ENGINE-BASE OIL FEEDER.

Application filed May 11,

Z '0 all whom it may concern:

Be it known that I, LIONEL TREMBLAY, a subject of the King of Great Britain, and residing at 549 Grand Trunk Street,

in the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented a new and useful Engine- Base Oil Feeder, of which the following is the specification.

The invention relates to an engine base oil feeder, as described in the present specification and shown in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features pointed out broadly and specifically in the claims for'novelty following a description containing an explanation-in detail of an acceptable form of the inven- The objects of the invention are to insure a constant and even supply of oil in the base of gasoline engines by automatic feeding mechanism; to account for the different positions of the engine base and feed 26 walls due to hills in the line of travel of a motor car; and generally to provide an effloat.

Figure 8 is a sectional detail of the cover of the feed well connected to the tank.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the engine base 1 is formed with the central threaded inlet 2 through the bottom thereof into which is screwed the three way union 3.

The pipes 4 and 5 lead upwardly from the union 3 in a slanting direction and are inserted in the feed wells 6 and 7 in the bottom outlets 8 and 9.

Figure 7 is a perspective detail of the 1923. Serial No. 638,418.

-6 and the central guide post 17' extends upwardly from the bottom of the feed well 7, a float 18 being slidably mounted on the post 16 and a float 19 being 'slidably mounted onthepost-l'lfi" g In the 'feed well 6 thefloat stem 20' is screwed intothe float 18 in the'postorifice 2land' is -pivotally joined to the valve stem22.

The float stem 24- is screwed into the float 19 in the post orifice 25 and is pivotally joined to' the valve stem 26,

The cover 27 of the feed well 6 is formed with the central threaded vent orifice 28 into which the bent pipe 29 is screwed and held by the nuts 30.

The boss 31 projects from the inner side of the cover 27 and is bored toform a cylindrical chamber for the cylinder valve 32, which is closed at the ends and has the inlet port 33 adapted to register with the inlet port '34 in the chamber wall, and the outlet port 35 adapted to register with the outlet port.36 in the chamber wall leading to the interior of the feed well 6. The inlet port 34 forms a passage through the boss 31 and cover 27 and is threaded towards the outer end and the'nipple 37 is screwed into the passage for the purpose of connecting the valve 32 by means of the pipe 38 with the feed well 7.

The feed 7 is closed .in by 'the cover 39 having the central threaded vent orifice 40 and carrying the curved vent pipe 41 screwed into said orifice 40.

The boss 42 projects inwardly from the cover 7 and is bored to form a valve chamher for the cylinder valve 43, the latter having the inlet port 44 adapted to register with the inlet port and passage 45 through the 105 boss 42 and cover 39 and the outlet port 46 adapted to register with the port and passage 47 through the boss 42 and cover 39 and parallel with the port and passage 45, said valve 43 being closed at the ends and 110 forminga passage between ports in the flow of oil process.

The nipple 49 is screwed into the passage 4=7 and are pipe 38 secured insaid nipple 49, thereby connecting the feed well 7to the feed well 6.

The nipple 50 is screwed into'the passage 45 and this nipple is connected by the pipe- 51 to the tank 52 thus completing a feed con-- nectionthroug h from the oil tank 52 tothe feed. well 6 thrc ughthepipes and cylinder valve being controlledby the floats in the feed wells.

The ste m is screwed into the cylinder valve, 32 andfoperated-in a suitable slot in the wall bf the j valve chamberand t the 1 stem 22 is screwedfintothe cylinder valve/t3 and operates in a suitable slot in the wall of ae the valvechambert ill his e e n tha bqth yl nd valves. -are..rlgn'gatt d by the; rise and fall of the floats and in the, operation of the feeding-device theoil; inrthe engine .base 1 is. maintained at the same level as-thepredete m dhigl te a ki on other i the aceqr ding to .thegroadg that thel. .motorvehicle is traveling on.

vice, as in going up hill oneyfeed well will maintain the :oil level in, the baseand in goingdowal hillth e. other feed well will main-tainathe level, while on the level road tank is connected, but the float in well 6 is up and cuts olfthefieedtlaere, however no matter. which. well is up, should the level fall below a mean level snfficient forlubrication, then. the tank will be connected .to

.thefeedwell figthroug-hthe cylinder valve in the feed Well 7 and theoil .will;,continue to flow in until the proper level is reached and on the level ground thepredetermined quantity or maximum,will-again. flow in through the same connection.
