HUMIDIFIER FOR INTERNAL-GOMBESTIQN ENGINES.

Application filed may 28, 1923.

To all whom it may concern:

Be it known that l, HOMER E. LAWRENCE,

a citizen of the United States, residing at Elgin, in the county of Kane and State of Illinois, have invented new and useful Imbustion engines and more particularly to humidifiers for the fuel thereof.

The primary object ofthis invention resides in the provision of a humidifier for an internal combustion engine, preferably an automobile engine, which will increase the explosive efiect of the fuel and tend to eliminate carbon deposits on the cylinder walls of the engine.

Another object of this invention resides in the provision of a humidifier, for an internal combustion engine, preferably an automobile engine of the water cooled type, which is adapted to be connected to the overflow pipe of the water cooling system for conducting the vapor in the top of the radiator and properly mixing it with warm air sucked therein prior to being discharged therefrom into the intake pipe of the carbureter. I

A still further object of this invention resides in the provision of a hutmidifier for an automobile engine of the water cooled type, which consists of an embodiment of elements capable of vaporizing any overflow from the radiator, mixing it with warm air sucked therein and discharging it into the intake of the carbureter, reduce the consumption of fuel and tend to eliminate the accumulation of carbon in the combus- 40 tionchamber of the engine.

In addition to the aforesaid objects, this invention resides in the provision of a humidifier, for automobile engines of the water cooled type, which is adapted to not only transform any overflow of the radiator into vapor and discharge it into the intake of the carburetor, but its embodiment of elements are so arranged that any excessive supply of water from the radiator will be discharged therefrom. 9

Aside from the aforesaid objects, this invention resides in the provision of a humidifier," for internal combustion engines, which not only segregates the vapor but permits warm air to commingle with the vapor Serial No. 841,683.

prior to entering the port to the. intake conduit to the carbureter.

With these and other objects in view, this invention resides in certain novel features ct construction, arrangement and combina tion of elements to be hereinafter set forth in the specification, illustrated in the ac companying drawings and pointed out in the appending claims.

in the accompanying drawings forming a part of this application: I

Fig. 1 is a conventional illustration of a portion of an automobile showing the elements of this invention in operative association with the radiator and carhureter thereof.

Fig. 2 is an enlarged side view of the humidifier per se.

Fig. 3 is a plan view thereof.

Fig. 4 is a longitudinal sectional View on line 44 of Fig. 3.

Fig. 5 is a similar view on line 55 of Fig. 3.

Fig. 6 is a plan view with the cover plate removed.

1Fig. 7 is a detail perspective of the cover p ate.

Fig. 8 is a similar view of the feed and discharge conduit removed from the humid- 1 er.

In the present illustration of this invention the letter A designates the front portion of an automobile which comprises the engine B, water radiator R having theusual overflow pipe 0, and carbureter 0 having the usual or any type intake pipe P.

Suitably secured between the overflow pipe 0 and intake pipe P is a humidifier 5 which is connected in communication with the outlet end of the overflow pipe of the radiator into the mixing chamber and conduct it therefrom bureter.

The exterior ends of the conduit 8 are deflected as at 8' and are connected to the to the intake of the caraforesaid flexible conduits 6 by suitable is a cover plate which is secured in vaportight relation therewith by screws or other suitable means and has an, inwardly protruding V-shaped deflector 11 adapted to extend within the substantially V-shaped port 9 of the conduit 8 to direct the incursion of vapor into the mixing chamber from one side thereof, and the excursion of vapor therefrom'from its opposite side.

Should the radiator discharge a greater volume of water than the humidifier can vaporize, under normal working conditions, the air inlet port 12 will function as an overflow.

In order to secure the humidifier in a rigid position so its successful operation is assured suitable clamping means can be secured thereto by the fastening elements 14 or other suitable'fastening means.

With this invention installed, in communication with the outlet end of the overflow pipe to the radiator and the intake pipe to the carbureter, vapor is discharged into the mixing chamber where it is mixed with warm air created beneath the hood of the engine and introduced into the mixeena-ya ing chamber through the port 12 and sucked into the intake of the carbureter by the suction of the engine pistons.

Having thus described this invention, what I claim and desire to protect by Letters Patent is:

1. A humidifier of the class described comprising a mixing chamber, a conduit extending therethrough and having a port in communication therewith, a cover plate for the mixing chamber, a deflector carried by the mixing chamber and having a substantiaily V-shaped port therein, a substantially V-shaped deflector extending into the V- shaped port of the conduit approximately at its medial point, and a cover plate supporting the V-shaped deflector.

In testimony whereof I aflix my signature.

HOMER ELLIS LAWRENCE.
