IMPROVEMENTS IN APPARATUS FOR AUTOMATICALLY STOPPING MACHINES EMPLOYED FOR COMBING AND PREPARING FIBROUS SUBSTANCES
Year: 1884

page_text: I, JOHN WILLIAM GAUNT of Summerfield, Calverley Lane, Bramley, in the
County of York, Spinner and Manufacturer do hereby declare the nature of my
invention for IMPROVEMENTS IN APPARATUS FOR AUTOMATICALLY STOPPING
MACHINES EMPLOYED FOR COMBING AND PREPARING FIBROUS SUBSTANCES to be
as follows:-
•
This invention relates to certain improvements in machines employed in the
manipulation of fibrous substances and is applicable to the combing, carding and
other machines used in the preparation of the material for the spinning frame, and
has for its object the automatic stoppage of the machine to which the apparatus is
applied whenever the sliver or cord of fibre is broken or reduced in thickness which
I accomplish in the following manner:-
The sliver or cord of fibre is made to pass over one end of a lever, to the other
end of which I attach a bar and a sliding weight adjusted so that the pressure of
the fibre on the lever is of such an extent, that the weight and bar are raised, that
the latter is clear of a revolving disc arranged somewhat as follows:
To a vertical revolving spindle I secure a disc to which is attached a catch held
against the circumference of the same by a spring-above this disc-is another,
that is free on the said spindle and revolves with the first named disc by frictional
contact, and to the upper dise is secured a cam that projects beyond the circum-
ference. In case the 'sliver or cord of fibre passing over the lever is broken or
reduced in thickness that the tension or weight of the same allows the weighted
end of the lever to descend until the bar attached thereto rests upon the upper
disc, the rotation of the same will stop, when a portion of the cain comes in contact
with the bar, the bottom disc continuing to revolve until the catch secured thereto
comes against the cam which will cause the catch to pass over the exterior surface
of the cam and dislodge a lock catch, thereby liberating a lever to which is attached
a spring by which the lever is actuated, and the belt shifting bar connected
therewith moved that the belt is moved from the fast to the loose pulley thus
stopping the machine,

Machines Employed for Combing and Preparing Fibrous
Substances
I, JOHN WILLIAM GAUNT of Summerfield, Calverley Lane, Bramley in the
County of York, Spinner, do hereby declare the nature of my invention for
IMPROVEMENTS IN APPARATUS FOR AUTOMATICALLY STOPPING MACHINES EMPLOYED
FOR COMBING AND PREPARING FIBROUS SUBSTANCES, 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 certain improvements in machines employed in the
manipulation of fibrous substances, and is applicable to the combing, carding, and
other machines used in the preparation of the material for the spinning machine;
and has for its object, the automatic stoppage of the machine to which the apparatus
is applied, whenever the sliver or cord of fibre is broken or reduced in thickness;
and consists in conducting the sliver or cord of fibre so as to pass over one end of
a lever, to the other end of which I attach a bar and sliding weight, the latter
being adjusted so that the pressure of the fibre passing over the lever is of such
an extent, that the weight and bar are raised to such a height, that the end is clear
of a revolving disc arranged somewhat as follows:
To a vertical revolving spindle I secure a disc to which is mounted a catch arm
held in the requisite position by a spring; and above this on the same spindle, is
another disc that revolves with the first named by frictional contact, and to which
is secured a cam that projects beyond the circumference. In case the sliver or cord
of fibre passing over the lever is broken, or the pressure reduced so as to allow the
bar at the opposite end of lever to descend until it rests upon and stops the upper
disc; then the catch arm on revolving disc, will come in contact with the cam, and
on the end passing over the exterior surface, will dislodge a catch hook; thereby
liberating a lever, to which is attached a spring by which the lever is actuated and
the belt shifting bar connected therewith moved, shifting the belt from the fast to
-the loose pulley, thereby stopping the machine.
I will now proceed to describe my invention more in detail, reference being made
to the accompanying drawings, in which Fig. 1 represents a sectional elevation of
such portions of a "Noble's" combing machine as are required to explain my
invention. Fig. 2 is a sectional plan of the same through lines a. b. and Fig. 3 is
a detached détail of my improvement.
The fibre is fed to the comb circles in the ordinary manner, but the sliver from
each side of the large circle is conducted and combined with the sliver from the
respective small circle comb A, and before entering the ordinary revolving funnel B,
the two combined slivers pass over the ends C of the respective levers C¹, which
are mounted in joints D. Each lever is provided with a weight W, and adjusted
so that the pressure of the two combined slivers on the ends C of the respective
levers, will be such as to raise the bars E clear of the disc F, which is free on the
vertical spindle G, and rests upon the fixed disc H.

page_text: The spindle G is driven from the ordinary gearing under the bed plate; and
near the top of the spindle, is secured disc H shewn in detail by Fig. 4, and which
is provided with a catch arm J mounted on a stud and kept. in the position as
shewn in the said detail against pin K by spring S. Above disc H on the said
spindle is another disc F, (shewn by detail Fig. 5) which is free, of smaller
diameter, and to which is secured cam L projecting beyond the circumference, also
plate L' both of which are hereinafter described.
In case any of the slivers break, or either of the two combined slivers become so
reduced in thickness that the pressure of the same on either of the levers C¹ is not
sufficient to keep the end of the respective bar E clear of the disc, it will descend
until it rests upon the face of the upper disc F, which will continue to revolve until
the plate L¹ comes in contact therewith and stops the same; the lower disc H still
revolving, when the raised portion J¹ at end of catch arm J will come in contact
with the cam L, the spring S will then yield and allow the end J¹ to pass over the
exterior face of the said cam, by which means the end J' is brought into contact
with the end of catch arm M, moving it in the direction of the arrow (see Fig. 6)
thereby liberating the lock catch N, and lever P, to which spring S₁ is attached;
and being in tension, will cause the lever P, to move the belt fork R from the fast
pulley T to the loose pulley T, thus stopping the machine before any so-called lap
can be formed on the drawing off rollers or leathers which would do damage to the
pins of the comb circle.
The above describes my invention as applied to a "Noble's" combing machine,
but it is also applicable to carding and other machines in which a sliver is formed,
and may be applied to the machines in such a position so as to obtain the weight
of the sliver on the end of lever in order to keep the bar clear of the upper disc F,
which when the sliver is reduced in thickness, or broken, will descend, stop the
upper disc, and operate upon the catch arm M, thereby stopping the machine
through levers arranged in a manner suitable to the class of machine to which my
improvement is applied.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim, is
The arrangement and combination of an apparatus by which machines are
stopped automatically, when the sliver is broken or reduced in thickness, the
whole being arranged and operated upon substantially in the manner described in
reference to the accompanying drawings.
The combination of the two discs F and H with the arm M all constructed and
arranged substantially in the manner shewn and for the purpose described.
