IMPROVEMENTS IN MULES AND TWINERS
Year: 1882

page_text: LETTERS PATENT to John Wain foreman in the employment of Messieurs,
Curtis Sons and Company of Manchester in the County of Lancaster for an
invention of "IMPROVEMENTS IN MULES AND TWINERS."
PROVISIONAL SPECIFICATION left by the said John Wain at the Office
of the Commissioners of Patents on the 25th March 1882.
JOHN WAIN, Foreman in the employment of Messieurs Curtis Sons and Company
of Manchester in the County of Lancaster.. " IMPROVEMENTS IN MULES AND
TWINERS
"
My invention consists of a novel combination and arrangement of parts in the
headstock of the mule or twiner by which I am enabled to effect the backing off
as the carriage runs out.
The arrangement for giving motion to the spindles and effecting the backing off
is substantially the same as that usually employed: motion is usually communi-
cated to the drawing rollers and to the mechanism for drawing the carriage out
by a bevel wheel fixed on the rim shaft which gears with one fast on the rollo
coupling shaft: I mount on the side of the headstock an additional shaft on
which I fix a bevel wheel gearing with a wheel on the roller coupling shaft: this
additional shaft is provided with a fast and a loose pulley driven by a belt from a
pulley on the counter shaft: To traverse the strap on to or off the fast pulley to
start or stop the additional shaft as required I lengthen the change lever so that
its end will rest under and act on a lever connected to the strap guide of this
shaft.
To stop the motion of the spindles I attach to the carriage a stop piece which as
the carriage moves out acts on an adjustable stop placed on a rod connected to the
ordinary strap guide through which the motion of the spindles is stopped and the
backing off friction cones are allowed to come into contact.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said John Wain in the Great Seal Patent Office on the 25th September
1882.
JOHN WAIN, Foreman in the employment of Messieurs Curtis, Sons and Company
of Manchester in the County of Lancaster. "IMPROVEMENTS IN MULES AND
TWINERS"
My invention consists of a novel combination and arrangement of parts in the
headstock of the mule or twiner by which I am enabled to effect the backing off
as the carriage runs out.
The arrangement for giving motion to the spindles and effecting the backing-off
is substantially the same as that usually employed: motion is usually communi-
cated to the drawing rollers and to the mechanism for drawing the carriage out
by a bevel wheel fixed on the rim shaft which gears with one fast on the roller
coupling shaft I dispense with the bevel wheel on the rim shaft and I mount on
the side of the headstock an additional shaft on which I fix a bevel wheel gearing
with a wheel on the roller coupling shaft: this additional shaft is provided with a
fast and a loose pulley driven by a belt from a. pulley on the counter shaft thus
allowing the outward run of the carriage to be completed after the rim shaft has
been reversed. To traverse the strap on to or off the fast pulley to start or stop
the additional shaft as required I lengthen the change lever so that its end will
rest under and act on an elbow lever connected to the strap guide of this shaft.
The change lever is actuated in the usual manner by a cam on the cam shaft.
To stop the motion of the spindles I attach to the carriage a bracket carrying
a bowl which as the carriage moves out passes under and lifts an adjustable stop
secured on a rod connected to the ordinary strap guide and allows the strap to be
moved on to the loose pulley by which the motion of the spindles is stopped and
the backing-off friction cones are allowed to come into contact before the carriage
has completed its outward run.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 is an elevation and Fig. 2 is a plan of part of a mule or twiner to which
.my invention is applied.
a is the roller coupling shaft which transmits motion to the drawing rollers: on
this shaft is fixed the bevel wheel b which gears into the bevel pinion c fast on the
auxiliary shaft & which turns in suitable bearings fixed to the headstock: on the
shaft.d is a fast pulley e and a loose pulley e¹. driven by a strap from the counter
shaft is the cam on the cam shaft f¹ (see Fig. 2) which in revolving depresses
the end of the change lever g in the usual manner I lengthen this lever so that one
end of it may extend under the horizontal arm of an elbow lever, h to the vertical
arm of which is fastened the strap guide h¹ which traverses the. strap on to the
loose pulley e' when the cam depresses the further end of the lever g and causes
the other end to raise the horizontal arm of the elbow lever On the lever his
a weight to bring it down and move the strap again on to the fast pulley e when
the cam, raises the further end of the lever g: i is an antifriction bowl fitted on a
stud fixed to a bracket on the carriage: when the carriage runs out the bowl i is
moved under an adjustable plate or projection j secured on the rod thus lifting
the rod and allowing it to slide through the bracket which supports it at one
end: the other end of the rod k is connected to the lower end of a vibrating
lever m to the upper end of which is fixed the strap guide m¹; to the lower part

page_text: of the lever m is also attached a spring n which when the rod is raised by the
bowl i moves the lever m so as to traverse the strap from the fast pulley o to the
loose pulley o¹ on the rim shaft and allow the friction cones to come in contact.
I lengthen the depressing lever p on the carriage so that it may act on the
backing-off rod u earlier in order to put the backing-off into gear before the
carriage has completed its outward run.
Having stated the nature of my invention and described the manner of
performing the same.
I declare that I claim.
The auxiliary shaft d for communicating motion to the roller coupling shaft and
to the carriage so that the rollers may rotate and the carriage complete its outward
run after the rim shaft has been reversed substantially as shown and described.
In witness whereof I the said John Wain have hereunto set my band and
seal this twenty-first day of September One thousand eight hundred
and eighty two.
