the Healds to and Suspending the same from said Shafts.
1, GEORGE GATTON MELHUISH HARDINGHAM, of 191, Fleet Street, in the
City of London, Civil Engineer and Chartered Patent Agent, do hereby declare
the nature of this invention (a communication to me from the Firm of Folten &
Guilleaume, of Mülheim-on-the-Rhine, in the German Empire, Cable Manu-
facturers,) to be as follows:-
This invention relates to an improved construction of loom heald-shaft and to
improved means for attaching the healds to, or for suspending the same from, such
shafts; the present improvements being more particularly applicable to looms for
weaving cloth.
Loom heald-shafts when constructed wholly of wood are objectionable owing to
their liability to become bent or warped whilst in use; it being borne in mind that
their substance has to be kept within certain limits-three inches being their
ordinary thickness, while their length may be about two yards. Loom heald-
shafts when constructed wholly of metal are also open to objection on the ground
of their ponderosity.
The present invention is designed to obviate these objections and consists in
forming the shafts or rails of metal, preferably of I-section, and which may be
made either solid, as in the case of joist iron, or of sheet metal folded to a similar
section and stiffened, if necessary, with wooden laths. The holders for carrying
the heald-supporting rod are formed of wire so bent or arranged as to grasp two
adjacent flanges of the rail or shaft; whereby they are capable of longitudinal
adjustment ou the said rail. The holders carry eyes which may be arranged either
singly or in pairs, as the number of rows of healds demand. The healds are
threaded on the supporting rod which is passed through the eyes pertaining to the
holders; the said rod being furnished at one end with an eye which engages with
a hook-shaped projection or bolt secured to the rail or shaft. The opposite.
extremity of the said rod is straight and is passed through an eye attached at the
corresponding end of the rail. If desired, the spaces or hollows, between the
flanges, may be furnished with wood or other suitable filling; thereby imparting a
smooth surface to the rail or shaft..

the Healds to and Suspending the same from said Shafts.
I, GEORGE GATTON MELHUISH HARDINGHAM, of 191, Fleet Street, in the
City of London, Civil Engineer and Chartered Patent Agent, do hereby declare
the nature of this invention (a communication to me from the Firm of Felten &
Guilleaume, of Mülheim-on-the-Rhine, in the German Empire, Cable Manu-
facturers,) and in what manner the same is to bo performed to be particularly
desoribed and ascertained in and by the following statement :-
This invention relates to an improved construction of loom heald-shaft and to
improved micans for attaching the healds to, or for suspending the same from, such
shafts; the present improvements being more particularly applicable to looms for
weaving cloth.
Loom heald-shafts when constructed wholly of wood are objectionable owing to
their liability to become bent or warped whilst in use, it being borne in mind that
their substance has to be kept within certain limits-three inches being their
ordinary thickness, while their length may be about two yards. Loom heald-
shafts when constructed wholly of metal are also open to objection on the ground
of their ponderosity.
The present invention is designed to overcome these objections; its application
being illustrated in the accompanying drawings, whereof
Fig. 1 is a transverse section of a shaft or rail carrying holders for one row of
healds,
Fig. 2 a similar shaft or rail carrying holders for two rows of healds, and
Fig. 3 an elevation of a pair of shafts or rails with the healds arranged thereon.
Fig. 4 is a transverse section of a shaft or rail constructed from sheet metal.
The shafts or rails a a are formed of metal, preferably of I-section, and may be
made either solid, as in the case of joist iron (Figs. 1, 2 and 3), or of sheet metal
folded to a similar section, and stiffened, if necessary, with wooden laths, as shewn
in Fig. 4. The holders bb for carrying the heald-supporting rods co are formed of
wire so bent or arranged as to grasp two adjacent flanges of the rail or shaft
(Figs. 1 and 2); whereby they are capable of longitudinal adjustment on the said
rail. The holdera 6 carry oyes & which may be arranged either singly, as in
Fig. 1, or in pairs, as in Fig. 2, as the number of rows of healds d demand. The
healds are threaded on the supporting rods cc each of which is passed through the
eyes b' pertaining to the holders b. Each rod c is furnished at one end with an
eye e which engages with a hook-shaped projection or bolt f secured to the rail or
shaft a, whereby the said rods are retained in position and the displacement of the
healds prevented. The opposite extremity of each of the rods o is straight, and is
passed through an eye g attached at the corresponding end of the rail or shaft a.
If desired, the spaces or hollows, between the flanges, may be furnished with wood
or other suitable filling.; thereby imparting a smooth surface to the rail or shaft,
and serving at the same time to stiffen the same.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I olaim :-
1. The improved loom heald-shaft, constructed substantially as herein described
and consisting of a rail of I-section (such as joist-iron), or of a rail made of sheet
metal folded to assume an I-section.
2. The improved means for attaching healds to and suspending the same from
their shafts, substantially as herein described, and comprising holders, such as b,

page_text: formed of wire so bent or arranged as to grasp two adjacent flanges of the shaft or
rail, the said holders being furnished with eyes through which the heald-supporting
rods c are threaded.
3. The combination, with the heald-shaft a, of holders b having eyes 6', and
rods coach having one end furnished with an eye e for engaging with a hook fon
the shaft and the other end made straight for passing through an eye g at the
corresponding end of the shaft, substantially as set forth.
Dated this 13th day of January 1897.
