594,662. Automatic shuttle-changing in looms. LLOVERA, F. Oct. 10, 1944, No. 19487.. Convention date, Jan. 25. [Class 142 (iii)] In a shuttle changing mechanism of the kind having a magazine 16 mounted on the slay, the working shuttle 20 operates from the lower cell of the shuttle box and a spare shuttle 21 occupies the upper cell. Shuttle changing is effected by a member 58 moving into the path of a cam track on a mutilated gear 36 so that the gear meshes with a pinion 43 and rotates an eccentric 44 half a turn; this depresses the shuttle box through a connecting rod 45, a lever 32, and a rod 31 and the spare shuttle 21 goes into service. The shuttles in the magazine are retained by a plate 51 controlled by a roller 55, and the empty shuttle 20 is ejected by the stems 25 of an expulsion plate 24 striking fixed buffers 57. A second segment of the gear 36 then rotates the eccentric another half turn, thus returning the shuttle box to its normal position, where the next shuttle drops into the upper cell.
