US Patent 3,963,060, granted June 15, 1976 to Raymond F. Dion of Greensboro, NC, and assigned to Crompton & Knowles Corporation. It describes an improved shuttle drive for a narrow ware loom in which a vertically moving batten carries rows of shuttles. Switches detect which side of the warp shed the active shuttle is on, and air-cylinder actuators controlled by solenoid valves and timer cams move it across. The scan includes a USPTO web-database printout with abstract, claims and citations, plus the patent drawing sheets (Figs. 1-8) and the printed specification and claims.
