Improvements in Looms for Weaving Two Widths of Fabric
Simultaneously.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, W., in the County of
London, Patent Agent, do hereby declare the nature of this invention (a communi-
cation to me from abroad by Louis Teweles and Thomas Arthur Robinson, both
of Paterson, County of Passaic, State of New Jersey, U.S.A. Mechanical Engineers,)
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 improvements in pickers for looms and it consists in
certain novel features hereinafter described and claimed.
In the annexed drawings,
Fig. 1 is a front elevation.of a loom provided with my improved picker, only such
parts of the loom being shown as are necessary to properly illustrate the operation
of the picker,
Fig. 2 is a plan view on a larger scale, of a portion of the raceway showing the
picker in its proper position relative thereto,
Fig. 3 is an enlarged sectional view on the line of Fig. 1, and
Fig. 4, is an enlarged detail view of the picker.
In the drawings A represents the loom frame on which the race-way B oscillates
in the usual manner, a fly shuttle 2 being thrown over said raceway by picker-
sticks a a.
To the back of the raceway is secured an upwardly extending frame C,
provided with an upper raceway D parallel with the raceway B and a suitable
distance above the same. This frame C is also provided with openings B° D° in
which are inserted reeds B' D' arranged at opposite sides of the centre of the loom
as clearly shown in Fig. 1.
The raceways B D are provided with registering longitudinal slots bd which
guide the pickers a' and the picker-sticks a, as clearly shown, and on each sides of
the reeds B D', the raceways are provided with the shuttle boxes e e¹ and ff'.
The said shuttle boxes are of different lengths and are so arranged as to almost
equal the distance from the outside ends of their respective slots to the inside ends
of their respective reeds, as clearly shown in Fig. 1.
The picker a' is secured to the picker-stick a by a leather strip and consists of
the upright arm a² provided at one end with an enlargement as partially or wholly
surrounded by a leather pad a' and at the other end with an enlargement as to which
is secured a horizontally extending arm a of a length equal to the length of its
respective shuttle box less the length of a shuttle. The free end of this arm is
provided with a crosshead a', adapted to slide on the surface of its respective
raceway, and is also wholly or partially surrounded with a leather pad a. The
upright arm a² is adapted to slide in the elongated slot d and its lower enlargement
to travel on the surface of raceway B. The vertical arm having enlargements at
its ends are connected to the picker-stick by a flexible strip or loop.
In Fig. 4, of the drawings I have shown a detail view of the picker corresponding
with the right hand side of Fig. 1. The arrangement of the picker for the left
hand side of the loom is similar, but the horizontal arm is attached to the lower
enlargement of the upright arm a² and the upper enlargement is provided with a
leather pad.
The shuttle boxes are provided with binders & connected with the loom-stopping
mechanism in the usual manner, and the warp and take-up rollers are made in
sections M M' and N N¹
In operation, the lower and upper shuttles are thrown across the loom simul-
taneously by the picker-sticks and their pickers and thereby two independent pieces
of fabric may be woven,

page_text: My improved picker is very simple in its construction and will operate rapidly
without any tendency to bind on the raceways.
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 combination of a frame having an elevated raceway, and adapted to be
secured to the raceway of a loom parallel therewith, shuttle boxes arranged on
each of the raceways, shuttles operated from said boxes, a vertical arm having
enlargements at its ends and connected to the picker-stick by a flexible strip, said
arm resting on the raceway of the loom and extending up through the upper race-
ways, a pad on one end of the said arm, a horizontal arm secured to the other end
of the same, a crosshead at the end of said horizontal arm, and a pad secured to the
end of the horizontal arm and around the crosshead.
2. A picker for looms consisting of a vertical arm having an extension at its lower
end adapted to ride on the lower raceway, a flexible loop adapted to connect said
vertical arm with the picker-stick, and a horizontal arm connected to the upper end
of said vertical arm and extending along the upper raceway.
