IMPROVEMENTS IN THE CONSTRUCTION OF PICKERS EMPLOYED IN LOOMS FOR WEAVING
Year: 1881

page_text: LETTERS PATENT to Edward Hollingworth, Manager in the Firm of
Hutchinson, Hollingworth, and Co., Limited, of Dobcross, in the County of
York, Woollen Loom Makers, for an Invention of "IMPROVEMENTS IN THE
PROVISIONAL SPECIFICATION left by the said Edward Hollingworth at
the Office of the Commissioners of Patents on the 24th December 1881.
EDWARD HOLLINGWORTH, Manager in the Firm of Hutchinson Hollingworth
and Co. Limited of Dobcross in the County of York, Woollen Loon Makers.
"IMPROVEMENTS IN THE CONSTRUCTION OF PICKERS EMPLOYED IN LOOMS FOR
WEAVING."
This Invention has reference to pickers employed in woollen and other heavy
looms. As at present constructed they are made with a vertical pin or stud to
receive one end of the leather picking arm, the other end of the leather picking
arm being connected to the picking stick which is also vertical, consequently the
leather arm was always partially twisted, and at each stroke thereof much wear
and tear took place.
The two picker spindles in the shuttle boxes were also placed one behind the
other and the holes formed in the picker were also made one behind the other to
suit the spindles. This method of constructing and mounting the pickers is
objectionable because the distance between that part of the picker struck by the
shuttle and the second picker spindle was sufficient to allow leverage and cause
unsteady working.
My Invention consists in making the pin or stud which receives the leather arm
to be horizontal, by which means the leather is not twisted, between the picker
and picking stick consequently wear and tear of the leather is greatly reduced,
and I also place the picker spindles one above the other and make holes in the
picker to suit, so that the length of leverage is reduced and steadier working
obtained.
In order to reduce the concussion which takes place every time the shuttlo
strikes the picker, I form a cushion behind the india-rubber, buffalo hide or other
material which may be employed by placing in the recess containing the such
material a spiral spring cork or other yielding substance.

"
This Invention has reference to pickers employed in woollen and other heavy
looms. As at present constructed they are made with a vertical pin or stud to
receive one end of the leather picking arm, the other end of the leather picking
arın being connected to the picking stick which is also vertical consequently the
leather arm was always partially twisted and at each stroke thereof much wear
and tear took place.
The two picker spindles in the shuttle boxes were also placed one behind the
other, and the holes formed in the picker were also made one behind the other
to suit the spindles. This method of constructing and mounting the picker is
objectionable because the distance between that part of the picker struck by the
_shuttle_and_the_second_picker_spindle_was sufficient to allow leverage.and.cause
unsteady working.
My Invention consists in making the pin or stud which receives the leather arm
to be horizontal, by which means the leather is not twisted, between the picker
and picking stick consequently wear and tear of the leather is greatly reduced,
and I also place the picker spindles one above the other and make holes in the
picker to suit so that the length of leverage is reduced and steadier working
obtained.
In order that my Invention may be better understood I herein give reference to
the accompanying Sheet of Drawings illustrative thereof wherein Fig. 1 is an end
view of a metal picker constructed according to my Invention and Fig. 2 is a plan
of same.
A is the body of the picker and B the hollow part for the insertion of
india-rubber or other suitable material for striking the shuttle. C and D are the
picker spindles placed one above the other and on which the picker slides as it is
sent backward and forward by the picking stick as will be well understood. E is
the horizontal pin or stud for receiving one end of the leather picking arm F and
which is prevented from slipping off the end by the lock nuts G. It will be
understood by those conversant with pickers employed in the heavy woollen trade
that the use of the horizontal pin or stud is much better adapted for the purpose
than an upright pin, as the leather picking arm is not twisted but is perfectly
straight whereby wear and tear of leather is considerably reduced, it will also be
seen that by arranging the picker spindles one above the other, the picker is less
and more compact, consequently steadier in its action and by its length being
shortened the leverage is reduced.
Fig. 5 shews another arrangement of picker.
Fig. 3 is an end view and Fig. 4 is a plan view of the same construction of
picker composed of buffalo hide, except the horizontal pin or stud E which is
wrought iron.
Having now described the nature of my said Invention and shewn with the
aid of Drawings how the same may be carried into practice I would have it
understood that I do not limit myself to the precise details or configuration of the
parts I have described and shewn, as the same may be varied or modified without

page_text: departing from the nature of my said Invention but what I do claim and desire to
be secured is-
The construction of pickers such as are herein shewn and described working
upon picking spindles are arranged one above the other in combination with the
5 horizontal pin or stud E.
In witness whereof I the said Edward Hollingworth have hereunto set my
hand and seal this Twentieth day of June in the year of our Lord One.
