I, WILLIAM ROBERT LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particulary
described and ascertained in and by the following statement :-
This invention relates to improvements in the construction of machine made heddles;
wherein two continuous wire strands are employed to connect the upper and lower
heddle bars, or shafts, to all the eyes of a leaf of heddles, the same being constructed
complete for use by one automatic machine, that is to say, the said machine will
practically form into shape and arrange the continuous wire loops in position equally
distant apart on the top and bottom bars by means of a rubber or textile pad, or rope,
arranged in a groove along the top edge of the upper heddle-bar, and along the
bottom edge of the lower heddle-bar, so that the continuous serpentine wire loops
will not slip out of position on the top or bottom of the said heddle-bars.
Another feature of this invention is the employment of two metallic rods, arranged
one at each end of the heddle-bars; these rods are provided with a thread and nut at
each end thereof, to tighten or loosen the wire loops by extending or contracting the
space between the said bars.
.
In the accompanying drawing
Figure 1 represents an oblique side or face view of a section of a leaf of heddles;
also showing a transverse sectional end view of the bars B, B, and one of the adjusting
rods S. Also showing a series of solid eyes E, E¹, arranged upon the continuous wire
loops W, W₁, and the rope pads R, R¹.
.
Figure 2, is an enlarged face view of one of the solid metallic eyes E which are
preferably made of brass wire flattened or rolled into a thin strip.
I am aware that continuous wire loops in combination with wire eyes bent in the
fórm of a link, having an open space between the ends thereof have been employed,
but it has been found in practice, that these open links, are liable to get out of position

page_text: by the two ends of the link separating and bending outward so that they become
entangled with the thread of the warp, therefore it is preferable not to use the
link eye.
Figure 1 hereinbefore referred to, represents the bars B, B1, having a groove g, g¹,
in the top edge of the upper har B, and in the lower edge of the bottom bar B', to
hold the small ropes R, R¹, ready to receive, carry, and securely hold the continuous
wire loops W, W in their respective positions over the heddle bars B, B¹.
The machine is arranged upon a frame-work or table of any suitable length, and
the working parts are situated at the centre thereof.
The heddle bars B, B', are secured by suitable clamps in a horizontal flat position
upon the top of the bed of the machine, having their inner edges parallel to each
other so as to bring the grooved edges g, g', on the outside that they may receive the
ropes R, R¹, in their respective places ready for use; these bars when secured upon
the bed of the machine by clamps extend from the centre or working parts of the
machine to the extreme back end of the said bed. The ends of the bars B, B¹, next. the
centre of the machine are on a transverse line with each other and parallel with the
bed of the machine; and the end of each bar is secured between two brass plates
which are provided with a small anti-friction grooved wheel at one end thereof which
comes immediately over the ends of the wooden bars, so as to bring the groove in the
wheel on a line with the groove g, g', in the outer edges of the bars B, B¹, so that the
small ropes R, R', will pass over the small grooved wheel directly into the grooves g, g',
in the outer edges of the heddle-bars B, B¹, ready to receive the continuous wire
loops W, W¹.
The heddle bars B, B₁ are arranged equally distant apart so that the eyes E, E,
will be on a right line between said bars, and on a right line immediately over the
centre of the bed of the machine, so that the wire loops W, W¹, will be of equal length
when placed in position, as hereinafter described.
The small ropes R, R', are taken from reels at the back end of the machine, and
carried along the inner edge of each of the heddle-bars, to the brass plates on the end
of said bars B, B¹, the end of this small rope is passed between these plates over the
antifriction grooved wheel into the longitudinal grooves g, g', on the outer edges of
the heddle-bars, ready to receive the wire loops W, W'
The solid metallic eyes E, E, are made with a longitudinally elongated slot or
opening O, in the centre thereof, and two small circular holes r, r¹, near the points
of the eye.
'
Five hundred or more of these eyes are strung upon a thin strip of sheet metal
passing through the openings o (Figure 2), and when closely packed together are laid
on their edges in a recessed way, running lengthwise of the machine; at the centre
of the bed, in front of the working parts or gear of the same.
Two spools of fine, annealed, wire are arranged at the extreme front end of the
machine; one strand of this fine wire is taken from one spool, and another strand of
the same is taken from the other spool, and by means of a long slender needle these
wires are passed through the small holes r, r², of the whole number of eyes at the
same time, (one single wire in each hole). These loose ends of the wires after being
passed through the eyes are carried through the working gear of the machine and
secured to the brass strip at the centre of the machine.
The eyes E, E, being uniformly strung upon each continuous wire, are automatically
drawn up through the centre of the working parts of the machine until the first eye
is immediately on a line with the ends of the bars B, B¹, (which are secured between
the above mentioned brass plates), at that point a spring lever having two needle
points under the front end thereof arranged immediately over the first appearing eye,
automatically drops down so that the needle separates this first appearing solid eye
(from the following mass of eyes) then the lever rises back to its place leaving the
space open between the first and second or following eye to allow the hooks that are
arranged upon two reciprocating vertical rods on each side of the machine to auto-
matically approach each end of the eyes at the same time so that the hooks will pass
into the open space made by the separating needles, (or points) and hook on to the

page_text: wires and carry them over the ropes R, R¹, on the outer edges of the bars B, B', when
the hooks are set free from the wires by means of an excentric disc operating by a
spring between the brass clamping plates which are over the ends of heddle-bars at
the centre of the machine. The second eye comes next in line up the recessed ways
to be separated from the following mass and placed into the loop W formed by the
reciprocating hooks, and carried over and placed in position on the ropes R, R¹, this
process is continued until all the eyes are properly looped upon the outside edges of
the heddle-bars B, B¹. The ropes R, R', are gradually drawn along in the grooves g, g',
on the outer edges of the heddle-bars, as fast as the wire loops are placed upon
the same, in the manner as above set forth.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent I declare that what I claim is :-
First. A machine made heddle, consisting of one upper and one lower bar, grooved
on the outer edges; in combination with continuous wire loops, solid eyes, textile pads
or ropes, and adjusting rods, arranged at or near the ends of said grooved bars, all
constructed and arranged in the manner and for the purpose set forth.
Second. The grooved bars B, B¹, textile pads, or ropes R, R¹, adjusting rods S, in
combination with the solid eyes E, E, continuous wire loops W, W₁, formed over the
pads R, R', in the grooved edges g, g', of the said bars, and having the solid eyes
suspended in the loops thus formed, in the manner and for the purpose set forth.
