Definitions

  • the filling needle has a bifurcated end defining a pair of parallel vertically aligned legs, each lying in a horizontal plane.
  • the uppermost leg at its free end has an eye through which' the filling thread extends and the lowermost leg is also bifurcated defining a long and a short finger.
  • the filling needle is slidably mounted in a horizontal plane in an upright support that is free to pivot about its axis and the needle is reciprocated in manner also to cause the support to pivot about its axis and the support is positioned on one side of the web to be formed, with the filling needle adapted to be movedthrou-gh the shed, formed in the web in conventional manner.
  • a thread deflector which has a portion thereof extending substantially parallel to the needle in a plane slightly above that of the latter and on the side thereof associated with the longer finger of the bifurcated leg.
  • the deflectorat the end of such parallel portion is downwardly inclined and then extends laterally beneath and across the needle, past the other side thereof.
  • the filling needle is designed to coact with a knitting needle extending parallel to the Web on the other side thereof in such manner that a portion of the filling thread spanning vertically betweenthe ends of the filling needle will be engaged by the hook end of the knitting needle when the latter is straddled by the legs of the filling needle, so that thereafter the knitted selvage may be formed in conventional manner.
  • Fig. -1 is a partial side elevational view of the loom
  • Figs. 2, 3 and 4 are top plan views showing the filling needle in various operative positions
  • Figs. 5 and 6 are top plan views on an enlarged scale showing the filling needle coacting with the knitting needle
  • Fig. 7 is. a view similar to Fig. 5 showing the .knitting needle aftera loop has been formed
  • Fig. 8 is a detail perspective view showing the filling needle coacting with the knitting needle
  • Fig. 9 is a-detail perspective view of the filling needle mount and deflector.
  • loom comprises take-up rollers (not shown) which draw the finished web 12 that is formed from warp threads 13 fed from suitable supply rolls (not shown) through the eyes of conventional heddle plates 14 to form a shed is.
  • a disc 16 Positioned laterally of the web 12 is a disc 16 mounted on a vertical'shaft 17 rising from the bed 20 of the loom and driven in any suitable manner so as to rotate in a clockwise direction. Rising from disc 16 adjacent its periphery and rotatably mounted thereon is a rod 18 which carries a block 19 at its upper end that has a transverse bore therethrough.
  • a weft filling needle 22 Positioned in said bore and secured therein-as by set screws 21 is one end of a weft filling needle 22 which is slidably positioned in the transverse bore of a block 23 mounted on the upper end of an upstanding rod 24 rotatably mounted on the bed 20 on the same side of the web as the shaft 17.
  • a knitting needle 28 Cooperating with the-filling needle 22 is a knitting needle 28 which extends parallel to the web on the side thereof remote from disc 16.
  • the needle 28 which is carried in a reciprocable carriage block 29, is of conventional type having a hook 31 atone end and a pivoted latch bar 32 adjacent said hook end.
  • a rigid wire 34 (Fig. 6) that serves as a guide for the other edge of the web 112 extends parallel to the warp thread that defines such edge.
  • a reed 35 is provided forbeating up the filling toward the fell of the shed in conventional manner.
  • the filling needle 22 has its free end bifurcated as shown in Fig.8 to define a pair of parallel legs 36 and 37, the end of the uppermost leg 36 having a thread opening or eye 38 therethrough.
  • the lowermost leg 37 is also bifurcated defining a long and a short finger 41, 42, the space 43 therebetween being directly beneath the opening 38.
  • the block 23 mounts a deflector or throw over member 45 which extends laterally therefrom adjacent the end of the transverse bore, through which the needle 22 extends.
  • the deflector member has a portion 46 extending substantially parallel to the needle 22 in a plane slightly above that of the latter and on the side thereof flector will position a lengthofthread to span across associated with the longer finger 41 of the bifurcated leg 36;
  • the deflector at the end of such parallel portion is downwardly inclined as at 47 and then extends laterally beneath and across the needle as at 48 past the other side thereof.
  • the deflector member is a length of reversely bent stiff wire having both of its ends secured to the block 23. 7
  • a thread guide 51 which comprises a bracket having a horizontal leg 52 with an opening 53 at one end through which the filler thread F extends from a suitable supply roll (not shown).
  • the filling thread is laid in the shed by the action of the needle 22.
  • the knitting needle 28 is then retracted from the position shown in Fig. 6 to the position shown in Fig. 7, by movement of its carrier 29, to cast off the previous loop A of filling which has previously moved below the latch.
  • the open latch 32 moves therethrough, closes the latch 32 so that the loop will pass over the portion of thread engaged by the hook so that such portion will also form a loop.
  • the thread will extend from the thread guide 51 through opening 38 in the upper leg 36 of the filling needle 22 then beneath the deflector 45 at the outer end 47 thereof to the web 12 as at C.
  • the outer end of the needle 22 will also be substantially retracted as shown so that the deflector extends beyond such end.
  • the reeds will be retracted as shown in Fig. 4 so that the filling needle will be free to again move through the shed.
  • the knitting needle will slide through the loop previously formed which is engaged by the hook and this will cause the latch 32 to open (-Fig. 5) and as the knitting needle 23 extends further, the loop will completely pass over the latch 32 and the hook end 31 of the needle is free to receive the span carried by the filling needle. Thereafter the cycle repeats.
  • the web will be Woven in conventional manner, the action of the filling needle 22 and the knitting needle 28 providing a knitted selvage at one edge and a loop at the other edge as shown in Fig. 7, the edge wire 34 supporting such other edge as the filling thread F is passed around the associated warp thread 13.
  • the movement of the filling needle, knitting needle, reeds and heddle plates are properly correlated in conventional manner to avoid interference.
  • the filling needle 22 enters the shed 15 at the rear, moves forward therein and moves out at the forward end and the knitting needle 28 is moved forwardly to be engaged by the span of thread carried by the filling needle 22 when the latter has passed through the shed and is moving outwardly therefrom.
  • a filling needle slidably and pivotally mounted on one side of the shed, means on the end of said needle slidably to mount a vertical span of thread, a knitting needle on the other side of the shed, said needle having a hook end, means for swinging said filling needle about its pivotal mount so that the end of said filling needle enters the wide end of the shed and is projected therethrough to the opposite side thereof and is retracted in a path adjacent the fell of the shed and is advanced along the side of the shed on which the filling needle is mounted to a point adjacent the wide end of the shed, said path being such that the vertical span of thread carried by said filling needle will. be engaged by the hook end of the knitting needle, said hooked needle being reciprocably mounted to knit loops in the thread.
  • shed forming means a filling needle, a mount slidably and pivotally supporting said filling needle on one side of the shed, said needle having a bifurcated end defining a pair of vertically aligned legs, the free end of the upper leg having an opening for filling thread and the free end of the lower leg being bifurcated to define a pair of fingers lying in the same plane and defining a space beneath said opening, means to position the thread extending through said opening between the fingers of said lower leg to form a vertical span of thread between said legs, a knitting needle on the other side of the shed, said needle having a hook end, means for swinging said filling needle about its pivotal mount so that the end of the filling needle enters the wide end of the shed and is projected therethrough to the opposite side thereofand is retracted in a path adjacent the fell of the shed and is advanced along the side of the shed on which the filling needle is mounted to a point adjacent the wide end of the shed, said path being such that the vertically aligne
