Application n54 April 11, 1906. Serial No. 12,462. on model.)

To all whom it may concern:

Be it known that I, Aueusr H. FRANKE,

of the city of St. Louis, in theState of Mis-' souri, have invented certain new and useful Improvements in Separators, of which the following .is a full, clear, and exact description reference being had to the accompanying drawings, forming a part hereof.

This invention relates to oil-separators for separating oil from the heavier impurities, water, 8pc. and automatically discharging the excess water through one outlet and also automatically discharging the excess oilthrough another and separate outlet and providing means for withdrawing the impurities that have accumulated on top of the water. This separator is used in connection with an oilfilter.

Figure 1 is a side elevation of my improved separator with parts shown in section. Fig. 2 is a plan view. Fig. 3 is a view taken approximately on the line a a of Fig. 1. Fig. 4 is a detail sectional View of an adjusting de Vice made use ofin carrying out myinvention.

In carrying out this invention I provide a tank 1 of any suit-able construction, and for the said tank I provide a detachable lid 2, the same being provided with an aperture 3.

4 denotes a pipe made use of to convey the mixture of water, dirtyoil,&c.,from anysource,

to the tank, and to the forward end of said pipe is connected a downwardly-pending pipe 5, the same projecting through an aperturein the lid 2 and extending downwardly a suitable distance within the tank 1. 6 indicates a vertical pipe within said tank 1 and projecting downwardly, whose lower opening is near the bottom of said tank 1. This vertical pipe 6 is connected at its upper end to a T-casting 7. Threaded into oneprojection of the casting 7 is a short horizontal water-outlet tube I 8, the same projecting through an aperture in and near the upper extremity of said tank 1. To the outer end of the tube Sis connected a T-casting 9, and threaded into the lower projection of said casting is a vertical pipe 10, the purpose of which is to carry oi the water which is forced out of the lower part of the tank 1 through the said pipe 6 and through the said T-castings 7 9 and outlet-tube 8 by the pressure of the oil riding on top of the water. i 7

ing a suitable distance above the lid 2. The

purpose of said pipe is to aiford means for cleaning out the pipe 6 and also to prevent siphonic action through the said

passages

6, 7, 8, 9, and 10.

' Projecting into the tank 1 on the side opposite from the Water-outlet 8 and at a suitable distance above the level of the said outlet 8 is the oil-outlet tube 12, to the inner end of which is connected an adjusting device 13. Into the lower end of said adjusting device is threaded a nipple 14:, the said nipple being smaller than the vertical. inner portion of the T-casting. This adjusting device 13 and nipple 14 are used for the purpose of raising of lowering the maintained water-level in the said tank 1 by lowering or raising the top edge of said nipple 14, and thereby decreasing or increasing the difference in height between the water-outlet and the oil-outlet levels by forcing the oil to flow up through said nipple 14; over the top of the same and then out through the oil-outlet tube 12. In this manner I arbitrarily bring the water-level even with the outlet-faucet 20 in order to bring the layer of impurities that rides on top of the water in direct communication with the said outlet 20 for the purpose of withdrawing the said 'impurities through the said faucet 20.

The fittings and pipes 15 16 17 18 are for When installing this separator, the tank is first filled with water about three-fourths full, after which the oil and water to be treated are conveyed into the tank through the pipe 4 5, or, if preferred, may be poured directly into said tank through the aperture 3. The water mixed with the oil being the heavier gravitates to the bottom, and the oil being lighter is upheld by the water, as shown in Fig. 1. Every speck of the heavier impurities being separately inclosed by a coat of the oil are thereby made lighter than the water, and these impurities form a layer of slush on top of the water, whence they are withdrawn through the faucet 20. After the oil has reached the oil-outlet all excess amount of water will be forced out by the pressure of the oil throughthe;rpassages fi Z8 9. 10, while: all 9f il W11} O YGFHOW'QYQI' the-topfofi the nipple 14 and pass out through the outlet 5 12 and its connections.
