PROVISIONAL SPECIFICATION.
Improvements in Selfacting Mules and Twiners.
We, JOSEPH VAUGHAN, of 123, Whiteacre Road, Spinning-master, and
THOMAS HAUGHTON, of 37, Richmond Street, Manager, both of Ashton-under-
Lyne, in the County of Lancaster, do hereby declare the nature of this invention to
be as follows:-
This invention relates to a combined brake and starting motion applicable for
selfacting mules and twiners, where it is required to suddenly stop and re-start a
certain portion thereof or which by means of bands, straps or ropes imparts
rotary motion to spindles, whereby a great deal of time and wear and tear is
saved.
To this end our invention consists in employing a helical spring, the inner end
of which is directly or indirectly secured to the rotary part which imparts motion,
by means of bands or their equivalents to the aforesaid spindles and the outer end
of which is secured to a friction pulley revolving loosely directly or indirectly on
the aforesaid rotary part and over the periphery of which is hinged a brake lever
brought into contact with the said friction pulley when required by suitable
connections operated from any movable part of the selfacting mule or twiner.
In applying our invention we employ the same on the tin roller pulley keyed on
the tin roller shaft, which requires to be stopped from two to five times every
minute when the mule or twiner is at work and to be reversed, which is termed
backing off."
6
On the boss of the pulley which is fixed on the tin roller shaft we arrange to
rotate loosely a friction pulley forming a box or cover for the helical spring
aforesaid by fitting it against the side of the tin roller pulley. The latter is
formed with a flange which projects into the said friction pulley and to which is
secured the inner end of the said helical spring, whilst the outer end is secured to
the aforesaid friction pulley, the said helical spring being of sufficient length to
be wound up tight by the brake lever when applied to the friction pulley and to be
held firm by it until the tin roller has made one revolution backwards for the
purpose of "backing off."
The said brake lever is applied to the friction pulley through the pull of the
stop rod of the "backing off" friction which is jointed to a bell crank lever,
connected by means of a spiral spring to a lever having a bowl resting on an
incline rendered adjustable on the free end of the brake lever.
"
At the moment of "backing off" the helical spring is permitted to uncoil to its
former state ready for the next draw after which the whole motion is set at
liberty by the action of the "monkey tail lever which at the same time frees
the "backing off cone" by pressing on the bell crank lever connected to the stop
rod of the "backing off" friction, thus working the latter and the tin roller
simultaneously, facilitated by the medium of the aforesaid helical spring.

Improvements in Selfacting Mules and Twiners.
We, JOSEPH VAUGHAN, of 123, Whiteacre Road, Spinning-master, and
THOMAS HAUGHTON, of 37, Richmond Street, Manager, both of Ashton-under-
Lyne, in the County of Lancaster, 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 relates to a combined brake and starting motion applicable for
selfacting mules and twiners where it is required to suddenly stop and re-start
a certain portion thereof,-which by means of bands, straps or ropes imparts
rotary motion to spindles, whereby a great deal of time and wear and tear is
saved.
To this end our invention consists in employing a helical or other suitable
spring, one end of which is directly or indirectly secured to the rotary part which
imparts motion by means of bands or their equivalents to the aforesaid spindles,
and the other end of which is secured to a friction or brake pulley revolving
loosely directly or indirectly on the aforesaid rotary part and over the periphery
of which is hinged a brake lever brought into contact with the said friction pulley
when required by suitable connections operated from any movable part of the
selfacting mule or twiner.
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a side view of that portion of the head stock of a selfacting mule or
twiner to which our improvements are applied.
Fig. 2 is a cross section of the tin roller pulley and brake, shown in Fig. 1, and
Figs. 3 & 4 are respectively a sectional end view and partly a cross section and
partly a side view of a modification of the tin roller brake.
In carrying out our invention and referring to the figures generally a is a part of
the head stock of a selfacting mule or twiner, 6 the tin roller shaft, c the tin roller
pulley. The latter is keyed upon the tin roller shaft b which requires to be stopped
from two to five times every minute when the mule or twiner is at work and to be
reversed, which is termed "backing off."
On the boss c¹ of the pulley c we arrange to rotate loosely a friction or brake
pulley & retained laterally in position by means of the collar 6 and forming a box
or cover for the helical or other spring e by fitting it against the side of the tin
roller pulley c. The latter is formed with a flange or rim c which projects into
the friction or brake pulley d and to which is suitably secured the inner end of
the helical or other spring e, whilst the outer end is secured to the frictiou or brake
pulley d.
In connection with the periphery of the friction or brake pulley d we employ
upon a stud a¹ a brake lever f which when applied to the friction or brake pulley d
prevents the same from rotating and causes the spring e to be wound up tightly and
held firm together until the tin roller or shaft b has made one revolution backwards
for the purpose of "backing off."
In lieu of a helical spring e, as shown in Figs. 1 & 2, any other suitable kind of
spring or springs may be used, for instance a spiral spring e secured in a similar
manner to the tin roller pulley c and the friction or brake pulley d, as shown in
Figs. 3 & 4.
The brake leverf is applied to the friction or brake pulley d through the pull
of the stop rod g of the backing off" friction of the mule or twiner (not shown),
which rod is jointed to a bell crank lever h having its fulcrum at a². The bell
crank lever his connected by means of a spiral spring i to a lever k fulcrumed on a

page_text: stud a³ and having a bowl A resting on an incline f' rendered adjustable on the free
end of the brake lever f, which is under the influence of a spring m.
"
At the moment of "backing off" the helical or other suitable spring e is
permitted to partially uncoil ready for being wound up tight again for the next
draw, the whole motion being set at liberty by the action of the "monkey tail"
lever m which at the same time frees the " backing off cone of the mule or
twiner (not shown) by pressing upon an adjustable bowl on the bell crank lever h
which causes the stop rod g to work the "backing off friction" (not shown) and
the tin roller brake pulley d to be released. The spring e then uncoils to its former
state ready for the next draw.
In lieu of arranging the brake lever f to act upon the periphery of the friction
or brake pulley d it may be shaped so as to be applied against the side thereof.
It will be understood that we do not confine ourselves to the exact details, form
or position of the various parts as the same may be altered without departing from
the nature of our invention.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim, is-
"In selfacting mules and twiners."
1st. The general construction and combination of parts constituting our
improvements operating substantially as and for the purpose specified.
2nd. The combination of the tin roller pulley cor part from which rotary motion is
imparted to the spindles of the mule or twiner with a brake, the pulley d of which
is connected to the tin roller pulley c or other part aforesaid by means of a spring
or springs e adapted to be wound up and permitted to uncoil at the moment of
"backing off," substantially as and for the purpose set forth.
3rd. The means described in the preceding claim in combination with suitable
connections between the brake lever f and stop rod g, substantially as and for the
purpose set.
