The movement of the weft carrier draws addi _ tional yarn from the cop through the member with which it ,has a running connection and si 20 multaneously loops such yarn and inserts it into a shed formed by the manipulation of warps by usual shedding‘ mechanism. My invention is particularly applicable to looms raveling by the bight of the hairpin. The mech anism may, however, be so operated as to lay one leg of .a hairpin in the upper shed andthe other leg of the hairpin in the lower shed of two super posed warp sheds. In such case, the bights of 10 adjacent hairpins may be at the same or opposite selvages, and the free ends of the wefts may be ' secured by weaving a doup or leno selvage. In the preferred embodiment of my invention, the mechanism on each side of the loom for 15 stretching the weft yarns in the paths of the weft carriers operating on such side of the loom com prises a pair of stationary grippers, which are po sitioned in planes on opposite sides of the paths of the weft carriers in their movements into the 20 sheds. Yarns are led from a compact supply ‘of weft yarn to such grippers through eyes in the ends of lever arms which may be reotilineally for the production of fabrics having picks lying in . movable relative to one another and are oscil 25~ different vertical planes, such as plush made on latable about an axis so as to carry sections of 25 the double plush principle or friezes having ground the threads running through the eyes to the picks and loop picks spaced from one another. opposite sides of the paths of the weft inserters A single weft carrier may be employed and may from the gripper by which such threads are then insert wefts positioned by‘one or, a pluralityof' held.

By removing the bolts 3'8’ and 38’, the levers 38 and 48 may be readily detached from one another and the link 31 on one side of ‘the loom may be connected with the lever 38 alone and the link 31 on the opposite side of the loom may be connected with the lever 48 alone when it is desired to feed but one thread from each side 30 of the loom. When, however, a pair of wefts are to be fed from each side of the loom weft threads 52 and 53 are laid from the cops 54, mounted on stationary supports I’ (Figure 1) through tension devices 55 and guides 56 and are threaded through the eyes 58' and 5E and have their tips gripped byone or the other of a pair of gripper mechanisms on opposite sides of the paths of the weft carriers. The levers 38 and 48 are normally biased by 40 a spring 4211 toward the'positions shown in full lines in'Fig. 5 and in Figs. 4, 6, and '7, and when the levers 38 and 48 are in such positions the tips or ends of the threads 52 and 53 are held in a gripper comprising the ?xed serrated jaw 57 and the rocking serrated jaw 58 journalled on a shaft 59 in the bracket 68. A guide pin 68' and‘ weight tension device 60" are preferably pro vided adjacent to the jaw 58 to better control in closed position by a plunger ll pressed by a spring 18 Whose tension is adjustable by means of the threaded plug 19 (Figs. 5 and 8). The op posite end of the lever 16 contains an elongated 25 slot 88 for the reception of a pin 8! ?xed in the link 82 which is pivotally connected with the ful crumed lever 33. When the cam 29 rocks the lever 33, the link 82 rocks the lever ‘I6 to open the jaw 13 against the pressure of the spring '58. 30 The cutter 66 and gripper .13 have adjacent thereto guide pins and tension devices similar~ to the pins 68' and tension devices '68". In the preferred cycle of operations of the weft positioning mechanism described, begin ning with the positions shown in dotted lines in Fig. 5, it may be considered that lengths of the yarn 52 and 53 have just been inserted as loops and straightened out in the sheds as straight lengths each forming one leg of a hair-pin-like 40 pair of wefts in the sheds of the fabrics being woven and that the yarns 52 and 53 are held by the gripper jaw 13 to prevent withdrawal of the picks just laid when the next succeeding loops are being drawn out. When the rotation of the cam 26 drew the levers 38 and 48 from the po sition shown in full lines to the position shown in dotted lines in Figure 5, the lever 48 and the the thread; the Weight tension device being opened by the jaw 58 through a pin 68a on the yarn 53 carried thereby were forced downwardly weight tension device 68", which when it has served its purpose is lifted by the further move thread 52 lying between the jaw 13 and the eye ment of the jaw 58 engaging the pin 68a. The jaw 58 has ?xed thereto a lever 68 (Fig. 10) through which the jaw is biased toward theclosed or gripping position by a plunger ‘62 pressed out wardly by a spring 63 whose tension is adjustable by means of a threaded plug 64. The opposite end of the lever 6| is engaged by the tail of the curved lever 3| and rocked thereby at desired able in vertically spaced planes to carry» the weft yarns 52 and 53-into the sheds of the fabrics or fabric. The movements of the weft inserting de intervals to open the jaw 58 (Fig. 10), against in the plane of the eye 58, and both threads 52 , and 53 are under the open jaw 58 and cutter 66 by the cam face 44' so that the thread 53 was 50 tension device. As the thread is under some ten - looped under the guides .83 and 84 as the eye 5| sion when held by the gripper, there may be of the lever 48 moved horizontally past the guides , some tendency toward a “snap” action when the in moving fromthe full lineposition to the dotted _ gripper is released, which tendency of the thread line position (Fig. 5) and hence the yarn 53 lies CH Li is momentarily restrained by the action of the; in a plane vertically spaced from the stretch of the action of the spring 63 when the thread carrying arms 38and 48' have been shifted by the mechanism described to the full line position ‘ shown in Fig. 11. A cutter is mounted in the bracket 68 adjacent to the gripper jaws 51 and .58 and comprises a ?xed plate 65 and a rocking blade 66 journalled on the shaft 59 and-pressed along the same by 75 a coiled spring 61 (Figs. 4 and '7). The cutter 50. Weft inserting devices 85 and 86 are mov vices into the sheds draws thread from the cops 54 through the eyes 58 and 5| into loops within the sheds. During the inward movement of the weft, inserting devices, the lever 48 is elevated by. its spring 42 until its eye 5| is substantially 65 (Fig. 11). When loops of su?icient length have been drawn, the cam 29 opensthe jaw 13 simul taneously with the ‘closing of the jaw 58 and 70 cutter 66 by the respective arms 6| and 68. This severs the thread beyond the gripper 58 and per- I mits the severed ends to be inserted into the sheds of the fabrics.

