AIR AND GAS CLEANER.

- Application filed October v10, 1927. Serial No. 225,282

This invention relates to air and gas clea1i-. ers.

An object of the invention is the provision of a device for cleaning airor gas of foreign matter, in which the gas'or air is directed through a tortuous path while varying the speed of said gas or air.

Another object of the invention is the provision or' an air or gas cleaner for use in connection with carburetors, air compressors, air ventilating systems or gas plants, the air or gas being supplied at above or below atmospheric pressure, and conducted through a tortuous path, part of which contains a bath for not only washing the fluid, but for adding moisture when desired.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawings forming a part of the specification nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define. no material departure from the salient features of the invention as expressed in the appended claims. In the drawings: Figure 1 is a vertical section of the cleaner. Figure 2 is a horizontal section taken along the line 2-2 of Figure 1'.

Figure 3 is a horizontal section taken along the line 33 of Figure 1.

Figure 4 is a fragmentary vertical section of the top of an inner casing of the cleaner.

Referring more particularly to the drawings, 10 designates an outer shell, closed at the bottom 12-and provided with a cover 13 having a central opening lel. An'inlet pipe 15 is received by an annular flange 16, which 40 embraces the openin the flange being socured to the inlet pipe in any approved manner.

A discharge pipe 17 is received within and nearly fits an upstanding tube 18 i'ormed 1ntegrally with the bottom 12 of the shell 10.'

- An inner shell has the upper end closed by acurved top '31,'which is secured to said .shell in any approved-,manner. The inner shellproj'ects above the periphery of the top, and is provided with a plurality of slots 32 for spreading and breaking up aliquid which is sprayed upon the central portion of the top 31 through a nozzle 33. The inner shell is supported from the inner wall of the outer shell by means of I-bars 34, which have the flanges thereof riveted to the inner and outer shells, whereby the inner shell is retained -in spaced relation with the outer shell to form an annular'passage for gases entering the inlet pipe 15. v

The. lower open end of the inner shell has a flared flange 40 'providing'a restricted communication between the inner and outer shells directly above the level of the liquid in the well 21. v

A pipe 41 connects the nozzle 33 with the well 21.

A pump, not shown, is adapted to be connected by means of a T 42 with the pipe 41, between the valves 42 and 43 which are interpolated in the pipe 41. Instead of the pump, the T 42" may be connected with the tanl: at a higher level so that water may be supplied. by gravity. hen valve 42 is closed, an d valve 43 is open the water or other liquid will I flow through the T, pipe 4-1 and thence from the. nozzle 33. Again the valve 42 maybe open while valve 43 is closed when varying moisture is desired, or when it becomes necessary to flush or clean out the well.

In the operation of the device, gases or other fluids are forced or directed through the inlet onto the top 31 of the inner shell, wherein they are spread outwardly toward the annular passage 35 between the inner and outer shells. The gases travel downwardly through said passage and are deflected by the flared flange 40 on to the surface and partly through the liquid in the well 21. they travel upwardly through the annular passage 45. The speed of travel of the gases is accelerated as they pass the flange 10, because of the fact that the reduced space between the flange 40'and the shell 10 acts as a venturi. The gases then enter the discharge Thence pipe 17 .over the upper end oi said pipe, and

are ready for use.

'engine for the'prevention of preignition of the engine cylinders.

As the gases pass through the liquid in the -well', they give 1:p in1purities and foreign matter which are heavier than the gas because of the battling of the gases by the tortuous path. The released impurities fall by gravity to the bottom of the outer shell, and are collecteclin the liquid.

The cover 23 is removed periodically to remove the liquidand the sediment collected therein.

The top 18 has an annular flange 50 seated on a flange 51 of the shell 10 and riveted thereto. A gasket may be'interposed between the flanges to prevent the leakage of gas.

We claim: I

1. A cleaner for fluids comprising an outer shell, an inner shell spaced from and located within the outer shell, the inner shell hriving a closed top, and an open lower end spaced from the bottom of the outer shell, the lower end of the inner shell being flared outwardly 'thereby providing a restricted communica tion between the lower end of the inner shell and outer shell, an inlet pipe connected with the upper end of the outer shell, a discharge pipe projecting into the inner shell, means for spraying a liquid on the top of the inner shell, the outer shell having a well at the lower end to store the liquid in spaced relation with the flared end of the inner shell:

2. A cleaner for fluids comprising an outer shell, an inner shell spaced from and located witlnn the outer shell, the in11er shell having a closed top, and an open lower end spaced from the bottom of the outer shell, the lower end of the inner shell being flared outwardly thereby providing a restricted communication between the lower end of the inner shell and outer shell, an inlet pipe connected with the upper end of the outer shell, a discharge pipe projecting into the inner shell, means for spraying a liquid on the top of the inner shell, the outer shell having a well at the lower end to store the liquid in spaced rela tion with the flared end of the inner shell and means for breaking up the liquid as sai liquid leaves the top of the inner shell.

3. A cleaner for fluids comprising an oute: shell, an inner shell spaced from and locate within the outer shell, the inner shell having a closed top, and an ;open lower end space from the bottom of the outer-shell, the lowe. end of the inner-shell being flared outwardl thereby providinga restricted communica tion between the lower end of the inner shel and outer shell, an inlet pipe connected witl the uppcr end of the outer shell, a-discharg pipe projecting into the inner shell, means to. spraying a liquid on the top of the inner shell the outer shell having a well at the lowe end to store-the liquid in spaced relation wit] the flared end of the inner shell, the inne' shell beingextended above the periphery o the closed top and provided with slots to breaking up the liquid as said liquid leave the top of the inner shell.

4. 'A cleaner for fluids comprising an oute shell, an inner shell spaced from and locate within the.- outer shell, the inner shell having a closed top, and an open lower end space from the bottom of the outer shell, the lowe end of the inner shell being flared 'outwardlj thereby providing arestricted communica tion between the lower end of the inner she] and outer shell, aniinlet pipe connected wit] the upper end of the outer shell, a dischang pipe projecting into the inner shell, mean for spraying a liquid on the top of the inne shell, the outer shell having a well at th lower end to store the liquid in spaced rela tion with the flared end of the inner shell and means for conducting the liquid storm in the well to the spraying means.

5. A cleaner for fluids comprising an oute shell, an inner shell spaced from and locate "fwithin th outer shell, the inner shell havin;

a closed op. and an open lower end space 'from the bottom of the outer shell, the lowe end of the inner shell being flared outwardlj thereby providing a restricted communica tion between the lowerend of the inner she] and. outer shell, an inlet pipe connected witl the upper end of the outer shell, a discharg pipe projecting into the inner shell, the dis charge pipe terminating at the inner en thereof in spaced relation with the closed to; of the inner shell, and means for spraying liquid on the closed top of the inner shell.
