PROVISIONAL SPECIFICATION.
Improvements in the Governing Motion of Mules or Twiners.
I, JOHN BROOKS of 5 Milo Street, Bolton in the County of Lancaster,
Spinning Overlooker, do hereby declare the nature of my said invention to be as
follows:-
This invention relates to improvements in the governing motion of mules or
twiners for spinning cotton and other fibrous materials and consists in providing a
governing motion that will operate at any point during the inward run of the mule
carriage to ensure even and uniform winding, and the prevention of waste and
snarls during the formation of the cop. To the mule room floor I attach by fixings
one or more pulleys round and over or under which a band or cord passes to a
pulley on the quadrant shaft or centre This band or cord passes over or round a
pulley mounted on a shaft or centre on the mule carriage. On this shaft or centre
is fixed in any convenient manner a cam with one or more projections or stops.
On the front of the mule carriage is mounted a slide bar or fixing in which
operates a slide attached by a pulley and cord to adjustable levers or quadrants
mounted on the faller rods. When the mule carriage has completed its outward
run the slide drops by the action of the faller rods and places the bottom end of
the said slide in the path of the cam and its projections, by which the revolving
action of the latter is arrested. The arresting or stoppage of the cam causes the
band or cord to be operated or moved so as to rotate the pulley on the quadrant
shaft or centre, by which the position of the winding chain on the quadrant arm is
automatically regulated according to the building or formation of the cop.

Improvements in the Governing Motion of Mules or Twiners.
I, JOHN BROOKS, late of 5 Milo Street, and now of 20 Norwood Grove, Bolton.
in the County of Lancaster, Spinning Overlooker, do hereby declare the nature of
my said invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement :-
This invention relates to improvements in the governing motion of mules or
twiners for spinning cotton and other fibrous materials and consists in providing a.
governing motion that will operate at any point during the inward run of the
mule carriage to ensure even and uniform winding, and the prevention of waste.
and snarls during the formation of the cop. To the mule room floor I attach by
fixings one or more pulleys round and over or under which a band or cord passes
to a pulley on the quadrant shaft or centre. This band or cord passes over or
round a pulley mounted on a shaft or centre on the mule carriage. On this shaft
or centre is fixed in any convenient manner a cam with one or more projections or
stops. On the front of the mule carriage is mounted a slide bar or fixing in which
operates a slide attached by a pulley and cord to adjustable levers or quadrants
mounted on the faller rods. When the mule carriage has completed its outward
run the slide drops by the action of the faller rods and places the bottom end of
the said slide in the path of the cam and its projections, by which the revolving
action of the latter is arrested. The arresting or stoppage of the cam causes
the band or cord to be operated or moved so as to rotate the pulley on the
quadrant shaft or centre, by which the position of the winding chain on the
quadrant arm is automatically regulated according to the building or formation of
the con.

page_text: Fig. 1 is a side elevation of so much of a self-actor mule as is necessary to
illustrate my invention.
Fig. 2 is a plan of same.
Fig. 3 is a part front view of mule carriage with my invention applied.
Fig. 4 is a section through line A¹ B' in Fig. 3, and Figs. 5 to 8 inclusive are
side elevations of cam with 2, 4, 6, and 8 stops or projections.
The fixings A. are attached to the mule room floor, and are fitted with the
centres B on which are mounted the pulleys C. To the mule carriage D is
secured the fixing E fitted with the centres F and G carrying the pulleys H
and I respectively. The endless band J is guided over and under the before
mentioned pulleys to the pulley K on the quadrant shaft or centre L. On the
centre F is mounted the pulley H to which is attached the cam M which can
be provided with two or more projections or stops N as shown in the drawings.
To the fixing E is attached the slide-bar O secured to the front of the mule
carriage D.
In the slide-bar O is mounted the slide P, on the upper end of
which is the pulley Q and cord or band R to connect it with the adjustable or
other levers S and T on the faller rods V and W. The levers S and T can
be of any suitable or convenient form, and may be constructed as quadrants if
desired.
In case the tension on the yarn is too great when the mule changes the
copping faller W operates in the direction indicated by the arrow in Fig. 1 and
lowers or drops the slide into the path of the stops or projections N on the
cam M, and arrests the rotary motion of the latter which causes the band or cord J
to be moved or traversed to turn the pulley K on the shaft L carrying the
quadrant arm X, by which the ordinary winding chain attached to the screw Y
on the quadrant arm X is operated. Immediately the correct tension on the yarn
is attained the faller rods are operated by the ordinary appliances, which lift the
slide P out of action with the cam M and thus stops the movement of the band or
cord J. The band or cord R and the pulley Q allow the failer rods V and W to
operate in the usual manner without interfering with the governing motion. The
operation of the slide P varies every inward run of the mule carriage D according
to the varying tension on the yarn, and is at liberty to operate at any part of the
said inward run of the mule carriage, the same being regulated by the movements
of the faller rods and their connections. The pulley K is provided with the usual
ratchet, pawl, and spring in the casing Z for the purpose of preventing the shaft
or centre being rotated in the wrong direction. When the cop bottom is formed
or completed the slide P, by the raised or altered position of the levers S and T or
their equivalents on the faller rods demanded by the increased length of cop, is
raised clear of the cam M, thus leaving the apparatus stationary until the next set
of cops are being started.
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 :-
:-
1. The general arrangement, construction, and combination of parts composing
my improvements in governing motions of mules and twiners, as herein before
described and as illustrated in the annexed drawings.
2. In governing motions for mules and twiners the combination of the cam,
slide-bar, and slide, the latter being coupled to the faller rods so as to operate on
the cam at any point of the inward run of the mule carriage according to the
tension on the yarn, to ensure even and uniform winding and to prevent waste and
snarls during the formation of the cop, substantially as described.
