H MrnrrIER;

Application filed May 22, 1924. Serial No. 715,244.

To all whom it may concern: V

Be it known that I, PHILIP VIvIANo, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in I-Iumidifiers, of which the following is a specification.

This invention is in the way of a humidilier' for explosive engines, and the object is to provide a relatively efficient and practical device of this kind. A further object is to provide a device of this nature which will operate to inject a continuous flow of live steam into the mixing chamber of the carburetor.

In the drawing- Figure 1 is a longitudlnal section through the device as attached to the exhaust manifold of the engine, the manifold being shown in cross section;

Figure 2 is a side elevation of the engine manifold with this improvement installed;

Figure 3 is a top or plan view of the device as attached to the manifold, the water tank, however, being omittedya portion of a carburetor being shown, together with portions of the connecting tube leading from the humidifier to the carburetor air intake; Figure 4 is a detail view of the boiler and integrally formed steam chamber and connecting elbow.

In carrying out this invention, I provide a hollow casting 1,'which embodies a small wedge-shaped boiler 2, closed at the end 3 and having a water chamber l leading into the boiler 2, and the steam chamber 5 immediately over the water chamber 4 and opening downwardly thereinto. A threaded nipple 6 is formed .at the upper part of the steam chamber 5 and the steam duct 7 leads out through this nipple. Back of the steam chamber 5, the casting takes the form of an upwardly turned connecting elbow 8, .interi-orly threaded at 9. The casing walls demarking the steam chamber 5 from the elbow 8 are brought down to a point 10, which may be styled the low water point, for a rea son later explained.

5 screw threaded at the point 11, and is so The casting 1 is turned and exteriorly threaded bottom 15, and a water pipe 16 threaded at its lower end to engage the threaded elbow 8. A small steam tube17 has threaded'engagement at one end with the nipple 6, while the opposite end is extended into the air intake of the carburetor. S0 assembled, the wedge shaped boiler 2 is located within the exhaust manifold where it becomes heated by the escaping products of combustion. lVater flows from the jar 14 into the water chamber 4 and boiler-2. Steam is formed in the boiler 2, and owing to the wedge like shape of the interior of this boiler, the steam flows out easily and naturally and up into the steam chamber 5 and thence through the tube 17 into the carburetor. When the water falls below the point 10 in the chamber 4, a bubble of air or steam. passes the point 10 and up into the jar 14, allowing more water to flow from the jar down into the water chamber 4. The wedge like formation of the boiler 2 isvery important, since if this boiler were formed strictly tubular, steam would form at the inner closed end and wouldbe forced out in the form of repeated explosions, instead of flowing out gradually as formed, as with the present construction. i v

While I'have herein described a certain specific manner and method of constructing t and assembling the elements of my inven- 35 tion, it is understood I may vary from the same in minor details, not departing from the spirit of myinvention, soas best to construct a practical device for the purpose intended, as defined in the appended claims.

I" claim: Q

1. In combination with the exhaust manifold and carburetor of an explosive engine, a device of the kind described, comprising a hollow casing embodying a wedge shapedboiler portion adapted for seating horizontally into the manifold, with the plane medially separating the wedge faces of the said boiler portion disposed horizontally, a water chamber leading-into the boiler, a steam chamber over the water chamber and communicating therewith, and an upwardly turned connecting elbow back of and separated from the steam chamber; a tube leading from the steam chamber into the air port of the carburetor; and a water jar mounted over and upon the connecting elbow of the casing. I

2. In oombination with the exhaust manifold and carburetor of an explosive engine,

a hollow casing embodying a wedge like boiler portion adapted to seat horizontally 5 into the manifold, with the plane medially separating the wedge faces of the said boiler portion disposed horizontally, a steam chainher for directing steam toward the carburetor, and an upwardly directed connecting elbow for supporting a water jar. 10

In testimony whereof I afiix my signa ture.

PHILIP VIVIANO.
