Apparatus employed therein.

1 ALFRED GEORGE BROOKES of 55 and 56 Chancery Lane in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
to be as follows:-
:
Hitherto the width of fabrics which could be practically produced on power
looms for weaving tufted fabric has been limited because of the difficulty caused by
the liability of the warping or twisting of the tuft beams or frames, the longer the
said beams or frames, the greater the liability to twist or warp and the greater
the difficulty to ensure correct alignment of the ends of the tuft yarn tubes carried
by the beam or frame, any lack of alignment resulting in misplacing or loosing a
tuft, thereby damaging the fabric and disfiguring the pattern.
It is desirable to weave wide fabrics for rugs and the like, and therefore to use
long tuft beams or frames, and to obviate the warping and twisting referred to, the
invention comprehends suitable construction and devices by which to effect up and
down or lateral bending or adjustment of the beam or frame to enable any warping
or twisting to be corrected for the maintenance of the tuft yarn tubes always in
proper alignment or position.
The invention also comprehends the use in connection with the transferring arms
which engage the ends of a tuft beam or frame and move it from the carrying
chain to the warp, of a connecting bar to sustain and stiffen the tuft beam or frame
while its tubes are inserting the tuft yarns into the warp.
Hitherto during the insertion of the tuft yarns in the warp and the formation
of the loops and tightening of the same about the weft threads, it has been the
usual practice to clamp the spools or tuft yarn carriers to prevent the tuft yarn
pulling off.
This is objectionable for many reasons, and the invention therefore comprehends
the use of a clamp acting directly upon and to clamp the tuft yarns themselves, and
not the carriers therefor, said clamp preferably acting in opposition to or against
the stiffening bar referred to.
To improve the mechanism for moving the needle which carries the weft thread,
there are provided two cams, one of which moves the needle carrier in one
direction, and the other moving the said carrier in an opposite direction, the two
being so shaped that the needle carrier or some connected part is always in contact
with both cams, providing an absolutely positive reciprocating motion without any
back-lash or lost motion.
In looms for weaving tufted fabrics, the tuft yarn tubes or quills are usually
made from tin or thin metal, the upper ends of the tubes being left unprotected.
My correspondent has found that the passage of the tuft yarns through these
tubes tends to roughen the yarns, forming a fuzz which is apt to clog the yarns in
their tubes and prevent proper operation of the loom.
To correct this, there is provided a guard arranged above the tuft tubes and
yarn
projecting over and to cover the top edges thereof at that side or sides where the

page_text: yarn is likely to rub, to thereby obviate the roughing-up of the yarns upon the
edges of the tubes, the yarns being kept by the guard out of contact with the said
edges.
It is also preferred to strike up the tuft yarn tubes or quills from sheet metal
blanks overlapping and soldered or otherwise secured at their outer sides, the said
tubes or quills being preferably made wedge-shaped to better enter between the
warp threads.
In the production of tufted carpets, especially rugs, etcetera, it is frequently
desired to provide borders all around a centre, and to do this, certain beams of the
chain have their tuft yarns arranged to provide loops for the centre and side
border, while other beams have their tuft yarns arranged for the production of the
end borders, and this weaving is facilitated by mounting the tuft yarn beams in
their carrying chains in such manner that, say, the first, third, fifth etcetera, beams
in the chain may be used to produce one part of the pattern, and the second, fourth,
sixth, etcetera, beams another part of the pattern, and these beams are brought
alternately into proper position with relation to the warp threads at the fell or
weaving point so as to be taken therefrom to have the tuft yarns wound upon them,
properly inserted to form a row of tufts having the desired colors.
My correspondent has devised novel means for imparting the desired movement
to the chains, which consist essentially in two pawls adapted to engage pins or
teeth on a disc, only one pawl being in operation at a time, the disc being connected
with a toothed wheel which moves the chain by means of a pin and a series of holes
through which the pin is inserted.
The holes are so spaced that, the chain having made one complete movement,
presenting alternate tuft yarn frames in operative position, by withdrawing the pin
and turning the toothed wheel relatively to the disc or vice versa, so that the pin
may be inserted in the next hole, the timing mechanism will be so changed that
upon the next complete movement of the chain the alternate tuft yarn frames which
were not presented during the first movement will during this second movement be
presented, those presented in the first movement being in the second movement
carried up
in inoperative positions.

