SPLASH LUBRICATING SYSTEM.

Application filed November To all whom it may concern:

Be it known that we. LAXVRENCE M. EN- nnns ar lilicninr. A. ENDRES, both citizens of the United States, and residents of Dane, in the county of Dane and State of WVisconsin, have invented certain new and useful Improvements in Splash Lubricating Sys hereby declare that the folfun. clear. and exact description rig is a thereof.

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

The invention has for its primary object the provision of a simple, economical and effective oil reservoir for said crank cases or splash pan, having means for automatically controlling the level of oil within the crank case with respect to the reservoir.

It contemplates especially a gravity feed from an air tight reservoir having a cut-off arranged adjacent the crank case operating to control the amount of oil fed into the crank case by reason of a device wherein the level of the oil in the crank case controls the admission of air into the reservoir. The exclusion of air from the reservoir prevents a feeding of oil because of the formation of a vacuum in the reservoir.

An additional feature of our invention is the provision of a device whereby the air fedinto the reservoir and associated pipes is kept clean as it is gotten from the crank case.

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

Figure 1 shows a plan view of the reservoir, and part or" the crank case in section.

Figure 2 is a cross section substantially on the line 2-2 of Figure 1.

Figure 3 is a cross section on the line 33 of Figure 1; and

Figure -l is a detail of a bushing.

l'leservoir 10 is aliixed at 11 to the horizontal flange marking the union ot the crank case castings. il outlet pipe 12 leads from the bottom thereof. and is provided with a control valve 13 which may be operated to cut off the flow of oil entirely. Air inlet pipe 14 communicates with the top of reser- 17, 1921. Serial NO. 515,778.

voir 10. This pipe may be inade of rather lio'ht material to facilitate its sliding into member 15 which is provided with bushing 16, having a follower l7 and packing- 18 to prevent the escape of fluid.-

liiember 15 provided with a nipple 19 threaded in the crank case. Pipe is suitably connected to member 15 at 20. loose neck 21 leads from member 15 and has a relatively short arm connected to pet cock 22 provided with a nipple 23, threaded into the crank case. Pet cock is located above and to one side of member Member 15 chambered at 16 so as to provide communication with pipe 12. air inlet pipe 14 and goose neck 21. The air inlet pi pc 14- may be pushed downwardly into chamber 16 or with drawn to any desired degree.

In Figures 3 and 4:, the slant or character of air inlet pipe ll appears. This slant. however, is not necessary to our invention and. if desired, the pipe may be positioned vertically. Stop cocks 24- and 25 may he provided.

In the operation of the device. control valve 13 is operative to permit the exit oi oil from the reservoir 10 into pipe lt there is no oil in the crank case. the lluid is fed into pipe l2. member 15 and nipple l9. into the crank case. At the same time there is a flow of air upwardly in air inlet pipe 14 to the top of reservoir 10. thus breaking the vacuum in reservoir 10 and permitting the tree outflow of the oil which rises the crank case. Even after the oil in the crank case has passed above nipple l9; the (low of oil will continue. as air is received through nipple 23, pet cock 22 and goose neck 21. into chamber 15 whence it flows into air pipe This operation continues until the level of the liquid is above the 0nd of air inlet pipe 14. At this point the flow oi oil stops as air is not being communicated to the reservoir 10. Hence it appears that the level of the fluid in the crank case is determined by the location of the terminus of air inlet pipe 141:. Goose neck 12 need not necessarily connect with the crank case. but such location is useful in that it keeps the air which is fed into air inlet pipe 14 clean. (loose neck 12 may receive the air from any source.

Pet cocks

24 and 25 may be used to perform their customary function in connection with crank cases, if so desired, but in view of the automatic feed, they may be dispensed with.

Ve claim:

1. An oil feed mechanism for crank cases comprising a reservoir and oil pipe extending therefron, an air inlet pipe extending therefrom, a chambered member receiving said pipes a connection between said member and the crank case, said connection having a duct therein, the end of said air inlet pipe extending through an opening in said chambered member and slidable upwardly in said opcng to regulate the height of oil in said crank case, and a second air inlet pipe communicating with said chambered member.

2. An oil feed mechanism for crank cases comprising a member, a connection leading from said member and having a duct therethrongh, a crank casing receiving said con nection, an air inlet pipe and an oil pipe communicating with said member, a second air inlet pipe communicating ith said member and vertically slidable therein, said second air inlet pipe terminating at a point below the end of said first mentioned air inlet pipe and a reservoir receiving said second. air inlet pipe and said oil pipe.

3. An oil feed mechanism for crank cases 7 comprising a chambered member, a nipple thereon, a crank case receiving said nipple, air 1nlet means communicating at one end with sald crank case and at the other end 7 with said chambered member, an oil pipe and said chambered member, a second pet cock communicating With said crank case, a pipe connecting said second pet cock l said chambered member, an oil pipe cc ed to said chambered member, a third pipe communicating with said chambered member and a reservoir receiving said oil pipe and said third pipe. 7

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