1. An alarm adapted to be associated with a removable fire extinguisher to indicate removal of the same, comprising:
- a bracket member having a flat base portion and upstanding wall portions normal thereto, said bracket member being adapted to be mounted relative to a fire extinguisher so that the flat base portion is positioned adjacent the base of the extinguisher;
a pivoted spring biased flange member having a flat plate and a trigger portion normal thereto mounted on the flat base portion of the bracket member, said flat plate of said flange member being positioned parallel to and adjacent the flat base portion of the bracket member when a fire extinguisher is so mounted that its base rests on the flat plate, said flat plate of the flange member being urged away from the flat base portion of the bracket member when the fire extinguisher is removed;
a support mounted on one of the wall portions of the bracket member; and
an alarm horn having a self-contained pressurized gas supply coupled thereto mounted in said support, said trigger portion of said flange member being aligned with and adapted to pivot against the gas supply with pivot of the spring biased flange member away from the flat base portion of the bracket member to release gas from the gas supply to sound the horn.

Abstract
This invention relates to a fire extinguisher alarm for use with a removable fire extinguisher. The alarm includes a support bracket mounted in an enclosure housing the fire extinguisher or in proximity with a mounted fire extinguisher. The support bracket has a pivoted plate adapted to engage the base of the mounted fire extinguisher. The plate includes a trigger arm, which when pivoted, engages a audible alarm formed by a pressurized gas can and horn, tilting the can relative to the horn to permit the release of gas under pressure to operate the horn.
