To all whom i mayconectanl 4 Be it known that I', CHARLEsLSCHMmT, a

` citizen of the Republic of France, residing at in perspective.

Cleveland, in the'county of vCuyahoga and State of Chio, have invented a certain new and useful Improvement in Lubricating Systems for .Motor-Cars, of which the following is a full, clear,and exact description. I

The obje'ct of the invention is to so improve the lubricating system O f a motor car that said car ina travel further without the necessity for rep enishingthe oil, and so that the crank cases may be easily and conveniently supplied with the vproper quantity vof oil whenever it is necessary to change the oil therein. d f

The invention consists in the combinations of. par-'ts hereinafter described and `pointed v out definitely in the claims.

In the drawing, Figure 1 is a4 diagrammatic view of the invention,-the' engine casing and the crank cases thereof being shown in side elevation, and the other parts Fig.u 2 is a side, elevation partly in section of a mechanical oiler which forms apart of the invention. Fig. 3 is a sec-` tional side elevation of the valve 'mechanism associated. with the oil storage tank; Figl Iis pair being provided with a crank case, these parts being of familiarconstruction. The casing A contains cylinders 1 and 2, and is. secured over the top of the -crank case B. The casing A contains 'cylindersjS and 4 and is secured over the topof the ciank case B. p

The two crank cases are preferabl formed in a single casting, .as shown. vIt w` be understood, without illustration that the crank shaft is mounted inbearingsin the crank cases. f

`The mechanical oileris, generally speaking, .Of familiar construction; it includes a` tank C, which contains the oil pumps, and the 'operating mechanism therefor. this tank are 'four oil yforcing pumps D, which respeccase .disharges into the two cylinders 1 and 2; 55

pipeE ywhich is branched and discharges into the tWO Cylinders 3 and 4; pipe F2 which discharges int-O certain bearings in the crank and 'che pipe F3 which'discharges into Certain bearilvlgs'in the crank case B. The 60 v tank C also vcointains the main oil pump H Whose function is to ,pump oil from a supply tank "into a `"chainberkil, indicated by dotted lines in Fig. 2, in a casinglb-This Acasing is to be secured on one` side-of tiieuasirboard K, while the tank C issecured to the ctther side thereof.

The tank C contains fami ihr-mechanism for operating the several pump pistons, said mechanism including a shaft M carryin several cams m, which engage with the yo es O 4 l attached to the pump pistons. A beveledv gear n is secured to this shaft in mesh with a beveled gear n on a vertical shaft'M, which y/shaft projects through the bottom `of the tank and 1s connected witha flexible shaft n. which receives its power in any 'suitable Inanner as from vthe crank shaft in casin B.

The chamber J discharges oilsthere'in rop by drop through various valve controlled, 80 ducts y', said dropsfalling through-glass tubes L into pockets t in the bottom of the casin l. vEach of these pockets-is connected wit the inlet side of one ofthe pum s D. Heretofore the tank C has centaine all of the oil available f or use b the mechanical lubricatordescribed. T e capacity of this tank has always been limited so as to requireiilling too frequently to be satisfactory to the car owners. The A'capacity of this tank has 90 been necessarily'li'mited, by the fact that itis secured to the front side of the dash,'where alarger tank cannot be conveniently laced.

This-'valve has a an oi chamber above said oil forcing pumps, perforated tubular stern w which extends l means for delivering regulated quantities of through the top of the tank, aand has an operoil from said chamber to the inlet side of said 80 ating handle w on its upper end and an inpumps, pipes connecting the outlet side ol dex plate X is secured to lthe top-of the tank said pum s with the engine cylinder and beneath this handle. yf bearings in the crank case, an oil storage It is necessary thfat at certain intervals, tank'locatedabove the required. level of' the the oilv in tlie'crfaiik case shall be drawn oli oil in said crank case, a valve controlled pipe 85 apfresli'bil"supplied. The crank cases are connecting said storage tank with`the'crank allways provided with drainage outlets in case, a pipe connecting said storage tank their bottoms; and, heretofore, they have with the inlet side of themain pump, a duct had also some sort of capped inlet opening in connecting the outlet side of said pump with their tops; At best, these latter openings said oil chamber, and means for conducting 90 are iiiconveniently laced, and the putting the overliow from said chamber back into of oil into the crank) cases through them is said storage tank.

With the described construction, the combination of the engines and crank however, one has only to turn valve W by cases, a tank ,containing a main pump and 9b means of its handle, and the required oil, `several oil forcing pumps and operating will low from the storage tank Q into either mechanism therefor, an oil chamber located crank case. -But it is a matter of some imabove said tank, means for delivering reguportance that neither too much nor too little lated quantities of oil from said chamber to oil shall be put into each crank case.

These contrivances for filling crank bearings in the crank cases, an over flow pipe cases and determining when the proper quanleading from said chamber to said tank, an tity of oil haslbeen put in, are inconvenient oil storage tank located in a plane above the 105 and therefore unsatisfactory.
