IMPROVEMENTS IN 'PICKERS' EMPLOYED IN LOOMS FOR WEAVING
Year: 1879

page_text: LETTERS PATENT to George Harling, of Lockwood, near Huddersfield, in the
County of York, Machinery Agent, for the Invention of "IMPROVEMENTS IN
'PICKERS' EMPLOYED IN LOOMS FOR WEAVING."
Sealed the 2nd March 1880, and dated the 6th September 1879.
PROVISIONAL SPECIFICATION left by the said George Harling at the Office
of the Commissioners of Patents on the 6th September 1879.
GEORGE HARLING, of Lockwood, near Huddersfield, in the County of, York,
Machinery Agent. "IMPROVEMENTS IN PICKERS' EMPLOYED IN LOOMS FOR
WEAVING."
This Invention relates to pickers for use in woollen looms, which pickers are
composed of iron, the head thereof being hollow for the reception of india-rubber.
It has heretofore been customary to take a piece of findia-rubber of the same
length as the hollow head into which the india-rubber bas been forced, the only
provision for retaining the same within the head being a. ring or enlargement in
the interior of the head. This ring has been insufficient for the purpose, as in a
short time the india-rubber has been driven out by the shuttle and rendered
useless.
My Invention is for the purpose of reducing this consumption of india-rubber by
forming the head of the picker in such a manner that a smaller quantity of india-
rubber is required to form the cushion, and this when properly inserted cannot be
displaced by the shuttle.
.
The accompanying sketch represents a sectional view of a "picker-head" in which
are two concave chambers a communicating by a small hole in the middle of the
picker. In these chambers are inserted the cylindrical pieces of india-rubber b,
which are somewhat shorter than the chambers, so that when struck by the shuttle
tip c, the india-rubber not being rigidly supported at the back, is capable of yielding
to the blow, and the shuttle tip does not cut it up so quickly as it would do if the
rubber filled the chamber entirely.
The internal diameter of the picker being larger than the orifice the rubber can
only be forced out by pressure from behind, and cannot possibly be lost whilst the
loom is at work.
By my Invention the rubber cushion lasts considerably longer than in the
ordinary picker, and is only about one third the size hitherto necessary.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said George Harling in the Great Seal Patent Office on the 5th March

"IMPROVEMENTS IN PICKERS' EMPLOYED IN LOOMS FOR
WEAVING."
This Invention relates to pickers for use in woollen looms, which pickers are
composed of iron, the head thereof being hollow for the reception of india-rubber.
It has heretofore been customary to take a piece of india-rubber of the same length
as the hollow head, into which the said india-rubber has been forced, the only
provision for retaining the same within the head being a ring or enlargement in
the interior of the head. This ring has been insufficient for the purpose, as in a
short time the india-rubber has been driven out by contact with the shuttle and
rendered useless.
My Invention is for the purpose of reducing this consumption of india-rubber by
forming the head of the picker in such a manner that a smaller quantity of india-
rubber is required to form the cushion, and this, when properly inserted, cannot be
displaced by the shuttle. The accompanying sketch represents in Fig. 1 a sectional
view of a "picker head," a side elevation of which is shewn in Fig. 2. In the
picker head are two concave chambers a communicating by a small hole in the
the middle of the picker. In these chambers are inserted the cylindrical pieces of
tindia-rubber b, which are somewhat shorter than the chambers, so that when struck
by the shuttle tip c, the india-rubber, not being, rigidly supported at the back, is
capable of yielding, to the blow, and the shuttle tip does not cut it so quickly as it
would do if the rubber filled the chamber entirely. The internal diameter of the
picker being larger than the orifice the rubber can only be forced out by pressure
from behind, and cannot possibly be lost whilst the loom is at work.
By my Invention the rubber cushion lasts considerably longer than in the
ordinary picker, and is only about one third the size hitherto necessary.
Having thus described the nature of my Invention, and shewn by Drawings
how, the same is to be performed, I would have it understood that I claim as my
Invention,-
Firstly. The construction of pickers having two chambers a separated by an
'internal ring or diaphram so as to prevent the india-rubber cushion from being
forced from one chamber into the next, in manner substantially as herein shewn
and described.
>
Secondly. The construction of pickers; in which the chambers a are constructed
at the orifice so as to retain the india-rubber firmly when it has been inserted, in
manner substantially as herein shewn and described.
In witness whereof, I, the said George Harling, have hereunto set my hand
and seal, this Second day of March, in the year of our Lord One thousand
eight hundred and eighty.
