(Cl. 18S- 75) 6 Claims.

This invention relates to a system or .apparatus whereby the lubricating oil in an internal combustion engine will be maintained relatively cool, and that fraction usually lost through evaporation will be saved and used.

More specifically, I aim to provide for the introduction of air with circulating oil returned to `a crank case, and means to separate or remove the oil from the air as it leaves the crank case,

and which feeds such air to the carburetor for .1

Numeral 2B denotes a separator having a cylindrical or other casing provided with a removable cover 26 telescoped in the upper portion thereof with the joints sealed by means of removable gaskets at 2'| and 28.

Gasket 21 is supported on a transverse wall or partition 29 within the casing 25 spaced above another transverse partition or wall 30. Mounted concentrically of the cylinder 25 with its ends spaced from the ends of the casing 25 is a shell orauxiliary cylinder 3|. An annular chamber 32 thus is provided within the cylinder by the parts 25, 29, 39, and 3|, with which the conduits I9 communicate adjacent the top and supply thereto the mixture of air and oil vapor passing from the engine.

The mixture from chamber 32 will pass down'- wardly therefrom through openings or ports 33 in the partition 3D, arranged relatively close to the auxiliary cylinder or shell 3|, when it will be deflected inwardly toward such shell by a depending, inwardly tapering skirt 34 below said partition 33, being directed into an inclined collector 35 whose inner edge is fastened to the y shell 3| The mixture then passes through a series of depending tubes 35 fastened to the shell 3| and communicating with the collector 35 adjacent the base of the latter, the same thus discharging the mixture adjacent the base of the cylinder 25.

A plurality of bell conduits 36, open at the bottom, communicate adjacent vclosed tops with ports or openings 31 in the wall of the auxiliary cylinder 3|, such bell hoods 36 being of U shape in cross-section, .as best shown in Figures 6 and 7, and at their longitudinal edges being soldered or Welded to the periphery of the auxiliary-cylinder 3|. Such bell hoods 36 extend downwardly through and below the collector 35, the latter being welded or soldered to the exterior of the bell hoods 36, so that the oil cannot escape but will pass downwardly through the tubes 35.

Between the base of the cylinder 25 and the lower ends of the bell hoods r36 is a perforated wall or partition 3l', and at the bases ofthe bell hoods 36 a deflector 38 preferably is provided, which is marginally in spaced relation to the wall of the cylinder 25 to permit passage of air downwardly between the same. Thus air or mixture which does not pass into the collector 35 will pass downwardly around the periphery of the dellector 38 and thence upwardly through the bell hoods 36 and ports 3'! into the interior of the auxiliary cylinder 3 Any vapor which passes downwardly through the tubes 35', also will join that air or vapor which ascends through the bell hoods` 36.

A partition or wall 39 is located 'Within the auxiliary cylinder 3| Ibelow the openings 3l, and adjacent the partition 39 outlet ports 43 are provided in a centrally located tube or conduit 4| arranged to drain oil adjacent the base of the cylinder 25 through ports 42 formed in an enlargement 43.

,The auxiliary cylinder 3| will discharge the air and any vapor therein into an upper chambel` 44 provided within the cover or closure 25. An inverted conical collector 45 is located in chamber 44, extending from the central tube 4|, and the latter having receiving openings or ports 46 therein adjacent the base of collector 45 so that oil may drain therefrom into the tube 4|. The upper end of the latter preferably is closed as by means of a cork or any equivalent 4T, to avoid f any ,effect of suction incidental to operation.

The air from the collector 45 will enter the lower end of outlet pipe 22 whose lower end extends into the' receptacle, and which pipe extends through and is soldered or welded to the closure To facilitate the separation of oil from the air, I preferably provide steel wool or any equivalent at different locations, and especially at 48 in the collector 35, at 49 on the perforated plate 31', vat 50 on the partition 39, and at 5| in the collector 45.

Conduits or drain pipes 52 extend from the partition 29 through the "partition 30 to convey pors which normally would be lost are condensed and returned into the oil pan and used.

municating with the second-mentioned collector, said hood means being open at the bottom and extending through the inst-mentioned collector.
