FIRE EXTINGUISHERy Filed Feb. 28,' 195o 2 sheets-sheet v2 Tiq. 57 2 Tg5 I N VEN TOR.

A TTORNE Y` Patented Nov. 21, 1950 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to a re extinguisher of the sealed pressure type; that is, one in which the extinguishing iluid is kept in the extinguisher under pressure until the time for use.

It is an object of this invention to provide an extinguisher of the type described which will hold the pressure within the container for a long period of time without substantial loss and which can be readily opened in time of need to permit the material to be discharged by the pressure.

It is a further object to provide an extinguisher of the type described, in which the valve mechanism will be held in the closed position by the combined action of the spring and of the gas itself and yet in which the closing elements may be caused to engage still more tightly by a simple locking arrangement to insure the maintenance of the pressure.

It is a further object to provide an extinguisher having an operating handle in convenient relation to a carrying handle, and having a locking mechanism convenient of access to the same hand, which can be made to lock the operating handle and which when in locking position will hold the valve mechanism tightly closed.

The invention accordingly comprises a device possessing the features, properties and the relation of elements which will be exemplified in the device hereinafter described and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

Fig. l is a central vertical section on the line of Fig. 4 with the valve closed and locked;

Fig. 2 is a fragmentary similar view with the valve open;

Fig. 3 is a side elevation partly in section of the upper end of the device;

Fig. 4 is a top plan View partly broken away;

Fig. 5 is a section on the line 5-5 of Fig. 1; and

Fig. 6 is a section on the line I--G of Fig. 1.

In the drawings, the numeral I0 is a container which may be made of spun brass, or as shown, it may comprise an upper shell I closed at the bottom by a base |2. The upper end is provided with a nipple I3 to receive the body |4 of the valve mechanism.

The body I4 has a central bore I5 having a rim I1 to form a valve seat. The smaller section I8 of the bore |5 serves as a discharge channel for the fluid, communicating with a lateral opening |9 communicating with a nozzle 20.

A valve stem 2|' in bore I8 carries a valve 22 having an upper flat surface of a resilient compound 23 impervious to the iiuid used, such for example as neoprene. The stem slides vertically in a packing 24 i` the bore, and it screws into a nut 25 which slides in a cylinder 26 concentric with the bore I5. A spring 2'I is confined between the nut 25 and a washer 28 resting on a shoulder 29 in the body I4. The lock nut 30 holds nut 25 in any adjusted position.

An opening handle 3| pivoted at 32 has a hole 33 surrounding the valve stem and is in a position to engage nut 30 when the handle 3| is depressed, as shown in Fig. 2, to force valve 22 away from valve seat I1,

The valve stem carries at its outer end a nut 35 and a flat locking nut 36 in position to be engaged by the handle 3| to pull the valve 22 against its seat I'I, when the handle is forced outwardly.

A locking lever 3l is pivoted to the body I4 and extends upwardly through an opening 38 in lever 3|. This lever has a cam projection 39 shaped and positioned so that, when handle 3| is raised, the projection may be forced beneath the handle, as shown in Fig. 1, to force the handle upwardly enough to cause rm engagement between the valve 22 and the seat I1.

A carrying handle 40 is pivoted at 4I so that it may be folded down against the container if desired or raised to horizontal position for carrying purposes. It is then in cooperative position with the handle 3|.

A nipple 42 ts into the bottom of bore I5 and carries a flexible tube 43 carrying a weighted end 44, so that it will always lie at the bottom of the container even though the container be tilted in use.

The container is provided with a side filling opening comprising a nipple 45 brazed into the side of the top of the container, carrying a tube 46 extending down into the container below the normal liquid level. This nipple is closed by a plug 41 tting against a neoprene valve seat 48.

The availability of this extinguisher in time of emergency depends upon the pressure maintained within it. There is thus provided a pressure gauge 50 fitting into the side of the body I4 and communicating with the interior through a channel 5|.

The locking lever 31 may be provided with a hole 53 through which the sealing wire 54 may be carried extending over any convenient portion of the apparatus, as for example, as shown in Figs. 3 and 4. This wire can be fastened with a seal 55.

Since certain changes may be made in carrying out the above process without departing from the scope of the invention, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.
