Specification Accepted, 6th Apr., 1889
Fig. 2. is a front elevation.
Fig. 3 is a plan of Fig. 2.
Figs. 4. and 5 are detail views.
According to our invention we employ a picking wheel A carried on a stud B and
bracket B¹ affixed or bolted preferably to the loom frame C. Attached to the said
picking wheel A is a chain or strap Ď to which is fixed a spring E, the lower end of
which is fastened to a lever F pivotted on a stud F¹ upon the loom frame C. Operating
as hereinafter setforth upon the said lever F is a runner G carried on a stud on the
crank, tappet, or arm H which is carried on the tappet shaft J.
At the end of the shuttle box K₁ we employ a pulley L (preferably in section),
which is carried on a stud M on the bracket N, the said bracket being affixed to the
end of the shuttle box K¹. The said pulley L is also provided with a boss or bush O
to which is fastened a chain or strap P and to which is fixed a spring R fastened at its
other extremity to the back of the shuttle box K¹ by means of the book S.
Affixed to the picking wheel A is a stud A' terminating in a disc A2 which may be
either fixed or movable and which works in the slide A³ upon the slay K.
From the said picking wheel A to the picker T we provide a strap or chain T¹ and
from the said picker to the pulley L we provide a strap or chain T.

page_text: The action is as follows:
The crank shaft revolves twice to the tappet shaft once, at every second or every
other revolution of the crank shaft the tappet shaft J revolves, whereby the runner G
upon the crank or arm H is brought to bear upon and depress the lever F according
to the extent of the revolution of the said tappet shaft J, by the said runner G
depressing the lever F the spring E is expanded or opened and the picking_wheel A
is held in or under the slide A3 (by means of the disc A²) until the slay K moves
forwards with the slide A³ when the said slide clears the disc A² thus releasing the
picking wheel A and allowing or causing the same to suddenly revolve, (owing to the
pressure or pulling strain imparted to it by the runner G depressing the lever F)
thus pulling or drawing forwards the picker T so as to pick, by means of the strap or
chain T after which (when the runner G has ceased to depress the lever F) the
picker T is returned to the end of its traverse in the shuttle box K' and the
disc A2 is again brought into position for the slide A³ to act upon it by incans of
the pulley L, spring R at the side of the shuttle box K', and strap or chain T
connecting the picker T to the pulley L.
When used for "box" looms or looms having jacquards, a rod from the jacquard
or dobby is connected to the lever F, and a double movable crank or arm is
employed to depress and raise the said lever and so operate the picker as required.
We may also provide a second runner upon the said lever F, and upon which
the runner G may operate, and thus depress the lever F more quickly, thereby
increasing the rapidity of the motion.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we would have it understood
that we do not confine or limit ourselves to the exact positions shown and described
for applying our improvements as it may be necessary in order to suit the different
makes of looms to modify the same, but we declare that what we do claim is :-
1. The employment of the spring or springs E, chain D and lever F for
operating the picking wheel A substantially as shown and described.
2. Releasing the picking motion at the proper time substantially as shown and
described.
3. The combination of the picking wheel A. springs E, lever F, runner G upon
crank H, straps or chains D. T1 and T2, spring R, and pulley L as and for the
purposes shown and described.
4. The general arrangement of picking motion substantially as shown and
described.
