FIBE-EXTINGUISHER.

Specification of Letters Patent.

Application filed March 11, 1909. Serial No. 482,650.

To all whom it may concern:

Be it l-inown that I, Gnonon C. Maonm, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain Improvements in FireExtinguishers, otwhich the following is a specification.

The objects of this invention are to enable a fire extinguisher and its accessories to be more conveniently and compactly packed for shipment from the factory to the customer or user; to avoid the necessity of a number of small packages or parts to accompany the tank portion or fire extinguisher-proper; to utilize the interior space of the fire extinguisher for containii'lg such accessories; to prevent the interior parts of the lire extinguisherand said accessories from shaking or rattling around inside the tank during transportation; to save labor and expense in packing and shipping the fire extinguishers, and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawings, in. which like numerals of reference indicate corresponding parts in each of the several figures, .l igure l is a plan of a fire extinguisher embodying my improvements; Fig.

2 is a similar View with the screw cap or closure removed; Fig. 3 is a side view of the tire extinguisher partly in central section on line 3, 2:) Fig. 2, and Fig. l is a de tail cross section taken on line 4., 4; of Fig. 3.

In said drawings, 10 indicates the usual cylindrical tank of a hand lire extinguisher provided with a discharge pipe 11 and a handle I12 .t'or handling or supporting the extinguisher. Said tank 10 provides above its bottom 13 a chamber adapted to contain a solution of bi-carbonate of soda or the like, and access to which chamber is had through a bushing 14 inserted in the top of v the tank. This bushing is externally threadcd at its projecting portion to receive a screw cap or closure 15, and also has lugs 16 projecting radially inward and forming lips or stops for the flange 17 of the top ring 18 of a bottle cage. This acid bottle cage, for purposes of illustration, 1 have shown of substantially the construction shown in Patent No. 735,480, it having downwardly extending straps 19 crossing beneath the bottle 20, and its top ring 18 being split to allow spreading to remove the said bottleQt).

in carrying out my invention. a pasteboa'rd lube Ell is inserted through the top opening of the lire extinguisher tank, so that said tube stands at its lower end upon the bottom 13 of the tank and at its upper end lies within the bushing 14, or lugs 16 thereof. The proper amount of bi-carbonate of soda imcessary to charge the fire extinguisher is contained in a paper bag 32 adapted to enter the said pasteboard tube 21, and the mouth of said bag is tied with a cord 23 which at its other end is attached to the bottom of the acid bottle cage 2st, as at The bag is then dropped into the pastcboard tube 2.1 so that it rests upon the bottom thereof or upon the bottom of the tank )3, andthe acid bottle cage enters the top of the pasteboard tube 21. and engages at its top ring 18 the bushing l-land lugs 16 thereof, so that said acid bottle cage is supported as usual. There is sullicient length of the cord 23 between the bag and cage 24. to enable said bag to rest upon the bottom of the tube or be supported by the bottom l3 of the fire extii'iguisher tank.

The lead stopper 26 for the acid bottle 20 is put in the top of the bag 22 upon the bicarbonate of soda therein, as shown. The acid bottle 20 has been filled with the proper amount of acid, as usual and said acid is confined for shipment by the ordinary rubber stopper 27. The screw cap or closure 15 is then screwed firmly upon the top of the fire extinguisher tank, and the [ire extinguisher is ready for shipment from the factory.

It will be understood that the acid bottle cage 24- depending into the tube 21 holds said tube in central position of the fire ex tinguishcr tank, and said tube serves during shipment to retain the bag 21 against undue mm'ement or shaking around. When the fire extinguisher is to be charged by the purchaser, the acid bottle cage is first taken out, and by the string 23 the bag 22 is also withdrawn, the tube 21. serving as a guide for said bag. The tube 21 may then be removed, the bag 22 detached from the said bottle cage, the stopper 26 taken out of the bag, and the rest of its contents poured into the fire extinguisher tank and mixed .with water as' usual. The rubber stopper 2"?- is then removed from the acid bottle, the lead stopper 26 inserted as usual, and the .cage placed in the topof the fire extinguisher, asisordinarilydone. A

It will be understood that by my 1mproved construction, the fire extinguisher as sent out from the factory contains within itself, securely acked, everything necessary for charging t e extinguisher. There are therefore no outside accompanying packages to carry the different accessories, such as would not only add to the bulk of the packed fire extinguisher but also render said accessories liable to loss or breakage. By my-invention the said accessories are absolutely safe from damage or loss, are occupy-ing what would otherwise be waste space,

and can be packed without any special care or attention. I thus. save labor and expense not only in preparing fire extinguishers for shipment, but also in the actual shipplng of the same for transportation of them.

'It will be understood that the tube '21 may be of any suitable material or construction, and that its lower end may be either closed or open. Also the bag 22 may obviously be of any suitable material .or construction, or under some conditions dispensed with entirely andthe bi-carbonate of soda or other dry chemical retained in the lower end of the tube 21 by other means.

Having thus described the invention, What I claim is.

the lower part of said tube against distribution, and a cap or closure for said tank.

2. In a fire extinguisher, the combination of a tank having an opening at its top, a

tube in said tank supported by the bottom 7 of the tank an acid bottle cage supported on said tank at said opening its top and depending into the said tube and fitting the same, means in the lower part of said-tube.

for confining a dry chemical against distribution, and a cap or closure for said tank.

3. In a fire extinguisher, the combination of a tank having an opening at. its top, an acid bottle c'a'ge supported on saidtank at said opening and projecting into the inte-.

rior chamber thereof, a tube fitting upon said cage and extending beyond the .same 'into the interior chamber of the tank, means in the inner end portion of said tube beyond the, said cage for confining adry chemical against distributiom-and-a cap or closure for said opening of the tank.

4. In a fireiextmgulsher, the combination I of a tank having an opening at its top, an acid bottle cage removably supported on said tank at said opening and projecting into the interior chamber thereof, a tube fitting upon said cage and projecting therebeyond into the interior of the tank, a container adapted to confine a dry chemical arranged within said tube beyond the inner end of the cage, means connecting said container to said cage, and a cap or closure for said container.. g

5. In a fire extinguisher, the combination with a tank having an opening at its top, a

tube in said opening extending into the interior of the tank, a container in said tube adapted to confine a dry chemical, means attached to said container and accessible from the outside of the tank for sliding said container out, of said tube,-and a cap or closure for the tank.
