- and the ends of the pile threads are extended up' between the wefts c, c (see Fig. 11, for instance), and in order to produce a weave of this kind the following arrangement isvmade: The ground warp threads a, a unwind from the usual warp-beams (not shown), mounted on the loom-,frame A, and the said ground warp threads pass from the warp-beams, through heddles B, B respectively to the fabric d passing over a breast-beam C arranged on the main frame A in the usual manner. For each two picks C, C, a different set of pile 'threads b is used, each set of pile threads b being carried on a tuft yarn frame D and the several tuft yarn frames D being removably mounted on anl tuft yarn frame D which is carried by the carrier E to an operative position is disconnected from the carrier,

transferred to the place of forming the knots, and after the knots are formed is returned to the endless carrier, and .the latter is caused4 to travel, to move the following tuft yarn frame into position to be removed, the said carrier traveling intermittently .in unison with the action of the loom. As shown in Fig. 1, a tuft yarn frame D reaches a removing position `when passing to the bottom (if a pulley E forming part of the means for supporting the carrierl E and preferably journaled on the main frame A of the loom proper.

Each of the tuft yarn frames D is preferably in thel form of a transversely-extending beam D on which is journaled a'tuft yarn spool F 'carrying thenseveral differently colored pile threads required for forming a row of knots across the width of the fabric, each of the threads passingthrough a hollow curved tuft yarn' tube G attached to the beam D On each end of the' beam D is arranged a catching device for connecting thetuft yarn frame .D with'the chains E2 of the endless cam'er Ev (see Figs. 18 and 19), each catching device consisting essentially of a fixed bar D? and a springhook D3 adapted to pass over the corresponding chain E2, as plainly indicated in the said Figs. 18 and 19. Each of the spring-hooks D3 extendsthrough an ope'ning inthe bar D, to form a cam-surface D* adapted t0 be engaged by the wall of aseat Hheld-on swingarms H forming part of the mechanism for carrying a tuft yarn frame D from the endless carrier E to an operative position for forming knots, as hereinafter more fully described. Normally the spring-hook D3 is in a. closed position over the corresponding chain E2, so that the frame'is properly supportedon anendless carrier and moves along with the same, b 'ut when the spring-arms H -move into an uppermost position (see dotted lines, Fig. 1) and the seats H engage the ends of the beam Dl and act on the cam-surface Df,

. for imparting a rocking motion to the said levers'Kl then the spring-hooks D3 are opened, to disengage the chains E2 of the `carrier and consequently allow the swing-arms H .to swing down with the tuft yarn frame D, to bring the latter to the operative position for forming the knots. The tuft 4yarn frame D, while seated on the seats H and while in an operative position above the ground Warp threads a, a', receives a rocking motion, so as to bring the tuft yarn tubes G and consequently the pile v'threads b between adjacent pairs of ground warp threads a, a', it being understood that when the tuft yarn frame D is moved into operative position, the free ends of the pile threads b of this tuft yarn frame are engaged and held in a clamping device I during the time the knots are formed.

1n order to impart a rocking motion to the tuft yarn frame D for the purposevdescribed, the following arrangement is made: On the trunnion H2 of each seat H is secured a segmental gear-wheel Hl (see Figs. 16 and 17), inmesh with a rack J pivotally connected with a lever J2 fulcrumed at J3 on the main frame A and connected by' a link J4 with a cam-lever J5 controlled by a cam (not shown), for imparting an intermittent rocking motion to the said lever J5, the rocking motion of the latter being transmitted by the link J4 to the lever J2, which thus imparts a sliding motion to the rack J', to turn the segmental gear-wheel H3 and hence the trunnion H2 and its seat H. As the beam D of the tuft yarn frame D is fitted in guideways in both trunnions H, it is evident that the rocking motion given to the trunnions causes rocking of the beam D1, to oscillate the tuft yarn frame D intermittently, to swing the. tuft -yarn tubes G in and out between sets of adjacent ground warp threads a and a.

In order Ato holdl the rack J' in mesh with the segmental gear-wheel H3 an arm H4 isI provided', fulcrumed loosely on the operative trunnion H2 and provided with a friction-roller H5 traveling on the top edge of the rack J.

