Improvements in and Connected with the Sliver Can Supports in
Textile Machinery.
I ELIJAH ASHWORTH of the firm of Ashworth Brothers of the. Moss Brook Works,
Collyhurst, Manchester, in the County of Lancaster, Engineers, do hereby declare the
nature of this Invention to be as follows :-
My Invention relates primarily to the revolving table which sustains the sliver can
whilst it is being filled with sliver and is particularly adapted for application to
carding engines although I do not confine myself to such application. In ordinary
practice the attendant removes the can when it is sufficiently filled according to his
judgment but in cases wherein his attention is not directed to the can at the proper
time there is a liability for the sliver to be packed too forcibly into the can or for the
sliver to escape to the outside and in any such case there is a tendency for the sliver
to be injured. To remedy this defect is the object of my invention. I sustain the
can upon a table or support by means of a spring or weight or of springs or weights
which is or are designed to permit the said table to yield in a downward direction
when the can is filled to a suitable degree the downward movement of the table being
employed to operate upon parts which warn the attendant that the can should be
removed. The details of the apparatus may be greatly varied. In one arrangement
the can rests upon a support which is provided with a central spindle which is fitted
to slide in a bearing formed in the revolving carrier means being provided to cause
the said support to revolve with the said carrier. The lower end of the said spindle
bears upon a footstep or part which is sustained by means of a spring or of a lever
which is acted upon by a spring or is otherwise loaded. The resistance of the spring
or the weight upon the lever is calculated to sustain the can and the sliver therein
until the weight of the added sliver and the downward pressure due to the com-
pression of the same are sufficient to overcome the resistance of the spring or load
and the can support moves downward. From the said support I transmit motion
through levers and rods or shafts or suitable parts to the signal apparatus, as for
example the aforesaid loaded lever may be connected with a semaphore arm which
may be raised when the can is sufficiently filled or nearly so or the movement of an
arm finger index or part may furnish the desired intimation. The action of the
sustaining spring or load or of the sustaining parts may be adapted to cause the
yielding to take place slowly or quickly. In the former case the slow movement of
the semaphore or other part would indicate to the attendant that the can required his
immediate or early attention. The downward movement of the can support may be
used to set in motion parts which will furnish a sound signal such signal being used
either in conjunction with the semaphore or visible signal or in lieu thereof as for
example the aforesaid loaded lever may be connected with a lever or finger which is
part of a bell signal apparatus. When the support yields as aforesaid the said lever
is brought into position to be acted upon by an excentric or wiper upon the shaft
which drives the revolving table the said wiper being similar to a ratchet wheel or
being of other suitable formation. If preferred the movement of the support may act
upon parts which complete an electric current and thereby cause a bell signal to
sound. By means of my invention the cans may be filled much more regularily than
is the case in ordinary practice as it will be apparent that the apparatus may be
adapted to approximately weigh the quantity of sliver which is to constitute a charge
for the can.
If preferred the revolving table which directly receives motion may be
mounted to yield at the required times.

Improvements in and Connected with the Sliver Can. Supports in
Textile Machinery..
I ELIJAH ASHWORTH. of the firm of Ashworth. Brothers of the Moss Brook Works,
Collyhurst, Manchester, in the County of Lancaster, Engineers, 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 :-
My Invention relates primarily to the revolving table which sustains the sliver can
whilst it is being filled with sliver and is particularly adapted for application to
carding engines although I do not confine myself to such application. In ordinary
practice the attendant removes the can when it is sufficiently filled according to his
judgment but in cases wherein his attention is not directed to the can at the proper
time there is a liability for the sliver to be packed too forcibly into the can or for the
sliver to escape to the outside and in any such case there is a tendency for the sliver
to be injured. To remedy this defect is the object of my invention. I sustain the
can upon a table or support by means of a spring or weight or of springs or weights
which is or are designed to permit the said table to yield in a downward direction
when the can is filled to a suitable degree the downward movement of the table being
employed to operate upon parts which warn the attendant that the can should be
removed.
In order that my Invention may be clearly understood I will describe the same
more fully with reference to the accompanying drawings.
