PROVISIONAL SPECIFICATION.
Self Acting Positive Stop Motion for Sectional or other Warping
Frames or Machines.
JOHN LORD Manager in Cotton Mill 81 New Park Road Ordsall Salford
do hereby declare the nature of this invention to be as follows:-
My improvement is for the stopping sectional or other warping machines at any
desired length of pièce required, without the attendant being required to. bring
such machine to a standstill.
This is done by means of a cam or quadrant being fixed on the stud which
carries the measureing wheel by means of levers, which said levers operate upon
the wedge or lever thus liberating the friction bowl or roller from the friction
plate instantly.

COMPLETE SPECIFICATION.
Self Acting Positive Stop Motion for Sectional or other Warping
Frames or Machines.
I, JOHN LORD, of 81 New Park Road, Ordsall, Salford, 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 improvements in automatic stop motions for sectional
and other warping frames, the object being to stop the frame automatically when
any predetermined length of yarn has passed through such frame, and consists of
appliances simple and inexpensive of construction operated from the measuring
roller, so that when any predetermined length of yarn has passed over such roller,
the friction bowl or roller is withdrawn from contact with the friction plate, and
the frame immediately stops.
Such being the nature and object of my said invention, the following is a
complete description of same reference being had to the accompanying drawings
in which :-
Fig. 1 is a side elevation of the improved appliances for purpose aforesaid.
Fig. 2 is a front elevation partly in section of Fig. 1.
Fig. 3 is a plan view of part of Figs. 1 and 2.
According to this invention, the measuring wheels 1. 1 are driven from the
worm 2 on the axis of the measuring roller 3, and the said measuring wheels 1. 1
operate and are operated in the ordinary manner. On the axes or stud 4 which
carries the measuring wheel 1, is fixed a quadrant or cam 5, which, as the stud 4
revolves, comes in contact with the finger 6 fixed in one end of the lever 7, free to
turn on its fulcrum stud 8 in the bracket 9, fixed to the side frame 11 of the
machine. One end of the lever 7 is provided with a weight 12, and below this
weight 12 is a spring lever 13 bolted to the pedestal or bracket 14. To the spring
lever is bolted an adjustable block 15, which serves as a holding piece for the
weighted hand lever 17, the inner end resting under said block 15.
The action is as follows:-The measuring wheels are "set" in the ordinary
manner, and the stud 4 revolves until its cam 5 acting on the finger 6 depresses
one end of the lever 7, and the weight 12 is raised. When the cam 5 has cleared
the finger 6, the weight 12 falls, and coming into contact with the curved end 18
of the spring lever 13, the latter is moved so that the block 15 clears the top
[Price 8d.1

page_text: of the hand lever 17, and the weight 19 on the opposite end of the latter turns
the lever 17 on its fulcrum stud 20. The lever 17 passing through the hole 21
in the spring cotter 22, the latter is drawn up, whereby the block 24 carrying the
axle 25 of the friction bowl or runner 26 is allowed to move in its pedestal or
bracket 14, and the bowl or runner 26 moves clear of the friction plate 27, and the
frame is stopped.
The frame can be stopped by hand by depressing the hand lever 17 over-
coming the resistance of the spring lever 13 when the action is as hereinbefore
described.
To re-start the frame, the hand lever 17 is raised, and its free end being lowered,
comes in contact with the lower edge of the hole 21, consequently the spring
cotter 22 is forced downwards, and moves the friction bowl or runner 26 into
contact with the friction plate 27. The upward movement of the finger 6 is
limited by coming in contact with the cam 5.
Having now particularly described and ascertained the nature and object of my
said invention, and in what manner the same is to be performed, I declare that
what I claim is :-
(1.) The general construction, arrangement, and combination of parts constituting
the improved stop motion, as and for the purpose herein described, and as illus-
trated by the accompanying drawings.
(2.) The cam or quadrant 5, lever 7, weight 12, spring lever 13, holding
piece 15, weighted lever 17, and spring lever 22, all in combination as and for the
purpose herein described and substantially as illustrated by Figs. 1 and 2 of the
accompanying drawings.
