Improvements in Looms for the Manufacture of Tufted Fabrics.
1, HORACE WYMAN, of Worcester, in the County of Worcester, in the State of
Massachusetts, one of the United States of America, Superintendent, 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 for its object to improve and simplify the class of loom
represented in British Patent No. 7313, of 1886, which is an improvement on the
loom described in an earlier British Patent No. 1634, of 1881.
The first part of this invention includes a series of tuft yarn carrying needles
having their yarn receiving eyes arranged at different distances from the lower ends
of the needles and made tubular from the said eyes to their lower ends to thereby
prevent the rubbing together of the tuft yarns while the said tuft yarn needles are
being moved or selected, as will be described.
My invention also consists in a tuft yarn needle having a tubular portion to
receive the tuft yarn and provided at its interior with points to enter the tuft yarn.
the points being directed toward the delivery end of the needle to prevent the --
drawing back of the tuft yarn into the needle as will be described.
Also in a tuft yarn needle having nibs at its upper end, combined with a nib-
board having a series of bars or rods to receive against them the said nibs and
support the said needles which are to be used in the production of a row of tufts
then to be made.
Also in a series of tuft yarn needles arranged in a series of pockets, of a series of
pocketed carriages arranged side by side across the loom, and a series of parallel
tracks extended in the direction of the length of the warp, and on which tracks the
said pocketed carriages are adapted to slide under the action of eveners, as will be
described.
Also in a series of tuft yarn needles, a series of pocketed carriages, tracks
arranged side by side parallel to the warps and on which the carriages slide, and
evener carrying arms having eveners made broad enough to extend under the
needles which are not selected and dropped into position to be acted upon by the
inner edges of the eveners, so that should a second needle drop by accident in any
one carriage, it will strike upon and be stopped by the upper side of the evener, as
will be described.
Also in the combination with a series of tuft yarn needles, a series of longitudinally
sliding pocketed carriages, tracks on which the carriages slide, and a positively
actuated evener to act on the lower ends of the selected needles below the said
carriages, and arms to which the said evener is attached, of a second evener, its
carrying arms, and a spring to normally draw the last mentioned arms and their
evener toward the first mentioned arms and their evener, as will be described.

engaged by the said bars or griffs, a series of tuft yarn needles connected to the

page_text: said hooks, a hook locking board having bars to act upon a part of the said hooks,
combined with an independent bar, and means to actuate it independently of the
bars fixed to the locking frame, whereby one row of hooks may be kept from
engagement with the bars of the top board when it is desired that one row of tuft
needles connected to said hooks be operated independently of the remaining
hooks of the other rows to form a border, as will be described.
Also in a top hook board having bars to be engaged by a series of hooks, a
bottom hook board having a series of bars, and a series of hooks having eyes at
their lower extremities, shoulders above said eyes, and a guide portion substantially
as will be described above said shoulders, the shoulders being extended laterally
away from the said eyes, combined with a hook guide board to prevent the hooks
from being twisted or turned aside, as will be described.
In a loom, a top hook board, combined with a hook locking board having a series
of parallel bars, pivoted arms supporting the said board, a rock-shaft, and
connections between it and the said locking board whereby the latter may be
moved when the rock-shaft is turned, as will be described.

The frame-work of the loom, consisting essentially of the side frames A, A', A³,
mounted one on the other, (the part A' containing the chief parts of the Jacquard,)
are and may be of usual or suitable shape, said frame-work being joined by suitable
cross beams or ties.
The feed roll B to engage the carpet B₁ and feed it through the loom, the main
shaft B which in practice carries many of the operative cams, the guide or rail B³,
the carriage B sliding thereon, the weft carrying needle B attached to the said
carriage by a screw B and adapted to introduce and leave a double weft loop in the
warps as the carriage slides backward and forward in the guide B' attached to the
guide B and sustaining the carrier near its inner end, the power shaft BB having
thereon a loose pulley B over which is extended the driving belt B¹º, the hub B
having a suitable friction clutch device to engage the interior of the constantly
running loose pulley B° when it is desired to rotate the shaft B, the clutch
operating lever a, forked at its inner end and embracing an annular groove in the
hub of the clutch B, the rock-shaft a', having a handle a and an arm to which is
jointed the link a³ which connects the said arm with the said lever a so to cause
the friction clutch B" to engage with the rotating pulley B' or to be disengaged
therefrom, and the lay d², lay connecting rods, and means for moving them, are
and may be all as common in British Patent No. 1634 of 1881, to which reference
may be had.
The reed r of the lay and the tuft yarn carrying needles c, but partially shown,
are the same as in British Patent No. 7313 of 1886.
In the invention to be herein described, I have provided the loom with a suitable
shaft b, upon which is a partial gear b', shown best in Figs. 8 and 8", or a gear
having some of its teeth removed, the said gear also having attached to or forming
part of it, a flange having a concave face."
The outer or right hand end of the shaft is provided with an arm 3, shown best
in Fig. 8 which is connected, as herein shown, by an adjustable link with one
arm of an elbow lever pivoted at 70 on a part of the loom frame.
The inner end of the lever is attached by a jointed link to an arm 6ª, of an
elbow lever 60, see Fig. 8, loose on a stud 60 projecting from a stand ¹ suitably
bolted to the loom frame, the said elbow lever 6 being vibrated on said stud
whenever the shaft bis rotated.
The stud 10 outside the lever 68, 69, has loose upon it the lower end of a needle
actuating lever e, the upper end of which is jointed at c¹ to a link jointed at c³,
to the carriage B, the sum of the length of the lever c* and the link c' equalling
the distance between the centre of the stud 610 and the centre of the pivot c³ when
the carriage is fully to the right as in Fig. 84 and the needle or weft carrier 6 is
retracted from between the warps.
Viewing Fig. 84, it will be seen that the loom frame has attached to it a stand,
herein represented as having a cushion or pad c.
The said cushion or pad serves as a stop for the lever cas or just before the
carriage B arrives at its extreme outward stroke so that the centers of the joint c
between the lever and the link c³ come substantially into line between the joint c³
and the center of the stud 610.
By proportioning the lever and link as described, and providing a stop for the
lever, rebound of the lever c¹ and inward movement of the carriage on its arrival
at the end of its outward stroke is obviated.
It has been found in practice that when the sum of the length of the link and
of the lever c* is greater than the distance between the centers 610 and c³, the lever
at the end of its outward stroke is apt to rebound, start the carriage forward, and
slack the filling thread thus making imperfect selvages, or selvages in which the
filling is not drawn in and held as snugly as desired.

