This invention relates to an oil filter which has been more particularly designed for use in connection with the lubricating systems of automotive vehicles, although it may be used inother installations and machinery where it is desirable to filter the lubricant.
One of its objects is the provision of a 'simple, inexpensive and durable filter of this character which will thoroughly and eRectively remove an solid particles from the oil, thereby ador in a saving in the oil con sumption of the engine and insuring a circulation of clean oil to its various parts requiring lubrication.
Another object of the invention is to vso organize and construct its parts that the filter may be readily cleaned, when desired, without disassembling or detaching'it from the vehicle.
A still further object is to treat the filterin elements in such a manner that they will re ain the suspended matter and yet permit the oil to flow through them to thev required' extent to insure its positive and thorough filtration.
1n the accompanying drawings :-Figure l is a side elevation of an oil filter embodying my invention. Figure 2 is a vertical longitudinal section thereof. Figure 3 is ahori; zontal section online 3 3, Fig. 2. Figure 4 is a horizontal section on line 4 4, Fig. 2. Figure 5 is a fragmentary vertical section of the filter casing showing the manner ofattaching the` screw plug in place.
Similar characters of reference indicate corresponding parts throughout the several,
for example, beneath the hood and adjacent .to the engine. In its preferred construction i shown in the drawings, the filter consists ofy `ac'asing or 'receptacle 10l of sheet steel or other appropriate material through which v45 ythe oil circulates whileundergoing filtra'` tion. The top of this 'casing terminates in an .outwardly-facing annular fiange 11` to which a cover 12 is detchably secured, as by bolts 13a gasket 14 beinginserted between these parts to preventleakage of oil. The bottom of the casing has a drain opening 15 normally fitted with a screw plug 16, said opening being formed in a. collar or nut 17 pressedy firmly and tightly into a polygonally-shaped recess or depression 18 which may 1927. Serial N0. 189,264@
in Fig. 5 and when the collan is pressed into position, said rim is forced downwardly and snugly against the collar-neck 20 to formv a leak-proof joint between these parts. The collar is ,likewise polygonal to conform to the shape of the recess and to prevent its turning during'the application and removal of the screw plug 16. Preferably formed'in.
the. cover 12 and opening into the filter-casing 10 is an inlet and outlet 22, 23adapted to be connected by pipes24, 25, respectively, with the lubricating system of the vehicle.
Suspended within the casing from its cover 12 is a filtering clement which com-` prises a plurality of fibrous or porous pads I or disks 26tightly compressed between said cover and a lower head plate 27 These iiter-pads have central openings 28A through which a combined tie member and filter discharge tube 29 pass, the upper end of the latter extending' through the cover and having an external thread thereon for receiving a clamping nut 3() and the head plate 27 being /secured to the lower end of said tube by a clamping bolt 31. /for the filtered oil may be formed'between the pad-openings 28 and the discharge tube. InI its side, the latter has a plurality of lat-- eral ports 33 for conducting the oil from the drainage channel 32 to the discharge passage 34 ofthe tube, the uppermost set of portsf 35 y opening into the filter-,outlet 23.
' The filter 'pads 26 are preferably made of felted fibrous material, such as wool, treated i A drainage channel 32 with a 'substance whose solution, on' evap` oration, yields a pervious residue possessing adhesive pro erties which not only acts to`sfti'cl' the -pa s together as 'a 'unit but also renders them sufiiciently time permit the passage of oil through them, thus lnsuring a positive andthorogh filtra- `tion' of tlle'oiL The, substance for so treatdense .to retain the suspended matter and at the same as forvexam'pl, sodium silicate (water glass) or a solution of cellulose acetate and a suitable organic slplvent, such as acetone, ethyl ror amyl acetate. This treatment of the pads Vmaybe accomplished in any suitable manner,
' for example, by boiling vthem for a short period in the silicate or othersolution, during which period they become thoroughly impregnated or saturated. The silicate or other solution isdistributed uniformly throughout y the fibers of the pads and when the latter are driedythe silicate or other material assumes a more or lessV pervious 1 condltion, which greatly mcreases the filtering efficiency of 'the pads Without detriment to their capacity.
By treating the pads in this fashion, a thorough removal of the solid particles from the oil is insured, such particles being deposited mainly on the outside surface of the filtering media and may be readily removed inthe y manner presently to be. described.
The filtering unit may be readily cleaned, when desired, by simply removing the drain plug 16 and then admitting air underl pressure through the filter discharge tube 29. To this end, the nut 30 at the upper end of this tube has an inlet' port 36 opening into the tube-,passage .34 and ,normally sealing this port is a screwcap 37. By attaching the hose as indicated in Fig. 2. In passing from this casing to the discharge tube 29 the oil is de- 35 livered under pressure through the filter pads 26, which effectually remove the solid particles from the used oil and deliver4 it cleany and pure to the drainage channel 32 from which it flows into the discharge pas 40 sage 34 of the tube 29 and thence outwardly through the casing-outlet 23 to the parts of thesysteln to be lubricated.
I claim as my invention 1. A filter of the character described, com- 45 prising a sheet metal casing having an inlet and an outlet, a filter discharge tube arranged in said casing and communicating with said outlet, a filtering element surrounding and discharging into ysaid tube, the'bottom of the 50 casing having` a polygonal recess therein contamlng an openmg, and a polygonal collar containing adrain opening fitted in said re- 4 cess and having a depending neck engaging the recess-opening and forming a pressed-5-5 leak-proof joint with the marginal edge thereof. y
2. A device of the character described, comprising a casing having a polygonalre'- cess therein containing an ope'mng, and a 60 polygonal collar containing a drain opening fitted in said recess and havin a neck engaging the recess 'opening an forming a pressed leak-proof joint with the marginal edge thereof.
