Improvements in Doubling and Twisting Frames.
We, MATTHEW WRIGHT, Prospect Mills, Wibsey near Bradford in the County of
York, Worsted Spinner, and EDWARD LONGBOTTOM, of Prospect Mills aforesaid,
Mechanic, 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 :-
"
In frames "
or machines for purpose aforesaid, when and after stoppage, it
commonly occurs that more or less of the trap levers, which carry the thread guides
are up, or in their tilted position, consequently on restarting, the length of "twist"
between the cap and the thread guide, is slack, or their is an excess of length,
which is not taken up, and the trap lever drawn down to its correct working position
until an excess of twist, has been put into such length, consequently, "hard twist" or
faulty yarn is made.
The object of this our invention is to ensure by automatic appliances, brought into
operation, through the use of the ordinary agency for stopping and starting the frame,
that all the trap levers, and thread guides carried by the latter shall be down, or in
their correct working position, and the making of hard twist be avoided.
From the tin cylinder, or other convenient going part, I drive by means of a tape
or band a pulley on a short horizontal shaft carried in brackets, or by the end frame,
on the other end of this horizontal shaft is a toothed wheel which drives a second
toothed wheel on another horizontal shaft on which is a worm gearing with a worm
wheel on a third horizontal shaft on which is a ratchet wheel the teeth of this ratchet
wheel supports a catch and slide piece at the top of which is a projecting lump on
which a finger rests; this finger is fast on the stop rod which is connected at each
end to the trap lever rod as ordinary. To the projecting lump on the slide piece is
fixed a chain passing over a guide pulley on the bracket which carries the slide piece,
the other end of the chain is attached to a slide working in a bracket fixed to the end
frame, the slide being operated by a screw and hand wheel. When the machine is
the finger on the trap rod is resting against the projecting lump, but when
the ratchet whee! on the horizontal shaft has made a part revolution the catch is
liberated allowing the slide piece and projecting lump to fall below and clear of the
finger and the stop rod makes a part revolution allowing the trap lever rod to fall and
thus the rollers are stopped when the machine has been in motion a short time, and
the slack has been taken up.
set on
"
When the machine is "thrown off" the slide piece and projecting lump are raised
by the hand wheel and chain until the finger is raised and the stop rod receives a
slight turn the trap lever rod being raised, and by this movement the parts and trap
levers are operated so that the trap levers and threads guides are always in the correct
working position.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying sheets of
drawings in which :-
Fig. 1 is an end elevation of a part of a doubling or twisting frame with our
improvements applied thereto.
Fig. 2 is a front elevation of Fig. 1.
Figs. 3 and 4 are details of our invention.
According to this our said invention the object is to secure by automatic appliances
brought into operation through the use of the ordinary agency for stopping or
starting the frame that all the trap levers and thread guides carried by the latter
shall be down or in their correct working position and the making of hard twist be
voided.

page_text: From the tin cylinder 1 or other going part of the frame we drive by means of a
tape or band 2 a pulley 3 on a short horizontal shaft on which is the pinion 4 gear-
ing with and driving the wheel 5 also on a short horizontal shaft on which is a worm 6
gearing with and driving the worm wheel 7 on the shaft 8 the latter being secured to
the frame 9 by brackets or otherwise, and on the shaft 8 is a ratchet wheel 10. Fixed
to the frame 9 is a bracket or bed plate 11 in which is carried the slide piece 12 fixed
thereon being the projection or cam surface 13, passing through the slide piece 12 and
through a longitudinal vertical slot, in the bed plate 11 is the catch 14 held in position
by the spring 15, this catch 14 engages with the teeth in the ratchet wheel 10.
Attached to the projection or cam surface 13 is the chain 16 working over the guide
pulley 17 fixed to the bed plate 11, the other end of the chain 16 is attached to the
collar 18 on the threaded shaft 19 which when turned by the hand wheel 20 moves
the collar along the threaded shaft 19 the collar 18 being held in position by the
slotted bracket 21 the slide piece 12 and projection 13 can thus be "wound up
or raised by the chain 16 and wheel 20. On the stop rod 22 which extends
across the frame is a finger 23 which when the slide piece 12 is "wound up
in the raised position, rest on the projection or cam surface 13, to each end of
the stop rod 22 is attached by fingers 24, 24 the trap lever rods 25, 25 on which the
trap levers 26 rest.
The action is as follows.
"
or
When the frame is "set on" the slide piece 12 and projection 13 are in the raised
position the finger 23 resting on the latter, and the catch 14 engages with one of the
teeth in the ratchet wheel 10 and the stop rod 22 fingers 24. 24. are in the position
shewn by Fig. 3. but when the ratchet wheel has made a part revolution the catch 14
is liberated allowing the slide piece 12 and projection to fall below, and clear of the
finger 23 and the latter, and the stop rod 22 and fingers 24. 24 also fall slightly so that
the trap lever rod allows the trap lever 26 to fall and prevents any further movement
of the trap rollers. The ratchet wheel 10 and its connection with the tin cylinder 1
or other going part are such that between the " setting on of the frame and when
the catch 14 is liberated the "slack" has been taken up and consequently "hard twist"
or faulty yarn is avoided when the frame is "thrown off" the slide piece 12 and
projection 13 are raised by turning the hand wheel 20 until the finger 23 rests on the
projection and the catch 14 engages with the ratch wheel 10 and the trap lever
rod 25 is slightly raised, the hand wheel 20 is then turned back to leave the chain 16
slack so that the projection 13 and slide piece 12 can fall when necessary and thus
the trap levers, and thread guides are in the correct working position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The construction, combination and arrangement of parts for the purpose herein fully
described and illustrated by the annexed drawings.
Dated this 9th day of July 1889.
