Improvements in and relating to Stop Motions for Spinning
Machinery.
I, WILHELM NEUBAUER of Cassel in the Kingdom of Prussia and German
Empire, Director of Textile Manufactory, do hereby declare the nature of this
invention, 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 a new or improved stop motion which may be applied
to any
of the existing types of spinning machinery but is specially applicable on
account of its rapid action, to the machines employed in spinning long fibred yarns
such for example as jute and flax..
The accompanying drawings, reference to which is hereinafter made, illustrate in
what manner this invention may be carried into effect.
Figure 1 represents a cross section taken through the rollers of a flyer spinning
machine.
Figure 2 shews a front elevation of that part of the machine indicated by the
arrow m Figure 1 but on a larger scale.
Referring to the drawings it will be seen that the thread a during its passage
from the rollers bb to the rollers d d passes over the guide bar c and through the
guide p.
The guide p is secured to a shaft h upon which is loosely mounted, so as
to be capable of rotation thereon, a bush or collar g. Attached to the bush g is a
downwardly extending arm or wire f the lower end of which presses against the
thread a under the influence of the weight and has a tendency to move in the
direction of the arrow f'. The weight is carried by a wire or rod k hooked at j
to a bracket formed upon the collar g, this bracket also having pivoted to it an
arm i capable of being moved into either a vertical or a horizontal position, the
latter being shewn in Figure 1, and the former in Figure 2. In its horizontal
position the arm i has such a position in front of the guide bar c that the thread has
pass between them.
to
In the event of the thread breaking the arm f moves in the direction of the
arrow and the arm i in the direction of the arrow and the broken thread is
gripped between the arm i and the bar c. As however the tbread is still delivered
by the rollers bit is necessary to prevent it becoming wrapped around the necks of
the rollers or falling down and getting entangled with the flyers. This is accom-
plished by providing a gutter or channel n fixed in such a position beneath the
rollers that the loose thread is delivered into it and can be easily recovered by
the operative who raises the arm i to the vertical position shewn in Figure 2.
The amount of pressure exerted by the wire fagainst the thread a can be adjusted
to any desired extent by altering the position of the hook by which the weight / is
attached to the collar g. This hook may preferably be screwed in and out.
Owing to the slight pressure exerted by the wire f the thread suffers no injury
during its passage through the stop motion mechanism.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1. A stop motion for spinning machinery consisting of the weight controlled
wires or arms f and i and the receiving trough or gutter n, all constructed arranged
and operating substantially as hereinbefore described and as illustrated by the
accompanying drawings
