Abstract: 609,312. Alarm mechanisms. LE ROUX, B. L. J. F. Aug. 1, 1945, No. 19835. Convention date, July 1, 1944. [Class 139] [Also in Group XXXVIII] A device for giving audible warning of the lapse of one or more predetermined intervals of time comprises a hand driven by clockwork over a dial until it passes over one or more movable studs, when the hand is forced outwards to release a clockwork bell-alarm. Movable studs 7, Figs. 1, 2, are placed in a slot 5 opposite appropriate graduations on a dial 4. To start the device a hand 43 is turned counterclockwise, until it is at zero on the scale 4, in order to wind up the main clockwork 3 and by means of gearing 28, 29 and friction cheeks 32 wind an alarm spring 31. When the hand 43 rides over any stud 7 it is forced outward from the dial 4, carrying with it pinions 17, 24, 25. The square-toothed pinion 25 is thus released from a fixed pin 26 and allows pinion 24 to be driven by the alarm spring 31 via gear 37 and thus cause ratchet wheel 17 to operate the hammer 14 of the alarm bell 13. When the hand 43 has left a stud 7, a retracting spring 44 forces the square-toothed pinion 25 against the pin 26 again and so locks the alarm mechanism. The main clockwork 3 drives the hand 43 for one complete revolution only.
