ing at Boston, in the county of Sufiolk and State of Massachusetts, have invented a new and useful Fuel-Heating Apparatus for its ternal-Combustion Engines, of. which the following is a specification.

. The present invention appertains to means for heating the gasolene or fuel which is supplied to the carburetor of. an internal combustion engine, whereby the gasolene or fuel will be properly and thoroughly vaporized in the carburetor, and under all atmoe pheric conditions, in order that the maximum efiiciency is derived from the fuel.

It is the object of the invention to utilize the hot water flowing from the water jackets of the cylinders as a medium for heating the gasolene or fuel flowingto the carbureter,

and to this end there is a unions combina-'.

The invention is illustrated in the accompanying drawing wherein the figure is an elevation of apparatus applied to an internal combustion engine, portions being broken away, and'the hot Water reservoir being shown in section.

In the drawing, there is delineated an in ternal combustion engine 1, which is to be taken as typical only, and the cylinders of which are connected to the intake manifold 2, which in turn is connected to the carbureter 3. A copper or similar fuel or gasolene pipe 4 extends from the carburetor 3 to the. fuel or gasolene supply tank 5 in the usual manner. The radiator is designated Q by the numeral 6, and the water-jackets of the cylinders by the numerals 7.

In carrying out the invention, a portion of the fuel supply pipe 4 is confined within a reservoir or container 8, that portion of the fuel pipe 4 within the reservoir 8 being coiled, as at 9. The reservoir 8 formsa portion of the water circulating system of the engine, or a portion oi the hot water lPatented'vla-tn; all, tel-list,

duit extending from the water jackets the radiator, and to this end a hot water pipe it) is connected at one end to the upper por tion of one'endmost water jacket "T, and is connected at its other end to one end of the reservoir 8, A pipe 11 ,15 connected to the other end or" the reservoir 8 and to the lower ion. of the radiator 6, and pipe. 12 con her; water jacket The usual pump (not shown) may be interposed in the water sir culating system at any suitable point, for

to the radiator 5 and the other endmost I causing the water to circulate properlythrough the water jackets and radiator.

The hot water reservoir 8 may be located at any suitable point between the engine and fuel tank, it' being noted that the coiled per tion 9 of, the fuel pipe 4:- is arranged contiguous to or within a portion of the hot water conduit which leads from the water jackets to the radiator.

In operation, the hot from thewater jackets 7 will flow through the hot water pipe 10 into the reservoir 8, and 'will flow around the convolutions of the coil 9 or: thefuel pipe. From the reservoir 8 which is interposed 1n the hot water pipe connecting the water jackets and radiator,'

the water flows through the pipe 11 into the radiator, and the cooler water flows back into the water ackets by Way of the pipe 12. The gasolene or other fuel in flowing through the coils Q-Will be heated by the hot.

water, and the gasolene or fuel is thus prepared for ready and efi'ective vaporation within. the carburetor. The gasolen'e is thus vaporized more readily under all atmospheric'conditions, and the present apparatus will eliminate the Waste incident to the use of cold-gasolene or fuel, and the-apparatus is of advantage for numerous other reasons which will suggest themselves to those versed in the art.

Having thus described the invention, what is claimed as new is: The combination with the water jackets of an internal combustion engine, having a lower inlet and an upper outlet, a radiator having a lower inlet below said jackets, and a carburetor, of a cool water pipe connecting the radiator and the inlet of said jackets, a hot water reservoir disposed b tween the horizontal planes of the radiator inlet and the outlet of the jackets, a hot water pipe connecting the outlet of the jackets and hi e and at mid reservoir, a oneness fii'cfigiil other arm 01' sald reservm'c :m the inlet o In tesmmony that X (31mm the toregomg as the rad-iatar .so that the hot Water flows my own, I havs hereto afiixed my signaidure 1e downwardly from the jackets inta said Yesin the presence of twu witnesses.
