Abstract

250,934. Soc. Anon. G. Bassetti, (Assignees of Bassetti, F., and Formento, C.). April 15, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Weft-replenishing mechanism; shuttles, positioning for weft-replenishing; lays; beat-up motions; shuttle-boxes.-In looms provided with automatic spool-changing mechanism, the shuttlebox 4, Fig. 2, at the spool-changing end of the lay or both shuttle-boxes are stationary and are separated from the oscillating part 3 of the lay. Upon indication for weft-replenishment, a pin 22 is moved by link and lever devices from the weftfeeler into engagement with a groove 12 in a clutch member 11 splined on a rotating shaft 10. A cam on the clutch member 13 is thereby caused to operate the transferrer which is provided with a give-way device which operates when undue resistance is encountered. The weft ends from the cops in the magazine 26 are secured to holding means on a belt 32. The shuttle is positioned in the shuttle-box by cam-operated link and lever devices 37, Fig. 4. In order to prevent damage to the shuttle-box due to an improperly positioned shuttle, a portion 19 of the front of the shuttle-box is hinged and controlled by a spring. The movable portion 3, Fig. 3, of the lay is mounted on swords 1 linked to levers 2 and is operated by cams 5, 6 engaging bowls 7, 8 on the swords and levers 1, 2, the cams being designed to cause the lay to dwell while the shuttle is in the shuttle-box.
