Complete Specification Left, 24th Feb., 1890-Accepted, 29th Mar., 1890
PROVISIONAL SPECIFICATION.
Improvements in the Picking Mechanism of Power Looms.
We, CHARLES SUTCLIFFE BROOKE of Zetland Mills, Woollen Cloth Manufacturer,
and ELLIS BEAUMONT of Newsome Road, Weaving Overlooker, both of Huddersfield
in the County of York, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to re-place the picking strap hitherto employed in
under pick looms, which strap communicates motion from the picking lever to the
picking stick, by means of a substitute for the leather or hide strap, which substitute
hereinafter referred to as the "picking link" is more durable in its nature and not
so readily torn or broken out at the eyes or joints.
For this purpose we employ a metallic link, by preference a flat steel bar, having a
bole to receive a bolt formed near each end, and the bar twisted when hot so
that the flat side of one end is at a right angle to the rest of the bar, transversely.
The two ends of this picking link are secured to the picking lever and to the picking
stick respectively by means of loops of leather or hide held by bolts and nuts in the
ordinary manner.
Dated this Twenty-third day of May 1889.

COMPLETE SPECIFICATION.
Improvements in the Picking Mechanism of Power Looms.
We CHARLES SUTCLIFFE BROOKE of Zetland Mills, Woollen Cloth Manufacturer,
and ELLIE BEAUMONT of Newsome Road, Weaving Overlooker, both of Huddersfield
in the County of York, 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 :-
The object of this invention is to re-place the picking strap hitherto employed in
underpick looms, which strap communicates motion from the picking lever or crank
to the picking.arm or stick, by means of a substitute for the leather or hide strap,
which substitute hereinafter referred to as the "picking link" is more durable in its
nature and not so readily torn or broken out at the eyes or joints.
For this purpose we employ a metallic link, by preference a flat steel bar, having
a hole to receive a bolt formed near each end, and the bar is twisted when
hot so that the flat side of one end is at a right angle to the rest of the bar,
transversely.
The two ends of this picking link are secured to the picking lever or crank and to
the picking arm or stick respectively by means of loops of leather or hide held by
bolts and nuts in the ordinary manner, which loops are strengthened when necessary
by means of similarly formed loops of thin sheet or hoop steel.
In order to enable our invention to be fully understood we will proceed to describe
the same with reference to the accompanying drawings in which Figure 1 represents
a side view of our metallic picking link and Figure 2 represents the link secured to
the picking arm and to the stud of the picking lever or crank.
The metallic picking link is represented at A and is secured to the picking arm or
stick B by means of the loop of leather or hide C which is fixed to the link by the
bolt and nut D. The loop E at the other end of the link is secured by means of the
bolt and nut G, and passes round the stud F of the picking lever or crank H which
is actuated by the picking shaft J upon which it is fixed.

page_text: 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. In the picking mechanism of under pick power looms, in which the picking
arms are mounted in an approximately vertical position, the metallic picking link A,
formed by preference of a flat bar of steel, constructed and operating substantially
in the manner described and as represented in the accompanying drawings.
2. In the picking mechanism of under pick power looms the picking link A formed
of a flat bar of steel or other metal, and secured to loops of leather or hide C and E
by bolts and nuts D and G, the said loops being strengthened when necessary with
steel straps, by means of which loops the link is connected to the picking arm B
and to the picking lever or crank H for the purpose of actuating the picking
arm, substantially in the manner described and represented in the accompanying
drawings.
Dated this Twenty-first day of February 1890.
