AIR-WASHING J ATTACHMENT FOR CARBURETORS.

' Application filed April 2a, 1918. Serial No. 230,199.

To all whom it may concern:

Be it known that I, JAooB L. WELLS, a

citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Air-Washing Attachments for Carburetors, of which the following is a specification.

' The object of my invention is to provide an attachment for an internal combustion engine carburetor by means of which the air entering the carburetor may be thoroughly washed and purified to the end that the entrance of dust and dirt into the carburetor will be entirely prevented.

A further object is to provide an attachment of the class described in which the air entering the carburetor in addition to being thoroughly washed, is moistened. and thereby a better and more efiicient mixture for the gas charge isobtained.

Other objects of the invention will ap-- pear from the following detailed description.

The invention consists generally in various constructions and combinations. all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a side view of an internal combustion engine and radiator with my invention applied thereto,

Figure 2 is a vertical sectional view through the attachment for the radiator,

Figure ills a horizontal sectional view on the line 33 of Figure 2,

Figure 4 is a vertical sectional view of a modified construct-ion, attached to an exhaust manifold.

In the drawing, 2 represents an internal combustion engine of any suitable type and 3 a carburetor therefor, 4 is the radiator, of any suitable construction having a pipe connection 5 with the jackets of the engine cylinders. On the top of this radiator I mount a casting 6 having a chamber formed therein of suitable size and shape to receive the upper end of a section of pipe S which is preferably supported bymeans of a spider 9 in the upper end of the pipe and a rod-1O which is tapped into said spider and is provided with a finger grip 11 on the top of the casting 6. The pipe 8 is open at each end and the wall of the casting has a plurality of ports 12 therein communicating with the pipe 8 and throu h which air is drawn into the radiator. n elbow 13 is formed in the casting 6 and has a passage 14 therethrough and a port 15 is provided in the Wall of said elbow in the upper part of the castingti communicating with the chamber 16 in the top of the radiator. The lower end of the elbow13 has a coupling 17 in the wall of the radiator to which a pipe 18 is connected, which extends to the carburetor 3. This pipe forms an indirect air intake to the carburetor. Through this pipe a suction will be established to draw air through the perforations12 into the pipe 8, the lower end of which is submerged in the water in the radiator and down'through the open lower end of the pipe and up through the water in the radiator to the elbow 13, and from thence to the carburetor. During this pas sage the air will be thoroughly washed and cleansed and at the same time will be moistened 'so that whendelivered to the carburetor it will be free from all impurities or any foreign substance which might clog the carburetor or interfere with its proper operation and will he moistened to such an extent .that combustion of the charge in the cylinders will be more complete and the operation of the engine more efiicient.

I am aware that it is known to connect the circulatin system of the motor with the manifold of the engine for the delivery of vapor to the mixing chamber, but this does not accomplish the result obtained by my invention as no provision is made .for cleansing the air which enters through the carburetor, and this is the essential feature of my present invention. I prefer also to provide a valve 19 in the wall of the carburetor, operated by a rod 20 from the dash so that whenever desired, as in starting the engine, the operator may admit air directly to the carburetor until suflic-ient suction is created to draw the air through the pipe connections with the circulating system.

In Figure 4 I have shown a modification, which consists in providing a casing or housing 21 around the exhaust manifold 22 through the water and around the hot walls of the exhaust pipe and is heated thereby and then enters a nipple 26 in the top of the casting: for delivery through a pipe, connection 2 with the carburetor, as described with reference to Figure 1.

This manner of washing the air is substantiallythe same as described with reference to the previous figures, except that the housing 21 is a separate attachment for the exhaust pipe instead of attaching the pipe connection of the carburetor with the circulating system. a

My attachment aidscombustion by adding' air in a heated condition. It assists in controlling the temperature of the engine and in controlling and preventing preignition of liquid fuels, and also prevents carbonization in the cylinder and aids. in the use of low grade fuels.

I claim as my invention:

1. The combination. with an internal combustion engine carburetor, of a radiator and casing mounted thereon and having perforations in its walls, a pipe open at each end fittingwithin said casing and communicating with said perforations and having its lower end depending within the water in said radiator, means for adjusting said pipe to increase or decrease the volume of air intake, said casing having an elbow formed thereon, one end of said elbow communicating with the space in said radiator above the level of the water and the other end having a coupling in the wall of said radiator and a pipe leading from said coupling to the carburetor.

2. The combination, with an internal combustion engine and its carburetor, of a radiator, a casing mounted thereon and having1 a plurality of air intake openings in its wa ls and a pipe having open ends n'iounted for adjustment in said casing for exposing or closing said air intake openings, one end of said pipe being immersed in the water in the radiator, whereby the air currents entering said openings fiow downwardly through said pipe and the water in said radiator, said casing having a chamber above the level of the water and a pipe having an open end in said chamber and pro vided with means for connection with the engine carburetorw In witness whereof, I have hereunto set my hand this 13th day of April 1918.

- JACOB L. WELLS.
