PROVISIONAL SPECIFICATION.
An Improved Shuttle Relief Motion for Looms.
We RICHARD HARGREAVES and EDWIN EDGE both of Vale Mill near Todmorden
in the County of York Cotton Manufacturers do hereby declare the nature of this
invention to be as follows :-
This invention consists of an improved motion for relieving the pressure of the
"swell" in the shuttle box of a loom, so as to release the shuttle just before
the picking motion comes into action.
For this purpose we weld or otherwise fix on the stop rod of the loom (which lies
under the shuttle race) a stud or projection, and to the crank arın we bolt or other-
wise fix a lever, and we so arrange the position of these two that just before the
picking motion comes into action the end of the lever attached to the crank arm
comes against the stud or projection on the stop rod thereby giving a portion of a
revolution thereto, and thus causing the usual fingers or levers connected to the
swells" in the shuttle box to relieve the pressure of the said "swells" and thus
release the shuttle just before it is struck by the picker.
"
The lever on the crank arm is adjustable so that it can be regulated in such a way
as always to act at the required moment.

COMPLETE SPECIFICATION.
An Improved Shuttle Relief Motion for Looms.
We RICHARD HARGREAVES and EDWIN EDGE both of Vale Mill near Todmorden
in the County of York Cotton 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 :-
This invention consists of an improved motion for relieving the pressure of the
"swell" in the shuttle box of a loom, so as to release the shuttle just before the
picking motion comes into action.
The nature of our said 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 annexed sheet of drawings marked with Figs. and letters of reference corre-
sponding with those in the following explanation thereof.
The drawing represents a section taken vertically through the "slay," and crank-
shaft of a loom showing the application of our invention thereto; Fig. 1. showing
the apparatus in the position it assumes when in its normal position with the shuttle
box swells" in action, and Fig. 2 showing the same at the moment when the
pressure of the "swells" on the shuttle is relieved.
a is the "slay," the "slay-sword," the crankshaft, and d the crank arm, e is
the "stop rod," the "stop-rod finger" and g the "swell."
For the purposes of our invention we weld rivet or otherwise fix on the stop rod e
of the loom (which lies under the shuttle race or slay b) a stud or projection and to
the crank armd we bolt or otherwise fix a lever i and we so arrange the position of
these two that just before the picking motion comes into action the end of the lever i
attached to the crank arm d comes against the stud or projection on the stop rod e
thereby giving a portion of a revolution thereto, and thus causing the usual fingers or
levers connected to the "swells g in the shuttle box, to relieve the pressure of the
33

page_text: said "swells" as shown at Fig. 2 and thus release the shuttle just before it is impelled
by the picker.
The lever on the crank arm d is adjustable so that it can be regulated in such
away as always to act at the required moment.
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 improved shuttle relief motion for looms consisting of the combination with
the "stop-rod-finger and "swell," of a stud or projection fixed on the "stop-rod"
and an adjustable lever fixed on the "crank-arm substantially as herein before
described and illustrated by the drawings annexed.
