Year: 1884

page_text: We THOMAS HENRY RUSHTON, Machine Maker of Kay Street Works, Bolton in
the county of Lancaster, and EDWARD FAIRHURST, Foreman, of the same place
do hereby declare the nature of said invention for "AN IMPROVED DEVICE, FOR
PREVENTING THE CARRIAGE GEAR OF SPINNING MULES FROM UNGEARING WHILST
MAKING THE OUTWARD RUN to be as follows :-
The object of our invention is to prevent the carriage gear of self-acting mules
from ungearing, whilst making the outward run.
In performing our invention we employ a hook, catch, or bolt, that will rest
under the carriage gear lifting lever, and so arranged that the can or long lever
which operates the said lever will act on the hook, catch, or bolt, & move it away
from & release the lever when the cam or long lever changes before the carriage
commences its inward run.
The hook is hung so that it will swing, or the catch or Bolt is so fitted that it
will move under the end of the lever when the cam or long lever ceases to act
on it.
We suspend from the carriage gear lever another hook or catch which rests
under the lifting end of the carriage gear lifting lever, and holds the two levers
together: this book or catch can be moved to one side when it is necessary to
change the gain wheel,

We THOMAS HENRY RUSHTON, Machine Maker, of Kay Street Works, Bolton,
in the County of Lancaster, and EDWARD FAIRHURST, Foreman, of the same place
do hereby declare the nature of said Invention for AN IMPROVED DEVICE FOR
PREVENTING THE CARRIAGE GEAR OF SPINNING MULES FROM UNGEARING WHILST
MAKING THE OUTWARD RUN, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
The object of our Invention is to prevent the carriage gear of self-acting mules
from ungearing whilst making the outward run.
In performing our Invention we employ a hook, catch or bolt that will rest
under the carriage gear lifting lever and so arranged that the cam or long lever
which operates the said lever will act on the hook, catch or bolt and move it away
from and release the lever, when the cam or long lever changes before the carriage
commences its inward run.
The hook is hung so that it will swing or the catch or bolt is so fitted that
it will move under the end of the lever when the can or long lever ceases to act
on it.
We suspend from the carriage gear lever another hook or catch which rests
under the lifting end of the carriage gear lifting lever and holds the two levers
together this hook or catch can be moved to one side when it is necessary to
change the gain wheel.
And in order that our Invention may be fully understood and readily carried
into effect we will proceed to describe the accompanying Sheet of Drawings, refer-
ence being had to the figures and letters marked thereon.
Similar letters refer to similar parts throughout the several views.
Figs. 1 and 2 show the levers and hooks in the relative positions they occupy
just before the mule carriage commences its inward run. Fig. 3 shows the relative
positions of part of the carriage gear lifting lever, its hook and the long lever after
backing off and during the inward run of the carriage. Fig. 4 is a similar view to
Fig. 3 illustrating the relative positions of the aforesaid parts during the outward
run.
In these views, a is the carriage gear lifting lever; b is the carriage gear lever:
c the hook that rests under the end of the lever a as shown in Fig. 4; d is the
long lever shown in Figs. 1 and 2 in the position it occupies when the carriage has
completed its outward run and before backing off, the hook c having been moved
from under the carriage gear lifting lever a, and the said lever depressed by the
long lever d, which is made and acts as usual to raise the carriage gear lever b and
to lift the pinion e (which carries on the boss the gain wheel e¹) out of gear with
the back shaft wheel f; g is a hook suspended from the carriage gear lever b and
resting under the carriage gear lifting lever a in order to hold the said levers
together.
The hook c holds the carriage gear lifting lever a as shown in Fig. 4 while the
mule carriage is making the outward run and the carriage gear lever b (not shown
on Fig. 4), is held down and the pinion e kept in gear with the back shaft wheel f
until the mule carriage has completed its outward run when the long lever & moves
the hook c aside and then depresses the carriage gear lifting lever a, as usual,
thereby raising the carriage gear lever b and lifting the pinion e out of gear with
the back shaft wheel f. The hook g is moved from under the carriage gear lifting
lever a, when the carriage gear lever b is to be swung into a vertical position to
change the gain wheel e¹ or pinion e.

page_text: Figs. 5 and 6 show our Invention applied to a mule carriage in which (as is
frequently the case) a cam shaft d¹ is used in place of the long lever d for depressing
the carriage gear lifting lever a.
Fig. 7 shows a spring bolt c¹ which may be used if more convenient, in place of
the hook c.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed.
We declare that what we claim is-
1. The device for preventing the mule carriage gear from ungearing whilst
making the outward run, substanially as herein set forth.
2. The combination with the carriage gear lifting lever whether operated by a
long lever, a cam or otherwise of a hook c, bolt c¹, or its mechanical equivalent,
substantially as and for the purposes herein shown and described.