page_text: Ine main snart is provided with a large gear, the periphery or which is
developed in Fig. 8°.
The gear C derives its motion from a pinion C' fast on the power shaft B³, the
said pinion engaging the continuous teeth at the left of the said gear.
The gear C is shown as a broad gear, and at its right hand edge it has alternately,
as shown, three series of teeth as C, see Fig. 8º, and intermediate blank spaces C¹³,
three such blank spaces being herein shown as alternating with the three series of
teeth C², the said teeth and spaces constituting what is called a mutilated gear.
The gear has also as stated, some of its teeth removed so that the series of
teeth C in the rotation of the large gear C will come successively into engagement
with the teeth of the wheel and rotate it once and then run out of mesh
therewith.
The flange parts C³ of the mutilated gear have projecting from them locking
rims 4 which, as soon as the teeth C run out of mesh with the teeth of the gear
of 6', are acted upon by the locking flange of the gear 6', and as long as the said
flanges 4 and 6, one being convex and the other concave, are in contact, the gear,¹
and the shaft b remain at rest.
When the shaft is so at rest the weft carrier is retracted from between the warps,
the other parts of the loom at such time moving to form the shed and to take such
other steps as are necessary before the weft carrier is again inserted in the warp.
As herein shown, the shaft b makes three rotations to one of the wheel C, thus
causing three motions of the weft carrier to each rotation of the shaft. B, this being
the number of double filling threads inserted into the fabric to each row of tuft
yarns, but any other desirable number may be inserted by a proper proportioning
of the teeth of the gears C and bl.
The head of the weft carrier has a lip e which is so located therein as to come
opposite the point of the usual shuttle containing the thread employed to lock the
loop of thread laid by the weft carrier, the said lip preventing the point of the said
shuttle from catching that part of the weft thread extended from the roller e* of the
weft carrier back of the usual bobbin.
Fig. 8 shows the weft thread in position in the carrier.
The shaft B2, at the left hand end of the loom, is provided with a cam D which
in the rotation of the said shaft acts upon a lever D having its fulcrum at D2, the
said lever being connected as herein shown by an adjustable link D³ in an adjustable
manner to an arm D₁ of a rock-shaft D³ supported in suitable bearing stands Dª at
opposite sides of the loom frame.
This rock-shaft D' has fast upon it near each end, but inside the said bearings, a
dog e, and the said shaft has loose upon it two arms e', to the upper ends of which
are attached links or rods e connected at their front ends to the tuft nipper e', herein
shown as a bar having a series of teeth e at one edge, but the said teeth may be
omitted, but we prefer the teeth.
These teeth enter between the warp threads and acting against the upturned free
ends of the tuft yarns last bent down between the warp threads, aid in keeping up
the said ends while the loops made in the tuft yarns, (a weft having been inserted
in usual manner,) are being beat into place in the warp prior to cutting the said
tuft yarns off to form a row of tufts.
Should the teeth be omitted from the bar e it would act on the tufts and keep
them up but not so well as when the teeth are used, for they pass down into the
open space between the warp threads and contact with the tufts nearer the weft
about which they are bent.
Each arme mounted loosely upon the rock-shaft D' has a pin or projection
against which acts one end of a strong spiral spring which surrounds the said
rock-shaft, the opposite end of the said spring acting against the dog e referred to,
fast on the said rock-shaft, the said dog being connected thereto in an adjustable
manner by a set screw so that by rotating or adjusting the dog about the shaft the
force of the said spring may be increased or diminished.
The rock-shaft Do at the inner side of each arm e' is also provided with a

page_text: notched collar, shown best in Fig. 8 at the right, where the carpet is broken
out, a shoulder of the said collar being acted upon by shoulder of the said arm e' to
limit or stop the forward movement of the arm e due to the spring h, toward the
reed r, the latter having dents and being as in the Patent referred to, or as in any
usual loom for weaving tufted carpets.
The tuft nipper acts as an auxiliary to the reed and cooperates with the dents
of the usual reed to hold the tuft yarn in loop form between them as the said yarn
is being made into tufts.
The tuft yarn carriers or needles are fully lowered between the warps while the
reed is at its back stroke, and at this time the tuft yarn nipper or clamping bar
occupies a position beyond the cloth making point for about the distance more or
less between the cloth making point and the dents of the reed and in such position
the said bar acts to arrest and support the free ends of the tuft yarns extended from
below the eyes of the tuft yarn carriers or needles through between the warp
threads.
At this time the point of the weft carrier stands near the selvage ready to enter
and lay a weft between the open shed and across the ends of the tuft yarns, such
weft acting as the tuft locking weft to hold the tufts in the fabric.
The double or loop-like weft, having been passed through the open shed, is
locked at the opposite selvage by a thread carried by a small shuttle, as in the
Patent referred to, and the weft carrier is then retracted, the reed, the needles,
and the tuft nipper bar remaining stationary while the weft is being laid as
described.
As soon however as the tuft weft carrier is entirely retracted from between the
warps, the said needles commence to rise and are lifted until their points are
elevated above the warp and above the range of movement of the reed when the
latter starts forward toward the fell and at about the same time the tuft nipper
bar e is moved toward the advancing reed r, the points e10 of the said bar then
standing in the spaces between the warp threads and act against the short ends of
the tuft yarns, and the reed and the bar continue their movement toward each other
until the tuft yarns then bent into loop form are caught between the reed and tuft
nipper, and thereafter in the further forward movement of the reed the lay acting
upon the said nipper pushes the latter back against the stress of the springs h, the
said reed and nipper clamping and holding the said tufts firmly while the reed beats
the weft. then holding the tuft yarns bent about it, firmly in at the fell, after which
the reed again commences to move backward away from the fell and the tuft nipper
by a movement of the rock-shaft D' is retracted to get out of the way of the cutting
mechanism which is to sever the tuft yarns and complete a row of tufts, and the
nipper bar having been retracted and at the same time another shed having been
formed, the weft carrier is again thrust through the shed and retracted leaving a
weft which the lay in its next forward movement again beats in behind the tuft
yarns, all as provided for in the said Patent.
Viewing Figs. 8 and 8' it will be seen that the tuft nipper or clamping bar e has
a heel 100 which as the said tuft nipper is pushed toward the roll B by the reed
strikes a cam 102 which causes the tuft nipper to be elevated, as shown in Fig. 8,
to thus draw the acting teeth or edge of the nipper from the pile.
The lay having been moved fully forward, the tuft yarn cutters, not shown but
common to the said Patent, complete their movement, and cut off the tuft yarns
leaving a row of loops, the said yarns being cut off when the lay is fully forward,
and just before the cutters act to sever the tuft yarns the needles are raised slightly
to pull off enough yarn for another row of tufts.
The tuft yarns having been cut off, the cutters will separate, the lay will be
moved back, and the tuft yarn carriers being elevated all into the same plane and
selected according to color as provided for in the said Patent, the shed will again
be formed and the weft carrier be for a third time inserted through the shed and
retracted.
During the time that the weft thread carrier is being so retracted, the needles

