To all whom t may concern lle 1t known that l, CHARLES YV. HART, a

-citizen of the United States, residing at Charles City, county 'of Floyd, and State of lona, have invented new and useful lmprcveinents in .Carburcters, of which the toly lowing is a speciiication.

My invention relates to improvements in ca rbureters.

rlhe object ofi'iny invention is to provide l'iydrogen to combine Vwith the carbon.

ln the following description, reference is had to 'the accompanying dra-wings, in which-- f Figure l carburetor, partially broken away on the line fue Fig. 3 to .show the by passes. Fig. is a sectional view, drawn on line y of Fini. l, showing one of the iioat rs with its valves and the by pass pertaining thereto. Fig. 3 is a sectional View, drawn on line i12-Y of Fig. l.

Lilie parts are 'identified by the same reference characters 'throughout the several viewsa Briefly stated, the siniplest and l believe, the best means for carrying out niy newly invented method consists in subdividing the is plan vieu7 of my improved air in a carburetor, and directing one of the.

currents into the pathof a supply of liquid hydro-carbon to vaporize andl atomize the latter, in the desired quantity, another cui'i rent being at the saine time directed into the path. oi a supply of water to-likevvise vaporize or atoniize the required quantity, and then re-uniting mixing the tvvo currents, preparatory to the ignition of the mixture inr the cylinder o 'i an internal conibustion engine, either with or witl'ieut an additional supply oli-fresh air'ivhich will be admitted to excessively charged niixturei'i. By subdividing the air currents and mixing each directly with one of the liquids, the

i relative proportions of each liouidjto the air can be inaintaincdin such a ratio that the quality of the mixture delivered tothe engine may be kept substantially at the right proportions by the admission ofireshv air through a spring` actuated regulating valve, whenever thev suction becomes `so great kas to have a tendency to overcharge the vapor with the liquids or liquid products. y

lleiierringto the drauf'ings, a valvecasing l is provided with a passage 2, controlled and, normally closed by a spring actuatedy valve 3. .iir is admitted 'to the inlet cavity Ll througlra duct 5 and the valve 3 being closed, a portion of thc` air passes to the outlet cavity G, through a by pass?, haing a.

the admispreferably by 'a Another portion olf the air port S for liquid hydrocarbon, sion of which is controlled needle valve tl.

is delivered from the inlet cavity through aby pass l0, which is provided with a similar water inlet port, controlled, preferably by needle valve l2, rlhe ltwo currents are united and mixed 'in the outlet cavity 6 and dclii'cred to the engine cylinder through duct lilhenever the suction is excessive, the 'valve opens against the tension of spring il and delivers an additional quantity of iii-eeh air directly 'from the inlet to the out let cavity, thus diluting the charge, Which would otherwise contain of liquid in such cases, and also relieving the suction in the by passes.

For light loads, no Water is required, and the arrangement is therefore such that it requires a greater degree of suction to draw the water, than to draw the oil'. Thegreater specilic z(gravity ot' the Water alone tends to prevent its delivery when the suction is light, but it will ordinarily be found advisable t0 alsoniaintain the water supply at a son1ewhat lowerlevel than that of the oil. "Water and oil cavities G and 17 respectively are preferably provided, and the feed through their. inlet ducts 18' and 19 controlled'by i valves 2l operated by floatsil to maintain il a constant level, with suction ducts 23 leading tothe ports 8 and ll troni the oil and Water cavities respectively. The valves and .floats in the oil cavity are the saine as those -in 'the lWater cavity, the only di"`rference bean excessive supply- .iii

5 troduce Water vaporor steam in to a carbureter for the purpose of facilitating comibustion, but I have found that by introducing it in liquid form and causing its evaporation Within the cylinder, consider able additional pressure will be developed, and at a lower temperature, since the Water Will absorb a large number of heat units which become latent with vaporization. The quantity of Water introduced can also be regulated to suit the requirements of all the varying conditions met in practice, and it is highly essential that means be provided which Will adequately maintain the correct proportions of the introduced lwater to the supply of hydro-carbon and air which make up the balance of the charge. By dividing the incoming air and separately charging one portion with Water and another portion with hydro-carbon, I am enabled to avoid l any interference by the vapor absorbed from one of the liquids with the absorption ofl vapor by the air from the other liquid, and I, therefore, believe that I am the iirst to provide for the intrc duction ofiwater and of hydro-carbon vapor into the air in proper quantity and in the proportions required for thc variable charges of explosive mixturer delivered to internal combustion engines, since I have not found it practical to introduce both vwater and hydro-carbon into the same body of air and secure the proper proportions of both by so doing.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A carbureter provided with a mixing chamber, an air inlet, three passages between said inlet and mixing chamber, means for admitting liquid fuel to one of said passages, means for admitting Water to another of said passages, and means for resilienty controllingfthe passage of a diluting charge-5f air through the third and central passage.

In testimony whereof I allix my signuture in the presence of two witnesses.
