IMPROVEMENTS IN MULES FOR SPINNING FIBRES
Year: 1884

page_text: We JAMES SAMUEL COOKE Carpet Manufacturer and ARTHUR HARDWICK
Foreman Spinner both of Liversedge Carpet Works Liversedge in the County of
York do hereby declare the nature of the said invention for "IMPROVEMENTS IN
MULES FOR SPINNING FIBRES" to be as follows:
This invention relates to improved apparatus to be employed for the purpose of
taking up the slack of the yarn or Slubber between the condenser bobbin and the
draw roller at the same time permitting the twist to be continued in the yarn or
Slubber from the spindle to the condenser bobbin.
Apparatus for purpose aforesaid constructed according to this our said invention
comprises the use on the bottom draw roller shaft of a worm which gears with and
drives a worm wheel having teeth on the whole or on part of its circumference
(teeth and blanks) when the teeth are on part only of its circumference so that the
worm will not turn the wheel when working in the blanks, which are so arranged
that when the yarn or slubber is nipped by the draw roller the worm wheel is not
moved the latter is mounted on a stud working in a block bearing held in a bracket
by means of a spring cap to prevent the teeth being stripped out of the wheel, at
the other end of the stud is a cam disc having a pin or pins projecting from its
outer face also cam surfaces or snecks on its inner face these snecks are for purpose
of holding the worm wheel by means of a catch lever and spiral spring the latter
bringing a projection in the catch lever up to the sneck in the cam disc thus locking
the wheel in relative position with the worm when the latter is working where
there are no teeth-On the carriage is fixed a stud or pin which on the outward
movement of the carriage forces back by means of a jointed lever the catch lever
which locks the snecks of the cam disc-when released a spiral spring which is
fixed on the opposite end of the guide wire rod draws the latter forward ready for
being operated by the pins on the cam disc coming in contact with an inclined cam
surface on the end of the guide rod thus causing the guide wire to move the yarn
or slubber into a recess or groove formed in the top draw roller thus releasing the
yarn or Slubber from the nip of the top and bottom draw rollers enabling the twist
to be put in the yarn from the spindle to the condenser bobbin at the same time
taking up any slack there may be in the yarn or Slubber from the draw rollers to
the condenser;