page_text: next to be employed for the next row of tufts will be dropped and the tuft nipper
bar will be moved forward substantially into the position shown in Fig. 5, and the
carriages containing the tuft carrying needles will be evened, and the lay will beat
in the third shot of filling, and recede and the tuft yarn carriers will again be
lowered and moved downward diagonally toward the rear of the loom passing the
tuft yarns through between the warps into the position from which the description
was started.
The lever which is mounted loosely on the stud 610 is connected to an arm of
the lever by a spring pin or locking device 103 so that when the said locking
device is disengaged, the loom can be run without actuating the lever * to correct
mispicks or for other purposes.
The tuft yarns t, shown partially only in Figs. 5, 6 and 7, will come from
suitable spools or bobbins mounted in a creel frame at the rear of the loom, and
that the loom will be provided with usual and suitable shed forming devices to form
sheds in the back or foundation warps which may be composed of cotton, jute, or
other strong, material; and that the loom will be provided with two or more warp-
beams, suitable whip-rolls, and tension and let-off mechanisms; and with means
for rotating the roll 42, which will or may be provided with suitable pins to enter
the carpet or fabric and take the same up as woven; and these devices are and
may be substantially as in the Patents referred to, and, therefore, it has not been
considered necessary in this present instance, to show any of the said parts or
devices, but only to show the different parts herein to be claimed together with
such parts common to the said looms which are changed or modified in construction
to actuate the said novel parts.
The shipper shaft a¹ has a shipper handle a², see Figs. 2 and 94, provided with
a pawl a acted upon by a spring a", the said pawl having a projection at its lower
end adapted to engage a notch a2 in a stand a23 when the shipper handle a' is in
the position shown in Fig. 8, the parts of the friction clutch pulley at such time
being disengaged and the loom at rest.
The link a is jointed to the arm a of the rock shaft a¹ in such manner that
when the handle a is thrown over to the left in Fig. 8 or to the right viewing
Fig. 94, against the stop a, the center of the joint between the arm a and the
link a³ will fall below the horizontal center of the shaft a', thereby keeping the
handle a in that position and the clutch parts closed to run the loom.
The shaft a' has loose on it between two collars a, see Fig. 2, the hub of an
arm which is connected by a link a" to a vertically movable slide rod ao, shown
also in Fig. 3B and partially in Fig. 9B, the lower end of which is extended loosely
through a guide stand a secured to the frame-work, the said slide rod being
surrounded above the said stand by a spiral spring a³, the lower end of which rests
upon the said stand while the upper end of the said spring acts against a collar a
secured to the said rod, the said spring normally acting to push the said slide rod,
as shown by dotted lines Fig. 93, upwardly against the shank of a block a", shown
separately in said fig., the said shank being adapted to slide horizontally in a
stand a secured to the frame-work.
The shank of the block a has a hole in it, as shown in Fig. 9B, for the reception
of rod ao, the dotted lines showing said rod in said hole, and the block has an
opening a, through which are extended several legs to be described, constituting
parts of several stop motions.
The block a is normally pressed inwardly by a spring a, and in such position
the upper end of the slide rod a acts against the underside of the said block, as
shown by full lines Fig. 9B and the spring u" is compressed.
Whenever however, the block a" is pulled outwardly, as will be described, then
the hole in the said block comes in line with the said rod a0 and the latter is
permitted to rise under the action of the spring a" and enter the said hole, and
said rod through the link a connected to the arm a causes the shoulder 40 (see
Fig. 3B) of the said hub to act against the shoulder of the collar a27 fast on the
B

page_text: shaft a', and turn the same in the direction to disengage the clutch part B12 of the
clutch pulley from the part B and stop the loom.
Providing the hub of the arm a28 and the collar a with shoulders as described
and mounting the said arm on the shaft a' loosely, enables the shaft a to be
operated by the handle a² to release or clutch the clutch pulley parts together as
desired without moving the slide bar a³0.
The loom frame has a suitable stand at 10 in which is mounted a rock-shaft 612
(see Fig. 2) having an arm 613 which twice during each rotation of the power
shaft B, is acted upon by the cam projections 4, (see Fig. 37) of the brake
wheel attached to the said power shaft B8.
A spiral spring 61 connected to an arm of the rock-shaft and to a suitable
stand on the frame-work normally acts to keep the end of the arm &¹³ in the range
of the said cam projections 614.
The opposite end of this rock-shaft 6" has an arm or vibrator which vibrates
close to the underside of the head of the block a so that whenever the ends of
. either of three legs, to be described, is permitted to descend below the head of the
said block, the said vibrator will strike it and pull the block a outwardly against
the spring, permitting the hole in the shank of the said block to come in line
with the rod a to enable the latter to rise and the shaft a¹ to rock to stop the
loom as described.
The leg 6 shown in Fig. 2 and partially in Fig. 9 forms part of what is called
the shuttle stop motion.
This leg has its upper end turned down to enter the opening a of block a at
its end nearest the front of the loom, and when the said leg is in its normal position
and the thread in the selvage shuttle is being properly delivered, the said down-
turned end stands above the bottom of the block a³4.
The lower end of the rod 18 is jointed to an arm 21 of a rock shaft 2 extended
across the loom frame and provided at its opposite end, see Fig. 20, with an arm 623
which has attached to it a link which in turn is jointed to the lower end of the
selvage shuttle thread controller pivoted at 628 on a suitable stand 627, the upper
end of the said controller, being vibrated between the selvage of the cloth at
that side of the loom and the inner side wall of the selvage shuttle race 628 which
is bolted to a suitable fixed part of the loom.
The shuttle race is arranged in the arc of a circle aud contains the selvage
shuttle 629 which is actuated by a shuttle carrier having usual horns, such as
commonly employed on carriers for moving sewing machine shuttles, the said
carrier by its horns passing the shuttle through the loop of weft thread carried
through the shed double.
The shuttle carrier, see dotted lines Fig. 20, and detail Fig. 38, is connected by
a link to an arm 60 of an elbow lever pivoted at on a suitable stand, the
opposite end of the said elbow lever being connected by a link
of an elbow lever 83 which is acted
shaft B near the left hand side of the loom.
by a suitable cam
to the upper end
fast on the cam
normally acts to keep
A spring connected to the said lever and to a hook
a roll or projection of the said lever against said cam.
The rock-shaft 62 referred to, near the right hand side of the loom, has connected
to it an arm, shown chiefly by dotted lines Fig. 2 to which is jointed a rod 6,38,
see Fig. 1, connected to one end of a lever 689 pivoted upon a stand 640, the opposite
end of the said lever having a roller or other stud which is acted upon by a cam 1
fast on the cam shaft B2 just within the frame-work near the right hand side of the
loom, the cams 634 and 64 being shown separately in Figs. 34 and 35, the said cams
having three points so as to move the parts actuated by them once for every pick
of filling inserted double into the fabric.
The spring 6 connected to the lever 60 causes the upper end of the said thread
controller to move toward the center of the loom and act upon the selvage shuttle
thread to take up any slack therein, and in case the said shuttle thread breaks, the

