Description

ously with the sucking in of the air, fuel will be drawn, in like manner, through the chamber 20, pipe 22, and inlet port 2l. of the carbureter to the mixing chamber 26 and mixed in proper proportions with the air. The mixture Will then be sucked by the engine through the conductor 3 into the explosion chamber of said engine;

As said air and fuel pass through their respective casings they willl contact With the heated Walls thereof' andv absorb heat from the conductor l heated by exhaust gases from the engine. The preheating of the fuel greatly assists the Vvaporizing thereof Within the mixing chamber of the carbureter and the preheating of the air effects amore perfect mixture of the vaporized fuel With said air in the carbureter.

j After being mixed the charge passes from the carbureter through the conductor 3 and is again heated at this point before entering the engine, said conductor 3 being heated by the products of combustion as they pass through the conductor 1',.consequently when the heated charge enters the combustion chamber it Willbe in a moreperfect condition to be ired than is usually the case in internal combustion engines and practically all of the carbon will be consumed instead.

of being deposited upon the inner walls, ports and valves ofthe combustion chamber.

Furthermore, owing to this preheating of the elements which compose the charge, before they are mixedand of the mixture, prior to its being admitted to the engine, kerosene and other loW grades of oil may be utilized asfuel, and all danger of carbonizing the engine Will-be practically eliminated.

The portions of the conductor l that are lseparated by the enlargement 2 are identical in size and shape and the air casing 9 and fuel receptacle 18 are interchangeable thereon; Furthermore said casings may each be rotated upon the conductor l to locate the

discharge orifice

1,5 of the air casing'and the inlet and discharge ports of the fuel receptacle to meet varying piping conditions found in different types of-engines.

'Having thus specifically described `my invention Whatl claim and desire'by Letters Patent to secure is:

l. A device of the class described having, in combination, an exhaust tube, having a centra] enlarged portion `integral therewith, a casing, detachably mounted upon and surroundingsaid exhaust tube at each side of said enlarged-portion, a carbureter, means l for providing communication between one of said casingsland the'fuelinlet of said car- ,bureter, and means for providing communi- ,l cation between the other casing and the air -vinlet of said carburetor, each of said casings gbeing interchangeable at each side of the enlarged portion. Y l

2. A device of the class described having7 in combination a. conductor for the heating medium, having a central enlarged portion and two oppositely disposed members integral-therewith, a fuel casing rotatably mounted upon and detachably secured to said conductor, an air casing rotatably mounted upon and detachably secured to said conductor, each 'of said casings entirely surroundingsaid conductor and being interchangeable thereon, means constructed and arranged to mix the air and fuel from said casings, and means for conducting the mixture from said mixing means through said conductor.

3. A device of the class described having, in combinatiom'a conductor for the heating medium comprising a centrally disposed enlarged portion and members integral with and extending laterally from said enlarged portion in opposite directions, a casing surrounding each of said laterally extending members adapted to respectively contain fuel and air, and also adapted to be interchangeable upon said laterally extending member, means for mixing said fue] and air, and means for conveying the mixture without 0pposition through said conductor, in a direction substantially at right angles to that of said medium.

4L. A device of the classdescribed having7 in combination, a conductor, an enlarged portion arranged intermediate of the ends of said conductor, an airl casing detachably mounted upon andl surrounding said 'conductor adjacent to one side of saidA enlarged portion,` a fuel casing detachably mounted upon and surrounding said conductor l adjacent to the opposite side of said enlarged portion, said air casing and vsaid fuel casing being interchangeable'upon said conductor, a carbureter, means connecting said airV casing and said fuel casing with said carbureter, and means for conducting a chargefrom said carbureter through said enlarged portion.k

6. A device of the class described having,

in combination, la conductor forthe heating medium,: including an enlarged portion formed integral with said conductor intermediate of the ends thereof, an air casing surrounding anddetachably secured to said i conductor adjacent to andat `one side of said enlarged portion, a fuel receptacle surroundingand detachably secured to said conductor adjacent to-the other side 0f said enlarged portion, said air casing and said fuel receptacle cach being rotatable and interchangeable upon saidconductor, a mixing device connected irespectivelyivith said fuel receptacle and said air casing, and a second conductor connected with said mixing device .1'25

and extending transversely of said first conductor through said enlarged portion adapted to heat said mixture. l

6. A. device vofthe class describedhaving,

in combination, a cylindrical conductor provided with an enlarged portion integral therewith intermediate the ends thereof, a.

receptacle surrounding and detachably secured to said cylindrical conductor, means for securing said receptacle to said conductor, an air casing surrounding and detachably secured to said cylindrical conductor and provided with a plurality of air inlet ports, means for securing said air n casing to said cylindrical conductor, said fuel receptacle and'Said air casingbeing interchangeable upon said cylindrical conductor, a carbureter having communication I with said tube, and means for connecting i said fuel receptacle and said air casing Wlthv said carbureter.

In testimony whereof rI have hereunto set vmy hand in presence of two subscribing Wit-v nesses. Y
