SPLASH LUBRICATING SYSTEIVL Application filed October 8, 1921.

To all whom it may concern:

lie it known that we, LAWRENCE M. ENnnn-s and MICHAEL A. Ennnus, both citi- 776115 of the United States, and residents of Dane, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Splash Lubricating Systems; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention refers to splash lubricating systems usually employed in connection with the crank case of internal combustion engines.

The invention has, for its primary ob eet, to provide a simple, economical and effective oil reservoir for said crank cases or splash pans, having means for predeterminately controlling the level. of oil within the crank case with respect to the reservoir.

WVith the above objects in view, the invention consists in certain peculiarities of construction and combination of parts as are hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

The drawing illustrates a sectional elevation of an engine crank case and oil reser voir equipped with feed mechanism embodying the features of my invention.

Referring by characters to the drawings, 1 represents an engine crank case, and 2 an oil reservoir, which is of the desired capacity. For example, this reservoir is ordinarily provided for containing one and onehalf gallons of oil. The reservoir is fixed to the tank in any suitable manner and properly positioned with reference to the bottom of the crank case, whereby oil from said reservoir is fed therein by gravity. The reservoir is provided with a filling neck 3, having a cupped head 3 adapted to receive the threaded shank 4 of a cap closure, which shank is in threaded union with the end of the filling neck.

In this exemplifieation of our invention, the cap is also provided with a depending oil gauge stem 5. Hence when it is desired to determine the level of oil in the reservo1r, the can can be removed and the moistened A stem will indicate the depth of oil.

The essential element of our invention includes a vent pipe 6, which pipe extends through the reservoir, as shown, from top to bottom and has an open mouth 6, whereby atmospheric pressure is admitted thereto.

Specification of Letters Patent.

Patented June 20. 192.

Serial No. 506,374.

The lower end of the vent pipe is connected by a T 7 to a gravity feed pipe 8, which feed pipe is coupled to the bottom of the tank 1, and also by a branch 8' to the bottom of the oil reservoir 2. The branch pipe 8 is provided with a controlling valve, whereby the supply of oil can be cut off from the reservoir when desired.

Loosely mounted within the vent pipe 6 is the long leg 10 of an oil level gauge pipe of the goose neck type. The short leg 10 of this pipe is connected to the long or main leg in the form of a goose-neck, and said short leg extends downwardly into the reservoir through a stuffing box 11', whereby the oil gauge pipe, as a whole, can be raised or lowered and held in such adjusted position vby its frictional engagement with the parts of the stuffing box.

From the foregoing description it will be seen that when the oil reservoir is filled or partly filled, and it is desired to maintain a predetermined level of oil within the bottom of the crank case, all that is necessary is that the operator raise the oil level gauge pipe to a position, where its bottom or mouth is, for example, 3 inches from the bottom of the crank case. This elevation of the mouth of the leg 10 will positively fix the level of oil in the crank case which is fed from the reservoir, and when the fixed level is reached, the mouth of long leg 10 of the gauge pipe will break the oil seal in connection with the vent pipe extending upward from the feed pipe whereby a further feed of the oil into the crank case will be checked. In other words, the position of the lower end of the oil gauge pipe will determine the depth of oil to be maintained in the crank case, and when the depth of oil in said crank case drops below the bottom of the gauge pipe leg 10, the feed will be broken by the air gap in con nection with the vent pipe 6.

It will be noted that the short leg of the oil level gauge pipe is of such length with respect to the long leg, that said pipe, as a whole, can be adjusted to approximately the capacity of the oil reservoir without causing the short leg to be disconnected from its stuffing box union.

l Vhile we have shown and described one simple exemplification of our invention, it is understood that we may vary the structural features of it within the scope of the claims as they will be hereinafter interpreted by those skilled in the art.

We claim:

1. An. oil feed mechanism for engine ci'ank cases comprising a reservoir, a valve controlled feed pipe extending from the reservoir into the bottom of the crank case, a vent pipe in communication with the feed pipe, the same being" extended above the normal line oi oil maintained in a goose neck pipe having a short leg and a long leg, said beingconnected rigidly together, the long leg being adjustable Within the vent pipe to predeterminately c011- trol the level of oil Within the era nl: case, said legs being simultaneously adjustable;

2. Ail oil feed mechanisn1 comprising an oil splash pan, an oil reservoir associated therewlth, a valve controlled feed pipe in the reservoir, and

communication with the reservoir and splash pan, a vent pipe connected to the feed pipe and extending through the oil reservoir to a point above the same, a stuffing box extending from the top of the oil reservoir, a U-shaped pipe having short leg adjustable Within the stufling box, and a relatively longer leg adj nstably mounted in. the vent pipe, the lower end of said long leg being adapted to control the lever of oil within the splash pan.

In testimony that We claim the foregoing We have hereunto set our hands at Dane, in the county of Dane and State of Wisconsin.
