OIL CLEANER Filed June 20 /9 z/zo Patented Aug. 28, 1934 uurreosrmres PATENT OFFICE This invention relates to improvements in oil cleaning devices and pertains particularly to a device which is designed primarily for use upon motor vehicles for cleaning the lubricating oil .5 thereof. v a

The primary object of the present invention is to provide an efiicient oil cleaner which is designed foruse in place of the present oil fllteror strainer which is commonly employed on.motor vehicles. V

Another object of. the invention is t provide an oil i cleaning device. which operates through centrifugal action to separate heavy. particles from lubricating or other oil andincludes a sedi-. mentation chamber inwhich the particlesare deposited.

A still further object of the inventiontis toprovide an oil cleaner which is divided into two sections, into one of which oil is discharged in'amanner to constantly keep it in a whirling'cona dition, while in the other part the oil is static and the particles separatedby centrifugal action, settle by gravity therein.

Still another object of the invention is to providel an oil cleaner which will-make use of the settlement by gravity, of impurities in the oil when the oil is not being circulated'therethrough, to trap such impurities andprevent their returning into circulation.

The invention will be'best understoodfrom a consideration of'the following detailed description taken in connectionwith the accompanying drawing forming partof this specification; with the understanding, however, that the invention is not confined to any strict'conformity with the showing of the drawing but may becl ianged or modified so longas such changes onmodiflcations mark no material departure from the salient features of the invention as expressed the appended claims.

of the device. l Y

Referring now more particularly to the draw.- ing .wherein likenumeralsof reference indicate corresponding. parts throughout the several .views, the numeral-1 indicatesa receptacle .wh'ichis preferably of; circular cross. section and having theclosed bottom 2. The wall of the receptacle atthe top is turned outwardly to. form the flange 3 and a cover 4'is removably placed over the open top of the .receptacle and overlies the flange 3 in the manner illustrated.

For the purpose of mounting the receptacle 1 in upright position upon a suitable supportthere is provided. the bracket 5 which is provided with the rightangled portion 6 which has a central .aperture 7 formed therethrough which is of a diameter correspondingto the diameter-of the receptacle 1. Around the. opening or aperture '7 an annular series or bolt-holes 8 is formed for the reception of bolts 9. The. head 4 of the device positions againstthe under side of the horizontal portion 6 of the supporting bracket and is provided. with a plurality of apertures which align with'correspondingapertures in the flange. 3 and which are also .aligned with the holes 8 so that the bolts 9 may; pass downwardly therethrough" to engage in threaded apertures in a ring 10 which surrounds thereceptacle l and bears against the underside oftheflange 3. A suitable gasket 11 is interposed between the'flange 3' andithe'head 4 to; prevent leakage.

The central part of the head'4is provided with the outwardly pressed oflf-set 12 which is centrally apertured and a second outwardly pressed off-I set isformed at 13 adjacent the side of thehead. This second off set portion is also centrally apertured. Extending through the aperture in the portion 12 is. an internally threaded nipple 14 which is flanged for. contact with the'top of the headandwhich receives upon itsinner end the retaininggring15 which is suitably secured thereto.

Surrounding theretaining. ring 15 is a collar 16 whichhasan inturnedportion which is held by the collar. against the head 4 and secured in this collar is a radially slotted disk 17' Which'has the portionshetween the slots turned slightly to form blades, the purpose of which will be hereinafter 18, the'outer end of which is suitably shouldered to engage the top of the head while the inner'end receives a retaining ring 19, against the inner. face oIfWhich is secured a disk'20 which is pressed to form the channel 21 which extends radially from. the center otthe disk to the edge thereof. This channel 21 isdirected tangentially of the receptacle wall so that oil injected thereinto through the nipple 18 will be discharged against the wall in such a manner as to create .a whirling movementin the body. ofoil with which the rein the area between this cylinder and the wall' of ing 24.

ceptacle is filled. The blades of the circulating vein 17 are so inclined that they have their lower Substantially centrally of the receptacle 1 there is disposed the inverted frusto-conical plate 22, 1

the center of which is provided with an opening 23 and as the overall diameter of the plate is less than the interior diameter of the receptacle an opening 24 is formed around the edge thereof.

Beneath the plate 22 and-concentric with' the receptacle, is a cylinder 25 and disposed vertically the receptacle is a plurality of bafiie plates each of which is indicated by the numeral 26 and each of which extends from the bottom 2 of the re ceptacle to the under side of the plate. I. Disposed beneath the plate 22 and in spaced relation therewith, is the flat annulus 27 which has its outer. edge in contact with the wall of the, receptacle. This annulus is set in suitable slots in the baiiles and lies directly beneath the open:

Within the cylinder 25 is a plurality of battle walls 28 each of which extends from the wall of the cylinder 25 inwardly and joins with the'other at the common center. I In operation, the inlet oil pipe is connected with the nipple 18 while the outlet is, connected with the nipple 14 andthe oil or other fluid enters the upper part of the receptacle above the'plate 22 tangentially through the actiorrof the channel 21. v The receptacle 1 is filled with the fluid to be cleaned and the entering oil therefore sets up a circulatory movement of the portion of the fluid lying above the plate 22. As thismovement of the fluid is against the lower edges of the blades of the circulating vein 17, as previously described, these blades will increase the whirling moven1ent of the fluid and'assist in carrying the fluid off through the outlet 14 without hindering the, motion of the body as a whole Due to the plate 22 and the

baffle walls

26 and 28 therebeneath, the fluid below the plate 22 will remain stationary and any heavy sediment in the upper fluid will be worked toward the wall ofthe receptacle and will move downwardly through the opening 24 into the lower outer chamber of which the baffle walls 26 .form a part. The other lighter sediment will collect in the eddy formed at the center of the moving'body of fluid and gradually settle onto the plate 22passingthere-Y through by way of the opening 23 and into the 1 quiescent fluid within the cylinder 25. The bailie From the-foregoing it will be readily apparent that'a device of the character herein 'setforth will efliciently operate to remove sediment from oils or other fluids, wherein the removal of suchsedi mentis desirable, and sinceno filters or strainers are employed the device will operate eificiently over a long period of time withoutattention.
