CHEMICAL FIRE-EXTINGUISHER.
SPECIFICATION forming part of Letters Patent No. 625,618, dated May 23, 1899. Application filed May 4,1s9s. Serial No. 679,689. (No model.)
To (tZZ whom it may concern:
Be it known that we, ,ABRAM I-I. VAN RIPER and PATRICK F. GUTHRIE, of Nutley, in the county of 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 of this character that may be easily transported from place to place and having a simple means for recharging the main chemical-holding cylinder after its original contents shall have'been discharged.
We 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 sectional elevation of'a fire-' extinguishing apparatus embodying our invention. Fig. 2 is a sectional elevation showing a chemicalcartridge employed and its arrangement with a hopper. Fig. 3 is a perspective view of said cartridge, and Fig. 4 is a section on the line 4 4 of Fig. 3.
Referring to the drawings, 1 designates the main cylinder, designed to contain a fire-extinguishing solution-such, for instance, as chlorid of ammonia and chlorid of soda and water. We find it best to employ four parts of chlorid ofammonia to one part of soda. Arranged on the cylinder 1 is a cylinder 2 for containing a compressed gas. This cylinder 2 has communication with the cylinder 1 through a pipe 3, provided with a regulating- Valve 4 and a cut-off valve 5. Arranged within the cylinder 1 and extended from the lower portion thereof through the end is a discharge-pipe 6, to which a hose may be attached. On the cylinder are a water-gage 7, a pressure-gage 8, and a safety-valve 9. An auxiliary cylinder 10 has a pipe connection 11 with the cylinder 1, and in this pipe is arranged a check-valve 12. Movable in the cylinder 10 is a plunger 13, having a screw-threaded stem 14 extended out-i ward through the rear end of the cylinder 10 and passing through a tapped hub 15 of a wheel 16, arranged between bars 17 and 18.
ward and the upper end being larger than the opening through which the cartridgeis passed. This tapering of the cartridge or shell will prevent its being inserted wrong end up.
The whole apparatus may be mounted on a suitable carriage, as indicated in Fig. 1.
While we show and describe herein a particular form of cartridge which we prefer to employ with the apparatus, it is to be understood that it is not specifically claimed herein, as it forms the subject-matter of another application filed by us under date of May 4, 1898, Serial No. 679,688.
In operation upon arriving at a fire the cylinder 1, which has previously been charged with the chemical solution, .is charged with gas from the cylinder 2. sure may be ascertained by the pressure-gage 8. This pressure will cause the liquid to discharge through a hose attached to the pipe 6. WVhile the contents are discharging from the cylinder 1,water may be poured into the hopper 19, and this water, running through the chemical in the cartridge or shell 22,Will absorb and carry with it certain portions of the chemical into the cylinder 10. Then by operating the plunger 13 and as the valve 12 automatically opens this new supply of liquid may be forced into the cylinder 1, and the apparatus is again in operating condition.
Having thus described our invention, we claim as new and desire to secure by Letters Patent--- 1. Afire-extinguishing apparatus, compris- The desired presing a main cylinder, a gas-pressure cylinder having connection therewith, an auxiliary cylinder having a pipe connection with the main cylinder, a plunger for operating in the auxiliary cylinder, a hopper having, connection with the auxiliary cylinder, and a chemical-containing cartridgein said hopper, substantially as specified.
2. Afire-extinguishing apparatus, comprising a main cylinder, a gas-pressure cylinder having connection therewith, an auxiliary cylinder, a pipe leading from the auxiliary
