PROVISIONAL SPECIFICATION.
Improvements in or connected with Self-aoting Mules for Spinning
Yarn.
I, JOHN STARK, of Primrose Bank, Ashton New Road, Droylsden, in the County
of Lancaster, Overlooker, and JOHN CLEGG, of Stoneleigh Street Oldham in the
County aforesaid, Foreman do hereby declare the nature of the said invention to be
as follows:-
The object of this invention is to provide a nosing motion for selfacting mules
which will be automatic in its action and gradually alter its position at each
successive movement or draw of the carriage so as to put the required amount of
tension on the quadrant chain.
On the end of the quadrant stock we pivot a lever preferably curved or bent
which can be moved to and fro on its pivot and to the head-stock or framing
behind the quadrant we pivot on a fixed stud an arm or lever reaching down towards
the floor. These two pivoted levers are connected together by a connecting rod
with a slot at one end which slides on a pin. The end of this connecting rod is
preferably pivoted on a pin projecting from the side of the lever on the quadrant-
stock and the slot in the other end engages with a pin projecting from the side of
the lever depending from the head-stock. A third pivoted lever is pivoted to a
stud carried by a bracket on the headstock foot one end of which is forked or
otherwise formed to engage with a nut on the shaper screw, by which it is moved
in one direction or the other as the shaper screw is turned. The free end of this
lever engages with the lower end of the depending lever thus gradually altering
the position of the latter and thereby of the lever which acts upon the quadrant
chain.
Instead of employing the depending pivoted lever the lever which receives
movement from the shaper screw may be connected direct to the lever on the
quadrant stock by a rod or chain. The chain will attach at one end to the first
lever and passing over one or two guide pulleys will at the other end attach to the
other lever.
When the appliance is to be placed outside the quadrant we prefer to use the
depending lever and connecting rod but when inside the quadrant I use the chain
the guide pulleys being affixed to the headstock foot.

COMPLETE SPECIFICATION.
Improvements in or connected with Self-acting Mules for Spinning
Yarn.
We, JOHN STARK, of Primrose Bank, Ashton New Road, Droylsden, in the
County of Lancaster, Overlooker, and JOHN CLEGG, of Stoneleigh Street, Oldham,
in the County aforesaid, Foreman, 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 is designed with the object of providing an improved automatic
nosing motion for self acting mules, by which the required movement at each
successive draw of the carriage-to give the desired amount of tension to the
quadrant chain is imparted by the shaper screw,

The quadrant A, quadrant stock B, the shaper screw C, the winding chain D,
the winding drum D, the headstock and other parts of the mule are constructed
in the usual way, and we have omitted from the drawings all parts except such as
are connected with the present invention.
On the end of the quadrant stock B is pivoted a bracket E preferably curved
or bent in front elevation with a L shaped end c which as the head of the quadrant
stock is depressed, bears against or upon the winding or quadrant chain D. At
the end of the headstock framing, to a bracket attached to the foot of the framing
or to the floor. We pivot a horizontal lever F, one end of which is attached or
connected to a nut G on the shaper screw C which moves gradually forward at
each movement of the screw. The end of the horizontal lever F is preferably
forked to embrace the screw and abut against the nut G. On the end of the
headstock framing, behind the quadrant A, on a fixed stud a, we pivot a depending
arm or lever H reaching down to the floor. The lower end of the depending
lever H engages with, or comes in contact with the free end of the horizontal
lever F, and as the lever F is moved by the shaper screw C, the motion is
transmitted to the depending lever H. The depending lever H and the bracket E
are connected together by a connecting rod or link I, which at one end is formed
with a slot i to fit into or engage with a stud projecting from the side of the
depending lever H, and at the other end fits onto a stud e¹ at the end of the pivoted
lever E. The position of the stud h may be adjusted in a slot h¹ of the lever H,
and as the quadrant A is raised, the rod or link I slides back over the stud h.
This arrangement shows the connection made outside the quadrant which is what
we at present prefer.
When it is desired to place the connecting mechanism inside the quadrant A we
dispense with the depending lever H and connecting rod or link I, and connect the
horizontal lever F with the bracket E of the quadrant stock by means of a chain
or rope K passing over the guide pulleys k affixed to the headstock foot the chain
being attached to the stud el at one end and to the stud h' at the other end. The
action of the other parts are similar to that already described as the horizontal
lever Fis moved by the shaper screw C the pivoted bracket E is drawn down upon
the winding chain D.
It will also be obvious that instead of dispensing with the depending lever H,
the link I only may be removed, and the lever H connected to the bracket E by a
chain.
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 :-
(1) In a self-acting mule, a nosing motion having a bracket or lever E pivoted
to the quadrant stock, which bears upon the winding chain, and a horizontal
lever F attached to or actuated by the shaper screw C in combination with the
depending lever H and link I or the chain K by which they are connected together
substantially as described.
(2) A nosing motion for self-acting mules, actuated direct from the shaper

and shown with reference either to Figs. 1 and 2, or Figs. 3 and 4.
