Improvements in the Means or Method of Connecting the Pickers
the Picking Sticks of Looms for Weaving and in
Communicating Motion therefrom to such Pickers.
We, HEZEKIAH LISTER, and LOTON LISTER, of High Street, Great Horton, in the
County of York, Boot Manufacturers, FRANK CROSSLEY LISTER, of Halstead Place,
Great Horton aforesaid, Mechanic, and GEORGE THEWLIS, Prospect Place, Farsley,
in the said County Weaving Overlooker, do hereby declare the nature of this
invention to be as follows:-
This invention relates to novel and useful improvements in the means or method of
connecting the pickers with the picking sticks in looms for weaving and in
communicating motion therefrom to such pickers, and its object is to obviate the use
of picking straps and to provide a more durable connection capable of imparting a
sinooth and accelerating motion to the picker.
For this purpose we hinge or. pivot an arm to the outer end of the shuttle box, the
upper end of which extends approximately to the level of the picking stick, and is
attached thereto by means of a suitably constructed chain, or by coupling rods hinged
together in such a manner that they always bend in one direction. The said coupling
rods are connected to the picking stick by means of a swivel and universal joint, and
are hinged to the arm mounted on the end of the shuttle box or vice versa.
connecting rod is hinged at the top to the said arm and inclining down towards the
shuttle box is attached by a hinge joint to a suitable metallic or other picker.
A
The various parts are so relatively arranged that before the picking stick is operated
the said arm hinged to the end of the shuttle box and the said rod connecting such
arm to the picker lie at an acute angle to each other. But when the picking stick is
actuated the said arm is inclined as the top is drawn inwards and as the said connecting
rod attached thereto is pushed or driven along the shuttle box the angle it formed

page_text: with the said arm is extended to a more obtuse one, thus the motion imparted to the
picker becomes faster and stronger as it traverses the box, thereby conveying a smooth
and accelerating impulse to the shuttle. A spring or springs is, or are arranged to
return the parts to their original position after a pick has been made. And a
similar arrangement is employed at the other side of the loom to connect the picker
with the picking stick.

When ordinary pickers are employed we use a shell or connection, which may be
mounted in the manner above described, adapted to be hinged to the end of the said
connecting rod and enclose or be attached to the picker.

page_text: Improvements in the Means or Method of Connecting the Pickers
with the Picking Sticks of Looms for Weaving and in
Communicating Motion therefrom to such Pickers.
We, HEZEKIAH LISTER, and LOTON LISTER, of High Street, Great Horton, in the
County of York, Boot Manufacturers, and FRANK CROSSLEY LISTER, of Halstead
Place, Great Horton aforesaid, Mechanic, and GEORGE THEWLIS, of Prospect Place,
Farsley in the said County, Weaving Overlooker, 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 :-
This invention relates to novel and useful improvements in the means or method of
connecting the pickers with the picker sticks in looms for weaving and in
communicating motion therefrom to such pickers, and its object is to dispense with
the leather picking straps commonly used and to provide more durable connections
capable of imparting a smooth and accelerating motion to the pickers.
The said improvements consist of the arrangements hereinafter described in which
arms or levers connect the picker with the outer end of the shuttle box and are
connected to the picking stick by a chain or its equivalent in a suitable manner to
impart a smooth and accelerating motion to the picker from the picking stick.
Reference is to be had to the accompanying drawing forming a part of this
specification, in which similar letters of reference indicate corresponding parts in all
the figures.
Figure 1, represents a front elevation of such parts of a loom as are necessary to
illustrate our invention, the mechanism on the left hand side being shown in the
position it occupies before a pick is made and the other side represents the position of
the parts after a pick is made. Figure 2, is a plan and figure 3, is an end view of
the same.
Figure 4, is a back view and figure 5, is an end view on a larger scale of the end
of the shuttle box and attachments thereto.
Figure 6, is a plan and figure 7, an end view of the picker.
The arm or lever A is hinged by the pivot B between knuckles C formed at the top
of the plate D secured to the outer end of the shuttle box E. A connecting rod .F
pivoted at its lower end by the pin G between lugs I on the picker His hinged above
to the top end of the lever A. And the rod F is connected by a chain J to the end
of the picking stick K, which is operated in the usual manner.
The various parts are so relatively arranged that before a pick is made the lever A
and the connecting rod F lie at an acute angle to each other, but when the picking
stick K is operated the lever A is inclined as the rod F is drawn inwards by the
chain J, thus increasing the angle between A and F to an obtuse one and imparting a
smooth and accelerating motion to the picker pivoted to the rod F and sliding on the
picker spindle O.

page_text: The lever A is rigidly secured to the pivot B by the set screw P and an arm M
fixed to the back end of such pivot is connected to a spring L attached below to the
stud or screw R, thus after a pick has been made the said spring restores the parts to
their original position.
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:
1. The general construction and arrangements of parts constituting the connection
between the picker and the picking stick, substantially as herein shown and
described.
2. The combination with a shuttle box, of the lever A and connecting rod F,
substantially as herein shown and described and for the purpose specified.
3. The combination with said lever A and rod F, of the chain J or its equivalent,
substantially as herein shown and described.
4. The combination with said lever A and rod F, of a spring adapted to restore the
parts to their original position after a pick has been made, substantially as herein
shown and described.
