PROVISIONAL SPECIFICATION.
Improvements in or relating to the Picking Motion of Looms
for Weaving.
I, ABRAHAM WOOD of 55 Bridge Street, Rambsbottom near Bury in the
County of Lancaster, Jeweller, do hereby declare the nature of my said invention
to be as follows:-
This invention refers to improvements in or relating to the picking motion of
looms for weaving and consists in constructing the picker of metal, buffalo hide,
leather, or other suitable material. The end of the picker that operates on the
shuttle may be lined with leather, compressed paper, buffalo hide, or other material
or substance. The picker is constructed to slide in a metallic frame, and is
operated to throw the shuttle by a band or belt passing over a pulley. The
band or belt is attached to a rod or arm mounted on a shaft; the latter being
provided with a lever carrying a bowl, which are operated by a cam on the cam
shaft. The metallic or other picker after operating the shuttle is returned to
its original position by a spring. Sliding stops are provided at each end of the
metallic frame and are fitted with springs to break the force of the blow of the
picker and shuttle. The ends of the stops are fitted with linings of leather or other
material to form a cushion. The metal frame is attached in any convenient
manner to the lathe of the loom, and is designed to dispense with the ordinary
shuttle-box. This invention is intended to also dispense with the usual picking
stick and band. The metallic frame is fitted with a swivelling lever or other
equivalents to allow of the picker being inserted or removed at will.

Improvements in or relating to the Picking Motion of Looms
for Weaving.
I, ABRAHAM WOOD of 55 Bridge Street, Ramsbottom near Bury in the
County of Lancaster, Jeweller, do hereby declare the nature of my said 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 refers to improvements in or relating to the picking motion of
looms for weaving and consists in constructing the picker of metal, buffalo hide,
leather, or other suitable material. The end of the picker that operates on the
shuttle may be lined with leather, compressed paper, buffalo hide, or other material
or substance. The picker is constructed to slide in a metallic frame, and is
operated to throw the shuttle by a band or belt passing over a pulley. The band
or belt is attached to a rod or arm mounted on a shaft; the latter being provided
with a lever carrying a bowl, which are operated by a cam on the cam shaft. The
metallic or other picker after operating the shuttle is returned to its original
position by a spring. Sliding stops are provided at each end of the metallic frame
and are fitted with springs to break the force of the blow of the picker and shuttle.
The ends of the stops are fitted with linings of leather or other material to form a
cushion. The metal frame is attached in any convenient manner to the lathe of
the loom. This invention is intended to dispense with the usual picking stick and
band.

E is the loom side; F slay sword; G lathe H shuttle-box; 1 crank shaft ;
J connecting rod; K cam shaft; and L the shuttle. The picker M may be
composed of sheet or other metal or other suitable material or substance; and the
end that operates the shuttle 1 may be lined with leather, compressed paper
buffalo hide, or other suitable material or substance N. The picker M is con-
structed to slide in the metallic frame or shuttle-box H. To the underside of the
picker M is attached the band or belt P, which passes over the pulley Q mounted
on the centre R attached to the lathe G. The band or belt P is attached to the
rod or arm S secured to the lever T by the bolts U. The lever T is pivoted on
the shaft or centre V mounted in the bearing or fixing W secured to the loom
side by the bolts X. On the shaft or centre V is secured the slotted lever Y
carrying the bowl or roller Z; the latter being operated by the striking piece B¹
on the cam A¹ mounted on the cam shaft K. The cam A' is provided with the
striking piece B₁ secured thereto by the bolt C' as shown in Figs. 9 and 10, which
will allow of the same being renewed in case of wear. The picker M after
operating the shuttle L is returned to its original position by the spring D₁ in the
spring-box E. The latter is secured in any convenient manner to the underside
of the shuttle-box H; and the spring D₁ is secured to the case E' and the
spindle E in any convenient manner. On the spindle E' is mounted the pulley F¹,
on which is wound the opposite end of the band or belt P. The picker M is
constructed to slide on the spindle G¹ secured on the underside of the shuttle-
box H. On the spindle Gare mounted the sliding stops H' composed of
leather, buffalo hide, or other suitable materials that will break the force of the
blow of the picker M. and shuttle 1. In conjunction with the sliding stops H¹ is
provided the sliding bar K¹ mounted on the spindle G. The sliding bar K' is
provided with the projection L which projects or extends through the slot M', in
the shuttle-box H, to the outside. To the projection L' is attached the strap or
band N, each end of which is secured to the shuttle-box H by the set screws O¹.
The strap or band N' is secured in the manner shown in Figs. 3 and 4, so that
when one end is in tension the other end is slack to allow of the next movement.
This invention operates in the following manner :-Each time the bowl Z on
the slotted lever Y is struck by the piece B on the cam A' by the rotating action
of the cam shaft K the rod or arm S is depressed, which causes the band or belt P
to jerk the picker M with such force as to throw the shuttle L through the
"shed. After the picker M has operated the shuttle L the former is arrested
by coming in contact with one of the stops H₁, the movement of the latter being
determined by the length of the strap or band N put in tension. Immediately
the bowl Z is released from the piece B' on the cam A' the rod or arm S is re-set
to its normal position by the spring D', which causes the belt or band P to be
wound round the pulley F. When the shuttle L is being operated by the
picker M the spring D' is placed in tension by being coiled round the spindle E¹,
and which assumes its normal position when the bowl Z is released by the piece B¹
on the cam A¹. To ensure of the bowl Z being held in position against the cam A¹
the boss of the lever Y is fitted with the leather or other flexible belt R' secured
thereto by the stud S. The other end of the belt R' is connected to the spiral

being secured by the nuts W
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The general arrangement, construction, and combination of parts composing
the improved picking motion for looms for weaving as herein before described and
as illustrated in the annexed drawings.
2. The metallic picker M provided with either leather, compressed paper, buffalo
hide, or other material or substance N, substantially as described.
3. The use of the spring-box E2, and spring D¹ mounted on the spindle E¹
carrying the pulley F¹ round which is wound the strap or band P for the purpose
of re-setting the picker after the shuttle has been thrown through the shed,"
substantially as described.
4. Constructing the picker M of the form shown of either buffalo hide, leather,
or other suitable material, with or without the material or substance N, substantially
as described.
