HYDROGARBON-MIX'IJURE HEATER.

Specification of Letters Patent.

\ Patented July 2, 1918.

Application filed April 7, 1917. Serial No. 160,514.

To GZZ' whom it may concern 'Be it known that I, WILLIAM A. PERKINS, a citizen of the United States, residing at Cortland, in the county of Cortland and State of New York, have invented new and useful Improvements in Hydrocarbon-Mixture Heaters, of which the following is a specification.

This invention relates to a heater especially adapted to be used for heating a hydrocarbon mixture as it passes through a manifold and before it is introduced into the engine cylinder and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a heater of simple and durable structure adapted to be applied to the manifold of an internal combustion engine at a point between the intake point of the cylinder and the carbureter, and which. is supplied by a heating medium conducted from the exhaust of the engine whereby the mixture is subjected to the heat prior to its introduction into the engine cylinder and thus is put in proper condition for explosion.

With this object in view the'device includes an enlarged portion in the manifold pipe at a point between the carburetor and the intake port of the engine cylinder and a casing inserted in the said enlargement. Suitable pipes connect the said casing with the exhaust pipe of the engine and short sections of pipe pass through the said casing and the inner portion of the casing is spaccd' from the outer wall of the enlargement, thus providing ample room to permit the mixture to pass through the manifold.

. In the accompanying drawing Figure 1 is a side view of an engine showing the heater applied. Fig. 2 is a vertical sectional view of the heater. Fig. 3 is a transverse sectional view of the same. Fig. 4: is a perspective view of the casing used in the heater.

As illustrated in the accompanying drawing. the engine. 1 is of a'usual type and is provided with a manifold 2 which in turn is connected with a carbureter 3 in a usual manner. The heater comprises an enlargement 4; provided on the manifold 2- at a point between the ends thereof. A casing 5 is inserted in the enlargement 4 from one side thereof and the inner surface of the said casing 5 is spaced from the outer surface of the enlar ement 4.. A suitable packing 6 is interpose between the outer wall of the casing 5 and the enlargement 4 and serves as means for closing the joint between the casing and the enlargement. Pipes 7 pass 10ngitudinally through the casing 5 and are spaced from each other. Any suitable number of pipes 7 may be employed. A pipe 8 is connected with the upper portion of the easing 5 and is also connected with the exhaust pipe 9 of the engine preferably at a-point where the said pipe 9 is heated the mostjn consequence of the exhaust gases passing through the same; A valve controlled funml 10 may be applied to the pipe 8 in the vicinity of the casing 5. A pipe 11 is conneeted with the lower portion of the casing 5 and may conduct the exhaust gases from the same.

In operation, the mixture is drawn through the manifold 2 and the enlargement 4 by the action of the engine piston in a usual manner. At the same time the exhaust gases are expelled from the engine cylinder and some of the said gas passes through the p pe 8 into the casing 5 and heats the same and the pipes 7 Therefore as the mixture passes along the sides of the casin 5 and through the pipes 7 it is subjecte to the heat and thus the mixture is heated prior,

to its introduction into the engine cylinder. As hereinbefore stated the gas. which enters the casing 5 may eseape from the same through the pipe 11; When it is desired to,

clean the heater of the accumulation of carbon or other foreign matter gasolene 1s poured into the funnel 10 and the valve thereof is opened whereby the said gasolene may gravitate into the casing 5 and .cut the said foreign material. loose which may pass out with the gasolene through the pipe 11. In a similar manner hot water may be introduced into the casing 5 to aid in starting the engine when the same is cold.

From the foregoing description taken in conjunction with the accompanying drawing, it will be. seen that a hydrocarbon heater of simple and durable structure is provided and that the same may be conveniently used for efficiently heatin ahydrocarbon mixture priorto its intror uction 106 into the cylinder of a hydrocarbon engine.

Having described the invention what is claimed is In combination with a manifold pipe hav ing a diametrically enlarged portion, a 5 heater comprising a casing inserted through the side of the enlargement, the surface of the casing being spaced from the inner surface of the enlargement and approximately parallel with the same, spaced pipes passin through the casing and means connected 10 with the side of the casing for introducin a heating, agent into the casing and aroun the pipes.

In testimony whereof I afiix my signature.

WILLIAM A. PERKINS.