page_text: shuttle thread controller continues its movement sufficiently far under the
action of the said spring to further turn the rock-shaft 622 in the direction to cause
the down-turned end of the leg 18 to descend below the block a", so that the
vibrator catches it and effects the stopping of the loom.
The shape of the cam which acts on the lever is such that it acts inter-
mittingly to throw the thread controller toward the front of the loom, the
spring normally acting to move the said controller toward the center of the
loom to act on and take up the slack in the shuttle thread.
The movement of the controller 25 due to the spring 67 is stopped by the thread
as soon as the slack is taken up, and the thread then acts to prevent the spring "
from moving the lever far enough to enable the roller at the inner end of said
lever to enter the bottom of a space between the throws of the cam 61, see Fig. 35
but in case the thread breaks, the spring 7 has full control of the controller and
moves the same sufficiently to draw down the leg 18 and effect the stopping of the
loom, as described, the roll at the end of the lever ¿ then bottoming in the lowest
part of the cam 641.
The selvage shuttle thread controller 63 also by its action upon the shuttle thread
keeps the said thread so taut that the loop or filling through which it is passed
when the said loop is being drawn back and properly tightened in the fabric, does
not draw in the selvage shuttle thread within the regular selvage threads of the
warp.
The loom frame has applied to it a suitable stand co, see Fig. 25, having a
spring which bears upon the filling thread ft, it coming from a suitable can or
bobbin, not shown, and going to the usual filling thread carrier or needle, not
shown.
The filling thread just beyond the spring referred to, receives upon it a hook or
eye c¹³ of a rod pivoted at c¹ and having a leg ¹ which is also extended down
through the hole as in the block a, and in case the filling thread breaks the said
leg is permitted to drop sufficiently below the said block to be caught by the
vibrator 7, so as to pull out the said block a³ to stop the loom, as before
described.
The third stop-motion which is made effective through the vibrator 6" described,
acts when two tuft yarn carriers are dropped at the same time between the open
eveners.
This third stop-motion contains the leg c¹ described, which is extended upwardly
through a guide in a stand e" attached to the loom side, the said leg having a lug
or projection c¹, see Fig. 9, at its inner side, which is below the said guide, the
said projection resting upon an arm c¹³, see Fig. 3, attached to a rock-shaft 20
having bearings in the said stand, the said rock-shaft having a second arm, see
Fig. 5, which is adapted to be acted upon by an arm 2 connected to a rock-shaft 23
having its bearings in the side rods 120, the said rock-shaft 23 having a like arm
near each side of the loom.
The rock-shaft 20 has an arm acted upon by a spring to normally cause the
arm to keep the leg elevated so that its lower end does not protrude below the
bottom of the block a³.
The eveners 146 and 146, to be described, which act on the lower ends of and
align the dropped or selected tuft yarn carriers c, are connected to the lower ends
of arms 25 and 25* pivoted on studs 145 and 145³ carried by the rods 18 of the
swing or lift frame to be described.
C
The arms 25 have each an upward extension 153, which in case two tuft yarn
carriers or needles a should happen to be dropped at the same time in any one
carriage so as to prevent the evener 146 from remaining in its normal acting
position by the action of the spring 147, will cause the said extensions 153 to act
upon the described arms and push them out or back in the direction of the arrow
near one of said arms in Fig. 5, so that when the swing frame which raises and
lowers the tuft yarn carriers descends to cause the lower ends of the selected needles c

page_text: to be entered between the warps, the said arms will strike the arm c² of the
rock-shaft c, and turn it far enough to permit the leg c¹ to drop with its lower
end below the block a to be struck by the vibrator to stop the loom as before
described.
The evener 146 has to move many carriages and needles, and the strain on it is
at times considerable, and if the rock-shaft 23 should have an arm at but one
end, so that the shaft 3 could be turned only at one end, the springing of the eveners
might render the third stop motion uncertain, so to do away with this uncertainty
the shaft 23 has two arms cone near each end.
The shaft a' has an arm 14, see Fig. 2, which is connected by a link do with one
end of the brake lever pivoted at d", the said brake lever having a suitable
brake d¹ which when the shaft a¹ is turned to release the clutch pulley also causes
the said brake to be forced against the periphery of the brake pulley 1,16.
The top board E (shown in Figs. 3, 4, 10, 14 and 18) provided with a series of
longitudinal griff bars 100 has at its opposite ends ears 117, which are suitably
bolted to carriages E' suitably shaped to slide in the end slots 118 of the Jacquard
frame-work A
These carriages have studs 101 which receive upon them metal loops 119, see
Fig. 10, into which are screwed the upper ends of rods E2, the lower ends of which
rods are screwed into joint blocks 120, see Figs. 5 and 9, (and by dotted lines in
Fig. 3), the said joint blocks being pivoted between the bifurcated ends of radius
bars 121, pivoted at 122, on the loom side, said radius bars acting chiefly as guides
to control the lower ends of the joint blocks in their vertical movement.
The ear at the lower end of each joint block, there being one at each side the
loom, has bolted to it at e¹ the upper end of one of the like side bars 18, of the tuft
yarn carrying swing or lifting frame, the lower ends of the said arms being jointed
at 14 to the upper ends of the arms e³, common to British Patent No. 1634, the said
arms being adapted to slide vertically in grooves at the inner sides of the arms es
pivoted at es in stands e¹8 attached to the frame-work.
These arms and the slides e³ are substantially the same as in the said Patent
and are actuated by substantially like means under, however, slight modification.
In this instance, the arms e derive their backward or forward movement once
during the insertion of each three double picks of filling, by or through a tubular
rock-shaft e surrounding the shaft, the said rock-shaft near each end having like
arms which have attached to them at their upper ends rods which are
connected to the upper ends of the arms e8, the said rock-shaft having an arm e
provided with a roller or other stud which is acted upon by the cam e¹ (see
Fig. 30) on the main cam shaft B' of the machine.
The slide bars es have attached to them at their lower ends, links f which are
jointed to arms 125, pivoted at 126 upon arms f³ attached to the rock-shaft f, the
said arms having slots, as shown in Fig. 1, to receive bolts, 126, attached to the
arms 125, to thereby permit the said arms to be adjusted on the arms f³ and enable
the exact positions of the top-board and all parts which move in unison with it to
be determined as to their highest and lowest positions.
The rock-shaft ƒ has an arm f which is acted upon by a cam f, there being one
such arm near each end of the rock-shaft and one such cam near each side frame of
the loom so as to lift the arms e³ and the parts above it equally at both sides, the
said cams being denominated the heavy lift cams.
The rods E referred to forming part of the said swinging and lifting frame,
having secured to them by set screws 114, the hubs 113, to which is suitably bolted
the needle guide board E, the said guide board having (see Fig. 18) a series of
parallel bars 134, and a series of transverse wires 115, so located with relation to
each other as to receive the broadened looplike ends of the hooks G to be described
and prevent the said hooks from twisting or partially rotating so that their upper
ends 135 will not be properly caught at the proper times on the griffs 100.
The top-board E has suspended from it by links 102 (being best shown in Figs. 10

