  • the filling extending carrier is depicted by numeral 13 and as is well known to those conversant in the weaving art, said carrier is fixed on the end of a tape 14, which in the performance of its intended function is caused to be wrapped about and unwrapped from a tape wheel (not shown) that is oscillatably driven within the housing 11.
  • a plurality of warp yarns are depicted in FIG. 1 by numeral 15 and by means of the usual harnesses (not shown) form warp sheds 16 (FIGS. 8, 9 and 10) into which a filling yarn 17 is inserted.
  • the loom reed is shown at 18 and provides the conventional means for beating-up the filling yarns to form the fabric identified by numeral 19.
  • the left hand temple is shown at 20 and serves to guide the fabric 19 as it is formed in a known manner.
  • the selvage forming apparatus is identified generally in FIG. 1 by numeral 21 and includes a support housing having a base portion 22 with upwardly directed sidewalls 23 and 24. This support housing, as shown disposed shaft 28. Intermediate the standards 26 and 27 shaft 28 has assembled thereon the hub portions of three single armed levers which are depicted by numerals 29, 30 and 31, and the arms thereof by numerals 32, 33 and 34, respectively.
  • sidewalls 23 and 24 are provided with integrally formed bearing support housings 35 and 36 having cap members 37 and 38, respectively, assembled thereon by means of screws 39.
  • a cam shaft 40 is rotatably supported by the bearing support housings 35 and 36 and as shown in FIG. 1 is caused to be rotated in the direction of the indicating arrow 41 by means of its connection as at 42 to a gear reduction box that is identified by numeral 43.
  • This gear reduction box 43 is driven by any suitable source of power on the loom by means of a shaft 44 which in the present case is connected in driving relationship with the looms cam shaft (not. shown).
  • cam shaft 40 That portion of the cam shaft 40 which traverses the distance between the bearing support housings 35 and 36 has fixedly assembled thereon for rotation therewith four cam members identified by numerals 45, 46, 47 and 48 (FIGS. 1,2,3 and 4). As shown in FIGS. 2 and 3 cams 45. 46, 47 and 48 are fixed on cam shaft 40 by means of a key 49 and set screws 50.
  • FIGS. 4, 5, 6 and 7 A filling yam gripping and a severing device are depicted generally in FIGS. 4, 5, 6 and 7 by numeral 51 and are carried on a common support bracket 52 which depends from the end of a bar member 53.
  • Support bracket 52 is attached to bar member 53 by means of bolts 54 and nuts 55.
  • Bar member 53 extends for substantially the full length of the support housing and is guided in a slot 56 (FIG. 1) provided in a guide block 57 which interconnects sidewalls 23 and 24 of said housing at its inner end or that end most remote from standards 26 and 27.
  • FIGS. 2, 3 and 4 show the guide block attached to the support housing by means of cap screws 58.
  • Ann 32 of lever 29 has a cam follower 60 rotatably assembled to the side thereof at a point intermediate its ends which by means of a coil spring 61 is adapted to maintain contact with the outer periphery of cam member 45.
  • One end of this coil spring 61 is attached to the guide block 57 by means of a screw 62 and the opposite end is attached by means of a bolt 63 to the bar member 53 at a point intermediate its ends (FIG. 4).
  • cam member 45 acts upon cam follower 60 so as to pivot arm 32 of lever 29 thus causing the bar member 53 to reciprocate.
  • This reciprocation movement carries the filling yarn gripping and severing devices toward and away from a position to act upon the end of an inserted length of filling and will be more fully described hereinafter. Additionally, this movement is effective in causing the filling yarn gripping and severing devices to be actuated by a fixed cam 64 that is disposed above and relatively close to said devices.
  • a cam support bracket 65 is shown assembled to sidewall 23 of the support housing by means of cap screws 66.
  • the upper portion of the cam support bracket 65 carries a pair of horizontally disposed stud members 67 and 68 (FIGS. 1 and In spaced relation to the cam support bracket 65 the stud members have the fixed cam 64 assembled thereon by means of nuts 69 and 70.
  • FIGS. 4,5, 6 and 7 show how the fixed cam 64 is caused to actuate the filling yarn gripper and severing devices.
  • the gripper consists of a plunger rod 71 that is guided by vertically aligned apertures provided in a pair of integrally formed bosses 72 and 73 disposed on the side of the common support bracket 52.
  • a coil spring 74 assembles on the plunger rod intermediate the bosses 72 and 73 and by means of a collar 75 said spring is partially compressed so as to bear against the upper side of boss 73.