Each 4of theV swing-arms H is fulcrumed at H on the mainframe A, and each of the said swing-arms is pivotally connected by a link K with a camlever-K, controlled by a suitable cam (notshown),

and 'consequently to the swing-arms H to swing the same up and down, for taking a used tuft yarn frame D back to the carrier E and for bringing the next following frame down into the operative position, for forming a new set of knots, as hereinafter more fully described. When the swing-arms H swing into an, uppermost position, to return a previously used tuft yarn frame D, then the seats H are caused to slide apart, to allow the spring-hooks D3 to close after the chains E2have passed between the spring-hook and the xed bar D2, so that the tuft yarnframe D under consideration is returned and refastened to the chains E2. of the` endless carrier. For the purpose described the swing-arms H are mounted to swing transverselya suf` cient distance to carry the seats H along in order, to

permit closing of the spring-hooks D3, and the said swing-arms Hare connected by links L (see Fig.l 16) with an armL fulcrumed on ashaft L2 arranged on the main frame, the arm L being also connected by a link L3 with a bell-crank lever L4 controlled by a cam (not shown), so that the arm L 'receives a rocking motion at the proper time, to swing the swing-arms H apartand to move the same toward each other whenever required. As the detail construction of this portion of the mechanism is similar to ones already in use, further description of the same is not deemed necessary.

The clamping device I previously referred to consists essentially of clamping jaws I and I2, of which the clamping jaw I2 is hung on links I3 connected with the'jaw I, and a spring I4 connects the jaws I2 and I with each other, so as to normally hold the jaw I2 in a closed position relative to the jaw I. The jaw I is hung on pairs of parallel levers I, fulcrumed at IG on the main frame A and connected by links I7 witha cam device for imparting a rocking motion to the parallel levers I5, to swing the jaws I and I2 into an operative position, as shown in Fig. l, or outrof the same (see Figs. lland 12), that is, whenever it is desired to cut the pile threads, as hereinafter more fully described.

In order to open the jaw I2 relative to the jaw I one of the links I3 ,is provided with an extension I8, connected by a link I with a cam device, which allows the open jaw I2 to close yand engage the ends of the pile threads b as soon as a tuft yarn frame D is in an operative position and the ends of.the pilethreads b have engaged the top surface of the lower jaw I (sec Fig. 1). The clamping device is also reciprocated intermittently in a transverse direction after the jaws are closed, and for this purpose any suitable means may be employed.

In order to comb out the ends of the pile threads b and to place the same'in 'proper position previous to clamping the ends between the jaws I2 and I, a combing device is provided, consisting of teeth N fulcrumed at N on the lower jaw I and extending up through recesses in the forward end of the ljaw I", so as to reach above the top surface of the jaw I and somewhat in ront of the forward end of the jaw I2. The teeth N alternate with the tuft yarn tubes G, so that when a tuft yarn frame D is carried into an operative position the free ends of the pile threads b, in passing on the top surface of the jaw I', also pass between adjacent teeth N, at the time the jaw I2 is in an open position. Thus the pile threads are kept separate and in proper alinement, and when the jaw I2 moves into a closed position,-the ends of the pile threads are clamped between the two jaws and are held in proper longitudinal alinement. As shown in Fig. 20, each.l of the teeth N is yieldingly mounted, that is, is provided with a rearward extension N, pressed'on by a spring N3 attached to the jaw I.

In order to beat in the wefts c and c andtheir pile loops successively, a beating-in device is provided, consisting essentially of sets of curved arms, each set having two arms O and O secured on a transverselyextending shaft O2 journaled on a lever Pifulcrumed at its lower end at P on the main frame A. On the shaft O2 is secured a worm-wheel Q in` mesh with a worm Q mounted to rotate with and to slide on the square end Q2 of a shaft Q3, journaled at its square end Q2 in a suitable bearing formed on the upper forked end P4 of the lever P. The other end of the shaft Q3 is mounted to turn in a bearing A carried by the main frame A, and on this end of the shaft Q3 is secured a bevel pinion Q, in mesh with a bevel gear-wheel Q mounted to rotate on a stud Q held on the main frame A. On the peripheral surface of the bevel gear-wheel Q5 is secured or formed a ratchet-wheel Q7, engaged by a pawl R pivotally connected with a lever R fulcrumed at R2 on the main frame A. The free end of the lever R rests on the peripheral surface ofla camwheel R3 in the form ofan eccentric secured on a shaft It4 receiving a rotary motion from the driving-gear of the loom. A spring R5 presses the pawl R, to hold the same in contact with the ratchet-wheel Q7. When the loom is in operation, the cam R3 imparts a swinging motion to the lever R which, by the pawl R, imparts Van intermittent rotary motion to the ratchet-wheel Q7 and gear-wheel Q5, so that the shaft Q3 is intermittently rotated, and this intermittent rotary motion is transinitted by the worm Q and worm-wheel Q to the shaft O2 and the sets of beating-in arms O and O held on the said shaft. An intermittent rotary motion is given to the arms O, O, once for each pick.

