Improvements in Self-acting Mules.
I, WILLIAM HENRY KERSHAW, of Clay Street, Tuel Lane, Sowerby Bridge,
Yorkshire, Spinning Master, do hereby declare the nature of this invention to be
as follows:
My invention has reference to the "snarling motion" of self-acting mules, the
object of which is to prevent the snarling of the yarn.
In carrying out my invention I make use of the ordinary catch or roller clutch
box containing a notched disc working between lugs on the loose part of the catch
box, all of which are well-known and in general use.
A
The object of my invention is to turn back or reverse the loose half of the clutch
after it has done its work so as to be ready for the next operation, and this propose
to do by placing around the loose half of the clutch box a spring clip, the tension
of which around the clutch box may be regulated by an adjusting nut and screw, or
the tension of the clip may be sufficiently strong without the adjusting screw.
finger or arm projects from the spring clip, to which I attach a cord with a weight
at one end, so that when the clutches are liberated, the weighted cord acting upon
the finger of the spring clip moves the loose half of the clutch box partially around,
putting it into a position to be ready for the next operation. In order to determine
how much the spring clip shall operate the catch box, one or two studs are made
to project from the headstock of the mule, against which the finger of the spring
clip acts. One of the studs is made to be adjustable so as to allow of more or less
movement of the spring clip according to circumstances.
Instead of the spring clip being made to move by a cord and weight a spiral
spring may be employed.
By the adoption of the spring clip and weight for purposes herein described, the
parts working the catch box are reduced in number and simplified; the cost thereof
is also lessened.

COMPLETE SPECIFICATION.
Improvements in Self-acting Mules.
I, WILLIAM HENRY KERSHAW, of Clay Street, Tuel Lane, Sowerby Bridge,
Yorkshire, Spinning Master, 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:-
My invention has reference to the snarling motion of self acting mules, the object
of which is to prevent the snarling of the yarn.
In carrying out my invention I make use of the ordinary catch or roller clutch
box on the front spindle shaft, such catch box containing a notched disc working
between lugs on the loose part of the clutch box, all of which are well known and
in general use.
The object of my invention is to turn back or reverse the loose half of the clutch
after it has done its work, so as to be ready for the next operation, and this I
propose to do by placing around the loose half of the clutch box a spring clip, the
tension of which around the clutch box may be regulated by a spiral spring, or the
tension of the clip may be sufficiently strong without the spiral spring. A finger
or arm projects from the spring clip, and a cord with a weight at one end, or a dead
[Price 6d.]

page_text: weight, is also employed, so that when the clutches are liberated the weight over-
comes the spring clip, and moves the loose half of the clutch box partially around,
putting it into position to be ready for the next operation. In order to determine
how much the spring clip shall operate the clutch box, one or two studs are made
to project from a bracket attached to the headstock of the mule, against which the
finger of the spring clip acts. One of the studs is made to be adjustable' so
as to allow of more or less movement of the spring clip according to circumstances.
In order that my invention may be more fully understood, I will now make
reference to the accompanying sheet of drawings illustrative thereof, wherein Fig. 1
is front elevation of such parts of the mechanism in connection with the snarling
motion as are necessary to illustrate my invention, and Fig. 2 is end view of the
same. A represents the front spindle shaft on which is fixed the ordinary clutch
box mechanism, not shewn in the drawings. B represents the loose half or sliding
part of the clutch box, one part of which is grooved to receive my improved spring
clip C, kept at a suitable tension by the spiral spring D, such spring clip also being
provided with a finger E, and a cord and weight F. To the headstock of the mule
I attach a bracket G provided with a slot H, in which is a fixed stud I and an
adjustable stud J, between which studs the finger E is allowed to move, which
studs also determine the extent of movement allowed to the spring clip and finger.
The extent of movement, however, can be made more or less by the adjustable
stud J, therefore when in the ordinary working of the machine the clutch B carries
the finger against the fixed stud I and the clutches have become liberated, the
weight will draw the loose half of the clutch box Baround or move it on its shaft
until the finger E reaches the stud J, whereby the clutch box will be in a position
for the next operation required of it, which is common and well known in this class
of mule. In Figs. 3 and 4 I have shewn a slight modification or adaptation of the
spring clip C, where it will be seen that instead of having a cord and weight F, the
spring clip is provided with a dead weight K, whilst the finger E of the spring clip
moves between the fixed point I and the adjustable stud J, which is the extent of the
motion allowed to the finger and the spring clip, and instead of the adjustable stud J
being operated by a thumbscrew L as shewn in Figs. 1 and 2, the said adjustable
stud Jis attached to a nut M, on the horizontal screw N, which can be operated in
either direction by the handle O.
By the adoption of the spring clip and weight, for the purposes herein described,
the parts working the catch box are reduced in number and simplified, whilst the
cost thereof is also lessened.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
Firstly. In the snarling motion of mules, the use of a spring clip on the loose
clutch box, the tension of such clip being governed by spiral spring in manner
substantially as described and shewn in Figs. 1 and 2.
Secondly. In the snarling motion of mules, the use of a spring clip on the loose
clutch box, operated when released by a cord and weight, substantially as described
and shewn in the drawings.
Thirdly. In the snarling motion of mules, the use of a spring clip on the roller
clutch box, operated when released by a dead weight, substantially as described and
shewn in Figs. 3 and 4.
