' To operate the fire alarm signaland photographic apparatus the handle 34- is turned 1n the direction of the arrow in Fig'. 3 until the gong 48 rings. Thereby the ratchet wheel 38 is turned one quarter of a revolution and makes electric contact4 with a quadrant of the Contact making ring 55. The electric contact is broken when the next electric'circuit breaker 56 is reached. By closing the electric circuit with the turning of the handle 34 the electric motor `118 1s ener ized and through its connections, the turnta le127 is turned one revolution, which swings thetubular arm 71. At the same time the housing 180 of the signal and photographic apparatus is revolved around the pole 68A and the lens 190 of the moving picture camera 215 is focused on the fire` alarm signalbox l25, and thereby any person in the vicinity of said box is photographed. armature'shaft y196 in the siren 195 is turned and an audible signal is produced. With the rotation of the shaft 196, and by means of the pulleys V202, 217 andthe belt 218, the moving picture camera 215 is operated.
