Specification of Letters Patent.

Application filed ctober 24, 1908. Serial No. l159,361.

To all whom' tf/nay concern.'

Be it known that I, CHESTER CHARLES J ONES, a citizen of the United States, residing at Beatrice, in the county of Gage and State of Nebraska, have invented a new and useful VGrasolene-Engine, of which the following is a specification.

`.My `invention relates to internal combustion engines, as4 gas and gasolene engines; and the objects of my invention are to produce an engine having'a superior method of compressing and retaining the explosive charge, and also a superior method of interi'o'r coolinO these results by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical section, showing the at one extremity of its stroke. Fig. 2 is a like vertical section, showing the piston at the other extremity of itsstroke. Fig. 3 is asection on the line 3 8 of- Fig. 1. Fig. L1 is a section on the line 4-4 or' Fig. l-. Fig. 5 is a section on the line 5-5 of Fig. 1, and Fig. Gis a section on the line (3*6 of Fig. 1.

vSimilar figures refer to similar throughoutwthe several views.

My device, as here illustrated, is a gasothe two cycle type and referring to the drawings may be described as followszel i 1 is the cranlccase, and v V the engine shaft of the engine. #L

4 is the crank pin and .l rod, having a wrist-pin 21. i

S is atwo-part piston, hai/ing compression rings 9 on its upper piston head 11.

10 is an auxiliary piston, formed integral with the upper piston-head, and is provided with compression rings 12. It acts as a plunger as hereinafter described. Surrounding the piston is a eylinder 6, provided at one end, for a portion of its length with a raised interior wall 7, forming a lower interior compression cham ber 14 within the cylinder. I

13, 13, are cooling ribs upon the interior sur ace of the piston, having channels 15 between the'ribs through and over which air or other cooling Huid may be forced as hereinafter set forth.

16 is a port in the byepass 17, in the wall 18 is the upper port parts the connecting piston opening to the of the cylinder. and 19 the lower port `the suction stroke, for the engine. I achieve' of the 1oy-pass 1.7 22 is the 'spark-plug openlng. i

19 is anlexhaust port,'and 2O an intake port,-both through the walls of the cylinder.

It will be observed that`the lower and auxiliary piston 10, is provided with compression rings 12, the Same as the piston head 11; but the walls 7 of its cylinder are contracted so as to allow the upper piston to telescope them, on its downward stroke, thus compressing the gases which have been taken into the chamber at ,the intake port 20 by and holding them compressed in the compression chamber 14 until the port 16 opening in the wall of the piston meets the lower port 19 of the by-pass when they are allowed to enter the cylinder above the piston through the upper port 18 of the by-pass 17.

In orderto reach the by-pass the compressed gases must pass around one side of the piston across the piston-head 10 and halfway down on the other side to the opening 16, in the wall of the piston.

The piston has a partition 111 with an opening only on the opposite side from t-he port-opening 16. y This forces the mixture of gas and air by the route described and it will be observed that the annular conipression chamber .is entirely closed below the inlet port 20 so that thegas canne escape therefromv and the compression will be thorough.

' Formed on the interior oi the piston, preferably longitudinally thereof, are coolingribs '13 and channels 15 between `the ribs for the passage of acooling Huid, as air, or air and gas.` ln operation every impulse throws the fresh air and gas around the inner walls of the piston with such velocity that the piston is cooled.

lVhat I claim and desire to secure by Let.- ters Patent of the United States is hydrocarbon engine comprising Icon# centric cylinders forming an annular compression chamber closed except at its upper end, an intake in the outer cylinder above the upper end of the inner cylinder, an exhaust in the side of the outer cylinder. a bypass disposed longitudinally on the side of the outer cylinder with its ends between the planes of the intake and the exhaust, concentric pistons arranged within the cylinders,

' the upper end of the outer piston being above and spaced from the upper end of the inner In testimony that I claim the foregoing as piston., and a transverse partition eonnecting my own, I have hereto affixed my signature the upper end of the inner piston with that in the presence of two Wltnesses.
