(5
The object of cur Invention is to strip the card cylinders doffers and rollers of
carding engines by self-acting mechanisin and in a more perfect manner than this
operation has been hitherto accomplished by hand.
Our Invention consists in portable mechanism, which is intented to be carried
from one engine to another and readily placed upon fixings on the framing by
which the apparatus is adjusted to the card cylinder to be operated upon.
The mechanism is operated by a belt from a pulley on the axis of the card
cylinder or by other arrangements.
The mechanism consists of a shaft to pass across the engine and this shaft has
bearings in a bracket or frame at each end, which is placed upon the side frames of
the engine.
Each end frame has a stud for a spur wheel driven from a pinion on the cross
shaft, and this spur wheel has a disc attached to it which forms a cam and carries a
crank nin on its face.

page_text: The end frame also carries a stud for a lever to oscillate upon and this lever
has a cam groove or slot in it and it is or may be oscillated by the rotating cain.
In the cam groove bowls work which are secured on studs in the end of a bar
extending across the engine and having the stripper card attached to its under
face, and this cross bar is jointed by a connecting rod with the crank pin on the
disc.
Similar mechanism is used on both sides so that when the cross shaft is rotated
by the driving belt both ends of the cross bar carrying the stripper card are
reciprocated to produce a combing action on the card teeth of the cylinder to be
operated upon and the cam slotted lever lifts the stripper card (by the action of
the rotary cam) as it passes back over the card teeth and depresses it so that its
teeth enter between those of the card cylinder as it passes forward; and after it
has left the card cylinder, the cam slot in the lever, comes the stripper card to lift
and pass over a card fixed on a bar passing across between the end frames, the
teeth of which strip the fibre from the stripper card, and the fibre thus taken is
discharged from the teeth of the fixed card into any suitable receiver.
Another modification consists in securing the bar for the stripper card on the
end of an arm or lever which has its fulcrum on the end of a bell-crank lever,
having its on a stud in the end frame, the other arm of the bell crank lever
carrying a bowl to work against a rotary cam on a shaft across the engine, in
the face of which there is a crank pin which gives motion by a rod to the arm or
lever carrying the stripper card, and thus gives a to and fro movement between
the card cylinder and the fixard card for stripping the stripper card.
The mechanism described is the same for both sides of the engine.
In both arrangements the card cylinder is geared with the stripper mechanism,
so that the cylinder will move a certain distance after each stroke of the stripper
card.
The mechanism described may be modified and arranged in various ways so as
to produce the action required, without departing from our Invention.

"IMPROVEMENTS IN MECHANISM OR APPARATUS FOR STRIPPING CYLINDERS,
DOFFERS AND ROLLERS OF CARDING ENGINES FOR CARDING COTTON, WOOL,
AND OTHER FIBROUS MATERIALS."
The object of our Invention is to strip the card cylinders, doffors and rollers of
carding engines by selfacting mechanism and in a more perfect manner than this
operation has been hitherto accomplished by hand.
Our Invention consists in portable mechanism, which is intended to be carried
from one engine to another and readily placed upon fixings on the framing
by which the apparatus is adjusted to the card cylinder or card surface to bo
operated upon.
The mechanism is actuated by a belt or band from a pulley on the axis of the
card cylinder or by other arrangements.
The mechanism consists of a shaft to pass across the engine and this shaft has
bearings in a bracket or frame at each end, which is placed upon the side frames
of the engine. Each end frame has a stud for a spur wheel driven from a pinion
on the cross shaft, and this spur wheel has a disc attached to it which forms a cam
and carries a crank pin on its face or the crank pin is in the spur wheel and the
cam is separate from it.
The end frame also carries a stud for a lever to oscillate upon and this lever has
a cam groove or slot in it and it is or may be oscillated by the rotating cam or the
lever is oscillated by another lever actuated by the cam.
In the cam groove, bowls work which are secured on studs in the end of a bar
extending across the engine and having the stripper card attached to its under
face, and this cross bar is jointed by a connecting rod with the crank pin on the
disc or spur wheel.
Similar mechanism is used on both sides so that when the cross shaft is rotated
by the driving belt both ends of the cross bar carrying the stripper card are
reciprocated to produce a combing action on the card teeth of the cylinder or card
surface to be opereated upon and the cam slotted lever lifts the stripper card (by
the action of the rotary cam) as it passes back over the card teeth and depresses it
so that its teeth enter between those of the card cylinder as it passes forward, and
after it has left the card cylinder or surface the cam slot in the lever causes the
stripper card to lift and pass over and through a card fixed on a bar passing across
between the end frames, the teeth of which strip the fibre from the stripper card,
and the fibre thus taken is discharged from the teeth of the fixed card into or on
to any suitable receiver. Another modification consists in securing the bar for the
stripper card on the end of an arm or lever which has its fulcrum on the end of a
bell crank or other lever, having its fulcrum on a stud in the end frame, the other
arm of the bell-crank or other lever carrying a bowl to work against a rotary cam
on a shaft across the engine in the face of which there is a crank pin, or there is
an excentric on the shaft which gives motion by a rod to the arm or lever carrying
the stripper card, and thus imparts to it a to and fro movement between the card
cylinder or surface and the fixed card for stripping the stripper card.―The
mechanism described is the same for both sides of the engine.