The sets of arms() and O extend between adjacent sets of ground warp threads a and a and the arrangement is such` that at least one of the said arms is always between adjacent pairs of ground warp threads a and a to prevent the ground warp threads rombecoming entangled and to hold adjacent pairs of warp threads sufiiciently far apart iorvthe proper entrance of the tuft yam tubes G, as previously referred to and hereinafter more fully explained. The arms O and O are also arranged in such a manner that the free -end of the outermost arm is always against the weit c or c beaten in last by this arm, to prevent loosening of the weft last beaten in by the pulls exerted on.the pile warp threads to be formed into a new loop (see Figs. 7 and 8), after the loop is completed (see Figs. 10, 11 and 12) and previous to and during the time the cutting mechanism cuts the pile threads.

The lever P is pivotally connected by a link P2 with a bell-crank lever P3 controlled by a suitable cam mechanism, to impart aninter'mittent swinging motion to the lever P, to shift the beating-in device and with it the worm-Wheel Q and worm Q bodily (see Fig. 6), vduring the time the arms O and O are rotated.

In order to cut off the pile threads b after a portion thereof has been used for forming the row of knots, cutting knives S and S are provided, normally standing in an open position and adapted to pass over each other, so as to shear off the pile threads, as will be readily understood by reference to Figs. Il and 12. The knives S and S are mounted on arms S2 and S3, fulcrumed on the main frame and connected by links S4 and S5 with suitable mechanism, ior imparting the desired motion to the knives S and S so as to cause the same to close and cut off the piles at the proper time and to then immediately open again and remain in this open position until the next set of pile `threads is to be cut off.

It is understood that the several mechanisms referred to are driven in unison from the driving-gear of the loom, so that the several parts operate synchronously, to perform the work in the proper sequence, and it is expressly understood that I do not limit myself to `any particular construction oi the mechanism required for producing the work in unison, as the same may be varied without deviating from the spirit of my ifnvention. l

The operation is as follows: When the 4several parts are in the position illustrated in Figs. 1 and 2, then a tuftyarn frame D has been moved from the endlessl carrier E into an operative position over the groundv warp threads, the tuft yarn tubes G now extending close to the jaw I of the clamping`device I, to lay the outer ends ofthe pile threads b onto the top of the said jaw I. The jaw I2 now swings into a closed position, so as to clamp the free ends of the pile threads b in position between the jaws I and I2, as plainly indicated in Fig. 3. The clamping device AI, after being closed, is shifted bodily in a transverse direction to bring the sidearms of the pile threads always to the same side of the connecting cross-bar of a Turkish knot. The amount oi movement given to the clamping device I in the direction mentioned is very little, approximately the distance between adjacent pile threads. After the clamping jaws are closed and the clamping device is shifted transversely, then the seats H and the tuft yarn frame D are caused to turn, to swing the tut yarn tubes G downward between adjacent pairs of ground warp threads a and a. During this downward movement of the tuft yarn tubes G the pile threads b are unwound from the tuft yarn spool F, as the tree ends of the pile threads are held in a clamped position on the clamping device I, and consequently the pile threads are drawn through the tuft yarn tubes and carried by the latterl down between adjacent pairs of ground warp threads a and As illustrated in Figs. 3 and 4, the tuft yarn tubes G swing downward between the beating-inarms O and O, and when the tuft yarn tubes G have reached the end of their downward swinging stroke (see Fig. 4),

then the tuft yarn tubes, with the pile threads, form open loops in the shed, to permit of carrying thel weft c through the open shed, it being understood that for this purpose a suitable weft-carrying device is provided, preferably in the form of a rod carrying av weft through the open shed in both directions, to cause the weft to consist of two weft threads, as indicated in Fig. 4.4 When the weft c has been passed through the open shed,

then the tuft yarn frame D is caused to rdck backward,

and in doing so the pile threads b are drawn completely around the weft c (see Figs. 5 and 6), and in order to draw the loop very tightly around the weft c an upward swinging motion is given to the swing-arms H (see Fig. 6), at the time the beating-in arms O and O are rotated and moved bodily to the right, so that the tuft yam frame D is out of the path of the advancing beating-in arm O and the latter is bodily return'ed and now acts on the weft c, to beat the 'same home (see Fig. 7). As previously stated, the beating-in device comes to a stop as soon as the end of the arm O reaches a final beatingin position. The heddles B and B now change. The swing-arm H is now again swung downward to the caused to rotate, to swing the tuit yarn tubes G downward into anotherloop-forrning position at the open shed, and then the second weit c ,similar to the weftjc, ispassed through the open shed (see Fig. 8).

