STOPPING MOTION FOR WARPING OR BEAMING MACHINES.'
"
Sealed the 12th May 1874, and dated the 20th November 1873.
PROVISIONAL SPECIFICATION left by the said James Walmsley at
the Office of the Commissioners.of Patents, with his Petition, on
the 20th November 1873.
I, JAMES WALMSLEY, of Preston, in the County of Lancaster,
Mechanic, do hereby declare the nature of the said Invention for
"AN IMPROVED SELF-STOPPING MOTION FOR WARPING OR BEAMING MACHINES," to
be as follows :-
I form the front expanding comb of the machine with the dents bent
over in such a manner that they may not only form guides for the warp,
but also that each dent may carry at or near its end a small hook,
oeillet, or staple, which shall rest on a thread of the warp and be
capable of rising and falling. Near the bottom ends of the said hooks,

page_text: oeillets, or staples is placed a vibrating bar carried from a shaft by arms;
a lever on one end of the same shaft carries a catch which rests in a
notch in the end of an independent vibrating lever. The said vibrating
lever receives motion from a cam on the drum shaft, and pressing
against the catch before-named imparts motion to the vibrating bar
through the before-named catch, lever, shaft and arms, a spring
working in connection therewith. Each thread of the warp is passed
between two dents of the expanding comb and through one of the
before-named hooks, oeillets, or staples. The said warp may either pass
first between the dents or first through the said hooks, oeillets, or
staples, it next passes over a carrier roller to the warp beam. If a
thread of the warp should break, its hook, oeillet, or staple immediately
falls down, and the lower end of it prevents the vibrating bar from
moving to the extent of its motion. This has the effect of drawing the
catch from off the notch in the vibrating lever. As the said lever recedes
the catch then falls down, and as the vibrating lever advances it presses
the said catch against the knocking-off handle and pushes the said
handle out of its notch. The said handle then moves forward and stops
the machine, and at the same time by means of an incline lifts and
replaces the catch in the notch of the vibrating lever; it also lifts or
causes to be lifted by means of two inclines a bar running below the
hooks, oeillets, or staples, and which raises up to the working level any
hook, oeillet, or staple that may have fallen.

SPÈCIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Walmsley in the Great Seal Patent Office 2
on the 15th May 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WALMSLEY, of Preston, in the County of Lancaster, Mechanic, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 3
Letters Patent, bearing date the Twentieth day of November, in the year
of our Lord One- thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself; Her heirs and suc-
cessors, give and grant unto me, the said James Walmsley, Her special
license that I, the said James Walmsley, my executors, administrators, 3

page_text: and assigns, or such others as I, the said James Walmsley, iny
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
SELF-STOPPING MOTION FOR WARPING OR BEAMING MACHINES," upon the
condition (amongst others) that I, the said James Walmsley, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
:
NOW KNOW YE, that I, the said James Walmsley, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying Sheet
of Drawings:-
I form the front expanding comb A of the machine with the dents B'
bent over in such a manner that they may not only form guides for the
warp c, but also that each dent may carry or guide at or near its end a
small hook, oeillet, or staple D resting on a thread of the warp and
capable of rising and falling. Near the bottom ends of the said hooks,
oeillets, or staples I place a vibrating bar E and carry the same from a
shaft F by arms G; on one end of the same shaft I place a lever H
serving to carry a catch K, which when the machine is working rests in
a notch in the end of an independent vibrating lever L. The said
vibrating lever receives motion from a cam M on the drum shaft, and
imparts motion to the vibrating bar E by pressing against the catch K and
causing the said bar to move backward, the spring N serving to cause it
to move forward. Each thread of the warp passes through a hook,
ocillet, or staple, and between two of the dents of the expanding comb,
`or it may pass first through the comb and then through the hook, oeillet,
or staple; it next passes over the carrier roller P to the warp beam Q.
When a thread of the warp breaks its hook, oeillet, or 'staple falls down
to the position shewn in Fig. 4, and at R, Fig. 2, and the lower end of it
prevents the vibrating bar E being moved to the full extent of its motion

page_text: by the spring N, and this has the effect of preventing the catch K from
following the vibrating lever L, which lever continuing to recede slides
from under the said catch and allows it to fall down; the vibrating lever
then in coming forward presses the said catch against the knocking-off
spring S and forces the said spring out of its notch, which spring then
moves forward and stops the machine in the usual manner. Besides
stopping the machine the said spring in moving forward brings a pin T
into contact with the inclined part of the catch K, and lifts the said
catch into its working position in the notch of the lever L, at the same
time the said spring by actuating the two upright shafts U, U, moves
the fingers V, V, along the two inclines W, W, and lifts the bar X to the
position shewn at Z, Fig. 2, and so elevates to the working level any
hook, oeillet, or staple that has fallen.

In witness whereof, I, the said James Walmsley, have hereunto
set my hand and seal, this Thirteenth day of May, in the year
of our Lord One thousand eight hundred and seventy-four.-
