ATTORNEY United States Patent DEBRIS COLLECTOR FOR ENGINES Andrew Petersen, Gordon, Nehr. Application November-15, 1954, Serial No. 468,875 2 Claims. (Cl. 210-57) The instant invention relates to internal combustion en inesand has for an object to provide a means for colletting sediment, moisture and the like debris contained in; the crankcas erthe engine in a manner whereby said debris may be readily discarded.

Another object of the invention is to provide a device having a valve plate havin'ga means for rotating the plate exteriorly of the device for decommissioning said valve at desired times.

A further object of the invention is to provide a shaft for said valve plate having resilient journal bearings arranged toQgrip said shaftfor maintaining said plate in a pie-selected position with respect to'other portions of the device andat desired times.

Other, and further objects and advantages of the invention will-be understood from the following detailed description thereof. 7

In the drawings:

Figure 1 is a side view of the new device applied in a position of use to and below the crankcase of an internal combustion engine.

Figure 2 is a transverse sectional view of the new device on an enlarged scale.

It is well known that during operation of an internal combustion engine a certain portion of the lubricating oil carried in the crankcase of the engine turns to sludge and that moisture collects in said crankcase resultant from condensation, and the instant invention aims to provide a device in which sludge, sediment, moisture and the like debris become deposited at times when the engine is not operating such as at times when the several parts of the engine are stationary over night.

While one embodiment of the invention is illustrated in the above-referred to drawings, it is to be understood that they are merely for the purpose of illustration and that various changes in construction may be resorted to in the course of manufacture in order that the invention may be utilized to the best advantage according to circumstances which may arise, without in any manner departing from the spirit and intention of the device, which is to be limited only in accordance with the appended claims. And while there is stated the primary field of utility of the invention, it remains obvious that it may be employed in any other capacity wherein it may be found applicable.

In the accompanying drawings, and in the following specification, the same reference characters are used to designate the same parts and elements throughout and.

in which the numeral 9 refers to the invention in its entirety and 10 indicates the crankcase of an internal combustion engine, said case being represented by means of broken lines.

A lower portion of the crankcase is provided with an aperture the wall of which is provided with a screwthread 11 for receiving a drain plug in said aperture. In the practice of the instant invention this said drain plug is removed and discarded and the new device substituted for said plug.

The new device includes a neck or sleeve 12 having a 2,7 54,969 Patented July 17, 1956 'ice screw thread 13 which is complemental to the thread 11 of the crankcase whereby at times when said threads 11 and 13 are engaged together the later described device is firmly attached to the crankcase.

Preferably thesleeve is provided with an annular bushing 14 for'supporting a resilient gasket 15 in a manner whereby the gasket is compressed between the bushing or flange 14 and the bottom of the crankcase for preventing the new device from becoming detached from the crankcase resultant from vibration incident to road traveling movements of the vehicle which said engine propels.

The sleeve 12 is elongated, the major axis thereof being disposed at a right angle with respect to. the bottom of the crankcase.

Across the sleeve '12 a shaft 16 extends, the ends of said shaft being journaled in'oppositely disposed portions of the annular wall of the sleeve.

Resilient bearings or journals 18 and 19 encircle oppositely disposed end portions of the shaft 16, said members 18 and 19 being embedded in the wall of the sleeve 12. These resilientbearings 18 and19 are each provided with a medial aperture through which the shaft 16 ex tends and said apertures are normally of slightly lesser diameter than the diameter of the shaft 16 whereby the memberslS and 19'frictional1y grip the shaft for maintaining the shaft in .a pro-selected position at desired times.

Oneend of the shaft 16 extends beyond the side wall of the sleeve being provided with a flared portion 17 which an operator may grip between his thumb and forefinger for rotating the shaft 16 exteriorly of the sleeve.

A vvalveis provided in the sleeve said valve being in the form of a. circular plate 20, the 'perimetrical edge of which snugly engages the inner annular wall of the sleeve 12 at times when the flared end 17 is turned at an angle of degrees with respect to the showing thereof in Figure 2. The plate 20 is provided with a tube 21 soldered to said plate. The shaft 16 extends through said tube, being attached to the tube and to the plate 20 by means of a set screw 22. The employment of the set screw 22 facilitates an assemblage of the plate within the sleeve 12. By applying the bit of a screw driver to the screw 22 at the times when the plate 20 is transversely disposed across the sleeve, the parts become operatively locked together and at the time the flared portion 17 of the shaft 16 is turned at an angle of turn of 90 degrees with respect to the showing thereof in Figure 2.

A cover 23 for a later described bowl is provided, said cover being formed integral with the sleeve. The cover is provided with an annular flange portion 24, the inner wall of which is provided with a screw thread 25. The new device further includes a bowl 26 having an annular side wall 27. The wall is provided with a screw thread 28 for engagement with the thread 25 of the flange 24 for operatively locking the bowl to the flange. The bowl 26 is formed of transparent material. A resilient gasket 29 is disposed between the upper edge of the side wall 27 of the bowl and the adjacent surface of the cover 23 as shown for preventing a leakage of debris at this point.

The bowl 26 provides a trap for a collection of sediment, sludge, water and like debris therein.

Operation Before the engine is started the operator causes the valve plate 20 to be turned so that communication between the interior of the bowl 26 and the interior of the crankcase is cut off for preventing any debris which may have collected in the bowl 26 from becoming admixed with the oil in the crankcase. At times when the operator is not causing the engine to operate, the said operator turns the valve plate 20 to the position shown in Figure 2 whereby, after an interval of time, debris moves d0wnwardly into the bowl 26.

By inspecting the interior of the bowl through its transparent side wall, the operator may note that a suflicient amount of debris has collected in the bowl to warrant unscrewing the latter from the cover 23, whereupon the bowl is cleansed and replaced.

From the foregoing specification, it will become apparent that the invention disclosed will adequately accomplish the functions for which it has been designed and in an economical manner and that its simplicity, accuracy and ease of operation are such as to provide a relatively inexpensive device, considering what it will accomplish and that it will find an important place in the art to which it appertains when once placed on the market.

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 lengthy description is regarded as unnecessary.

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.
