GAS-ENGINE.

' Patented Nov. 7,1916.

Application filed April 1, 1912. Serial No. 687,817.

To all whom it may concern:

Be it known that I, ROBERT S. MOORE, a citizen of the United States, residing at Washington, in the- District of Columbia, have invented certain new and useful Improvements in Gas-Engines, of which the. following is a description, reference being had to the accompanying drawing and to the,

means whereby air is forced by the rotation of the engine, into the cylinder, for scavenging the same, and supplying air to the combustible fluid.

A further object of the invention is to provide means whereby the combustible fluid is fed directly to the cylinder through the action of centrifugal force.

is a sectional view through the casing showing one of the cylinders in side elevation; Fig. 3 is a sectional view through one of the cylinders, taken in the plane ofrotation, also showing the crank connection; Fig. 4 is a sectional view of the cylinder similar to thatof Fig. 3, with the piston in a different position; Fig. 5 is a detail view showing the exhaust valve operating cam in edge view; Fig. 6 is a detail showing the exhaustvalve operating cam in side view.

The invention is applied to a gas engine which "consists of a supporting rotating casing and a cylinder which rotates therewith.

In the cylinder is a piston which has a relative movement to the cylinder. On the side of the cylinder in the direction of rotation, is an air intake which is formed with a funnel-shaped mouth sons to increase the amount of air taken into the cylinder. Ad-

' jacent the air intake. and at a point so as to be uncovered by the piston after the air intake is uncovered, is an intake port for the combustible fluid. The combustible fluid is fed to said intake port by centrifugal force. The exhaust valve is located in the end of the cylinder, and is so timed-that as the piston moves so as to uncover the air intake, air will rush into the cylinder to scavenge the same, and provide pure air so. that when the fuel intake is open, the liquid will be forced into the cylinder, and thoroughly mixed with the air, after which it is compressed and exploded, and an explosion is brought about for each relative reciprocation of the piston.

Referring more in detail to the drawings, the engine consists of a supporting casing 1 which is mounted to rotate in suitable bearings. A stationary crank shaft 2 is carried by

crank arms

3, 3, and the casing rotates about said crank. The cylinders 4,.are carrled by the casing 1, and as shown in Fig. 1, I have provided seven cylinders. It is obvious however, that anv desired number of cylinders may be used, although I prefer the number herein illustrated.

The cylinder is provided with an exhaust closed by a valve (iivhich is carried by a valve stem 7. A stem is pivoted to alever 8,

which in turn is pivoted to arod 9 carrying a roller 10. Said rod is pivoted at its lower end to a link 11, which guides the reciproca tions thereof. Each cylinder carries its exhaust valve and operating rod 9. Mounted on a flange 12, which is carried by the stationary'crank shaft, is a bracket 13 carrying the exhaust operating cam 14, There is a single cam which operates in turn upon the exhaust valves of the various cylinders. In Fig. '6 I have shown the roller 10 as moving out on the exhaust cam 14, which will raise the outer end of the lever 8, depressing the stem 7 of the exhaust valve, and opening the valve. This valve will be held open while the roller is traveling on the concentric portion of the cam 14, after which the roller 10', passing ofl the cam, allows the valve to seat. I v

Mounted in each cylinder is a piston" 15 which is' pivoted to a connecting rod 16. The connecting rods cooperate with the crank. shaft in the usual manner. An air intake port 17 is formed in the sideof' the rotates. This intake opening as 'herein shown is formed w th a'funnel-shaped'col- .cylinder,,which isin advance as the cylinder posed relative'to the air intake, as to he 1 uncovered by the piston, later than the a1r intake. Formed on the casing of the engine is. ,a flange 20 which is bent towardthe center of the casing as at 21, so as to form an annular pocket or trough 22. A plpe 23 leads from a suitable opening in the bottom of-the pocket to the fuel intake port 19, for eachcylinder. The combustible fluid is led through a supplypipe 24 to the trough or pocket 22. The supply of fuel may be regulated so that the proper amount of fuel may be fed to said pocket. This pocket rotates with the casing of the engine, and therefore, when said engine is rotated, the fuel Wlll be thrown by centrifugal force against the outer face of the pocket, and--w1ll be also forced through the pipes 23 into the cyllnders when the intakeports for the fuel are uncovered. The combustible gases in the cylinder are exploded by'the usual spark plu 25...,

The cylindrical part of the piston head is of suflicient length to cover the fuel-intake when the piston isjin its extreme outer position so-that this fuel intake is only uncovered when the piston moves inward relative to the cylinder. This cylindrical portion of the piston may be made of sufficient length for this purpose, entirely about the piston, or it may be carried down on one side as illustrated in the drawings.

