I, ARTHUR SOWDEN, of Glen-aire, Baildon, in the County of York, Machine
Maker, do hereby declare the nature of this invention to be as follows:-
This invention relates-Firstly, to improved apparatus for preventing upward
or lifting motion of the picking cone. Secondly for putting the picking cone
in and out of working. Thirdly, apparatus for easing the movement of the
pattern barrel operating lever. Fourthly, for steadying the shuttle box rod in
its ascent and descent. Fifthly, for steadying and holding the nogging wheels
for operating the boxes (of drop or revolving shuttle boxes). Sixthly, for locking
the picking shaft after it has made its required movement.
For preventing the upward movement of the picking cone, the latter is mounted
on a carrying stud in which is formed a square or other recess within which
is a corresponding piece carried by a metal strap or bracket over the carrying
stud referred to, admitting of the required sideway movement of the cone, but
preventing its rising or lifting.
For throwing the picking clutch in and out of gear, a connecting rod is
employed and the said rod is jointed at a convenient point of its length by links
so that the rod is in effect similar to a broken backed lever or escapement, said
rod is connected with the movable part of the clutch, a cranked lever acts on the
linked part of the rod and is operated by hand lever and connecting rods
from the front of the loom as ordinary.
For easing the movement of the spur or fork lever which turns the peg or
pattern barrel there is provided a crank or arm on the handle for controlling the
picking tappets and through the crank or arm is a slot and pin. Within the
slot is received the flat end of the rod connected with the peg or pattern barrel,
a recess or notch in the end of the said rod holds the rod on the pin unless
released for reversal of the said barrel. The connection between the rod and
barrel comprise a crank arm or finger and connecting spring which admits of
a slight elastic movement of the lower arm of the fork lever whereby a smoother
movement is attained and risk of breakage is decreased.
For steadying the shuttle box rod, a friction disc device is applied and con-
nected with the box rod, there being a stop piece (carried on a support at the
end of the loom) which brings the friction device into operation or is employed
in connection with an arc or curved surface and shoe which act as frictional
or brake surfaces and steady the movement of the box rod.
The nogging wheels which operate the shuttle boxes (drop or rotary boxes) are
provided with a friction device so as to prevent the said wheels moving when not
in actual work, there being in connection with the friction device or disc having
a recess in its periphery or a flat place, in or on which is received a holding
bowl or flat part of a lever arm carried at one end on a stud and bearing on
the disc, and having a spring or weight at its other end.
For locking the picking shaft so as to prevent the vibration of the picking

page_text: arm, the cone and picker, whereby the latter is liable through the vibration to
be shaken and moved into end of the boxes when not required to pick there
is applied to the picking shaft a finger and bowl which is engaged by a recess
or clip in an arm mounted and free to move on its carrier, the clip and recess
engage the finger or bowl when the pick is made and they are held together,
a spring admits of their release for return pick, a slight incline on the upper
surface of the lever forms an easing movement, or an eccentric and strap may
be employed in connection with the picking shaft, for holding and steadying
the parts.
Dated this 27th day of August 1807
I, ARTHUR SOWDEN, of Glen-aire, Baildon, in the County of York, Machine
Maker, 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 improvements in looms for weaving and consists:-
Firstly of improved picking clutches or apparatus for preventing upward or
lifting motion of the picking cone. Secondly, of improvements in the method
of and means employed for putting the picking cone in and out of operation.
Thirdly, of apparatus for easing the movement of the pattern barrel operating
lever. Fourthly, of appliances for steadying the shuttle box rod in its ascent
and descent. Fifthly, of appliances for steadying and holding the nogging
wheels for operating the shuttle boxes (of drop or revolving shuttle boxes).
Sixthly of appliances for locking the picking shaft after it has made its required
movement.
Such being the nature and object of my said invention, the following is a
complete description of same reference being had to the accompanying drawings,
in which:-
Fig. 1 is a back elevation of part of a loom having my improvements applied
thereto.
Fig. 2 is an end elevation of part of a loom showing the box rod and levers
with the improved frictional device applied thereto.
Fig. 3 is a plan view of part of Fig. 2.
Fig. 4 is a front elevation of the frictional or checking device applied to the
nogging wheels for operating the shuttle boxes and picking motion.
Fig. 5 is a plan view of the device for locking the picking shaft.
