ful Explosive-Engine, of which the followin is a specification.

h1s lnventlon relates to exploslve engines and more especially to the construction of the jacket surrounding the cylinders, one

object being to provide a novel arrangement of passages whereby the exhaust gases can be directed through the jacket and will serve to maintain the gaseous fuel at a high temperature. I

A further object is to provide means whereby the water used as a cooling medium will not extend between said passages and the outer wall of the jacket, but overheating and warping of said wall will be prevented by steam generated in the jacket, so that it becomes possible to maintain the gaseous fuel at a higher temperature than could be attained should water only be used as a cooling medium.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination and arrangement of parts and'in the details of construction hereinafterdescribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a view partly in plan and partly in section of the cylinder casting of an engine. Fig. 2 is a view partly in elevation and partly in section of said cylinder casting. Fig. 3 is a view partly in end elevation and partly in section of the casting, the section being taken on the line AB Fig. 1.

Referring to the figures by characters of reference 1 designates a cylinder casting of the usual construction having spaced exhaust passages 2 between which is provided a fuel intake port 3 opening into a chamber 4. Valves 5 are provided for closing the exhaust passages and additional valves 6 are utilized for controlling the flow of fuel from the chamber 4 to the respective cylinders.

The usual water jacket is employed but the water contained within the jacket is not designed to flow between the chamber .tand the passages 2. Instead a partition 7 extends within the casting so as to divide the water acket into a water containing chamber 8 and a steam chamber 9, this steam chamber being arranged between the partition 7 and the adjacent side wall of the cylinder casting. A desired number of ports 10 are provided within the partition 7 and each of these ports is designed to be partly or entirely closed by a valve 11 the stem 12 of whlch extends through the wall of the castmg and may be rotated in any suitable manner, as by means of a wheel 13.

While the engine is in use the valves 11 are moved so as to permit the leakage of a small amount of water from the chamber 8 into the chamber 9 and as the walls of the castmg are heated to a high temperature by the hot gases exhausted therefrom, it will be apparent that as the water is admitted in small quantities to the chamber 9 it will be immediately converted into steam. This steam, while having a chilling influence upon the wall of the casting so as to prevent warping thereof, will maintain the gaseous fuel within the chamber 4 at a much higher temperature than would be possible should water circulate freely in the chamber 9. Consequently the efficiency of the engine is greatly increased inasmuch as it is possible to keep the temperature of the fuel but slightly below the temperature at which it will ignite in the explosion chamber. Obviously valve 11 can be regulated so as to vary the supply of water to the chamber 9 to meet diflerent climatic conditions and to insure the maintenance of the heat of the wall at approximately a predetermined temperature. A steam vent 14L may be provided in the top of the chamber 9 so as to obviate the danger of explosion due to steam pressure within the engine or radiator.

What is claimed is 1. In an explosive engine, a cylinder casting having a water jacket and a steam chamber, valved means for controlling the admission of water to the steam chamber from the water jacket, and exhaust and fuel passages extending into the steam chamber.

2. In an explosive engine, a c'ylinder casting having a water jacket and a steam chamber, valved means for controlling the admission of .water from the water jacket into the steamchamber, and exhaust and fuel Patented-Jan. as. tart.

passages extending into the steam chamber, said steam chamber having a vent.

3. In an explosive engine, a cylinder casting having a water jacket, exhaust and fuel passages extending into the casting, a partition within the casting and providing a steam chamber extending between the passages, said partition having a port for maintaining communication between the water jacket and the steam chamber, and means for controlling the flow of water into the steam chamber from the jacket.

4. In an explosive engine, a cylinder casting having a steam chamber, means for admitting Water in minute quantities to the steam chamber from the water jacket, and
