PROVISIONAL SPECIFICATION.
Improvements in or connected with Heald Shafts and Healds
for same.
I, JOSEPH JEBSON, of 56 Firth Street, Huddersfield, Yorkshire, Commission
Weaver, do hereby declare the nature of this invention to be as follows:-
This invention has reference to heald shafts and relates to means for supporting
the healds or wires so that they shall be self adjusting.
In carrying out my invention I employ wooden shafts of the ordinary
description, and to one longitudinal edge of same I secure by screws, nails, or
similar means a tube, or bent piece of metal having a longitudinal opening or
slot on the side furthest from the shaft. The piece of metal which I preferably
use is or may be left unbent or partly bent until secured to the shaft, and then
the bending is completed so as to leave a small space between the two opposing
edges thereof. The wire healds are provided at each end with small openings,
loops, or eyelets, through which are passed rods or wires of about the same length
as the bent metal or heald shafts, these said rods being passed through the tubes
on the top and bottom shafts and supported thereby. The wires extend through
the longitudinal openings in the tubes or pieces of bent metal adapted to slide
freely on the rods in either direction and to readily adjust themselves to the
number of ends of warp and their distribution through the healds.
In thus attaching and supporting the wire healds, no obstruction is given.to
the movement of the healds in either direction from end to end of the shafts ;
the means employed are simple, easily fixed, light, and can be applied either to
new or old wooden shafts.
Stop pieces are secured to each end of the shafts to prevent the rods or wires
working out of the tubes; or instead of stop pieces, end frames secured to each
shaft may be employed. Where stop pieces are used the healds, after the ends
of warp have been threaded through them, can be bent around the warp beam
and are thus much better to carry or move about than with rigid end frames.

COMPLETE SPECIFICATION.
Improvements in or connected with Heald Shafts and Healds
for same.
I, JOSEPH JEBSON, of 56, Firth Street, Huddersfield, Yorkshire, Commission
Weaver, 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 has reference to heald shafts and relates to means for supporting
the healds so that they shall be self-adjusting.
In carrying out my invention 1 employ wooden shafts of the ordinary
description and to one longitudinal edge of each shaft I secure by screws, nails
or similar means a tube or bent piece of metal having a longitudinal opening or
D

page_text: slot on the side furthest from the shaft. The piece of metal which I preferably
use is or may be left unbent or partly bent until secured to the shaft and then the
bending is completed so as to leave a narrow space between the two opposing
edges thereof. The wire healds are provided at each end with small openings,
loops, or eyelets, through which are passed rods or wires of about the same length
as the bent metal or heald shafts these said rods being passed through the tubes on
the top and bottom shafts and supported therein. The wire healds extend through
the longitudinal openings or slots in the tubes and are adapted to slide freely on the
rods in either direction and to readily adjust themselves to the number of ends
of warp and their distribution through the healds.
In order that my said invention may be more fully understood reference is
hereinafter had to the accompanying drawings, wherein :-
Fig. 1 is a longitudinal elevation of a heald having my improvements applied
thereto, and Fig. 2 is transverse section of same.
Fig. 3 is a detail hereafter referred to.
Fig. 4 shews a modification of the means for securing the rods or pins in
position.
In the drawings a and b represent respectively the top and bottom heald shafts
and c the wire healds provided centrally with eyelets d' through which to thread
the warp. On the opposing longitudinal edges of the shafts a, b, are secured tubes
or bent pieces of metal e of about the same length as the shafts and having longi-
tudinal slots or openings fon the sides furthest from the shafts. The wire healds c
are provided at each end with eyelets or loops ġ through which are passed pins,
rods or wires which are inserted in the tubes e and supported at each end in
openings or recesses i made in the stop pieces k. The said end or stop pieces k
close up the ends of the tubes or bent pieces of metal e and prevent the healds c
working off or being accidentally withdrawn from the rods or wires h, whilst the
recesses or openings therein receive the ends of the rods or wires and support
them clear of the tube e. One of the stop pieces is removed to allow for the
insertion of the pins or rods hand healds e in the tubes e, and when this has been
done the said stop piece is placed onto the projecting end of the rod or wire and
secured by screw, nail or other means to the shaft.
Instead of stop pieces k, I may employ washers or discs m (see Fig. 4) preferably
having shoulders m' thereon which enter and engage with the inner ends of the
tubes e and support the rods or wires as shewn, the said washers or discs being
secured on the rods by pins or cotters n driven through corresponding openings
made in the rods or wires h.
When the rods or wires are inserted into the tube e, the healds c, which are
placed thereon, pass between the opposing edges of the tubes and the loops g
thereon rest upon the bottom inner sides of the tubes e which support the weight of
the healds, the latter being free to move laterally in either direction from end to
end of the shafts and to readily adjust themselves to the warp. The rods or
wires prevent the healds from twisting round or getting over the neighbouring
healds. The tubes or bent pieces of metal e are preferably first bent or made to
the section shewn at Fig. 3 in order that when securing them to the shafts the
screws and the end of the screw driver may be easily passed through the longi-
tudinal slots or openings f. When secured to the shafts the said tubes are finally
bent to the section shewn at Fig. 2 to receive the rods and healds c.
Instead of the stop pieces k or washers m, plugs m² such as shewn at Fig. 5
may be employed these being secured on the ends of the rods h by small set
screws n'.
Healds composed of worsted or cotton may be provided with loops or eyelets at
each end and used instead of wire healds.
:
The means above described are simple, light, easily fixed and can be applied
either to new or old heald shafts, or to the rectangular heald frames now commonly
used for wire healds. In the latter case the rods or wires could be supported and
secured in the frame in any convenient manner.

page_text: Healds such as herein described and shewn can be bent round the warp beam, or
doubled, and moved about from one loom to another with little trouble and without
injuring the warp or healds.
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 :-
:-
Firstly. The method of and means for supporting the healds so as to be self-
adjusting laterally, substantially as herein shewn and described.
Secondly. In healds for looms for weaving, longitudinal tubes or bent pieces of
metal e attached to the opposing edges of the heald shafts, longitudinal slots or
openings f formed in or by said tubes or bent pieces of metal, rods wires or pins h
adapted to be supported in said tubes and healds c having eyelets or loops at each
end thereof, all combined in the manner and for the purposes substantially as
herein shewn and described.
Thirdly. The combination, with slotted longitudinal tube e, rods or wires h and
healds c, of the stop piece k, or washers or discs m and cotters n or plug m
substantially as shewn and described.
