CONTINUOUS OILING AND FILTRATION APPARATUS.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed November 28, 1913. Serial No. 803,431.

To all whom it may concern:

Be it known that 1, WILLIAM W. Nuonu'r, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Continuous Oiling and Filtration Apparatus, of which the following is a specification.

This invention relates to an apparatus in which both the oil pump and the filter will be continuous in operation whenever the apparatus to which it is applied is also in operation, with means insuring that the pressure of oil circulated will be a certain predetermined amount and will not exceed this pressure.

The principal object of the invention is to provide new and improved apparatus for circulating oil, maintaining it at constant and uniform pressure and for providing pumping and filtering devices which will operate continuously when the engine is operated.

For the attainment of these ends and'the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts generally shown in the accompanying drawing and described in the specification, but more particularly pointed out in the appended claims.

In the drawings Figure 1 is a perspective view of a complete apparatus constructed in accordance with the principles of my invention and applied to an engine of the reciprocating type; and Fig. 2 is a detail of the pump and relief valve connections.

In the drawings, the numeral 5 designates generally an engine of the reciprocating type having eccentrics 6 and other reciproeating and rotary parts, to which the present invention is applied. The bearings of an engine of this type are usually lubrlcated by a continuous flow of clean oil which is supplied through a system of oil circulating mains designated generally by the reference numeral 7. A number of drip and discharge valves are connected to the circulation mains 7v in the well'known manner, as illustrated in the drawings, and at the highest point of the apparatus is a gravity O1l receptacle 8 to which oil is discharged through a manually controlled valve 9.

Used oil is collected and discharged into a continuous filter 10 by means of the oil return mains 11. This filter 10 comprises any suitable type of continuous filter which is provided with a continuous water overflow 10 and with a clean oil receptacle 12. Connected from the top of the gravity ,receptacle 8 to the clean oil receptacle 12 is an overflow pipe 13. Also connected with the clean oil receptacle 12 is a pump suction pipe 14. A pump 15 of the single acting reciprocating type is connected at one end to the engine base and at the other end to a reciprocating part of the engine, as for example, to one of the eccentrics 6 and has a single suction and discharge pipe 16. Interposed between the suction pipe 14 and the pump suction and discharge ipe 16, is a check valve 17, and interposed between the circulation mains 7 and the pump suotions and discharge pipe 16 is a check valve 18. These check valves are of any Well known type and cause the fluid to be drawn from the suction pipe 14 through the check valve 17 and to be discharged through the check valve 18 into the oil circulation mains.

A relief valve 19 is connected to the circulation mains 7, and extending from the relief valve is a discharge pipe 20 which is connected around the check valves 18 and 17 and with the suction pipe 14 so that if the pressure of the fluid pumped is too great the oil will flow through the relief valve 19 through the pipe 20 to the pump suction pipe 14.

In operation the pressure of oil in the oil circulation mains is controlled by means of the manually operable valve 9, which permits more or less of the oil pumped to pass to the reservoir 8. If a large amount is allowed to pass to the reservoir 8 the pressure in the oil circulation mains will be somewhat reduced, and if the opening of the valve 9 is restricted the pressure of the oil in the circulation mains may be much greater. The relief valve 19 limits the pressure of the oil in the circulation mains, and when the ressure becomes too great the oil will simp y be shunted through the bypass 20.
