COMPLETE SPECIFICATION.
Improvements in Self-acting Mules and Twiners.
I, JOHN CLEGG, of the firm of Asa Lees and Company Limited, Soho Iron
Works, Oldham, in the County of Lancaster, Manager of Mule Department, 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 improvements in self acting mules and twiners particularly
to those driven by a countershaft and my improvements consist essentially in com-
bining with the usual inclined lever and strap relieving rod a hand or treadle stop
motion whereby the attendant is enabled to move from the fast pulley to the loose
pulley the down strap from the countershaft to the rim shaft and latch the same on
the loose pulley on the rim shaft without interfering with the ordinary pulling off
and setting on handle.
And in order that my invention may be fully understood and readily carried into
effect I will describe the same with reference to the accompanying sheet of drawings
in which-
Figure 1 is an elevation and Fig. 2 a plan of the inclined lever and part of the
strap relieving rod of a self acting mule with which is combined according to my
improvements a lever stop motion to be worked by hand or foot.
In these views A is the ordinary inclined lever which is depressed by a stop on
the mule carriage as the latter approaches the end of its outward run and by means
of the strap relieving motion rod B shifts the down strap from the countershaft off
the fast pulley and on to the loose pulley on the rim shaft.
In carrying my improvements into effect I connect a link C to the strap relieving
motion rod B and to the link C 1 pivot a lever D which is fulcrumed at E to the
framing and is weighted at D' to keep the other end of the lever D normally raised
and out of action as shown; but when the end of the lever D is depressed by hand
or foot it operates through the link C and strap relieving motion rod B and thus
draws the down strap from the countershaft off the fast pulley and on to the loose
pulley on the rim shaft. When in this position the lever D is latched by means of
a latch lever F which is fulcrumed at G and falls over and engages a lug or pro-
jection D2 on the lever D and so prevents the latter from rising.
By these means the strap is kept upon the loose pulley until the latch lever F
is pulled off the lug D thereby allowing the weight Ď₁ to raise the other end
of the lever D and through the link C and rod B to move the strap on to the
fast pulley.
It will be readily understood that the details herein shown and described may
be varied or modified without departing from the nature of my invention which
consists as already stated in combining a stop motion operated by a hand
or foot with the inclined lever and rod of the ordinary automatic strap relieving
motion.
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 :-
The combination with the ordinary automatic strap relieving motion, of a hand or
foot stop motion substantially as and for the purposes herein set forth.