  • This spring 74 provides a biasing force for the plunger rod 71 which continually urges it in an upward direction and maintains the upper end thereof in a position to be acted upon by the fixed cam 64 as the gripping device is caused to reciprocate with bar member 53.
  • the lower end of the plunger rod 71 terminates in the form of a laterally extending foot 76 and in timed relation to the weaving cycle is caused by the cam 64 and spring 74 to first move away from the underside of boss 73 and thence into engagement with it. This motion opens the gripper to receive the filling yarn and then closes it to grip said yarn.
  • the severing device is also actuated by the fixed cam 64 and in the same manner as the filling'yarn gripping device.
  • the severing device includes a plunger rod 77 that is guided for reciprocating movement in spaced and vertically aligned apertures.
  • the lower aperture is situated in a forwardly extending foot 78 which forms a part of the support bracket 52 and the upper aperture is situated in bar member 53 adjacent the point of attachment of said support bracket.
  • a coil spring 79 is positioned on the plunger rod 77 intermediate bar member 53 and the foot 78 and by means of a collar 80 said spring is partially compressed so as to bear against said foot 78.
  • This arrangement provides a biasing force for the plunger rod 77 so as to continually urge it in an upward direction and by means of a second collar 81 immediately adjacent to collar the limit of movement of said rod can be controlled.
  • the lower end of the plunger rod 77 is pivotably connected to the forward end of a cutting blade 82 the latter of which is pivotably attached intermediate its ends to the lower side of the support bracket 52 by means of a screw 83 (FIGS. 5, 6 and 7).
  • the filling yarn gripping and severing devices are so arranged that longitudinal movement of the bar member 53 in the direction of the indicating arrow 84 (FIGS. 1 and 4) first causes cam 64 to actuate the gripper device and thence the severing device which cuts the filling adjacent to the gripper.
  • the filling yarn 17 after its release by the filling extending carrier 13 is caught and held by a plurality of separate selvage threads 85 (FIGS. 1, 10 and 12) which are controlled in a known manner by harness means not shown.
  • FIGS. 10 and 12 the severed ends of the filling yarn are depicted by numeral 86 and are shown being held by the selvage threads 85. As the selvage threads are advanced they pass through a guide wire 87 (FIG.
  • This guide wire maintains the advancing selvage threads 85 in spaced relation to the edge of the fabric and they are then guided with the severed ends of filling yarn 86 through a rotating twister sleeve 89 (FIGS. 11, 12 and 13).
  • This twister sleeve has a centrally disposed aperture 90 through which the selvage threads 85 with the severed ends of yarn 86 pass and the diameter thereof is such that said severed ends are in frictional contact with the walls of said aperture. With the twister sleeve rotating continuously, the frictional contact of the severed ends with the walls of the aperture 90 is sufficient to slightly twist the selvage thread in the area of said twister sleeve so as to assure holding said severed ends of yarn.
  • the outside diameter of the twister sleeve 89 is recessed as at 91 (FIGS. 11 and 12) and provides a tracking area for rotating said twister sleeve by means of an endless belt 92.
  • the twister sleeve 89 is rotatably mounted in a hub 93 that forms an integral part of a bracket member 94 the latter of which attaches to the sidewall 23 of the support housing by means of a cap screw 95.
  • the bracket member 94 rotatably supports a pair of spaced idler pulleys 96 and 97 about which the endless belt 92 is adapted to pass.
  • the endless belt 92 is also in driving engagement with a pulley member 98 that is fixed on and which is adapted to rotate with the cam shaft 40 thereby providing the means for continuous rotation of the twister sleeve 89.
  • a means is provided for lowering the bar member 53 so as to permit the filling yarn gripping device to move the end of filling yarn held thereby to a position for presenting it to the inserting member the latter of which will be more fully described hereinafter.
  • This means for lowering the bar member 53 is controlled by cam member 46 and the single armed lever 30.
  • the arm 33 of lever 30 extends in a generally horizontal plane above cam member 46 and has a cam follower 99 rotatably mounted on the side thereof and at a point intermediate its ends.
  • This cam follower is adapted to maintain contact with the outer periphery of cam member 46 by means of a coil spring 100 which by means of a bolt 101 attaches to the end of arm 33. Extending downwardly the opposite end of spring 100 is fixedly attached to the sidewall 23 (not shown) of the support housing.
  • Bolt 101 also provides a means for attaching one end of an adjustable connecting rod 102 (FIGS. 1 and 2) to the end of arm 33.
