UNITED STATES CLAUDE TESTE, JR, OF LYON, FRANCE.
FIRE-EXTINGUISHING DEVICE.
Specification of Letters Patent.
Patented May 24, 1921.
Application filed January '7, 1918. Serial No. 210,675.
I '0 all 20 1mm it may concern Be it known that l, Cannon Tns'rn, Junior, a citizen oi. the French Republic, residing at Lyon, in France, have invented certain new and useful Improvements in Fire-Extinguishing Devices, of which the following is a specification.
This invention relates to improvements in fire extinguishing devices.
Fire extinguishers generally consist of a receptacle containing liquid of appropriate composition which is projected by means of a pump placed inside or outside the receptacle and which is worked by hand, or by means of gases produced at the moment by various combinations.
These devices all offer some drawbacks; those with pumps are complicated, costly and necessitate a fatiguing and troublesome working for the expulsion of the liquid. The others are uncertain in working and being made of glass are liable to be inadvertently broken during transport or various manipulations, or owing to accidents, shocks, etc.
The subject of the invention is an extinguisher of great simplicity having an as sured working whatever manipulations or shocks it may be subjected to.
Its receptacle incloses the extinguishing liquid and the gas under pressure required for its total expulsion at the moment of use, which is effected by the simple opening of a valve arranged for that purpose.
The annexed drawing illustrates as an ex ample of realization of the invention a small portable apparatus: Figure l is a section of the head of the extinguisher, the valve being shown closed. Fig. 2 is a section showing the valve open. Fig. 3 is a section and Fig. l an elevation showing a modified form of valve.
The device comprises a cast cylindrical head Q, Figs. 1 and 2, the base of which is so shaped as to fit perfectly and conveniently on the neck r of the receptacle to which it is autogenously soldered. This head has a lateral pipe 8, the threaded end oi? which is closed with a screw-stopper s after introduction of the compressed air and also serves to receive the pipe for the intro duction of the compressed air.
The said head 1 is provided throughout its length with a bore having two diameters, connected by a conic part forming the seat 7' of a plug valve t, which is screwed into the hole of large diameter threaded for this purpose. This plug-valve t is also provided with a bore having two diameters connected by a conic seat a of a needle-valve screwed into the hole of large diameter and having a hand wheel w for its operation. The valve 2? ends in a six sided head t and it has at a given place of its length a circular recess w communicating with the bore by means of transverse conduits g].
For filling of the receptacle with the ex tinguishing liquid the valve 6 is unscrewed with a nut wrench and completely removed together with the needle-valve r, and the liquid is poured in. The filling being effected, the valve 2? is screwed in again care being taken to force it on its seat 7, then the needle valve 1) is put into the position of Fig. 2. If at this moment the tube conducts ing compressed air is screwed on the pipe 8 and the air admitted, it will enter above the liquid by passing through the neck m and the conduits 3 When the charge of compressed air has attained the desired pressure the air aomission cock is closed, then the needle valve o is strongly screwed on its seat i all communication of the charge of compressed air with the outside thus being interrupted.
To use the extinguisher it is suflicient to operate the wheel to in order to sufficiently unscrew the needle valve 4) and uncover the conduits ;z The extinguishing liquid will hen escape under the effect of the air pressure through the pipe 4:, from which care will have been taken to previously remove the stopper s lVhen the needle-valve '0 is of one piece the closing of the same on its seat takes place by screwing it firmly on the seat; thereby insuring an absolutely perfect closing but on the other hand the opening of the needlevalve requires considerable effort, which is an inconvenience. The latter is obviated by the construction of the needle-valve in two parts, as shown by Figs. 3 and 4E. The rod o is provided with an axial blind hole 0 and with a transverse hole d cutting through the periphery of the hole 0 as shown in Fig. 6. The conic point .2 comprises a cylindrical tail-piece a having the diameter and length of the hole 0 which serves as a casing therefor, and this tailpiece has an annular recess 6 coinciding with the transverse hole al when the said tail-piece a is in place. In this position a pin 6 is inserted into the hole (Z for the purpose of keeping the piece 2 in place.
It can be understood that this construction allows the piece 2 and the rod 4) to turn on their axes but without being able to separate from each other, hence when the needle-valve is screwed down the piece 2 stops turning when it is applied on its seat, but the rod e continues its rotation while effecting a progressive pressure on the piecev z to apply it firmly on its seat u.
The opening of the needle-valve is thus facilitated'and only requires a slight effort.
The construction could be reversed without inconvenience, that is to say, the male part would he the rod '0 and the point would be-arranged to contain it.
What claim as my invention and desire to secure by Letters Patentof the United States is 1. A fire extinguisher comprising receptacle having a head provided with a bore of two diameters, a screw plug valve in said head having an axial bore of two diameters, a screw needle valve arranged in the larger bore in the plug valve, and a lateral duct in the head through which the compressed air is admitted and the extinguishing liquid is expelled when the apparatus isin use, the screw plug valve being provided with lateral conduits communicating with said duct.
'2. A fire extinguisher as in claim 1 wherein the screw needle valve comprises a point adapted to rotate independently of the main rod of the valve.
In witness whereof I have signed this specification in the presence of two witnesses.
CLAUDE TESTE, JUNIOR.