Improvements in the Weaving of Tufted Fabrios, and in Means or
Apparatus employed therein.
A communication from abroad by HORACE WYMAN, of Worcester, in the County
of Worcester and State of Massachusetts, one of the United States of America,
Loom Builder.
I ALFRED GEORGE BROOKES of 55 and 56 Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Hitherto in power looms for weaving tufted fabrics the liability of the tuft beams
or frames to warp or twist and thereby throw out of alignment the tuft yarn tubes
carried by the same has made it necessary to use frames or beams of comparatively
short length, wherein the warping or twisting is not manifest to any considerable
degree, and the use of these short beams or frames has necessarily restricted the
width of fabrics capable of practical production on such looms; it being evident

page_text: that any lack of alignment in the tuft yarn tubes, resulting from the twisting or
warping of a long frame or beam, will cause misplacement or loosening of the tufts
to the damage or disfigurement of the fabric and its pattern.
It is desirable, however, to weave wide tufted fabrics for rugs and the like,
and, therefore, the use of long tuft yarn beams or frames are quite necessary,
and to obviate the warping or twisting of these long beams or frames, referred
to, my invention comprehends a suitable construction or device by which to effect
up and down or lateral bending or adjustment of the beams or frames to enable any
warping or twisting to be corrected for the maintenance of the tuft yarn tubes
always in proper alignment or position.
The invention further comprehends the use in connection with transferring
arms, which engage the ends of a tuft yarn beam or frame and move it from the
carrying chain to the warp, of a suitable support for and to sustain the tuft beam
or frame, while its tubes are inserting the tuft yarns into or between the warp,
thereby preventing vibration or bending of the beam or frame at times when
absolutely correct alignment is necessary.
Hitherto during insertion of the tuft yarns in the warp, and during the formation
and tightening of the loops about the weft threads, it has been customary to
clamp the spools or tuft yarn holders to prevent the tuft yarns pulling off.
It is desirable, however, that the clamp act directly upon the tuft yarns and not
upon the holders therefor, and my invention comprehends such a clamp, which,
preferably in acting upon the tuft yarns, acts in opposition to or against a stiffener
bar or support, which may be the support above referred to.
To improve the mechanism for moving the needle, or other weft carrier, there
are provided two cams which continuously act upon and independently move the
said carrier in opposite directions, these cams being preferably relatively
adjustable.
My invention also comprehends formation of the tuft yarn tubes or quills by
striking up the same from sheet metal blanks overlapping and soldering or
otherwise securing the edges at the outer sides of the tubes, said tubes being
preferably made wedge-shaped at their lower ends that they may better enter
between the warp threads.
Another feature of my invention is the construction of a feeding mechanism
for feeding the tuft yarn beams or spools into position for insertion of their tuft
yarns in the fabric, and whereby the chain of spools or beams may be moved in one
or the other direction as necessary.
The above together with other features of my invention will be hereinafter
described and pointed out in the claims at the end of the Specification.

My invention herein to be described relates particularly to looms of the class
shewn in the Specifications of Letters Patent Nos. 980 and 981 of January 17th
1893 granted to the present applicant, to which reference may be had, the letters
of reference used in the said prior Patents being so far as possible used in this
present application for Patent.
Referring to the drawings, the frame A, having suitable bearings for the cam
shaft B, the transferring frame comprising the side bars 18, jointed, at their lower
ends, to the slide bars e, and at their upper ends at e* to the outer ends of the
arms p10; fast on the shaft p* journalled in suitable brackets on the frame; the
pocket arms p, adjustably attached to the arms 18 of said transferring frame, and
provided at their lower ends with usual pockets 2010; the rod p** joining and
separating the pockets 10, the clamps 7, actuated through the rods p*, connected
to the bell crank levers p on the pivot shaft p* journalled in the arms pl*, and
in turn connected by links e" with the arms e fast on the shaft * also journalled
in said arms pl*, and provided with an arm e* connected by a rod e** with the
cam lever el, fitted with a roller el actuated by the cam els on the cam
shaft B3; and the tuft yarn pusher a*, are shewn as similar or equivalent to the
correspondingly lettered parts in the said Specifications of Patents Nos. 980
and 981 referred to, they operating in precisely the manner therein described, and
well understood by those conversant with the art.
