APPARATUS FOR MOI STENIN CARBURE'ITED MIXTURES FOR GAS-ENGINES.

' I A 4. Application filed To all whom it may concern: j A Be it known that .1, WILLIAM- MILLARD, a subject of the King of Great Britain, residing at the borough of Manhattan, city, county, and State of New York, have .in-

vented certain new and useful Improvements in Apparatus for Moistening Carbureted Mixtures for Gas-Engines, of which reted mixture that is burned' in the working the following is a specification, reference being had t the accompanying drawings.

. This I invention relates to improvementsv in apparatus for impregnating a combustible gas with water vapo'i, and particularly to improvements in apparatus by means of which air-is made moist and is'then incor porated, in a moist condition, in a carbuvl cylinder of a gas-engine, or likem'otor, of

an automobile; and an object of this invention is to provide an apparatus of the char-. acter just described which will. prove simple in construction, comparatively .cheap in manufacture and efficient in operation. and

use. Another object of this "invention is to provide an apparatus of the li nd hereinbefore referred to by means of which the resultsobtained will be uniform n character,

Other.features of thisinventionwill be referred to hereinafter. 1

In the drawings illustrating the principle of this invention and the best mode now known to me of applyingthat principle,

Figure 1 is a central vertical section-through the tank or reservoir of the air-moisten'er; F ig. 2 illustrates the latter connected to the intake manifold of a gas-engine or like motor; Fig. 3 illustrates a modification of the construction shown in Fig. 2, the air-mo is' tener being connected to the carbureter; Fig.

it shows, -in central vertical section, a modified torm'of the air-moistener illustrated in Fig.1, the admission of the air bemg-co-ntrolled by a valve arranged over an air opening in the base of the reservoir or receptacle that 'holdsthe Waterfors0lution; Figs. 5 and 6 are fragmentary sections in which a flap valve and .a ball valve, respectively, are shown; and Figs. 7 and 8 are plan views showing the disklike check valve of Fig. 4: and the flap valve of Fig. 5, respectively.

a denotes a cup-shaped, transparent vessel which serves as a receptacle for holding water or a suitable solution 6 andthe exterior of the mouth of Which is formed with Specification of Letters Patent.

. Patented screw-threads c, by the provision of which one is enabled to screw, upon the receptacle a,'-1ts cover (1. In the latter, there is formed "an opening f which is normally kept closed by means of 'a stopper 9, which is screwed thereinto and which, when it is desired to -replenish the supply of Water 6 in the ves- 'between the mouth of the'vessel a and the inner face of the'cover d and serves to make the joint between the vessel "and its cover air-tight. Near'the center of the cover (I, there is formed a boss J1, having, in its top, a socket or cavity h. The bottom it of the socket it serves as a supportffor'the valve i,

which is screwed into the bottom 71, and

which is formed with a disklike head 2",

downwardly from the boss h, there extends I anair-tube 7', the central passage. 7" in which communicates at its-,upper end with ports formed in the bottom it of the socket h. By turning the milled head i of. the valve 2', the position of the same may be so adjusted asto close entirely the ports is, leave them fully open or close-them only partially, whereby'the amount of air admitted to the air-passage y" may be regulated. A vertically-extending leaf-spring m is arranged adjacent to the boss h and is provided, at its upper. end, with a detent or catch m that is designed to engage automatically in the milled, peripheral surface 2' of the valve-head z" and serves thus to retain the valve in its adjusted position. The lower end of up. air-tube j is formed with openings or ports .j-through Which the air escapes from the air tube-j and passes into the water I), through which the air flows up- Jan/27, 1920.

As is shown in Fig. 3, the discharge end of 5 the conduit 'n/may be arranged to empty into the carburetor 7), instead of directly intothe intake manifold 0. Indeed, the' point of attachment of the outlet end of the conduit n is immaterial, so long as the moistened air from the water-containing reservoir (1 is permitted to mingle with the working fluid.

or other suitable material cemented at g" to the bottom of 'the vessel a and having intersecting cuts near its center; and the cut portion overlies the air-opening a-,. In the modification illustrated in Fig. 5., the

air-opening a is controlled by a flap valve r secured to the bottom of the receptacle (1 b means of the fastener r. In Fi 6 there is shown a modified form in which the boss h projects downwardly from the base of the vessel a, while escape of water through the airypassage s is prevented by the ball-shaped check-valve s, the casing s""of which is formed with ports t for the flow of the incoming air into the water Z).

Instead of water, a mixture-of water with alcohol may be used to moisten the air; and

a solution of hydrogen peroxid may be made to serve the same purpose. Other suitable solutions will readily suggest themselves to all skilled in this art. 4

I claim:

A unitary air-moistening device comprising a reservoir adaptedto contain liquid and air and having formed directly in and by one of its walls a passage intermediate the lower portion. of its interior and the at- "mosphere, a valve applied directly to and carried by the said wall of the reservoir and which controls the flow of air through said passage into the lower portion of'tlie reservoir, and a conduit carried by one wall of the. reservoir, in communication with the upperportion of the interior thereof and capable of direct connection to a conduit for ca-rbureted air.

Signed at the borough of Manhattan,

city, county and State of New York, this fourteenth day of Xovember, A. D. 1917, in the presence of the two undersigned wit-. nesses.
