PROVISIONAL SPECIFICATION.
Improvements in or relating to the Shafts for Wire Healds.
We. ARTHUR BERNOULLI BARLOW, of Cornbrook Works, Manchester, in the
County of Lancaster, Wire Heald Manufacturer, and HARRY BROOK, of Crosland
Moor, Huddersfield, in the County of York, Weaving Manager, do hereby declare
the nature of this said invention to be as follows:-
The object of our improvements is first to prevent the long hooks or cross stays
from moving sideways on the metal rods of the frame, and secondly to prevent
the rods from springing out of the long hooks and out of the wood hooks which
support the rods.
The ordinary long hook is commonly made to hook over the top and bottom metal
rods on which the wire healds are strung and as the hook is free to move sideways on
the rods it is liable to cause a considerable gap between the warp threads and thus
make a reedy mark in the fabric being woven; further the metal rods are apt to
spring out of the wood hooks when ordinary long hooks are employed by which much
injury may be done to the healds.
To obviate these defects we make our improved long hook preferably of round wire
with a projecting stem at one end the projecting end of the wire fits into a hole made
for it in the heald stave; the long hook when thus put in the shaft is maintained in
one position by its extended end therefore it is not liable to cause a gap in the warp;
a further advantage of this long hook is that it tends to prevent the metal rods
springing out of their supporting hooks. These improved long hooks may be also
made of any section of metal for example the extended end and hooked portion may
be of round wire while the portion that passes between the warp threads may be
flattened. They can also be readily removed from the shafts when necessary.

COMPLETE SPECIFICATION.
Improvements in or relating to the Shafts for Wire Healds.
We, ARTHUR BERNOULLI BARLOW, of Cornbrook Works, Manchester, in the
County of Lancaster, Wire Heald Manufacturer, and HARRY BROOK, of Crosland
Moor, Huddersfield, in the County of York, Weaving Manager, 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 :-
The object of our improvements is first to prevent the long hooks or cross stays
from moving sideways on the metal rods of the frame, and secondly to prevent the
rods from springing out of the long hooks and out of the wood hooks which support
the rods.
The ordinary long hook is commonly made to hook over the top and bottom metal
rods on which the wire healds are strung and as the hook is free to move sideways on
the rods it is liable to cause a considerable gap between the warp threads and thus
make a reedy mark in the fabric being woven; further the metal rods are apt to
spring out of the wood hooks when ordinary long hooks are employed by which much
injury may be done to the healds.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying Sheet of Drawings reference being had to
the figures and letters marked thereon.
Figure 1 represents a front view and Fig. 2 a sectional end view of a heald shaft to
Prior A7

page_text: which our improvements are appliell. Fig. 3 shows 'two views on an enlarged scale of
a long hook or stay made according to our invention.
In Figs. 1 and 2 a represents the top and 'b the lower stave connected together by
metal ends e to form a heald shaft; wood hooks d support metal rods e on which the
wire healds one of which is shown at f, aro.threaded, these parts are of the ordinary
construction.
In order to maintain the staves a and b at the desired distance apart we employ our
We form
improved long hook or stays which hook over the top and bottom rods e.
each long hook or stay g as shown in Fig. 3 with a projecting stem g' at one end
which fits into a hole made to receive it in the top or bottom stave; the Drawing
shows the projecting stems g' fitted in holes in the top stave a. The improved long
hook when thus put in the shaft is maintained in one position by its extended end g
therefore it cannot move on the rods e and thus is not liable to cause a gap in the warp
and make a reedy mark in the fabric being woven further the metal rods e are less
liable to spring out of the wood hooks d when the healds are at work.
Although we have shown the improved hook g made of one section of wire
throughout it is obvious that a portion of it say between the hooks where it passes
through the warp threads might be flattened or the hook g could be formed in two or
more parts secured together.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
A long hook or stay for a heald shaft formed with a projection at one end to be
fitted into a heald stave substantially as and for the purposes herein described and as
illustrated by the Drawings annexed.
