PROVISIONAL SPECIFICATION.
An Improved Measuring and Stop Motion for Looms.
We JAMES HENRY STOTT of 28 Lodge Street Middleton near Manchester in
the County of Lancaster Weaving Manager, and JOSEPH BRIDGE, ALFRED
BRIDGE and ARTHUR BRIDGE, trading as The Wilton Manufacturing Company,
of Townley Street Middleton aforesaid Manufacturers do hereby declare the nature
of this invention to be as follows:-
The object of this invention is to provide a loom with a simple and positive
arrangement of mechanism for measuring the length of cloth as it is produced
and for stopping the action of the loom as soon as any desired definite length has
been woven.
For the purposes of this invention we fix on one end of the axle of the emery.
or sand-covered taking-up roller of the loom a spur wheel which by means of a
train of change wheels drives a shaft or axle supported on a bracket bolted to the
loom side, or the said train may be driven from the ordinary taking-up wheel which
drives the sand roller.
On one end of this shaft or axle is keyed a worm driving a flanged worm wheel.
This worm wheel is provided with a spring stud or pin which as the worm
wheel revolves comes in contact with a hook or catch and causes it to liberate
a lever.
This lever is mounted in a vertical position at or near one end of a shaft which
extends across the loom and is provided with a similar vertical lever at the other
end, which is in connection with the weft fork lever which works against the
setting-on rod.
To the same shaft is also connected a horizontal lever which is held down by
a coiled spring.
As soon as the required length of cloth has been woven the spring pin in the
worm wheel comes against the catch liberating the first mentioned vertical catch
lever, and the coiled spring, being thus set free, pulls down the horizontal lever to
which it is attached when the second named vertical lever acts against the weft
fork lever and thus releases the setting-on rod from its notch and stops the loom.
When the weaver wishes to re-start the loom he (or she) must draw back the
spring pin free from the catch, which will then fall back by its own weight into
the former position and hold the catch lever ready for the next length.
The length woven at a time is regulated by making the requisite change in the
train of wheels above mentioned.

COMPLETE SPECIFICATION.
An Improved Measuring and Stop Motion for Looms.
We JAMES HENRY STOTT of 28 Lodge Street Middleton near Manchester in
the County of Lancaster, Weaving Manager, and JOSEPH BRIDGE, ALFRED
BRIDGE and ARTHUR BRIDGE trading as The Wilton Manufacturing Company
of Townley Street Middleton, aforesaid, Manufacturers, 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 :-
The object of this invention is to provide a loom with a simple and positive

page_text: arrangement of mechanism for measuring the length of cloth as it is produced, and
for stopping the action of the loom as soon as any desired definite length has
been woven.
The nature of my invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the sheet
of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawing is a front elevation of so much of a power loom as is
necessary to illustrate the application of my invention thereto, and Fig. 2 is a plan
-view of the same.
Fig. 3 is a vertical section taken through about the line A-B and Fig. 4 is a
. similar section taken through about the line C-D.
a is part of the framing of the loom the breast beam and c the ordinary emery
or sand-covered taking-up roller.
For the purposes of my invention I fix upon one end of the axle of the roller c
a spur wheel d which, by means of a train of change wheels e drives a short shaft
or axle supported on a bracket bolted to the loom side, or the said train
of wheels e may be driven from the ordinary taking up wheel which drives the said
.roller c.
On one end of the shaft or axle is keyed a worm / driving a flanged worm
'wheel i.
This worm wheel i is provided with a spring stud or pink which as the worm
wheel revolves comes into contact with a hook or catch thereby raising the catch
lever m and liberating the bent lever n (see Figs. 1 and 3) which is keyed at or
near one end of a shaft o which extends across the loom and is provided with a
lever P at the other end which is made with a stop 7 which works against the weft
fork lever (see also Fig. 4). To the same shaft o also at this end is connected
a second lever s bent downwards, and acted upon by a coiled spring t.
7°
As soon as the required length of cloth has been woven the spring pin & in the
worm wheel i comes against the catch or hook lifting the catch lever m, and the
coiled spring t at the other end being thus set free pulls the bent levers to which
it is attached and causes the lever p with its stop q to act against the weft fork
lever and thus releases the setting-on-rod u from its notch and stops the loom.
The spring pink can then be withdrawn from the catch lever and the weaving
can proceed without turning the wheel i backwards.
r
'It will be seen on referring to Figs. 2 and 3 that the worm wheel i is shown as
provided with a second spring pin or stud k¹ on the other side acting on a second
hook or catch also attached to the catch lever m. This may be adopted when
required so that one spring pin can be used for the body of the cloth and the
other for the heading, or if required more than two spring pins and catch levers
may be used.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The construction and application to a power loom of an apparatus substantially
as hereinbefore described and illustrated by the drawings annexed for measuring
the length of cloth and heading as it is produced, and automatically stopping the
.action of the loom as soon as any desired definite length has been woven.
