We, JAMES TAYLOR, of Stalybridge, Machinist, and CHARLES WILD, of
Oldham, Doubler, both in the County of Lancaster, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN SELF-ACTING MULES FOR
SPINNING AND DOUBLING," to be as follows:-
Our Invention consists in new combinations of self-acting mechanism for
mule spinning and doubling. The spindles, carriage, and fallers, and the
drawing rollers are of ordinary arrangement. The spindles are driven from a
"rim pulley" on the "first motion shaft;" the "carriage" is drawn out and
taken in by means of bands, drums, and scroll drums, similar to those used in
ordinary mules. On the completion of each "stretch," the driving belt is
traversed from the fast to the loose driving pulley, the "taking-out motion" is
put out of geer, and the "backing-off motion " is put into geer, by the direct
action of the carriage on suitable levers. When the "backing-off motion'
is brought into geer, a ratchet and click arrangement on the "rim shaft"
causes a pin, when the "backing-off" is to be completed, to lift a lever, which
puts out of geer the "backing-off motion," and brings into geer the "taking-
in motion." This ratchet and click arrangement is also connected by a chain
with a shaft that operates the "fallers," as herein-after described.
fulcrum of the lever upon which the pin of the ratchet and click arrangement
acts is mounted on a piece carried by a screw, to which screw part of a turn
is given every "stretch," so that the pin of the ratchet and click arrangement
will strike the lever sooner each "draw," and thus diminish the amount of
backing-off" as the cop builds. The "winding on" of the thread is
The

in shaft," the other (which is driven by the first) being connected with the
"rim shaft" by a click and ratchet arrangement, so that the cone can drive
but will not be driven by the "rim shaft." The spindles have an uniform
speed as the "carriage" goes in, but this uniform speed is altered at every
"stretch" during the formation of the bottom of the cop by changing the
position of the belt which passes between the cone drums; this is done by
mounting the belt guides on a screw that is partly rotated every "stretch"
while the bottom of the cop is being made, but when this is done the belt
remains in the same place on the cones while the remainder of the cop is
formed. The "fallers" are acted upon to distribute the thread when
"winding on" by a "shaper rail," which is made into a lever, the fulcrum of
which is placed under the roller beam or thereabouts, the other end of the
"shaper lever" being acted upon by a crank fixed on a shaft, herein-before
mentioned, which has motion from a chain connected with the ratchet and
click arrangement that is brought into action by the "backing-off motion."
The crank on the shaft lifts the end of the "shaper lever," which acts to
bring down the "fallers" to the required position for "winding on;" the crank
shaft is held by a click in the position in which it is brought by the chain
before mentioned, a further movement being imparted to it by a hook attached
to the "carriage" when it begins to move in, which movement lifts the
"shaper lever" to its greatest height, at which point a lever catch holds the
crank shaft till the "carriage" has been "put up," at which moment the carriage
strikes upon a lever which is connected with the lever catch that releases it
from the crank shaft, consequently the crank allows the "shaper lever" to fall
to its lowest position, this movement of the crank shaft also traverses the driving
belt on to the fast pulley. The going in of the carriage acts directly to put
the "taking-in motion" out of geer, and the "taking-out motion" into geer,
and also the drawing rollers. The going in of the carriage when "put up"
also releases the "fallers," and allows them to rise. The raising of the
"fallers" as the cop builds is accomplished by means of a lever having its
fulcrum on the "faller shaft," upon this lever or arm a screw is mounted
which carries a pin that is changed in position as the cop builds by giving a
partial rotation to the screw every "stretch." This adjustable pin is connected
with a bowl or stud which runs upon the "shaper lever."
