Carbon monoxide detector and deactivating mechanism
First Claim
1. A carbon monoxide detector assembly, including means defining a compartment, a first detecting means defining an electrical detector to detect a pre-determined amount of carbon monoxide in said compartment and respond thereto, a second detecting means defining an electro-mechanical detector to detect the same pre-determined amount of carbon monoxide in said same compartment and respond thereto, means defining an internal combustion engine source of carbon monoxide, signal means to signal the presence of a dangerous level of carbon monoxide concentration when detected by said first and second detecting means, a deactivating mechanism to discontinue operation of said internal combustion engine source of carbon monoxide upon receipt of a signal from said signal means that a dangerous level of carbon monoxide concentration is present, said deactivating mechanism being responsive to said signal means to cause operation of said internal combustion engine source of carbon monoxide to be discontinued, said deactivating mechanism including automatic reset positive interruption means to automatically restore conditions for operation of said internal combustion engine after interruption thereof by said signal from said signal means, positive indication means to indicate that said internal combustion engine has stopped operation, wherein said deactivating mechanism will not restore conditions for operation of said internal combustion engine until receipt of a positive indication from said positive indication means that said internal combustion engine has stopped operation.

Abstract
A carbon monoxide detector and deactivating mechanism to monitor the level of carbon monoxide concentration within the passenger compartment of a vehicle having an internal combustion engine, and to stop the operation of such internal combustion engine when the level of carbon monoxide concentration reaches a danger point for occupants of the passenger compartment. The detector includes plural detecting means to determine such dangerous concentration level, at least two of which detect carbon monoxide in the atmosphere by different methods and principles of operation. The detector is electrically connected to the vehicle'"'"'s electrical system and when the critical pre-determined level of carbon monoxide is reached, it triggers a vacuum switch to interrupt the ignition circuit of the vehicle for a long enough time to insure that the internal combustion engine has been stopped.
