AIR-MOISTENER.

secon, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements 1n A1r-Mo1steners; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to This invention relates to air a part of the combustible charge; and it consists in the novel construction and combination of the parts" hereinafter fully described and claimed. i 1

In the drawings, Figure 1 is a side view of an air moistener constructed according to this invention. Fig; 2 is a vertical section through the air and Water valves, and is drawn to a larger scale.- Fig. 3 is a. plan view of the same. Fig. 4 is a side view of the air moistener showinga modification.

A mixing chamber or pipe 2 is provided, for'air and for water in the form of fine spray, and is adapted to be connected to the intake pipe of the engine. ,This mixing chamber or pipe 2' is preferably passed through a heating-chamber 3 which is preferably the exhaust pipe or exhaust manifold.

of the engine, so that the contents of the mixing chamber may be heated by the waste products of combustion.

A valve casing 41: is provided, and is divided into two chambers by a diaphragm 5 of flexible material. The upper chamber 6, above the diaphragm, is an air chamber, and the lower chamber 7 is adapted to hold water or other approved moistening fluid.

The lower chamber 7 has a water inlet pipe 8 connected to it, and 9 is a valve of any approved sort for drawing off the i vlae lower chamber hasan outlet 10 for water at its bottom, and 12 is a needle valve which operates as a spray-forming device, and which controls the passage of water through the outlet 10.

The stem 14 of the needle valve is secured in a metal disk 19 which -is attached to the center part of the'diaphragm. The upper end portion of the valve stem 14 works in a guide 15 secured to the top of the casing.

moisteners for use 1n connection with mt'ernal combus-- tlon engines to molsten the a1r taken 1n as clearly seen. The connecting-piece has an The guide isscrewed in the top of the easmg so that its position can be adjusted, and

16 is a jam nut for locking it in place. .A

-helical spring 17 is arranged in the guide around the valve stem, and is arranged be-- tween-the guide and the-disk 19 so that the needle valve is pressed toward it seat and normally closes the outlet. Thetension of I g the spring 17 is varied by adjusting the positionof the guide. A stop stem 20 is provided and is screwed into the top end ofthe guide, and this stop stem projects downwardly so that the upper-end of the 'stem' of the needle valve 'may strike it. The stem 20 is adjusted to ,vary the lift of the needle valve, or to holdit closed, if necessary. I A

helical spring 21 is arranged between the 1 accidental displacement top of the guide and the head 22 of the stop' piece 24; is arranged between the lower part of-the casing 4 and the mixing chamber, and v is suitably secured .tothe said parts. Two large inlet'openings 25 forv air are formed in the middle part of the connecting-piece 24, upon opposite sides of-it, and these openmg's form sight-holes through which the feed of water from the needle valve may be inlet valve 26 which opens downwardly, or. inwardly toward the mixing chamberf This valve 26 is arranged below the level'of the holes 25, and it is normally seat by a light spring 27 A v The air space of the upper chamber 6' is connected-with the mixing chamber andwith held to its the intake of the engine by means of a pipe 30. In the form of the device shown in Fig. 1, this pipe 30 is shown connected to the mixing chamber or pipe after it has passed through the exhaust or heating pipe, and where the suction of the intake is con-1 siderable. in Fig. 4., the pipe 130 is connected with the.

In the form of the device shown mixing chamber or pipe before it enters the pie is shorter, than in a causes the flexible diaphragm to move upwardly and open the needle valve. The water rushes through the needle valve and is projected in the form of spray through the inlet valve 26 into the mixing chamber. The valve 26 is opened simultaneously with the opening of the needle valve, as the pressure in the mixing chamber is also reduced below that of the atmosphere, and the air rushes formation of large drops of moisture .and.

vaporizes any drops which may be formed and which fallto the bottom of the mixing chamber. This enables the air to carry a I large supply of moisture with it into the engine cylinder.

This moisture prevents the formation of solid deposits of carbonin the engine cylin der, which would greatly interfere with the satisfactory working of the engine. When the engine is not at work, and when its cylinder is not drawing in a new charge, the

action of the moistener is suspended, as water valve is not opened.

What I claim is:

1. In an air moistener, a mixing chamber, an inlet valve for the said chamber, a water valve, and an air-inlet piece' secured between the said inlet valve and water valve, said valves both being operated automatically and independently of each other when the pressure in the mixing chamber is reduced, and the said water valve operating to feed the water through the airinlet piece and inlet valve into the mixing chamber.

2. In an air, moistener, a mixing chamber, an inlet valve for the said chamber, a water valve, and' an air-inlet piece secured between the said inlet valve and water valve and having air inlet openings at opposite sides of it which form sight-holes for the feed from the water valve through the said inlet valve into the L mixing chamber, said valves being operated automatically and independently of each other when the pressure in the mixing chamber is reduced.

3. In an air moistener, a mixing chamber, an inlet valve for the mixing chamber, a casing, a diaphragm secured in the casing and separating it into a water chamber and an air chamber, a water valve controlled by the said diaphragm and operatively connected with the said mixing chamber, and a pipe connection between the said air chamber and the mixing chamber, whereby the said inlet valve and water valve are opened simultaneously when the pressure in the mixing chamber is reduced below that of the atmosphere.

4:. In an air moistener, a mixing chamber, an inlet valve for the said chamber, a water valve, and an air-inlet piece secured between the said inlet valve and. water valve and provided with a sight-hole for the feed from the water valve, said inlet valve and water valve being operatedautomatically when the pressure in the mixing chamber is reduced below that of the atmosphere.

5. In an air moistener, a mixing chamber, an inlet valve for the mixing chamber, a casing, a flexible diaphragm secured in the casing and separating it into a water chamber and an air chamber, a water valve controlled by the said diaphragm and discharging into the mixing chamber, a spring normally closing the said water valve, a stop for regulating the lift of the said water valve, and a pipe connection between the air chamber and the mixing chamber.

6. In an airmoistener, a mixing chamber, an inlet valve for the mixing chamber, a casing, a diaphragm secured in the casing and separating it into a water chamber and an air chamber, a water valve controlled by the said diaphragm and operatively connected with the said mixing chamber, and a pipe connection secured to the said air chamber and operatively connected with the delivery end portion of the said mixing chamber.

In testimony whereof I have aflixed my signature.

WILLIAM WYAND.
