Improvements in and connected with Healds for Looms.
I, WILLIAM EDWIN HEYS of 70 Market Street Manchester in the County of
Lancaster, Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to healds for looms, and its object is to construct the
healds in such a manner that no knots nor sewing nor tieing of the yarn are
required.
According to these improvements, the healds may be manufactured from any
suitable kind of textile material, and from certain other materials such as metallic
wires, continuously, and they may be varnished in the ordinary manner coutinuously.
The spacing of the healds may be maintained by two tie-bands each of which is
constructed of two strips of fabric tissue or elastic material strongly cemented
together and holding the ends of the healds between them.
The healds are constructed of threads strands wires cords and the like doubled
twisted or plaited together except at the eye or mail where an opening is left, and
in some cases also at the ends.
The healds are preferably formed in a continuous length, the openings. being
formed therein at suitable regular intervals, and they are doubled backward and
forward between the tie-bands in which they are secured so as to bring the eyes or
mails into the correct positions.
Metallic eyelets may be inserted into the openings if desired to form the
mails.
Alternatively, each heald may be independent and have only a single opening or
eye, or they may be independent with openings or separations of the threads
strands wires or cords at each end, as for example for use with Jacquard machines,
in which case the upper ends of the healds may be secured to the Jacquard ties, and
the lower ends to the weights. If it is desired to construct the healds in the
most economical manner, they may consist simply of a system of lengths of doubled
yarns or thread, opened or untwisted at the proper points for the insertion of a
metallic mail or eye.

COMPLETE SPECIFICATION.
Improvements in and connected with Healds for Looms.
I, WILLIAM EDWIN HEYS, of 70 Market Street, Manchester, in the County of
Lancaster, Patent Agent, 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 healds for looms, and its object is to construct the
healds in such a manner that no knots, nor sewing nor tieing of the leashes is
necessary.
According to these improvements the heald leashes may be manufactured from
any suitable kind of textile material, and from certain other materials such as

page_text: metallic wires, continuously, and they may be varnished in the ordinary
manner.
The spacing of the leashes may be maintained by means of two tie bands, each
of which is constructed of two strips of fabric, tissue, or elastic material, strongly
cemented together and holding the leashes between them.
The leashes are constructed of threads strands wires cords and the like, doubled
twisted or plaited together except at the eye or mail, where an opening is made or
left, and in some cases openings are also provided at points corresponding with the
ends of the leashes. They are preferably made in a continuous length, the
openings being formed therein at suitable regular intervals, and the continuous
length may be doubled or folded backward and forward between the tie bands in
which they are secured, so as to bring their eyes or mails into the correct
positions.
Metallic eyelets may be inserted into and secured in the openings if desired to
form the mails.
Alternatively, each leash may be independent and have only a single opening or
eye, and in addition, if desired, the strands wires or cords may be opened or
separated at each end, as for example, when required for use with a Jacquard
machine, in which case the upper part is connected with the Jacquard ties, and the
lower parts with the weights. If it be desired to construct the healds in the most
economical manner, the leashes may consist simply of a system of lengths of
doubled yarn or thread, open or untwisted at the proper points for the insertion of
metallic eyes or mails.
The accompanying drawings are intended to illustrate diagrammatically in what
manner this invention may be practically carried out, and are hereinafter referred to.
In these drawings,
Figure 1 is a front view of a leash, shewn on an enlarged scale; Figure 2, a
similar view with a metallic mail inserted in the eye; and Figure 3 a side view of
Figure 2.
"Figure 4 is a front view, and Figure 5, a side view of leashes arranged between
the tie bands.
The two strands or cords A. B, which constitute the leash, may each be composed
of a suitable number of threads, doubled twisted or plaited together for the
required length. At the proper points D, this connection between A and B ceases,
leaving the open eye M, below which the constituents of the leash are again united
in a single cord. At each end of the leash, the threads wires or strands are again
separated to form the openings C, if required, and the opened and twisted or plaited
parts are, beyond these openings, again repeated. The leashes are thus, in their
first stage, parts of a continuous cord or the like, with eyes formed therein at
regular intervals, and with additional openings at points corresponding, with the
ends of the leashes, in those cases where such separation of the strands may. be
desired to form means for connecting the leashes to shafts, or to Jacquard, machine
ties and weights.
In making up the heald, the continuous length of the leashes may be wrapped
around one of the tie bands N, be passed thence to the opposite tie band N, after
being passed around which it is returned. around the first tie band, and this is
repeated until the whole number of leashes required have been arranged. Care is
taken to arrange the eyes or mails M, in their proper relative positions. The
second tie band, N₁, of each pair of tie bands is then firmly cemented upon the tie
band around which the leashes have been wound as shewn by Figure 5.
"If the separate leashes are required to be cut for making up, the ends will not be
liable to unravel or untie, as happens with existing leashes.
For the purpose of producing a still more economical.heald, doubled yarn: or
thread may be secured between parallel shafts bands strips or laces,, and at the
proper points, the strands may be untwisted or opened and a metal mail be inserted
in each opening to form the.mails or eyes, as indicated by Figure 4. This insertion
of the mails may be effected either..before or after the leashes are made, up.

page_text: Healds so made are particularly suitable for silk and other goods woven with
light and delicate warps, and they are also applicable for plain and fancy cotton
woollen flax and other goods.
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. In a heald, leashes made in a continuous length from twisted or plaited yarns
threads or wires, and having the eyes therein formed during the process of
manufacture by an interruption of the doubling or plaiting at the requisite intervals,
substantially as hereinbefore described.
2. In a heald, leashes made in a continuous length and having their threads or
strands opened and mails inserted in the openings at the proper points, substantially
as hercinbefore described.
3. A. heald for looms, having its leashes constructed and arranged substantially
as hereinbefore described with reference to the accompanying drawings.
