be driven or moved
by the worm by hand. We hinge a cover over the worms, worm wheels, and
hollow box, so as to prevent loose fibres and dirt accumulating thereon or
therein.
In carrying out the second part of our invention, we fix eccentrics to each end
of the brush roller shaft. Each of these eccentrics carries one end of a connecting
rod, the other end of the rod being supported by the lever fixed to the rocking
shaft that usually gives motion to the comb. By fixing the comb a short distance
from the lower ends of the eccentric rods the comb blade partakes of a portion of
the motion of both the eccentrics and the levers from the rocking shaft, and thus
causes the comb to pass nearer the flat on its downward stroke than it does on its
upward stroke, and so enables the comb to be set closer withont liability of damage
being done to the wire on the flats.
To prevent dust or dirt collecting or remaining on the periphery of the circular
plate or disc for carrying the flats when being cleaned by the stripper comb, we
employ a weighted lever with an inclined projection, which rests on the periphery
of the disc or plate, and acts as a scraper on same.

Materials.
We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY, of
Globe Works, Castleton, near Manchester, in the County of Lancastor, Machinists,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:—
This invention relates to improvements in the mechanism employed for driving
the flats of Ant carding engines and appliances connected with such mechanism;
also to improvements in the method of and means employed for operating the
stripper comb, and to a device for cleaning and removing dust from the circular
plate or disc which carries the flats. The object of the invention is to ensure
efficient lubrication of the worms and worin wheels of the flat driving shaft, to
protect the same from dust and dirt, and to allow of the parts being readily
disconnected, so that the flat can be turned by hand. The stripper comb is
operated so that in its downward stroke it is near to the points of the teeth of the
flats, and on its up stroke, it is carried away and clear of same, thereby being less
liable to damage the card teeth.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which :-
Fig. 1 is a side elevation of part of a flat carding engine, shewing the position
thercon occupied by the said improvements.
Fig. 2 is an end elevation of part of a flat carding engine, with the improvements
applied thereto.
Fig. 3 is a side elevation of Fig. 2.
Fig. 4 is a similar view to Fig. 3, but shewing the comb as operated by
mechanism preferably adapted when the cleaning brush is driven slowly, as is
sometimes the case.
In carrying out the first part of our invention, we form a hollow box 1 for
carrying the worms 2, 3, and wheels 4, 5 for giving motion to the driving or star
wheel shaft 6. The bottom of this hollow box 1 serves as a receptacle for oil,
and ensures the parts being efficiently lubricated. On the shaft 7 for supporting
the lower worm 2 and wheel 4, we form a key or float 8, and a key way 9 is formeil
in the worm 2 and wheel 4 for its reception. This shaft is arranged to slide in
the worm 2 and wheel 4, and is provided with two grooves 10, 11 cut in its
circumference. A stop piece or stud 12 is provided to fit these grooves. When
the stop piece is in one groove 10, the worm 2 and wheel 4 are connected by
the key or float 8, but when shaft 7 is drawn outwards, and the stop piece 12 is
put into the other groove 11, the wheel 4 is disconnected from the lower worm 2,
and the flats can be driven by the shaft 7 and worm 2 by hand, and without
operating or driving the wheel 4 and worm 3. We hinge a cover 13 over the
worme, worm wheels, and hollow box, so as to prevent loose fibres and dirt
accumulating thereon or therein.
In carrying out the second part of our invention, we fix eccentrics 14, one at
each end of the brush roller shaft 15. Each of these eccentrics carries one end of
a connecting rod 16, the other end 17 of the rod being supported by the lever 18,
fixed to the rocking shaft. 19, that usually gives motion to the comb 20. By
fixing the comb 20 a short distance from the lower ends of the eccentric rods 16,
the comb blade partakes of a portion of the motion of both the eccentrics, and
the levers from the rocking shaft, and thus causes the comb to pass nearer the flat

page_text: on its downward stroke than it does on its upward stroke, and so enables the
comb to be set closer to the wire without liability of damage being doue to the
wire on the flats.
When a slow motion is given to the brush roller shaft 15 (see Fig. 4) and
brush, the latter is driven by means of a large wheel on the brush shaft 15 driven
by a small pinion, and an open driving rope 15 is employed. In this case the
eccentrics 14 for working the comb 20 are fixed on the quick running shaft 16^,.
which carries the pinion for driving the brush shaft 15, so that the requisite quick
motion for the comb is obtained. The eccentrics 14 being driven in a reverse
direction, it is necessary that the centros 17 or points where the connecting
rods 16 are jointed to the rods 18, should be above the comb 20, instead of below
it, so that the requisite motion of the combs 20 is obtained.
The links 18 may be pivoted on the star wheel shaft 6 as shewn, instead of
being connected with the rocking shaft as shewn in Fig. 3.
To prevent dust or dirt collecting or remaining on the periphery of the circular
plate or disc for carrying the flats when being cleaned by the stripper comb, we
employ a weighted lever 20, with an inclined projection 21, which rests on the
periphery of the disc or plato 22, and acts as a scraper on same.
Having now particularly described and ascertained the nature of our sail inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
(1.) The hollow box, so constructed as to form a carrier and an enclosing and a
lubricating chamber for the gear, substantially as shewn by the drawings annexed,.
and berein fully described.
(2.) The improved gear, together with carrying and enclosing box, forming a
lubricator, all in combination, and as described herein, and illustrated by the
accompanying drawings.
(3.) Stripping combs, so mounted and operated as to be in contact with the wire
or cards on the downward or effective stroke, and removed clear away from the
wire on the return or non-effective stroke by means heroin fully described, and
illustrated by drawings annexed.
