Application filed Apr 1, 1903. Seriai No. 125,158.
To all whom it 'may concern:
Be it known that l, Devro lnwiN GenitorsON, s citizen of the United Ststes, .residing at New York, in the county of New York and State of New York, have invented ncrv and useful lm roveinents in llireEXtinguisliers, of which t c following is a specification,
My invention relates to lire extinguishers in which the liquid is discharged 'oy the efr.- pansive force ot gas.
One of the objects oi my invention is to provide e fire extinguisher that can be inode to release compressed carbonio acid or other gas in installments or continuously to suit the will of' the operator for the purpose oi cre' ating a, pressure which will rorce the vliquid from the extinguisher.
Another object of rny invention is to provide means for erecting s pressure within'the tenir at the 'saine instant that the discharge passage is opened; and to provide means for closing the discharge passage at the salue instant that the pressure is cut oil.
Another object is to ineke allowance for the contraction and expansion of the lid uid in the tank due to variations in the temperature;
Another object is to provide a device which permits of the use of non-freezing compounds in lire extinguishers.
@ther und further objects will appear from the following speciiicstion.
ln the drawings, Figure is a front elevation ofs re extinguisher embodying niy invention; Fig. 2 is s view partlyin section showing the extinguisher when not in use Fig. 3 is a view similar to Fig.` 2, showing the relative arrangement of the parts when the extinguisher is in use; Fig. L1 is a plan view of the ton; rig. 5 is an inside View of the top; and 1g. 6 is an elevation oi the cartridge end means foropening the discharge-valve he lower end o? the gescartridge showing the pin valve. l
Referring to the drawings, in which the reference characters refer'- to the some parts on all views-.i2J shell or tanl': 1 provided at its upper open end with en interrupted lug thread 2, is surmounted by e ilangcd hoort casting 3 edo-pted to las iirrnly 1out releasabiy secured thereon oy means lugs efu' on the heed-cesting 3. Blurred to their end depending thereiroin, is 5 provided at its lower end strainer 5. .dpproninietely 1 height of the discharge-pipe 5, is soldered or otherwise securely fastened thereto, a small bracket 7 provided with on upwardly projccting pin S to be hereinafter referred to. Surrounding the pin 8 and su ported by the bracket 7, is a resilient niernlier, preferably a spring 9, .having secured thereto et its upper end a washer 10 to be referred to hereafter.
Referring more especially to Figs. 2, 3 end 5, the heed-casting 3 will oe seen to be provided with a slotted spherical recess or depression 11 within which an oilset cani por tion 12 olf the vulve-key 13 is permitted to revolve to operate the cartridge 20 as explained hereafter. The valve-key 13 is provided with a passage 14v and rotatably mounted within a cylindrical protuberance 15 upon the headecssting. lt 1s provided at its outer end with a goose-neck 16 and a, lever 17 lieving attached thereto, a hose 1S. ln the outer end of the hose, is secured a nozzle 19 inode without a stop-cock to render it impossible to cut oli vthe out-How during the generation of' pressure within the tank. The steel cartridge 2O ior containing compressed carbonio acidor other gas is of a well known design und needs no detailed description. Within; its lower end is provided a spring retained vulve adapted to be forced open to permit the outilow of coniined gas when the eartridge is forced downwardly over the in 8. Tirepin valve is shown in detail in iig. 7. The cap 25 is screwed into the neck of the cartridge by Ineens oi the threads 2G, until l the ilange 27 abuts against/thc end of the cartridge. .The upper cud 2S of this plug acts as a volvo scart with which the inside valve 29l` engages, to control the flow in and out of the cartridge. The valve 2) is screw threaded at 3() upon spind e 31 which passes down into the neck oi the plug und is providedwith en eulorgedihead 32. Between the head 32 of the spindle and the shoulder 323 ot' the plug there is placed a s )irai spring 234 which keeps the vulve normally closed. when in posi tion within the touli, said cartridge is held against lateral displacement by the discharge pipe and the lugs 1121, upon tlic under side of the cover 2:1. The lugs 21 :ire limited in length o permit the cartridge to be inserted end with lmwn luy shifting its lower eud sid ciw row to the .uli'c-iicy lll, (Shown 1 Il), -lic einer end oi: the s prorielcd it. s larger hole 22 Vtridge down over t e pin S which opens the Q ete,
through which the liquid is permitted to lloW -when the extinguisher is in use, and a smaller hole `which registers with a corresponding vent-hole 24 when the valve-key is in its normally closed position. From ythe drawings, it Will be apparent that the larger hole 22 which communicateswith the discharge pipe 5 when the valve-key is in its il uid-discharge p0sition,is disconnected from said discharge pipe during the normally closed position of the valve-key.
The method of operating the extinguisher may nov,T be readily understood and is as follows: Allowing the hose to hang i'loivnivard with the valve-key in the position shou'n in Fig. 2, the spring 9 is compressed by pressing doivraupon the Washer l() When the cartridge may be easily slipped into position With the valve oi the cart ridge directly o the opening pin Upon releasing the spring 9, t. Washer 10 immediately snaps into position against the flange surrounding the cartridge valve. Upon Vfilling the tank 1with the lireeXtinguishing liquid, the apparatus is ready for use. By raising the lever l? (which constitutes the outer end ci the valve-korf), upwardly in either direction, the cani-movement of the oliset ortion lf2 forces the earvalve in the cartridge and allows the gas to escape therefrom. The pressure thus created in the tank, forces the liquid through discharge pipe 5 from whence it may be di rected in any desired direction by means oi the nozzle i9. gWhen the valvc-key-lever i7 reaches a horizontal position while moving upwardly, the vent-hole is closed while the larger hole 22 is being opened and b r the time the cartridge has been forced own- Wardly suiiiciently far to force itsvaive open, the hole 22 has ooened completely. lo cut olf the ilovl, the jlever i7 is returned to its lowered position whereupon the supply of carbonio acid gas is cut oil simultaneously with the cessation of the ilorv of the liquid.
It will be seen that the vent-hole 23 is adapted to relieve any residual pressure in the tank when the same isl no longer in use, While at the same time, a convenient means is provided for allowing for expansion and contraction in the liquid due to changes in temperature to which the tank may be exposed. I
Owing to the simple construction oi the head-casting and the means provided for rcleasably securing the same to the tank, a quarter turn is all that is needed to lock or unlock the head-casting. As shown in the drawings, the entire uuchanism of thc extinguisher is attached to the head-casting which permits the apparatus to be prepared for operation willi a minimum expenditure oi' Lime and effort. Further advantages will bi' apparent in the simple construction, ease ol' manipulation and the Creation. oi pressure ssi Within the tank only at the times When the liquid is being used.
Having thus described my invention, the following is what l claim and desire to secure by Letters Patent:-
