FIRE EXTINGUISHER.

Application filed March 29, 1923. Serial No. 628,489.

Thisinvention relates to fire extinguishing and preventing means and more particularly to a tank of fire extinguishing fluid placed to the, immediate rear of the engine of aircraft.

I have shown a similar bulkhead in my copending application Sen #587,832, filed September 12, 1922,. now Patent 1,514,4 28,

of which this application covers. a modlfi cation.

It is the object of this invention to provide means that will tend to prevent conflagrations in the event-0f a head-on, crash of aircraft. In this connection it is contemplated that should fire ensue from such a crash, the tank containing the extinguishing fluid will burst, due to its low factor of safety, andwill envelope the structure for- 'Ward of the tank with a blanket of extinguishing fluid such ascarbon tetrachloride.

Further objects will become apparent as i the description of the drawing proceeds and from the claims.

In the drawing:- Fig. 1 is a side sectional'elevation of the forward part of an airplane showing the tank. installation.

Fig. 2 isa top plan view of the same. Referring to the drawing in the forward part ofthe fuselage 2 of an airplane (shown only by way of illustration) is-located an engine 4 (diagrammatic), to the rear of which may be placed a gasoline or other fuel tank 6. Between the fuel tank 6 and theengine 4, I place a tank 8 which may contain any suitable fire extlngulshing or smothering fluid or mixture. 'The tank 8 is pur-' posel constructed of light material with a low factor of safety by comparison with the fuel tank 6 and is adapted to cushion the impact of the fuel tank 6 in case of a nose crash. In order to ensure the breaking of tank 8 on impact suflicient to burst tank 6,-

with a number of spikes or other puncturing means 10 located within said tank 8 and directed toward the opposite wall of said tank. In the event of a crash these spikes -10 will ensure a positive series of holes being punched in the engine side of the tank 8.

In order to extinguish small fires which might arise duringflying, I provide a pipe system 12 from the tank 8 to the forward part of the engine where, a spray nozzle 14 is connected and where the slip stream or any air stream may aid in carrying the fire extinguishing'fluid over the engine to extinguish the flame. A valve 16 which may be operated "by a lever 18 is provided if desired.

Vhat I claim is 1. In a combination of internal combustion engine and fuel tank, a tank containing a fire, extinguishing mixture between said engine and fuel tank and directly adjacent said fuel tank and means forpiercing the a fire extinguishing mixture directly adjacent to said fuel tank and between said fuel tank and said engine and means within said second tank to rupture the same upon impact with said engine. s

In testimony whereof I aflix my signature.
