of Self-acting Mules and Twiners for Spinning and Doubling
Cotton and other Fibrous Materials.
We, HENRY BAYLEY, SON AND Company, LimitED, of Bayley Street Mills,
Stalybridge, in the County of Chester, Manufacturers and WILLIAM SWINDELLS,
of 57 Grosvenor Street Ryecroft, Ashton-under-Lyne, in the County of Lancaster,
Mechanic, do hereby declare the nature of this invention to be as follows:-
This invention relates to safety appliances for use in self-acting mules and twiners
for spinning and doubling cotton and other fibrous materials and consists in simple.
and efficient appliances by which the starting of self-acting mules and twiners after
they have been stopped for cleaning or other purposes is prevented from taking
place without the full concurrence of the persons in charge of such machines.
According to this invention we provide in a self-acting mule or twiner a catch or
detent capable of being brought into action by a weight and so arrange such catch
or detent that when the setting on or stop rod of the self-acting mule or twiner is
moved to stop the machine the said catch or detent will lock or secure the said rod
in such position and prevent it from being moved either by the person in charge of
the machine or in any other way until some person moves the said catch or detent
and so liberates the said setting on or stop rod.
The catch or detent provided according to this invention may be mounted in or
upon any suitable part of the framework of the headstock or other part of the self-
acting mule or twiner or in any suitable part secured thereto and may be arranged
and-adapted to pass into engagement with a hole or notch or stud or other suitable
device in or upon the setting on or stop rod or any suitable part secured or mounted
in or upon such setting on or stop rod or the said catch or detent may be mounted
in or upon the setting on or stop rod of the self-acting mule or twiner or in or upon
a part secured thereto and be arranged and adapted to pass into engagement with
a hole or notch or stud or other suitable device provided in or upon any suitable
part of the framework of the headstock or other suitable part of the self-acting
mule or twiner or in or upon any suitable part secured thereto. The said catch or
detent may be so arranged that when the setting on or stop rod of the self-acting
mule or twiner is moved into position to stop the machine such catch or detent shall
simply move into position to lock or secure the said setting on or stop rod in such
position or such catch or detect may be arranged so that it will be forced' in one
direction and then while the setting on or stop rod is being moved to stop the
machine be allowed to move in the contrary direction and lock or secure the setting
on or stop rod in the position into which it is then moved.
The catch or detent provided according to this invention may be formed or
provided with a head or handle or other part by which the person intending to
start the self-acting mule or twiner may move it in order to liberate the setting on
or stop rod or the said catch or detent inay be arranged so that it can only be
moved to liberate the said setting on or stop rod by means of a key or appliance
specially provided for the purpose and placed in charge of some particular person.
The appliances in which this invention consists by preventing self-acting mules
and twiners from being started without the full concurrence of the persons in

page_text: charge of them will tend to prevent accidents from being caused by the untimely
starting of self-acting mules and twiners.

Improvements in Appliances for Preventing the Accidental Starting
of Self-acting Mules and Twiners for Spinning and Doubling
Cotton and other Fibrous Materials.
We, HENRY BAYLEY, SON AND COMPANY, LIMITED of Bayley Street Mills,
Stalybridge in the County of Chester, Manufacturers and WILLIAM SWINDELLS,
of 57 Grosvenor Street, Ryecroft, Ashton-under-Lyne, in the County of Lancaster,
Mechanic, 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 safety appliances for use in self-acting mules and
twiners for spinning and doubling cotton and other fibrous materials and consists in
simple and efficient appliances by which the starting of self-acting mules and
twinere after they have been stopped for cleaning or other purposes is prevented
from taking place without the full concurrence of the persons in charge of such
machines.
According to this invention we provide in a self-acting mule or twiner a catch or
detent capable of being brought into action by a weight and so arrange such catch
or detent that when the setting on or stop rod of the self-acting mule or twiner is
moved to stop the machine the said catch or detent will lock or secure the said rod
in such position and prevent it from being moved either by the person in charge of
the machine or in any other way until some person moves the said catch or detent
and so liberates the said setting on or stop rod.
The catch or detent provided according to this invention may be mounted in or
upon any suitable part of the framework of the headstock or other part of the self-
acting mule or twiner or in any suitable part secured thereto and be arranged and
adapted to pass into engagement with a hole or rotch in the setting on or stop rod
or any suitable part secured or mounted in or upon such setting on or stop rod or
the said catch or detent may be mounted in or upon the setting on or stop rod of
the self-acting mule or twiner or in or upon a part secured thereto and be arranged
and adapted to pass into engagement with a hole or notch provided in any suitable
part of the framework of the beadstock or other suitable part of the self-acting
mule or twiner or in any suitable part secured thereto. The said catch or detent
may be so arranged that when the setting on or stop rod of the self-acting mule or
twiner is moved into position to stop the machine such catch or detent shall simply
move into position to lock or secure the said setting on or stop rod in such position
or such catch or detent may be arranged so that it will be forced in one direction
while the setting on or stop rod is being moved to stop the machine and then be
allowed to more in the contrary direction and lock or secure the setting on or stop
rod in the position into which it is then moved.
The catch or detent provided according to this invention may be formed or
provided with a head or handle or other part by which the person intending
to start the self-acting mule or twiner may move it in order to liberate the setting
on or stop rod.
A catch or detent made and employed according to this invention is illustrated
in the accompanying drawing in which Fig. 1 is a perspective view and Fig. 2 a

