OIL BECTIFIER.

Application tiled September 26, 1925. Seriallo. 58,950.

My said invention relates to oil rectitiers and it is anobject thereof to provide in conjunction 'with the rectifier an improved. construction of this character with a strainer for strainin' particles of foreign matter out of the oil w ich strainer shall be highly effective and capable of use over an extended period of time without becoming clogged.

Referring to the accompanying drawings which are made a. part hereof and on which similar reference characters indicate similar parts,

The single figure is a side elevation of my device in position on an automobile.

.In the drawings reference character 10 indicates the carbureter 'of an internal combustion engine which may be a part of'an automobile, my device b'eing intended primarily for use in automobiles though it is not necessarily limited to such use. A lpipe 11 is .connected to the carbureter at the air intake side of the throttle valve 12 said pipe being centrally connected at its other end to the top of a casing 13 having a distillation chamber surrounded b a 'acket 14 to which exhaust gases are admitte from the exhaust side of the engine by way of passages indicated at 15. The upper part of the chamber constitutes a distillation chamber in which diluted oil is heated so as to vaporize volatile constituents as 0rasoline and water which are then drawn o through the pipe 11 by means of suction from the carbureter. ln previous constructions it has been custoinary to attach the outlet pipe from the rectifier to the intake manifold but this is objectionable for the reason that the suction through said pipe decreases in accordance with increasing speeds of the engine and vice versa. This is exactly the opposite of the result desired since the greater the speed of the engine the more rapidly the oil circulates and a greater suction 1s required to eliminate the impurities. 'ljhe heat in the exhaust of course increases with increasing speed of the engine at theA same time that the flow ot' oil decreases in such earlier constructions and thus there is danger of too much distillation at high speeds and too little distillation at low speeds. The greater the sieed of the engine therefore the more rapid should be the passage of the oil through the rectifier.

Another objection to former practice is that I when idling such connections as above referred to break the vacuum in the intake manifold and cause sensitive engines to miss which is objectionable.

'A pipe 16 is located centrally of the casing 13 said pipe being open at its upper end which is normally closed by a valve 17 seating in the uppervend of the pipe 16. This valve is .opened and closed by means of a oat 19 and when opened admits air to the upper end of the chamber, the air, in this instance being taken from the crank case though the pipe may open directly to the outer air if desired. A Siphon 20 provides means for drawing off the purified oil from the distillation chamber when a suiicient amount has accumulated therein, this siphon leading back to the crankcase or to a suitable reservoir for pure oil. It will be seen that opening of: the valve 17 relieves the partial vacuum in the upper part of the distillation chamber and thus enables the oil to escape with greater rapidity. If desired the parts may be so proportioned that the upper end of valve 17 closes the adjacent end of pipe 11 so as to breakthe suction more effectively by interrupting the communication to the carbureter.

Diluted oil is supplied to a chamber at 21, which chamber in this instance is below the distillation chamber, by means of a high pressure line 22 to which oil is supplied by a pump or other suitable means. 'From the high pressure line the oil passes through a pipe 23 to the chamber 21, and if desired a. by-pass 24 may be provided at an intermediate point to reduce the pressure by carrying oil an excess of oil and prevent too great a supply to the distillation chamber.

The chamber 21 is located below the distillation chamber' partly for the reason that the sediment in the oil is thusgiven a chance to sink to the lower part of the chamber where it can be drawn off through a port normally closed by a screw-plug 25. In the present construction the part of the casing which includes the chamber 21 is se arable from the main casing being connecte thereto by screws 26. A port at the upper end of the chamber 21 is surrounded by an annular lange 27. having an outwardly projecting Between the sediment chamber and the distillation chamber there is an intermediate chamber 28 in which a fabric strainer 29 is arranged for separating the solid 'impurities from the oil. At its lower end the strainer is held in place about the lip on the flange 27 by means of a spring ring or Wire 29. A removable partition 30 is placed at the upper end of the intermediate chamber adjacent the bottom of the distillation chamber and is so held by a spring 33 or in any other convenient way, and this artition is provided with one ormore openings or ports 31 therethrough.

I make the strainer 29 from a substantially cylindrical fabric bag preferably of non-inflammable fabric, as for example asbestos, in order to provide a large area through which the lubricant may pass. Rings 34 and 35 are alternately placed inside and outside of the bagto cause the same to foldyover in Japanesev lantern fashion and when collapsed occupy a relatively small space within the'l chamber.

It will ,be obvious to those skilled in the art that various changes may be made in my device Without departing from the spirit of the invention and therefore I do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
