PROVISIONAL SPECIFICATION.
An Improved Clearer for the Drawing and Calendering Rollers of
Machines used in Preparing and Spinning Cotton and other
Fibrous Substances.
I JOHN MULLIN of Shrigley Road Bollington in the County of Chester,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved clearer to be applied to the drawing rollers
of machines used for drawing slubbing, intermediate, roving and spinning frames
and also to the calender rollers of "coilers" used in carding engines and drawing
frames and other preparing and spinning machinery where such rollers are
employed, the objects of the invention being to keep the surface of the rollers clean
and thus to prevent the rollers from "licking" or "lapping."
The invention consists principally of a metal plate covered with what is known
as "clearer-cloth " and pressed against the surface of the roller or rollers by means
of a spring, or springs, so that as the roller revolves the surface is constantly wiped
or cleared.
In the case of a "coiler" the clearer plate is made with two slots and two holes
a slight distance from the ends of the slots. Two hooks and two springs are
attached to the hinged top plate of the "coiler" the hooks corresponding with the'
slots in the coiler plate and the two springs are just within the books. and press
against the back of the coiler-plate so as to press its covered surface against the
top of the calender rollers.
The coiler plate is attached by passing the slots over the fixed hooks until the
plate has passed the points of the hooks, then sliding the plate along until the
points of the hooks come opposite to the two holes and then releasing the pressure
so that the points of the hook pass into the holes and thus secure the plate.
They can be readily removed by reversing this operation that is, by pressing the
clearer plate against the springs until the holes are clear of the points of the
hooks, and then sliding the plate along until the slots can pass over the hooks. A
hole is made in the centre of the clearer plate to receive the small'end of the
trumpet guide.
I may remark that if preferred the slots and holes can be made in the top plate of
the "coiler" and the hooks fixed to the clearer-plate.
The method of applying these removable spring clearer plates to the drawing or
calendering rollers of other kinds of frames will be readily understood by any
competent mechanic.

An Improved Clearer for the Drawing and Calendering Rollers of
Machines used in Preparing and Spinning Cotton and other
Fibrous Substances.
I JOHN MULLIN of Shrigley Road Bollington in the County of Chester,
Gentleman, 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 improved clearer to be applied to the drawing rollers
of machines used for drawing slubbing, intermediate, roving and spinning frames,
and also to the calender-rollers of "coilers" used in carding engines and drawing
"frames, the objects of the invention being to keep the surface of the rollers clean
and thus to prevent the rollers from "licking" or "lapping."
The nature of my said invention and the manner in which the same is be
performed or carried into practical effect will be readily understood on reference
to the sheet of illustrative drawings hereunto annexed and the following explanation
thereof.
The drawings represent (for the sake of illustration or example) the application
of my invention to the calendering rollers of a "coiler" Fig. 1 being a section of so
much of the upper portion thereof as is necessary to illustrate the application of
my invention thereto, and Fig. 2 an underneath view of my improved clearer,
Fig. 2 is a plan of part of one of my clearer plates detached, Figs. 3 and 4 are
similar views of a slight modification thereof hereinafter more particularly
referred to.
a (Fig. 1) is part of the upper portion of the "coiler" and 6 is part of the hinged
top plate or cover.
as
The invention consists principally of a metal plate e covered with what is known
"clearer-cloth" and pressed against the surface of the roller or rollers d_by
means of a spring, or two springs e as shown, so that as the rollers d revolve their
surface is constantly wiped or cleared.
In the case of a "coiler" the clearer plate c is made with two slots fand two
holes (see Fig. 2^) a slight distance from the ends of the slots. Two hooks g
and two springs e are attached to the hinged top plate 6 of the "coiler" the hooks
corresponding with the slots f in the clearer plate c and the two springs are just
within the hooks g and press against the back of the clearer-plate c so as to press
its covered surface against the top of the calender rollers d.
The clearer-plate c is attached by passing the slots fover the fixed hooks 9, then
sliding the plate c along in the direction of the arrow Fig. 2 until the points of the
hooks g come opposite to the two holes f* as shewn and then releasing the pressure
so that the points of the hooks g pass into the holes f* and thus secure the plate
at the same time that the latter can readily yield to the pressure of the springs.
The clearer-plates c can easily be removed by reversing this operation, that is by
pressing the "clearer-plates c against the springs h until the holes f* are clear of
the points of the hooks g, and then sliding the plate e along in the reverse direction
until the slots f* can pass over the hooks, as shown by the dotted lines at Fig. 1.
A hole i is made in the centre of the clearer-plate c to receive the small end of the
trumpet guide k.
"
I may here remark that, if preferred, the slots f and holes f* may be made in
the hinged top plate 6 of the "coiler," and the hooks g fixed to the "clearer-
plate" c.
'
In some cases I propose to modify this arrangement as shown at Figs. 3 and 4 by
making the hooks g as shown at Fig. 3 and making notches (instead of slots and
holes) in the edge of the clearer-plate c. When putting on or taking off the plate c
both hooks are turned in the saine direction as shown by the dotted lines at the

page_text: left hand of Fig. 3, and all that is necessary to secure the same is to turn one of the
hooks half round.
In this case the hole i needs only to be sufficiently large to allow the sliver to
pass through the same.
The method of applying these removable spring clearer-plates to the drawing or
calendering rollers of other kinds of frames used in preparing and spinning cotton
and other fibrous substances will be readily understood by any competent mechanic
and is so obvious as to require no further illustration.
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 construction and application to the drawing rollers of slubbing, intermediate,
roving and spinning frames, and also to the calender rollers of "coilers" used in
carding engines and drawing frames of detachable spring "clearer-plates" substan-
tially as hereinbefore described and illustrated by the drawings annexed.
