UNMTE STATES INTERNAL-COMBUSTION MOTOR.

Application filed March 5, 1924. Serial No. 697,093.

To all '1o/10m, it 'may emmer/a.'

Be it known that I, FERDINAND llinainn, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented a new and Improved Intern:il-Combustion Motor, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in internal combustion motors. y

It is one of the primary objects of the invention to provide a power cylinder to which a combustible charge and a charge of air are supplied under pressure.

It is a further object of the invention 'to construct the motor in such a manner that the combustible charge will be supplied to the power cylinder iist andvsubseqnently 4placed under compression at which time the air under compression is supplied to the power cylinder.

lt is a still further object of the invention to construct the motor in such a manner that the foregoing operations are carried out automatically. l

lVith thc above and other objects in view, reference is had to the accompanying drawings, in which The ligure is a vertical Sectional View of a motor constructed in accordance wit-l1 the present invention, the view heilig taken at right angles to the crank shafts of the motor.

Referring more particularly to the drawings, the reference numeral 5 designates the lower section of a two-part motor crank case, the reference numeral 6 designating the other section thereof. These sections 5 and 6 are secured together by means of bolts 7 to form the con'lplete crank case.

Mounted in the crank case there are two cranks 8 and 9, and connected to the cranks 8 there is a connecting rod l0, a connecting rod ll heilig connected to the crank 9.

' Mounted upon the crank 8 Ithere is a gear wheel 12, and mounted upon the crank 9 there is a gear wheel 13, such gear wheels 12 and 13 having intermeshing engagement with each other. The connectingrod 10 is pivotally connected at its upper end, as at 14, to the piston 15, and such piston is mounted in a cylinder 16 which constitutes the power cylinder of the motor. This cylinder has an exhaust port 17 as shown.

The upper end of the connecting rod 11 is pivotally connected, as at 18, to the piston 19, working in a cylinder 20, and such cylinder 29 has a cylinder 21 preferably of smaller diameter carried by its upper portion. The cylinder 20 is provided with an air intake 22, and ai discharge port 23,

which discharge port is controlled by a check valve 24. Connected to the piston 19 and extending upwardly therefrom, there is a tubular member 25, the upper end 26 of which is open, the tubular member being providedwith a port 27 near its lower end, and passing through a chamber 28 formed in the upper cylinder.

Mounted in the upper cylinder 21 there is a' piston 29, and such piston has a skirt portlon depending therefrom. The piston 29 1s connected. with the piston 19 by the tubular member 25 heretofore mentioned. The skirt portion 30 of the piston 29 is provided with two ports 3l and 32 and such ports are adapted to alternately coincide with a passageway 33 leading to the cylinder 16. On one side of the cylinder 21, there is formed an elongated chamber 34, and mounted in said chamber there is a piston 35, to the upper end of which is connected a rod 36, which in turn is pivotally connected, as at 37, to an angularly projecting arm 38 of a rod 39. This rod 39 is connected 1n any desired manner to the tubular member 25 so that as the'pistons 19 and 29 reciprocate, the piston will be caused to reciprocate therewith.

Leading from the lower end of the cham ber 34 heretofore mentioned there is a pipe 40. This pipe 40 has communication with the chamber 34 and is controlled by a check valve 41. The opposite end of the pipe is connected as at 42, to the cylinder 20, and leads into and has communication with the chamber 28 heretofore mentioned. Leading into the chamber 34 intermediate of its ends, there is a pipe 43, which has 4communication with said chamber, and the passage of the pipe 43 is controlled by a check valve 44. The pipe 43 constitutes an inlet for lubricating oil, and the pipe 40 is the means by which this oil is discharged into the chamber 28. To lubricate the tubular member 25 and the piston 19 leading into the chamber 34 above the pipe 43, there is a ipe 45, the passage of which is controlled ly a check valve 46, and this pipe 45 constitutes a gas inlet by means of which gas is admitted to the chamber 34. The chamber 84 has communication with the cylinder 21 by means of ports 47 and 48, which are in register with each other as shown in the drawings.

The device operates in the following manner:

It will be noted that the two cranks 8 and 9 are positioned nearly opposite to each other in such a manner that as the piston 15 moves upwardly the pistons 19, 29 and 35 will movey downwardly, and vice versa. lVith the parts in the position shown in the drawings, the'piston 15 has placed a charge of air under compression and a charge of combustible fuel under compression is being admitted to the cylinder 16 in the compression space thereof. As the crank 8 passes over top dead center, the charge is ignited and the piston 15 is forced downwardly. As the piston 15 is forced downwardly, the pistons 19, 29 and 35 more upwardly. The piston 19 in this movement places a charge of air under compression in the cylinder 20 and the piston places the combustible fuel in the chamber 34 under compression.

vWhen the crank 9 reaches top dead center and the crank 8 is approximately at lower dead center, the air placed under compression in the cylinder 2O will rush through the port 23 to fill the cylinder 1G. Simultaneously with this operation the combustible fuel in the chamber 34 will, through the medium of the ports 47 and 48, pass into the cylinder 21. Immediately the piston 35 draws oil. into the lower portion of the chamber 34 through the pipe 43 and check valve 44. As the piston 15 moves upwardly to place the air under compression which was delivered to the cylinder 16 by the piston 19, the pistons 19, 29 and 35 descend. This operation places the combustible charge in the cylinder 21 under compression and as the port 31 in the skirt 30 of the piston 29 registers with the passage 33 in the cylinder 16, this charge of combustible gas under pressure rushes into the cylinder 16.

From the foregoing it is apparent that the above described operation is automatically carried out so long as the motor is in operation, and that, through the medium of the mechanism em loyed, the power cylinder of the motor 1s supplied with air and gas under pressure, the gas being introduced into the cylinder after the air therein-has been placed under compression.
