PROVISIONAL SPECIFICATION.
İmprovements in or applicable to Self-acting Mules or Twiners.
1, WILLIAM THOMAS WATTS of the Firm of Taylor Lang & Co. Limited,
of Castle Iron Works, Stalybridge, in the County of Chester, Machine Makers,
do hereby declare the nature of the said invention, to be as follows:-
My invention relates to an improved combination and arrangement of mechanism
by which the belt, driving the mechanism which actuates the spindles, rollers and
carriage of self-acting mules and twiners can be traversed from the fast to the
loose pulley at the required point before the carriage arrives at its full stretch,
such improved mechanism being adjustable to come into operation sooner or
later, and so that it can be put entirely out of operation or operated by hand when
required.
According to my invention the ordinary belt guide lever is connected by a rod
to the lower end of a lever having its fulcrum upon a horizontal axis at the front
part and upon one side of the headstock.
The lever has a short arm at a right angle to it in which there is an adjusting
screw the end of which can act against the edge of a bent arm having its fulcrum
loose on the said horizontal axis.
This bent arm is made in two parts which are secured together by a bolt and
slots, so that the bent arm may be shortened or lengthened as desired.
When this bent arm is sufficiently depressed by the adjusting screw its bent end
will come in contact with the faller shafts on the carriage as it comes out, and the
fallers will lift the bent arm and this acting through the adjusting screw will
transmit the movement to the ordinary belt guide lever and traverse the belt from
the fast to the loose pulley.
There is a hand lever with a curved end upon a stud in the bracket carrying the
lever and the bent arm upon the horizontal axis and when this hand lever is turned
to one position it acts upon the lever on the horizontal axis and moves the ordinary
belt lever upon the loose pulley and holds it there, and when this hand lever is
moved back the ordinary belt guide lever is at liberty.

Improvements in or applicable to Self-acting Mules or Twiners.
I, WILLIAM THOMAS WATTS, of the Firm of Taylor, Lang & Co. Limited,
of Castle Iron Works, Stalybridge, in the County of Chester, Machine Makers,
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 relates to an improved combination and arrangement of mechanism
by which the belt, driving the mechanism which actuates the spindles, rollers and
carriage of self-acting mules and twiners can be traversed from the fast to the

page_text: loose pulley at the required point before the carriage arrives at its full stretch,
such improved mechanism being adjustable to come into operation sooner or
later, and so that it can be put entirely out of operation or operated by hand when
required.
According to my invention the ordinary belt guide lever is connected by a rod
to the lower end of a lever. having its:fulcrum upon a horizontal axis at the front
part and upon one side of the headstock.
The lever has a short arm at a right angle to it in which there is an adjusting
screw, the end of which can act against the edge of a bent arm having its fulcrum
loose on the said horizontal axis.
This bent arm is made in two parts which are secured together by a bolt and
slots, so that the bent arm may be shortened or lengthened as desired.
When this bent arm is sufficiently depressed by the adjusting screw its bent end
will come in contact with the faller shafts on the carriage as it comes out, and the
fallers will lift the bent arm and this acting through the adjusting screw will
transmit the movement to the ordinary belt guide lever and traverse the belt from
the fast to the loose pulley.
There is a hand lever with a curved end upon a stud in the bracket carrying the
lever and the bent arm upon the horizontal axis and when this hand lever is turned
to one position it acts upon the lever on the horizontal axis and moves the ordinary
belt lever..upon the loose; pulley and holds it there, and when this hand lever is
moved back the ordinary helt guide lever is at liberty.
The accompanying drawing is a side elevation of so much of the headstock
mechanism of a self-acting mule or twiner as will be necessary to explain my
invention.
Part only of the framing a, is shown, as parts of the framing are supposed to be
broken away and omitted to bring the drawing within the sheet and show the
mechanism on a larger scale than the size of sheet would admit of if the entire
framing were shown.
b, represents the fast driving pulley on the "rim" shaft.
the loose pulley for the driving belt.
d, is a stud in the framing forming the fulcrum for a lever d', which is made at
its upper end with a projection d², for one end of a helical spring d³, the other end
of which passes through a hole in an arm d, from the strap lever d³, and the
tension of the spring d³, is adjustable. by screw nuts on the end of the spring as
showu.
The strap lever d³, is free on the. fulcrum stud. d, and at its upper end the eye or
fork guide do, is secured for the driving. belt.
:
The strap or belt lever d³, can oscillate to and fro to the extent limited, by a
projection on the upper end of the lever d', and the helical spring d³.
This arrangement and the helical spring d³, thus allows for a sudden movement
operating upon the driving belt giving it time to follow.
The lower curved. arm.of the lever d', is jointed to. a curved junction part e, the
end of which is formed and screw tapped to receive the screwed end of a round
rod e', which can be secured when adjusted in length by a lock nut as shown.
The other end of the round rod e', enters a hole in one end of another part e², in
which it is secured by set screws as shown, the other end of which is jointed to a
stud, adjustable in a slot in the lengthway of a lever or arm f, having its fulcrum
on a stud f, carried in a bracket a', secured to the framing.
The lever or arm f, is free to oscillate upon the stud f2.
Upon one side of the lever f, on the saine stud f, there is another arm or lever g,
also free to oscillate upon the stud ƒ³, and this: lever g, is made in two parts-the
end furthest from the fulcrum, being curved upwards and this part of the arm g,
overlaps the other part of the arm, and they are connected by a bolt passing
through slots in the lengthway of the arm g, thus allowing the length of the arm
to be adjusted so that the fallers may come against the curved end of the army,
sooner or later as required, when the carriage is moving out from the rollers.

