Improvements in Heald Shafts for Wire or Metal Healds.
I, ARTHUR BERNOULLI BARLOW, of Cornbrook Works, Manchester, in the
County of Lancaster, Wire Heald Manufacturer, do hereby declare the nature of
this invention to be as follows:-
My invention relates to those heald shafts which are composed of two staves
connected together by end pieces and adapted to carry healds formed of wire or
metal and the chief object of my improvements is to make the supports for the
metal rods capable of moving freely along the shafts in place of being fixed as now
customary so that any side pressure of the warp threads on the healds will be
sufficient to move the supports; also when the operative separates the healds for
taking up a warp thread the supports will resume their proper positions.
According to my invention I usually form each stave of the complete heald
shaft of a single piece of timber and I join these staves together by end pieces;
to cach stave is secured in any convenient manner a single piece, or two or
more pieces of metal; or in some cases the wooden staves can be dispensed with
and a single piece of metal, or two or more pieces of metal, in combination with
end pieces can be substituted to form each stave. These metal pieces are so shaped
as to form suitable surfaces for the special sliding supports which carry the rods
for the wire or metal healds.

Improvements in Heald Shafts for Wire or Metal Healds.
I, ARTHUR BERNOULLI BARLOW, of Cornbrook Works, Manchester, in the
County of Lancaster, Wire Heald Manufacturer, 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:-
My invention relates to those heald shafts which are composed of two staves
connected together by end pieces and adapted to carry healds formed of wire or
metal and the chief object of my improvements is to make the supports for the
metal rods capable of moving freely along the shafts in place of being fixed as now
customary so that any side pressure of the warp threads on the healds will be
sufficient to move the supports; also when the operative separates the healds for
taking up a warp thread the supports will resume their proper positions.
According to my invention I usually form each stave of the complete heald shaft
of a single piece of timber and I join these staves together by end pieces; to each
stave is secured in any convenient manner a single piece, or two or more pieces of
metal; or in some cases the wooden staves can be dispensed with and a single piece
of metal, or two or more pieces of metal, in combination with end pieces can be
substituted to form each stave. These metal pieces are so shaped as to form

page_text: suitable surfaces for the special sliding supports which carry the rods for the wire
or metal healds.
In the accompanying sheet of drawings-
Figures 1, 3, 5, 7, 9, 11, 13 and 14 are sectional elevations, and Figures 2, 4, 6,
8, 10 and 12 are side views of part of the upper stave of a heald shaft and sliding
support all made according to my invention.
In these views, a designates part of the upper stave 6 the metal surfaces upon
which the supports c slide, and e the rods which are carried by the sliding supports c
and upon which the wire or metal healds are threaded.
In the construction Figs. 1 and 2 a single strip of metal b is shown secured to
the underside of the stave a by screws d or other suitable fastenings, and each
sliding support c is composed of two pieces of metal riveted or otherwise secured
to a plate through which a hole is punched to receive the rod e.
The upper
edges of the pieces c are bent inwardly and form lips which bear and slide upon
the strip b.
In Figs. 3 and 4 a strip of metal b is bent round and secured to the stave a in
any convenient manner. The stave a is recessed as shown in Fig. 3 to receive the
lips on the pieces which engage and slide upon the projecting edges of the
strip b.
In Figs. 5 and 6 two separate strips b are shown secured one on either side near
the top of the stave a above which their edges project to form sliding surfaces for
the lips on the pieces c. The stave a is grooved at a¹ to receive and protect the
ends of the wire or metal healds.
In Figs. 7 and 8 in place of the two strips b as described and illustrated in
Figs. 5 and 6 a single strip of metal b is secured to the top side of the stave a to
form a sliding surface for the lips of the pieces c.
In Figs. 9 and 10 two bent strips of metal bare fitted and secured in a groove
on the underside of the stave a and the projecting edges of the strips are turned
inward and upward to form guides and slideways for a sliding piece c secured to
the plate c. The piece c can be cut away in the mid-width on each side of the
plate d to permit the ends of wire or metal healds to enter the space between the
parts of the strip b.
In Figs. 11 and 12 the strip b is channel shaped and is riveted to pins d which
are secured to the stave a. The lips of the pieces c bear and slide upon the outer
surface of the channel b the interior of which receives and protects the ends of
the wire or metal healds. In this arrangement the rod e is shown round but it
might be flat and vice versa the flat rod e shown in the other constructions might
be round if preferred.
In Fig. 13 a strip of wood or other suitable material is shown secured below
and with a thin metal strip b to the stave a.
In Fig. 14 the construction is substantially the same as that illustrated by
Figs. 1 and 2 except that in this case the parts are made and arranged for the
sliding supports to carry two heald rods e.
It will be obvious without illustration or farther description that the bottom
staves are made to correspond with the upper staves.
The staves are preferably made of wood as shown and described but they may
be made of metal or other suitable material so arranged as to furnish sliding.
surfaces for the supports which carry the heald rods to slide upon.
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 with a heald shaft having its staves furnished with metal
surfaces forming slideways, of supports for the heald rods adapted to bear and
slide upon such surfaces substantially as herein set forth.
2. The several constructions of sliding supports for the heald rods substantially
as shown on the accompanying drawings and as described.

page_text: 3. The several constructions and combinations of staves and sliding supports
substantially as herein shown and described.