According to this invention for preventing the upward movement of the pick-
ing cones 1 (see Fig. 1) the latter are mounted on carrying studs 2 each fixed
to a bracket 3 in which is formed a square or other recess 4 within which is
received a corresponding piece or projection 5 carried by a metal strap or bracket 6
above the carrying stud 2 referred to. The above described arrangement admits
of the required sideway or lateral movement of the cone 1 but prevents its rising
or lifting.
For throwing the picking clutch 6-6, in and out of gear a connecting rod 7
supported in brackets 7" 7" is employed and the said rod 7 is jointed at a con-
venient point of its length by links 8-8 and pin 9 so that the rod 7 is in effect

page_text: similar to a broken backed lever or escapement, and said rod 7 is connected
at each end with the movable fork 10 of the clutches 6-6. A cranked lever 11
acts on the linked or jointed part of the rod 7 and is operated by hand lever 12
and connecting rods 13 from the front of the loom as ordinary.
The springs 14, 14 tend to shorten the rod 7 by folding the links 8, 8 and
as the rod 7 is shortened the forks 10, 10 turning on their fulcrum 15, 15 depress
the upper parts or halves of the clutches 6, 6, and the picking cones 1 are in
gear. When the hand lever 12 is depressed the connecting rod 13 depresses the
cranked lever 11 and the latter pressing on the links or joint 8, the latter is
straightened and the rod 7 lengthened (the springs 14, 14 being expanded) and
the clutches 6, 6 disengaged and the picking cones 1, 1 are out of gear or loose
on their shafts.
For easing the movement of the spur or fork lever 16 which turns the peg
or pattern barrel 17 there is provided a crank or arm 18 on the handle 12 for
controlling the picking cones 1, 1, and through the crank or arm is a slot and
pin 19. Within the slot is received the flat end 20 of the rod 21 connected with tho
ordinary peg or pattern indicating barrel for controlling the shedding mechanism,
a recess or notch 22 in the end of the said rod 21 holds the rod 21 on the pin 19
unless released for reversal of the said barrel. The connection between the rod 21
and barrel comprises a crank arm or finger 23 and connecting spring 24 which
admits of a slight elastic movement of the lower arm 25 of the fork lever 16
whereby a smoother movement is attained and risk of breakage is decreased.
For steadying the shuttle box rod 26 (see Figs. 2 and 3) a friction dise device 27
is applied, such frictional device comprising two plates or discs 28, 28 (see Fig. 3)
mounted on a stud 29 and nipped together with an intervening washer or ring
of leather or other soft substance 30 by means of the nut 31. The cranked disc 28
when the frictional resistance is overcome has a certain amount of motion
allowed it, but governed by the stop piece 32 projecting into the recess 33 in
the disc 28, said stop piece being carried on a support 34 in the end of the frame
of the loom. The end of the cranked disc 28 is connected with the box rod
lever 34 by rod 35' which brings the friction device into operation, and this
frictional device may be employed in connection with an arc or curved surface 36
on the lever 34 and brake shoe 37 fixed to the loom frame, which act as further
frictional or brake surfaces and steady the movement of the box rod lever 34
and box rod 26. The amount of friction or bite of the shoe 37 can be regulated
by the nuts and screws 39, 39.
The ordinary and well-known nogging wheels (see Fig. 4) which operate the
shuttle boxes (drop or rotary boxes) are provided with a frictional device such
as illustrated, so as to prevent the said wheels moving when not in actual work,
their being in connection with the friction device a disc 41 having a recess or
recesses 42 in the periphery or a flat place in or on which is received a holding
bowl or a lever arm 43 carried at one end on a stud 44 and bearing on the disc 41
and having a spring 45 or weight at its other end.
For locking the picking shaft 42" (see Fig. 5) so as to prevent the vibration
of the picking arm, the cone and picker, whereby the latter is liable through
the vibration to be shaken and moved into end of the boxes when not required
to pick there is applied to the picking shaft 42" a finger 43" and bowl 44"
which is engaged by a recess or clip 45 in an arm 46 mounted and free to move
on its carrier 47, the clip and recess 45ª engage the finger or bowl 44 when
the pick is made, and they are held together by a spring 48 which admits of
their release for return pick, a slight incline 49 on the edge of the arm 46 forms
an easing movement.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