Referring now to Figs. 1, 2, 3 and 12, there is herein slipped upon the shaft e¹*,
between the arms p10, a long sleeve t, provided with two like downwardly pro-
jecting clamping arms t', t, carrying at their lower ends, the clamping plate or
strip t, preferably of rubber or other soft or yielding material held by a suitable
supporting pieces, see Figs. 2 and 12, said clamping strip, or clamp, as I shall
hereinafter designate it, extending entirely across the front of the loom, from one
to the other of the pockets wo, and adapted to press against and clamp or hold
the tuft yarns on a fine just above the tops of the tuft yarn tubes or quills to be
referred to.
Referring now to Figs. 1, 3 and 3, the sleeve t, at one of its ends, inside the
arms po, has cast upon or secured to it a hood, which encloses the joint at the
end of the arm 710*, and outside the said arm the said hood is provided with a
downwardly extended arm to to which is adjustably connected at t, the rearwardly
extended arm t, connected at its outer end by a rod t with a cam lever t³,
fulcrumed at 10, and provided with a roller t", adapted to be acted upon by a
suitably shaped cam t¹ on the cam shaft B³, see Fig. 2.
The cam, is so timed that it, acting through the cam lever t' and connections,
holds the clamp arms t¹ and clamp 3, out or to the right Figs. 2 and 12, as
indicated in dotted lines, until the transferring mechanism has taken a tuft yarn
beam and its carriage and tubes, from the carrying chains, and holds said carriage
in its pockets wo, when the said cam 1, releases said clamp and permits the
spring, see Fig. 1, to draw it inwardly, or to the left, to clamp the tuft yarns
tightly against the bar carrying the tuft yarn frame or spools.
The ends of the tuft yarns having been looped into the shed of the warp, and
the weft or filling laid in the usual manner, the transferring mechanism again
raises the tuft yarn beam and its carriage, with the tuft yarns still held by the
clamp, in order to tighten the loops of tuft yarn about the weft or filling,
and to draw the ends of the yarn down to their proper position,

page_text: As soon as the tuft yarn loops have been properly drawn or tightened, the
cam t¹ releases the clamp and permits the tuft yarns to unwind from the beam,
the ends being still held in the warp to provide ends of sufficient length for a
new series of tufts when the said beam shall be again presented to the warp,
after which the tuft yarns are severed by usual shearing or cutting mechanism
and the transferring mechanism replaces the beam in the chains to be fed forward
to present the next beam or series of yarns to the warp.
The novel clamp herein described, acts directly upon and holds the tuft yarns,
thereby preventing any pull upon and to rotate the beam or spool upon which
the tuft yarns are wound, said clamp being thus distinguished from the type of
clamp illustrated at ps* which acts upon the beam or spool, and not directly upon
the tuft yarns.
The distinction is important for the improved clamp is necessarily more positive
and certain, and by acting lower down, close to the tuft yarn tubes or quills,
the length of the tuft yarns between the clamping line and the loops is very much
lessened, and the excess of movement of the parts necessary to compensate for
the stretching of the tuft yarns in tightening the loops, is correspondingly.
removed.
So far as known to my correspondent he is the first to directly clamp the tuft
yarns, as distinguished from clamping the beam or holder upon which the tuft
yarns are wound, and the invention is not therefore limited to the particular
embodiment herein shown, for it obviously may be varied without departing from
the spirit and scope of the invention.
Referring now to Figs. 1, 3 and 5 to 10 inclusive, the tube frame consists of a
bottom bar and a top bar cl, said bars being united at their ends by suitable
stauds, which, in this instance of my invention, afford bearings for the outer end
journals of two tuft yarn beams. As herein shown the bottom bar 80 is grooved
along its front edge to receive the tuft yarn quills or tubes c, shown as folded or
bent into shape from blanks e, the edges of the blank being lapped over each
other and soldered at the fronts of the tubes as shown, the lower ends of the tubes
being cut off at an angle to form sort of points to better enable the tubes to enter
between the warp threads during the operation of the loom.
So far as known to my correspondent he is the first to form tuft yarn tubes of
this shape and in this manner.
The downwardly and backwardly tapering points of the tubes are pinched as
at to sharpen the same.
Each bar of the tube frame is shewn as provided with a bending point, for
simplicity made as a cross cut, indicated in the top bar at 2, and at opposite sides
said bending point 2 my correspondent has attached to the bar by suitable manner,
as by screws 3, suitable blocks c³, forming part of an adjusting device, said blocks,
as herein shown, having one or more ears 4 in which have been placed adjusting
screws, said screws having adjusting nuts, shewn as three in number and
marked 5, 6 and 7, and by changing the position of the nuts on said bolts in one or
the other direction said ears may be forced apart or pulled together, that depending
upon whether it is desired to bend the bar down or up.