page_text: and 14) a hook-locking board E, the said links being bolted by bolts 103 to ears 104
of said frame.
This frame has a series of longitudinal bars 110 and a series of transverse bars 112,
see Fig. 15, thus making spaces for the reception of each hook G.
One of the links 102 is connected by the link 105 to a short arm 106, shown by
full lines Fig. 10 and dotted lines Fig. 14 of a rock-shaft 107 extended across the
loom frame, the said rock-shaft having an arm 106, to which is jointed a hand
rod 108, extended down within the reach of the operator at the right hand side of
the loom, so that the operator by pulling down upon the said rod may move the
locking frame E³ from its position Fig. 18; in the direction of the arrow in said fig.,
such movement taking place however at a time when all the needles are lifted by
the hook-lifting board F, at which time the upper ends 135 of the hooks are above
and clear of the griff's 100.
The movement of the hook locking board in the direction stated, causes the
bars 110 carried thereby, to act against the hooks G and press them aside in such
position that when the top-board is again lifted, the griff's engage and lift all the
books acted upon by the bars 110; and while the locking frame remains in such
position, the top-board is raised and lowered, taking with it all needles or carriers
connected to the hooks which are kept on the griffs, but said needles or carriers are
not lowered far enough to enter their yarns into the shed and form tufts.
While the tuft yarn carriers or needles are so raised and lowered but do not make
tufts, the usual harness frames, not shown, but common to British Patent No. 1634,
and to usual tapestry carpet looms, shed the jute or backing warp, and together
with the filling inserted double, a heading or untufted portion is woven.
During this operation the hooks held by the griff's cause the Jacquard needles to
be thrown in and out of the range of the cards of the Jacquard needles so that the
said needles are not reciprocated.
I have omitted from the locking frame, bars 110 to act on the first and last row
of hooks, for at times it is desired to weave a border with one or more rows of
needles lifted as a bank by the lower hook board F.
To enable this to be done when desired with say the row of needles nearest the
breast beam, the stands 136 supporting the rock-shaft 107 receive a rock-shaft 137
having two or more arms 138, see Fig. 14, to which is attached a bar 110*.
The shaft 137 has an arm 139 to which is jointed a hand rod 140 extended
down near the left hand side of the swing frame 18, the said rod having a suitable
collar or collars 410 to rest either above or below a catch stand 412 attached to the
swing frame below the joints of the levers 25, 25*.
By pulling down on the hand rod after disengaging it from the catch stand, the
bar 110 controlled by it may be placed in condition to act on the first row of
hooks and throw them into position to be engaged by the griff next to them, while
the bars 110 of the locking frame act to keep the other rows of hooks on the griff's
and then a heading will be woven.
In case however that a border is to be woven, then the hand rod 140 will be
disengaged from the catch standard and pushed up so that the bar 110* carried by
the arms 138 of the rock-shaft 137, will not strike against the row of hooks next
to it when the locking frame is moved aside as described, and the first row of
hooks will remain with their shouldered lower ends on the lower lifting board F, to
be raised as a bank, the first row of needles or carriers inserting the tuft yarns
carried by them into the sheds and forming rows of tufts.
In like manner the bar 110** for the rearmost row of hooks has been attached
to arms 138* of a rock-shaft 137 in brackets 136, the said shaft having an
arm 139* and an attached hand rod 140* provided with a suitable collar or collars
to cooperate with the opposite end of the catch stand 412 to that which is engaged
by the hand rod 140.
By moving the rock-shaft 137 in one direction, its bar 110** will cause the
hooks next to it to be all caught by the griff's with which they cooperate, and in