page_text: side clevation partly in section illustrating such catch or detent and so much of the
parts in conjunction with which it is employed as is necessary to enable this inven-
tion to be readily understood and carried into effect: Fig. 2 is drawn upon a.
somewhat smaller scale than Fig. 1.
The same letters of reference are applied to corresponding parts in both figures.
In the accompanying drawing (a) is the catch or detent made and employed
according to this invention and (b) is the setting on or stop rod of the self-acting
mule or twiner in conjunction with which the catch or detent (a) is employed.
The catch or detent (a) is formed with a part (a) adapted to pass into engagement.
at certain times as will be hereinafter described with a hole (b) formed to corre-
spond with it in the setting on or stop rod (b) and the catch or detent (a) is also
provided with a head (a) screwed upon the stem (a³) of such catch or detent (a)..
The head (a) acts as a handle to enable the catch or detent (a) to be easily
disengaged whenever required from the setting on or stop rod () and also in.
conjunction with the rest of such catch or detent (a) acts as a weight to bring such
catch or detent (a) into action. The catch or detent (a) is formed with a part (a").
fitting into a corresponding hole in a collar (c) formed upon a bracket (c) secured
by means of a set screw (d) in position upon the bracket (e) in which the setting on
or stop rod (6) is supported and guided and the collar (c) is formed with an internal
rib () which overhanging the part (a) of the catch or detent (a) prevents such
catch or detent (a) from being withdrawn from the collar (c). The hole (6') is.
formed in such position in the setting on or stop rod (b) that when such setting on
or stop rod (b) is moved to stop the self-acting mule or twiner the part (a) of the
catch or detent which will previously have been resting upon the upper surface of
the setting on or stop rod (b) will be caused by the weight of the catch or
detent (a) to move into the position in which it is indicated in Fig. 2 and enter
such hole (6') so as to lock or secure the said setting on or stop rod (b) in the
position in which it is when the part (a) of the catch or detent (a) enters the said
hole (b). When the self-acting mule or twiner is to be started the person desiring
to start such self-acting mule or twiner first raises the catch or detent (a) clear of
the hole (6) in the setting on or stop rod (b) and then moves such setting on or
stop rod (b) in the direction indicated by the arrow (A) thus moving the hole (b')
from beneath the ratch or detent (a) which resting upon the setting on or stop
rod (6) as is indicated in Fig. 1 will be held in readiness to enter the hole (6¹).
whenever the setting on or stop rod (6) may be moved in the direction opposite to
that indicated by the arrow (A) so as to stop the self-acting mule or twiner. The
weight (a) provided upon a catch or detent (a) made according to this invention.
may be made as heavy as may be considered necessary or desirable in any
particular case but if made of iron may conveniently be of the size indicated in the
accompanying drawings. By brackets (c') of different forms being employed as
may be necessary in different cases catches or detents (a) made according to this
invention may be readily applied to self-acting mules or twiners of all kinds.
Catches or detents made according to this invention are cheap, simple in construc--
tion and reliable and are not liable to breakage or derangement while in use.
The appliances in which this invention consists by preventing self-acting mules
and twiners from being started without the full concurrence of the persons in charge
of them will tend to prevent accidents from being caused by the untimely starting.
of self-acting mules and twiners.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In a self-acting mule or twiner a catch or detent (a) capable of being brought.
into action by a weight with which it is provided and so constructed arranged and
employed for the purpose and substantially in the manner herein before described
in reference to the accompanying drawings, that whenever the setting on or stop.
rod of the self-acting mule or twiner is moved into position to stop the machine the

page_text: Baid catch or detent (a) will be brought into action by the said weight and lock or
secure such setting on or stop rod in the said position until some person moves such
catch or detent (a) in order to release the said setting on or stop rod.
