PROVISIONAL SPECIFICATION.
Improvements in or relating to Coiler Cans of Drawing Frames
employed in the Preparation of Cotton and other Fibrous
Substances.
We, THOMAS HITON of Ash Bank, Sharples, Astley-Bridge near Bolton,
Manager, and WILLIAM SHAW of 40 Wilton Street, Astley-Bridge near Bolton,
Carder, both in the County of Lancaster, do hereby declare the nature of our said
invention to be as follows:-
This invention refers to improvements in or relating to coiler cans of drawing
frames employed in the preparation of cotton and other fibrous substances and is
designed to stop the coiler can immediately it is full, thereby limiting the contents
to a stated quantity by which the sliver will be kept cleaner and more uniform than
hitherto. This we carry into effect by mounting on the coiler top a bracket or
fixing in which are disposed compound levers on suitable pivots or centres. The
upper lever is provided with a catch which operates in conjunction with a
projection on the bracket or fixing to prevent the former being raised too high, thus
ensuring of the sliding stop rod being arrested to stop the machine when a can is
full of sliver. The upper lever is raised by a bottom lever provided with a vertical
rod or pin, the latter being raised by the lifting of the coiler plate and wheel inside
the coiler top by the amount of sliver or upward pressure of same. The bottom
end of the vertical rod or pin is rounded to prevent the same damaging or engaging
with the cogs or teeth of the wheel attached to the coiler.

Improvements in or relating to Coiler Cans of Drawing Frames
employed in the Preparation of Cotton and other Fibrous
Substances.
We THOMAS HITON of Ash Bank, Sharples, Astley-Bridge, near Bolton, in
the County of Lancaster, Manager, and WILLIAM SHAW of 40 Wilton Street,
Astley-Bridge, near Bolton, Carder, 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 and accompanying drawings:
This invention refers to improvements in or relating to coiler cans of drawing
frames employed in the preparation of cotton and other fibrous substances, and is
designed to stop the coiler can as soon as it is full, thereby limiting the contents to
a stated quantity so that the sliver is kept cleaner and more uniform than
hitherto.

page_text: The following description of our invention will be more clearly understood by a
reference to the accompanying sheet of illustrative drawings.
Fig. 1 is a view of the upper portion of a coiler can, part of the coiler top being
shown in section.
Figs. 2 and 3 are enlarged vertical sectional views at the line A, B Fig. 4, of the
pivotted compound stop levers or tumblers which constitute the gist of my invention
and which are carried on the coiler top.
Fig. 4 is a plan view of the compound stop levers and their casing.
There is practically no change in the construction and arrangement of the coiler
can and coiling mechanism except that provision is made to allow the coiler plate
and spur wheel a to be capable of being slightly lifted by the rising sliver when the
can b is full.
The spur wheel on the coiler plate a gears with and is driven by another toothed
wheel c, or from any other suitable source. The sliver after leaving the usual
trumpet passage, passes down through the curved branch a' on the revolving coiler
plate and is coiled in the case b. It will be noted in Fig. 1 that the coiler top e
carries a bracket f within which are disposed the aforesaid pivotted compound stop
levers or tumblers.
This bracket with its contained levers 9 and is illustrated more clearly in the
enlarged views Figs. 2 to 4. The upper stop lever g is loosely pivotted at g' and
has a tail g² to prevent the lever from being raised above the height shown for
example in Fig. 3.
The tail g comes against a part 1 of the bracket f and is thereby arrested.
When not in operation the lever g lies about level with the top of the bracket fas
shown in Fig. 2. Beneath the lever g is a second lever pivotted loosely at h¹ to
the bracket f. The nose 2 of the lever supports the lever g, and the lever h is in
its turn supported by the loosely pivotted pin i the rounded end of which rests on
the rim of the wheel on the coiler plate a as seen at Fig. 1 but so as to be clear of
the teeth. The appearance of the rounded end of the pin i from a direction at
right angles to the views in Figs. 2 and 3 is indicated in Fig. 2. It will be seen
that owing to the compound arrangement of the levers 9 and a very slight lift of
the pin suffices to raise the flat end of the stop lever g into the position shown at
Fig. 3.
The usual sliding stop rod is indicated by k in the drawings. This rod recipro-
cates to and fro just above the bracket f. While the coiler cau is being filled it is
allowed to do so without interruption. But as soon as the coiled sliver rises above
the top of the can and touches the coiler plate a, the latter is raised slightly and
this pushes up the pin i whereby the lever is canted from the position shown in
Fig. 2 to the position shown in Fig. 3 and so as to present a stop to the next
forward stroke of the stop rod k. The stop rod being thus arrested stops the
machine in the ordinary way and the filled sliver can is then removed and replaced
by an empty can.
l
The bracket with its compound levers can easily be attached to existing coiler
tops by means of bolts or screws passing through holes in the snugs on the sides
of the bracket as shown in Fig. 4.
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. The improved stop action for application to coiler cans substantially as
described and as illustrated.
2. A stop action for application to coiler cans and consisting of the pivotted
compound stop levers or tumblers g h pivotted within the bracket for other suitable
housing and operated by the pin i from the coiler plate and wheel a or their
equivalent, so as to arrest the movements of the stop rod and so stop the apparatus
when the coiler can is full, substantially as described and as shown in the
drawings.

page_text: 3. The general arrangement, construction and combination of the coiler cau
coiling mechanism with the pivotted compound stop levers or tumblers and
dependent parts, for the purposes and substantially as hereinbefore described and
shown.
