Improvements applicable to the "Nosing. Motion" of Self-acting
Mules.
I, JONATHAN HARGREAVES, of 41, Upper George Street, Tyldesley, near, Man-
chester, in the County of Lancaster, Mill Manager, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the part of the quadrant winding motion of self-
acting mules known as the "nosing motion "the object of which is to cause the
speed of revolution of the spindles to increase as the nose of the cop is being formed
in a ratio exactly corresponding with the gradually decreasing diameter or taper of
the spindle towards the point, so as to cause the spindle always to wind-on the
yarn at an even speed corresponding with that of the going-in of the carriage.
For this purpose, instead of casting the toothed quadrant and the quadrant arm
in one piece, or making them in two pieces rigidly bolted together as usually
practiced, I make them in two separate parts both turning on the same centre or
fulcrum but mounted in such a manner that they can move independently of
each other.
The quadrant is acted upon by the toothed pinion in the usual manner and its
end is carried past the lever and is then bent at a right angle or provided with a
facing which as the quadrant is moved back holds the lever into the usual position,
and a coiled or other spring is connected from one to the other in such a way as
to give, them a tendency to move together but can give way when required to lift
the lever without moving the quadrant.
arm.
To one of the quadrant arms is cast or fixed a bracket which carries a two-armed
bent lever the upper arm of which carries a peg or bowl in front of the quadrant
The lower arm is curved downwards and forwards and carries a bowl which
when the quadrant arm is moved forward and downward by the quadrant pinion
this bowl comes against an inclined plane or cam surface which is attached to the
rod which connects the two copping plates together.
The action of this inclined plane or cam surface causes the upper arm of the bent
lever to push back the quadrant arm thus drawing back the lever independently
of the quadrant, and drawing back a corresponding length of the chain, so as to
dispense with the deflecting of the said chain as usually practised.
The form of the inclined plane or cam surface is such that the drawing back of
the chain, and the consequent alteration of the speed of the spindles shall be in
exact ratio to the gradually decreasing diameter of the spindles towards the
point, so that the winding-on and the tension of the yarn shall always be the same.

Improvements applicable to the "Nosing Motion" of Self-acting
Mules.
I, JONATHAN HARGREAVES, of 41, Upper George Street, Tyldesley, near Man-
chester, in the County of Lancaster, Mill Manager, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:—
This invention relates to the part of the quadrant winding motion of self-
acting mules known as the "nosing motion" the object of which is to cause the speed
of the revolution of the spindles to increase as the nose of the cop is being formed
in a ratio exactly corresponding with the gradually decreasing diameter or taper of
the spindle towards the point, so as to cause the spindle always to wind-on the
yarn at an even speed corresponding with that of the going-in of the carriage.
The manner in which my said invention is to be performed or carried into prac-
tical effect will readily be understood on reference to the sheet of drawings
hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a side elevation and Fig. 2 a front view of my
improved nosing motion, and Figs. 3 and 4 are similar views of a slight modifi-
cation thereof a being part of the headstock framing, the toothed quadrant,
and the quadrant arm which carries the screw.
For the purposes of my invention, instead of casting the quadrant and the
quadrant arme in one piece, or making them in two pieces rigidly bolted together,
as usually practised, I make them in two separate parts both turning on the same
centre or fulcrum but mounted in such a manner that they can move indepen-
dently of each other.
The quadrant b is acted upon by the toothed pinion e in the usual manner, and
its end is carried past the arm or lever e and is then bent at a right angle
or provided with a facing which as the quadrant is moved back in the direction
of the arrow holds the arm or levere in the usual position, and a coiled or other
spring is connected from one to the other in such a way as to give them a
tendency to move together, but this spring f can give way when it is required to
lift the arm or levere without moving the quadrant b.
To the quadrant arm or lever e is cast or fixed a small bracket g which carries a
two-armed bent lever the upper arm of which carries a peg or bowl i, in front of
the quadrant arm, or it may be made in the form of a cam.
The lower arm of the lever is curved downwards and forwards and carries a
bowl or projection , which, when the quadrant arm is moved forward and down-
ward by the quadrant pinion e, comes against an inclined plane or cam surface
which is attached to the rod m which joins the two copping plates together, see
plan view of this part Fig. 1a.
The action of this inclined plane or cam surface 7 causes the upper arm of the
bent lever to push back the quadrant arm or lever e thus drawing back the said
arm independently of the quadrant b, and drawing back a corresponding length of
the chain o, so as to dispense with the deflecting of the said chain as usually
practiced.
In the modification shown at Figs. 3 and 4 the small bracket g which carries
the hent arm his bolted to the quadrant b and the lower arm of this lever carries
a drum round which is coiled one end of a second chain the other end of
which is attached to a part of the " square of the spindle carriage, so that when
the latter approaches its journey's end the said chain 7 tightens and pulls over
the bent lever. The drum p is provided with a ratchet wheel and pawl s

on approaches the point of the spindle, ΟΙ this tightening of the
chain may be performed automatically by means of an auxiliary chain (see
detached plan view Fig. 3) one end of which is attached to the drum then carried
round guide pulleys and the other end fixed by a bracket to the rod m which
connects the two copping plates as before mentioned.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is-
First: The improvements applicable to the "nosing motion" of self acting
mules which consists in making the toothed quadrant and the quadrant arm or
lever in two separate parts both turning on the same centre or fulcrum in such a
manner that they either both move together or each move or be moved separately
and independently of the other.
Secondly The improved apparatus constructed substantially as herein before
described and illustrated by the annexed drawings for imparting the separate
or independent motion to the quadrant arm or lever.
