OF NEW YORK, AN. Y., A CORPORATION OF DELAWARE.-

Speciucation of Letters Patent. Patented June 2S, 1921.

. Application led January 27, 1919, Serial No. 273,412. Renewed November 18, 1920. Serial No. 425,032.

To all whom t may concern Be it known that L-"Gumo BLnNIo, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new an'd useful Improvements in Fire-Extinguishers, of which the following is a description, reference being had to the accompanying drawing/, forming a part hereof.

y invention relates to fire extinguishingv apparatus and has for its object to provide a simple, efiicient and inexpensive device for this purpose which will be always ready for use and can be set in operation instantly, requires no special skill to put in operation or to use and is adapted to be used with one hand. `A further object of the invention is to provide a device of this charac-l ter with the fewest possible number of arts, which will not get out of order and will, at all times be absolutely tight against leakage.

With these and other objects hereinafter explained in view my invention consists in the; construction and combination of parts hereinafter described and claimed.

Referring to the drawings Figure 1 'is' a vertical central sectional view of a device embodying my invention and Fig. 2 is a top plan view with the rod 18 and head 19 removed.

In the drawings v1 indicates the container here shown las formed of metal in the form of a cylindrical vessel with. fixed bottom 2.

At its upper end the contalner is provided f with a top 3 firmly secured to it and having a large central opening screw threaded at 4. This container may be provided with a handle 5 though for ordinary purposes it will be made of such size as to be readily grasped in the hand and no handle will be needed. This container is made sufficiently strong to withstand the pressure 4of gas as hereinafter vdescribed and may be made of heavy glass if preferred. Ifmade of metal it is preferably coated on the inside with shellac or Iother material which will protect the metal against any corrosive action of the liquid in the contalner.

A head 6 is constructed to fit the opening in the top in which it is adapted to be Se.-A

cured by screwthreads 7 tting the screwthreads 4. Thishead is arranged to carry all the operating parts of the extinguisher. It has on its up er side a central boss 8 whicli-is adaptedp to'lreceive a wrench by which the head may be screwed into placeor unscrewed, and has on its under side a lcentral boss 9 screwthreaded on its exterior at 10 to receive the upper end of a receptacle 11 adapted to hold a capsule 12 as herein? after described. Thehead 6 also has at one lside of the bosses 8 and 9 a smallopening in terminating inl a pointed end 20. On thev rod 18 below the boss 9 is a washer 21 of cork or leather which is held in place by a nut 22 which is screwthreaded to fit the screwthreads of the rod.

Between the head 19 of rod 18 and the to of the boss 8 is arranged a Spring 23 whic acts to force the rod normally upward and .to hold it in such position in order to keep the pointed end ofthe rod away from the capsule 12. The' extent to which the rod may be forced outward by the spring is determined by the position of the nutl 22 and the washer 21 and by screwing the nut up or down on the rod the position in which the Y point o'f the rod is held may be regulated.

The lower end of the boss 9 is faced olf so that the washer 2 1 will fit closely against it and make with it a liquid and gastight joint. The receptacle 11 for the capsule 12 is provided in its sides with openings 24 and 25, the upper openings 24 being arranged substantially in line with the upper end of the capsule 12 and the openings being one opposite the other so that by looking through .them the position of the point 20 relative to the upper end of the capsule may be seen and such adjustment made as may be desirable.`

The capsule 12 is of the usual construction of capsules for holding liquefied or highly compressed carbonic acid gas or other gas or air,l the top of the capsule being adapted, as -is usual, to be pierced or broken by the point 20 to release the gas.

In use thecontainer 1 is filled to about` the line 26 with the lire extlnguishing 2. id which iS Preferably. `aie-hieraii'yiim li 2H013) which I have found to. be superior .for fire extinguishing pur oses to the carbon tetrachlorid common y used `in hand fire, extinguishers, for the reason among others that it does not attack metal and is a more eii'ective non-conductor of electricity, a-fact which is of importance if a fire in which electric light wires o r other wires carrying high currents are involved the stream of liquid from a fire extinguisher "sometimes Aforming apath for the current to the injury or even'death of the erson using the extinguisher. `Trichlorethy ene is also somewhat less expensive than carbon "tetrachlorid which,however, may be usedin my device above described particularly if the interior of the container l, if of metal, is coated with'shellacas above suggested or with a solutionvof glue to which a small v`amount of glucose 'or glycerin has been add- `v`-ed,y or with pyroxylin or any other coating "which Will not beaected by carbon tetra- A-f"chlorid.

. scribed. to the line 26, a filled capsule 12 is placed in the receptacle 11 and the receptacle l-fWhen the container has been filled aside'- 5 is-screwed into place on the boss 9, the rod 18 being previously adjusted by screwing the nut 22 up or down as may be necessary. The

i head-6 carrying the capsule in the receptacle 11 andthe pipe 14 is 'then inserted in the opening in the top 3 and screwed to place gy means of a wrench applied tothe boss 8.

he extinguisher may then be. put in its rack or other place close at hand for use if needed. When needed to extinguish a fire a blow of the hand on the head 19 drives the pointed end 20 of rod 18 downward against theresistance of sprin 23 piercing the softend of the capsule. T e spring' at once act-s to Withdraw the point 20 so as to permit free escape of the gas which flows into the Aspace above the liquid creating a .high' pressure. The valve 16 may be opened either before or after the capsule is pierced. When the valve is opened the pressure of thegas drives the llquid in the container up through the `plipe 14 Vand out through the nozzle15 whi y :made'as show n with an interior taper so that thev liquid dischar d through 1t will be vsprayed instead e vvo being discharged' in a solid stream.

The nozzle 15 arranged as shown at a angle pointing slightly upwardso that when the container is inclined so as to direct the streamfrom the nozzle horizontally or down ward, the last of the liquidv will be brou ht directly-under the end of pipe 14 so t at practically all of it will be forced out before the gas can reach the end of the pipe.

The container 1 may be made yof any size desired but as above pointed out is particularlyuseful where made of such size that Vit may be graspedv in one hand and the stream of li uid thus directed by lone hand against the re leaving the other hand of the user free to pull or ush inflammable or other articles away. y reason `of this adaptability for one hand use without need for use of thev other hand except for an instant to drive the head 19 down, the device is particularly useful on aeroplanes as wellv as for vhousehold and other general use.

All of the operating parts .being carried by the head 6 can be readily gotten atifor suchV attentions as theymay need at any time. The washer 21 -being held against the 4face of the bossv 9 by the spring prevents any evaporation when the charged device is not in use and prevents any escape of gas around the rod 18 thus insuring that the/full force of the gas will be utilized to force the fire extin uishing liquid out.

n case a first blowon the head 19 should not fracture the end of the capsule a second blown'iay be struck on it thus insuring a full npening of the capsule Which is not always secured where a screw rod yis used. The washer 21 should not be of rubber, particularly if carbon tetrachlorid is used in the device because of the solvent action of It `is pref,-

n testimony whereof I aiix my signature-A this 25th day 'of January, i919. A l suino BLENio.