The slides H1 and H8 are held in draw out a substantially taut thread between the gripper 68 and the eye 50 and to loop a section of the thread 53 around the guides 83 and 84 as a result of the downward motionof the lever 40 while turning about the fulcrum 39. When the levers 38 and 40 reach the dotted line position 10 shown in Fig. 11, the weft inserting devices are again operated to draw loops partially into the sheds of the fabrics. Thereupon the spring 42 elevates; the shaft 40 from its dotted line posi tion shown in Fig. 11 to its full line position shown 15 in Fig. 5. In the latter position the yarns 52 and 53 are drawn beneath the jaw ‘I3 by the continued movement of the weft inserting mechanism. When a loop of sufficient length has been drawn, the jaw ‘I3 is'closed and the jaw 53 is opened,_ thereby permitting the free end of the yarn which had been held by the jaw 58 to be drawn into the shed.

The slides III and H8 have ?xed thereto the bands or straps I26 and I2‘! which are movable in slide-ways I28 and I29 formed in the curved tracks I30. These straps or needles I26 and I2'I have sufficient ?exibility to conform with the curvature of the slide-ways I26 and I21 without fatiguing, but su?icient rigidity to support them selves and weft carriers in-substantially horizon- . - tal planes when extruded‘ from the slide-ways by the oscillations of the arms IIO.

