To all whom it may concern:

Be it known that I, CHARLES E. BaooKs, a citizen of the United States, -residing'in the city of St. Louis and State of Missouri, have invented a new and useful Engine- Oiler, of which the following is a specifica- This invention relates toV oilers for enginesand has for an object the production of a device which operates automatically to lubricate the working parts of an engine.

Another object of the 'invention is to produce a device of the character mentioned. free from moving parts, which is operated lf by the use 'of the pressure and vacuum created in the crank case of the engine by the normal operation of the pistons.

'Io these and other .ends I have designed,

combined and arranged the several parts in' the 4manner hereinafter shown and del scribed, reference being had to the accompanying drawing in which* Figure l is a vertical section through the cylinders and crank caseof an engine in Whichuthe device of the preQent-invent-ion is embodied, Fig. 2 is an end view of an en gine showing a part of the crank case broken away, disclosing a portion of the deviceof the present invention. F ig. 3 is a horizontal sectional view on the line 3-3 of F i l, and F ig. 4 is a ldetailed view of one o the nozzles constituting a portion of the device of the present invention.'

In the embodiment of Arny invention-illustrated ili/the'drawing, the oiling device is shown in connection with a four cylinder engine, .the several cylinders thereof being indicated by A in which are operatively mounted pistons B. The several pistons B are'connected to a crank shaft C by connecting rods D, which with said crank shaft C are housed in a crank case E. The crank shaft C is mounted in bearings formed in the crank case E in the usual manner, and the several pistons B are connected thereto by the connecting rods D in such a manner that the two pistons to the one side will travel downwardly while the two pistons to the other side travel upwardly and vice versa, as the vengine continues to operate. The crank case E is provided with a removable bott-oni or cap 1 which is farranged to be joined to the upper part of the crankV -case 2, which is formed integral with the to form a tight and perfect joint. The crank case E is divided into two chambers and Cr by the vertical partition wall 3, formed integral, with the main engine casting in the upper part of the case 2 and the continua tion partit-ion wall 4 formed in the iower part of the case E. v

The oil chambers H and I are supported by the 'lower part of the removable bottoni or cap l, from which they are separated by a horizontal plate or wall 5. In the einbodinient shown the chambers H and L are formed integral with the lower portion of the crank case E. The` bottom of the chainbers H and I incline towards e center open# ings 6, which are provided with removable plugs 7 for draining the vsaid chambers. Each of the chambers H and I also has at its outer end an opening 8, 4which is closed by a screw plug 9, which plugs may be reopenings l1 inthe plate or wall 5 constitute intercommunicating passages, whereby the oil chamber H is communicated with the chamber G, and the chamber I 1s communi- `cated with the chamber F.

In the upper face of the plate or wall 5, at suitable intervals, are a plurality of threaded orifices into which are screwed: nozzlesv or. oil distributing devices l2, the upper ends of which are inclined so as to direct the oil ejected therefrom toward the s point of the mechanism that it is desired to lubricate. Thus vin F ig. 2 the oileyected lfrom the nozzle is directed toward the wrist pin connecting the piston to the connecting rod, as indicated by the dotted line, and as the parts lnove they are brought into the path of the spray of oil, thus being freely and effectively lubricated at each` reciprocat-ionof the pistons.

In practice the device operates as follows: Either one or both of the chambers II and I are filled with lubricating oil of suitable quality. As the pistons on one side of the partit-ion wall 3 4 move upwardly, those on the opposite side inove downwardly, thereby creating pressure in the chamber in which the pist-ons are moving downwardly and a partial vacuum in the other chamber in which the pistons are moving upwardly. The pressure thus created is con- Idd ias

aaa

. Bepi it al ducted to the oil chamber on the opposite side of the partition `wall 3-4' through the passage lO-ll, thereby ejecting oil through the several nozzles supported above the oil chamber, with sutiicient Jforce to cause a spray or stream of oil to raise from each to the upper portion of! the cylinders above the chamber, thereby throughly lubricating all the interior moving, parts of the engine. Tliejartial vacuum 'cieated in the upper Chamb r, by the upward movement of the pistons, reduces the pressure so that the oil may be ejected more freely by the pressure caused by the de'p essing of the pistons in the opposite cham er. This action will be -repeat-ed als the direction ozt movement of the pistons is changed as the engine continues y to operate', ejecting oil into one side of the engine and then into the other at each stroke of the pistons reciprocating inthe cylinders. The surplus oil discharged from the nozzles, and which is not taken up by the moving parts, recedes to the bottom of the crank case and flows back into the oil chamber on the opposite side ot the partit-ion wall 3-4. It will be apparent that the arrangement ot the device tends to leep the supply of oil. in` the oil chamberstequalized, as the oil `passes from one oil" chamber to the other,

through `the upper chamblers, untilthe level of the oil in both ot the oil chambe'is` is the same. c

The device is automatic in action, eject; ing a predetermined quantity of lubricant, depending upon the size of the opening in the nozzles, at each stroke ot the-pistons. The device is also economical, with respect. to the amount of oil consumed, because all the surplus oil not utilized in lubricating the parts, 4is conducted back to the oil cham!I bers.

l am aware that numerous changes in the details oi? construction may be made without departure from the spirit and scope of my invention. I do not limit myself, theretore, to exact details of construction shown and described7 but that I claim and ters-Patent is:

l. The combination with an engine casing, ota crank case attached thereto, a partition dividing said crank case into separate chambers, a separate oil container below cachot1 desire to secure by Letsaid chambers, a passage leading it'roiireach of said chambers to the oil container below the other of said chambers, and a number of oil distributing devices located between the vertically adjacent chambers and oil containers through which oil is ejected from each of the oil containers into the chamber above' thesame when the engine is in oper ation, substantially as specified.

2. A device of the character described, comprising' a number oit oil containers, an

independent chamber above each of said oil containers, a wall separating said chambers from said` oil containers and a number ot nozzles carried by said wall through which oil is forced when the engine is in operation, substantially as speciied.l v

3. ln an engine, an oil container, oil dis tributing devices leading from said container to the crank case of the engine and a passage for introducing air pressure in said oil container below said` oildistributing devices, substantially as specified. l

4. In an engine, the combination with a number of independent crank cases, of an \oil container mounted-below each of said crank cases, anumber of oil distributing de* vices between each of said' oil containers and the respective vertically adjacent crank case, and intercommunicating assages between the laterally adjacent crank case of one unit and vthe container of the adjacent unitT substantially as specied.

yInl an "engine, the combination with a 'crank caserthetefor, of partition walls positioned vertically in said crank case dividing said crank ease into a number oit independent units, a second partition wall extending horizontally and dividing each unit of said crank case into an upper and lower compartment,a number of oil Ydistributing devices positioned on the upper` face of said horizontal wall, and intercommunicating passages through said vertical and horizontal partition walls leading from the upper chamber et one unit to the lower chamber of the adjacent unit, substantially as specified.

In witness whereof, I have signed this 'specification in the presence of two subscribing witnesses.
