PUBIFYING APPARATUS FOR LUBRICANTS.

To" allwhom it may concern:

Be it known that I, FRANK R. PERRY, a citizen of the United States, residing at Chicago,'in thecounty of Cook and State of Illinois, have invented certain new and usesigned for purifying oil used in lubricating hydrocarbon engines and the like. It may be mentioned, however, that its use is not limited to lubricants for hydrocarbon engines as the same may be employed WhGT-w ever found applicable. In the lubrication of hydrocarbon engines, in which in most types it is customary to provide a supply of lubricant in the crank case, which is distributed by means of the splash, force feed,

combined force and splash systems, or other arrangements, the lubricant may accumulate water, kerosene, gasolene or the like. This is particularly so at the present time where low grades of hydrocarbons are used for the source of power. My device is intended to purify the lubricant by vaporizing and driving off the volatile particles,

water, kerosene, gasolene or the like, so that the lubricant deteriorates to a less extent.

In this case it is unnecessary to drain the crank case as often as is'now necessary at the present time. The invention has among its objects the production of a device of the kind described that is simple, convenient, durable, compact, efficient and satisfactory for use wherever found applicable. My device may also be employed in connection with the supplying of the hydrocarbon to the engine, thereby obviating the use of the type of vacuum feed commonly used for supplying gas or fuel from the fuel tank to the carbureter. Many other objects and .advantages of the construction herein set forth will be obvious to those skilled in the art to which the same pertains.

To this end my invention consists in the novel construction, arrangement and combination of' parts herein shown and described, and more particularly pointed out in the claims.

In the'drawings, wherein like reference characters indicate like or corresponding parts,

Specification of Letters Patent.

Figure 1 is a sectional view through my improved device illustrating its installaion;

Fig. 2 is a sectional view through the same taken substantially on line 22 of Fig. 1;

Fig. 3 is an enlarged sectional view through the device similar to a portion of Fi 1, showing the valve open;

ig. 4 is a sectional view taken substantially on line 44 of F ig. 5;

Fig. 5 is a sectional view taken substantially on line 5-5 of'Fig. 2; and y Fig. 6 is a perspective view of the valve counter weight and supporting means.

Referring to the drawings, it may be mentioned that the device is shown installed on an internal combustion engine, 1 represent-' ing the crank case of the engine .and 2 the exhaust pipe or the-exhaust manifold; I prefer to employthe exhaust pipe or manifold as a source of heat by means of which the water, gasolene, or kerosene and the like are vaporized and separated from the heavy and less volatile lubricating oil. My device consists of the casing 3 of suitable size,

shape and material, arranged to be secure on the exhaust pipe 2 or the like by means of lthe bolt 4 or equivalent means for the purpose. As shown the casing 3 is formed to fit the exhaust pipe or manifold 2 so that heat is conducted through the wall of the.

casing to heat the contents of chamber A.

secured on the flange 6, packing material'95 10, however, being arranged between the two. Theparts are secured together'by'the screws 8 or equivalent means for the purpose. The above sets forth the preferred method of assembling and securing to-v .100

gether the. parts, but as will be obvious from the further disclosure, this-particular construction is not essential. and the same may be modified as preferred.

Arranged to cooperate with the lower 105 edge of the shell 6 is a valve member 11, the Y cooperating faces on valve 11 and shell 6 being such as to afford a tight fit when the valve is closed. I have shown lugs or parts 12 for guiding the valve, causing it to seat 110 'the cylinders.

necessary, however, to illustrate this in detail, as such construction will be obvious, and. in termingpipe 18 a vacuum or suctionpipe the operation will be readily under a vacuum pipe. The same may be connect-,

ed with a vacuum pump driven by the engine or with the intake manifoldor one of I have. not considered it stood without entering into further detail.

A pipe 19 connects the lower part of the crank case below the normal oil or lubricant level with'the chamber B, it being under- .stood that any-particular pipe fittings and the like may be employed-for the pur ose.

