page_text: I JOHN KNOWLES of 8 Minnie Terrace, Alexandra Road Duke's Brow Blackburn
in the County of Lancaster, Machinist, 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 :-
My Invention relates to that part of the power loom, known as the picking motion,
or the propelling of the shuttle across the loom ; and have for their object the simpli-
cation of the power loom for weaving.
And for this purpose I place a toothed pinion wheel on, and revolves with the crank
shaft. Over or under this pinion I mount on a suitable fixing a toothed disc wheel,
either parallel or at right angles with the loom framing-This disc wheel receives its
motion from the aforesaid pinion on the crank shaft.
On the above disc wheel I fix a picking tappet or a picking bowl.
The picking rod being placed nearly in a horizontal position over the before named
disc wheel, one end of which is mounted on a stud, or suitable fixing, near the back
part of the loom. The front end of this picking rod is provided with a slot in it-
through which passes a pin on the picker provided for that purpose; or the picking
rod can pass between two spindles one above the other, which will keep the picker
more steady.
From the fulcrum or central shaft of the above picking rod, a short arm projects,
on which arm I fix a friction bowl, so that when the picking tappet, on the disc wheel,
comes into contact with the said bowl, the shuttle in the shuttle box is propelled across
the loom, And when a friction bowl is fixed on the disc wheel, I fix a picking nib on
the projecting arm on the fulcrum of the picking rod.
These picking bowls or nibs comes into contact alternately, at each end of the
loom, and so propels the shuttle suddenly from one side of the loom to the other.

page_text: When what is known as the underpick motion is required, I place the tappet on the
disc wheel in a vertical position, and the picking rod is connected to the heel of the
ordinary underpicking rod.
When two or more picks are required from one side of the loom or what is known
as pick and pick.
The picking tappet or bowl on the disc wheel is provided with a clutch box and is
actuated by a fork lever and chain mounted on crank shaft.
By this novel means a great saving is effected in the construction of the loom,
and much greater economy is attained in the working of the power loom than is the
case in the ordinary loom.
My Invention will be better understood by reference to the accompanying sheet of
drawings.
Fig. 1-is a plan view of one end of a loom with those improvements attached.
Fig. 2 is an end view of same.
Fig. 3 is a plan view of these improvements, when underpick looms are used.
Fig. 4 is an end view of Fig. 3.
Fig. 5 is an end view of my improvements when applied to pick and pick
looms.
Fig. 6-shows the driving wheel and star wheel used in Fig. 5.
Fig. 7-is a plan view of disc wheel and tappet, showing tappet on the side of the
ring.
Fig. 8-is end view of disc wheel showing tappet on ring in a vertical position.
Fig. 9 is a plan view showing disc wheel in a parallel position to the crank
shaft.
It will be observed that the same letters and figures represent the same parts in
each figure.
A is the loom frame-B is the slay-C-is the crank shaft-D is the pinion
E is the disc wheel-F is the picking tappet.
1 is the picking lever used in underpick looms-2 is underpicking stick-3 is
picking rod showing slot over picker 5-4 is the central shaft showing projecting
arın 5-6 and 6¹ are brackets in which central shaft 4 rocks in points 9 and 91.
It will thus be seen that when the crank shaft C Figs. 1 and 2 revolves the pinion D
will cause the disc wheel E to revolve once every two revolutions of the crank shaft
which will cause the picking tappet F to come into contact with bowl 8 on short
arm 5. This will cause the picking rod 3 to make a sudden movement inwards and
by means of picker 5¹ will propel the shuttle from one side of the loom; a similar
arrangement on the other side will have a like effect.
The brackets 6 and 6¹ are provided with conical recesses 9 and 9¹ into which
central shaft 4 is kept in position, thereby reducing the friction to a minimum.
7 Figs. 1-2 and 9 is a toothed bracket for the purpose of keeping the picking rod
in its position, when once arranged for weaving.
Figs. 3 and 4 is a modification of the above arrangement to be applied in underpick
looms; the disc wheel E is placed under the pinion D; and lever 1 is connected to
the heel of picking rod 2-at 21 by link 3¹. The tappet F coming into contact with
bowl 8 on lever 1, causes the picking rod 2 to have a forward motion which propels
through the medium of the picker 5' the shuttle across the loom.
Fig. 5 is a plan view of my improvements when two or more picks are required
from one side of the loom to the other or pick & pick.
On the crank shaft C-Figs. 5 and 6, I place a driving wheel 4, and beside it the
star wheel 51-To this star wheel 5 is attached a boss 81 in which is made a zigzag
groove 71 in which groove one end of lever 6' rests; the other end of this lever, 6' rests in
groove formed in the boss of tappet plate 91; and at each revolution of driving
wheel 4 a section of the star wheel 5" is moved which causes the tappet plate 9¹ to
have a reciprocating motion imparted to it by means of the lever 6¹, so that at every
alternate movement of the star wheel 5" the picking tappet plate 9¹ is caused to fall
in and out of gear, with picking bowl 8.

page_text: Fig. 9 is a modification of these improvements-C is the crank shaft-D is a bevel
pinion E is a disc which placed parallel with the crank shaft C, on which is fixed
tappet F which actuates bowl 8.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed I declare what I
claim is
1st. Mounting the picking rods on central points and actuating them in the manner
substantially as set forth and described.
2nd. The dispensing with picking bands substantially as set forth and described.
3rd. The manner of actuating the picking rods of pick and pick looms substantially
as set forth and described.
4th. The manner of actuating the picking rods of underpick looms substantially as
set forth and described.
5th. The placing of the disc wheel parallel with the crank shaft substantially as set
forth and described and represented in the several figures of the accompanying sheet
of drawings.
