Abstract: A self-contained fire protection system for an engine compartment and the like includes a gas cylinder or bottle having an outlet and a manifold secured to the cylinder. The manifold defines a through passage. Secured to the manifold is a thermally responsive actuator. The actuator includes a cap which is released in a fire condition permitting the contents of the cylinder to be discharged. A pressure switch having a pressure sensing port is mounted on the manifold. A switch activation accelerator includes an elongated stand pipe or tube extending from the pressure sensing port. The tube moves the effective position of the sensing port to an ambient pressure location.

Abstract: A mounting assembly for fire extinguishers which includes a bracket shaped to define a substantially V-shaped trough. A flexible strap is adapted to be wrapped tautly about the fire extinguisher and thereby hold it tightly in the bracket's trough. The strap includes a bail which cooperates with a pivotally mounted latch member for locking the strap against the extinguisher. The strap also includes an aperture which is adapted to be interlockingly attached to a hook structure provided on the bracket. This arrangement permits the strap to be quickly and easily removed from or attached to the bracket without the use of tools. Due to the bracket's substantially two-point engagement with the extinguisher, and the easy release and attachment of the flexible strap, the mounting assembly may be easily adapted to hold fire extinguishers of various sizes by the easily performed exchange of the flexible strap.
