Abstract
650,234. Starting and stopping gear. VICKERS-ARMSTRONGS, Ltd. Oct. 13, 1948, No. 26673. [Class 80(ii)] [Also in Groups XXVI and XXXVII] Starting and stopping gear for a press is controlled by a lever 6 on a pivot 4, the outer end of the lever being connected to a treadle while its inner end carries a spring-pressed pawl 8 coacting with the inner end of a lever 5 on the same pivot 4, the outer end of the lever 5 being connected to the starting and stopping means, e.g. a clutch or electric switch or throttle valve and a brake. A second pawl 13 is mounted on a fixed pivot pivot 14, and a hand-lever 17, pivoted at 18 and carrying a pin 19 adapted to be engaged in any one of three holes 20, 20a, 20b, pivotally carries one end of a link 22, the other end 23 of which is controlled by cam means driven by the press. With the pin 19 engaged in hole 20, as in Fig. 1, depression of the treadle causes the inner end of lever 5 to be raised, by means of pawl 8, to a position in which it is held by the pawl 13, irrespective of whether the treadle is released or not. The machine is thus started and runs until the link 22 moves so that a part 22b depresses an arm 13a of pawl 13 (and also, if'treadle has not been released, an arm 8a of pawl 8) so as to release the lever 5, which returns to initial position, stopping the machine. With the pin 19 engaged in hole 20a, Fig. 5, a part 17a of the lever 17 engages a part 13b of the pawl 13 so as to displace the latter and render it incapable of holding the lever 5. The machine is started by depression of the treadle but may now be stopped at any time by release of the treadle, the machine being in any case finally stopped by the action of the link 22 in tripping the pawl 8. With the handle in the third position, in which the pin 19 is engaged in the hole 20b, the pawl 15 is again held inoperative but the link 22 is also displaced laterally so that it cannot contact the pawl 8, so that the machine continues to run so long as the treadle is depressed.
