Application November 30, 1956, Serial No. 625,358
14 Claims. (Cl. 210-130 This invention relates to filters adapted for filtering the lubricant of internal combustion engines forcibly circulated therethrough.
p The main objects of this invention are? First, to provide a filter which provides for relatively free passage of. lubricant therethrough and at the same time is highly eflicient.
Second, to provide a'filter comprising a cartridge fiow case ,and' a renewable or replaceable cartridge which may be quickly removed and replaced as occasion may require andbya relatively unskilled person. 7
Third, to provide a filter having these advantages which under ordinaryuse conditions cannot become clogged so as'to preventfiow of lubricant. 1 I
Objects relating to details and economies of the invention will appeartrom the. description to follow. The invention is defined and'pointed out inthe claims.
.. Patented May 1958 ofiset at its inner end constituting a gasket seat for the gasket 21 which seats upon and coacts with the gasket seat 7 on the casing bottom wall.
The outer top wall 22 is provided with an annular series of openings 23 and its outer edge is connected to the upper edge of the outer wall 21 by a seam indicated at 24 and at its inner edge to the upper end of the inner wall by a seam indicated at 25.
The foraminate inner top and bottom walls 26 and 27 respectively coact with the outer and intermediate upright walls in defining a chamber for the filtering medium 23 which is desirably ofuniformity compacted cotton linters having their full natural wax content. The outer and inner top walls coact to define an inlet header 29 while the outer and inner bottom walls coact to provide a discharge header 30. The foraminate inner wall 16 and imperforate intermediate wall 17 are spaced to receive the corrugated member 31 which is desirably of f A preferred embodimentof the invention is illustrated the body. member being desirably formed as a casting and the top member as a sheet metal stamping.
iTh'e side walls of the body member are generally cylindrical. The bottom 3-is provided with aninlet passageA' andan outlet passage 5. The inlet *passage 4 opens to the inlet tube 6 which projects upwardly to deliver. at the top of the casing. :The tube-is surrounded by the upwardly lfacingngasket seat 7 spaced therefrom to providean annular discharge 8 opening to the out-v let 5.
-The body member has an outwardly projectingfiange 9 at its upper end while the top member is provided with an outwardly projecting flange 10 seated upon thefiange 9 and .securedthereto by the locking member 11, the details of which are not illustrated as they formno part in my. present invention. The top member is provided with a vdownwardly projecting skirt portion 12 telescoping within the body member and provided with an outwardly facing gasket seat 13 for the gasket '14. The filter .cartridge surrounds and is removably associated with-ftheinlet tube. V
The filter cartridge comprises perforate wall 15, theforaminate inner wall 16 which is radially spaced from the inlet tube to provide a discharge passage 17 and an intermediateimperforate wall 181whichis spacedfrom but adjacent to the'inner' wall. The walls are concentric. p l p l I I .The outer bottom wall 19 is seamed to the lower edge of the'outer wall 15 and is provided with an upward the outer cylindrical imfiberboard stock of a character permitting relatively free passage of lubricant or other liquid filtered material therethrough. The upper end of this filter element 31 is conformed at 32 to closely embrace the inner wall 16.
The corrugated filter element 31 coacts with the imperforate wall 18 and the foraminate wall 16 to provide an annular series of outer channels 33 and an annular series of inner channels 34, the outer channels opening to the inlet header as is clearly shown in Fig. 1. The outer channels serve to uniformly distribute the liquid to be filtered'around the filtering element 31. The corrugations provide a relatively large filtering area.
The inner channels distribute the liquid for further filtering through the filtering sheet 35 wrapped around the inner wall. While the filtering member 31 and the filtering sheet 35 provide efiective filtering means the material filtered is delivered the full length of the cartridge. and flows quite freely through these media.
filtering sheet 36 is provided for the inner bottomv A bottom member.
The cartridge is further provided with an annular sup-' port member 37 having an upstanding collar 38 fitting within the inner wall 16 and a downwardly projecting flange 39 which embraces the upstanding gasket seat portion of the outer bottom member. Holes 40 in the flange provide discharge for the discharge header. The
To hold the gaskets 21and 42 upon their respective.
seats and to retain the cartridge in operating relation to other parts the top member 2 is provided with a boss.
43 providing a seat for a coil spring 44 which is seated in the thrustcollar 45 seated upon the gasket 42.
'Filters embodying my invention are highly eflicient and at the same time permit what is commonly designated as free flow, that is, a substantial flow of lubricant or other filtering material is assured.
I have not illustrated or described other embodiments or adaptations of my invention as it is believed thatthis disclosure will enable those skilled in the art toembody or adapt the invention as may be desired.
