Abstract

906,872. Clocks. MANUFACTURE D'HORLOGERIE FREY & CO. S.A. March 25, 1959, No. 10394/59. Class 139. [Also in Group XL (c)] An alarm clock radio comprises, in combination, a clock 1, Fig. 4, an alarm unit and a radio unit. The alarm unit includes a control switch 2, operated at a pre-set time to start an electronic oscillator 7 connected to an amplifier 69 to which is also connected a radio receiver 60, 61. The output of the amplifier 69 includes a loudspeaker 16. The oscillator may include a multivibrator which by actuation of a switch can be operated to provide a discontinuous signal to the amplifier which is provided with a volume control potentiometer. A six push-button switch arrangement is provided so that the radio can be operated on medium or long wave bands, the oscillator can be operated at either of two frequencies and the oscillator and/or the radio can be switched on by the alarm unit. One of the push-buttons, when depressed, switches off the oscillator and the radio.
