Improvements in Carding Machinery.
We IRA FRANKLIN LAWRY, Mechanic, and Joux TEMPEST MEATS, Superin-
tendent, both of Taunton in the State of Massachusetts one of the United States of
America 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 in carding machines has for its object to provide the same with
stop motion mechanism whereby the doffing and feeding mechanism may be
automatically stopped whenever the lap runs out.
With stopping mechanism for the doffer and feeding mechanism and main
cylinder, we have also combined two sets of feeding mechanism whereby two laps
may be simultaneously fed to the main cylinder at different points to thereby better
and more evenly supply the main cylinder with fibrous material to be carded, such
feeding not only resulting in increasing the product of the card but also improving
the quality of the carded material, and this is accompanied with less wear on the
delicate card teeth.
This provision for stopping the action of the feeding mechanism which supplies
the laps to the cylinder, and for stopping the doffer, is of especial importance when
two, or it may be more, laps are being fed to one and the same cylinder, for unless
the said parts be stopped as soon as one lap runs out or off the roll the film taken off
the cylinder by the doffer would vary in weight and thickness, thus making it
impossible to produce uniform yarn.
Our invention therefore consists in a carding machine containing the following
instrumentalities, viz. :-a card cylinder feeding mechanism therefor; and a
doffer; and their actuating mechanism; of stop motion devices intermediate the
said feeding mechanism and the said doffer actuating mechanism, whereby on the
running out of the lap the feeding mechanism and the doffer are automatically
stopped, substantially as will be described.
Also in a carding machine containing the following instrumentalities, viz. :—a
card cylinder; two sets of feeding mechanism therefor; and a doffer; and their
actuating mechanisni; of stop motion devices intermediate the said feeding
mechanisins and the said doffer actuating mechanism, whereby on the running out
of a lap the feeding mechanisms and the doffer are automatically stopped,
substantially as will be described.
Fig. 1, in side elevation represents a carding machine embodying my invention,
the top flats not being shewn, as they may be of any usual construction and be
manipulated in any usual way, part of the toothed gear F and part of the frame-
work being broken out to show parts behind them.
Fig. 2 is a partial plan and sectional view in detail chiefly to show the stop
motion devices intermediate the feeding mechanism and the doffer actuating
mechanism, part of the friction pulley hub shown separately in Fig. 5ª being broken
out to show parts below it.

We have omitted the teeth from the different cylinders to simplify the drawing.
Referring to the drawing, A represents a carding cylinder; and B, a doffer of

