Patented Mar. 18, 1930 UNITED STATES JOHN BABLETTA, OF GALT, CALIFORNIA COMBUSTION ENGINE 'Application filed August 27, 1923. Serial No. 659,605.

One of the objects of my present invention is to provide a combustion engine with simple means for self-ignition, when using crude oil as fuel.

Another object of the invention is to provide simple means for making a two cycle engine adaptable to speed variation without misfiring.

To the attainment of the foregoing, the invention consists of improvements which are hereinafter described and definitely claimed. j

The accompanying drawings show the improvements in the combustion engine, but I believe that the said drawings are sufiicient to make clear the invention in which a reference numeral is applied to designate the same part throughout, but I am aware there may be modifications thereof. 20'

Figure I is a'transverse sectional view of the engine showing the interior mechanism. Figure II is a sectional View of the auxiliary cylinder showing the piston,'the'eccentric gears for driving the piston at high speed and the air passageways.

In Figure 1, number 3 is the combustion cylinder, 4 the enlargement of cylinder 3 forming a larger air cylinder for the scavenging cylinder 3, 5' the air tight crankcase,

50 the cylinder head, 6 the combustion piston, 51 the rings, 7 the enlargement of piston 6 to fit the air cylinder 4, 52 the rings adapted to create a low compression in the crankcase 5, 8 the projection slide extending from a portion of .piston 7 with the port opening 10 to transmit air to one of the air passageways at the time it registers with 17 and 18. The port 49 opens the upper end'of the air cylinder 4 free to the atmosphere and releases it from compression at all times, 9 is a spring bearing down on slide 28 which maintains the projection slide 8 and piston 6 and 7 in an air tight position over the air passageways entrances, 12 the throttle valve to regulate air through the pure air passageway 18 and 11 a similar valve to regulate air through the carburetor passageway 17 In Figure II, the throttle valves 11 and 12 are opened or closed simultaneously by the hand lever 45 which is connected to said valves by the two valve levers 54 and 55 fastened rigidly to the valve stems at 59 and 60 at one end and joined by pins 61 and 57 to the adjustable connecting link rod 44 by their other ends and forming a movable joint thereby, then the connecting rod 46 is connected to the valve leversby pin 57 at 62 at one end and by pin 58 in the hand lever by the other end, pin 68 is the b'earing'for the hand lever 45 and 64 the adjustable stop screw, 44 is the adjustable connecting link rod adapted to adjust the relation of said valves to each other and their combined relation to said passageway; 54 is an adjustable valve lever adapted to be so adjusted by lengthening or shortening as to provide a quicker or slowerjopening or closing time to valve 12 even though both valvesare moved 7 simultaneously by the hand lever 45.

In Figure I, 13' is the air inlet port to crank case 5, 14 the air inlet pipe, 15 the exhaust port and pipe, 23 the exhaust discharge heat port leading through pipe 47 and through coil and discharging at 24 to heat the fuel oil in the carburetor, 19 is the secondary air passageways for equalizing theair pressure i in the carburetor float chamber 21 to that of the carburetor air passageways 17, 20 the fuel inlet to carburetor, 21 the carburetor float chamber, 53 the needlevalve opening for fuelizing the air, 22 needle valve to regulate N the fuel quantity, 26 a screen to mix up-the fuel and airtraveling through passageway 17 v 27 and an electric coil 27 to heat the fuel in the carburetor needle valve 53 for starting.

29 is the pistonpin, 30 the connecting rod,

31 thecrankshaft to 'reciprocatepiston-6 and 7, v62 the crank shaft pin. 7
