Definitions

  • ABSTRACT A forked link comprises two prongs, each of which has a bearing eye
  • the bearing eyes are coaxial and adapted to receive a pivot.
  • a screw drive is disposed between and operatively connected to said prongs and operable to cause said prongs to spread said bearing eyes apart and to move them toward each other.
  • the heddle frame linkage of a weaving machine is divided into pivotally connected members.
  • One member of the heddle frame linkage terminates in such a hinge fork and the next member of the linkage has an eye which receives the pivot pin between the prongs of the fork.
  • a self-aligning or ball bearing may be provided here, which carries two axle journals instead of one pivot pin.
  • the members of the heddle frame linkage must be accommodated in the space allowed for each heddle frame. 'For this reason, the pivoted forks must be as thin as possible and must have no parts which protrude in the direction of the pivotal axis so that the pivot pin or the like cannot be locked against an axial displacement by split pins, circlips or the like.
  • the two prongs are adapted to be spread apart and drawn toward each other by means of a screw drive which is disposed between the prongs.
  • a screw drive which is disposed between the prongs.
  • the screw drive is operated in the opposite sense so that the prongs are drawn toward each other and hold the pivot pin or the like between them; it will be sufficient if the pivot pin has recessed ends journaled in the bearing eyes of the prongs.
  • the screw drive comprises two bushings which are fixed in respective prongs of the fork and coaxially aligned and provided with oppositely handed female screw threads, and an operating wheel which is disposed between the bushings and has two screw-threaded stub shafts screw-threaded in respective ones of the bushings.
  • the prongs of the fork Upon a rotation of the wheel in one direction or the other, the prongs of the fork will be spread apart or drawn together.
  • the thickness of the operating wheel may be much smaller than the distance between the prongs of the fork so that the screw threads in the bushings and on the stub shafts will be of sufficient length. Nevertheless such screw drive may be accommodated even in a very narrow forked link.
  • the operating wheel is adapted to be locked in position by an angled free end portion of a U-shaped spring inserted into a bore in the periphery of the wheel.
  • the two prongs of the fork are resiliently biased toward each other in a known manner so that, when the prongs have been drawn toward each other, a snug engagement of the prongs with the shoulders of the pivot pin or with the bearing is ensured.
  • FIG. 1 shows a fork link, partly in section
  • FIG. 2 is a side elevation showing the fork on a larger scale.
  • Forked link 3 included in the heddle frame linkage of a-weaving machine comprises two prongs l and 2.
  • a screw drive is provided between the two prongs 1 and 2 and is operable to spread the prongs apart and to draw them toward each other.
  • the screw drive comprises two coaxially aligned bushings 4, 5 which are fixed in respective prongs l and 2 and provided with oppositely handed screw threads, and an operating wheel 8, which is disposed between the bushings 4, 5 and has two screw-threaded stub shafts 6, 7 which are screw-threaded in the bushings.
  • the hinge fork Upon a rotation of the operating wheel 8, the hinge fork will be opened or closed by the action of the oppositely handed screw threads, depending on the selected sense of rotation.
  • a pivot pin 9 for connection to another part of the linkage can be embraced by the prongs from the outside and can be held in position between said prongs.
  • the pivot .pin has reduced journals 10 which extend into the bearing eyes 11 of the prongs.
  • the two prongs 1,2 are resilient and biased toward each other so that, when drawn toward each other in the absence of the pivot pin 9, they assume the position which is indicated in dotted lines in FIG. 1.
  • a U- shaped spring 12 is provided, which snaps into a bore 13 inthe periphery of the operating wheel 8 to lock the same against an undesired rotation.
  • a heddle frame linkage comprising 1. a pivotal connecting means, and
  • the bearing eyes being coaxially aligned and b. the prongs being adapted to be spread apart and moved towards each other in the direction of the axis of the bearing eyes, and
  • a screw drive disposed between, and operatively connected to, the prongs, the screw drive being operable to spread the prongs apart and move them towards each other.
  • v 4 adapted'to be inserted into a peripheral herein the operating wheel for locking the wheel in position.