page_text: As herein represented, the feeding mechanism consists of a feed roll C shewn by
dotted lines Figs. 1 and 6, and enlarged in Fig. 24, the journals of which are
mounted in suitable bearings, the said feed roll acting upon a single thickness
of the lap lying upon a shell or plate c', as it is called, of usual.construction.
The lap D wound upon any metal lap rod t rests upon a lap roll E' of usual
construction, except that the longitudinal grooves ex therein are made deeper than
heretofore in order that the said lap rod may enter one of the said grooves when
the lap runs out or becomes exhausted, and in doing so set into operation the-stop
motion, to be described.
Co-operating with the feed roll C and located between it and the main cylinder
is a licker-in of usual construction, it having upon one end, see Fig. 6, a
pulley R.
As herein represented, the feed roll C has fast upon one end of it a toothed
gear which is engaged by an intermediate gear G, in turn engaged by a gear d
mounted upon a stud 2 secured to the frame-work, the said gear having attached
to it a worm toothed gear which is engaged by a worm d upon a rotating shaft
having at its opposite end a beveled gear de which is engaged by a beveled gear 3
at the interior of the part K of a friction pulley mounted upon a stud K³ projected
from one side of the frame-work.
Co-operating with this friction pulley K2 is a pulley part K* which receives about
it the belt K' extended around a pulley M fast on one end of the cylinder shaft; so
that the said cylinder when rotated in usual manner will through the belt rotate
the pulley part K, and when the part K is in contact with the part K2 will rotate
the feed roll to feed the lap to the licker-in, the latter taking the lap from the feed
roll and giving it up to the carding cylinder-in usual manner.
Instead of the particular pulley K, we may employ any other usual or suitable
friction pulley or toothed clutch pulley, and instead of the worm gear and worin
pinion, we may use any other usual gearing.
The intermediate & referred to, engages a toothed gear F1 fast on the shaft of
the second feed roll C, it being just like the feed roll C before described.
Co-operating with this second feed roll marked Cis a licker in the feed roll C
acting upon the material delivered from a lap, not shewn, but wound upon arods,
the lap-resting upon-a-lap-roll-E-
To avoid confusion in the description immediately above, the licker-in, co-operating
with the second feed roll has been marked it being just the same tin construction
as the licker-in l.
-From-the-foregoing-description-it-will-be-readily-understood-that-the-two sets
we
of feeding mechanism may be actuated in unison, and instead of the particular
feeding mechanism, each set of which is shown as containing a roll and a plate,
may employ any other usual or suitable feeding mechanism commonly employed in
connection with carding machines.
are
The pulleys R and Ron the shafts respectively of the licker-in rolls
driven by a belt R2 which is actuated by a pulley S fast upon the main cylinder
shaft, the said belt passing over idler pulleys Y and Z and also over a pulley.V
mounted upon a suitable stud of the frame-work, the pulley V having alongside of
it a pulley which drives the belt V extended over the usual shaft Vs for actuating
the comb V which takes the film from the doffer B, the said comb in practice being
of any usual construction.
The shaft P of the doffer B has suitable bearings in the frame-work and said
shaft is provided with a gear O which is engaged by a pinion connected to and so
as to be rotated with the part 2 of the driving pulley.
Co-operating with the feeding mechanism containing the roll C is a lever band
co-operating with the feeding mechanism containing the roll Cis a lever b¹; each
of the said levels being suitably, pivoted upon stands 62, 6³.
The inner ends of these levers b, b', are jointed-together by a rod m; so that when
one or the other lap rod comes upon one of the other of the said levers, both of them
will be moved to start the operation of the stopping mechanism to be described, of

page_text: which stopping mechanism they both form a part when two sets of feeding mechanism
are used.
Upon the frame side are suitable bearings 2 which receive a rock-shaft / having
at one end a collar provided with a lug or projection ³, the said rock-shaft at its
other end having a collar provided with a lug or projection m³, and near its end
having also connected to it a collar m³ having a pin m which engages the lower
end of a lever n pivoted at n' upon a stand n².
The upper end of the lever n has ears to enter an annular groove in the hub of
the pulley part K
One of the stands 2, namely, that one at the left in Fig. 1, has a stud 4 which
constitutes the fulcrum for the shipper lever f having an arm
which is extended
The shipper leverf has a projection which is engaged by a catch or projection
forming part of the lever, the said catch engaging the said projection when the
machine is running and the laps are being properly fed to the main cylinder, but
as soon as a lap rod strikes the outer or short arm of either lever b, 6, the lever b
is lifted to remove its catch from the projection, letting the spring y connected
to the shipper leverf move the said lever so that its arm acting on the pro-
jection will turn the rock shaft and the lever and cause the latter to disengage.
the pulley parts so that the part K' is left at rest and consequently the feeding
mechanism and the doffer actuating mechanism and doffer are immediately arrested
in their motion.
so as to come within the range of movement of the projection k².
If it is desired to start the machine from the doffer end thereof, the operator will
push back the catch pivoted upon a part of the frame-work and disengage it from
the lever r acted upon by the spring causing said spring to turn the rock-shaft
having a projecting forked arm which engages the projection m², the projection k²
at such time acting on the arm on the shipper lever, throwing its upper end over
to the left viewing Fig. 1. putting its projection f in position to engage the latch ƒ³
of the lever f.
Instead of the particular intermediate devices between the doffer actuating
gear and the feeding mechanism, we may use any other usual or equivalent means
to stop the rotation of the said gear co-incident with the stopping of the feeding
mechanism.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
1. In a carding machine, the following instrumentalities, viz. :-a card cylinder;
feeding mechanism therefor; and a doffer; and their actuating mechanism; of stop
motion devices intermediate the said feeding mechanism and the said doffer actuating
mechanism, whereby on the running out of the lap the feeding mechanism and the
doffer are automatically stopped, substantially as described.
