APPARATUS FOR MIXNG AND CGNTROLLING- A SUPILY 0F hlll'EL FOR EXLOSON- ENGXNES.

Application filed October' 8, 1918. Serial No. 257,404.

all speeds the maximum temperature and efficiency of engines of the internal combustion type, and also means whereby thecarbon willbe converted into a combustib-le gas and consumed, with the result that there will be no accumulation of carbon in the cylinders and the efficiency of the engine will he greatly increased, whereby the amount of work or mileage for a given quantity of gas or-fuel will he materially increased, and

with the further result that no obnoxious gases will be discharged from the exhaust. A further object is to provide improved means which may be readily attached to the radiator of any of the present manufactured motor vehicles. Y A further object is to provide an improved apparatus of this character which will be simple, durable and cheap in construction, compact in arrangement, easily installed, and effective and efficient in operation.

To the attainment of these ends and the accomplishment of other new and useful olojects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrange ment of the several' parts, hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention, and in which Figure 1 is a view partly in elevation and partly in section. and with parts broken away of an automobile, having an attachment applied thereto, constructed in accordance with the principles of this inven- I' tion.

F 2 is a top plan view' of a portion of the apparatus shown in Fig. 1. ln the drawings, the apparatus has been shown as being applied to an automobile, but it is to be understood that. it may be applied and used for other purposes, and

therefore, it is desired that the drawings herewith lsubmitted shall' hel considered as being merely diagramma-tic.

lReferring more particularly to the drawings,vtlie numeral l0 designates yan engine cylinder having the usual intake manifold 11 and the exhaust manifold 12, a

The usualradiator 13 may be supplied titl with an roverflow pipe 14, although such overow is not necessary with the present" invention. The radiator contains a supply of water which may, if desired, have mixed therewith kerosene or other hydro-carbon or combustible fluids. A pipe 15 has communication with the interior of the radiator 13, and the' inlet end 1G of this pipe is disposed at a point above the water level of the radiator. Thepipe may be of any desired size, and maybe either coiled about they exhaust manifold 12 as at 17, or a portion of the pipe may be held in contact with the exhaust manifold in any suitable manner. of vthis pipe 15 has communication with a suitable valve structure 19.0f any desired type. This valve is adapted to control the mixturewhich is supplied from the .radiator The other end '18 13 t0 the engine," and may be operated in i the radiator to the engine will he increased,

and when the valve is closed, the supply of mixture from the radiator to the engine will be cut ofhwith Athe result that when the supply of mixture from the radiator is increased,`the supply of fuel from the carbureter 21 is diminished, and vice versa.

ln order to supply outside air to the radi ator 13 to replace the vapor drawn from the radiator, and to prevent the formation of a vacuum, and to regulate the mixture that is drawn from the radiator, and also to provide an improved apparatus which may be readily attached to-any radiator of this 'type now being manufactured, the apparatus is constructed as hereinafter described.

It is to be understood, however, that the ap embodies a cylindrical body pertion 22 cfa suitable size and of a diameter in cross section slightly larger than the diameter of the fill opening 23 of the radiator 13, and is open at both the top and bottom, so that the bottom may be telesco'ped:l over the flange of the fill opening and then secured in position 4in any suitable manner, such as by means of fastening devices 24C.

Within the body Vportion 22 and above the diameter thereof to extend thereacross, is a partition 25 having one or more openings 26 therethrough, forming communication between the chamber 27 and the interior of the radiator 13, and which opening or openings 26l are adapted to be. closed byfmeans of a suitable float valve 28a to prevent any of the liquid from the radiator 13 from splashing into the chamber 27 within the body portion 22. The float 28a will, as the level of the liquid in the radiator lowers, drop to uncover the openings 26 so that vapor may pass from the radiator into the chamber 27.

The inlet end 16 of the pipe 15 passes through the partition 25 from the bottom thereof and terminates in the chamber 27 at any desired point above the partition, and the passage of the mixture from the chambe'r 27 through this pipe 15 to the engine will be controlled by the actuation of the valve 19 and the suction in the engine cylf inder.

