OILING- SYSTEM FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented Au 15, 1916.

To all whom it may concern:

Be it known that we, Eennn'r. T. Gnonens and JAcon E. GRAMLICH, citizens of the United States, and residents of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Oiling System for Internal-Combustion Engines, of which the following is a specification.

This invention relates to base compression, internal combustion engines and particularly to lubricating means for the crank shaft bearings whereby the crank shaft bearings are sealed by oil and hence the compressing and suction actions of the piston do not have any' effect outside of the crank casing, or in the contiguous casing if the engine is multicylinder, but are confined wholly to the crank casing.

The invention consists in the novel fea tures of construction hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings, in

' which like characters designate corresponding parts in all the views.

Figure 1 is a vertical longitudinal sectional view of an internal combustion engine provided with our invention. Fig. 2 is an enlarged vertical cross-sectional view through the crank casing, parts being removed.

1 designates the cylinders of a two-cycle, base compression, internal combustion engine, 2 the pistons movable therein, 3 the bases or crank casings, 4 the crank shaft journaled in bearings 5 in the crank casings, and 6 the rod connecting each piston 2 and its crank 7.

S are oil ducts leading from the crank casing to the bearings 5, these ducts having upwardly extending portions which open into the crank casing in position to receive the oil running down the sides of the crank casing after being splashed thereon by the crank 7 and in position to be subject to compression and suction actions of the pis ton, so that the oil after it reaches the bearings through the ducts 8 forms oil seals which are maintained by the alternate suction and compression effect of the piston. As here shown, the ducts open into pockets 9 formed in opposite sides of the crank casing 3, these pockets being open at their inner sides and tops so as to receive the oil running down the inner sides of the crank casing and also oil being splashed by the crank/Z, and as here shown, the front and rear sides 10 of the pockets are inclined toward the bottom thereof through which the passages 8 open, and the outer sides 11 of the pockets incline. inwardly and upwardly and overhang the bottom and the sides 10 and thus any oil splashed against the upper portions, as 12, and the top of the crank casing will adhere to and run down the inclined sides into the pockets instead ofdripping to the bottom of the crank casing. The bearings 5 usually include sleeves or bushings 13 and the ducts 8 communicate with passages H in the sleeves.

In operation, oil is filled into the lower portion of the crank casing and during the movement of the crank shaft the oil is splashed in the well known manner, and owing to the pockets 9 the oil is gathered and directed into the oil ducts 8, the oil being forced through these ducts during the downward movement of the pistons and slightly withdrawn therefrom during the upward movement of the pistons. Hence, the oil in the bearings forms seals which prevent the inlet along the crank shaft of air from the outside, or of gas from an adjacent casing during the upward stroke of the piston, and which also prevent the escape of gas along the shaft during the downward stroke of the piston.

hat we claim is 2- 1. In a base compression, internal combustion engine, a base or crank casing serving as an oil receptacle, and being formed with bearings, and a crank shaft journaled in the bearings, the crank casing being also formed with ducts leading to the bearings, the ducts being disconnected from the exterior of the casing except through the bearing openings, and each having an up wardly extending portion located abovethe bearing and opening into the interior of the crank casing in position to receive oil running down the sides of the crank casing and to be subject to the compressing and suction actions of the piston whereby an oil seal is maintained about the crank shaft, substantially as and for the purpose described.

2. In a base compression, internal combustion engine, a base or crank casing serving as an oil receptacle and formed with bearings for the crank shaft of the engine, the

casing being formed with internal pockets in opposite sides thereof, the pockets being located above the bearings and open at their tops and inner sides, and oil ducts leading from the pockets to the bearings, and being disconnected from the outer air except through the bearing openings, the pockets being located in position to receive oil running down the sides of the crank casing and to be subject to the compressing and suction actions of the piston whereby an oil seal is maintained about the crank shaft,

substantially as In testimony whereof, We have hereunto 15 signed our names in the presence oftwo attesting Witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 4th day of February 1914.
