ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.

Application filed May 10, 1917.

attachment adapted to beiconnected with thev carbureterof an internal combustion engine, by means of which steam and water are drawn from the radiator of the-engine and delivered into said carburetor in a superheated condition by action of the heat radiated from the exhaust of said engine.

Another object of the invention is to pro vide an attachment of this character which when applied-to an internal combustion engine is adapted to increase the speed or power of the motor, effecting a saving of.

gasoleneand oil, and preventing the deposit of carbon uponthe interior of the cylinders and other parts thereby keeping the spark plugs and valves free from obstruction.

A still further object of the invention is to provide a simple and compact attachment of this ';-character readily. applicable to various types-of internal combustion engines, which isfadapted to utilizetheheat radiated from the .exhaust pipe to perform the super-heatingfunction.

A still further objectof the inventionis toprovide a device ofthis character which is easily andsimply constructed, inexpensive to manufacture, and one which willbe very eliicientyin, operation.

W'ith these and numerous other objects in view my invention consistiof the novelfeatures of construction, combination, and arrangement of, parts which will be herein referred to, and more particularly pointed out in the specification and claims.v

form of the super-heating chamber applied to the exhaust pipe.

In describing my invention I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views. InFig. 1 I have shown the device attached to the conventional form of the exhaust manifold 1 of an internal combustion engine, the intake manifold being represented at 2 and associated with a conventional type of carburetor 3, these various parts being of the type generally used in internal combustion en gines.v The parts above enumerated form the parts to which the attachment is connected and with which it is associated to carry. out the function to be hereinafter more fully described. i I

The numeral 4 designates a jacket of any desired shape, preferably cylindrical as shown in the accompanyingdrawings, and.

surrounding a portion of the exhaust pipe 1. This jacket is spaced from the wall of the pipe 1, as clearly shown in Fig. 2 of the drawings. Positioned within a jacket is the super-heating chamber 5, which is connected by a pipe v6 extending upwardly through the jacket 4- and adapted to be connected into the top of the radiator which is associated with internal combustion engines. radiator is not shown, the same being of the conventional type ordinarily usedin devicesof this character. The jacket t is connected with the carburetor 3 by. means of a pipe 7, said pipebeing adapted to be formed in any desired shape, accordingto the type of engine to which the device is applied,.in some instances it being necessary, tomake the same flexible;

,The preferred type of super-heating chamber employed in this invention consists ctheexhaust. pipe, and. to be; positioned on the same as, clearlyshown in'F-ig; 2 of the with a pair ofvehtpipes 9 thatextent from one end at the lowest point as clearly shown in Fig, 3, the said pipes being adapted to The carry off any unvaporized water from said chamber. The pipes 9 extend through one end of the jacket 4, and are carried to any suitable point for dischargingthe water.

In Fig. l. is shown a slightly modified form of super-heating chamber which is designated by the numeral 10, the same comprising a zigzag pipe extending across the portion of the exhaust pipe 1 which is inclosed by the jacket 4, said pipe having a plurality of spaced perforations 11 through which steam is adapted to escape into the jacket. The pipe extends through one end of the casing to carry off the unvaporized water, the other end of said pipe being connected with the pipe v6 which extends to the radiator of the engine.

'- In operation, it is obvious that the steam and water will be carried from the topof the radiator or fromthe water tank, through a the pipe '6 t0 the super-heating chamber 5. In this "chamber the vapor will be superheated and the steam will beforced throughthe perforations 8, or '11 accordpipe 7 to the carbureter 3.

ment is very simple, and may be econ0mi-' rally: constructed, and owing to its ex,-

ing to the form used, into the interiorof the jacket 4. From the jacket 4:, the superheated vapor is carried througl i the outlet his attachtreme simplicity, the same is applicable to various types of internal combustion enthe 4 may gines, with practically no change to the structure thereof. The

attachment will greatly increase the efliciencyvor durability of the engine,:as it will effect a saving of' asolene and oil, and remove carbon from interior of the cylinders thereby keeping the spark plugs and valves clear of,

the deposit of carbon. The pipe 10 in Fig. extend longitudinally in the jacket 4 if so desired From the foregoing description, taken in 'connection with the accompanying drawings, the advantages of the construction and of the method of operation Wlll be readily apparent to: those skilled in the art I i to which the invention appertains,

whileI have described the principle of op eration of the invention, together with the device which I now consider to be-the best embodiment thereof, I desire to have it understood that. the device shown is merely illustrative, and that such changes may be iiia'de. when desired as are within the scope oftth'e claims appended hereto.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In combination with the exhaust manifold. of an internal combustion engine, of

a jacket entirely surrounding the exhaust manifold and closedat the ends and adapted to communicate with the carbureter, an arcuate chamber within the jacket and bearing at one side upon the exhaust manifold and with the other side perforated and spaced from the jacket, and an intake communicating with the chamber.

2. The combination with an internal combustion engine includingthe exhaust manifold and the carbureter, of a jacket entirely surrounding the exhaust manifold and closed at the ends and communicating with the carbureter, an arcuate distributing chamber within the jacket and bearing at ;one side upon the exhaust manifold and spaced at the other side 'from the jacket, the spaced side of the chamber being perforated, and an intake'communicating with the chamber.

3. The combination with an internal combust-ion engine including the exhaust mani- REX c. BURNETT.
