reizende eem. 29,1914.,

Applioet'on led May 15, 1313. Serial No. 'm7,943.

To all whom it may concern:

Be it known that ll, linnninoii lllnnoLn,

e citizen of the United States, residing et Marion, in the county o1" ll/lerion and Stute e of lhio, have invented n new and useful Mixing-Valve for lExplosivelngines, ol'

which the following is a specification.

'llhe present invention eppertains .to mix ing valves for explosive or internal comwl; bastion engines, and aims to provide :i novel and improved device of that character for edmixing Water and oir eo that the mixture me be drawn into the cylinders with the car ureted ges.

lt is the object of the present invention to provide a valve of the nature indicated, which shell be of such construction and operation as to normally preclude the prr sage of-weter and eir therethrough, but permitting the Water and oir 'to be drawn or sucked inwardly and then admired so to be supplied to the cylinder or Cylinders.

Another object of the present invention is to provide novel and improved ineens for simultaneously shutting oli end establishing, the liow of air and wetervtliroogli the velve.

lt is also Within'the scope or? elle invention', to improve generally lthe eonetruetion eiid utility of devices of that ober-enter to which the present invention relates, 'in order that the device may be simple, compe-ce, durable and inexpensive, es well eseervieeeble, con venient endeiiicient in its use.

1With the foregoing generell obje-ete ont lined end with other obieete in view, i bieb will be apparent es the description proceeds, the present invention resides in the binetion end arrangement. o?? parte end in the details of construction hereinafter described and claimed, it being understood tliet ehengee in the precise embodiment of invention be mede'witbin the scope el' what is oleirned withone ,departing from lle spirit of the invention.

The invention me been illustrated in its preferred embodiment in the accompanying drawing, Wherein:- Figure l is a Alongitudinal central section of the valve. lig. 2 is e side elevation. Fig. 3 is e sectional View teken onv the line of wofl'dig. i i

In,v marrying ont the nventiomreference being had in detail to the drawing, there.

.parte ne will hereinafter appear.

indirectly to the engine cylinder, intake manifold, or other Suitable part of the engine, in order that the mixture of Water und oir may be drown inio the cylinder or cylinders. The mixing chamber l is also provided with en upper opening pro-vided by the socket 3.

An annuler inelnber el is seated on the rim of the Socket 3 end is provided with e reduced extension or nipple 5 threaded into the socket 3, '.lhe ennnlns is also provided with an upetnnding yoke or arbor providing e Supporting iframe lor certain of the 'lhe intermediate portion or crest ol' the yoke 6 is formed with :in opstanding lng or boss 7 hzuf'ing a lateral extension 8 over one nrni of the yoke.

A tube 9 hee its upper end threaded into the intermediate portion or heed of the yoke t? eo ee to depend within the yoke und wit-hin the emiulus Il and its exteneion'or nipple y5, the lower end ol tbe tube belng provided with e eons'tricted doet or openingr l0. A channel or duet ll entende from the extension 8 into the bose 7 so :in to connnunicate with the upper end of tube 9, the eX- teneion-' being provided with :i Socket or top 1i? for the reception of the end of a weiter enpply pipe. '"lliif water supply pipe iney be oli any snitirble character and may eomnninieete with eny convenient sour-ee ol weiter or similar lioid,

il .needle velve 13 is threaded tln-ough the loose end. extends axially Within the tube 9, the lower end or tip of the needle valve 13 cooperating with the duct or passage 10, end the opper end being projected above the boss 7 and eo formed sie to be conveniently turned or rotated by hand.

lA sleeve 11i is slidable snugly upon the tube 9 and passes through the extension or nipple 5 of the annulus 4, the lower end of the sleeve 14. being provided with en lannuler exterior Harige l5 projectingr below the rim or edge of the extension or nipple 5. The flange l5 preferably carries e gasket or peeking ring lo, although, this ie not neceesary, inasmuch as the flange 1,6 rnayseet directly Vz lgeinst the.extension,or nipple 5, elf

though in this case, the gasket 16 seats against the said extension or nipple, The sleeve 14;` is of a diameter somewhat smaller than that of the opening through' the extension or nipple 5, so as to provide an air passage leading from the atmosphere to the mixing chamber l.

A plugr 1'? is threaded into the lower end of the sleeve 14 and is provided with an upstanding conical tip'or extension 18 forming the valve adapted to seat Within the lower end ofthe duct or passage 10, the plug 17 being provided with. an annular series of passages or ducts 19, and with a depending rounded lug :2O between the ducts 19.

The sleeve 11i-'is spring pressed so as to ordinarily raise the sleeve to seat on the valves 18 and l5 and to this end, the spiral spring 21 surrounds the sleeve 1li- Within the yoke 6 and is disposed compressibly between the annulus 41 and the upper end of the sleeve 14. The lower convolution of the spring 21 is seated on the annulus the annulus being provided with an upstanding marginal ange 22 surrbunding the lower convolution of the spring, and. a nut 23 is threaded upon the upper end o the sleev, 'the upper convolution of the spring 21 being seated against the mit 23 and the nut being provided with an annular flange or lip Q4. engaging Within the upper convolution of the spring. By adjusting the nut 23, the ten,- lsion of the spring may be increased or dehrease'd, as desired to most effectively seat the valves 15 and 18.

llt is to be noted that the tube 9 provides a Water passage leading from the top 12 to the mixing chamber 1, and that the said tube also serves as a bearing for the sleeve 14 carrying the Water valve 18 andthe air valve 15.

ln use, it will be evident that the nozzle or spout 2 of the mixing chamber may be attaclied either directly or indirectly to the cylinder, the intake manifold or other part of an sinternal combustion engine, so that as the @fiston of the respective cylinder moves to draw in a new charge of carbureted gas, the suction Will extend to the mixing chamber 1. The suction created Within the mixing chamber 1 will draw the sleeve 14 down` Wardly or inwardly, thereby unseating the valves 18 and 15 simultaneously, so that Waterand air Will be permitted to flow into the mixing chamber. The air will How through the nipple 5 around the ange or valve 15, While the Water will iiow through the passage 10 and through the ducts 19 around the lug 20. The flow or" Water may be regulated by means of the needle valve 13, so that the supply 'may be proportioned :is desired, the'water and air being admitted into the mixing chamber 1 as specified servin;a to admix them thoroughly in order that 4they may be drawn through the nozzle or nipple to the cylinder. lhen the suction mines? is relieved, the spring 2l will again scat the valves 18 and 15 simultaneously, so .is to shut off the flow of water and air, it beingr observed that the present device is entirely automatic.

From the foregoing, taken in connection with the drawing, the advantages and capabilities of the present invention will be apparent, the benefits derived from introducing a thorough mixture of water and air into the cylinders of :in internal combustion engine being apparent to those versed in the art, and needing no lengthy description.
