Abstract
A smoke detector testing device includes a housing, an impeller rotatably mounted in the housing, and means for rotating the impeller. The housing has a port opening into the housing for receiving the unlit end of a cigarette and an elongated hollow tube extending from the housing for discharging smoke therefrom when the impeller is operated thereby to project smoke to a remote location adjacent a smoke detector mounted on the ceiling of a room or the like.
Claims5
A smoke detector tester comprising a housing, an impeller rotatably mounted in said housing, and means for rotating said impeller, said housing having a port opening formed therein for receiving an end of a burning object and an elongated hollow tube extending from the housing for discharging smoke therethrough from said object;
- said housing including a pair of separate impeller chambers formed therein with said impeller being mounted on one of said chambers, said means for rotating said impeller including a second impeller rotatably mounted in the other impeller chamber and drivingly engaged with the first mentioned impeller, said housing including an apertured mouthpiece, separate from said port opening and said hollow tube located in communication with said other chamber whereby a person may blow into the mouthpiece to rotate said second impeller and thereby drive said first impeller to draw smoke from the burning object through the port into said one chamber and out through said elongated hollow tube.
A smoke detector tester comprising, a housing having a gas chamber formed therein, a gas impeller rotatably mounted in said housing in said gas chamber, means for rotating said impeller, said housing having a first opening formed therein for receiving an end of a cigarette or the like and a second gas discharge opening therein, and an elongated gas discharge tube secured to said housing in communication with said gas discharge opening whereby, upon operation of said impeller by said rotating means, gas particles are drawn into said chamber from said cigarette and projected through said tube to a remote location;
- said housing including a second chamber separate from and coaxial with said gas chamber, said impeller having an elongated shaft extending from said gas chamber into said second chamber, said means for rotating said impeller comprising a second impeller in said second chamber secured to said shaft, said housing including an apertured mouthpiece formed thereon separate from said first opening and tube in communication with said second chamber whereby a person may blow into said mouthpiece to rotate the second impeller and drive the impeller in the gas chamber to draw smoke particles into the gas chamber and discharge them through said tube.
