Definitions

  • Another object of the invention is to provide a harncss arrangement which can be reciprocated at very high speed.
  • the present invention provides a single reciprocated supporting rod, to which at least two heddle rails are secured, extending perpendicularly to the supporting rod.
  • the supporting rod is directly engaged by the drive means and reciprocated in a vertical direction, also serving as a guide rod, and the possibility of jamming of a harness frame in guide means is eliminated.
  • a supporting rod consisting of a profile bar is used so that the weight of the supporting rod is reduced while the supporting bar nevertheless has high rigidity. It is advantageous to mount the heddle rails on the supporting rod by clamping attaching means, so that the worn heddle rails can be exchanged.
  • the drive means include an oscillating cam follower lever engaging a first portion of the supporting rod for moving the supporting rod and heddle rails in a first stroke, and a second portion engaged by a spring.
  • the first and second portions are spaced transversely to a plane passing through the supporting rod and the heddle rails so that a turning moment acts on the supporting rod and the heddle rails against the force exerted by warp threads moving through the heddles, so that friction is reduced.
  • FIG. 1 is a front view of an embodiment of the invention
  • FIG. 2 is a side view of the harness arrangement illustrated in FIG. 1;
  • FIG. 3 is a fragmentary schematic front view illustrating a modification of the embodiment of FIG. 1;
  • FIG. 4 is a fragmentary schematic plan view of the modified embodiment of FIG. 3;
  • FIG. 5 is a fragmentary schematic front view illustrating another modification of the embodiment of FIG. 1;
  • FIG. 6 is a fragmentary schematic plan view of the modification shown in FIG. 5.
  • a vertical supporting rod 1 which has U-shaped cross section, supports two horizontal heddle rails 2 connected by heddles 4 which have loops at the ends through which the heddle rails 2 pass.
  • the upper heddle rails 2 is slightly wider than the lower heddle rail 2 so that the upper loops of the heddles 4 surround the heddle rails 2 almost without play.
  • the center portions of the two heddle rails are secured to the supporting rod 1 by U-shaped clamps 3 and screws, not shown, permitting a detachment of worn heddle rails 2, and replacement by new heddle rails.
  • the clamps 3 are located within the opening formed by the legs of the U-shaped supporting rod 1.
  • a pair of guide bars 10 is provided with longitudinal grooves in which the free ends of the heddle rails 2 are
  • the lower end of supporting rod 1 carries a bracket 5 with lateral walls 5a between which pins 6 and 6a are mounted.
  • a spring 9 is secured to pin 6a and to the base 15, and since the pins 6 and 6a are spaced from each other transversely to a plane passing through the supporting rod 1 and the heddle rails 2, the forces applied on pin 6 by the driven lever 7 and on pin 6a by the spring 9, produce a turning moment tending to turn supporting rod 1 with heddle rails 2 and heddles 4 in a direction which is opposite to the direction of the force applied to the heddles 4 by warp threads 14 moving through the heddle eyes in the direction of arrow X. In this manner, friction, particularly of the free ends of the heddle rails 2 in the vertical guide bars 10 is reduced.
  • FIGS. 3 and 4 show a modified construction in which instead of the grooved guide bars 10, several guide blocks l0, 10" with grooves 100 are provided. By guiding the outer ends of the heddle rails 2, vibrations of the supporting rod 3 are prevented even at high operational speeds.
  • FIGS. 5 and 6 The modification of FIGS. 5 and 6 includes vertical slide rods 11 secured to the ends of the two heddle rails 2 and being guided in corresponding grooves 12a of guide members 12. Slide rods 11 are preferably detachably secured to the heddle rails 2, and increase the rigidity of the heddle rails 2.
  • a connecting rod 13 can be secured to the heddle rails 2 and increases the stiffness and rigidity of the heddle rails 2.
  • shaft rotates cam 8 so that follower lever 7 is reciprocated and raises by engagement of pin 6, supporting rod 1 with heddle rails 2 and heddle rails 4 so that the warp threads passing through the eyes of the heddles 4 are raised to form a shed.
  • the spring 9 pulls bracket 5 with supporting rod ll down so that the heddle rails 2 also move downwardly with heddles 4 and the warp threads 114 passing through the same.
  • a slight turning moment in clockwise direction is exerted by lever 7 and spring 9 on bracket 5 and supporting rod 1 to urge the heddle rails 2 toward the right as viewed in FIG. 2 to oppose the pull of the warp threads 14 passing through the eyelets of the heddles 4 in a direction of the arrow X.
  • a harness arrangement for a loom comprising a single supporting rod; at least two heddle rails extending perpendicularly to said supporting rod spaced from each other along said supporting rod, and having cen' tral portions secured to said supporting rod and outer ends; heddles extending between said heddle rails and having end portions attached to said heddle rails; a pair of elongated stationary guide means parallel with said supporting rod and slidingly engaging said outer ends of said oajsKd heddle rails for guiding said heddle rails with said supporting rod; drive means connected with said supporting rod for reciprocating said supporting rod in longitudinal direction with said two heddle rails while said outer ends thereof are guided by said stationary guide means, said drive means including a driven reciprocating member engaging a first portion of said supporting rod for moving said supporting rod in a first stroke in one longitudinal direction, and a spring means engaging a second portion of said supporting rod for moving said supporting rod in a second stroke in the opposite longitudinal direction, said first and second portions being spaced transversely to a
  • Harness arrangement as claimed in claim 1 comprising two slide rods secured to said ends of said heddle rails and being guided by said elongated guide means during reciprocating movement.
  • Harness arrangement as claimed in claim 2 wherein said elongated guide means are guide bars having longitudinal grooves slidably receiving said slide rods for guiding said heddle rails and supporting rod during reciprocating movement.
  • Harness arrangement as claimed in claim 1 wherein said end portions of said heddles are loops receiving said heddle rails; and wherein at least the loops on one of said heddle rails fits on said heddle rails so that said heddles reciprocate with said heddle rails almost without play.
