Definitions

  • the present invention provides an apparatus for connecting a loom heald shaft to heald shaft tackle, comprising one or more bell-crank levers pivotally mounted on a beam supporting the heald shaft with one arm of the or each lever having an adjustable connection with the heald shaft and the other arm of the or each lever being connected with the tackle such that a tractive force produced by the tackle on said lever effects continuous readjustment of the connection between said lever and said heald shaft to eliminate play in said connection.
  • the adjustable connection between the or each double lever and the heald shaft consists of a cranked lever end having a wedge-shaped form extending substantially transversely to the direction of the tractive force and a block mountedon the shaft, the block having a wedge-shaped recess into which cranked lever end fits, whereby due to the wedgeshaped form there is an automatic adjustment of the surfaces of contact. This gives at any time a connection without play.
  • FIG. I is a diagrammatic side view of a loom heald shaft and heald shaft tackle.
  • FIG. 2 is a sectional view on a larger scale of a part of the apparatus shown in FIG. 1. shown),
  • FIG. 1 all secondary components, such as driving and lead-in organs, which are not important by way of explanation of the invention, have been omitted.
  • a loom heald shaft frame which is supported on a beam carrier 3 by a base 2.
  • the beam itself is suspended by springs 4 from the machine framework 5.
  • the heald shaft tackle 6 is arranged below the shaft and leads over guide rollers 7 to a jack lever 8 of a shed forming machine (not shown), for example, a dobby or treadle motion.
  • a bell-crank angle so that it lies transversely of the direction of a tractive force Z produced on the lever by the heald shaft tackle 6.
  • the end 13 has a wedge-like shape and engages in a correspondingly formed recess 14 of a block 15 of the shaft frame 1.
  • a hook 18 At the end of the arm 11 is a hook 18, from which the heald shaft tackle is hung.
  • the two arms 11 and 12 of the lever form an obtuse angle, so that the arm 12 being arranged vertically to the shaft frame the tackle 6 connected to the arm 11 exerts a turning moment on the lever 10 around the pivot 9. Said turning moment causes that under the tractive force Z the end 13 is pressed in the direction of arrow E into the recess 14.
  • any play between the double lever 10 and shaft frame even if wear and tear should have manifested themselves is annulled and automatic adjustability of the connection l3, 14 is obtained.
  • the recess 14 is in a block 15 which is accommodated in a hollow space 16 of the shaft frame 1.
  • the device as described can be employed with all negative dobbies.
  • Apparatus for connecting a loom heald shaft supported by a beam to heald shaft tackle comprising:
  • said beam is hollow and includes means defining an opening therein and wherein the lever passes through the opening in said beam into a hollow space in said heald shaft frame, said recess means being mounted in said hollow space.
  • Apparatus according to claim 1 including a pair of said bell-crank levers for each heald frame, wherein said recess means comprises a pair of opposed recesses in said heald shaft and wherein said adjustable projection means on said one arm of each of said levers extend in opposite direction from their respective lever arms into the respective one of said recesses.
  • Apparatus according to claim 1 including a spring for urging said lever into said recess means towards a means being pivotal with said one arm into and out' of engagement with said first connecting means about the axis defined by said pivotal mounting of said lever, said first and second connecting means comprising self-adjusting means for automaticallycompensating for wear occurring in said connecting means due to repeated relative movements therebetween.