In the operation of my device, the combustible fuel is supplied through the pipe 24, and the pocket 2'2 properly supplied or filled with fluid so that it, 'will be thrown by centrifugal force into the cylinder. Starting with'the parts shown as positioned in Fig. -3, the, gases or combustible fluids are under compression, and upon an explosion of thejzgases, the piston will be given a movement relative to the cylinder and will move tov the position-shown in Fig. 4. The

air intake port 17 will first be uncovered by the piston. The cam 14 controlling the ex- 'haust valve is so positioned that as soon as the air intake port is uncovered, the exhaust port will be opened and the air collected by the funnel will be forced into the cylinder and through the cylinder to scavenge the same. After theiburnt gases are forced fr'om'the cylinden jthe exhaust port will be closed and the cylinder at this time will be filled with substantially pure air. Thecon-v tinuedi'elative movement of the piston uncoversfthe fuel. intake 19, which allows a certain amount of fuel to be forced into the cylinder bycentrifugal force. The relative outward movement of the piston will close the fuel intake port and thenthe air intake port finally compressing the gases, after which they are exploded and the cycle of operation repeated. It will be apparent therefore, that I have provided a two cycle engine wherein the cylinder is thoroughly scavenged by air forced through the cylinder, due to the rotation of the cylinder, and wherein the fuel is fed direct to the cylinder by centrifugal force.

Whilel have shown the invention as applied to' a two-cycle gas engine, itis obvious that from certain aspects some of the features of the invention may be used in connection with othertypes of gas engines.

It is obvious that minor changes in the details of construction and the arrangement of parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus particularly described my invention,'what I claim as new and desire to secure by Letters Patent, is:

1. A gas en ine including in combination a rotating casing, a cylinder carried thereby, a piston in said cylinder, an air intake in said cylinder adjacent the inner extreme position of the piston and on the advance side of the cylinder in the direction of rotation, a collecting funnel connected with said air intake and projecting in the direction of rotation of the cylinder, and a fuel intake for the cylinder through which fuel may be supplied directly to the cylinder, said fuel intake being free fromvalves and positioned so as to be uncovered by the piston subsequently to the uncovering of the air intake.

2. A gas engine including in combination a rotating casin a cylinder carried thereby, an annular poc et carried by and rotating with the casing, said pocket having its outer surface closed and having a. port leading from the extreme outer portion thereof, said cylinder having a fuel intake port adapted to be uncovered by the piston, and a pipe connecting said port to the intake port in the cylinder, whereby a combustible fluid may be carried by centrifugal force from the pocket through the pipe to the cylinder, an air intake for the cylinder on the. advance side thereof in the direction of rotation, and a funnel for collectingand forcing air through said intake into said cylinder,

.said air intake'being disposed so as to. be

uncovered in advance of the fluid intake.

1 3. A gas engine including in combination, 1

tion, said air intake having a collecting funnel whereby air is forced by the rotation of the cylinder into the cylinder, a fuel intake located adjacent the air intake so as to be uncovered by the piston subsequently to the air intake, and means controlled by centrifugal force for supplying fuel to said fuel intake, said fuel intake being free from valves whereby a free and unobstructed passage is provided for the fuel during the intake period.

4. A gas engine including in combination a rotating casing, a cylinder carried thereby, an exhaust valve in the outer end of the cylinder, an air intake adjacent the inner position of the piston and on the advance side of the cylinder in the direction of rotation, said air intake having a collecting funnel whereby air is forced by the rotation of the cylinder into the cylinder, a fuel intake Copies of this patent may be obtained for located adjacent the air intake so as to be uncovered by the piston subsequently to the air intake, a flange carried by the casing and constructed to form a pocket having its outer face closed, a pipe leading from the outer face of the pocket to the fuel intake for the cylinder, and means for supplying said pocket with fuel whereby said fuel is carried by centrifugal force against the bottom of the pocket and through the pipe to said cylinder, said fuel intake being free from valves whereby a free and unobstructed passage is provided for the fuel during the intake period.

In testimony whereof, I affix iny signature, in the presence of two witnesses.

ROBERT S. MOORE.
