Abstract

In a jack bar assembly for a straight bar knitting machine, a pair of jacks is used for each jack-operated sinker. A first jack mounted on a first pivot has a rear edge engaged by the slurcock. A second jack mounted on a second pivot has a rear edge engaged by a nose of the first jack and a nose which engages and actuates the sinker. An increased mechanical leverage provided by the cooperating first and second jacks permits reduction in the advance provided by the slurcock and faster smoother operation.
