COOLING "DEVICE FOR EXPLOSlVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 734,356, dated July 21, 1903. Application filed December 30, 1902. Serial No. 137,197. (No model.)

siding at Fiirth, in the Empire of Germany,

(whose full postal address is Maxstrasse 8, Fiirth, aforesaid,) have invented a certain new and useful Cooling Device for Explosive- Engines, of which the following is a specification.

The present invention has for its object an easy and rapid method'of emptying the water-pipes and water-cooling chambers of combustion-engines.

The improved means consists in closing the inflow-pipe to the reservoir or water-supply pipes and connecting it instead with the water-discharge pipe, by which means any water standing in the cooling-chambers of the engine and of the series of pipes is forced by means of air-pressure into the inflow-pipe in a direction opposite to that in which the water flows when the engine is at work in order to expel the water through the discharge-pipe, which is placed in communication withthe inlet-pipe.

The invention is shown diagrammatically in one form of construction in the accompanying drawing as applied to a combustionengine.

Both the working cylinders a of the combustion-engine and the pistons 17 of the same are provided with internal watercooling chambers c and d The cooling-water flows in through an admission-pipe u and a connecting-pipe 6 into the cooling-chambers c of the working cylinder and also through a connecting-pipe f and a telescopic pipe g it into the cooling-chamber d of the working piston. From the cooling-chambers o and d the water flows through a connecting-pipe v1 and a telescopic pipe is Z into the common dischargevessel is connected an air-pipe 5', provided with a-closable tap t. This air-pipe is connected with a blast or like device for producing compressed air at a higher or lower pressure. Thus if the tap t be opened, the cook 10 closed, and the water-supply pipe 10 shut oif from the farther part of the water-supply pipe by the closing of; the tap 0, and placed instead in communication with the dischargepipe n by opening the cock q, the compressed or blast air flowing through the pipe 8 into the chamber r penetrates into the series of pipes, expelling the water standing in the cooling-chambers of the engine in the opposite direction to that in which the water flows during the working of the engine-that is to say, from the said chambers into the inflowpipe u, from which it escapes through the discharge-pipe n.

I declare that what I claim is- In combination with an engine having a water-jacket, Water-circulating pipes therefor, a compressed-air pipe connected with the circulating-pipes and valves in said circulating-pipes whereby Water may flow into the jacket or be forced therefrom, substaptially as described.

In witness whereof I have hereunto set my hand in presence of two Witnesses.