At a point between the ends of the bottom and top bars there is provided a
beam stand e, see Fig. 10, made preferably as a casting having its ends flanged to
partially embrace said bars, and I have shown said stand as slitted or bifurcated at
one end, its lower end, as at 8, and straddling the bending point or cross cut in the
bottom bar, there having been combined with suitable ears 9 of said stand, an
adjusting device shown as a screw 10 having suitable nuts 12, 13, 14, preferably
three in number, and by adjusting said nuts on said screw the bottom bar may be
strained or sprung laterally, or be adjusted in such manner as to deflect it more
or less laterally and thus neutralise any lack of alignment in a direction at right
angles to the length of the loom.
I have shown means whereby the bottom bar may be bent or swung up or down
or laterally between the ends as by a hinge, and it will be obvious that the adjusting

page_text: devices may be applied as shown to both or to one bar, and that instead of the
cut 21 may use any equivalent to thereby afford for the ends of the bar a
turning point about which to be moved, to enable the bar to move one end with
relation to the other end.
The intermediate stand has combined with it a suitable cap car, shown as
hinged at, see Fig. 8, said cap forming one side of a box or bearing to receive
the journals 15 at the contiguous ends of a pair of tuft yarn beams d*, said cap
having a suitable locking device to hold it in position.
I have herein shewn the journals 15 as slabbed off, or partially cut away, see
Fig. 11, to thus leave flattened faces to enable one journal to overlap the other
when brought together in the same bearing stand, the journals when shaped to
overlap and engage each other serving the purpose of couplings between two
adjacent tuft yarn beams or spools to thus ensure rotation of the same in unison.
I have shewn the bottom bar as provided with suitable friction springs or
devices adapted to bear against the head of each beam and prevent the same
turning too freely.
The outer ends of the bottom bar have the usual fingers and springs h¹ to
cooperate with usual chains for carrying the tube frames when not being used for
the insertion of their yarns for tufts.
I have herein shewn the frame as provided with two beams, and while I have
shewn but one cut 2, and adjusting devices at each side of it, this invention is not
limited to any particular number of cuts, nor to any particular adjusting device or
devices for bending the bar.
It will be noticed from the foregoing description that the tube frame, or the
frame to which are attached the tubes, through which are led the tuft yarus, in
order that they may be inserted into the sheds made in the body warps, as
provided for in looms for weaving tufted fabrics, has a plurality of spools, and
thereby it is possible to weave tufted fabrics of any desired width, and by
providing the tuft frames with adjusting devices for springing or bending the
same, so that the botton bar may be bent up or down relatively to the warp, or
laterally if needed, it is possible to effect a proper alignment of the tubes connected
with the bottom bar with relation to the warp, with which, by suitable weft, will be
incorporated the tuft yarns wound ou the said spools or beams, when the tuft
frames are brought into position by the chains and are lowered to deliver up their
yarns and afterwards brought back again in usual manner, as fully described in my
said Specifications of Patents No. 980 and No. 981 referred to.
The up and down and side adjusting devices might be applied to the lower bar of a
tube frame and be productive of advantages, and my invention for aligning the
bottom bar is not to be limited in all instances to the exact tube frame shewn for
it is useful in connection with any tube frame.
To provide a firm back support for the tuft yarn frame and its bar c80, carrying
the tuft yarn tubes or quills, and to prevent bending of the said bar when the
clamp is pressed against it, I have herein shewn and it is preferred to employ a
suitable back supporting bar u, carried at its ends in and by the bracket
arms p, p².
This back support u is preferably angular, as shewn in Figs. 8 and 12, to
constitute both a bottom and a back or side support, thereby effectually preventing
sagging or bending from alignment of the bar carrying the tuft yarn tubes. and
absolutely ensuring proper alignment and insertion of the tubes, each frame with
ite tube carrying bar being first seated in this support u before its tuft yarns are
inserted in the warps.
The frame-work has a stand m having bearings for the shaft m', provided at its
end with a toothed gear m², alongside of which is a sprocket gear m³ over which is
extended the usual chain m' having single and double links with which co-operate
the fingers and springs h¹ attached to the tube frames described, and furnishing
means by which the said frames are connected with and moved by said chains and
withdrawn therefrom for insertion of their yarns in the warp.