A vent opening or port 20-is provide for chamber'A, and in the construction shown I form the opening 20 throughthe' cover 7 flange ,6 and part1, and the intermediate into chamber B, is a duct, as shown a pipe j' packing or gaskets. Extending from adja} cent the bottom of chamber A and opening 21-, 22 'being theport communicating with the chamber B. I also provide 5 a pipe 23 projecting into the chamber A at" the desired distance above the bottom thereof,

which pipe "is connected to the crank case 1 by means of the piping 24 and suitable "fittings or the equivalents for the purpose. I

also provide a pipe 25 in some cases, in communication with chamber B, the purpose of this pipe is to provide a vacuum in a fuel receptacle or auxiliary tank, whereby gasolene may be periodically drawn from the fuel tank to the auxiliary tank and then fed by gravity to the carbureter. vWhere such feed is not desired, as for example, in the case Where the fuel tank is under the cowl in'an automobile or above the engine, pipe 25 is unnecessary and the same may be omitted and its opening in-the closure 7 plugged up. Obviously valves or their equivalent maybe arranged as shown or as desired, valve 28 in. pipe 18, valve 26 in pipe 19, valve 27 in pipe 24, valve 29 at vent '20, valve 30 at port 22, so that the several passageiz may be restricted or controlled as de-- sire consisting of the casing 31 and and inner casing 32, forming chambers 33' and 34, communication between the 'two being through pipe or port 35, at'the'end of which may be arranged valve 36. A vent 37 is also provided and a fuel intake pipe 38, 40

being the fuel discharge pipe connected i may be provided if desired.

The operation of the device may be briefly' described as follows :----Assuming that the parts are in the positions shown in Fig. 1 and the engine not running- As the engine is driven a vacuum" .is formed in pipe 18 and in chamber B, and the oil is drawn up through pipe 19 and discharged in chamber B. An oil in chamber A above I the lower end of pipe 21 and below the up.- per end of pipe 23 will also be drawn up into chamber B. I Obviously air can, enter port 20 to replace ,the-oil drawn out of, chamber A through pipe 2-1.

the oil in chamber A has been drawn up into pipe 21 and the vacuum in chamber B is .broken,-the re being. atmospheric pressure in: both chambers A'andB. This being the case the weight of'the oil in chamber B overcomesthe'wei'ght.16,-valve 11 opens and the contents' of chamber B are' discharged into chamber A." A portion of the same will immediately flow through pipe 23 back to the crank casin As soon, however, as the chamber Bjis emptied or perhaps slightly before, thegcounter "weight, 16 .will closevalve 11 and the operation of the device will be repeated. In this manner oil is circulated from the crank case through m paratus and back to the crank case,

and the more volatile constituents orimpurities, such as water, gasolene, kerosene and the like, are vaporized and driven off device the lubricant is gradually warmed As soon as apow-. -.ever, the oil is heated by the exhaust pipe'2 chamber B air in chamber A passes through I up and kept warm, and consequentlyis more efliciently circulated or splashed in the lubrication of the moving parts'of the engine. Y

In case it is desired to bring the fuel from the fuel tank to the carbureter, pipe 25 is provided and connected to a suitable receptacle, which receptacle is connected to the fuel'tank and to the carbnreter. A vacuum 1 I .being periodically formed in chamber B it In Fig. 1, I have shown substantlally dia-' grammatically a fuel feeding receptacle is likewise formed in the receptacle, and the fuel 1s thereby drawn into the receptacle and thence fed by gravity to the carbureter.

The so called vacuum tank or receptacle The operation of the fuel receptacle or tank 31-32 will be obvious. A vacuum being created in chamber 34, "fuel flows through pipe -38 into the receptacle, the vacuum at the same timecausing the valve 36 to be maintained closed. As soon as the vacuum is broken in pipe 25, however, the

contents of chamber 34 are discharged into chamber 33 and may flow to the carbureter. As soon as a vacuum is created again valve 36 is closed and more fuel is drawn into the chamber 34 from the 'fuel storage tank.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from-the "spirit of my invention,

hence I do not wish to be understood. as.

limiting myselfto the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is 1. Ina device of the kind described and in combination, a receptacle, a vacuum pipe and a supply pipe connected therewith, a

second receptacle below the level of the first, a valve controlling the flow of fluid from the first receptacle to the second, an air duct connecting the two receptacles from a point above the bottom of the first to a point below the top'of the .second receptacle, a drain duct arranged to conduct fluid from the second receptacle, said second receptaclebeing provided with an air duct communicating near the top thereof.
