all the parts desired. Such a system works. satisfactorily if the ool is of the proper depth, but the quantltyof oil delivered by the splash necessarily varies with the variation of depth to which the cranks enter into the pool so that when the pool is too shallow an insuiiicient amount of oil is s lashed and when the pool is too deep too muc oil is used. 'In automobile construction, there is a further diiliculty in that the cha-nge of level of the` roads over which the machine is run necessarily makes a change in the position of the oil pool with relation to the crank shaft. in automobiles having multiple power cylinders arranged d iiiiculty ecornes very great, so much so that in climbing hills the forward c lindergets no oil at` all, While the 'rear cylinder gets too much, and this condition is reversed in going il' down hill f The object of my vinvention is to provide means by which all of the advantages of a splash system may be retained, and the disadvantages thereof be eliminated.

A further object of my invention is to so construct the parts as to insure a sufficiently low temperature of the oiling chamber so as to revent charring of the oil. y

he accompanying drawings illustrate my invention as applied to* a four-cylinder internal combustion engine;

Figure 1 is a side elevation Fig. a sectional-plan on line 2 2 of Fig. 4; Fig. 3 a section online 3 3 or" Fig. 2; Fig. 4 a section on line 4 4 of Fig. 2; Fig. 5 an enlarged vertical section on part of line 4 4 of Fig. 2, Fig.V 6 an enlarged .horizontal section oi the parts shown in Fig. .3; and Fig. 7, a diagrammatic bodying my invention. n

in the drawings, 1() indicates a crank shaft provided with la plurality of cranks 'l 1 The parallel with the line of travel, this' formed in the casting 13. The main body of this casting 13 is provided on its under side andacross its interior with transverse'arrns 14 which carrythe journal bearings. Each of its bearing 12 witha pair of upright iian es 15 which thus form an-.cil basin 16, and t is basin is connected by a air of passages17 with a channel 18 out in gli of the bearing 12, and extending out to its ends so as'to communicate withthe sides of the arms of the cranks 11. Formed in the an opening 19 which registers with a riser passage 20 Jformed in the cover 13 which closes the lower end of the casting 13. The

from a header passage 31 which exten s longitudinally through the cover i3', and com municates at one end with the dischar e port 32 of afsniall rotary pump 33 detacha ly seshaft 10. The inlet port 35 of the pump 32 lies within an oil reservoir 36 formed in the cover 13, and leading toward this basin is a channel 37 into which channel lead openings 38 formed in the bottom of .the cover 13 4preferably below each of the hearings 12 provided with an-accompanyingoil basin 16.

in operation, the oil collects inthe reser- .voir 36 and the depth can be readily seen through the glass 40. At no time .will the oil rise enough to permit any one oi the cranks 11 to dip into it, but as the engine is operatedA and its crank shaft rotated, the pump 33 will be driven so as to draw oil from the reservoir 36 and dischar e it into the header 31, and forward throng the several risersz() into ,thev several basins 16.y rl"he oil flows then from. these basins through the passages 17 and out' through the connecting channel 18 so as to {iow in a stead .stream to the sidesioi the crank arms. along these lines, and is thrown in the same manner as oil is thrown in the ordinaryi spl ash system so as to iill the chamber formed i by the main body 13 and the cover 13, with an oil vapor which thoroughly luhricates all l the parts, including the engine pistons. B

l properly gearing the pump 33 with the cran r l shaft, the flow of oil to the cranks will at all shaft 10 is jonrnaled in suitable bearings 12I cured to one end of thecover 13 and corni. nected by a suitable driving train 34 with a F `he oil then flows outward of thesecross arms 1a is provided at one side e wearing surface bottom of the basin 16 near its outer end is several riser passages 20 extend u weird`Y times be in exact and proper proportion to the speed, and hence to the amount of oilxiequired, and the amount of oil in tlie\reser'`, engine will haverno,

voir or 'the level oi' the ell'ect whatever 'upon the degree of lubriea` tion, and all o'l`v the parts needing lubrication will be unii'ormly lubricated even when the oil in the reservoir roaches its lowest possible level.

I have 'ound'in practice that it is exceedingly desirable that the chamber within which' this oiling takes place be kept as cool as possible, and I accomplish the necessary cooling in the followin r manner: In order to support the construction already described in themain frame of the carriage, I provide the main casting 13 with transverse arms 41 which at their ends are provided with means forattachrnent to the side bars 42 oi' the main frame of the carriage 50. These arms 41 are hollow and communicate with the interior of the main body 13. Each arm is then provided with an opening to the interior, the forward arms having inlet openings 43 and the rear arms having outlet openings 44, each of said openings being protected by. suitable screenings 45. Extending upwardly and forwardly over the Jforward openings 43 are shields 46 and extending upwardly and rearwardly from the rear openings 44 are similar shields 47, the arrangement being such that, as the carriage nieves forward air will be caught by the forwardly extending' shields 46 and forced downwardly through the openings 43 thence through the hollow arms 41 into the interior of body 13 and cover 13', thence rearwardly out through the rear arms 41 and the outlet openings 44. The movement of the air through the casting is facilitated by reason of the suction created by the arrangement of shields 47.

In order to insure a suihcient supply of oil for the crank wrist pins I forni opposite each crank a vertical passage 5U which communicates with the header passage 31. Inthe upper end of each of these passages I insert a short pipe 51 lthe end of which is bent over and directed toward the path of movement of the crank so that a continuous small stream of oil is directed into said path of movement.

I claim as my invention:

1. The combination, with Va crank shaft having a pair of journals one adjacent each' lcrank arm and a cylinder and piston ar- VJfor directing air therethrough,

shaft having journals journaled in said bear- 7 5 ranged in tion of each crank, of suitable bearings ior said journals, an open oil basin arranged adj 'uni each journal and'l having oil passages leading therefrom to the journal and to points adjacent the crank arms, a reservoir to rooe ceive surplus oil, and a pump adapted to carry the oil *from said reservoir to the oil basins, whereby a suilicient quantity' of oil is delivered to tho arms oi the crank to llo` outward along thrown therefrom upon he rotation of the crank shaft.

The combination, with an automobile and an engine carried thereby and consisting in part 'of a suitable inclosing casing having 7;

journal bearings in its interior, and having an air inlet opening at one end and an air outlet opening at the other, together with means of a crank ings, means for supplying a stream o'foil to the arms of the crank in such quantity that the oil will be caused by the rotation of the. shaft to flow outwardly along the crank arms and be thrown. therefrom, of the casing and air openings being such to permit a cooling current oi 'air through the'.-I casing during transportation of the ,struc-1 ture.

In an automobile, the combination-with a carriage, of an engine carried thereby and consisting in part of a main hollow body carry ing in its interior suitable vcrankshaft journal bearings, an open oil basin arranged adjacent the ends of the bearing, and a reservoirto gre 9o ceive surplus oil, andvsaid -I'nain casing being rovided with an air inlet at one end and an g air outlet at the otherfwhereby a current of air will be forced throughthe casing during transportation of the structure', a pump e5' adapted to carry oil from the reservoir to the oil basins, and a crank shaft journaledfin the I bearings, all substantially4 asand for the purpose set forth.

In witness whereof, I', have hereunto set my i oo hand and seal at Indianapolis, Indiana, this 20th day of December, AI, Dh'one thousand nine lhundred and four.
