Improvements in or relating to Spinning and Twisting Machinery.
We, EDWARD HOLLINGWORTH, of Hutchinson, Hollingworth and Company, Limited,
of Dobcross, in the County of York, Machine Makers, and WILLIAM MITCHELL, of
Colne Road, Huddersfield, in the County of York, Manager, do hereby declare the
nature of this invention to be as follows:-
This invention relates to spinning and twisting machinery and the object of our
improvements is, firstly; to provide means for applying brake power to each
individual spindle so that the attendant can, by slight pressure of the foot, stop any
one spindle at will, and secondly; to employ a system of change gearing for driving
the tin cylinder from which the spindles derive their motion, whereby the motion of
each tin cylinder on the machine and consequently that of the spindles driven there-
from can be reversed easily and expeditiously at will without disturbing the driving
bands or tapes.
In carrying out the first part of our invention, we provide in conjunction with each
spindle an arm or lever weighted at its lower end and having a brake yoke or strap
at its upper end. Close to the upper end of said arm or lever are two horns or
projecting studs, which are adapted to fit into open bearings formed on or attached
to the rail of the machine which is adjacent to the wharle of the spindle, the said
horns being of sufficient length to allow the lever or arm to centre itself with the
spindle. The arm or lever by reason of its weighted end hangs nominally in a
vertical position and clear of the spindle, but by slight pressure of the foot against
an engaging surface on the lower end of said arm it is moved on its fulcrum and
brings the yoke or brake band into contact with the spindle and immediately stops
its rotation, the leverage obtained by said arm giving great power to the
attendant.
In carrying out the second part of our invention we employ two carrier toothed
wheels carried by a bracket which is centred on the driving axis from whence the
spindles are driven and is adapted to move radially around said axis by means of a
quadrant or segmental slot or its equivalent and secured in any required position by
ineans of a nut and bolt. The primary carrier wheel is always maintained in gear
with the driving wheel or pinion and, when the bracket is in one positión transmits
motion through the secondary carrier wheel to the tin cylinder. When the motion
of said cylinder has to be reversed, instead of removing and re-arranging the driving
bands or tapes as at present, the bracket is adjusted so as to remove the secondary
carrier wheel out of gear with the toothed wheel on the tin cylinder shaft thereby
bringing the primary carrier wheel into gear with said wheel and driving it direct
through the primary carrier wheel by which means the tin cylinder is driven in a
reverse direction and the secondary carrier wheel remains idle.
A system of changeable gearing such as described is applied at each side of the
machine for operating each tin cylinder and row of spindles.
