"
JOHN TATTERSALL, of Preston, in the County of Lancaster, Machinist. IMPROVED
STRIPPING MOTION FOR CARDING ENGINE."
The object of this Invention is to more effectually, quick, and easy strip the flats
of carding engines. By the quickest of the present systems it takes from a quarter
to half a minute to strip one flat by a very complicated and expensive apparatus.
By my present Invention the whole is cheaply made, easily applied, not easily got
out of order, and performs its operation on each flat in a few seconds, and is con-
structed in the following manner-This motion consists of an improved slide and
levers to lift the flat from its position and carry the same away from the opening
over the cylinder, when it is stripped or cleaned by a revolving circular brush or
its equivalents, after which it is returned to its original position, the whole
operation taking only a few seconds of time and preventing any opportunity of the
dirt again falling into the working part of the card, and is as follows:- I fix
on the mangle wheel shaft a crank with connecting rod attached to the lower half
of the slide, which slide lifts the flat from its position, bringing it into connection
with a finger lever in the upper half of the slide, which lever causes the flat to
revolve in a circular groove by means of a lever fixed to the frame at one end and
working on a stud in the finger lever.
The frame for carrying the motion is similar in construction to those now in use,
and driving motion will be obtained from any convenient shaft of the engine.

STRIPPING MOTION FOR CARDING ENGINES."
"IMPROVED
My Invention consists of certain improvements in the more effectual, quick, and
easy stripping of flats in carding, whereby the flats are lifted, stripped clean
to the bottom of the wire, and replaced in a few seconds time without disturbing
the position of the wire or injuring in the slightest degree the quality of the
strippings by curling, crushing, or rolling it up.
In performing my operation of stripping I use a similar frame to those now in
use for carrying the motion. Swivelled on each side of the machine, and counter-
poised by moveable balance weights across the upper portion of the frame formed
by these side frames, I place a revolving circular brush or its equivalent, which
when the flat is brought into position against it, revolves instantly, taking cleanly
from the wire card on such flat all the cotton dust and dirt therein. The flat in
order to come in contact with such brush has to travail in a diagonal direction, so
that the stripping operation may not be performed over the space of the card
from whence the flat has just come, so that no portion of the dirt can by any
possible means fall on to the cylinder again; soon as the brush has performed
its operation on the flat such flat retires, and a comb advances, working upon a
swivel centre at each end is brought into position by a small lever; when the comb
has taken the stripped cotton from the brush it is made to retire again, but on its
passage back (which may be induced by its own loaded back, counterpoising the
front needle or comb side), the upper side of such comb is again cleared by
another swivel-ended clearer, which when the comb is taken down to clear the brush
the front edge follows by its own weight on the upper side of such comb, where it
remains until the brush is stripped, the stripping from which is on the comb and
resting against the edge of the last-mentioned clearer on comb before named. The
comb having done its work leaves the brush acting on its swivel centres at the
ends; its front edge rises up, and in doing so, the clearer edge before named being
behind the stripping, clears it cleanly from the face of the comb, carrys it in an
uninjured form out of the way, when all is ready for the next operation.
And in order that my Invention may be better understood and more readily
carried into effect, I annex herewith a Sheet of Drawings, the several Figures of
which are marked by corresponding letters of reference.
Fig. 1 is a side elevation of my improved motion; Fig. 2 is an end elevation of
the same.
Fig. 3 shows back of slide with springs attached.
Fig. 4 shows comb, levers, and stripping board.
Fig. 5 is spring catch, as shown in Figs. 1 and 2.
A is the carding cylinder shaft; B, radial arm working on cylinder pedestal ;
C, balance weight; D, driving pulley for the motion of the shaft E, which carrys
the brush and driving pinions; F, carrier wheel and pinions a; G, crown wheel;
H, half moon which is cast to wheel G, and at the back in Fig. 1, and but partialy
seen in Fig. 2; it is a spaced friction surface behind the toothed wheel Ĝ in the
space cut out of the friction surface; the teeth of the wheel G project and act upon
pinions I on its passage, and again coming in contact with a planet pinion O, on the
side of which is a cam-shaped lock piece P, which is made of such a shape as when
the spaced portion of the friction surface comes round it takes hold of such,
carrying it with the planet pinion and the lever Q having the effect of lifting
slides J, by and through connecting, rod I and crank R, the upper end of such con-
necting rod having a shoulder piece, provided to come under the end of the flat in
its upward motion, lifts it into contact with the end of lever finger K still lifting
and holding it there, while the a end of finger lever gets to the end of the cam slott

page_text: marked b. The K end of the finger lever has made a quarter of or any portion of a
circle required, carrying the flat M with it, thus bringing the under face or wire
surface of the flat in an horizontal position and within reach of the brush E¹, thus
carrying it away from over the opening on cylinder for stripping; S is the comb
swivelled at each end, and regulated in quadrant slott c; this comb advances and
retires at each action by means of levers-T and ; on the top of such comb is comb
clearer V; this is fulcrumed at each end in suitable bearings; it has a front lip a
bearing on the heel of the comb when such comb is down, taking the strippings
from the brush, but as the edge of the comb rises the edge of the comb clearer rises
gradualy from the heel to the points of such comb, carrying the strippings clearly
off such comb to a receptacle of any convenient form, from whence it is taken away.
Soon as the flat is stripped, and while the comb. clearing is taking place by the
continuance of the motion of the crown wheel G, the flat instantly resumes its
position on the cylinder ready for next forward movement for the next flat.
The action on and of the brush is effected as follows:-At the back of the frame B,
immediately in front of slides J, is a diagonal slott lever 1 at each end of machine,
the top end of which forms or is connected with the bearings carrying the ends
of brush spindle 2. On the side of slide J is a stud 3, fixed, which works in such
slott, which on its rising to its extream upper action has brought the stripping
brush into contact with the flat, likewise brought up and turned with its face to
such brush by the other side action of or from the upper slide J on the finger lever,
with its stud a working in slott b.
The action on comb and clearer is obtained from lower slide J, and diagonal lever
inside frame sides and worked by a stud and slott.
Fig. 3 shows the slides J, end of connecting rod I, with the spring w, which being
attached to the upper slide J at t; when this is brought down to its carding
position, the beviled end at x comes in contact with a projection on the slide
frame B, thus throwing it off from lower slide J at y, and allowing the lower slide J
to be drawn down so as to leave the space m, to allow the next flat to pass freely
between which the next operation lifts.
Fig. 4 is a larger side view of bracket W, showing end of brush, comb, and
clearer.
Fig. 5, front and side views of spring u.
I have now described the several parts of my Invention and their individual uses.
The action is as follows:-Motion is given to pulley D, to shaft E, driving
pinion F, carrier pinion a, crown wheel G, acting on pinion I', lifting thereby the
lower slide J by crank and connecting rod R and I till lower slide J comes to upper
slide J, when the flat is firmly held and carried upward, gradually assuming a
horizontal position, yet in a diagonal direction, until it comes in contact with a
brush which instantly cleans it, to the bottom of the wire. The comb as instantly
combs cleanly the brush, when on its retiring it is again cleared and the strippings
entirely removed by the clearer, and all in a few seconds.
Having described my Invention and the way it is worked, I wish it to be
distinctly understood that I do not confine myself to the precise details I have had
occasion to describe and refer to, as many variations may be made in detail without
deviating from the principle or main features, but what I claim as secured to me
