Application filed December 8, 1920. Serial No. 428,554.

To all 'IIIIOIN it may concern:

Be it known that I, ALFRED R. GIFFIN, a citizen of the United States, residing at Cleveland. in the county of ("uyahoga and State of Ohio, have invented certain new and useful Improvements in Oil Purifiers, of which the following is a specification.

'lhis inventionlrelates to gasoline, paraffin, coal oil. and crude oil purifiers, the principal object of which is the purification of such oils as may be passed through it.

Another object of theinvention is to raise the actual s'pecific gravity of various oils, which are passed through it.

Another object of the invention is to proride a purifier which may be utilized and attached to any style of internal combustion engine.

Another object of the invention is to provide a purifier which eliminates the deposit of carbon which is usually found on the internal parts of internal combustion engines.

Another object of the invention is to eliminate carburetor and spark plug troubles. by removing such elements as carbon and other impurities in the fuel being used before said fuel reaches these specific parts of the engine.

Another object of the invention is to promote a general better running condition for the entire engine.

Another object of the invention is to provide a gas purifier or filter, which will auto-- matically deliver more thermal units of heat energy, from a specific quantity of fuel, thereby increasing mileage w en applied to mobile engines or more actual horsepower when utilized for stationary engines,

Another object of the invention is to provide a purifier for internal combustion engines which will reduce the actual fuel consumption.

Another object of the invention is to provide a purifier of gas producing liquids, which is simple in construction, efiicient in operation and one which can be manufactured and placed upon the market at a minimum cost.

The invention also consists in certain other features of construction, to be hereinafter fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claim. v

In describing my invention in detail, reference will be had to the accompanying the cover removed.

Referring to these drawings, 1 is a metal.

strap, one end of which is threaded and screwed into the cap 2 and securely locked in position by the lock ring or nut 3.

It will be noted that the strap 1 is a straight fiat piece of metal, which may be drilled and bent up to conform to theposition in which it is most desired to retain the purifier. The cap has an inner stem 18 pro- 'vided with a shoulder 4 which acts as a retaining member for the upper screen. 13 (Figure 2) when cap 2 is screwed into closed position and the butt end shoulder 5 on the stem acts as a retaining member for the lower screen 12 Figure 2. 6 is a suitable gas proo'f gasket placed between the shoulder on the cover 2 and the upper edge of the bowl 7.

The bowl 7 forms the containing element for the whole. It will be noted that the bowl element 7 has a bottom in the form of a specific parabola, which is so constructed that it forms an irregular ellipse with the lines taken by the parabola of the

screen members

12 and 13 which is requisite, and most necessary in the correct functioning of said members as hereinafter described.

8 is the inlet port or pipe connection which constitutes the entrance point for the liquid fuel, said ort 8 being placed at a. specific angle, con orming to an imagine. central line drawn from the center of a ho e in said port or inlet 8 to the center of the parabola of the 'lower screen 12 and striking said screen at the contact point of shoulder 5 when in position and locked against the center of screen 12.

9 is a plug which is screwed into the botton of the parabolic bowl 7 said plug having a gas tight washer 1O placed between it and the bowl, said plug 9 having a hollow space 11 which forms-a. well or sediment zone, into which the impurities settle and there stay, until said member 9 is unscrewed and cleaned out.

12 is the lower parabolic screen which it will be noted in Figure 3 is'composed of a screen fabric the mesh of which runs preferably about fourteen thousand' spaces to the square inch. 7

13 is the upper parabolic screen which runs about fifty-seven thousand spaces to the square inch or two hundred forty standard mesh, which mesh is the approximate density of chamois skin leathers 14 is the outlet port or pipe connectlon through which the liquid fuel passes into the carburetor (not shown) after having passed through the screening process.

15 and 16 are retaining shoulders upon which the

screen members

12 and 13 rest and to which they are securely locked, when the cap or lid 2 is screwed into place, bring-' ing the contact pole 18 on lid into'contact and exerting downward pressure on the convex surface of the parabola; of the

screens

12 and 13 by the shoulder membe 4 and 5 on pin 18 said downward pressure having a tendency to increase the outer diameter of the

screens

12 and 13 and thereby securely locking said screens, against and down upon the shoulders 15 and 1 It will be noted, upper screen 13 has a hole 17 to allow for passage of pin 18 when placed in the locked position.

It is an established fact, that the screen 12 will stop normal partices of foreign matter from passing, and that the fine screen 13 will allow gasoline and liquid fuel of similar specific gravity to pass, but will not allow water to pass.

It is also desired to be pointed out that the normal pressure on said liquid fuels, will be approximately three (3) pounds to the square inch, or more in high pressure feed systems where even smaller mesh screens may be utilized.

It may be noted that the container 7 ma v have additional screens, several inlets and outlets, etc. It may also be noted. that the plug and sediment well 9, may have greater length and also have a glass tube inset thereto, to make said sediment visible if so desired. The parabolic shape of the bowl 7 will allow the sediment to settle in the center or ical means for retaining said screens in position.

It will be'noted that the oil is introduced at an angle and in explanation thereof will say that the oil, or current, or pressure is shot upward to the center of the screen, and

whatever back pressure takes place cause said oils to sweep the screens clean from the center of the point Where the stem 18 blocks the screen, the gas then flowing down the sides of the container, washing the sediment ofi the bottom toward the center and into the cup receptacle.

1 claim as my invention:

A liquid purifier comprising a cup-shaped casing having an inlet at the bottom and an outlet at the top, and upper and lower shoulders extending around the inside of the casing, upper and lower inverted cup-shaped screens in said casing, the edges of said screens resting on said shoulders respectively, and a cover on the casing having a dependin stud with its lower end extending through a hole in the upper screen and pressing upon the lower screen and a shoulder on the stud pressing upon the upper screen, whereby said screens are expanded to close contact with the shoulders.

In testimony whereoflI do afiix my signature in presence of two witnesses.

ALFRED R. GI'FFIN.
