Pick Finder Apparatus For Fluid Jet Looms

US Patent:
4474218, Oct 2, 1984
Filed:
Nov 22, 1982
Appl. No.:
6/443503
Inventors:
Randell F. Sample - Greensboro NC
Assignee:
Draper Corporation - Greensboro NC
International Classification:
D03D 5108
US Classification:
139 1E
Abstract:
The cam shaft of a fluid jet loom, which cam shaft normally operates the warp yarn harness frames, is disengaged from the machine drive mechanism by a clutch mechanism. The cam shaft is then rotated manually by the operator, as the machine drive is by-passed, to reposition the harness frames at a proper position such that faulty picks can be easily removed.
