GAS-ENGINE.

Specification of Letters Patent.-

Patented July 2,1912.

Application filed May 11, 1908. Serial No. 32,167;

To all whom it may concern: Be it known that I, GEORGE E. Cams, :1. citizenof the United States, residing at Detroit,'county of lVayne, State of Michigan, have invented a certain new and useful Im provement in GasEngines, and declare the following to be a full, clear, and exact del scription of the same, such as will enable tively converted into available energy. -I

accomplish these objects in the device illustrated in the accompanying-drawings, in which the figure is a sectional elevation of a four cycle engine embodying my invention.

A, is the cylinder, and B the crank case.

C is the piston adapted to reciprocate in the cylinder A.

D is thewxhaust, and E the inlet valve.

F is a connecting rod joining the crank G and piston C.

H is a passage through which air is forced into the cylinder A, above the piston.

I, is the port leading from the passage H to the cylinder A.

J, is a pocket or chamber formed in the piston C. p

.N is a non-return valve controllingr the entrance into the crank case.-

A plate K constitutes a deflector located at right angles to the axis of the cylinder partially covers the chamber J in the piston leaving an opening L from said chamber engine.

.into t-hecylinder above the piston, andan opening M adapted to register with theport I at-the lower end of the stroke of the piston.

The operation of the valves E and D is the same as in the ordinary four cycle When the piston C rises, it sucks in atmospheric air past the valve N, andwhen the piston descends it compresses such air in the crank case B, and when the opening M registers with the port I, the com resse air in the crank case B is disc arged through the passage H, port I, opening M, chamber J, and passage or opening L, into the cylinder A above the piston C; thus the ton O, and when this is fired the chamber J is filled with air andthe cyliir der above the piston with an explosive mix ture. When presses the'explosive mixture above the pisrises suddenly and is cushioned by the m.

the shock of the explosion is a quick expansion of the ignited charge poi!- mitted, thus diminishing the dissociating effect, and moreeffectively storing the. piston C rises it'coin- '60 pressure siliency of the air in the chamber J, so that I diminished, and i orgy of-the explosion to be given outas the piston is forced'downward.

n will be observed that there m twp- I arate. sources ofsupply to the cylinder; In

stead of having one suppiya combustible mixture and the other an mcombustible gas,

I may use a rehdily'inflammable mix supplied through One channel and a less inflammable mixture through the other. For

example, air and asolene vapor may be taken in through 1% and .air and kerosene through N. In such case the. more inflam mable and quicker acting mixture may be first ignited and the flame may be communicated to the second mixture throughfthe.

burning of the first.

Referring to the figur'e, it will be noticed that there is an intake from the crank champ ber discharging the roducts of combustion" and filling the cylin er with air, or combustible mixture'if a combustible mixture is drawn through the valve N insteadof pure air, then there is an intake through the valve E of a combustible mixture, then there is an intake again from the crank case raising the pressure in the combustion chamber,

the valve L being closed at the said second I uncovering of the port I: y I

What I claim is: I Y 1. An internal combustion engine the four-cycle type,

having in combination, a

cylinder provided with an exhaust port and an inlet port, a closed crank-case connected therewith and providedwith ancontrolled inlet port which is uncovered when the piston travels out-ward from the craarkwa'se into the cylinder,

crank case and opening into thcylinder-be;

low the lowermost boundary of the combustion chamber, a piston having a'chan iber in its headprovided with two 'ports, one leading into the cylinder and'iheothentadapb' 110 ed to register with the by-pass opening when the piston is near the limit of its outward stroke, a conduit for furnishing a fuel a by-pass leading from the p charge at the inlet port of the cylinder, means for uncovering said port only during the suction stroke and means for uncovering the exhaust port. only at a period during the. scavenging stroke. the said contents of the crank-ease being compressed by the outward travel of the piston and entering the piston chamber when the piston port registers with the by-pass at the limit of its outward travel, whereby a second fluid for cushioning and for combustion is introduced. into the cylinder substantially as deseril'wd.

2. An internal combustion engine of the tour-cycle type. having in combination a cylinder provided With an exhaust, port and an inlet port, a closed crank-case connected therewith and provided with a controlled inlet port which is uncovered when the piston travels outward from the crank case into the cylinder. :1 by-pass eading from thecation in the presence of two witnesses.

crank case and opening into the cylinder below the lowermost boundary of the combo tion chamber. a piston having a spacious; chamber in its head provided with two? ports, one leading into the. eylinde' and the 1 other adapted to register with the bypass opening when the piston is near the limit of its outward stroke, the said ports being spaced at opposite extremes of the piston chan'iber, the latter thereby being adapted to act as a storage or retarding chamber, a conduit for furnishing a fuel charge at the inlet port of the cylinder, means for uncover ing the said inlet port only on the suction stroke, and n'leans for uncovering the exhaust port only at aperiod during the scavenging stroke, said contents of the crank case being compressed by the outward travel of the piston and entering the piston chamher. when the piston port registers with the, hy-pass at the limit of its outward stroke, being there slightly retarded by said arrange mcnt ott'said chamberbefore entrance into the cylinder. substantially as described.

In testimony whereof, I sign this specifi- (lrlCORUE I GLAUS.
