ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.

Application filed December 8, 19 20.

To all whom it may concern:

Be it known that I, lVaurnn W. GROOMS, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Attachments for Internal- Combustion Engines, of which the following is a specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention relates as indicated, to attachments for internal combustion engines and more particularly to a device adapted to reduce the amount of ,fuel used during the operation of the engine and also to revent the formation of carbon in the cylinders and on the spark plugs of such engines. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Fig. 1 is a view partly in elevationand in section showing my attachments as applied to an internal combustion engine; Fig. 2 is a plan view'of thecover of one of theparts showing an electricfswitchcarried thereon; Fig. 3 is a horizontal'section on the line 3-3 Fig. 1; and, Fig.- 4 is a section through a valve adapted I the parts.

The device as shown is adapted to beattached to an internal combustion en,

gine 1' and comprises a tank or receptacle 2 having a" cover 3 suitably held thereon. Passing through the cover 3 is a pipe 4having an L shaped extension .5 adapted to lie adjacent the bottom of the receptacle 2. The L-shaped extension 5 of the pipe 4 is provided with a plurality of outlets 6 the unction of which will be described later. The pipe 4 extends up through the cover 3 and is provided with a T-connection 7'from the two remaining openings of which extend pipes 8 and 9. The pipe 8 leads to an insulated box or container 10 in which is mounttosp pply water to oneot Serial No. 429,083.

ed a violet ray tube or ozonizer 11. Surrounding the tube 11 is a cylinder or casing 12 of metal to which a lead wire 13 is connected, this lead wire 13 being attached to one terminal of a spark coil 14. A second lead wire 15 connects the lower end of the violet ray tube to the other terminal of the coil which may be connected to the battery of the car or to a separate. battery which is not shown. An inlet pipe 16 is provided in the wall of the container 10 on the side opposite to that in which the pipe 8 enters.

Theipipe 9 is connected to the exhaust manifold 20 and is adapted to convey the burned gas or any necessary quantity thereof up to the entire amount, from the engine 1 through the T-connection 7 and the pipe 4 to the L shaped end 5 thereof and there permitted to escape through the perforations 6 into the receptacle 2. The pipes S and 9 are provided with valves to regulate the proportions of flow through said pipes.

The receptacle 2 is adapted to contain water the level of which is automatically maintained at a predetermined height. The receptacle 2 is provided with two openings 21 and 22 which are in line with two complementary holes 23 and 24 in a sl'naller receptacle 25 and are connected together by means of short lengths of pipe 26 and 27 securedin the holes 21 and 23, and 22 and 24 respectively Mounted in the receptacle 25 are two wires or guides 50 so disposed thatthe upper ends of each are positioned one quarter of a revolution in advance of the'lower ends thereby forming in effect a helical guideway for a float 28 which is slidably guided on suchwires 50 by means of a retaining strip 29 carried by the float 28 and provided with holes 30 adapted to engage around the wires 50.

Rotatably mounted centrally of the receptacle 25 is a shaft 31 on'which is slidably keyed the float 28 so that the said shaft will rotate therewith as the float is rotated yet will permit the float to slide up or down according to the amount of water in the receptacle'25. The shaft 31 is pivoted in the bottom of the receptacle 25 and passes through the cover 32 and has attached to the extending portion a contact arm 33 which is adapted to engage or contact with a terminal 34 carried by and insulated from the cover 32 a short distance above the ball 39 which will when the Water in the receptacles 2 and drops below a predetermined level.

When the contact arm -33 engages the terminal M the electrical circuit closed by such engagement operates a valve 35 which is adapted to permit water to flow into the tank 2. This valve may be connected to a Water pipe 61 communicating with the engine radiator so as to eliminate the use of a separate water supply tank if desired.

As shown in Fig. 4, the valve 35 comprises the usual ball check valve 36 with the additionof an-electromagnet I)? mounted thereon. The core 38 of the magnet extends within the casing of the valve 35and terminates be made of material adapted to be attracted 'by the'core 88 when excited. WVhen the circuit is broken the ball 39 Willclropback onto the valve seat 40 and cut off the water inlet.

I have also provided a water tank having a pipe 51 leading therefrom to the receptacle 2. The lower end of the pipe 51 terminates at the level of the Water in the receptacle 2 and this pipe is provided with a valve 52 adapted to regulate the flow of water therefrom. The tank 50 is airtight and is provided with a filler cap 53. As the water in the receptacle 2 drops below the predetermined level water will drop from the tank 50 through the pipe 51 into the receptacle 2 being displaced by air from the receptacle 2 until the Water again reaches a level to seal the lower end of the pipe 51.

Leading from the cover 3 of the receptacle 2 is a third pipe which is connected to the inlet manifold 61 at a point above the carburetter 62. In operation my device I works as follows: The circuit controlling the coil 14 is closed thereby operating the violet ray tube or ozonizerll. The operation of the engine creates a suction in the pipe 60 and a partial vacuum in the receptacle 2. This creates a suction in the pipe 4 and air is drawn through the inlet 16 in thebox 10 around the metal casing ahdthe violet ray tube 11 and by means of the electrical discharge created by the violet ray tube and the casing the air is changed to ozone and is carried by the pipe 8 to theT 7 where it mixes with the burned gas conveyed to the T 7 by the pipe 9. From the T 7 this mixture is conveyed by the pipe 4, and its L-shaped end to the bottom of the receptacle 2 and out through the perforations 6 into the water in the receptacle 2 through which it percolates and is conveyed through the pipe 60 to the inlet pipe 61 --mixture of gasoline and air can be used through the carbureter and also that the formation of carbon in the cylinders and on the spark plugs is practically eliminated. Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In a device of the character described in combination with an internal combustion engine having inlet and exhaust manifolds, a tank adapted to contain water at constant level,- a pipe attached to-said exhaust manifold adapted to convey burned gas to the bottom of said water tank, an ozonizer, a pipe attached to said ozonizer adapted to convey ozone to said first pipe between said exhaust chamber and said water tank, means vin said water tank adapted to permit such burned gas and ozone mixture to percolate through such Water in said tank, and a pipe attached to said watentank adapted to convey such mixture 'to the intake chamber of said internal combustion engine.

2. In a device of the character described in combination with an internal engine having an exhaust pipe, an intake pipe and a carburetor, a water tank adapted to contain water at a constant level, a pipe connected to theexhaust pipe of said internal combustion engine adapted to convey burned gas into said Water tank below the level of the water therein, an ozonizer, means for operating said ozonizer, a pipe connected to said ozonizer adapted to convcyozone to said burned gas conveying pipe outside of said water tank, means within said water tank adapttd to permit such burned gas and ozone mixture to percolate through such water in saidwater tank, and a pipe attached to said water tank above such water level adapted to convey the mixture in said watcr'tank to the intake pipe above the carbureter.

Signed by me. this 1th .day of December.
