Abstract
An apparatus for rapidly and simultaneously, coupling and uncoupling loom heald frames, of varying length, to and from their respective drive bell cranks. Each heald frame attaches to more than one head of a flexible tie-rod, which in turn, extends down to adjustment sliders which are connected to the drive bell cranks. During the heald frame coupling and uncoupling from a locking apparatus at the head of the flexible tie-rod, two tilting jaws keep all of the flexible tie-rods in a rigid vertical position.
Claims3
A system for rapid assembly and disassembly of heald frames to and from the drive bell cranks of a loom, comprising:
- a plurality of flexible tie-rods having opposite ends, wherein one end of each of said tie-rods is hingedly connected to a bell crank and the other end has a head with a nitch therein,
- a guide on the bottom side of the heald frames for coupling and uncoupling the heald frames to and from said tie-rod heads by movement therebetween, wherein said guide has a stop for engaging said tie-rod heads to limit the coupling movement,
- a locking mechanism for said tie-rods having balls housed within said guide and springs within said guide, urging said balls from said guide until said tie-rods reach said stop during coupling, whereupon said balls engage said nitches in said tie-rods to interlock said tie-rods and the heald frames, and
- a pair of moveable jaws located on opposite sides of said tie-rods normally spaced therefrom and wherein said jaws are caused to rotate by an actuation means are movable into contact with said tie-rods to maintain said tie-rods in a vertical position when coupling and uncoupling occurs between said guide and said tie-rods, to thereby allow for the rapid assembly and disassembly of the heald frames and said tie-rods.
