COMPLETE SPECIFICATION.
Improvements in Self-acting Mules.
We, WILLIAM BRYDEN of Jowetts Terrace, Overlooker, and HARRY STANSFIELD
of Sugdens Buildings Foreman Spinner, both of High Street Morley near Leeds in
the County of York, 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:-
Our invention has reference to self-acting mules, and is for the purpose of simpli-
fying and more readily reversing the motion of the spindles for producing different
twists of the warp and weft threads. The spindles are driven by cords or bands
from one cylinder or "tin-roller" extending the full length of the machine, and
hitherto for the purpose of changing the twist of the thread from right to left hand or
vica-versa, each cord or band had to be changed from a cross to the straight, or vica-
versa on purpose to change the direction of the spindles and alter the twist, such
operation taking up a great amount of time, and causing considerable trouble. Now
in our improvements we under all circumstances allow the driving cords or bands to
remain the same, and for the purpose of altering the twist or changing the direction
of the spindles we reverse the driving cylinder or "tin-roller," producing thereby
the desired effect in a very simple and ready manner.

In the accompanying drawings Fig. 1 is a back elevation. Fig. 2 an end elevation
and Fig. 3 a plan looking at the top, in which A shews part of framework of
machine, and B the shaft carrying the cylinder or
"
tin-roller C. When the
cylinder or roller C is required to rotate in one direction, we give motion thereto
from driving shaft D through wheels E F. G. H and J, the last named wheel J being
fixed on the same shaft B as the cylinder or "tin-roller," and when required to
be moved in the opposite direction we take off the intermediate wheel F which leaves
the remaining wheels inoperative, and slide the first named wheel E into gear direct
with the cylinder or roller C, motion being imparted through studs K or clutches.
For convenience we divide the cylinder or "tin-roller" in the above arrangement, as
shewn in the drawing, to make room for the wheel J. Suitable bearings L are
employed and attached to the framework, thus supporting the cylinder or " tin-roller
and wheels as shewn.
"
It is to be understood that we do not limit ourselves to the precise details of the
mode of construction, or arrangement of wheels for reversing the action of the cylinder
or "tin-roller," as it is evident that these may be varied or modified without departing
from the nature of our said invention.
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 employed for reversing the action of the cylinder or tin-roller and
consequently the motion of the spindles, without the necessity of removing or altering
the position of the driving cords or bands, substantially as and for purposes herein
set forth.
