Improvements in Means for Checking Pickers in Looms for Weaving.
We, JOHN WILSON of Barnett Square, Armley, Loom Turner; CLARENCE GLOVER,
of Laburnum House, Wortley, Gentleman; HERBERT GLOVER; of Laburnum
House Wortley, aforesaid, Gentleman; and GEORGE HENSON, of Low Mill Yard,
Wortley, aforesaid, Mechanic; all in the City of Leeds, do hereby declare the
nature of this invention to be as follows:-
The object of our invention is to provide a new or improved picking stop
arrangement so as to lessen the impact between the picker and stop when deliver-
ing the shuttle; so effecting a great saving in wear and tear.
According to our invention we employ a boss or stop which is bolted or otherwise
secured to the "going part" of the loom similar to the old stops. The said boss
or stop has a cavity or hole in which fits, preferably, a spiral spring so as to form
an elastic cushion. One end of the picker spindle passes through the spring or
elastic cushion, and is secured in a suitable hole adjoining the other one by means.
of a setscrew arranged in the said boss or stop, so that the said spindle can be fixed,
Icosened, or adjusted, as required; the opposite end of the said spindle is fixed
in a cup or plate on the shuttle box end.
Working in conjunction with the said spring, or elastic cushion, is a buftr
slidable, or movable on the said spindle having a front plate or surface for the
picker to strike against when or after. propelling the shuttle.
At the back of the front plate or surface is a shank or tube like termination,
which is adapted to work in the hole or cavity in the said boss or stop and normally
abuts against the said spring or elastic cushion. The movement of the said buffer
is regulated by a slotted plate, or link, which is secured at one end by a rivet, stud,
setscrew, or other suitable means, and the slotted part works with a pin or stud.
The action is as follows:-
As
On the picker propelling the shuttle, at the delivery of the same, the motion
of the picker is arrested by coming in contact with the buffer which compresses
the spring or elastic cushion, sa reducing the impact or force of the blow.
soon as the motion of the picker is arrested the spring or elastic cushion normally
resumes its position, so forcing out the buffer ready for the next blow, the buffer
being controlled and kept in position by the slotted plate or link.
By the use of our invention a great saving in the wear and tear of pickers,
picking bands picking sticks, and other parts is effected.

House, Wortley, Gentleman, and GEORGE HENSON, of Low Mill Yard, Wortley,
Mechanic, all in the City of Leeds, 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 our invention is to provide a new or improved picking stop

DESCRIPTION OF DRAWINGS.
Fig. 1 is a plan of our improved means.
Fig. 2, is an end view, and Fig. 3.a front view of Fig. 1.
Fig. 4, is a plan partially in section of the underside of a modification of our
invention.
Fig. 5, is a plan showing our invention adapted for two spindles.
Fig. 6, is a view showing our invention applied to a loom.
According to our invention we employ a boss or stop A which is bolted, or
otherwise secured to the "going part" of the loom similar to the old stops. The
said boss or stop A has a cavity or hole B in which fits preferably a spiral spring C,.
so as to form an elastic cushion.
One end of the picker spindle D passes through the spring or clastic cushion C,
and is secured in a suitable hole E adjoining the other one B by means of a set
screw F arranged in the said boss or stop A, so that the said spindle D can be
fixed, loosened, or adjusted as required, the opposite end of the said spindle D is
fixed in a cup or plate E on the shuttle box end.
Working in conjunction with the said spring or elastic cushion C, is a buffer H
slidable or movable on the said spindle D'having a front plate or surface J for
the picker K to strike against when or after propelling the shuttle.
At the back of the front plate, or surface J is à shank or tube like termination L
which is adapted to work in the hole or cavity B in the said boss or stop A, and
normally abuts against the said spring or clastic cushion C. The movement of
the said buffer H is regulated by a slotted plate or link M, which is secured at
one end by a rivet stud, setscrew F, or. other suitable means, and the slotted part
works with a pin or stud N.
The action is as follows:-
On the picker K propelling the shuttle, at the delivery of the same, the motion
of the picker is arrested by coming in contact with the buffer H which compresses
the spring or elastic cushion so reducing the impact or force of the blow. As
soon as the motion of the picker K is arrested the spring or elastic cushion, C
normally resumes its position so forcing out the butter H ready for the next blow,
the buffer H being controlled and kept in position by the slotted plate or link M.
In the modification shown in Fig. 4, the end of the buffer H is made with one or
more taper sides H, or projections, and the hole B in the boss or stop A has a
corresponding taper side or sides, by this means the movement of the buffer H is
controlled or regulated, and the slotted plate or link M with its connections is
dispensed with..
We may use either a spiral spring as shown in Fig. 1, or a conical or coiled
spring as shown in Fig. 4, or indiarubber, in lieu of either.
Our said invention can be made for one, two, or more picker spindles, as
required and is adaptable to any class of looms.

page_text: By the use of our invention a great saving in the wear and tear of pickers,
picking bands, picking sticks, and other parts is obtained.
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 looms for weaving, the combination with the "going part" of a boss or
stop, having a spring or elastic cushion and buffer for the picker to strike against
substantially as and for the purposes set forth.
2. The improved means for checking pickers in looms for weaving, substantially
as shown and described.
