Definitions

  • the filling motion under reference works with the same general principle as for instance, the multicolor filling motion as per the Swiss Pat. No. 465,524 by which, in a patterned sequence, one of the four different filling threads is guided from a waiting position to a pickup position.
  • the invention is characterized by the fact that two filling feeding fingers, each one mounted in its own pivot stud and having at its end a filling eyelet, are connected with each other for constrained operation and that the two filling fingers or their filling eyelets, respectively, can be brought alternately to the mutual filling taking position or out of this position, respectively, by a mutual cam control motion which is driven by the shuttleless loom.
  • FIG. I is a view of the inventive filling mixing motion seen in direction of filling insertion
  • FIG. 2 is a view as per FIG. I seen at right angles to the direction of filling insertion, partly in section, and
  • FIG. 3 is a portion of the view of the control cam, in section, showing the alternative for filling mixing in 2X2.
  • the filling fingers 1 and 2, FIG. 1 are each borne for rotation in a stud 4 or 5, respectively, said studs being fixed to a loomside 3, and arranged in such a way that one of the filling eyelets'6 or 7, respectively, provided in the fingers l and 2 (in FIG. 1 it is the eyelet 6) keeps a filling thread 8, which at this moment is not active in the weaving process, away from a filling depressor 9, whereby the filling eyelets 6 or 7 move in an arclike path to and from a mutual filling pickup position (in FIG. 1 at filling eyelet 7).
  • the filling finger 1 has a lever 10 with a forklike slide guide in which a sliding block 11 is guided and which is connected by a stud 13 fixed in the upright lever 12 of filling finger 2.
  • the block 11 is free to slide in guide 20 and the stud 13 is free to rotate in a bearing in the block.
  • the filling finger 2 is connected for operation from cam 16 by means of roller 15 being fixed to a further lever 14, said cam being positively driven by the loom by means (not shown) via shaft 17 so that the cam carries out a quarter rotation per pick of the loom.
  • the cam 16 shown in FIG. 1 will alternate the filling fingers l and 2 and thus alternately present the two filling threads, that is, make a filling change, after every pick of the loom.
  • the cam 16 as per FIG. 1 can be replaced in a simple way by another cam 19, FIG. 3, which will alternate the filling fingers l and 2, and thus present first one and then the other of the two filling threads only after every second pick of the loom.
  • a filling mixing motion for rapier-type shuttleless looms having at least two stationary sources of filling located outside the shed of a fabric being woven and reciprocating filling carriers functioning to draw filling from said sources as presented to one of the carriers to insert that filling as a completed pick, in a sequence of picks from one source and then from the other, characterized by, two separate pivot studs, two filling feeding fingers, one pivoted at each said stud and having a filling eyelet in each finger end so devised that the fingers may be moved to and from a position in which the eyelets occupy a substantially common feeding point, complementary arms, one for each finger and pivoted at the same stud as its finger, said arms having ends which overlap in their paths of movement and a common actuating means interconnecting said arm ends for moving one finger from the movements of the other alternately to and from filling feeding position, and cam and follower means to impart movement to one said feeding finger.
  • said common, actuating means comprises a sliding block, a slot in one arm for said block and a pivot pin carried by the other arm and passing through the block.
