PROVISIONAL SPECIFICATION.
Improvements in Spinning Mules and Twiners.
I, JONATHAN HARGREAVES, of 41, Upper George Street, Tyldesley, in the
County of Lancaster, Mill Manager, do hereby declare the nature of this in-
vention to be as follows:--
This invention relates to apparatus used on "long lever" mules and twiners
for "changing" the long lever of the mule or twiner as the carriage reaches the
end of its outward or inward run or stretch.
"
Instead of causing the outer end of the "long lever to rise or fall for such
purpose by the complicated mechanism at present employed I provide a weighted
link or bar the upper end of which is slotted, and in the slot is engaged a peg
pin or bowl fixed to the end of the "long lever," and the lower end of the said
weighted link or bar is pivotted or equivalently connected to a suitable lever
beneath. The last named lever is pivotted at or near its centre and at the inner
end thereof is an incline.
Upon the carriage square I fit a bracket or fixed arm carrying a bowl or stud
in such a position that when the carriage is say about eighteen inches from the
end of its stretch, this bowl or stud comes in contact with the incline on the lever
last named and causes its inner end to be forced downwards. The other end
rises carrying with it the weighted link or bar, which is provided with a spring
fitted immediately beneath the "long lever," which displaces or compresses the
spring as it is raised with the link or bar. I prefer to use a spiral spring let
into a socket in the enlarged or weighted part of the link or bar, and to provide
the upper end of the spring with a headed bolt or spindle which comes in con-
tact with the underside of the long lever, and thus compresses the spring as
the weighted link or bar is raised.
"
The long lever' is then released (by the displacement of the usual catch
or latch) when the end of the stretch has been reached, and the spring helps
to raise the long lever quickly, and so stop the drawing out mechanism.
The carriage is taken in as usual, and when it has reached the end of its in-
ward run, the inner end of the "long lever" is released by the usual mechanism
or an equivalent device, and the weighted link or bar above described will pull
down the outer end of the "long lever," as it will then be hanging on the peg pin
or bowl thereof, and the motions will be changed again.
The changing of the "long lever" is performed more quickly and with much
less exertion or power by the above mechanism, than was the case when em-
and
ploying the complicated arrangement of wheel, crank pin and "pick axe
other levers now commonly in use.

I, JONATHAN HARGREAVES, of 41, Upper George Street, Tyldesley, in the
County of Lancaster, Mill Manager, do hereby declare the nature of this in-
vention 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 apparatus used on "long lever" mules and twiners
for changing" the long lever of the mule or twiner as the carriage reaches
the end of its outward or inward run or stretch, and the same will be readily
understood on reference to the annexed drawing which is a side elevation of
so much of a spinning mule as is necessary to illustrate my invention.
Instead of causing the outer end of the "long lever" a to rise or fall for the
purpose above stated by the complicated mechanism at present employed, I
provide a weighted link or bar 6 the upper end of which is slotted as shewn,
and in the slot is engaged a peg pin or bowl c fixed to the end of the "long
lever"
a, and the lower end of the said weighted link or bar b is pivotted or
equivalently connected to a suitable lever d beneath. The last named
lever d is pivotted at or near its centre at d, and at the inner end thereof is an
incline d
The
Upon the carriage square e I fit a bracket e¹ or fixed arm carrying a bowl
or stud e² in such a position that when the carriage is say about eighteen inches
from the end of its stretch, this bowl or stud e² comes in contact with the
inclined on the lever d and causes its inner end to be forced downwards.
other end rises carrying with it the weighted link or bar b, which is provided
with a spring 1 fitted immediately beneath the "long lever" a, which displaces
or compresses the spring 61 as it raised with the link or bar b. I prefer to
use a spiral spring as shewn let into a socket in the enlarged or weighted
part of the link or bar b, and to provide the upper end of the spring b' with a
headed bolt or spindle 63 which comes in contact with the underside of the long
lever a, and thus compresses the spring b' as the weighted link or bar bis
raised.
The "long lever" a is then released (by the displacement of the usual
catch or latch d) when the end of the stretch has been reached, and the
spring helps to raise the long lever a quickly, and so .stop the drawing out
mechanism..
The carriage is taken in as usual, and when it has reached the end of its
inward run, the inner end of the "long lever" is released by the usual mechanism
or an equivalent device, not shewn on the drawing, and the weighted link or
bar b above described will pull down the outer end of the "long lever" a,
as it will then be hanging on the peg pin or bowl c thereof or preferably (as
shown) by a projection 6* resting on the end of the long lever a, and the motions
will be changed again.
The changing of the "long lever" is performed more quickly and with much
less exertion or power by the above mechanism, than was the case when em-
ploying the complicated arrangement of wheel, crank pin and "pick axe
other levers now commonly in use.
" and
It will be evident that if preferred instead of weighting the link or bar bas
shown the latter may be provided with a suitable spring connected, say, to the
floor and tending to pull down the said link or bar.

page_text: 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:
The combination with the long lever of a spring and weighted or equivalently
fitted link or bar supported and actuated by a fixed lever and incline and a
bowl or peg on the carriage square substantially as and for the purpose herein-
before described.
