Improvements in Machines for Making Heddles for Looms.
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 particularly
described and ascertained in and by the following statement :-
This invention relates to machines for constructing heddles for looms, wherein two
continuous strands of fine annealed wire are employed to loop and hold the solid eyes
of a leaf of heddles in a vertical position, on a longitudinal right line, at the centre of
the space or opening between the bars or shafts of the heddle.
This invention consists in the construction of a machine that will automatically
arrange and hold in their respective positions all the eyes constituting a leaf of
heddles uniformly suspended upon two continuous wires and simultaneously looped
over the heddle bars so as to form two continuous sets of loops to suspend and hold
the eyes in a vertical position between said bars at a proper tension, ready for use.
In the accompanying drawings

bars e, e with their arm d', and wedge-shaped cam de, hinged to the inner end of the
said arm so that when the bar e, is moved towards the centre of the machine this
wedge-shaped point or cam do, will pass under the lever g, and raise it with its
vertical pointed bars g¹, g², freeing the same from the eyes m. Also showing the
metallic strip nn, on the ways p, immediately over the bevelled block or stop do, do,

hooks, traverse back and forth. Also showing a cross section of the pulleys d³, d³,
between the plates c¹, c¹, and ropes a², a², the hooks f, are shown in the proper
position to receive the wire loops m, as hereinafter described. f6, fe, are steel stops
at either end of the ways d. The supporting standards are shown at 1, 2, secured
to the body of the machine A.
The operation of the machine is as follows:-
The heddle shafts or bars B, B', are properly fashioned into shape having their
outer edges grooved preparatory to receiving the ropes or pads a², a², which are taken
from the reels 22, located at the back end of the machine as shown at Figure 1,

page_text: these reels are provided with any suitable device to regulate the tension of the
ropes a², a², as they are drawn from the reels ². Next one end of each bar B, B', is
fitted between the metallic cases or clamping plates c, c, then the bars B, B' are
perforated edgewise about one inch more or less from each end thereof to receive the
threaded ends of small iron rods which I term the adjusting rods, the same being
provided with suitable threaded nuts, at each end of the rods. The bars B, B', being
now completed, are placed in the position shown in Figure 1, and secured by
clamps 2, 2, and plates e, c, the two loose ends of the ropes a², a², are carried along
the inner edges of the bars B and B¹, to clamps c, c, there the ends of the said ropes
are passed around the pulleys d³, between the clamping plates c, c, from which they
are carried into and along the grooves in the outer edges of the heddle bars B, B₁,
and secured to the transverse carrying frame c², Figure 2, which frame is operated by
the carrying screw shaft q and set screw a³, Figure 1. The next operation is to
string the eyes m to any requisite number upon the metallic strip n, n; then place
the said strip n with the eyes upon the same on the ways p, p, and pass the end of the
strip n through the working parts of the machine and fasten it to the travelling bar
or frame at a², figure 12. The eyes m, are all strung upon two strands of fine
annealed wire taken from the spools o, o, at the front end of the machine, the loose
ends of these wires o, o, after passing through the small holes in the ends of the
eyes m, are also carried through the working gear of the machine and secured to the
metallic strip n, n, Figure 10.
The eyes m, m, are drawn along the ways p, by the carrying frame c², until they
are immediately under the separating points on the bottom of the bars g¹, g².
The compensating spiral spring on the strip n, Fig. 1. following the mass of eyes m,
on the ways p, holds the said eyes closely together parallel to each other in a compact
mass, as they are being drawn along the ways p.
In order to complete a leaf of heddles, the looping hooks f, f, are brought to the
centre of the machine where they will engage or hook on to the strands of fine
wire o, o, at each end of the eyes m, (Figure 1) simultaneously. This is accomplished
by the machine being put in motion so that the arms s, s, which are secured to the
revolving gear j, j¹, strike against the vertical carrying bars e, e, and carry them
towards the centre of the machine, and as they approach the eyes m, (on the carrying
ship n,) on each side, the tapering wedge shaped point de (which is secured. to the
loop carrying a standard e) passes under the lever and raise up the pointed eye-
separating bars shown at Figure 10, and allows the looping hooks to pass into the
opening left by said points, and engage the wire loops, and carry said continuous
loops back to the position shown in Figure 1.
The reciprocating arms s, s, pass through the face plate of the gear wheels j, j', so
as to be operated by the fixed circular cam k, k, and springs t, t, so that the cam will
force the rods or arms s, in contact with the upright bars e, e, while the springs set
them free, by forcing them back into the recess of the circular cam ; as the
wheels,, continue to revolve, the ends of arms s, s, are brought in contact
with a projection on the reciprocating standards e, e, at or near the foot thereof by
which means the looping hooks are carried back to the centre of the machine to
receive and carry the wire loops over the bars B, B1, by means of the segmental discs
or plates d, d, which receive the wire loops from the carrying hooks and place them
upon the ropes or pads a²; a², which distribute these continuous loops along the
bars B, B¹, in a uniform, workmanlike manner. The looping hooks again return to
the centre of the machine to perform the same functions of carrying the wires as
aforesaid until the whole number of eyes are placed in position upon the heddle
bars B, B¹.
The stretchers or adjusting rods are then placed in their respective positions at
each end of the heddle bars to regulate the tension of all the loops with eyes m,
to the desired tensile strain, this completes the operation of making a leaf of heddles,
after securing the loose ends of the wires o, to the bars B, B¹, and cutting off the
rope a².

page_text: Having now particularly described and ascertained the nature of the 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. The machine A, that will automatically form into shape, and simultaneously
place upon the shafts or bars of a leaf of heddles two continuous sets of fine wire
loops, with solid eyes, suspended within the same, all uniformly arranged over the
pads or ropes upon said bars to prevent the wires from slipping out of position, in the
manner and for the purpose set forth.
Second. The working gear j, j', with reciprocating arms s, s, operating through
sleeves or cases and through the gear j, j¹, against cam k, k, vertical bars e, e,
and looping hooks f, f, arm h, with lever g, carrying strip n, n, on the
the
ways p, following spring, and eyes m, on said ways, spools o, o, reels 12, 22,
whole operating by the main shaft r, with gears u and w² in combination with
the screw shaft q, cam x, and set screw a³, Figure 1, driving wheel w³ Figure 10.
The whole constructed, arranged and operating substantially as, and for the purpose
herein before described.
