PROVISIONAL SPECIFICATION.
Improvements in Looms for Weaving.
We, SAMSON Fox, of Leeds Forge, Leeds, in the County of York, Civil Engineer,
and JAMES WADE, of Manor House, Wortley, Leeds, in the County of York, Engineer,
do hereby declare the nature of this invention to be as follows
This invention relates to. certain improvements hereinafter described in the
construction of lays or battons, handrails, layswords, jacks, jack-levers, breast-beams
and shuttle-boxes of looms for weaving.
Hitherto in constructing lays or battons, and handrails of looms various materials
have been employed such as wood, cast iron, a combination of wood and iron, a
combination of wood and glass, a combination of wood and leather, &c., &c., and in
order to obtain the required strength to withstand the sudden shocks vibration and
continual strain put upon such parts it has been necessary to construct them very
heavy, bulky, and somewhat clumsy; the cost of production being great.
Where solid wooden lays or battons and handrails have been used it has been
generally found that the changes of temperature to which they are subjected causes
them to warp necessitating the stopping of the loom in order that the said lay or
batton or handrail may be removed and "squared" or
"trued up, much valuable
time being lost thereby.
"
Again in the case of jacks, and jack-levers which have been constructed almost
entirely of cast or malleable iron and which in order to facilitate the shedding of the
warps have to be fitted very close together; it has been necessary to construct
them as thin as possible, and in the generality of cases they are not strong enough
to bear the strain put upon them as is clearly shewn by the number broken each day.
According to our present invention we construct the lays or battons, handrails, lay-
swords, jacks, jack-levers, breast-beams, and shuttle-boxes of looms, entirely of sheet
metal (preferably steel) pressed stamped rolled or bent (but preferably) pressed or
stamped either hot or cold to the required shape or form at one operation or by a
series of operations.
Where it is found necessary to increase the strength of the lay or batton, handrail,
layswords, jack, jack-lever, breast-beam, or shuttle-box without increasing the thickness
of the metal and where the design of such part allows, we arrange a flange either at
one side or all round as convenient; and further when it is found that owing to
limited space or from other causes, such flange cannot be employed to advantage we
strengthen the part by inserting a corrugation or embossment in any convenient part,
such corrugation or embossment increasing the rigidity of the article very considerably,
without increasing its weight.
A further advantage of our improvement is to be found in the absolute duplicity of
parts; the pressing of which enables any quantity of the same pattern to be turned
out without the slightest variation in size, and in cases where a new part is required
to replace an old one of the same size and design both made according to our
improvement it will be found that any "fitting" etc. of the same will be entirely
unnecessary; the time saved in this instance alone being very considerable.
It will be obvious that we do not bind ourselves to any particular design or
dimensions in the manufacture of the beforementioned parts which may be con-
structed of various designs and dimensions without materially departing from the
main features of our invention.

Improvements in Looms for Weaving.
We, SAMSON Fox, of Leeds Forge, Leeds, in the County of York, Civil Engineer,
and JAMES WADE, of Manor House, Wortley, Leeds, in the County of York, Engineer,
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
This invention relates to certain improvements hereinafter described, in the con-
struction of lays, or battons, handrails, layswords, and breast beams of looms for
weaving.
Hitherto in constructing lays or battons and handrails of looms various materials
have been employed such as wood, cast iron, a combination of wood and iron, and of
other material, and in order to obtain the required strength to withstand the sudden
shocks, vibration and continual strain put upon such parts it has been necessary to
construct them very heavy, bulky, and somewhat clumsy; the cost of production
being great.
Where solid wooden lays or battons and handrails have been used it has been
generally found that the changes of temperature to which they are subjected causes
them to warp necessitating the stopping of the loom in order that the said lay or
batton or handrail may be removed and "squared or trued up "much valuable time
being lost thereby.
According to our present invention we construct the lays or battons, handrails,
layswords, and breast-beams of looms, entirely of sheet metal (preferably steel),
pressed, stamped, rolled, or bent (but preferably pressed or stamped) either hot or
cold to the required shape or form at one operation or by a series of operations.
Where it is found necessary to increase the strength of the lay or batton, handrail,
layswords or breast beams without increasing the thickness of the metal and where
the design of such part allows, we arrange a flange either at one side or all round,
as convenient and further when it is found that owing to limited space or from other
causes such flange cannot be employed to advantage we strengthen the part by
inserting a corrugation or embossment in any convenient part, such corrugation or
embossment increasing the rigidity of the article very considerably without increasing
its weight.
A further advantage of our improvement is to be found in the absolute duplicity
of parts, the pressing of which enables any quantity of the same pattern to be
turned out without the slightest variation in size and in cases where a new part
is required to replace an old one of the same size and design both made according to
our improvement it will be found that any fitting, smoothing or the like, of the same
will be entirely unnecessary, the time saved in this instance alone being very
considerable.
It will be obvious that we do not bind ourselves to any particular design or
dimensions in the manufacture of the beforementioned parts which may be constructed
of various designs and dimensions without materially departing from the main features
of our invention.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view of a lay or batton and handrail.
Figure 2 is a plan of a lay or batton.
Figure 3 is a plan and Figure 4 a transverse section of a breast beam.
Figure 5 is a front view and Figure 6 a side view of a laysword.
Figure 7 is a transverse section at C. D. Figure 6, Figure 8 an enlarged section,
at A. B. Fig. 1, and Figure 9 is an enlarged transverse section of a lay or batton of
modified design all illustrative of our improvement.
a Fig. 1. is our improved lay or batton in front elevation secured by bolts to the
layswords of the loom. b is a flange on the lay or batton over which the warp

page_text: threads pass and upon which the shuttle travels, the smooth nature of the surface
enabling shuttle wheels to be entirely dispensed with, the bottom part of the reed c
fits into an embossment or corrugation in the lay or batton a and is secured thereto
by a cap and bolts h. The top of the reed is enclosed in our improved
handrail & the ends of which are extended and bolted to the layswords j.
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 :-
First. Lays or battons, handrails, breast beams, and layswords of looms, constructed
or fashioned of sheet metal, preferably steel, pressed, stamped, rolled or bent to the
required outlines, substantially as herein described, and illustrated by the accompanying
sheet of drawings.
Second. Lays or battons, handrails, breast beams, and layswords of looms for
weaving when formed of sheet metal with a flange substantially as set forth.
Third. Lays or battons, handrails breast-beams, and layswords of looms formed
of sheet metal with corrugations or embossments, substantially as set forth.
