This automatic apparatus is for use by cigarette smokers who may be in danger of going to sleep with a lighted cigarette near at hand, to possibly cause fire and both personal and property damage. This apparatus is for use with an ashtray, and there is a socket in the top wall for receiving a cigarette lighter for storage therein. The apparatus includes an electric switch associated with the socket for detecting the presence of the lighter therein. In series with this switch is an ON delay timer that is in series with an audible alarm device. Also associated with the switch is a spring-biased plunger with a feeler pin that is capable of engaging the lighter. When the lighter is removed so that the user may light his cigarette, the plunger is allowed to move to close the switch thereby energizing the ON delay timer for a given timed cycle. A cigarette crusher is mounted adjacent the front of the apparatus. A linkage mechanism joins the cigarette crusher to the spring-biased plunger, for deactivating the alarm cycle when the cigarette is extinguished. If the cigarette is not extinguished, the alarm will sound.
