1 Claim. 1

This invention relates to internal combustion engines and has for its object to provide means for preventing vapor condensation from returning into the oil pump of the engine.

Another object of this invention is to provide an arcuate cap for the rocker arm of a valve in head engine having a gutter into which the condensation of raising vapor will flow and means for directing the same outwardly of and away from the cylinder block.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure 1 is a transverse sectional view of the top of an internal combustion motor,

Figure 2 is a reduced perspective view of my device, and

Figure 3 is a similar view of a modification.

In the accompanying drawings as above enumerated and in the following specification, like characters of reference indicate like parts throughout and in which l0, indicates my invention which consists of a cap II, to fit over the rocker arm l2, of an internal combustion motor and against the upper wall l3, of the casing M, for the top of said motor. The member ll, consists of an elongated arcuate plate terminating at its lower edges in a surrounding gutter l5, inclining to an outlet I6, to which is attached a tube l'l, projecting through an aperture in the wall of the member I4. An opening [8, is provided in the center of the device through which the bolt l9, projecting from the rocker arm support 20, extends. On this bolt I provide a spring 2 I, and a washer plate 22, above the spring which bears against the top wall 23, of the member II, and holds it securely against the wall I3. From the tube ll, extends a flexible tube 24, for carrying off the drainage fromgutter 15.

In internal combustion motors vapor arises from the oil sump and other parts of the motor and passes through the apertures of the

rods

25, 26, etc., and usually collects upon the surface of the wall l3, where it condenses and a considerable part of which falls on and follows the

rods

25, 26, etc., and returns to and mixes with the oil in the sump, which of course is injurious to the motor. Therefore, I have provided the above described means of collecting this condensation and carrying it 01f from the motor.

In Figure 3 I show a modification of the invention to be used in connection with motors having a flat top motor head casing. In this form of the invention the member 21, is formed in one continuous piece, not being divided centrally and is provided on its ends with

recesses

28 and 29 to receive projections usually found in the top of the casing head at the opposing ends thereof. Otherwise, the device is arranged as the preferred form.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more length description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.

Having now described my invention that which I claim as new and desire to procure by Letters Patent is:

In combination with an internal combustion engine having overhead valves and rocker arms with tappet rods for actuating the same, and a removable inverted U-shaped casing therefor supported upon the head of said engine, of an inverted U-shape oil vapor collecting cap supported within said casing being of a similar shape thereto and disposed in contact with the inner wall thereof, said oil vapor collecting cap being formed with an inwardly disposed inclined trough bent to extend upwardly about the peripheral adge of said cap, and a discharge tube connected with the lowest portion of said trough adapted to carry off the used oil from the condensed oil vapor which collects in said trough for preventing the same from returning to the oil in the engine crank case.