  • connecting rod 102 is attached to the bar member 53 by means of the bolt 63 which serves to anchor one end of the coil spring 61 that continually urges said bar member in longitudinal direction toward the position to permit the yarn gripping and severing devices to act upon the filling yarn 17.
  • Cams 45 and 46 rotate continuously and are arranged in timed relation to the weaving cycle so as to first cause the bar member and the gripping and severing devices carried thereby to move horizontally to a position to receive, grip and thence sever the filling yarn adjacent its end. Continued rotation of these cams then brings a low point of cam member 46 into contact with cam follower 99 thereby causing arm 33 to be lowered by coil spring 101. As arm 33 is lowered connecting rod 102 is pushed downwardly and being connected to bar member 53 the latter is caused to pivot in a like direction within slot 56 of the guide block 57. The filling yarn gripping device is lowered simultaneously with the bar members 53 and the gripped yarn is then in position to be taken by the inserting member now to be described.
  • the inserting member or so-called selvage needle is identified in FIGS. 1, 8 and 9 by numeral 103.
  • This selvage needle is of arcuated configuration with the free end thereof defining a hook 104 for receiving the filling yarn from the gripping device and thence inserting the same into the warp shed.
  • the opposite end of the selvage needle is adjustably carried in a support block 105 the latter of which is fixed on the end of a horizontally disposed rod 106.
  • Rod 106 assembles in -a telescopic manner within the end of a second horizontally disposed rod 107.
  • a clamping block 108 assembled on the end of rod 107 the slotted end (not shown) of said rod can be compressed into clamping engagement with rod 106 at any position along the longitudinal extent thereof.

  • the end of rod 107 opposite the end to which the clamping block 108 assembles has a sleeve 113 (FIG. 3) fixed thereon by means of a nut 114.
  • the ends of this sleeve 113 are provided with aligned, radially extending and integrally formed web segments 115 and 116 between which a driving block 117 is positioned.
  • This driving block is pivotably attached to the lower end of the arm 34 of lever 31 by means of a bolt 118 and nut 119 (FIGS. 1 and 3) and by means to be described provides the means for longitudinal movement of rod 107.
  • the web segments extending in close proximity with the sides of the driving block 117 also permit the rod 107 to be oscillated while moving horizontally by a further means yet to be described.
  • Arm 34 of lever 31 extends in a generally downward direction and has rotatably assembled on the side thereof and at a position intermediate its ends a cam follower 120 (FIGS. 1 and 3).
  • This cam follower is adapted to track on the outer periphery of cam member 47 and ismaintained in contact therewith by means of a coil spring 121 one end of which attaches to arm 34 as at 122.
  • the opposite end of spring 121 is fastened to a vertically extending stud 123 (FIG. 3) that is fixed by means of a cap screw 124 to the base portion 22 of the support housing.
  • Cam 47 is rotated in timed sequence with the weaving cycle and arm 34 with its follower 120 is effective in reciprocating rod 107 to move the selvage needle 103 in a horizontal plane while simultaneously effecting oscillation thereof by the further means now to be described.
  • Rod 107 extends through a sleeve 125 that is supported for oscillating movement within the support housing.
  • a sleeve 125 that is supported for oscillating movement within the support housing.
  • One end of this sleeve is guided in a recess 126 (FIG. 3) that is provided in the flanged bushing 109 and adjacent its opposite end is provided with a circumferential groove 127 that provides a surface for its support by a yoked bearing member 128.
  • Bearing member 128 is fixed to the base portion 22 of the support housing by a pair of cap screws 129.
  • sleeve 125 is provided with a longitudinally extending recess 130 that serves as a track or raceway within which a key member, or as illustrated by the preferred embodiment, a roller 131 is adapted to travel.
  • This roller extends from rod 107 in a plane normal to the axis thereof and is attached to the latter by means of a bolt 132 and nut 133.
  • that portion of the sleeve opposite recess is also recessed for the greater portion of its length so as to provide clearance for the end of bolt 132 and nut 133 during longitudinal movement of the rod 107.
  • That end of sleeve 125 opposite the end guided in recess 126 is beveled as at 134 throughout: its circumferential extent and a portion of this beveled end is provided with gear teeth 135 (FIG. 2) that define a bevel gear segment.
  • Gear teeth 135 are in meshing relation with a second bevel gear segment 136 the teeth of which are integrally formed intermediate the ends of an arm 137 that forms a part of a bellcrank lever generally indicated in FIGS. 2 and 3 by numeral 138.
  • This bell crank lever is pivotably attached to sidewall 24 of and within the support housing by means of a threaded stud 139, washer 140 and a nut 141 (FIGS. 1 and 2).
