Improvements in Mechanism for Drawing-in the Warp Threads in.
Looms.
I, RICHMOND HAYWOOD INGERSOLL, of No. 15, Crescent Street, in the City of
Biddeford, County of York and State of Maine, United States of America,
Savings Bank Treasurer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:---
My invention relates to machines for drawing-in warp threads, and particularly
to a machine of this character for which Letters Patent of Great Britain, No. 17,997
and No. 3027 were granted to me respectively on the 20th day of October, 1891, and
on the 16th day of February, 1892, and my invention consists in certain improve-
ments in the mechanism for separating and holding the heddle-cords with their
eyes in the path of the reciprocating needle, whereby it is simplified and
rendered more accurate and reliable in its operation. My invention also con-
sists in supporting the warp-holding frame in such manner as to permit it to
be swung outward from the machine, whereby more convenient access may be
had to the warp-threads than has hitherto been possible, and my invention
furthermore consists in certain other novel devices and combinations of parts, as
hereinafter particularly set forth and pointed out in the claims.

The framework of the machine may be of any suitable construction, and in
the present instance consists of a bed A which is supported on suitable legs,
and is provided with guides to which is adapted a traversing carriage or slide B
which is fed from right to left by means of a feed-screw C driven from the
main or driving shaft D of the machine through the medium of suitable gearing
and other connections, not shown. The shaft D is provided with the ordinary
fast and loose pulleys, as shown in Fig. 1.
Between vertical end-pieces or standards b, b, rising from the bed A, are
secured four horizontal tubular rods upon which slide the hangers G which
support the heddles H, I, the upper and lower bars of which fit within rectangular
eyes or yokes at the ends of said hangers. J, Figs. 3, 4 and 8, represents the
reed-separating device, and K, Figs. 1 and 7, the reed which is supported in a
suitable frame secured to the standards b, b, and L is the warp-drawing needle
which is a flat steel bar pointed and barbed at its front end, said needle being
reciprocated in a tubular casing d mounted on a box or casing M secured to the
front of the carriage B, and being reciprocated by suitable mechanism, all of the
above described parts being constructed and operating in the manner fully
described in my aforesaid British Letters Patent, No. 17,997, dated October 20,
1891.
The warp-threads are wound upon an ordinary warp-beam journalled in
bearings upon a suitable stand on the floor (not shown), and said warp-threads
E

page_text: pass over an upper rod 153 a long guide bar 150 forming the upper portion of
the warp-holding frame. Over this guide-bar is pressed an inverted U or trough-
shaped spring metal clamp 151, Figs. 26 and 27, the warp-threads being con-
fined between the bar 150 and the clamp 151. The lower clamping bar 152
of the warp-holding frame is supported by a lower rod 153, and said clamping
device consists of a long flat bar 154 and a removable clamping bar 155, the
latter being held tightly in place against the face of the flat bar 154 by
removable spring metal clamps 149, the warp-threads being confined between
the two bars, and the inner side of the bar 155 which presses against
the warp-threads, being covered with felt, cloth or other suitable material
to allow each thread to be easily and independently withdrawn by the
needle L without disturbing any of the adjacent threads, this clamping_device
being substantially like that shown and described in my aforesaid British Letters
Patent, No. 17,997.
In addition to the two clamping bars or devices above described, which form
the upper and lower portions of the warp-holding frame, an intermediate or
supplementary clamping bar or device 156 is employed, composed of two,
bars 157, 158, constructed and held together in the same manner as the bars of
the lower clamping device 152, the inner side of the bar 158 being covered with
felt or cloth. This clamping device 156 is supported at a suitable distance
above the lower clamping device, and is rigidly connected therewith by means
of a series of vertical connecting bars 159 extending from one to the other, as
shown in Fig. 26, whereby when the lower clamping device 152 is adjusted
longitudinally by means provided for the purpose, the intermediate clamping.
device 156 will be simultaneously moved in the same direction, thus keeping.
the warp-threads in their proper position, this device being fully shown and
described in my aforesaid British Patents, No. 17,997 and No. 3027
The above described warp-holding frame, instead of being supported by
brackets projecting from the framework of the machine as in my aforesaid two.
patents, is supported by a swinging frame Q¹ composed of two arms 160, each.
pivoted at 161 to a base piece 162 bolted to the floor, as shown in Fig. 26.