v previous position, and then the tuft yarn frame D is again When this l has been done the tuit yam tubesG swing back into an beating-in position against the weft c, as indicated in Fig. 10. As soon as this has beenaccomplished the jaw I2 swings into, an open position, to release the free ends of the pile threads b and then the entire clamping device I swings to the left, as indicated in Fig. 1l and then the knives IS and S move toward each other to cut off the pile threads b and also the terminal ends previously held between the clamping jaws I and I2, so that a perfect Turkish knot is left on the wefts c and c, interwoven with the ground warp threads a and a. By reference to Fig. 12 it will be seen that the tut yarn rame'D has been swung upward a sufficient-distance so that after the knives S and S have lcut off the pile from'the pile warp threads b then the terminal-ends of the latter'exiend a distance beyond the free ends of the tut yarn tubes G, so that when this tuft yarn frame D is again brought into use at a-later period, then the said free ends can be again brought into proper clamping position between the jaws I and I2, as previously exv .plained. A final upward swinging motion is now given to the swing-arms H to return the tutt yarn frame to the endless carrier E, and then the swing-arms H are caused to swing downward a short distance, after which an intermittent traveling motion is given to the carrier E, to bring the next tutt yarn frame intoremoving position, and then the swing-arms H are swung up- Ward, to engage the neit tuft yarn frame and to carry the same downward intothe first operative position, shown in Figs. 1 and 2, and then the above-described operation is repeated. I

When forming the Persian knot (see Figs. 13, 14, 15 and 21) itis necessary to shift the tuft yarn frame D bodily forwardand backward, and for this purpose the swing-arms H and the rack J and its lever J2 are mounted on a separate frame T held to slide longitudinally iny suitable guideways arranged on the main frame A. A link 'T pivotally connects the frame T with a bell crank lever T2 fulcrumed on the main frame A and connected with a suitable cam mechanism or imparting the desired sliding motion to the frame T at the proper time. In making the Persian knot the pile threads b have their ends iirst clamped in the `clamping device I, as indicated in Fig. 13, then the tut yarn frame D is caused to rock, to swing the f tut yam tubes G downward, but at the time'the frame T has been moved into a right-hand end position, so that the tuft yarn .tubes G pass beyond the open shed, to allow of placing the weft c into the open shed l over the pile threads b, as indicated in Fig. 13. The

tuft yarn frame D is then rocked backward, for the tuft yarn tubes G to swing upward, and then the beating-in device is actuated, for the arm O to beat in the weft c, the frame T in the meantime moving to the left, so as to bring the tuft yarn frame D and the tuft yarn tubes G into the position shown in Fig. 14 The tuft yarn frame D is now rocked, to swing the tuftv yarn tubes G downward to form the loops in the lopen shed for the second weft c to pass through the open loops, and then the tuft yarn frame D is caused to return and the tuft yarn tubes G, in now swinging upward, cause the pilethreads to -be looped completely around the weft c, the lsaine as previously described with reference to Figs. 8, 9 and 10. After this has been done the ends of the pile threads are released by the clamping device I and then the knives S and S advance, to cut' Y ,ser

from the Persian knot it is necessary to insert the weft c in front of the tut yarn tubes G and the weft c an the time the loops are formed in the open shed, so that each pile thread extends under the weft c and'is then completely looped around the weft c in the manner of forming Persian knots. In forming the Persian knot it is not necessary to reciprocate the clamping device I bodily in a transverse direction, as above described in reference to the formation of the Turkish knot.

Although I have shown and described the fonnation of Turkish and Persian knots, it is evident that other similar knots may be made by the loom by re-arrangement of some of the parts, it being understood, however, that in -each case the pile threads are com-y pletely looped around at least one ofthe wefts.

It is understood that the heddles B and B the carrier E, the swing-arms H the tuft yarn frames D, the

.clamping device I and its rocking and transverse shifting mechanism, the, beating-in mechanism, 'the shuttle mechanism and the cut-off device all operate in unison, to produce the result above described, and I do not limit myself to any particular means for actuating the parts in unison, as the said means and the detail construction of the parts may be varied without deviating fromthe invention.