As the cutter 66 cuts yarn lengths equal to double the width of the fabric, the second picks formed from a single and the weft loop in such case may be drawn out at the selvage of the fabric opposite that at which they were inserted, or may be of only sufficient length to reach from one selvage to the cut length vmust necessarily extend from one sel While, as above set forth, my improved loom vage to the other when the bight of the hairpin 40 mechanism is operable in a great variety of se is released by the opening of the gripper 13. It quences, the following is illustrative of a desirable ‘will therefore be seen that when one leg of the mode of operation thereof for the production of hairpin-like pair of wefts has been inserted into a shed asa loop and is being straightened out in pile fabric on the double plush principle. In the manufacture of double pile fabric, a the shed as a result of the release of its free other. _ - 45 pair of ground warps for, the upper ground fabric, a pair of ground warps for the lowerground fab ric, and one or more pile warps are threaded through the heddles ‘I and operated by the loom harnesses in any usual manner. A pair of threads 50 52 and 53 are threaded in the eyes of the respec tive levers 38 and 48 on each side. of the loom and the arms “0 are adjusted so as to extrude the needles I26 and I21 from their slide-ways su?iciently to cause their complementary heads 55 200 to meet in transfer position midway.0f the loom. The harnesses are operatediso as to form a shed from the ground warps-of the upper fabric and a shed of the ground warps of the lower fab 60 ric and to change the sheds after each weft car rier insertion. _ ' If the weft mechanism now be regarded as so positioned that a yarn 52 is stretched from the jaw 58 to the eye 58 of the lever 38, and a yarn 65 53 is stretched from the jaw 58 around the guides 83 and 84 to the depressed eye 5| of the lever 48 on each side of the loom, the extrusion of the needles I26 and l_2'| from the slide-ways on each side of the loom will cause the head 200 on each 70 needle I26 to carry a loop of a yarn 52 intothe' shed of the upper fabric and will cause the head 280 on each needle I21 to carry a loop of a. yarn 53 into the shed of the lower fabric. When the complementary heads meet in the 75 center of the fabric, the loop inserted in the upper end'by the gripper 53, the drawing of too much 46 yarn into the shed for a single weft is prevented by the engagement of the yarn by the gripper 13. When the ?rst leg has been completely in serted, it is important to prevent it being wholy or partially withdrawn by the application of a pull thereto in drawing into a subsequent shed a sequential length of yarn in the form of a loop which is straightened out in the shed to form '50 the second leg of the hairpin-like pair of wefts. Consequently, the gripper ‘l3 retains its hold on 55 the ‘yarn until the second loop has been drawn into the shed and then releases the yarn so that such second loop may be straightened out and the bight drawn up close against the fabric sel vage. . . v When the heads 208 have been all retracted from. the sheds, the two legs of weft which have been inserted from opposite sides in. each shed are beaten up by the lay and the harnesses op~ erate the heddles to form a new shed in each fabric. Meanwhile, the arms 33 and 40 are movedby' the actions of the cams 26 across the paths of the heads 23', and such movements of the levers 38 and 43 draws off yarns from the cops and lays 70 a section of yarn 52 from each jaw 13 to each eye 50 and lays a section of yarn 53 from each jaw 13 around each pair of guides 83 and 84 to each eye ‘I.

Shortly before the com plementa'ry heads come into transfer position, the jaws ‘I3 are .opened so that the bights be tween the previously laid weft legs and the new ly formed loops may be drawn by the heads close pact supply, forming ‘a weft loop therefrom and inserting it in a shed and the other of said car riers drawing through said shed a part of the yarn loop formed by said first yarn carrier, and loom mechanism independent of the sheds for gripping said yarn and preventing withdrawal of an inserted pick during the stretching of a 10 subsequent” weft length in the path of said'?rst 10 up‘ against the selvage 'of the fabric. As the heads again approach their transfer positions, the blades 66 are operated to cut the threads, and jaws 58 are simultaneously op erated to grip the ends of the threads connected 15' with the levers" and 40. Upon the retraction of the heads, the cut ends of the loops are drawn to the opposite side of the fabric to complete the other leg of a hairpin weft, which is then beaten up, and the sheds changed as before described.