The chamber 27 is closed by a closue 28 having a flange 29 which telescopes with the body portion 22, and is secured against accidental removal in any suitable manner such as by means of fastening devices or catches 30.

The closure 28 is provided with openings 31-32 and the closure supports two depending pipes we which extend 'finto the chamber 27 and communicate with the respective openings 31-32. The pipe 33 terminates within the chamber 27 and above the piTilOll 25, While the pipe 34 extends loosely through an opening in the partition 25 and terminates in the radiator above the high water `line therein, so that when the closure 28 is removed, both of the pipes -Sl will be removed therewith.

Thus it `will be seen that the pipes S31- 34: have communication with the atmosphere, and in order to control the admission of atmosphere into these pipes, any suitable mechanism may be provided, such, for instance, as the valves or covers S35-36, pivotally connected with the closure 2S and adapted 'to'be moved over the respective openings. These valves may be operated in any suitable manner from a point convenient to the operator by means of fiexible rods 37-38- If desired, the valves 35 36 may be adjusted and held in a fixed position.

ln assembling, the pipe 15 may be secured in position in any suitable manner at the point where it passes through the radiator wall, such as by means of any ordinary and well-known coupling designated generally by the reference numeral 39. The lower end of the pipe 34 may be allowed to remain open, or if found necessary, a float valve similar 'to the float valve 2S may provided, to automatically close and open the said end.

By the use of this improvement, it renders possible the use of two kinds of fuel oil, that is gasolene and a heavier oil.

Tt is sometimes found desirable 'to start the engine on gasolene until the engine reaches the proper temperature and condi-- tion, and then shift to a heavier and less expensive fuel, then just before completing the trip or just before leaving the engine to stand for a while to become cooled off, the heavier oil is cut olf and l'he gasolene is employed in the engine, so that on the next running of the engine it will be in a better condition to start with a lighter fuel in the carbureter.

This may be accomplished by providing two supply pipes LlO--ll leading from the respective supplies of the two fuels and both' connected and communicating with the carbureter 21 by means of a suitable connection Ll2. These pipes may be respectively controlled by suitable valves 43-44 located in aconvenient position for the operator.

Obviously, the supplies of fuel are controlled by operating the respective valves 113-44.

It is thought that the operation of this improved apparatus will be clearly understood from the foregoing specification, but, briefly stated, it is as follows:

Assuming that the supply of gasolene is open to the carbureter and the supply of heavier. oil is closed to the carbureter, the

valve 19 is opened and the valve 36 is opened to admit outside air through the pipe 34 into the radiator. As the engine operates, the suction therein will draw vapor from the chamber 27 through the pipe` 16 and the vapor in the lradiator will pass through the openings 2G |into the chamber 27. The valve 35 is then opened to admit outside air into the chamber 27 through the pipe 33 in whatever proportion it is desired, or to meet the existing and best conditions. This will result in reducing considerably the amount of gasolene ordinarily used under similar conditions, at least one-half, because for every gallon of gasolene employed in the engine, an equal amount of water and an additiow ally large quantity of air is also utilized.

Vhen it is desired-to use a heavier and less expensive oil, all-that is necessary is to start the engine on the gasolene and then at the proper time shut off the gasolene supply and open the other oil supply.

Olwiously, the valves S5-5G may also be ladj-ustedilto IIiieetl-'the conditions `With the @rangement f' use of a heavier oil, besides reducing the ex- A`ter amount of power is obtained .carbon isicoiisumecl'l and not wasted. e'slilt ,Affurtlieryinthe fact that the andispafrk plugs are kept clean of 'd tpe-"necessity Vvof grinding the i a" v seats is practically eliinit the parts has herein been vcribed, it is to be understood tliat'fvaiiou haiiges may be made in the lisfjit 7oilstriifction and in the combination'fandariaiigeihent of the several parts vai-anla.:
