Abstract

1413213 Alarm clocks LOUIS SCHWAB SA I Oct 1973 [2 Oct 1972] 45718/73 Heading G3T [Also in Division H1] In an alarm clock having an electric alarm e.g. a bell 26, a wheel 1 is loosely mounted on minute wheel arbor 2 and is displaced axially when a lug 8 on hour wheel 6 enters an aperture 9 in alarm wheel 7 so that Breguet gears 4, 5 engage and the arbor 2 then drives the wheel 1 and thus a toothed sector member 11 carrying a contact member 12 which bridges fixed contact studs 15a-c to energize the bell. As shown the contact member 12 carries two brushes 13, 14 and gives a short ring after an initial delay, two minutes silence, and then a final, longer ring. A lever 17 pivoted at 18 is coupled to the sector 11 by a pin and slot 22, 23. Depression of a push-button (not shown) moves the lever in the direction of arrow B and advances the sector 11 in direction D, with slipping of the Breguet gears, to terminate the alarm. As the lug 8 rides up out of the aperture 9, the wheels 1 and 6 are returned axially against the pressure of a resilient fork 10 and a spring 19 returns the lever 17 and sector 11 to the initial position shown in Fig.2. The fixed contacts form part of a conductor 15 printed on substrate 15d and the moving contacts are protected by a plastics part 12a.
