Abstract
1393826 Time switches; retarding action of switches TAMURA ELECTRIC WORKS Ltd 1 June 1973 [2 June 1972] 26264/73 Heading H1N [Also in Division G3] A repeating alarm device, for mounting on the frame 1 of a clock or radio receiver to provide repeating actuation of a buzzer or radio 17 energized from a source 18 over timer contacts 16, comprises a first gear 3 secured on a timedriven shaft 2, a second gear 4 loosely journalled on said shaft 2, a pivoted lever 7 carrying a pinion 10 for engaging the first and second gears 3, 4, a heart-shaped cam 5 secured to one side of said second gear 4, and a contact-actuating cam 6 also on said second gear 4 to close contacts 13, 14, when said second gear 4 is rotated to a predetermined position, the electric alarm means 17 being connected in series with said contacts 13, 14, and means 19 for rotating said lever 7 to disengage said pinion 10 from said gears 3, 4 and to engage said heart-shaped cam 5, thereby to return said second gear 4 to a position wherein cam 6 opens the contacts 13, 14. The pinion 10 normally runs in a toothless portion 4a of gear 4 and cam 6 holds contacts 13, 14 closed. After depression and release of pushrod 19 the pinion 10 meshes with gears 3, 4 until cam 6 again closes the contacts 13, 14, the pinion 10 again runs in the toothless portion 4a and the alarm sounds.