In the said drawings Figs. 1 and 2 represent front and side elevations partly in
section of a sliver can and coiler constructed in accordance with my invention and
Fig. 3 is a plan of the parts which would be below the revolving platform which
sustains the can. In the said Figs. a is the sliver can b is the revolving platform
which carries the said can and c is the ordinary coiler head carried by the hollow
column d. The can is sustained by a yielding table e which is supported by means
of three spiral springs f. f. The said table is fixed upon one end of a spindle g which
is fitted to slide up and down in a hole which is bored in the centre of the platform b
the said spindle keeping the table in position and guiding it to move vertically in a
straight line when yielding to the weight or downward pressure of the sliver can and
its contents or to the upward pressure of the springs. The said springs are calculated
to sustain the weight of the table e the can a and of the quantity of sliver required to
fill the can to a suitable extent. When the can is full the weight of the contained
sliver and the increased pressure arising from the increased compression of the added
sliver will overcome the resistance of the springs and the table e will move downward.
In the space below the said table two levers h and i are mounted upon fulcra at h¹
and ¹. One end of the lever h bears upward against the lower end of the spindle g
the other end resting upon the short arm of the lever i. The longer arm of the lever i
is connected by means of a rod k with a semaphore arm which is mounted upon a
fulcrum at the arrangement being such as that the short downward movement of
the table e is multiplied by the levers so that the rod k acting on the short arm of the
lever which constitutes the semaphore I raises the longer arm from its lower position.
such as is indicated by the dotted lines into the position indicated by the full lines.
and thus gives warning to the attendant. It will be seen that this upward movement
would take place slowly so that the attendant would receive early warning if he
noticed the commencement of the slow upward movement of the semaphore and he
would know that the can would require his immediate or early attention. If preferred
however the parts might be so arranged as that the semaphore would go up quickly
and also if preferred such movement might be attended with a noise. I may arrange
for the attraction of the attention of the attendant by means of a sound signal alone
that is to say without the use of the semaphore or in conjunction with such use
as for example the movement of the rod k might by simple means bring into

page_text: action parts which would cause a bell to be struck the motion being derived from the
vertical revolving shaft within the column d. For this purpose a wiper or ratchet
wheel upon the said vertical shaft might act at the required times upon the lever or
part carrying the bell hammer or an arrangement similar to a watchman's rattle
might be used. I may employ an electric hell or sounder the lowering of the table e
being arranged to complete the circuit and thereby to bring the bell apparatus into
action. In such a case the circuit might include a sounding apparatus situated in
the managers office or in any other office or place as desired and by well known or
simple means the particular carding engine might be indicated by number or other
suitable indication. The arrangement of parts illustrated in the drawings may be
greatly varied without departing from the nature and intent of my invention. The
number or forms of the springs may be varied or if preferred weights might be used
as for example the lever h might be made stronger and be loaded to sustain the
required weight of can and sliver. In place of the semaphore arm any suitable form
of arm index or finger may be used. By means of my invention the cans may be
filled much more regularily than is the case in ordinary practice as it will be apparent
that the apparatus may be adapted to approximately weigh the quantity of sliver
which is to constitute a charge for the can. If preferred the revolving table which
directly receives motion may be mounted to yield at the required times the additional
table e being dispensed with in such a case.
my said
Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed I declare that
what I claim is :-
(1) The combination of parts substantially as and for the purpose set forth with
reference to the accompanying drawings.
(2) The table e mounted and arranged to yield downward when the sliver can has
become filled to the desired extent.
(3) Sustaining the can which receives the sliver from the carding engine upon
a table which is supported by a spring or by springs or by a weight or by weights
in such a manner as that when the can is sufficiently full the table will yield and
will act upon parts which display or give use to a visible or an audible signal or to
both substantially as and for the purpose set forth and indicated.
(4) Sustaining a sliver can upon a table which can yield when the can is suitably
full and which by so yielding acts upon parts which give warning so as to direct
attention to the can substantially as set forth.
(5) Sustaining a sliver can upon a table which can yield when the can is suitably
full and which by so yielding completes an electric circuit whereby apparatus is acted
upon and notifies the fact that the can is full.