page_text: The arm f, has two projections from it, one f³, that comes upon the underside
of the arm g, and which projection f³, sustains its weight when not acted upon
by the fallers and when lifted by the handle hereinafter mentioned.
9,
The other projection from the arm f, comes above the upper edge of the lever
and is for à screw f, which screws through a hole in this projection the point of
the screw coming opposite to and more or less against the upper edge of the arm g.
The adjusting screw f, has or may have a milled_head for rotating it.
When the mule carriage comes out from the rollers, before it has arrived at its
full "stretch" the faller rollers h and A', moving with the carriage come against the
curved end of the lever g, and lift it, and this takes place sooner or later according
to the length of the lever g.
This lever g, when once adjusted is always lifted to the same extent by the
fallers (h,) and whether any movement thus given is transmitted to the belt
guide lever d', will depend upon the adjusting screw f*.
9,
If the point of the screw is drawn back so as not to touch the lever when
lifted to its highest extent by the fallers there is no action upon the belt lever d³,
but there will be more or less action upon it accordingly, as the screw f*, is adjusted,
as when its point is close upon the edge of the lever g, it transmits the full
movement imparted by the fallers to the lever f, and thus to the belt lever d³,
through the connecting parts.
The circles and h¹, in full line represent the fallers when approaching the
lever g, and are shown in dotted line at h2, h3, in their position when under the
lever g, when it is lifted by them to its full extent.
On the bracket a', carrying the fulcrum stud f2, for the levers fand g, there is a
stud kl, which can be adjusted in a horizontal slot in the bracket.
This stud k', is the fulcrum for a hand lever k, the lower end of which is cam
shaped and comes opposite the front edge of the lever or arm f
In the position in which the hand lever k, is shown in full line it is inoperative,
the lever, being then free to oscillate to move the driving belt from the fast to
the loose pulley, but when the lever handle k, is moved to the position shown in
dotted line, its cam end has come against the edge of the arm and has moved it
into the position to put the driving belt on the loose pulley c.
The lever g, acted upon by the fallers and all the parts connected with it and
transmitting movement to the belt lever d³, are shown in full line when the belt is
on the fast pulley b, and in dotted line when on the loose pulley c.
Some of the parts described are old and well known.
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 :-
:-
1. The combination of the two levers or arms (f and g) connected and adjustable
in relation to each other, substantially as and for the purpose hereinbefore described
and illustrated by the drawings.
2. The combination of the lever (f) having two projections from it one for an
adjusting screw with a lever (g) acted upon by the fallers, substantially as and for.
the purpose herein before described and illustrated by the drawings.
3. The combination and arrangement of mechanism for actuating the driving
belt from the fallers, substantially as and for the purpose herein before described
and illustrated by the drawings.
4. The combination of a hand lever (k) with the levers (f and g) substantially
as and for the purpose hereinbefore described and illustrated by the drawings.
