Abstract
A spreader tool for the individual coupling and decoupling of heald shafts to or from the respective drive rods or shaft pulls of a heald loom is constructed to be inserted into a gap between two connecting spring sections from above the loom healds for spreading the connecting spring sections apart. The tool has two jaws that are normally biased into their closed position by a spring for insertion into the gap and are then spread apart by a cam drive or the like. The assembly and disassembly is thus greatly facilitated and the time previously required for this type of work has been substantially reduced.
Claims10
A spreader tool for the individual coupling and decoupling of a heald shaft to or from respective drive means in a heald loom, comprising a first spreader jaw and a second spreader jaw forming a pair of spreader jaws, means for journalling said spreader jaws to each other at their ends opposite to a spreading end of said spreader jaws, said journalling means permitting rotation of said spreader jaws about a common axis, means for normally biasing said spreader jaws into a jaws closed position, and drive means for opening said spreader jaws in a direction opposite to an effective direction of said biasing means, said drive means comprising a drive cam (11), a handle secured to said drive cam, and means for mounting said drive cam between said spreader jaws, whereby rotating said handle rotates said drive cam to move said spreader jaws away from each other.
