Patented Jan. 6, 1914.

To all whom it may concern: I

Be 'it known that I, Elmer. MARAN- \ILLE, a ciizfen of the United States, resid- I in the 'c ountyfo'f Summit and State of Ohio, haveinvented a certain new useful Improvement in Lubricating byste'ms, .of which the following is atfull, clear, and exact description, refierence bein had to the, accompanying drawings.

is invention relates to lubricating systerms of thety-De shown in application #545,742, filed February 1910, and, vwhile applicable in some of its various systems of machinery,

reference -to automobiles. construction, a systemis provided whereby the various parts of the engine of an automobile may be conveniently lubrlcated, andan adjus'table predetermined; level of oil may be maintained in the'enginebase, or crank case, sediment maybe automatically and con-, venientlyremoved fromsuch'base, and the surplus oil flowing 'from such base ,may be efiectively filtered, washed and cooled,- the construction assumifigjthe form of an. attaclmient, which may be applied to existing types of engine basesor crankcases by the mere substitution of a special base section or attachment for ,that usually provided. Stilhfurthe'r and gleinerally speaking, the e ned as consisting of the co 'bi'na'tions of elements and parts embodied in the claims hereto annexe and illustrated in the drawings forming part hereof, wherein- Figure 1 represents aside elevation of a .nmlti-cylinder engine having my invention applied thereto, Fig. 2 a vertical sectional view taken through the lowerportion of a crank case, '01- engine base, showing a part of my invention applied thereto, and Fig. 3 a sectional detail corresponding substantially to the line 33 of Fig. 2. H

Describing the parts by reference characters, wherein the same numerals designate like parts in the different views, 1 denotes e the hood of an automobile,2 the dash board,

I herein as of the four-cylinder type,

and 3 a. iront wheel thereof. Beneath the hood and supported by the frame in the manner is the engine, shown the cylinders being designated by the numeral 4. The cylinders are supportedby a base comprising an upper section or member 5 and ordinary features for t e. mb diwith special y means of ,down theside of the casing ln prox inlity to a lower section or member 6. The upper member may be of any ordinary or standrd'type, and is shown as provided with flan es orabutments 7v to which the lower lnem r may be secured by means of correspending? flanges 8, 8 and screw bolts 9, 4

thetwo members together-forming a crank-' case. Each cylinder will be provided with a suitable piston between which and the crank 10 'extendsjaconnecting rod 11.

The lower section 6 is provided with a sedimentvchamber 12 depending therefrom d, pr ra y Lea t chamber co municati'ng with the rounded ortion oft e base section 6 thereabove 'ertical connections 13 having passageways f Ihese passageways provide somewhat eldngate'dinouths or ports in the bpttom 'ofthelcasing proper. One internal f each-pgrt is located in a vertical line ""x tendingfthrough the center, of the connecting-rodndthe'crank center when the latter and jthe connecting r are in a sjt-raih t has or on dead center. This fl, withgtlie curved form of base section '6, is at the lowest portion of such sectionl. .The opposite side 15, is necessarily somewhat elevated with respect. to 14. Assumin that the crank shaft is driven in the direction ofthe arrow on 2 when the engineis going ahead, the action oiteach crank on the shaft is' to sweep thesediment which it descends and into the connecti 1 3 this action being greatly facilitated by the port construction just described,whereby any sedimentthat may tend tobe carried across side 15 and deflected downwardly into the sediment chamber 12. Four vertical connctions 13 are provided, one for each ,crank, and the casing section '6 will preferably be provided with tra,

whereby said secti n will be. divided into con ipa-rtinent s, one foreach crank, and each compartment will retain therein a suflicient quantity of oil for the immersion of the crank on its engine is tipped, as for instance, when the vehicle ascends or descends'a hill. 'To lubritherewith, the sediment the port will be intercepted; byfthe 1 n'sv'erse partitions 16,

down stroke even though the e cate by the splash system,-as w'ellas to facilitate the sweeping out of the sediment by the rotation of thecranl rshaft 10, each crank will be provlded withav dipper or -spoon, pi"eferab1y a hollow curved projecscripti on.

tion 17, the projection being curved downwardly in the direction of rotation of the shaft when dri\ ing ahead.

The bottom of the sediment chamber 12 pitches downwardly, preferably from rear point near the front and lower end thereof and above the bottom of'the sediment receptacle. The pipe section 22 projects upwardly within the receptacle 19 and has its upper end threaded, as shownat. 24, and to i this threaded end there is applied a cup 25,

the cup being threaded onto the upper end of the pipe section' lhe'receptacle 19 is provided with a cover 26. i

27 denotes apipe extending from near the bottom of the receptacle 19 toa pump 28, which may be of any ordinary construction, the'shatt of the pump being indicated at29 andbeing' driven in any convenient manner I from the engine shaft. The shaft. is shown as extending into a casing3O in which an enginedriven gear may belocated, arranged to mesh with a suitable gear on the shaft 29. From the pump 28 a pipe 31 extendstoa filtering, washing andcooling tank 32, provided with a suitable gage by means of which the level of oil in said tank may be observed. From this tank there extends a pipe 34 from which project suitablebranches 3o, arranged to dischargeoil into the crank,

case or engine base in positionto strike the ascending cranks. 1

The operation of the illJPtlJTlillS"will be clear from the drawing and foregoing de Thooil to be used in the system ,or apparaltus isinserted'into the receptacle 19 through the filling tube 20, the receptaclc being filled as high as the top of the cup 25.; Thefoil in this receptacle, whethelwfirst, admitted thereto or overflowing frotn'the crankcase and cup 25-is pumped ,into the tank 32,

V where its is washed, purified. and cooled.

lhnlll thidtank it flows through,the header 11]!)6134- and'branches 35, into the engine case. The revolution-of the cranks. together with the projections 17, effectively sweeps auy heavy sediment, thatrmay tend to ac .cumulate in he bottom of-the tank, into the receptacle 12, from which the sediment may be drawn from time to time by the removal of plug 18. The oil will fl w trorrtthe re level of oil in the crank case or engine baseand that, by the adjustment of said cup, the let'el bf the oil in the crank case may be variedhs'desired.

It; will be observed that the oil discharged tfl'u'ough the pipes will strike on the upper-side ofthe connecting rod bearings 11 as the cranks approachtheir upper centers. Part of the oil thus discharged will be thrown by the centrifugal action into the lower end of the cvlinder above each crank, lubricatingrtheinner wall thereof and another portion oi the oil thus discharged will be throunras high as the wrist pin in each piston and will lubricate the same,

lit-he specification and claims, reference isinadeto thou-rank having a projection -(l7). 'By the tcrtn' crank, I do not propose to; be limited to anyspccial part of the .erank shaft or the cooperating portion of the connecting-rod, it being sufficient for the purpo:-:e of my invention that any ofthe parts rotating with the crank shaft be provided with sitcha projection which can dip intfo'thc oil'iorjthc purpose of lubricating by the splash system and at the same time assist .in sweeping out the sediment. i llm iiig thus described my invention, what l t claim is: t t t i I I'l be coinbiinttiona with an engine crank case. of a receptacle comn'umicating with said lease'ainhlnning adjustal'ile means for maintaining the level ot'oil in said case, a ,sedinn' nt receptacle o wratively interposed between theft-rank rase and the former receptacle, a filtering apparatus. means for supplying oil tron' ibe first mentioned receptacleto said apparatus, and supply conneetions 'cxtcuding bct'avecn said apparatus and the crank case.
