We, JOHN DAWSon, Alfred Shuttleworth, and JOHN KNIGHT, all of Charnley
Mill, Whitefield, near Manchester, in the County of Lancaster, Picker Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the leather pickers used in what
are known as "underpick" looms for weaving.
These pickers are usually made from a long single piece or strip of leather
which is coiled or doubled twice round to obtain the shape and thickness required
filling piece being used at one or both ends, the result being that there is always
a lap joint at one end which is objectionable.
a
Another defect is that the sides are liable to become bulged outwards by the
action of the picking lever and to become broken.
According to our invention we form the picker from two shorter pieces of
leather which are brought double along one side then bent in a loop round the
face and carried back along the other side the ends being parallel to each other
at the rear of the shuttle where they are kept apart by means of a filling piece.
A second filling piece (which also forms the foot of the shuttle) is put inside
the forward loop and thus forms a firm solid front without joint.
To prevent the liability to bulge and break we place a strip of sheet metal,
rather narrower than the leather, on each side, and we rivet the whole together
by two rivets at each end.
In some cases we use a single strip of metal sufficiently long to pass along
both sides and round the rear end, and if preferred, it may also be carried round
the face of the picker, but in that case a hole must be punched or formed
through the metal to allow the leather face to strike against the point of the
shuttle.

[Price 8d.]

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:―
This invention relates to improvements in the leather pickers used in what
are known as "underpick" looms for weaving, and the manner in which our
said invention 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 drawings is a plan view, and Fig. 2 a side elevation, and Fig. 3
a face view of one of the ordinary leather pickers as hitherto made and used
for underpick" looms.

These pickers are usually made from a long single piece or strip of leather a
which (as seen at Fig. 1) is coiled or doubled twice round to obtain the shape
and thickness required, a filling piece 6 being used at one, or both ends, the result
being that there is always a lap joint at one end (as shown at c Figs. 1 and 3)
which is objectionable, especially when at the face" end.
Another defect is that the sides are liable to become bulged outwards by the
action of the picking lever and to become broken.
According to our invention we form the improved picker (see plan view
Fig. 4, side elevation Fig. 5, and face view Fig. 6) from two shorter pieces of
leather e and f which are brought double along one side, then bent in a loop
round the face end (see Figs. 4 and 6) and carried back along the other side,
the ends being parallel to each other at the rear end of the shuttle, where they
are kept apart by means of a filling piece g. A second filling piece h, which
also forms the foot of the picker is put inside the forward loop and thus forms
a solid front without joint (see Fig. 6). They may be fastened with either
staples or rivets.
To prevent the liability of the picking lever to bulge and break the leather
sides we place a strip or piece of metal i (see Fig. 7) preferably inside, as seen
at Fig. 4 and 5, such piece of metal being provided with a spur k at one end by
which it may be rivetted to the pieces of leather e, f, forming the sides.
Or in some cases we may use a single strip of metal sufficiently long to pass
along both sides and round the 'rear end, and if preferred it may also be carried
round the face of the picker, but in that case a hole must be punched or formed
through the metal.
We also, in some cases, propose (instead of forming the body of the picker
of two strips of leather as above described) to form the same of a single strip
of leather twice the width and doubled lengthwise (as shown in plan view
Fig. 8 and rear view Fig. 9).
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
:-
">
1. The improvements in the manufacture of leather pickers for "underpick
looms consisting in forming said pickers without a lap joint at the face sub-
stantially as herein before described and illustrated by Figs. 4, 5, 6, 8 and 9 in
the drawings annexed.
2. Fitting to leather pickers for underpick looms a metal strip formed with a
spur as in Fig. 7, substantially as and for the purpose herein before described.
