Abstract
Abstract A filter housing assembly for the filtering of oil in automobile engines and the like which can be connected directly to the engine block of most models of engines without special adapters or additional plumbing by virtue of the provision of a nonconcentric mounting configuration for the mounting plate. The exterior housing receives an inner liner consisting of an ordinary No. 2 1/2 tin can, which in turn contains any type of low cost filtering media, such as toilet tissue. The inner liner is supported at the bottom so that its bottom wall is spaced away from the bottom of the outer container, permitting flexing of the inner container if pressure changes occur, and the inner liner traps the sludge so that the filter can be changed without having to clean the outer container. Parallel flow is achieved in the filter media for greater efficiency.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
282 words
An oil filter housing assembly of a type capable of use with various types of filtering elements in conjunction with engines of the type having coaxially disposed engine oil conduits, the combination, comprising: a circular cover plate, said cover plate having an inlet aperture and a plurality of outlet apertures, said outlet apertures being disposed in a concentric pattern about said inlet aperture, the center axis of said inlet aperture being offset from the center point of said cover plate, means for attaching said cover plate directly to an engine block, said attaching means comprising threaded connecting means engaging an oil conduit of said engine to couple said conduit to an aperture of said cover plate, said attaching means thereby further placing the other oil conduits of said engine in fluid flow relationship with the other apertures of said cover plate; an exterior cylindrical housing with a bottom wall, means for threadably attaching said housing to said cover plate, an inner cylindrical liner with a bottom wall, said lines removably situated in close fitting relationship inside said exterior housing, a tube concentrically located within said liner and extending substantially from said cover plate to the bottom wall of said liner, said tube having a top end adjacent said cover plate and a bottom end contacting said bottom wall said tube being of substantially lesser diameter than said liner defining an annular chamber within said liner, the top end of said tube surrounding said inlet aperture in fluid sealing relation, said tube having a plurality of apertures in the side walls thereof at a spaced interval from the bottom end thereof, said apertures communicating the interior of said tube with said annular chamber.
Claim 2

Claim 3
Dependent Claim
39 words
The assembly set forth in claim 1, further including spacer means positioned between the inside of the bottom wall of said exterior housing and the bottom wall of said liner whereby said bottom walls are maintained in spaced-apart relAtionship.
Claim 4
Dependent Claim
43 words
The assembly set forth in claim 1, further including a disc member positioned within a top edge of said liner, said disc having a central aperture receiving said tube therethrough, said disc having a plurality of additional apertures spaced about said central aperture.
Claim 5
Dependent Claim
56 words
The assembly set forth in claim 1 further including a screen member of disc-like configuration positioned within an underside of said cover plate, said screen member having a dimension substantially coterminuous with the interior dimension of said cover plate, said screen member having a nonconcentric aperture therein aligned with the inlet aperture of said cover plate.
Claim 6
Dependent Claim
