OIL CLEANING AND PURIFYING DEVICE Irwin F. Kingston, Iron, Minn.

Application August 19, 1939, Serial No. 291,078

(Cl. ZIO-134) 2 Claims.

This invention relates to the reclaiming of used motor oils and pertains particularly to a mechanisrn or device by means of which such oil mal7 be cleansed or reclaimed for further use.

The present invention has for its primary object to provide a novel, preferably portable, oil cleansing or purifying device which is so constructed that it requires no attention for operation after the oil which is to be cleansed or purified is poured into it, the construction and arrangement of the parts of the device being such that the oil will ultimately collect in a cleansed and pure condition in a part of the device from which it may be withdrawn as needed for further use.

Another object of the invention is to provide a novel oil cleansing and purifying device wherein use is made of both upow and downiiow of the oil in the device whereby solid particles will first be extracted or removed by gravity before the oil passes along the upow path through a lter unit and gravitational action will be employed for effecting the passage of the oil along the downow path through a second filter battery.

A further object of the invention is to provide a device of the character described which is of relatively simple construction and which may, therefore, be easily and economically made and in which the oil strainers or lters are readily accessible for removalvto be cleaned or repaired as may be necessary.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not to be confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Fig. 1 is a vertical section through the device embodying the present invention.

Fig. 2 is a sectional view on the line 2 2 of Fig. 1.

Referring now more particularly to the drawing, the device embodying the present invention consists primarily of a vertically arranged preferably cylindrical body which is indicated generally by the numeral I and which is formed in two sections 2 and 3 which rest one upon the other, each of said sections in effect forming an individual receptacle or oil chamber. The upper receptacle or section has a bottom wall 4 while the lower section or receptacle has the bottom wall 5 and when the sections are placed together one upon the other, the bottom wall 4 of the upper receptacle forms a closure for the lower receptacle.

The two sections or the two receptacles are tightly secured together, the upper edge of the lower receptacle being provided with a series of outwardly turned slotted ears 6 while the lower part of the upper receptacle 2 has pivotally attached thereto a series of bolts 'I which are designed to swing downwardly into the slotted ears S and to receive wing nuts 8 so as to lock the two sections of the device together.

The upper section or receptacle 2 has disposed vertically therein the oil receiving cylinder 9, the lower end of which rests upon the bottom 4 while the upper end extends through the open top of the upper section and a substantial distance above the same as shown. The lower end of' the cylinder 9 is provided with discharge ports Ill.

A closure of `any suitable type is placed over the top of the section 2 as indicated at II, having a central opening through which the oil receiving cylinder projects and there is secured to the upper part of the section 2 a handle or bail I2 by means of which the transporting of the purifying device is facilitated.

Disposed horizontally in the central part of the upper section 2 are oil straining units which comprise spaced apertured plates or separators I3 between which is held a strainer material which is preferably formed of burlap and eX- celsior, indicated by the numeral I4, and the separators I3 are in the form of annular steel plates through the centers of which the oil cylinder 9 extends, and these plates are provided with a series of small apertures I5 through which the oil may pass.

The lower receptacle 3 is likewise provided with oil strainer units but these units are made up of the spaced metal disks I6 between which are packed burlap and excelsior filtering material, as indicated at Il, the disks IE being provided throughout with small apertures through which the oil may pass downwardly.

Extending from the upper receptacle 2 above the strainer or filter units, is a pipe I8 which leads downwardly exteriorly of the purifying device and passes into the upper part of the lower section 3 above the ltering units therein, this pipe having the portion lying Within the section 3 provided with a plurality of oil discharge apertures IS.

The lower part of the upper receptacle is provided with a drain cock 20 and the lower part of the lower receptacle is provided with a similar drain cock 2| through which the purified oil may be drawn off Yfrom beneath the lower receptacle filtering units.

In the use of the present oil purifier, the oil which is to be reclaimed or purified is poured into the upper endof the receiving cylinder 55 and discharges into the lower part of the upper receptacle 2 through the openings lll beneath the upper receptacle iiltering units.A As the upper receptacle is filled, the oil will force its way upwardly through the filtering units therein and will escape from the upper receptacle into the pipe l and iiow into the upper part ofthe -lower receptacle, being discharged through the pipe apertures i9 onto the top of the filtering units in the lower receptacle. .From here it 4willilow bygravity through the filtering units into the hottompart of the lower receptacle where it will bezin cleaned and puriiied condition ready for further use. It will be apparent that in the upper receptaclerthewater .and gasoline will settle rom the oil as well as any other foreign matter of a Vsolid nature and such waste or impurities may be dra-wn throughithe `discharge cock 223. The partly puried oilwill then be further puriiied .by its vpassage Ythrough the upper and lower the Aplates i may be easily removed for cleaning'or replacement. ,It `is preferred that these strainers be made up of alternate layers ofburlap and Vexcelsior as shown in the gure, stitched or sewn together in-a suitable manner so that they may be -readilyplaced in position between the perforated plates.

By forming the end portion of the pipe l Vvwhich lies within the lower receptacle 3, with its inner-end closed and with apertures through the wall thereof, it will be readily apparentthat the oil as it is discharged into the lower receptacle will be. distributed over-'the iiltering unit.

What is claimed is:

l. -An -oil purifier, comprising a pair of receptacles each having a bottom and side wall, one of said receptacles being disposed upon the other whereby the bottom wall of the upper receptacle forms a closing top wall for the lower receptacle, a vertically disposed cylinder in the upper receptacle supported upon the bottom Wall thereof and having an outlet aperture at its lower end, the upper end of the cylinder being opened for the reception of oil, a horizontally disposed filtering unit vencircling said cylinder above said outlet aperture and dividing the upper receptacle into upper and lower oil receiving spaces, the bottom outlet of said cylinder opening into the lower one of the spaces, a ltering .Unit horizontally dividing the lower receptacle anddividing the same into upper and lower oil receiving spaces, a pipe leading from the upper oil receiving space of the upper receptacle at the plane of the top of the filter unit therein to and discharging in the upper oil receiving space of the lower receptacle :whereby eil flowing therefrom will Abe .discharged on'the filterI of" the lower receptacle, ^and means for drawing oil `oii from the lower oil-receiving space ofv the lower receptacle.

2. An oil puriiier, comprising a pair'of receptacles` eachV having `arbottorn and side wall,v one of said. receptacles `being disposed upon the other whereby thegbottom' w-all of the upper receptacle forms a closing top wall for `the lowerreceptacle,
