CHEMICAL FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters :Patent No. 623,851, dated April 25, 1899.

Application filed May 4, 1898. Serial No. 679,688. (No model.)

To @ZZ whom t may concern.-

Be itknown that we,'ABRAM H. VAN HIPER and PATRICK F. GUTHRIE, of Nutley, in the county ot Essex and State of New Jersey, have invented a new and Improved Chemical Fire- Extinguisher, of which the following is a full, clear, and exact description.

This invention relates to improvements in apparatus for extinguishing fires; and the object is to provide an apparatus for this purpose having a permanent connection with a Waterdistributingpipe and to which new chemicals may be easily supplied as required.

7e will describe a fire-extinguisher embodying our invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of a fire-extinguisher embodying Vour invention and showing it as connected to a distributing-pipe arranged in a building. Fig. 2 is an elevation showing a modification. Fig.v 3 is a section on the line 3 8 of Fig. 1. Fig. L.tis aperspective view of a chemical cartridge employed, and Fig. 5 is a section on the line 5 5 of Fig. el.

Referring first to the example of our improvement shown in Fig. 1, 1 designates'a cylinder having a suitable closure 2 at its top and also having a valve-controlled pipe connection 3 with a watendistributing pipe et, designed to extend upward through a building, so that one of the tire-extinguishers may be connected to the pipe at each iioor. The lower end of the cylinder 1 has a nipple 4;, to which a hose 5 is attached.

Arranged within the cylinder 1 is a cartridge for holding a suitable chemical, consisting of a shell G, having perforations through its top and bottom and also through its side wall. The perforations through the bottom will be somewhat smaller than the perforations through -the top, so as to regulate the proper saturation of the water. This chemical may consist of four parts chlorid of ammonia to one part chlorid of soda. The cartridge or shell is made tapering, the larger diameter being at the top, and the diameter at the top is somewhat larger than the opening in a centering device 7, placed in the cylinder 1. One object in so constructing the shell is to prevent its being placed in the cylinder wrong end up. Another object in tapering the shell is to allow heavy solutions to discharge at the sides.

" In Fig. 2 we have shown two cylinders S and 9, and we have shown the covers 10 as secured in place by bails 11, so that said covers may be quickly removed when it is desired to put in a new charge of chemical, which it is to be understood is the same as in the example first described. These cylinders 8 and Qhave connection with a distributing pipe 12 through branch pipes 13 and 14, each of which is provided with avalve. This distributing -pipe 12 is mounted on suitable standards 15 and is designed to be connected at one end with a hydrant and at the other end with a hose 16. respectively, have

pipe connections

17 and 18 with a discharge-pipe 19, to which a hose 2O is attached, and forward of the branch connection with the pipe 12 the said pipe 12 is provided with a cut-ott valve'21.

In the operation of the first example of our improvement after opening the valve in the pipe 13 the water will pass int-o the cylinder and through the chemical in the shell or cartridge G, and this water charged with the chemical is to be discharged through the hose 5.

In the example shown in Fig. 2 it is designed When the chemical is used for extinguishing a fire that the amount contained in one cylinder shall be first used, and then the amount contained in the other cylinder shall be used. In other words, on closing the valve 21 and the valve in the pipe 14 and opening thevalve in the pipe 18 the water from the hydrant will pass into the cylinder S and through the chemical therein and will discharge through the pipe 19 and the hose. The check-valve in the pipe 18 will prevent the entrance of water to the cylinder 9. After all the chemical in the cylinder S shall have been used up the valve in the pipe 14 is to be opened and the valve in the pipe 13 closed,

The cylinders 8 and 9,

IOO

and then the water from the hydrant will pass through the cylinder 9 andthe chemical therein. AWhen water is to be used direct from the hydrant and discharged upon a fire, the valve 2l is to be opened and the valves in the pipes 13 and li closed. It is obvious, however, that both the chemical apparatus and the stream through the main hose 1G may be used at the same lime-for instance, for flooding a building and for discharging the chemical upon some portion of the ame.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. Xfire-extinguishingapparatus,co1npris iuga cylinder adapted for connection with a water-supply, a shell removably placed in said cylinder, the said shell beingr tapered throughout its entire length and provided with perforations in its sides and perforatious in its top and bottom, thebottom perforations heilig smaller than those at the top, whereby ihe water flowing through the shell will be regulated or retarded, means for centering said shell in the cylinder, and a removable cap for the cylinder, substantially as specified.

2. In a tire-extinguishing apparatus, the combination with a Water-supply pipe adapted for connection with a hydrant and also for connection with a hose, of a battery of cylinders, each cylinder having connection with said supply-pipe, the said connections being each provided with a valve, a valve in the supply-pipe, a discharge-pipe for the cylinders, apipe leading from each cylinder into said discharge-pipe, and an automatic valve in each of said connecting-pipes, the said supply-pipe and discharge-pipes being independent one from the other, whereby by hose connections, water may be discharged fromv both simultaneously in different directions, substantially as specified.