page_text: the other direction the said hooks will be permitted to fall with their shouldered
ends on the lower lifting board F to be worked in banks.
The hand rod 108 of the rock-shaft for moving the locking board will have a
catch stand 450, see Fig. 40.
Fig. 41 shows parts of the rods 140 and 140* and the catch stand.
The arms 18 of the swing frame referred to have bolted to them suitable
stands 141 which support the inner ends of the nib board H, the said nib board
(see Fig. 6) having a series of longitudinal rods 141, and a series of transverse
bars 142 to thus divide the interior of the said nib-board into small spaces, one for
each tuft-yarn carrying needle c, the said needles each having near its upper end
above the said board, a nib 143, which nib when any needle has been selected so
that it is dropped in order that a tuft may be made from its yarn, will strike against
one of the transverse cross bars 142, said bars thus serving to support the weight of
the needles.
Erected upon the ends of the nib board (see Fig. 9) are like stands 144, to the
upper ends of which are suitably secured the lower guide board H for the tail
cords G', the joint e¹7 before referred to about which the upper ends of the arms 18
of the swinging and lifting frame turns, being located substantially or nearly in
line with the said lower guide board, instead of at a considerable distance below the
said guide board as in the British Patent No. 7313 of 1886, referred to, for it has
been found that by elevating the said described pivotal point ", as described, wear
upon and consequently cutting of the tail cords into the lower guide board, is sub-
stantially done away with, and as such wear is a very serious detriment in the
operation of the Jacquard mechanism this elevation of the said pivotal point
becomes an element of importance.
The arms, 18, each have two like studs 145 and 145, upon which are pivoted
the evener carrying levers 25, 25, provided at their lower ends respectively with
like eveners 146 and 146, the said eveners instead of being simply round rods, as
in the British Patent No. 7313, referred to, being made as broad flat plates to stand
underneath all those needles which are not selected and dropped, so that in case any
tail-cords should break and a needle not wanted should drop, it will rest upon the
evener below it.
The evener lever 25 has connected to it a spring 147, the opposite end of which
spring is connected in a suitable manner to a stand 147* attached to the other evener
lever 25, see Fig. 5, the said spring normally keeping the lever 25 pressed against
a suitable stop t, see Fig. 54, forming part of the stands p, bolted at p¹, to the
arms 18 the said stands having wings 151.
The inner edge of the evener 146 carried by the levers 25 always stands normally
in one position, but the said levers 25 may be moved toward the front of the loom
by or through the action of the evener 146* carried by the arm 25* acting against
the dropped needles, and so also when it is desired to gain access to the needles and
carriages, to be described, the arms 25 may be engaged by hand and turned out-
wardly toward the front of the loom, where they may be retained by reason of
dogs 149, see Figs. 5 and 54, pivoted upon the said arm 25, which dogs engage
projections 150 of the said wings 151 connected to the said stands p.
The ends of the ears 151 have lugs 405, see Fig. 54, which receive screws 406
see Fig. 5 which screws fasten to the said wings a cap plate 151, see Figs. 5
and 9.
The levers 25 have jointed to them, connecting rods 25" in turn jointed to the
upper ends of levers 25° adjustably connected by bolts 25° to a web 25ª, of a
tubular shaft 25° surrounding loosely the lay actuating shaft h20, the said tubular
shaft having an arm 25' provided at its lower end with a roller or other stud which
enters a cam groove 258 see Fig. 29, at one side of the evener actuating cam 25",
fast on the cam shaft B'.
The stands p have at their lower ends horizontal extensions t³, and to the
ends of these extensions are bolted the opposite ends of cross bars t* provided with

page_text: a series of notches in which are laid a series of tracks H' composed of thin steel
plates.
One of these tracks is shown in section in Fig. 7°, each of the said tracks serving
to receive upon it and support one of the carriages H', each having a projection
near its upper end to rest upon one of the said tracks, the carriages, equal in
numbers to the tufts in each transverse row of tufts being adapted to slide upon the
said tracks as will be described when the eveners act upon the selected or dropped
needles c to align them.
The carriages are also adapted to be moved backwardly away from the breast
beam after each tuft pick by the action against the other end of carriages of the
carriage evener bar H, see Fig. 9, connected at its ends to arms H7 jointed to the
lower ends of the evener levers 25*.
Each carriage has a series of pockets, see Figs. 7 and 7B, to receive the lower
ends of the needles c, the said carriages each having a series of pockets corre-
sponding to the number of longitudinal rows of needles employed, as for instance, in
practice there may be from six to ten needles standing in front one of the other in
the direction of the length of the arms t³, and there will be as many needles in each
transverse row of needles as there are tufts to be inserted in each transverse row
of tufts.
The carriages slide freely on the tracks referred to and the eveners act upon the
lower ends of the tuft yarn carriers c which are selected for the next row of tufts to
be made to align them across the warp, the said carriers at such time being dropped
below the said carriages by the descent of the lower lifting board upon which rest
the lower ends of the hooks G connected with the said carriers so to be used.
Mounting the carriages upon the tracks so as to slide thereon, instead of
providing the carriages with extensions to slide in the said groove, as has been
done, adds to the compactness of the parts of the loom.
It will be understood that the tuft yarns t taken from suitable spools or bobbins
directly to the eyes of the needles, are led down through the said needles and out
from their lower ends, each needle being provided, as best shown in Fig. 7, with
one or more holding or retaining devices, said devices being herein represented as
points 152, so arranged and directed as to enter the tuft yarnt and prevent it being
drawn backward into. the needle, but I do not intend to limit my invention to the
exact form of holding devices shown.
The needles are also provided with openings at their edges near their delivery
ends, see Fig. 7, to enable the tuft yarns to be asily threaded into the needles.
It will be understood that the top board, the controlling board, the hook guiding
board, the nib board, the lower guide board H¹ and the carriages, their tracks and
supporting devices, all rise and fall in unison, they deriving their vertical movement
from the heavy lift cam referred to.
The arms 25 have jointed to them at their lower ends, arms H' connected to a
carriage evener bar or rod H° which crosses the loom in front of all the carriages,
so that when the arm 25* is moved toward the rear end of the loom, the said bar by
acting upon all the carriages will push them back into their normal position upon
the tracks, and in this position of the carriages the tuft yarn carriers will be
selected, as will be described, and those carriers which are to be used in the next
row of tufts will be permitted to descend below the carriages, the arms 25 at this
time being arrested by their stops 2, and thereafter the evener 146* attached to the
arm 25 will be moved toward the selected tuft yarn carriers or needles c and
will carry them all forward against the evener 146, which is held in position by
the spring 147, but in case two carriers c have been dropped in one carriage the
evener 146 will receive an extra motion and cause the extension 153 to stop the
loom as described.
The arms H' have attached to them at the opposite sides of the loom, springs 410,
the opposite ends of which are attached to pins or projections of the stand p
attached to the swing frame 18, and the said arms have projections which