Between the upper curved ends of the arms 160 is journalled a long horizontal
rock-shaft 163 to the ends of which are securely fastened two short arms 164
which are bolted to two lugs 165 projecting from the two upright rods.16€
which connect the upper and lower horizontal bars of the warp-holding frame
and form the end pieces of said frame. To one end of the shaft. 163 is secured a.
lever 167 by which it may be turned in its bearings to incline the warp-holding
frame at any desired angle when swung outward with the frame Q', as shown
dotted in Fig. 26, and to one of the arms 160 is pivoted a pawl 168 which engages
a ratchet-wheel 169 fast on one end of the shaft 163, whereby the warp-holding-
frame is held in position when inclined by means of the lever 167. The outward
swing of the frame Q is limited by a horizontal rod 170 extending between and
connecting the lower ends of the arms 160, said rod 170 contacting with the.
undersides of the base pieces 162, which form stops therefor, as shown in Fig. 26.
When the warp-holding frame is swung inward into its proper operative position,
it abuts against brackets 172 projecting from the frame-work A, the lever 167
enabling the frame to be brought into an exact vertical position, so as to abut
squarely against both the upper and lower brackets, as shown in Fig. 26.
By thus making the warp-holding frame separate from the framework A and
mounting it on a swinging support, so that it can be thrown back to afford
convenient access to its inner side, much trouble and inconvenience is avoided,
as the operator can stand between the warp-holding frame and the machine,
where he can easily and conveniently manipulate the warp-threads for the.
purpose of arranging the same if necessary, or reach any of the parts of said
frame which may require his attention. When the frame is thrown forward
to its operative position the opposite ends of the horizontal bars, 153 forming the
top and bottom of the frame, enter open slots 173 at the outer ends of the

page_text: brackets 172, where they are held by pins 174 passed down through holes in the
forked ends of the said brackets.
In suitable bearings at the bottom of the warp-holding frame is journalled a
long horizontal shaft 175 from which projects radially a long rib or thin bar 176
over which is pressed a U-shaped clamp 178, and between this bar and clamp
the warp-threads after passing under the shaft 175, are confined, as shown in
Fig. 26. To the shaft 175 is secured a ratchet-wheel 179 with which engages a
holding-pawl 180 pivoted to the adjacent frame. If now, in primarily adjusting
the warp-threads in the frame, it should be desired to draw them down slightly
to stretch them into a straight even position, the shaft 175 is partially rotated
in the proper direction by means of a hand-wheel thereon, the pawl preventing
any backward rotation of the shaft, and after the threads have been properly
arranged and before the machine is set in operation, the clamp 178 is removed
from the bar 176, thus releasing the ends of the threads and allowing them to
hang down freely below the warp-holding frame.
The mechanism by which the warp-threads e are successively selected and
carried one at a time against the barbed needle L into a position to insure their
being caught by its hook f as the needle is retracted so as to be drawn thereby
through the eye of the heddle and between the dents of the reed, is shown at
the right-hand end of Figs. 3 and 4, and particularly in Figs. 28 to 37 inclusive,
and will now be described.
N is a standard which is bolted to the carriage B, Fig. 4, and carries at its
upper end a table or platform 200 upon which is mounted a swinging curved
arm 30 carrying at its outer end the selecting hook g by means of which the
warp-threads are successively presented to the reciprocating warp-drawing
needle L in a manner to insure each one being caught thereby in its turn, as
will be hereinafter more particularly described.
P is a long bar extending across the back of the machine above the table 200,
said bar being supported at its opposite ends by the vertical bars 166 of the warp-
holding frame, as shown in Fig. 26. The bar P is provided with two horizontal
flanges. 203, 204, having comparatively sharp bevelled edges 205 against which
the warp-threads e are tightly pressed when stretched between the upper and
lower clamping devices of the warp-holding frame, as shown in Figs. 5 and 30,
the warp-threads being thus kept parallel and close together without riding
over each other as the table 200 is fed forward with the carriage B. In the
space between the flanges 203, 204, is placed a thread-separating comb Q extend-
ing nearly the entire length of the bar P, and capable of being moved between
said flanges in the direction of its width, for a purpose to be presently explained.
