vLUBRICA'JIION SYSTEM FOR INTERNAL-COMBUSTIO ENGINES. 'i

Application led October 1, 1917. Serial No. 194,182.

VThis invention relates to improvements in lubricating systems for internal combustion engines.

The principal Object ofmy invention is to provide a lubrication system in which the oil is fed by gravity from an oil reservoir through suitable passages to the bearings which are to be lubricated, said system having simple and effective means whereby vthe rotating fly-wheel of `the engine lifts the lubricating oil from the lower part of the crank case to the reservoir', said oil being diverted and directed from thefiy-wheel casing'into the oil reservoir'by means of ,a suitably-disposed baffle. t VrA further vobject of `my invention is to provide a simple and convenient arrange- Vment by which the upper 'part of the wheel casing, the voil reservoir and the upper half of the forward crank shaft bearing are formed integrally, said'oil reservoir and flywheel Casing and said reservoir and bearing being yconnected bysuitable ports and passages. l Y

A further object of my invention l1s to provide a simple and effective means for securely holding a strainer in place in said oilrese'rvoir and `at the same time holding thev cover in place over said reservoir.

Y Further objects, and objects relating to economies of manu-facture and details of construction, willy definitely appear from the detailed description to follow: U

I accomplishthe vobjects of my invention by the devices'and means following specifications. 1,

A structure constituting a preferred 4embodimeiitv of my invention is illustrated in the accompanying drawings,forming a part of-this specification, in which:

Considering the numbered parts of the drawing, I have shown an engine comprising l a crankcase made up of the lower half rv10 and the upper half 11, on which the` cylinder Y' block 12 is mounted.y The. crank shaft '14 is journaled in the crank case in. the usual i manner and the fly-'wheel 15 is secured to the rear end of the crank shaft, the lower half of saidy-'wheel being disposed within the crank'case 10 while its upperfhalf is disposed within the fly-wheel casing 13 as shown in Figure I. A partition 16 in the lower half of the crank case 10 Adivides the portion ofthe crank case in whichthe iiywheel'turns from thefrest of said crank case andaids in supporting an oil pan'17 The upper wall of the vfly-wheel casing ljis formed with a downwardly extending fiange `18,and the wall of the iy-wheel casing ad-` jacent'said flange is inclined upwardlyjatil) so that said flange 18 Aand saidwall 19 form a baffle so thatth'e lubricating oil carried upwardly by .theily-wheel as'it turns is di- 'which/communicates' with the oil reservoir 20,vforme'dv integral with the ily-wheel cas- 4ingl.` ,Y fi
