JOHN c. FREDRIGKSEN, or MILLER, INDIANA.
' INTERNAL-COMBUSTION ENGINE.
T 0 all whom it may concern Be it known that 1, JOHN C. F REDRIGLK- snN, a citizen of the United States, and a resident or the city of Miller, county of Lake, and State of Indiana, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the ton 2 operating therein and connected by a e connecting rod 3 with the crank shaft at thereof.
An intake passage is formedin the head of cylinder 1 and is controlled by suction operating intake valves 6 as indicated. a suitable spark plug 7 being also provided in the head of said cylinder. Transversely aligning valve cylinders 8 and 9 are arranged in the walls of cylinder 1 and pisstons 10 and 11 are arranged to operate therein. The pistons 10 and 11 are mounted on a piston 13 operating in.a dash pot cylinder 14 arranged at one side of cylinder 1 and provided at each end with minute air escape ports or openings 15 for cushioning the movement of the pistons 10 and 11 in each direction.
A movable plug 9' is also provided for giving access to cylinders 9 and 8. An ex haust port 16 leads to the outer end of cylinder 8. the walls of which are also provided with slots 17 acting also as exhaust ports controlled by piston 10 to permit exhaust of cylinder 1. The inner end of cylinder 1 is provided with a piston controlled port 19 located at the inner end of the stroke of piston 2 and whereby at the inner end of the stroke of said piston, the combustion pressure remaining in cylinder 1 is admitted to the outer end of cylinder 8 to operate piston 10 to open the exhaust through ports 17 Sp fic i of Lctterslatent Patented Feb. 14, 1922.

and 16, the combustion pressure on the inner faces the pistons 10 and 11, being opposite and balanced.
A passage 20 in the wall of cylinder 1 leads to a port 21, as indicated, arranged to co-ope'r-ate with by-pas's passages 22 and 23 positioned in the walls of piston 2. An annular air compressing cylinder or space 24 is formed in the inner portion of the walls of cylinder 1 and an annular air compresspiston head 25 on piston 2 operates therein as shown. Air ports 26 are arranged centrally in the walls of cylinder 24, establishing free communication with the atmosphere. By this means and arrangement, at the inner end of each stroke of the piston 2, the cylinder 9 is exhausted into cylinder 2 1 by bypass 22 to permit the opening of piston 1.0 for the exhaust as explained above. On the reverse movement of piston 2, after port 26 is passed, air is'compres sed in cylinder 2t-which is admitted by by-pass 23 into port 21 and passage 20, and consequently into cylinder 9 to close the exhaust ports 16-47. On the intake and the compression stroke of piston 2, valve 10 is unaffected by the conditions in cylinder 1 as will be'readily understood.
'The arrangements set forth constitutes a simple, automatic, positive and etlicient means for controlling and effecting the complete exhaust of the engine cylinder.
While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is cap-ableof variation and modification without departing from the spirit of the invention. I therefore, do not wish to be limited to the precise details or construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
Having described my invention, what I claim as new and desire to secure by Letters Patent is 1. An internal combustion engine, co1nprising an engine cylinder and areciprocating engine piston operating therein; transversely alining valve cylinders in the walls of and projecting into said engine cylinder, there being an exhaust port connected with the outer end of one of said valve cylinders, and there being exhaust ports in the walls of said one-valve cylinder; valve pistons operating in said valve cylinders; a piston rod connecting said valve pistons; and a port and passage in the wall of said engine cylinder, controlled by the engine piston and communicating with the outer end of said one-valve cylinder; for closing said one-valve cylinder, substantially as described.
2. An internal combustion engine comprising a cylinder; a reciprocatory piston exhaust valve therefor; a piston controlled port for utilizing the combustion pressure of said cylinder for moving said exhaust valve to open said valve; and means on the cylinder piston for compressing and utilizing air to move said valve in the opposite direction to close the same, substantially as described.
An internal combustion engine comprising a cylinder and a reciprocating piston operating in said cylinder; a suction controlled intake for said cylinder; transversely aligning valve cylinders in the walls of said engine cylinder, there being an exhaust port connected with the outer end of one of said valve cylinders; exhaust ports in the Wall of said valve cylinders; pistons operating in said valve cylinders; a-pist0n rod connecting said valve pistons; a dash pot operating on said piston rod; a piston controlled port and passage in the wall of said engine cylinder communicating with the outer end of the valve cylinder provided with the ex 'haust ports; and means controlled by the engine piston for periodically compressing and admitting compressed air to the other valve cylinder for closing the exhaust, substantially as described. 3
4. An internal combustion engine comprising a cylinder and a reciprocating piston operating in said cylinder; a suction .con-
and automatic means said engine cylinder communicating with,
the outer end of the valve cylinder provided with the exhaust ports an annular air compressing piston at the inner end of the engine piston, there being an annular air compressing cylinder located in thecwalls of the engine cylinder co-operating with said air compressing piston, and having a central port communicating with the atmosphere; a port and a passage in the Wall of said engine cylinder connecting the outer end of the valve cylinder opposite the one provided with the exhaust ports with a point in the wall of said engine cylinder closely adjal cent the outer end o'fsaid air compressing cylinder; and bypass passages in the walls of said engine piston arranged to throw said last mentioned port into communication with said air compressing cylinder at opposite ends of the stroke of said engine piston, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of the subscribing witnesses.
