Actuating the Shuttles of Looms for Weaving.
I, JAMES WHITAKER of the firm of James Whitaker and Company of Ingrow
Wire Mill near Keighley in the County of York, Shuttle Maker do hereby declare
the nature of this invention to be as follows, that is to say :-
Hi
>
It relates to improvements in picking-sticks or picking-arms employed for actuating
the shuttles used in looms for weaving, and consists. of, forming the outer ends of
same (said outer end being the one) to which the straps (known as the picking strap)
or bands of leather are attached, in such a manner that the strain upon said straps or
the force exerted through said straps to actuate the pickers secured thereto,.is inore
evenly distributed throughout same by which means they are. rendered less liable to
breakages and considerable wear and tear is avoided.
"
This is attained by forming each of the above named outer ends of the picking-arm
of somewhat bevelled-shape or that it shall be at a suitable angle to the longitudinal
centre of said picking-arm, so that throughout the path of motion of said arm the
strap shall lay hold thereof with its entire width and not be more tightly held on one
side than the other.
This peculiarity in the shape of the picking-arm does not interfere with the use of
same on either side of the loom or in other words it allows the positions,thereof to the
right or left hand side of the loom to be interchangeable.
•
In order to keep the picking-strap or band in suitable connection with its picking
arm as above described a strip.of metal or other material is secured to said arm and
made to overlap said strap.

Actuating the Shuttles of Looms for Weaving.
I JAMES WHITAKER of the firm of James Whitaker and Company of Ingrow
Wire Mill near Keighley in the County of York, Shuttle 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, that
is to say
It relates to improvements in picking-sticks or picking-arms employed for actuating
the shuttles used in looms for weaving, and consists of forming the outer ends of
same, to which the straps or bands of leather are attached, in such a manner that the
strain upon said straps or the force exerted through said straps to actuate the pickers
secured thereto, is more evenly distributed throughout saine by which means they are
rendered less liable to breakages and considerable wear and tear, is avoided, and by
said formation of the picking arms they (said arms) may be more cheaply produced,
since the substance (wood) from which they are made, is not required to be of any
greater calibre, at this end, than at the other in contradistinction to what is required
for arms somewhat approaching the object of this invention and of prior date.
Such being the nature and object of my said invention in order that same may be
more readily understood I have hereunto appended a sheet of drawings illustrative
thereof, to which, by figures and letters, reference is made in the following
description.
.
Fig. 1 is a side, and fig. 2 a top, view of the outer end of a picking-arm formed
and constructed according to this invention.
Figs. 3, 4 and 5 are similar views to fig. 1 but shew formations of a somewhat
modified character.
Fig. 6 is a drawing, reduced scale, shewing the picking-arm with its strap applied
thereto.
The object of my said invention is attained by forming the outer end a of th
picker-arm b somewhat of bevelled-shape as at a¹, so that throughout the path o
motion of said arm b the strap c will lay hold thereof with its entire width and not b
more tightly held on one of its sides or edges than on the other.
be som
may
The bevelled-shape of the part a may be as shewn at a¹ fig. 1 or it
what hollowed as shewn at a fig. 3 or again in addition to the straight shape shew
by fig. 1 it may be formed with a shoulder piece as shewn at d fig. 4.
In like manner the hollowed form may be used with a shoulder part as shewn 1
fig. 5, in any or each case the object of this invention being attained.
In order to keep the strap c in suitable connection with the part a as abo
described a strip of metal or other material e is secured to the part a and made
over lap the strap by spanning said outer end of the part a and being secured to s
arm bat fand g.

page_text: The peculiarity in the shape of the part a, as above described, does not
interfere with the use of the arm b on either side of the loom or in other words
it allows the positions thereof at the right or left hand side of the loom to be
interchangeable.
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
I claim is
b
A picking arm 6 having its outer end a formed as shewn and a strip of metal or
other material made to span same so that the strap c may be held substantially as and
for the purpose specified.