°

page_text: I have not herein shewn in detail the devices for taking the tube frame from the
chain, moving the tuft frame to insert the tuft yarns in the usual body warps, and
afterwards cutting off the said yarns and restoring the frame to the chain, as said
devices are and may be common, as for instance such as are represented in my
Specifications of said Patents No. 980 and No. 981.
As herein represented, the outer face of the toothed gear, referred to, is
provided with a series of holes n³, said holes being adapted to receive in them a
locking device n, see Fig. 12ª, represented as a sliding pin having an enlarged
head, carried by and sliding in a toothed plate nº, said locking device being adapted
to lock the toothed plate to the toothed gear.
The toothed plate n' has a series of teeth n' extended therefrom, with which
co-operate the pawls no, no, one pawl at a time, the pawl n³ operating the toothed
plate and gear in a forward direction, as represented by the arrow near it, and
the pawl when employed operating said parts in a reverse direction to
thereby change the direction of the chain moved by the sprocket wheel as may
be necessary.
By detaching the locking device n' the loom may be operated without moving
the chain, for the purpose of weaving without inserting the tuft yarns for a space
between two rugs or finished fabric.
The pawls n³, n, are pivotally mounted upon pawl carriers o, o', and each has
its fulcrum on a stud o³, each pawl having connected with it a suitable spring
as o by which to keep the pawl pressed toward the plate nº, as represented by
the pawin or to hold the pawl away from the said plate, as represented by the
pawn.
The operator may easily throw either pawl out of engagement or into engagement
as desired.
The pawls n³ nº are actuated by the rods A³ A* attached to suitable connecting
parts operated by a cam on the shaft B' or equivalent mechanism these intermediate
parts (not shown on the drawings) may be substantially such as are represented in
the Specifications of Nos. 980 and 981 hereinbefore referred to.
Referring now to Figs. 13 to 17 inclusive, I will now describe the mechanism for
operating the weft inserting device, herein shown as a needle.
The main or power shaft B³, as shown, has a pinion C', in mesh with and driving
a larger toothed wheel C, fast on the cam shaft B³, said wheel C also meshing with
and driving a pinion C*, fast on an actuating shaft i, journalled in suitable bearings
on the frame at one end of the loom.
Upon this actuating shaft i, is made fast a sleeve ¹, having flanged ends, to
which are bolted respectively the needle-actuating cams,, the fastening bolts,
as shewn, passing through slots in said cams to admit of proper relative
adjustment of the two cams.
The cams, shaped as best shewn in Figs. 13 and 14, act respectively upon
the rollers, jourualled in the upturned ends of two roller carriers, shewn as
levers,, fulcrumed respectively at 10, 11 on an arm of the frame.
The upturned ends of the carriers or levers referred to, are found to constitute
heads, they, in the present instance, having in their bottoms, hemispherical sockets
to receive respectively the spherical or ball-like ends of the two rocker
arms, the latter made fast by a set screw 50 in its hub, upon a short needle
haft 60, journalled in suitable bearings in the frame, and the former arm projecting
rom a sleeve, loosely fitting said shaft, see Fig. 16.
The sleeve is held between the hub of the arm 2 at one end, and the hub
of an arm is, fast upon the shaft 610, at its opposite end.
An arm on that end of the sleeve opposite the rocker arm ", is connected
ya tension spring ", with the arm 1, referred to, said spring, therefore, con-
tituting a connection between the sleeve and shaft, and acting to draw the two
owards each other or rotate them in opposite directions to cause their rocker arms
o raise the rollers,, into contact with their respective cams.
A set screw, threaded in an ear of the rocker arm, acts against the

page_text: flattened or broadened base of the rocker arm, and serves as a stop to limit
the spring-actuated movement of the rocker arms towards each other and towards
their cams.
By means of the set screw and the spring described, all lost motion between the
rocker arms and their rollers and the cams, may be taken up or regulated and a 5
positive movement of the former from the latter,. obtained.
When the rocker arm is depressed by the roller, it acts through the spring {"
and arm to also rock the shaft 610 in the same direction, and when the rocker
arm is depressed by its roller 7, it operates directly upon and to rotate the
shaft 10 in the same direction.
