Abstract

399,034. Burglar and like alarms. ADLER, H., 121, Mile End Road, London. Nov. 9, 1932, No. 31619. , [Class 118 (i).] An attachÚ case 8 is provided with an alarm buzzer 5 which is automatically sounded when the case is lifted and also when it is snatched from the owner's grasp. For this purpose two switches d, 12 are provided in an electric relay circuit b, the switch d projecting through the bottom 20 of the case and being closed by a spring when the case is lifted, while the switch 12 is normally kept open by the owner's grasp on the handle e of the case. Closing the relay circuit b attracts armature 2 and closes contacts 3, 4, thus completing the main circuit a which maintains the armature 2 in its attracted position so that the buzzer continues to sound after the circuit b is opened. By. connecting. the locks 7 in the circuits, the system is rendered inoperative when one or both of the locks is opened. The batteries 6 are housed in a compartment 17 accessible through a hinged flap 18.
