I JOHN MONк of the Peel Hall Foundry Preston in the County of Lancaster
Machinist and Ironfounder do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the simplifying of the picking motion of looms
for weaving so that it may consist of fewer parts, occupy less space, be more easy of
access, and be more durable than other arrangements of such apparatus heretofore
known to me.

"2
Instead of employing the tappet shaft for actuating the picking motion I employ the
crank shaft and thereby am enabled to dispense with the ordinary picking shafts." At
each end of the loom I mount a toothed wheel (which also constitutes the picking
block) upon a stud fastened to the framing of the loom and into this wheel (hereinafter
called the "picking block wheel ") is geared a second toothed wheel fastened upon and
rotating with the crank shaft. The second wheel has only half the number of teeth
of the picking block wheel in order that the latter may perform only one revolution
for the crank shaft two, the required motion for each alternate pick being thereby
obtained. I employ an ordinary picking plate or "picking tappet" fastened to the
outer face of the picking block wheel by any of the usual methods the picking plate
which at each
being provided with the usual sloping projecting part or
revolution strikes against a picking bowl arranged (according to this invention) upon
a horizontal stud fastened to the lower extremity of a vertical swivelling stud or axis
mounted in a suitable bearing and which rotates at each pick to the extent of about
one quarter of a turn in the same manner as obtains with the ordinary picking shaft.
The picking stick is secured to the lower part of the vertical swivelling stud or axis
and its outer end may be so arranged as to work directly on to the picker in which
case the ordinary picking strap or band may be dispensed with. The wheel gearing
and attendant mechanism as above described is so arranged at each end of the loom as
to perform the pick first at one end and then at the other as will be well understood.
The ordinary or any convenient arrangement of spring or equivalent device may
be employed for bringing each picking stick and its bowl back to its former position
after each pick.

page_text: I JOHN MONK, of Peel Hall Foundry, Preston, in the county of Lancaster,
Machinist and Ironfounder, 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 has for its object the simplifying of the picking motion of looms for
weaving, so that it may consist of fewer parts, occupy less space, be more casy of
access, and be more durable than any other arrangements of such apparatus heretofore
known to me.
Instead of employing the ordinary tappet shaft driven by a wheel below the crank
shaft, as in ordinary overpick looms, for actuating the picking motion I employ
wheel fixed above the crank shaft at each end of the loom, and called the picking
block wheel, this wheel is upon a stud or bush fastened to the loom frame.
The wheel upon the crank shaft at each end has only half the number of teeth to the
picking block wheel into which it gears, so that the latter may perform only one
revolution for the crank shaft two, the required motion for each alternate pick being
thereby obtained.
I employ an ordinary picking plate or picking tappet, fastened to the outer face of
the picking block wheel by any of the usual methods, and rotating with the wheel,
the picking plate or tappet being provided with the usual sloping projecting part or
nose, which at each revolution strikes. upon a picking bowl arranged (according to
this invention) upon a horizontal stud fastened to the lower extremity of a vertical
stud or axis, or cast with the vertical stud mounted in a suitable bearing and which
rotates and acts in the same manner as the ordinary picking shaft.
In addition to the strength of the pick being regulated by the length of the nose of
the picking tappet, or by the catch or clutch box, it can also be regulated by adjusting
the bracket or bearing which carries the vertical stud.
The picking stick is attached to the upper or lower part of the vertical swivelling
stud or axis, and its outer end may be so arranged as to work directly on to or through
the picker in which case the ordinary picking strap or band may be dispensed
with.
.1
The picking stick for this improved picking motion may be made of steel, iron, or
other metal, with the ends of wood, or any other light material, to carry the picking
band, or they may be made of wood as ordinary.
The wheel gearing and attendant mechanism as above described is so arranged at
each end of the loom, so as to perform the pick first at one end, and then at the other,
as will be well understood.
The ordinary or any convenient arrangement of spring or equivalent device may be
employed for bringing each picking stick and its bowl back to its former position after

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1. is a side elevation of loom frame with my picking motion applied.
Fig. 2. is an end view of Fig. 1.
Figs. 3 and 4. are enlarged back and front views of picking tappet.
Fig. 5. is an enlarged view of picking bowl, stud, and bracket.
A is the loom frame, B is the crank shaft upon which is the small pinion wheel C,
gearing into the picking block wheel D (which has double the number of teeth) upon
the stud E, attached to this wheel and upon the stud E, or upon the boss of the wheel
is the picking tappet F which may either be constructed in two pieces secured together
by the bolt G, and fixed to the picking block wheel by the bolts G' and G³, or by other
suitable means, or it may be made in one piece.
This picking block which is at right angles to the crank shaft, operates upon and
strikes the picking bowl H, which is in a horizontal position upon the stud or axis J
at the lower extremity of the vertical swivelling stud or bush K, (instead of the bush K
a wrought shaft or stud might be used) carried in the bracket L which is secured to a
bracket M from the loom frame A, this bracket may be cast upon the loom frame, or
loose, and attached thereto with bolts or other means.
At the upper part of the vertical swivelling stud K is attached the picking stick or
arm N which is preferably of steel, or other metal, having a wood end P, for holding
the picking strap, or the picking straps may be dispensed with by its outer end
being arranged so as to work directly on to the picker, as shown by dotted lines N' on
Fig. 1.
The bolt R passes through the bush K, and picking arm N, and secures the whole
together, the springs S return the picking arms after each stroke, T is the brake wheel,
and U the driving pulleys.
V is the catch or clutch box as employed in ordinary looms to regulate the
pick.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I would have it understood
that I place the large wheel above the small wheel, and the picking bowl is held
in a horizontal position, with this and the peculiar position of the vertical
swivelling stud a very easy motion is obtained, and I declare that what I
claim is
1. The arrangement and position of the picking tappet F operating upon the
horizontal bowl H, as and for the purposes shown and described.
2. The combination of the picking tappet F, bowl H, stud J, bush K, in the
bracket L, and the picking arm or stick N, operated as shown and described.
Dated this Nineteenth day of April 1888.