C,
Upon the outer end of the shaft 610 is fixed the weft or needle lever connected
by a link with the needle carriage B', rocking of the said shaft 61° causing
positive vibration of the needle lever and reciprocation of the needle.
The sliding carriage B' adapted to slide on the guide or rail B³, carries the weft
needle B', which is attached to said carriage by a screw B, and is adapted to
introduce and leave a loop of weft in the warps as the carriage is reciprocated.
The guide & for the free or pointed end of the needle is mounted upon the rail B³
and the opening therein through which the needle B' works must necessarily be
such as to admit passage therethrough of the full cross section of the needle, but it
will be noticed that just back of the point of the needle a portion of the body of
the latter is removed, as at t*, to clear the usual shuttle arranged and operating
at the opposite side of the loom.
If there was nothing to prevent, the needle, when in its position shewn in Fig. 14,
during the operation of the loom, might vibrate vertically within the hole in the
guide t, inasmuch as its cross section does not, in such position, completely fill the 1
hole or opening in the said guide.
To obviate this liability of vibration my correspondent has enlarged the guide
opening to a size sufficient to receive the presser t¹ shewn as a lever pivoted at t³,
and acted upon by a spring to, which presses the acting end of the lever against the
underside of the needle and keeps the latter, whatever its cross-sectional area, at
the point acted upon by the lever, always pressed upwardly against the top of the
opening in the guide t, that is, against the guiding surface, in contact with which
the top of the needle moves.
Thus in Fig. 14, the presser ¹ holds the needle firmly against the top guiding
surface, and as the needle moves forward or to the left in laying the weft thread,
the presser yields and moves downwardly before and to permit the increase or full
cross section of the needle to pass through the guide, yet holding the needle always
against the top guiding surface.
This arrangement ensures accurate entrance of the needle between the warp, for
whatever play or looseness may exist between the needle and its guide the former
is always pressed against the top guiding surface, which, when properly adjusted,
reuders it impossible for the needle to enter in any but the correct line, the presser
further acting to prevent undue vibration of the needle at any time during its
movements.
The rocker arm ¹³ is always in operative contact with the cam *, therefore there can
be no appreciable rebound or recoil of the needle lever c, at the end of its outward
movement to the right Fig. 14.
By varying the shapes of the cams i, *, the movements of the weft-lever and
its needle may be varied, but the said cams are always so shaped as to impart a
positive rocking movement to the shaft 10, without lost motion of any sort.
By journalling the rollers, in suitable carriers,, independent of the
rocker arms, and shewn as fulcrumed about axes parallel with the axis of the
actuating shaft, and connecting the said carriers by ball and socket or other form
of universal connection with the rocker arms for the weft lever, I am enabled to
make both the cams and their cooperating rollers with straight faces i.e., with the
elements of their faces straight and parallel with the axis of rotation, whereas if
the journals were journalled in the rocker arms, either the cam surfaces or the
1

page_text: roller surfaces would have to be curved to accommodate the rocking movement
of the said arms about the axis of the shaft 10, standing at right angles to the
axis of rotation of the cams..
This part of my invention is not limited to the particular construction herein
shown and described, for it is evident that the same may be varied without
departing from the spirit and scope of the invention.
Ilaving now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a loom for wearing tufted fabrics, having a movable yarn holder upon
which the tuft yarns are wound, and a series of tuft yarn tubes connected therewith,
the use of a tuft yarn clamp acting directly upon the said tuft yarns.
2. In a loom, having a tuit yarn carriage containing a series of tuft yarn tubes,
and a tuft yarn holder journalled in said carriage, the use of a clamp to clamp
the tuft yarns between said holder and tubes.
3. The transferring frame, the tuft yarn beam, the tubes, and holding bar
therefor connected to and movable with said beam, a clamp for and to hold said
beam against rotation, and an additional clamp acting directly upon and to hold
the tuft yarns.
4. In a loom for weaving tufted fabrics, the shaft m¹ having sprocket wheels, the
tube frame carrying chains mt, a series of tube frames having tuft yarn spools,
the gears m³, the toothed gearn, the toothed plate and a locking device to connect
the same and the gear n at different points, a pawl and ratchet mechanism, and
actuating devices therefor whereby said chain may be moved in either direction
at will.
5. In a loom containing a tube frame and its connected series of tuft yarn tubes,
the use of devices to effect up and down bending of the bar carrying the tubes.
