IMPROVEMENTS IN APPARATUS FOR EFFECTING THE "PICKING-MOTION" IN LOOMS FOR WEAVING
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We, WILLIAM LAWTON HINDLEY, Manufacturer, and JOSEPH CALDWELL, Over-
looker, both of Farnworth near Bolton in the County of Lancaster, do hereby
declare the nature of our Invention for "IMPROVEMENTS IN APPARATUS FOR
EFFECTING THE "PICKING-MOTION" IN LOOMS FOR WEAVING," to be as
follows:-
$8
This Invention relates to an improved method of operating or effecting the
picking-motion" in looms for weaving, and consists in fixing to the framing of
the loom a suitable fixing or bracket in which slides a bar or slide provided with a
hole or boss in which is placed or held the top end of the picking shaft, the bottom
end being held and supported by a bevelled or taper footstep to allow of the
oscillation required by the action of the said picking shaft.
On the side of the spur wheel for operating the weft motion, is placed a cam
which effects or causes the sliding action of the slide when required, which is, when
the shuttle is to be thrown through the shed on the slay. This cam pushes or
presses the slide and the top end of the picking shaft laterally, thus placing the
swivelling tongue or lever on the picking shaft in position to be operated or
swivelled radially by a cam fixed on the fly or hand wheel on the crank shaft of
the loom, which operation throws or jerks the picking spindle or rod by means of
the usual strap connections, and thus effects the requisite action required' to propel
the shuttle in and through the shed to the opposite end, from whence it is returned
by similar means fixed on that end, and so on continuously.
After the propelling and oscillating cams have released the slide and tongue,
they are with the picking shaft forced again in position for the next throw by a
suitable spring fixed to the frame work of the loom.
This apparatus is placed at each end of the loom, each side effecting or performing
its own operation, thus causing each end to operate only once in two picks or
throws of the shuttle.

looker, both of Farnworth near Bolton in the County of Lancaster, do hereby
declare the nature of our Invention for "IMPROVEMENTS IN APPARATUS FOR

manner the same is to be performed; to be particularly described and ascertained
in and by the following statement:-
"
This Invention relates to an improved method of operating or effecting the
'picking-motion" in looms for weaving, and consists in fixing to the framing of
the loom a suitable fixing or bracket, in which slides a bar or slide provided with
a hole or boss in which is placed or held the top end of the picking shaft, the
bottom end being held and supported by a bevelled or taper footstep to allow of
the oscillation required by the action of the said picking shaft.

On the side of the spur wheel for operating the weft motion is placed a cam
which effects or causes the sliding action of the slide when required, which is,
when the shuttle is to be thrown through the shed on the slay. This cam pushes
or presses the slide and the top end of the picking shaft laterally, thus placing the
swivelling tongue or lever on, the picking shaft in position to be operated or
świvelled radially by a cam fixed on the fly or hand wheel on the crank shaft of
the loom, which operation throws or jerks the picking spindle or rod by means of
the usual strap connections, and thus effects the requisite action required to propel
the shuttle in and through the "shed" to the opposite end, from whence it is
returned by similar means fixed on that end of the loom, and so on continuously.
"
After the propelling and swivelling cams have released the slide and tongue,
they are with the picking shaft forced again in position for the next throw by a
suitable spring fixed to the frame work of the loom.
This apparatus is placed at each end of the loom, each end effecting or performing
its own operation, thus causing each end to operate only once in two picks or
throws of the shuttle.
In order that our Invention may be fully understood and readily carried into
operation, we will now proceed to describe the accompanying Sheet of Drawings,
which represents part of a loom to which our improvements are applied; similar
letters of reference indicate like parts throughout the Drawings.
Fig. 1 represents a part side elevation of a loom with our improved "picking
motion" applied. Fig. 2 is a front view of the same fixed to one end of a loom,
being the same at the opposite end. Fig. 3 is a plan of the same when liberated
from: the action of the operating cams, and Fig. 4 is a plan shewing the position of
the picking shaft and connections when operated by the cams.
A is a fixing or bracket secured to the framing C of the loom; in this fixing or
bracket the bar B slides, in which is placed the top end of the picking shaft D,
the bottom end of the latter being held and supported in the bevelled or taper
footstep E.
On each end of the loom is mounted on the weft motion wheel or shaft M the
cam F, which slides or pushes the bar B with the picking shaft D laterally, thus
placing the tongue G in position to be swivelled radially by the cam H fixed on
the fly wheel I as in Fig. 4, which gives the motion to the picking stick J by means
of the usual strap connections K.
After the oscillating and swivelling cams F and H have released the slide B and
tongue G, the latter are with the picking shaft D placed in position for the next
throw by the spring L fixed to the frame C of the loom. This apparatus is set

page_text: or timed so that each end only operates once in two picks or throws of the
shuttle.
In some cases the position of the weft motion shaft M varies, in which the
angular projection on the slide bar B is placed to suit, as in Fig. 5..
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:—
The picking shaft D provided with the swivelling tongue G and the slide B
actuated by the cams F and H, and the spring L, applied and operating
substantially as described and as shewn on the Drawings.
