A closed pressure container is provided and includes an upper valved outlet. An upstanding tube assembly including concentric inner and outer tubes stationarily supported relative to each other is disposed within the container and the upper end of the outer tube is sealingly supported about the outlet and extends downward toward the lower end of the container with the outer surfaces of the outer tubular member spaced inwardly from the inner surfaces of the container, thus providing three concentric pressure chambers within the container. The outer annular area within the pressure container includes a lower portion for receiving dry chemicals and and an upper portion for receiving compressed propellant gases. The innermost area comprises a secondary independent propellant gas storage chamber closed at its lower end by means of a selectively openable valve and the intermediate annular area defined between the inner and outer tubes defines a discharge passage upwardly through which dry chemicals may be propelled by the propellant gas upon opening of the valve at the outlet of the container. The valve at the outlet of the container includes a manual operator as well as a temperature responsive actuator. Also, a safety control is provided whereby the functional ability of the temperature responsive actuator is automatically registered by visual indicia in the event the temperature responsive actuator is rendered inoperative.

WILLMS CHARLES F |
A discharge valve for each of a plurality of manifold connected containers for fire extinguishing fluid, the discharge valve including a main valve pressure seated by fluid in the container to which it is attached and openable by pressure in the valve outlet from the manifold. This action is achieved by use of a double faced two diameter piston integral with the main valve member. A combination filling and pilot valve is included so that each container may be separately filled while connected to the manifold. The pilot valve may be actuated to discharge one container to provide manifold pressure for discharge of the remaining cylinders.

A sealed vessel, containing a fire extinguishant or explosive suppressant, has, clamped to the outside of a frangible wall portion of the vessel, a cap-shaped member supporting an explosive line charge arranged around part of a circle and held against the vessel. An electrically actuated detonator is also carried by the cap member for detonating the charge and opening the frangible opening to release the vessel contents into an exit pipe. A layer of explosive suppressant is carried by the cap member to overlie the explosive charge and to suppress the advance of its explosive along the exit pipe.

HANSEN A |
A safety valve for use in filling of fire extinguishers and the like is disclosed. There is provided the usual storage container for containing fire extinguishing chemicals under pressure and having a control head attached thereto at one end. The control head is provided with a pair of discharge passages in fluid flow communication with the interior of the container. A main valve seals one of the passages and a safety valve is provided to seal the other passage. Preferably, the two passages are continuous so that a stem of the main valve extends from the one passage into the other. The safety valve is acted upon by the fluid when the main valve is open. A compression spring is connected between the stem and the safety valve tending to close the latter when the former is open. When fluid pressure on the safety valve is greater than the pressure from the spring, the safety valve moves to vent fluid from the container to the atmosphere.

A fire extinguisher head assembly includes a core, a syphon tube seated in said core, a spring biasing a valve construction upwardly into engagement with a valve seat on a retaining bushing that is screwed into the core to clamp the syphon tube in place. An independent handle and valve-operating assembly may be attached to said retaining bushing with a quick-release coupling. Said operating assembly includes a body portion having a collar that fits about a retaining bushing, a handle means, an actuator pin connected therewith, a discharge rod extending through a vertical passage from the valve construction to a pivoted operating lever means whereby upon depression of the rod by the operating lever the valve is unseated and allows discharge of the receptacle contents through the vertical passageway and intersecting generally horizontal passageway. An alternate operating means includes a cam pivotable by a sliding trigger to depress the actuator pin.

THIS INVENTION RELATES TO A SPRING LOADED CAM LOCKED RELEASE MECHANISM USED FOR FIRE EXTINGUISHERS. THE MECHANISM COMPRISES A SPRING LOADED CAM PLATE HAVING AN ACTUATING BOLT FIXED THERETO AND ADAPTED TO UNSEAT A VALVE ON A FIRE EXTINGUISHER, A RELEASE BAR HAVING A STUD ON THE TOP THEREOF FOR ABUTMENT AND A PAIR OF SPACEDAPART INTEGRAL INCLINED SLOPE CAMS THEREBELOW UPON WHICH SLOPES SAID CAM PLATE RESTS WHEN IN COCKED POSITION, A GUIDE PLATE DISPOSED IN A CO-ACTING CHANNEL IN SAID CAM PLATE FOR HOLDING SAID CAM PLATE IN HORIZONTAL POSITION AT ALL TIMES DURING VERTICAL MOVEMENT THEREOF, AND A CABLE RETAINER BAR SECURED SWINGABLY TO A TENSIONED STEEL CABLE HAVING A FUSIBLE LINK AND ALSO SECURED LOOSELY TO A HAND PULL CABLE FOR VERTICAL MOVEMENT OF SAID CABLE RETAINER OVER SAID STUD OF SAID RELEASE WHEREBY MOVEMENT OF SAID CABLE RETAINER EFFECTS RELEASE OF SAID RELEASE BAR TO PERMIT SAID CAM PLATE TO MOVE DOWNWARDLY UNDER SPRING PRESSURE ON SAID CAM SLOPES THEREBY ALLOWING SAID ACTUATING BOLT TO STRIKE A RELEASE PIN TO UNSEAT THE VALVE ON A FIRE EXTINGUISHER.

PALMA JOSEPH S DE |
A portable automatic fire extinguisher having a tubular member mounted exteriorly of the extinguisher housing and containing a fluid that expands significantly in response to an abnormal ambient temperature condition. A bellows is surrounded by the fluid and is displaced during fluid expansion. A push rod is connected to the bellows at a first end of the rod while the opposite end mounts a valve. When the bellows is displaced, the push rod is similarly moved thus causing the valve to open and free a stored reagent for mixing with a second reagent which results in the formation of a fire-extinguishing liquid. A discharge tube is disposed in the extinguisher housing and has a nozzle end extending outwardly from the housing so that the extinguishing fluid can be discharged omnidirectionally.
