HYBROPEIEUMATZC VAFORZING APPARATUS FOR GAS-ENGINES.

.tpplieation filed June B7, 1916.

To all whom i5' may concern:

Be it known that l, Jarras G. Meermin', a

citizen of the United Sta-tes, residing at San ing and closing of the throttle; second, to

provide an apparatus of this class with a double diaphragm action, thus providing for great flexibility and a very sensitive action; third, to provide an apparatus of this class which is adjustable throughout, thus making it readily adaptable to various constructions' of engines and carbureters; fourth. to pro vide an apparatus of this class which admits a certain regulated quantity of air and a certain regulated quantity of water together in a vaporized form into the intake inanifold of the engine; and fifth, to provide an apparatus of this class which is simple and economical of construction, durable, easily installed and will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter my invention consists of certain novel features of construetion, combination and arrangement of parts as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the aecompanying drawings and to the characters of reference thereon which form a part of this speciiication, in which:

Figure 1 is a fragmentary side elevational view of an engine with the intake and eze haust manifold in connection therewith in dotted lines and showing my apparatus in connection therewith in solid lines. Fig. 2

is an enlarged sectional view of my appara-l tus minus the water receptacle and conducting tube connecting therewith and Fig. 3 is atop or plan view of the same.

Similar characters of reference refer to similar parts throughout the several views.

Specification o Letters Patent.

Patented lil, i917.,

Serial No. 106,153.

The 'l' shaped conducting member l, valve 2, adjusting screw 3, diaphragm member i, diaphragm member 5, lock nut 6, clamping nut 7, needle valvelscrew 8, liquid-conducting tube 9 and liquid receptacle l0 constitute the principal parts of my apparatus.

The member l is a hollow pipe member shaped as shown best in Fig. f2 of the drawings consisting of portions la, 1l and l. The portion la is externally threaded with a pipe thread adapted to lit into a threaded hole in the intake manifold of the gas engine The portion l is also provided with a valve Q therein adapted to close the hole through said portion la when desired. rihe portion l is externally threaded and on said threads is screwed the clamp nul 7 and also on said threads is screwed the reinforcing member 5 which is rigidly secured to the diaphragm member 5. This diaphragm member 5 is a circular piece provided with an upwardly extending flange 5b to which is secured an other diaphragm member el. which is provided with a downwardly extending flange 4 which over-laps the flange 5b to which it is secured preferably by means of soldering. lidounted centrally on `the diaphragm mem ber 4 is a reinforcing piece 4b which is centrally threaded adapted for the threads 8a on the needle valve screw 8. Said needle valve screw is supported on the diaphragm member 4 and is locked in certain positions relatively thereto by means of a lock nut 6. lt will be here noted that the needle valve screw 8 is supported in position by means of two diaphragm members thus giving it greatl flexibility of movement and making it very sensitive. The other end of the needle valve screw 8 is pointed at 8l and extends into a hole 1d with downwardly converging walls thus forming a needle valve in the portion l of the T member 1. Communicating with the lower end of this hole l1d is a hole le at right angles thereto extending to the outside of said'portion l and extending from the lower extremity of said hole ld is a small hole lf communicating with a large hole lg in the lower end of said portion lc. Mounted in the side of said portion l and extend ing into the hole 1f is the screw 3 which is adapted to regulate the size of the hole 1f from the outside by the turning of said screw 3 therein'. Upon the extended end of the portion lc is an external thread upon which is mounted the conducting tube 9 lit) ' ment substantially as set forth in the appended claims.

lt is obvious that with this construction there is provided a hydro-pneumatic vaporizing appartaus for admitting a regulated quantity olf vapor to the engine cylinders in proportion to the quantity of hydro-carbon roin 'the carburetor at all times, that the diaphragm' members 4c and 5 Will be actuated relatively to the vacuum in the intake manifold thus regulating the size oit the opening around the needle valve which controls the quantity of vaporto said intake n'ianifold, that the air inlet le being always open will prevent siphoning, that said air intake being; at right angles to the Water inlet Will cause a vaporization of the Water entering through the hole lf, that the quantity of air and Water in a vapor form to the intake maniiiold may be regulated and adjusted by the turning of the screw 8 into the diaphragm reinforcing piece 4b, that the relative quantities of air and Water may be regulated and adjusted by means of the screw 3, that the apparatus as a Whole is simple and economical of construction, durable, easily inl stalled, automatic in its action and Will not readily get out of order.

Having thus described my invention whatA l claim as new and desire to secure by Letters Patent, is:

l. In an apparatus of the class described, a vapor conductor provided with separate water and separate air inlets, means for regulating the quantity or vapor therethrough,

Lacanau said means consisting of a double hollow diaphragm communicating with said concluetor and a needle valve supported. by said diaphragms and means for adjusting said needle valve relatively to said diaphragm supports.

2. In an apparatus of the class described, a vapor conductor provided with separate Water and separate air inlets and means for regulating the quantity of vapor therethrough, said means consisting of a double hollow diaphragm communicating With said conductor, a needle valve supported by said diaphragms, means for adjusting said needle valve relatively to said diaphragm supports and manually operated means for closing said. conductor independent of said needle valve.

3. ln an apparatus of the class described, a vapor conductor provided with separate water and air inlets connecting with the intake manifold of a gas engine, means for regulating the quantity of vapor through said conductor, said means consisting of a double hollow diaphragm actuated by the vacuum in said intake manifold, a needle valve supported by said diaphragms, means for adjusting said needle valve relatively to said diaphragm supports and means for adjusting the size of the Water intake to said conductor. e. In an apparatus ot' the class described, the combination of an intake manifold to a gas engine, a T shaped conductor rigidly secured thereto, means adjacent to said manifold for manually closing said conductor, a hollow double diaphragm communicating with said conductor, a needle valve adjustably mounted on said diaphragm whereby said needle valve is automatically opened and closed relatively to the vacuum in said intake manifold, means for supplying Water and air to said needle valve, and means for regulating the quantity oit' Water to said needle valve.

In testimony whereof, I have hereunto set my hand at San Diego, California', this 21st day of June, 1916.

JAldES MECHAM.
