India Rubber Merchant and Mill Furnisher, for an Invention of "IMPROVE-
PROVISIONAL SPECIFICATION left by the said Elliott Hallas at the Office
of the Commissioners of Patents on the 14th November 1881.
ELLIOTT HALLAS, of Huddersfield, in the County of York, India Rubber Merchant
and Mill Furnisher. 1MPROVEMENTS IN PICKERS EMPLOYED IN LOOMS FOR
WEAVING."
"
This Invention has reference to pickers employed in looms for weaving woollen
and other heavy goods. The pickers at present employed have a round hole formed
in then, in which is driven a piece of india rubber for the purpose of striking the
shuttle and for the shuttle to bound against when it is driven home. In practice
it is found that the india rubber in the picker is not always brought into contact
with the point of the shuttle, but is frequently struck with the flange of the picker,
doing damage to both shuttle and picker. Another disadvantage being that in
consequence of the india rubber being so small in diameter, the point of the shuttle
has a tendency to strike so very often in one place that the rubber is soon
damaged and rendered worthless.
To remedy these defects is the object of my Invention, which I accomplish by
making the hole in the picker for the reception of the india rubber of an oval
form and placed in a vertical position in the picker, by which means the shuttle
has more surface to strike against and the danger of striking the flange is rendered
impossible.
Instead of the opening in the picker being made oval it may be made round,
but larger in diameter, and so placed that the increased size of opening is brought
higher than the picking rod and not below it.
The opening is increased from one inch diameter and upwards, and is made bell
mouthed, so that the rubber has room to expand at the part which comes into
contact with the shuttle.

by the said Elliott Hallas in the Great Seal Patent Office on the 13th May

ELLIOT HALLAS, of Huddersfield, in the County of York, India Rubber Merchant
and Mill Furnisher. "IMPROVEMENTS IN PICKERS EMPLOYED IN LOOMS FOR
WEAVING."
This Invention has reference to pickers employed in looms for weaving woollen
and other heavy goods. The pickers at present employed have a round hole
formed in them in which is placed a piece of india rubber for the shuttle to bound
against when it is driven home. In practice it is found that the picker does not
always strike against the india rubber, the point of the shuttle frequently striking
against the metal flange of the picker, doing damage to both shuttle and picker.
Another disadvantage is, that in consequence of the india rubber being so small in
diameter, the part of the shuttle has a tendency to strike so very often in one
place that the rubber is soon damaged and rendered worthless.
To remedy these defects is the object of my Invention, which I accomplish by
making the hole in the picker for the reception of the india rubber of an oval form
and placed in a vertical position in the picker, by which means the shuttle has
more surface to strike against and the danger of striking the flange is rendered
impossible.
"
Instead of the opening in the picker being made oval it may be made round, but
larger in diameter, and so placed that the increased size of opening is brought
higher than the picking spindle_and_not_below-it.-
The opening is increased from one inch diameter and upwards, and is made bell
mouthed, so that the rubber has room to expand at the part which comes into
contact with the shuttle.
In order that this Invention may be more fully understood, I herein give reference
to the accompanying Sheet of Drawings, wherein Figure 1 is end elevation of my
improved picker shewing the oval opening A for the insertion of india rubber or
other suitable material, and Figure 2 is a perspective elevation of my improved
picker, shewing a round opening B of considerably larger diameter than is at present
made for the insertion of india rubber. It will be understood that the increased
size of opening is taken above the picking spindles C and D, and not below.
By the use of pickers, as herein shewn and described, when the checking
surface is increased in diameter, the shuttle is more certain of being kicked, and
the drawing of the staples and throwing of the shuttle is prevented. Although
more india rubber is required to fill up the increased size of opening made in
the picker, the use thereof has been found a considerable saving; and as the metal
flanges do not get knocked by the shuttle, the picker is far more durable than the
present construction of picker.
Having now described my Invention and shewn how it may be carried into
practice, I would have it understood that what I claim is,
Firstly. The use and employment of the oval opening A, as shewn in Figure 1,
for the purpose of substantially as described.
Secondly. The use and employment of the round opening B, as shewn in Figure 2,
when such round opening is more than one inch and one sixteenth in diameter for
the purpose substantially as described.
In witness whereof, I, the said Elliot Hallas, have hereunto set my hand
and seal, this
day of May, in the year of our Lord One thousand
eight hundred and eighty two.
