Alarm light

Claim 1

An alarm light comprising a lighting means, an alarm means, and an actuator therefor, all substantially within a case, said lighting means comprising a light bulb in electrical contact with at least one battery, said alarm means comprising a tank which contains a source of pressurized gas, said tank including an outlet for the gas and a valve actuated by movement of the outlet to open the valve and release the pressurized gas from said tank through its outlet, said actuator being adjacent said tank and said bulb, and comprising a passage in communication with the tank outlet and leading from the outlet to a chamber releasably sealed by a disc in said actuator so that when the valve is open the gas flows through the outlet and said passage and into said chamber causing said disc to vibrate and emit a piercing alarm sound as the gas flows thereover, and a switch for said light bulb comprising a conductor in electrical contact with one terminal of said battery and extending to a contact point adjacent said bulb, said point being normally biased away from said bulb and adapted to be urged into contact therewith for completing an electrical circuit and lighting said bulb, at least a portion of said actuator being moveable between a first position in which said contact point is moved by a knob on said actuator into circuit-completing contact with said bulb, a second position in which the tank outlet is moved by said actuator to open the valve, and a neutral position.
