PROVISIONAL SPECIFICATION.
An Improvement applicable to the Coilers of Carding Engines.
I CHARLES ETCHELLS of 122 Wharf Street Dukinfield in the County of
Chester, Card Stripper and Grinder do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improvement applicable to that part of a carding
engine known as the "coiler" which is employed for coiling the sliver as it is
delivered from the "doffer" into a compact form in a revolving can, the object of
the said invention being to stop the delivery of the sliver by the doffer as soon
as the required amount of sliver has been coiled into the can.
For this purpose instead of mounting the bottom of the can upon a rigidly fixed
revolving plate as usual we interpose a spring box, the spring of which is sufficiently
strong to hold up the weight of the can and its coil of sliver, but as soon as the can
becomes filled to such an extent that the sliver commences to exert an upward
pressure against the underside of the coiler plate, it forces the can downwards.
Beneath the bottom of the can I place a lever one end of which is provided with
a set screw and the other end is connected to the lever which supports the spur
pinion which drives the doffer wheel, in such a way that when the coiler can is
forced down by the pressure of the sliver it causes the last named lever to draw the
spur pinion out of gear with the doffer wheel, and thus stops the delivery of the
sliver, so that all waste by the sliver running over the cans is thereby prevented.
The amount of pressure which is allowed to accumulate inside the can before the
doffer is stopped may be regulated by means of the set screw before mentioned.
Dated this 8th day of June 1891.

COMPLETE SPECIFICATION.
An Improvement applicable to the Coilers of Carding Engines.
1 CHARLES ETCHELLS of 62 Victoria Street Ashton under Lyne in the County
of Lancaster, late of 122 Wharf Street Dukinfield in the County of Chester, Card
Stripper and Grinder, 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 an improvement applicable to that part of a carding
engine known as the "coiler' which is employed for coiling the sliver as it is
delivered from the "doffer" into a compact form in a revolving can, the object of
the said invention being to stop the delivery of the sliver by the " doffer as soon
as the required amount of sliver has been coiled into the can.
::
My invention will be readily understood from the following description on
reference to the sheet of drawings hereunto annexed on which Fig. I is a sectional
elevation of our improvement applied to a coiler can Fig. 2 is a plan view of the
saine. Fig. 3 is a side elevation of part of a carding engine showing how our
invention may be applied thereto. Fig. 4 is a front elevation with the coiler can
removed.
a is the coiler-can, b (Fig. 3) is the lever which carries the pinion l' which
actuates the doffer wheel c.
Instead of mounting the bottom of the can a upon a rigidly fixed revolving plate

page_text: as usual we interpose a spring box a' see Fig. 1 the spring a² of which is sufficiently
strong to hold up the weight of the can a and its coil of sliver, but as soon as the
can becomes filled to such an extent that the sliver commences to exert an upward
pressure against the underside of the coiler plate a*, it forces the can a
downwards.
Beneath the bottom of the can I place a lever done end of which is provided
with a set screw and the other end is connected to the lever which supports
the spur pinion which drives the doffer wheel c in such a way that when the
coiler can is forced down by the pressure of the sliver it causes the last named
lever to fall and draw the spur pinion out of gear with the doffer wheel c and
thus stops the delivery of the sliver, so that all waste by the sliver running over
the cans is thereby prevented.
This is preferably effected as follows:-
The plate a³ upon which the coiler can a rests in the usual manner is carried by
means of its central boss a' by the spring a², the pressure of which can be regulated
by the set screw a³.
The amount of pressure which is allowed to accumulate inside the can a before
the doffer is stopped may be regulated by the before named set-screw d' on the end
of the lever d.
The other end of this lever d is connected by a link e to a lever pivotted to
and reaching across the front of the carding engine, see Figs. 3 and 4, and connected
at its other end by the links gl and g², and lever g, to the catch on the lever h
which supports the lever by the link in the usual manner.
As soon as the set screw di is depressed by the pressure of the sliver in the coiler
can the other end of the lever d'is raised and (by means of the link e, lever
links g, and g, and lever ) raises the catch from its fixture h³ on the framing of
the carding engine, and releases the lever which then allows the lever b to fall
and draw the pinion out of gear with the doffer wheel c.
I would remark in conclusion that the means of connecting the lever d with the
mechanism which releases the lever will of course vary according to the make
and arrangement of the carding engine to which my invention is to be applied.
The application of the spring support to the coiler can may also be modified
without departing from the principle of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is
The combination with the coiler plate and coiler can of a carding engine of a
spring supporting the said can and a lever so connected to the lever which carries
the pinion for driving the doffer wheel as to stop the motion of the doffer as soon
as the required amount of sliver has been coiled into the can.