page_text: In both arrangements the card cylinder is or may be geared with the stripper
mechanism, so that the cylinder or card surface will move a certain distance after
each stroke of the stripper card, or the cylinder or card surface is moved by hand
while being stripped.
The mechanism described may be modified and arranged in various ways so as
to produce the action required without departing from our Invention.
Fig. 1 is a sectional cnd elevation and Fig. 2a side elevation at one end
illustrating one modification of our Invention.
When our Invention is applied for stripping card cylinders or other card surfaces
such as "revolving flats," the apparatus is arranged and fixed so that the surface of
the stripper card will act upon and work in or about a line that will be parallel to
or at a tangent to the circumference of the cylinder dofler or card surface to be
operated upon.
When used on card cylinders it is placed and arranged on that part of the
cylinder nearest to, and above the doffer of the engine, by preference and in this
position, sockets a are secured on the bends or framing of the engine on each
side for the stems to fit in which form the bearings to carry the entire
apparatus.
At the bottom of each socket a there is an adjusting screw a' the end of which
comes against the end of the stem b, and it is by these screws a¹ (one in
each socket) that the stripper card c is adjusted to the card surface to be operated
upon.
is a shaft in bearings on the stem parts band at one end there is a pulley ¹
for an endless band, which is driven from the loose pulley or any convenient
rotating part the cylinder or card surface to be operated upon being moved
slowly by hand under the stripping card by the attendants-or this movement
may be given to the card cylinder by an excentric on the shaft & working a rod
with a pawl tooth on its end which will work on ratchet teeth in a wheel on the
axis of the card cylinder, or ratchet teeth formed on the side of the fast pulley on
the axis of the cylinder for the driving belt or any other suitable gearing is or may
be used if desired.
On the shaft dat each side there is a spur pinion that drives a spur wheel e
which rotates freely on a stud secured in the part b.
The stud also forms the fulcrum of a plate f having a cam slot fin it to
attached for
which plate one end of the bar g' is secured which has the card
stripping the stripper card c that is attached to a bar c¹ having a small bracket c²
at each end which carries the pivots of two rollers that work in the cam slot f¹ in
the plate -The spur wheel e has a crank pin e' secured in it to which one end of
a rod e² is connected the other end of which is jointed to a pin in a part 3 secured
in the stripper card bar c'.
There is a stud 2 secured in the part b and one end of it passes through a slot
in the plate f which permits of movement in this plate, on its fulcrum b, and the
end of this stud forms the fulcrum of a lever one end of which is jointed by a
screw pin with the end of the plate fat f, the other end of this lever h comes
under a cam attached to and rotating with the boss of the spur wheel e.
When the spur wheel rotates the crank pins e' move the stripper bar e to and
fro, the ends being guided in the cam slots and the plates fare moved up and
down by the cams 'acting upon the levers h so that when the strpper card c
moves forward it is lifted over and above the card surface to be stripped, and is
lowered into it when about to begin making its back movement, and it carries the
material stripped through the card g and leaves it there, when it makes its forward
movement and as it accumulates it is pushed off the card g by each back move-
ment and is received on to the wire supports g² until it can be taken away by hand
at intervals.
The mechanism at one side is a duplicate of that at the other, but one side is
right and the other left.
Our selfacting stripping apparatus is intented to be used in place and in the

page_text: position of the rotary cylindrical brush hereto used in many cases, and it acts more
effectually and gets more to the bottom of the card than a brush does without
throwing off the fibres to float about in an objectionable manner in the atmosphere
of the room where the machine is working and it is portable and can be
conveniently carried from one engine and readily applied to another engine.

cam is (which may be a double acting or box can if required) secured on the
shaft d. Duplicate apparatus is used on each side so that when the shaft d is
rotated the stripper card c is, by the action of the excentrics c¹ and cams i³, moved
to and fro and up and down as described in reference to Figs. 1 and 2.
In place of excentrics e' the shaft d may be made cranked if desired.
