INTERNAL COMBUSTION ENGINE Filed Feb. 12, 1930 Patented Feb. 13, 1934 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to improvements in in ternal combustion engines and more particularly to the type thereof adapted particularly to road vehicles, aircraft and similar apparatus. One
I object is to provide an engine that is compact in assembly, light in weight, economical in the use of fuel and one wherein the cylinders are arranged vertically on the chassis thus providing vertically reciprocating pistons with the attendant advantages thereof.
A further object is to provide an engine of the high compression type, having a long stroke and small bore and one wherein the construction and assembly is such as to insure steadiness in operation, freedom from excessive vibration, quiet operation and proper engine balance.
With the foregoing and other objects in View the invention consists in the combination and ar rangement of parts to be hereinafter fully described, pointed out in the claim and illustrated in the accompanying drawing which forms a part of this application for patent and in which Fig. 1 is a vertical sectional view through an internal combustion engine constructed according to the present invention.
Fig. 2 is a top plan view of Fig. 1.
Fig. 3 is a View in side elevation, enlarged, of the connecting rod employed.
Like reference characters denote corresponding parts throughout the several views.
In the preferred form of my invention herein set forth I provide a cylinder casting comprising a plurality of vertical cylinder chambers wherein a plurality of open ended vertical cylinder 35 liners for the pistons are arranged which latter members are actuated by cams in a well known manner.
The cylinders are arranged in pairs, the successive pairs being disposed upon opposite sides of the crank shaft, the members of each pair of cylinders being connected by a common passageway and the pistons of each pair of cylinders being connected together so that they work in unison.
The reference numeral 1 denotes the cylinder casting which is divided into a plurality, two or more, of cylinder chambers 2, 3 arrangel in pairs and within each chamber is an open ended cylinder liner 4, said chambers and cylinder liners being connected at their inner ends by a passageway or recess 5. Each cylinder liner is formed with an intake port 6 adapted to register with a fuel port 7 in the casting, and with an exhaust 55 port 8 adapted to register with a like port 9 in the casting, and a spark plug 10 is arranged centrally of each passageway or recess 5.
Within each cylinder liner is a piston 11 and the two pistons 11 of each pair of cylinder liners are connected by piston rods 12 to a pin 13 which pin is connected by the head 14 of a connecting rod 15 to the crank shaft 16. This type of engine is capable of great power as the cylinders are of small bore and the pistons of long stroke. Upon the intake stroke of the two pistons of a pair of cylinders the fuel charge is forced into both cylinders, it is compressed at the same time by the inward stroke of the pistons and is fired immediately after the crest of this stroke is reached, the explosion taking place in the passage or recess 5 and in the upper ends of the two cylinders. The exhaust stroke is the outward stroke of the pistons, the burnt gases being evacuated after the pistons pass the ports 8.
The successive pairs of pistons are arranged to be at relatively opposite stroke extremities at the same time and the successive cranks of the crank shaft are 180 degrees apart. The crank shaft 16 is provided with a separate crank 17 for each pair of cylinders. The cylinders of each pair are disposed in a common vertical plane and the vertical planes of both pairs of cylinders are parallel to each other and to the axis of the crank shaft.
What is claimed is:
In an internal combustion engine, the combination of a cylinder casting, a plurality of open ended cylinder liners arranged in pairs, the members of each pair being spaced apart, a crankshaft in line with the longitudinal centers of said cylinder liners, said pairs of cylinder liners being disposed consecutively upon opposite sides of said crankshaft, the members of each pair of cylinder liners being connected by a common combustion chamber, pistons in each pair of cylinder liners movable together in a common direction, and a connecting rod connecting each pair of pistons with said crankshaft, said connecting rods being disposed between the members of the pairs of cylinder liners.
JOHN P. STATHAS.
