PROVISIONAL SPECIFICATION.
Improvements in or relating to the Picking Motion of Looms for
Weaving.
We, GEORGE HARRY ASHWORTH of the firm of Henry Ashworth. and Sons, of
New Eagley Mills, Turton near Bolton, Manufacturers, and HENRY NOBLETT of
8 Bank Top, Sharples near Bolton, Manager, both in the County of Lancaster,
do hereby declare the nature of our said invention to be as follows:-
This invention refers to improvements in or relating to the picking motion in
what are known as over-picked looms, and is designed to dispense with the ordinary
buffer, buffer strap, and securing bolt; reduce strain on picking stick, picking
band, and picker to prevent or minimise breakages; also to facilitate cleaning of
shuttle-box, and to partly obviate oil being thrown on the cloth during the
operation of weaving. This we effect by mounting on the framework of the loom;
in close proximity to the picking shaft, a fixing or its equivalent carrying an
adjustable centre or pin to which is attached a check strap; the said adjustment
being for the purpose of maintaining an uniform stretch or tension on the latter.
The other end of the check strap is secured to a quadrant on the metallic head
employed for securing the picking stick to the picking shaft or otherwise.
Immediately the shuttle is operated to be thrown through the "shed "the picking
stick is arrested by the check strap. encircling and gripping the face of the afore-
said quadrant, thereby minimising or reducing the strain on the picker and picking
stick. In lieu of the expensive leather buffers at present employed our invention
'allows of the same being replaced with any light or pliable yielding-material
mounted loosely on the picker spindle.

...
We, GEORGE Harry Ashworth of the firm of Henry Ashworth and Sons of
New Eagley Mills, Turton near Bolton, Manufacturers, and 'HENRY NOBLETT of
8.Bank Top, Sharples near Bolton, Manager, both in the County of Lancaster, do
hereby declare the nature of our said 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 refers to improvements in or relating to the picking motion in
what are known as over-picked looms, and is designed to dispense with the ordinary
buffer, buffer strap, and securing bolt; reduce strain on picking stick, picking
band, and picker to prevent or minimise breakages; also to facilitate cleaning of
shuttle-box, and to partly obviate oil being thrown on the cloth during the
operation of weaving. This we effect by mounting on the framework of the loom,
in close proximity to the picking shaft, a fixing or its equivalent carrying
an adjustable centre or pin to which is attached a check strap; the said adjustment
being for the purpose of maintaining an uniform stretch or tension on the latter.
The other end of the check strap is secured to a quadrant on the metallic head
employed for securing the picking stick to the picking shaft or otherwise.
Immediately the shuttle is operated to be thrown through the "shed" the picking

page_text: stick is arrested by the check strap encircling and gripping the face of the afore-
said quadrant, thereby minimising or reducing the strain on the picker and picking
stick. In lieu of the expensive leather buffers at present employed our invention
allows of the same being replaced with any light or pliable yielding material
mounted on the picker spindle.
Fig. 1 is an elevation of so much of a picking motion employed in over-picked
looms as is necessary to illustrate our said invention.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a part elevation showing our invention when the picking bowl is being
operated by the cam on the cam shaft to throw the shuttle through the "shed,"
and
Fig. 4 is a plan of Fig. 3.
A is the picking shaft; B the picking bowl; C the loom side; I) the metallic
head; E the picking stick; F the cam, and G the ordinary cam shaft. To the
loom side C is secured the fixing H by the_bolt I or other equivalents. The
fixing H is provided with the slot or opening J in which is mounted the centre or
pin K by means of the nut L. To the centre or pin K is attached the check
strap M; the other end of the latter being secured to the quadrant or disc N by
the bolt O. The quadrant or disc N is mounted on the picking shaft A in any
convenient manner, being provided with the ordinary metallic head D prepared to
receive the picking stick E; the latter being secured by the nut P screwed on the
threaded end of the picking shaft A. When the picking bowl B is free from the
action of the cam F the picking stick E and the check strap M assume the position
shown in Figs. 1 and 2, wherein the check strap M is out of tension. Immediately
the picking bowl B has been operated upon or struck by the cam F to throw the
shuttle through the "shed" the picking stick E is arrested by the check strap M
encircling and gripping the face of the aforesaid quadrant or disc N as shown in
Figs. 3 and 4, thereby reducing the strain on the picker and picking stick E to a
minimum. The tension on the check strap M may be adjusted to a nicety by
altering the position of the centre or pin K in the slot or opening J in the
fixing H.
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 :-
In over-picked looms, the combination with the picking shaft A, of the quadrant
or disc N, check strap M, centre or pin K, and the slotted fixing H, applied and
operating substantially as described and as shown in the annexed drawings.