The comb Q is composed of a series of thin metallic plates 206, Fig. 37, tightly
clamped upon a long rod 207, the alternate plates being a trifle shorter than the
others, whereby shallow vertical grooves 208 are formed throughout the length
of the front face of the comb, each of the proper width to contain a single
warp-thread only, the grooves being separated from each other a distance equal
to the thickness of a single plate 206, as shown in Figs. 34 and 36, whereby
they are adapted to receive the warp-threads lying side by side against the
edges of the flanges 203, 204, as soon as the comb Q has been pushed out so as
to project slightly beyond the bevelled edges 205, as shown in Fig. 30.
During the time that the warp-threads are being properly arranged side by
side in the warp-holding frame, and stretched in place over the edges of the
flanges 203, 204, of the supporting bar P, the comb Q is drawn back so as to lie
entirely within the edges 205 of said flanges, as shown in Figs. 35 and 36, and
as soon as the warp-threads have been clamped in place, the comb Q is pushed
or projected out into the position shown in Fig. 30, when the warp-threads
will enter the grooves 208 of the comb Q by means of which they are separated
and held at a short distance apart ready to be taken one by one by the selecting
hook g which enters a long narrow slot 210 formed in the front of the comb
and extending from one end to the other of the same, the selecting hook g

page_text: traveling through this slot from end to end as the table 200 is fed forward
with the carriage B, and taking the warp-threads in succession to be presented
to the warp-drawing needle L, as will be presently described.
The comb Q is pushed out by means of a long sliding bar 212 placed between
the back of the comb and the bar P, and provided with wedge-shaped pro-
jections 213 which act against corresponding wedge-shaped blocks 214 secured
to the back of the comb, whereby as the sliding bar 212 is moved in the direction
of the arrow, Fig. 34, by suitable means, for instance, a hand-wheel engaging
its threaded end, the comb is pushed out against the resistance of springs 215,
Fig. 34, the latter serving to draw back the comb when the slide 212 is moved
in a direction contrary to the arrow.
The arm 30 which carries the selecting hook g, is pivoted to a support 201 so
as to swing laterally in a horizontal plane, said support rising from a slide 216
moving in a guideway in the table 200, and having an arm 217 which is acted.
upon by a cam 218 on a vertical shaft Y, Figs. 3, 4 and 30, whereby it is moved
in a direction to cause the hook g at the end of the arm 30 to enter the slot 210
of the thread-separating comb Q, the slide 216 with the arm 30 being moved
in the opposite direction to withdraw the hook g from the slot 210 by a
spring 219, Fig. 31, when permitted to do so by the revolution of the cam 218.
The shaft is driven from the main or driving shaft of the machine through
the medium of suitable gears and shafts, not shown.
220 is a slide moving at right angles to the slide 216 in a guideway in the
table 200, said slide being operated in one direction by a spring 221 beneath
the same, as shown in Fig. 33, and in the opposite direction by a cam 222 on the
shaft Y, which acts on a curved arm 223 secured to the slide 220, and carrying
at its outer end a vertical pin 224 which bears against the arm 30, and acts to
swing it back on its pivot in the direction of the arrow, Figs. 28 and 29,
against the resistance of a very light spring 225, the free end of which bears
against the end of the arm 30 opposite to that which carries the hook 9. The
pin 224 acts to swing back the arm 30 while the latter is being moved by the
cam 218, to cause the selecting hook g to enter the slot 210 which prevents said
hook from. coming into contact with and disturbing the warp-threads in its
backward movement. After the selecting hook has fully entered the slot 210,
the slide 220 is moved by its spring. 221 in a direction contrary to the arrow,
thus releasing the arm g which is then caused by its spring 225 to bear lightly
against the foremost warp-thread of the series, as shown in Fig. 28, as 1S
necessary to enable it to be engaged by, the selecting hook g as the latter moves
out of the slot 210.
