I JOSHUA HOLDSWORTH of 988 Leeds Road Bradford in the County of York
Overlooker 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 an arrangement of mechanism which consists of two
principal parts of which one is an indicator to indicate the number of times the frame
is doffed, the other an automatic stop motion for the purpose of stopping the frame
when the doffing is required to take place.
To carry out my Invention I secure a worm on the tappet plate shaft or the heart
shaft this worm actuates a change wheel mounted upon a vertical stud fixed to a
bracket secured to the end of the frame. The change wheel revolves with and on the
same stud as a bevil wheel having one or more pins, with bevilled tops secured on
the upper side. This bevil wheel engages with another bevil wheel having one more
teeth in its periphery, and also having numerals marked in a circle within the
circumference.
This gearing is so arranged that when the bevil wheel having the numerals marked
upon its surface has made one revolution the bobbins are filled. The frame is then
stopped by means of the pin or pins before mentioned coming in contact with one end
of a lever the other end of which is held in a notch cut in the wheel for knocking off,
which wheel is mounted at the side of the frame at a suitable distance from the gearing
herein before referred to. To the inside of this wheel I fit a coiled spring so arranged
that when the lever comes in contact with the pins, the other end is thrown out of the
notch in the wheel which is caused to revolve by means of the spring on a screw, to
one end of which screw is attached the belt fork, so that when the hand wheel revolves
it forces the screw out and thereby throws the strap from the fast on to the loose
pulley.
In order to enable my invention to be fully understood I will proceed to describe
the same with reference to the accompanying drawings in which Figure 1 represents

page_text: a front elevation of my improved automatic stop motion and indicator attached to the
end of a Spinning Frame.
Figure 2 represents a plan of the same.
Figure 3 represents an enlarged view of the indicator.
Figure 4 represents an enlarged view of part of the knocking-off apparatus.
Similar letters refer to similar parts in each Figure.
On the tappit plate shaft or heart shaft A is fixed the worm B which gives motion
to the worm wheel C on the boss of which is secured the bevil wheel D having a pin
or pins M. fixed into its upper side. The bevil wheel D actuates the bevil wheel E
which has one more tooth than the wheel D and having numbers marked upon it
opposite every fifth tooth as 5, 10, 15 and so on, when this wheel has made one
revolution the bobbins in the frame will be full and ready for doffing. The frame is
then stopped by means of the pin or pins E coming in contact with and lifting one
end of the lever F (which works on the stud G) and thereby throws the other end of
the lever on which is a catch out of the notch N in the wheel H which is fixed to the
end of the screw J. The wheel H works at the side of the box K within which box
is the coiled spring I. one end of which is fixed to the box K and the other end to the
boss of the wheel H, which to set it in operation requires to be turned round a few
revolutions to wind the spring up, before the catch on the end of the lever F is placed
in the notch N.
The Spring being coiled up in its box is ready to act as soon as the end of the
lever F is withdrawn from the notch N. The Spring being thus liberated causes the
wheel H and the screw J to revolve which screw operating in the internally screwed
cylinder (to which is attached the belt fork P throws the belt off the "fast" on to
the "loose" pully thereby causing the machine to stop.
By means of the arrangement hereinbefore described the dial or indicator marked
upon the bevil wheel E will indicate the number of times the frame has been doffed.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The mechanism for indicating the number of times a Spinning Frame is doffed,
such mechanism consisting of the worm B, the worm wheel C, the bevil wheel D, the
pin M. and the bevil wheel with dial E, all substantially for the purpose, and as herein
described and represented in the accompanying drawings.
2. The automatic stop motion for a Spinning Frame consisting of the mechanism
referred to in Claim 1 above combined with the lever F, the spring and spring box K
the hand wheel H and the screw J all for the purpose and operating in the manner
described and represented in the accompanying drawings.
