Twisting, or Doubling, and other Descriptions of Machines.
We, HERBERT WHITWAM of the Firm of B. and J. Whitwam and Sons Limited,
of Stanley Mills, Golcar near Huddersfield, Yorkshire Woollen Manufacturers and
HERBERT TAYLOR of the same place Spinner do hereby declare the nature of this
invention to be as follows:-
This invention has reference to the method of and means for stopping spinning,
twisting or doubling machines, or other descriptions of machines where applicable, the
object of such invention being to prevent accidents; and to immediately stop the
machine when breakage of any of the parts occurs, at whatever part of the machine
the attendant may be standing.
In order to carry out our invention when applied for instance-to a mule, we
employ a band or string running the length of the machine and placed in a suitable
position on the front of the carriage, such string being connected to and supporting a
piece of metal placed near the "headstock" of the mule. A slot or opening is made
in the lower end of this piece of metal through which passes a wire or cord running
alongside the headstock and connected to a catch attached to the framing at the front
end of the headstock" and holding a suitably shaped lever, which is connected by
cord or wire to the strap fork or guide which moves the strap from the fast to the
loose pulley or vice versa, for the purpose of stopping or starting the machine.
If an attendant at one end of the machine or in any other position in front of the
machine should get caught by any moving part and cannot release himself, he takes
hold of the band running in front of the machine and pulls it so as to draw up the
piece of metal consequently drawing up the wire or cord which passes through the slot
formed therein, the result being that the catch is operated and releases the lever,
which, by means of a strong spiral spring and the cord or wire connected thereto and
to the strap guide, causes such strap guide to move the driving strap from the fast to
the loose pulley and thereby siop the machine, allowing the attendant to release
177

page_text: himself, or wait until assistance arrives without sustaining injury he would otherwise
receive if the machine had not been brought to a standstill. Another advantage
resulting from the employment of the mechanism above described, is, that, if any of
the ropes for operating the carriage, or other working parts of the machine should
happen to break as is often the case, the attendant is not required to go to the head-
stock before the machine can be stopped, but can immediately stop the machine at
whatever distance he may be from the headstock so long as he is near or within the
mule gate.
It will be understood that the method of applying the above apparatus to other
descriptions of machines will vary according to the various constructions and
arrangements of such machines.

I, HERBERT WHITWAм, of the Firm of B. & J. Whitwam and Sons Limited,
Stanley Mills, Golcar, near Huddersfield, Yorkshire, Woollen Manufacturers, and
HERBERT TAYLOR of the same place, Spinner, 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 has reference to the method of and means for stopping spinning,
twisting, or doubling machines, or other descriptions of machines where applicable,
the object of such invention being to prevent accidents and to immediately stop the
machine when breakage of any of the parts occurs, at whatever part of the machine
the attendant may be standing.
In order that our invention may be better understood, we will now proceed to
describe the same more fully, and for that purpose make reference to the accompanying
sheet of drawings illustrative thereof. The apparatus shewn in the drawings is
assumed as being applied to a self acting mule, but it may with equal advantage be
applied to other kinds of machinery. A is a bell crank lever hinged upon the
fulcrum B on the framework of the machine. The upper arm of the bell crank lever
is connected by a cord C to the strap fork employed for moving the strap from the
fast to the loose pulley, whilst the shorter or lower end of the bell crank lever rests
upon the upper end of another lever D hinged at E. The lower end of lever D is
passed over a bar or rod F connected by links a to a stud b projecting from the
bracket C₁ the said rod F extending the full length of the headstock of the mule. G is
a bar or plate placed vertically having a hole at its lower end through which the
horizontal rod F passes whilst the upper end of the said bar G is connected to two
cords H and I placed full length of the mule. It will therefore be seen that if the
operative is at one end of the mule, or in any other position in front thereof, and
should be caught by any moving part of the machine, he can immediately take hold
of one of the cords H and I, and pull it in such a manner as to raise the plate G
upwards, in doing which the bar F will be raised, working upon its fulcrum b, the
effect of which will be that the upper end of bell crank lever D will be removed from
underneath the lower end of bell crank lever A, a strong spiral spring J being
employed to ensure that the bell crank lever A shall be lowered as shewn in dotted
lines, whereby the cord C will operate the strap fork in such a manner as to remove
the driving strap from the fast to the loose pulley so as to immediately stop the
rotation of the machine, allowing the operative to release himself or wait until
assistance arrives, without sustaining the injury he would otherwise have received if
the machine had not been brought to a standstill. Another advantage resulting from
the employment of the mechanisin above described is that if any of the ropes for
operating the mule carriage or other working part of the machine should happen to

page_text: break, as is sometimes the case, the operative is not required to go to the headstock
before the machine may be stopped, as is now the case, but he can immediately stop
the machine at whatever distance he may be from the headstock, so long as he is near
or within the gate of the mule.
Although we have described this invention as being applicable to a mule, it must
be understood that it may with equal advantage be applied to other descriptions of
long machines or frames.
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:-
The means or method substantially as herein shewn and described for stopping the
rotation of machinery.