228 is a slide moving parallel with the slide 220 in a guideway in the table 200,
and provided at one end with a hook lying in a horizontal plane, said slide 228
being operated in one direction by a spring 229, as shown in Fig. 30, and in
the opposite direction by a lever 230 connected therewith by a slot and pin and
pivoted at its opposite end at 202 to the table 200, a projection. 231 on one side
of this lever being acted upon by a cam 232 on the shaft Y. This hook h co-
operates with the selecting hook g, and as soon as a single warp-thread has
been selected by the hook, and carried out thereby in front of the comb Q, it
is caught by the hook of the slide 228 which has been previously advanced by
the spring 229 into a position to engage it, said movement of the hook / having
been effected just before the selecting-hook g commences to move out out of the
slot 210 of the comb Q, and as the slide 228 is drawn back by the cam 232, the
warp-thread is engaged by the hook and carried thereby at an angle against the
fower edge of the reciprocating warp-drawing needle L which has by this time
completed.its outward movement, and into a position to insure its being caught
by the hook or barb f of said needle L, as shown in Fig. 30, which as it is
5 retracted, carries the warp-thread back through the eye of the heddle and
through the reed, as hereinafter described. As the hook is drawn back to
carry the warp-thread against the lower edge of the needle L, the selecting

page_text: '
hook is swung back in the direction of the arrow, Figs. 28 and 29 to clear it
from the warp-thread by the pin 224 on the arm 223, and is simultaneously
caused by the movement of the slide 216, to re-enter the slot 210 of the comb Q,
as previously described, after which the arm 223 is again moved to release the
arm and permit it to be swung by its spring 225 into a position to bring the
hook 9 into contact with the next warp-thread, when the operation continues
as before.
By means of the mechanism above described, it will be seen that the warp-
threads are properly separated and presented one by one to the warp-drawing
needle with absolute certainty, and all liability avoided of the threads becoming
entangled in the mechanism and broken.
R, Figs. 3 and 6, represents the horizontal vertically reciprocating nippers
which operate to take up the slack in the warp-threads as they are presented to the
selecting mechanism. These nippers are substantially similar in construction
and mode of operation to those shown and described in my aforesaid British
Patent, No. 17,997, of 1891, and as they form no part of my present invention
they will not be herein further described.
The mechanism for separating the heddle-cords and holding them with
their eyes in the path of the reciprocating needle L in such manner that the
passage of the latter through the heddle-eyes will be insured, will now be
described, said mechanism forming the subject of my present invention, and being
shown particularly in Figs. 3 to 25 inclusive. The operation to be effected is the
same as in the machine described in my British Patent, No. 17,997, of 1891,
before referred to, that is to say, the needle passes first through the reed K,
then through an eye of the heddle H, then between two eyes of the heddle I,
Fig. 8, and after receiving a warp-thread e, draws it between two eyes of the
heddle I, through an eye of the heddle H and through the reed, but on the
next stroke the needle passes between two eyes of the heddle H and through an
eye of the heddle I, and receiving another warp-thread e draws it through an
eye of the heddle I, between two eyes of the heddle H, through the reed, and
so on, until all of the warp-threads have been drawn through the heddle-eyes
and the reed.
The number of threads which pass through cach space between the dents of
the reed corresponds to the number of heddles being threaded in the machine.
The eyes of each heddle are selected and separated one by one in proper
order, and held in position for the passage of the hooked needle L in the follow-
ing manner, and as the eye-separating mechanism for the heddle H is precisely
like that for the heddle I, the two mechanisms being so connected with the
power that the heddles are acted upon alternately, I will describe only the device
for acting on one heddle, which will apply equally to the device for acting on
the other heddle.
S, S', are two plates or platforms which are supported on posts or standards T
rising from the carriage B, and between these two platforms is a space or
channel through which the heddle-cords pass as the carriage B with the plat-
forms S, S, is traversed from one end of the machine to the other, this space
being narrowed down toward the rear end, as seen in Figs. 3, 14 and 15, to a
width just sufficient to allow the passage of one of the eyes of the heddle-cords
when said eye is turned edgewise so as to face toward the front of the machine.
At the rear end of each of the platforms S. S¹, are two small projecting
plates, m, forming jaws flush respectively with its lower and upper surfaces,
the space between the upper and lower jaws being just sufficient to hold a
heddle-eye with its upper and lower knots fitting close up under the lower plates k;
and down upon the upper plates m, as shown in Fig. 8, the distance between
the two jaws of a pair being sufficient to allow the passage of a heddle-eye
turned edgewise so as to present a single thickness of the cord only, and with its
face presented toward the front of the machine and directly in the path of the

page_text: reciprocating needle L which as it advances, is held closely up against the vertical.
end faces 50 of the platforms S, S¹.