page_text: when they are fully lifted by the spring act against stops 422 carried by the
levers 25*
These springs normally hold the bar H up so as to act against the ends of the
carriages, but in case it is desired to remove a carriage or draw it out more or less
to gain access to the tuft yarn carriers therein, then the levers 25 are pulled out by
hand from the front of the machine and the arms H' are depressed sufficiently to
place the bar H below the lower ends of the carriages, so that the latter may be
pulled out.
The rods E' are screw-threaded for some distance near their lower ends and
receive upon them adjustable lifting nuts 154 see Fig. 10.
Interposed between the hook guiding board E and the lower tail cord guiding
board H is a hook-lifting board F, having depending from it the upper guide
board F, see Fig. 10, for the tail cords G so that the said hook-lifting board and
upper guide board move together in unison.
These two boards have, however, a motion at times in unison with the rising and
falling rods E2 and at times a motion independent thereof.
The hook lifting board has suitable end pieces which are bolted by bolts 155 to
carriages F³ fitted to slide vertically in the slots 118, in the Jacquard frame A*
below the carriages E¹.
These carriages FS at opposite sides of the loom have at their outer sides suitable
studs as which receive short links F which are jointed to levers F* pivoted
at F, the opposite ends of the said levers, broken off in Fig. 3, to save space upon
the drawing, having attached to them rods F, the lower ends of which are jointed
at F to a hand lever F10 pivoted at its lower end to a lever 43 in turn pivoted
at 44 and having a suitable roller or other stud, as F10, which is acted upon during
the rotation of the main shaft by the periphery of a cam F", see Fig. 32, bolted or
otherwise secured to the inner side of the large gear wheel C², fast on the main
cam shaft.
By turning the lever F10 outwardly from its position Fig. 1, the rod FB will be
drawn down and turn the lever in the direction to raise the lower hook
board F.
The catch 408 attached to the lever F is made as a spring to engage frictionally
one side of the rod F to thus hold the lever F10 in the position shown in the
drawings.
To those conversant with Jacquard mechanism, it will be understood that all the
hooks & must be lifted so that their upper hooked ends 135 will be entirely free
from the griffs 100 of the top board prior to bringing the Jacquard cards forward
to act upon the Jacquard needles to select these hooks which are not to be kept up
and at such time all the hooks must be free to be moved easily.
The hook lifting board F accomplishes this, and when the moving parts, of which
the top board E is the crown, has been elevated into its uppermost position, then
the cam referred to acts to raise the hook lifting board which temporarily
lifts the upper hooked ends of the said hooks above the griffs, and the Jacquard
needles having been operated to make the next selection to constitute the next row
of tufts to be made, the said hook board is permitted to drop until its ends meet the
adjustable rests 154 on the rods E3, after which the top board and its attached
parts descend, but the said descent does not take place until the proper shed is
open for the reception of the tufts.
The hand lever referred to is to enable the operator to raise and lower the hook
lifting board by hand which is a matter of very considerable convenience when it.
is desired to overcome any disarrangement of the needles.
The Jacquard cylinder is of usual construction, as are the devices for
actuating it, so it is only necessary to state that the said cylinder derives its
horizontal motion from like links J at each end which connect with arms J' of a
rock shaft J2 having a third arm J which by a connecting rod J is jointed to a
radius bar Jo, pivoted loosely upon a stud J' of a stand secured to the loom side.

page_text: This same stud has also mounted loosely upon it a radius bar J to which is
jointed a connecting rod J attached at its lower end to the end of a lever 64
having its fulcrum at Jo, the said lever having a roller or other stud which enters
a cam groove J in the cam F1 secured to the inner side of the large toothed
wheel C referred to.
Ordinarily the two connecting rods referred to are in one piece, but in this
invention the two radius bars have been interposed.
These radius bars each have a hole through them from side to side, see Figs. 9°
and 9, the said holes being in line, and the radius bar Je first referred to has an
ear which receives a vertical pin J upon which is mounted a hand lever J"
having a lug J which may be made to enter both holes in the said radius bars
and lock them together so that they will move in unison, but when for any reason
it is desired to rotate the pattern cylinder or actuate it backward or forward, the
said hand lever may be moved to withdraw the said projection from the hole in the
radius bar J, and there-after the operator by an engagement of the said hand
lever may actuate the Jacquard pattern surface, this being of very considerable
importance as it enables the cylinder to be adjusted to correct any faults in picks
or weaving.
The lowering of the hook supporting board F to move the upper ends of the
hooks G connected to the needles next to be used, away from the griffs 100 of the
top-board, takes place immediately after the action of the Jacquard boards upon
the needles, and the lowering of the hook board permits the hooks which are
supported only by it to have their connected tuft yarn carriers or needles descend
at their lower ends below the pocketed carriages H³, and at this time the evener
levers 25 are moved into their farthest position toward the rear of the loom, and
the carriage evener H acts upon the front ends of all the carriages and moves
them to the rear ends of the tracks.
The needles having been dropped below the carriages, the evener lever 25* now
starts forward, and the evener 146* acts against the dropped tuft yarn carriers or
needles, carrying them all forward against the evener 146 but as stated, when two
tuft yarn carriers or needles have been dropped by accident, in any one carriage,
then the action of one of the said needles c against the evener 146 carried by the
lever 25 will throw the extension 153 of the evener into position to operate the leg
referred to and effect the stopping of the loom.
When the eveners are closed together and the dropped needles care in one
straight line across the warps, the said eveners stand underneath all the elevated
tuft yarn carriers or needles so that in case any should drop from any accident they
will be caught upon the said eveners.
Each portion A¹ of the loom frame has a suitable stand K upon which is
pivoted at K an arm K made adjustable on the said stand by means of an
adjusting screw K³ to rest upon an ear K', a bolt K extended through the said
arm and through a slot in the stand serving to confine the arm in adjusted position.
These arms, one at each side of the loom, see Figs. 24 and 22, at their free ends
receive stud bolts K upon which are mounted to turn, the arms K, K³, to the
lower ends of which are attached respectively the shear blades K, K¹.
The arms K have jointed to them links K" attached to arms K¹³ of a tubular
shaft K" having an arm K provided with a roller or other stud which enters a
cam groove at one side of a cam K, shown separately in Fig. 27, and fast on the
cam shaft B
The arms K' have jointed to them connecting rods K" attached to arms K18
secured to the shaft K18.
The shaft K has an arm K connected by link K" to a lever K" pivoted at K"
and having a roller or other stud acted upon by the cam K", shown separately
in Fig. 28.
The arm K' carrying the front one of the two blades is composed of two parts,
one of which slides longitudinally on the other, the said two parts being adjustably
connected by the ends of a right and left hand threaded screw, 160, the rotation of
C

