Specification of Letters Patent.

To all whom it may concern:

Be it known that I, DONALD J. ANGUS, a citizen of the United States, residing at Indianapolis, Marion county, and State of Indiana, have invented and discovered certain new and useful Improvements in Carbureters, of which the followingis a speciiication.

In `the operation of internal combustion engines on low-grade fuels, such as lowgrade oils, it is common practice to apply heat to the fuel for the purpose of Vaporizing it, or to aid in its vaporization. "An apparatus designed for this purpose forms the subject matter ofl my ap lication No. 103,261, filed June 12, 1916, this being referred to merely as a type of apparatus designed for this purpose, and not to,in any Way, have it understood as limiting my present invention to the construction of apparatus there shown.

In the use of such type of apparatus, it is` necessary to provide some means for starting v I have found, in practice, that volatile fuel, such as gasolene, may be used to advantage, and my present invention relates to a method and means for employing gasolene, 0r other volatile fuels, for starting the engine and operating it until a supply of heated or vaporized fuel'has been generate sucient to supply' the requirements Vof the engine, and to operate or aid in. operating the the engine.

engine whenever the heated or atomized fuel, becomes deficient to sup- M from any' cause, ply the requirements of the engine; and urther, to provide means whereby, when the supply of the heated oratomized fuel reaches a volume` sufficient to supply the engine, the volatile fuel may belautomatically cut oif, and again automatically supplied whenever the suppl of heated or atomized -fuel becomes de cient, all as will be hereinafte more fully described and claimed. y

Referring to the aompanying drawings, which are made a part hereo and on which similar reference characters indicate similar parts, i Figure 1 is a sectional view through a carburetor of 'special construction designed v to use a heated fuel, in the form of a vapor or liquid, its purpose being to supply the volatile fuel for starting the engine, and embody means for vshutting olf the supply "chamber 11.

fuel'is supplied when the heated fuel is supplied in suiiclent volume to operate the engine.

Fig. 2 a similar view illustrating a modied form,

Fig. 3 another similar view illustrating another modied form, and

Fig. 4 a'view `illustrating the form of ap paratus as shown in Fig. 1 applied toan engine with generator or vaporizer attached.

In said drawings, theportions marked 10 represent the casing of the carburet-er, 11 the' gasolene chamber, 12 the mixing chamber, 13 a valve forcontrolling the flow of the gasolene to the lmixing chamber, 14; a thermostat for operating said valve, 4:0 the engine, 41 the intake manifold, 42 the vaporizer, and 43 the exhaust pipe.

A general description of the apparatus will describe its construction and define i the invention, the structure of the parts themselves being largely of common and well known types.

Referring to the form shown in Fig. l1. The supply of gasolene in chamber 11 is regulated by a valve 15 controlled by a float 16 in the usual and well known manner. The atomizer nozzle 17 projects into the mixing Vchamber 12 and itsoutlet is controlled by a valve 13. The air inlet is controlled by valve 18 on a stem 19, which also `carries a valve 2() controlling theport between the mixing chamber and the fuel chamber 21, which is adapted to beconnected `with the heatedffuel supply by means of a screwthreaded neck piece 22 adapted to be connected with the heated fuel'supply pipe 45.

The valve 13 is mounted on a support 14 of a material on its lower side adapted to be readily expanded by the heat of the fuel, causing the support to turn u wardl seat the valve 13, and shut off t e supply of volatile fuel.

y and It will thus be seen that the chamber 21 is connected to the heated pipe 45. The engine is manner by means' of the volatile fuel in As soon as sufficient heated fuel supply, as by valve 13 will be closed, the supply of volatile fuel shut off and the en V its supply of fuel from chamber 21, the suction causing valves 18 and 20 to intermitto heat the support'14,.

started 1n the usual l flexible diaphragmv 31,

tcntly open for admitting the airand the fuel to said mixing chamber. Should the supply of heated 'fuel become deficient, support 14 will cool and the support vwill cause valve 13 to fall and allow volatile fuel to be supplied in the regular way, or until sufficient heated fuel is available to again supply the needs of the engine. Heat from thequantity of fuel then coming into the chamber 21 will automatically close valve 13, and the engine will run on the fuel coming from the heater.

The structure shown in Fig. 2 is substantially the Same as that shown in Fig. l, except that the valve 30 for controlling the flow of the volatile fuel is operated by a actuated by the pressure of the heated fuel; otherwise the operation is the same as that of the construction illustrated in Fig. 1. In the construction shown in Fig. 3, the valve 32 for controlling the flow of volatile fuel to the mixing chamber is connected through a bell-crank lever 33 and connecting` rod 34 to an operating device. (not shown) on the dash or convenient to the driver.

Fig. 4, as will be readily seen, shows lan apparatus wherein the vaporizer or generator forming the subject matter of my application above mentioned is combined with the particular carbureter shown in Fig. l to supply fuel to the engine. The heat is supplied to the vaporizer 42 by exhaust gases coming through pipe 43 `and passing out by pipe 44 while the vapor or heated fuel passes to chamber 21 by the pipe 45.

It will be understood, however, that the particular type of heater, or vaporizer, or carbureter, 1s not essential, but that my invention contemplates any form of either that will provide means whereby a volatile fuel is supplied by the absence, or deficiency in supply, of heated fuel, and cut ofi by a S11-fliciency inthe supply of said heated fuel.

cooling of said Having thus fully described my said invention, what I claim las new, and desire to secure b Letters Patent, is:

1.. A car ureter for internal combustion engines, comprising a Casin roviding a mixing chamber, 'a liquid fue c amber, and a chamber adapted to receive heated gaseous fuel, means for projecting liquid fuel into the mixing chamber in the form of spray, a thermostatic control for said spraying means located in the chamber for the heated gaseous fuel, a valve controlling the admission of air into the mixing chamber and operable through the suction of the engine, and a valve controlling the admission of the heated gaseous fuel into the mixing chamber, said last named valve connected to and operated by the air intake controlling valve, substantially as set forth.

2. The combination with an internal combustion engine of a. carbureter therefor comprising a casing providing a mixing chamber, a liquid fuel chamber, and a chamber adapted to receive heated gaseous fuel, means for projecting liquid fuel into the mixing chamber in the form of s ray, a thermostatic control therefor located in the chamber for receiving the heated gaseous fuel, a common control. for regulating the admission of air and the heated gaseous fuel into the mixing chamber, a fuel vaporizer connected to receive theheated exhaust gases from the engine, and a communication between said vaporizer and the chamber for heated gases in the casing, Substantially as set forth.

In witness whereof I have hereunto set my hand and .seal at Indianapolis, Indiana, this 24th day of July, A. D. nineteen hundred andaixteen.