At the corner of the platform S, which is close to the front of the machine,
is placed a guide U, Fig. 8, through which the needle L passes, said guide being
provided with a downwardly extending and inwardly inclined flange 51 which
serves to catch the point of the needle in case it should have become accidentally
sprung outward, and carry it snugly against the end face of the platform.
The heddles are constructed in the usual manner, as shown in Figs. 9, 10
and 11, and between the cords of each heddle above the eyes, passes a rock-
shaft V which is supported at its opposite ends in bearings 52, 53, Fig. 1, on the
framework. W, Figs. 9, 10 and 11, is an oscillating separating arm which is
secured to a sleeve 54 arranged by means of a feather and groove to slide on,
but rock with the shaft V, and to be traversed longitudinally thereon in unison
with the carriage B by means of carriers on the platforms S, S¹, in a manner
to be hereinafter described. At the bottom of the separating arm W on the inner
side is a rounded lip or flange n, the opposite ends of which are tapered or inclined
to meet the thin edge of the arm W, thus forming wedges 40, the purpose of which
will be presently explained.
A flattened thin edged bar 55 is as usual introduced longitudinally between
the cords of the heddles, and is suspended in any suitable manner, for instance
by means of wires, at such a height as to bring it directly under the eyes of
the heddle at a short distance therefrom, which will cause the face of each eye to
be presented toward the front of the machine. From the upper side of the
sleeve 54 projects an arm 56 carrying at its upper end a short horizontal rod or
spindle 57 parallel with the shaft V, and cone-shaped at one end, as shown at 58.
The function of this oscillating arm W and the cone-pointed rod 57 which co-
operates therewith, is to separate the heddle-cords and select eye after eye in
succession to be subsequently presented to the needle by mechanism to be herein-
after described. As the shaft V is rocked, and the arm W and rod 57 swung or
vibrated first to one side and then to the other, the cone-shaped end 58 puts a
tension on the heddle-cords lying in its path by its pressure thereon, as shown in
Fig. 10, causing the cords of the eye in advance on the side opposite to the
direction of movement of the separating arm, to slide down to the point or end
of the cone, thus separating them from those in the rear, as shown in Fig. 10,
and as the separating arm W reaches the limit of its vibration in that direction,
the thin end or point of the wedge-shaped end 40 of the lip n on that side, rests
against the knot or lower end of the eye of the next heddle on the opposite side,
as shown particularly in Fig. 11, thus holding back all the heddles on that side.
Now as soon as the arm W commences to swing back in the opposite direction, the
said wedge-shaped end 40 acting against the knot or lower end of the contiguous
heddle-eye, presses or wedges it back, thus still further forcing back all of the
heddle-cords on that side, and insuring a sufficient separation between the
heddle-cords of the eye last released and those of the eye next to come forward, to
render it certain that the separating arm will pass between them. This lip n.
with its wedge-shaped ends thus renders the action of the separating arm W
absolutely perfect, as it prevents any possibility of its failing to pass properly
between, and separate the heddle-cords, and I, therefore, regard it as a very
important feature of my invention.
I will now describe the connections between the driving-shaft and the two.
shafts V, whereby the latter are rocked to operate the two separating arms W.
To the driving-shaft D is secured a gear 60, Figs. 1 and 2, which meshes with a
gear 61 on a short shaft 62 supported on a stud 63, and carrying a bevel gear 64
meshing with a bevel gear 65 on a short vertical shaft supported in a bearing 66,
and carrying at its upper end a bevel pinion 67 meshing with a bevel gear 68 on a
short horizontal shaft 69 supported in a bearing in the framework, and carrying a
gear 70 which meshes with an intermediate gear 71, the latter meshing with a
:

page_text: The
gear 72 on a short, shaft 73 supported in bearings in the framework.
shafts 69, 73, each carry a cam-wheel 15, Figs. 1 and 7, within the groove 76
of which fits a cam-roll at the end of a vertical rod 77, which slides. in, suitable
bearings projecting from the framework. To the upper end of each of the sliding
rods 17 is pivoted a link 78, the upper end of which is connected by a pin and slot
with an arm 79 secured to the rock-shaft V, which is thus rocked at the proper
times ly the revolution of its cam-wheel 75.