page_text: which enables the arms to be lengthened or shortened as desired, the arms being
confined in adjusted position by suitable bolts 161 extended through both of them,
one of the arms being slotted where the said bolt extends through it.
The under side of the fabric at the time the tuft yarn is being cut, is supported
by the fabric lifting bar or device, see Figs. 34, 22 and 24, which as described
may be actuated so as to lift the back of the fabric always into exactly the same
level or horizontal plane when the tuft yarns are to be cut off.
The vertical adjustment of the cutter blade K by lengthening or shortening the
arms K', as described, enables the edge of that blade to be always kept in exactly
the proper position with relation to the cutting edge of the shear blade Klo
notwithstanding wear due to grinding or otherwise.
In this invention it is possible to exactly insure the like lengths of each row of
tufts, and it is possible to make the tufts of any desired length according to the
stock being used, for the cloth lifting bar may be adjusted as desired.
The cloth lifting bar has ears at its lower side near each end, which ears are
jointed to arms of a rock-shaft by a rod ³.
The rock-shaft has an arm a joined by an adjustable connecting rod to one
end of an elbow lever 8 pivoted at 7 upon a suitable stand mounted on a girt or
otherwise.
This elbow lever has a roller or other stud, see Fig. 22, which is acted upon
by a cam, shown separately in Fig. 19, and dotted in Fig. 22.
The bearing for the shaft has a fixed ear, against which strikes a toela
forming part of the cloth lifting bar, the said toe and car preventing the cloth
lifting bar from being tipped too far toward the reed r.
In the Patent No. 7313, the front cutter blade remained stationary nearly
above the row of tufts being. inserted, so that it was difficult to see or get at the
fabric at that point, but herein the front cutter blade is made movable so that it is
swung out a considerable distance beyond the cloth making point while the tufts
are being inserted and secured in place and is held there until the needles c are all
lifted preparatory to cutting off the tufts, at which time the front cutter blade is
moved forward nearly against the tuft yarns, and comes to rest, and thereafter the
back cutter blade is moved forward to cut off the yarns, and then both bars are
opened or separated, as before.
The hooks G made of wire are shaped as best shown in Fig. 18, that is the lower
ends of the wires are turned back upon themselves parallel for a short distance to
form an eye s¹ into which the tail cords G are tied, and then the wire is so bent as
to form two parallel portions at some little distance apart leaving a shoulder 163,
which when the needles rest upon the hook lifting board Fenter pits 164 in the
longitudinal bars 165 of the said needle lifting board, as at the right in Fig. 18,
where it will be noticed that the tail cord supporting eye of these hooks is at one
side of the shoulder referred to so that the weight of the needles c tied to the tail
cords, normally acts to press the hooked upper ends 135 of the needles away from
the griffs 100 and against one of the longitudinal bars 110 of the controlling
frame E³ as at the right in Fig. 18.
C
This action greatly assists the usual springs on the Jacquard needles and enables
the said springs to be made lighter or smaller, and if desired the said springs
might be altogether omitted, but they have been herein retained for additional
safety.
This provision of a shoulder near one edge of the needle and an eye near its
other edge and close together as represented, and placing the parts of the needle
parallel to the main body of the wires above the shoulders, enables the length of
the needles to be shortened below the shoulder, and it is obvious that the tendency
of the weight of the tail cord and the needle attached to it will be to turn the
said needle about the said shoulder and away from the griff bars 100, when the
hooks 135 turn as in Fig. 18, or by turning them in the direction shown in Fig. 13ª
the weight of the tail cords will normally place the hooks 135 in position to be
engaged by the said griff's.

page_text: The needles herein shown have their broadened parts s, which enter the needle
guide board E, above their shoulders 163, which is also a feature of invention,
and it will be obvious that the closer the shoulder is to the eye in which the tail
cord is tied, the greater the swinging motion which the weight of the tail cord and
needle c will give to the hook.
In weaving tufted carpets in a loom of the class described wherein the weft or
filling is inserted double and caught at the opposite side of the shed by a thread
carried by a small shuttle, it has been found that when the shed is closed, after the
weft has been drawn back, that the tension of said weft on the selvage warp of
the lower shed, near that selvage prevents it from rising sufficiently to properly
close the shed at that selvage and so keeps the tufts at that point down below the
adjacent tufts.
I ascertained by experiment that this difficulty could be overcome by putting
greater strain on the said selvage warp and to do this I have added to the loom
what I denominate a selvage thread lifter, which I will now describe.
The usual harness frames, not shown, because common in the Patents referred to,
run at their ends in guides w³, supported upon suitable stands 20³, see Figs. 22
and 23.
Upon one of these guides I have arranged loops w' in which slides a heddle
carrier having a heddle w which receives one of the selvage warps.
This heddle carrier is connected at its lower end by a link to a lever w³
having a roller or other stud at its end which is acted upon by a cam 10° fast on the
cam shaft B, the said cam being shown separately in Fig. 31.
In Fig. 33, I have shown separately the lay operating cam X, it being shaped as
represented to impart to the usual lay d² its forward and backward movement, the
said cam acting against the arm 1³, connected to a rock-shaft H2, having an
upright arm 409, which is jointed by the connecting rod to the lay, there being
like arms and rods at each side of the lever all substantially as in one of the
Patents referred to.
I have shown one form of stop motion mechanism under control of the
extension 153 to release the shaft a and stop the loom whenever two carriers or
needles c drop between the separated eveners; also one form of stop motion
mechanism between the shuttle thread controller and the said shaft to stop the
loom when the selvage shuttle thread breaks, but I do not desire or intend to limit
this invention to the exact form of the devices and number of pieces shown and
described, as it will be obvious that the shape and construction of these parts
might be variously modified without departing from my invention, I being the first
to provide a loom of this class with stop motion devices for the purposes stated, so
far as I am aware.
In the Patent No. 7313, the point of the needle was made hollow, but the tuft
yarn was for quite a distance led along the outside of the needle in the direction of
its length.
In practice it has been found that the tuft yarns become entangled with each
other on their way to the delivery eyes of the needles, and to obviate this I have
made the needles hollow or tubular from at or near their yarn receiving eyes 400,
see Fig. 6, to their lower ends.
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 in tuft carrying looms is :-
1. A series of tuft yarn carrying needles having their yarn receiving eyes
arranged at different distances from the lower ends of the needles and made tubular
from the said eyes to their lower ends to thereby prevent the rubbing together of
the tuft yarns while the said tuft yarn needles are being moved or selected, substan-
tially as described.
2. A tuft yarn needle having a tubular portion to receive the tuft yarn and
provided at its interior with points to enter the tuft yarn, the points being directed

page_text: toward the delivery end of the needle to prevent the drawing back of the tuft
yarn into the needle, substantially as described.
3. A tuft yarn needle having nibs at its upper end, combined with a nib-board
having a series of bars or rods to receive against them the said nibs and support the
said needles which are to be used in the production of a row of tufts then to be

substantially as described.
5. A series of tuft yarn needles, a series of pocketed carriages, tracks arranged
side by side parallel to the warps and on which the carriages slide, and evener
carrying arms having eveners made broad enough to extend under the needles
which are not selected and dropped into position to be acted upon by the inner
edges of the eveners, so that should a second needle drop by accident in any one
carriage, it, will strike upon and be stopped by the upper side of the evener, substan-
tially as lescribed.
6. The combination with a series of tuft yarn needles, a series of longitudinally
sliding pocketed carriages, tracks on which the carriages slide, and a positively
actuated evener to act on the lower ends of the selected needles below the said
