Improvements in Pickers for Looms.
FREDERICK GREENWOOD, Trafalgar Works of Rochdale in the County of
Lancaster Doffing Plate and Spring Maker and JAMES CLARK 123 Durham Street
of Rochdale in the County of Lancaster Strap Maker do hereby declare the nature
of this invention to be as follows:-
Our invention relates to pickers for looms and consists firstly, in an arrangement
protecting the picker against the action of the picking stick, and provides a band
of metallic substance to strengthen the picker throughout. It also provides that
all parts of the picker subject to wear from the action of the picking stick or shuttle
can be replaced and renewed as required.
According to one part of our invention we form by a band of steel or iron
whether fluted, corrugated, or plain, or by a band or bands of wire or other
metallic substance, whether in strips, rods or threads woven together or separate,
we form a box or outer covering to layers of leather, buffalo, india rubber,
vulcanite or suitable substance, into which the end of the picking stick is placed.
One end of the picker is encircled with the above metallic band or bands, forming
a box or cavity into which pieces of single or compressed leather, buffalo, india
rubber, vulcanite or suitable springs may be placed into, to form a driver or buffer
to propell and resist the shuttle in its action across the loom. The improvement
provides that this box shall have a removable lid or covering to admit of the single
or compressed pieces of leather, buffalo, india rubber, vulcanite, paper, or springs
being replaced or renewed as required.
The layers of leather and etc. which are placed inside the metallic band or bands
may be renewed as required.
Our invention further provides that by placeing a band of metallic substance
inside a leather or buffalo casing, whether encircled at the outside with steel, iron,
or other metal, the object being to protect the leather or buffalo against the action
& wear of the picking stick.

COMPLETE SPECIFICATION.
Improvements in Pickers for Looms.
We, FREDERICK GREENWOOD, Trafalgar Works, Rochdale, County of
Lancaster, Doffing Plate and Spring Maker, and JAMES CLARK 123 Durham
Street Rochdale County of Lancaster, Strap Maker, 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 :-
Our invention relates to pickers for looms and consists firstly in arrangements
protecting the picker against the action of the picking stick rod (in its tendency to
break the said picker) by means of a hand or outer covering encircling an inner
wearing surface. It also provides that all parts of the picker subject to wear from
the action of the picking stick rod, or the shuttle tip, can be replaced and renewed
as required.
Our invention relates to pickers as used in looms for weaving. This picker carries
the momentum or force given by the picking stick rod A (Fig. 1) to the shuttle
at the point D (Fig. 1). By this force or momentum the shuttle or shuttles are

page_text: driven across the loom, the picker B (Fig. 1) being the intermediary betwixt the
picking stick rod and the shuttle.
The picking stick rod A. (Fig. 1). being inserted into the picker B (Fig. 1).
acting from K (Fig. 1) carries the picker across the loom. as C (Fig. 1).
According to one point of our invention we form by a band which may be of
steel, iron, brass, vulcanite or other suitable material, which may be corrugated,
fluted or plain, or by a band or bands of wire, whether in strips, rods or threads
joined together so as to form an outer covering or protection, complete or in part,
to layers of leather, india-rubber, buffalo hide, paper, vulcanite or other suitable
material as in F (Fig. 2) which layers are placed inside the outer band. forming a
space or slot G (Fig. 2), the picking stick rod being, inserted therein when in
work.
A further part of our invention consists of a cavity or box formed at one end of
the band at H (Fig. 2); this box may be attached to the band E (Fig. 2), or it
may be made of the two sides of the band E (Fig. 2) with a back support.
(Fig. 2) and a top and bottom so as to form a box as per sketch H (Fig. 2). This
box arrangement may be used at each end forming a picker as (Fig. 6) having
each end prepared to act directly in turn against the shuttle.
Inside the box may
be placed strips or blocks of buffalo hide, leather, india-rubber, paper, vulcanite or
springs, or other suitable substance so as to form a driver or buffer to propell and
resist the shuttle in its passage across the loom. This box may be made so that
the lid or covering may be adjustable and removable with suitable fastenings. The
buffer inside the box may be secured in position by a spring attachment, revitted,
or by any other suitable arrangement. The driving face of this buffer is counter-
sunk as (D' Fig. 3 & 4) this being the point of contact with the shuttle. The face
of the buffer and picker may be as Fig. 3 or as Fig. 4.
A further part of our invention consists of placing a metallic substance inside a
band of leather or buffalo hide casing, which may or may not be encircled with
another metallic band as the picking stick rod A working in slot G Fig. 5
against the metallic substance E Fig. 5, the object being to protect the leather or
buffalo hide against the action and wear from picking stick, rod A.
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
For use in looms in weaving, the herein before described arrangement, for driving
the shuttle across the loom by means of a picker (B Fig. 1) having a protecting
band (E Fig. 2, 5, 6) and buffer (D Fig. 1) and driver (F Fig. 2) removable.
from other portions of the picker.
Dated this Second day of June 1893.
