ATTACHMENT non cARBURE moBs.

Application filed March 19, 1924. Serial No. 700,301.

This invention relates to an attachment for carburetors and 1s an improvement on my 'Patent Number 1,269,146, dated June 11,

1918, the object being to provide a carbu retor with means for delivering water, glycerine and air to the same for increasing the eiiiciency of the explosive charge produced thereby, whereby greater power will be obtained from the mixture.

Another and further object of the inven= tion is to provide an attachment'for a. carburetor which is provided with a sight feed indicator having a valve for controlling the supply of water and glycerine to-the explosive charge produced by the carburetor whereby the amount of glycerine and water admitted to the explosive charge can be regulated from the dash of the motor vehicle to which the device is attached.

A still further object of theinvention is to provide means for admitting a small proportion of the exhaust gases of the internal combustion engine to which the attachment is applied, to the explosive charge into which is introduced a small amount ofai'r' from the atmosphere to supply the necessary oxygen. Other and of the invention will be hereinafter set forth and the'novel features thereof defined by the appended claims. I a

In the drawings,

Figure 3 is a vertical sectionthrough the sight feed indicator and control; and

Figure 4 is a detail inverted section of the nipple for coni'iecting the pipe to the water jacket.

lathe drawing 1 indicates a body of 'a motor vehicle provided with an instrument board 2. Arranged within the body is an internal combustion engine 3 which is provided with an exhaust manifold 4,.intake manifold 5 and carburetor 6 which may be of any of the well known forms ofcarbu- I rotors now in use, the above description being given so that the application of my attachment can be readily understood. In the embodiment of the invention herein shown, I secure a. Y coupling 7 in the wall of the mixing chamber of the-carburetor below the throttle valve 8, the branches further objects and

advantages

9 and 10 of which are provided'with apertures 11 and 12 for admitting air into the fluid passing therethrough as will behereinafter fully described. While I have shown the Y coupling 7 installed in the mixing chamber below the throttle valve, Ido not 7 wish to limit myself to placing this coupling at thls exact point, as I am aware that it can be disposed in the intake manifold or 1n the carburetor-"above the throttle valve without departing from the spirit ofcmy in I vention.

Secured to the instrument boardc2 isa sight feed indicator 13 provided with an inlet 14 and an outlet 15 to which are conneeted

nipples

16 and 17. The sight feed indicator is provided with a plug 18 at its upper end forming a valve casing which is provided w1th a removable valve seat 19 in the form of a tube which extends down into, a glassv tube 20 of the indicator so that the passage of fluid through the tube 19 will be vislble from the drivers seat of the motor vehicle 7 Mounted within the plug 18 is a threaded valve stem 21 which is provided with a needle valve 22 at itslower end adapted to cooperate with the seat 19 for regulating the passage of fluidthrough the indicator or for completely cutting off the passage of fluid therethrough, the valve being provided with a wheel 23'at its upperend for manipulating the same.

v Secured in the nipple 16 of the indicator 'by coupling 24 is one end of a copper pipe 25}, the other end of which is secured toa n1pple26 by a coupling 27, said nipple 26 being tapped Into the water jacket of the internal combustion engine and is provided w1th a screen 35 for preventing foreign par ticles 1n the Water from being drawn throu h the same. Y a

'ljhe nipple 17 is providedwith a coupling 28 1n which is securedone end of a copper pipe 29, the other end of which is secured to the branch 9 of the Y7 by a coupling-30 By thisconStruction the water in the Water circulating system of the motor vehicle is.

drawn by the suction induced in the charge forming devlce through the sight feed indicator and delivered into the explosive charge, air being admittedat 11 so as to aerate the end of which is secured to a nipple 34, which is tapped into the exhaust manifold 4:, preferably back of the second cylinder of the internal combustion engine.

The exhaust gases are drawn by the suction of the engine cylinder through the pipe 32 and air is admitted atthe aperture 12 in the branch 10 of the Y 7 so as to reduce the temperature-of these exhaust ases to a C61 tain extent and to supply additional oxygen.

It will be noted that the Y 7 which is tapped into the carburetor is so connected to the water circulatingsystem and the exhaust gas manifold that the exhaust gases and water are firstsupplied with air from the atmosphere and then this exhaust gas and Water are mixed and delivered into the explosive charge so as to increase the moisture of the explosive charge, whereby the formation of carbon in the cylinders of the internal combustion engines will be reduced to a minimum. y

In order to supply an alcohol to the water which is delivered to the explosive charge, I place within the radiator or cooling system. of the internal combustion engine an alcohol, such'as glycerine or the like, which becomes thoroughly mingled with the water and is delivered with the water being drawn into the explosive charge by the suction of the engine into the cylinders of the engine with the explosive charge so as to moisten and supply glycerine to prevent the forma tion of carbon and to increase the eliiciency of the explosive charge.

As the amount of glycerine and water cleliver'ed to the explosive charge is small in comparison with the capacity of the cooling system of the internal combustion engine, the amount drawn from the cooling system does not in any way affect the eiiiciency of the cooling system of the internal combustion engine and I am able to produce an explosive charge for an internal combustion engine which will increase the mileage and produce a charge which has many advan- 'tages over the ordinary explosive charge now produced by a carburetor.

From the foregoing description it will be seen that I have provided a carburetor at tachment in whichwater and glyccrine are drawn into the explosive charge mixed with air and at the same time a portion of the products of combustion which are cooled by the admission of air from the atmosphere is delivered with the glycerine and water into the'explosive charge at such a'point that it thoroughly mingles with the explosive charge and produces an explosive charge of high eiiiciency.

What I claim is 2- 1. The combination with an internal combustion engine having a water cooling system containing water and glycerine, an exbureti-ng passage of the charge forming device, each branch of the Y being provided with an air inlet, means for supplying glycerine mixed with water from the cooling system of said internal combustion engine to one branch of the Y'coupling, and means for supplying exhaust gases to the other branch of said Y coupling "from the exhaust manifold of said internal combustion engine.

2. The combination with an internal combustion engine having a water cooling system, exhaust manifold, intake manifold vand charge forming device connected thereto, of a Y coupling in communication with the charge. forming device, means for supplying glycerine mixedwith water to said Y coupling from said water cooling system, means for supplying exhaust gases to said TY coupling, said Y coupling being provided with air inlets for supplying air to the fluid passing through said coupling and means for indicating the flowof water and glycerine to said coupling from said water cooling system.

3. The combination with an internal combustion engine having a water cooling system, exhaust manifold, intake manifold and charge forming device connected I thereto, said water cooling system being adapted "to contain water and glycerine, of'a Y coupling arranged in the charge forming device, each branch of the Y coupling being provided with an opening for admitting air thereto, means for supplying glycerine mixed with water from said cooling system to one branch of said Y coupling, means for supplying exhaust gases to the other branch of said Y coupling, means for indicating the flow of water and glycerine from said cool ing system to said coupling and means for controlling the supply of water and glycerine to said coupling.

4;. The combination with an internal combustion engine of a carburetor for producing an explosive charge for said engine, a coupling in communication with the mixing chamber of said carburetor provided with air inlets, means for delivering to said coupling a mixture of water and glycerine, means for delivering to said coupling exhaust gases produced by said engine, said exhaust gases and mixture of water and glycerine being mixed with air through the air inlets of said coupling before they are delivered to the mixing chamber of said coupling and means for controlling the volume of water and glycerine delivered to said coupling. v

In testimony whereof I hereunto aflix my signature.