The mechanism by which the oscillating separating arm W is. traversed along
its, shaft V in unison with the carriage B,- will now be described. 7, 1, are two
bifurcated carriers, each branch of which is provided at its outer end with an
anti-friction roll 80, the two branches or arms of each carrier of a pair receiving
between them the separating arm W as it is swung over to one side or the other,
said separating arm being always between the branches of one or the other of the
two carriers when swung to one side, or between the branches of both carriers
when in its central position, one of the arms W being shown in the latter position
at the right-hand end of Fig. 3. The carriers are each secured to a slide 81
moving in a groove or way 82 in the table S or S¹, and hence the separating
arms W must traverse on their rock-shafts V with the tables S, S¹, which latter
are mounted on the carriage B, as previously described.
Each of the slides 81 is reciprocated to withdraw its carrier entirely out. of
the way of the line of heddle-cords on that side by means of a lever 83 which
enters an aperture 84 in the carrier, said lever being provided at its opposite
end with a cam-roll 85, and being actuated against the resistance of a spring 86

T
A, B, Figs. 18. and 19, are a pair of double wedge-shaped slides which are
guided. in slots 108,-Fig. 22, in the platforms S, S¹, and are reciprocated simul
taneously in opposite directions by means of levers 109, 110, connected thereto:
at 112, as shown in Fig. 4. These levers 109, 110, which are fulcrumed-
respectively at 113, 114, are coupled together by a curved connecting rod 115,
Fig. 4; and the lever. 109 is provided with a cam-roll 116 which fits within a
cam-groove 117 in the face of a cam-wheel 118 fast on the shaft. 103 which
receives its motion from, the driving shaft, as previously described. Each of the
slides A, B, is composed of two members r, s, spaced apart by means of a block'
or piece t to which they are attached, said block t fitting within the slot: 108,
and the. slide having pivoted to its lower end the upper end of its operating
lever.
One side or face of each member of the slides A¹, B, is bevelled or inclined;"
and the upper and lower inclined portions of the slide A¹ are each mortised out;
as shown at 119; to receive corresponding tongues u forming the upper and lower
inclined portions of the slide B¹, whereby as the two slides are closed together,
the heddle-cords will be caught between them, and resting against their inclined
sides, will be forced outward to carry the heddle-eye between the jaws k, m, and
the heddle-cords of said. eye against the inner sides of a pair of spring-pressed
fingers,, to firmly, hold the eye in the path of the needle L, as shown in Fig. 16
and at the right-hand end of Fig. 3, said fingers being pivoted at 120, 121, to
a slide a fitting within a slot 122, Figs. 3 and 12, in the platform S: The free
ends of the two fingers v extend under and slightly beyond the inwardly inclined'

page_text: ends of two unyielding fingers 61, 6, secured to a slide d fitting within a
slot el in the platform S', as shown in Fig. 22. The slides a¹ and d' are coupled
together so as to move simultaneously in the same direction by a U-shaped
yoke D', the upper ends of which are secured to lugs 125 projecting down from the
the said slides, and to the lug of the slide, a is pivoted a lever 126 fulcrumed
at 113, and carrying a cam-roll 128 which fits within a cam-groove 129 in the face
of the cam-wheel 118 on the shaft. 103, whereby the required reciprocation is
given to the two pairs of fingers, b', and consequently with the parts in the
position shown in Fig. 16, as the fingers e, 6, are inoved from left to right after
the heddle-eye has been threaded, the bevelled or inclined ends of the fingers b
will catch the heddle-cords of this eye, and force them outward, the fingers v
yielding against the resistance of their light springs to permit the cords to pass
-out-between the ends of the two pairs of fingers into the position shown in
Fig. 17.
The operation of the above described mechanism is as follows: The parts being
in the position shown in Figs. 9 and 12, which show the heddle-cords of the
heddle H in the first position, and the line of heddle-cords being held back out of
the way by the separating arm W, the carrier g is drawn back into the position
shown in Fig. 13, which I term the second position, so that the anti-friction rolls
at the ends of its two arms will be entirely out of the way of the line of heddle-
cords on the left-hand side. The separating arm W is now swung over to the
right between the branches of the carrier into the third position, shown in
Fig. 14, the separating arm W being also shown in the third position in Fig. 10,
just previous to which the slides A', B', separate to allow of the passage between
them of the heddle-cords of the eye just released. This movement of the separat-
ing arm W releases the cords of the foremost heddle-eye on the left side, as
shown in Fig. 14, the cone-shaped end of the rod 57 at the same time putting
a tension on the cords of said heddle-eye, as shown in Fig. 10, and causing them
to, instantly separate: from those of the heddle-eyes in the rear, when they will
pass out beyond the points. of the wedge-shaped slides. A'; B, which now close
together causing the tongues to enter the mortises 119, as shown in Fig. 15,
which I term the fourth position, when the cooperating inclined or, bevelled sides
of said slides acting on the heddle-cords above and below the heddle-eye, will force
or wedge the same outward into the fifth position, shown in Fig. 16, and during
these movements the carrier q and the separating arm W return to their original first
positions, as shown in Fig. 12. The heddle-eye is now squarely between the
jaws k, m, in which position it is firmly held by the two fingers, e, which
press the heddle-cords of said eye against the opposite edges of the
slides A, B¹. The needle L now- passes through the heddle-eye, receives a
warp-thread and draws it back through said eye, immediately after which the
two pairs of fingers, 1; move to the right, when the inclined ends of the
fingers will contact with the heddle-cords, and passing behind or on the inner
side of the same, force the heddle-eye outward and beyond the path of the
needle L into the sixth or last position, shown in Fig. 17, the fingers yielding
during this movement, to permit the cords of the threaded eye to pass freely out
from between the ends of the opposite pairs of fingers, after which the heddle-
eye will pass entirely out of the jaws k, m, as the platforms S, S¹, are moved
along with the traversing carriage B. The carrier 7 in its turn is drawn
back out of the way of the row of heddle-cords on the right-hand side of the
heddle H, and the separating arm W swung over to the left between the branches
of the carrier g, to release the cords of the foremost heddle-eye on the right-
hand side, and the operation of the parts is then repeated, the slides A¹, B¹, and
fingers, b¹, acting on the heddle-cords of this eve in the same manner as on the
one last described. When the machine is arranged for threading two heddles,
as in the present-instance, the eyes of the rear heddle are all held out of the
path of the needle while a single eve of the front heddle is being threaded, and
the eyes of the front heddle are then held out of the way while an eye of the

page_text: rear heddle is being threaded, these alternate actions being continued until all
of the eyes of both heddles have been threaded. As soon as an eye of the front row
or series of cords of the heddle H has been carried into position between the
jaws k, m, and while the needle is passing through said eye, the front row or
series of cords of the other heddle I is released by the movement of its
separating finger W, and the cords of the foreniost eye of this series are permitted
to pass forward into the narrow portion of the channel i, and by the time that the
eye of the heddle H has been threaded and pushed outward by the fingers, b¹,
the eye of the heddle I has arrived into the proper position between the jaws k, m,
of its separating device for the passage of the needle threrethrough, and while
an eye of the heddle I is being threaded, the separating arm W of the heddle H
remains stationary in its central position, as shown in Fig. 9, to hold back both
series of cords, and as soon as the thread has been drawn through the eye of the
heddle I, and said eye has been pushed outward by its fingers v, 1, and while the
needle is being drawn back to carry said thread through the reed, the separating
arm W of the heddle H releases the back series of cords of said heddle, the cords
of the foremost eye of which are then carried forward, as previously described, and
while this is taking place the separating arm W of the heddle I remains
stationary, and holds back both series of cords of said heddle I, and in this
manner the two separating devices operate alternately, a front eye of the heddle H
being first acted on and threaded, then a front eye of the heddle I, then a
back eye of the heddle H, and finally a back eye of the heddle I, these operations
being repeated until the eyes of all of the cords have been threaded.
The reed-dent separator is driven from the shaft 103 by means of suitable
connections, not shown, and operates in the same manner as described in my
aforesaid British Patent. No. 17,997, dated Oct. 20, 1891, said separator making
a single revolution immediately after the needle has drawn the required number
of warp-threads through a single space between the dents of the reed.
