The harness-frames c are attached by cords orwires to horizontal top and bottom levers d, whoseopposite ends are connected by means of notchedjacks /and wires <j. The notched jacks are movedby pins on a pattern-cylinder n, so that their notch-es are engaged by either the lifter or depressor h i,to raise or lower the harness-frames. This loomhas also shifting shuttle-boxes, and the box-leveris moved bv a star cam. On the left of Fig. 3004, Fig. 3005. one of the jacks/ is .shown onan enlarged scale to exhibitthe notches more clearly. In another variety ofCromptons loom (Fig. 3005),vertical levers pivoted at theside are connected at bottomand top to the heddle or har-ness-frames by cords, andnotched jacks pivoted to suchvertical levers and controlledby a pattern-cylinder are en-gaged by bars which move thelevers and op
