Abstract
Abstract A bearing assembly comprising a pair of half bearing members each of generally semi-cylindrical configuration with a pair of diametrically opposite radial surfaces, a boss protruding from one of the surfaces and a similarly shaped indentation on the opposite surface, whereby the pair of bearing members may be mated together either with the boss of one of the members in the indentation of the other member, or alternatively with the bosses abutting each other to provide two bore clearance settings for accommodation of slightly different shaft diameters or to compensate for warping, wear, or expansion rates.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
233 words
A bearing assembly comprising a pair of half bearing members each with semi-cylindrical inner bearing surfaces and outer surfaces adapted to be engaged by a support bracket, said inner and outer surface of each half bearing member terminating at a pair of diametrically opposite radial planar surfaces, each half bearing member including a boss protruding from one of said radial planar surfaces and an indentation formed in the opposite radial plane surface, bracket means for holding said half bearing members in engagement with each other with their respective radial planar surfaces oppositely disposed of each other, at least one of said half bearing members being selectively positionable in first and second end-to-end reversed positions relative to the other half bearing member and said bracket means, said boss being matingly received in said indentation when said one half bearing member is in said first position and said bosses being disposed in outer end surface abutting engagement with each other when said one half bearing member is in said second position, thereby spacing the corresponding radial planar surfaces apart with the inner bearing surfaces of said bearing members defining a generally cylindrical, but slightly ovate, bearing bore having major and minor diameters measured along diameters of said bearing assembly disposed at generally right angles relative to each other, the outer end surfaces of said bosses being generally flat and generally paralleling said radial planar surfaces.
Claim 2
Dependent Claim

A bearing assembly comprising a pair of half bearing members each with semi-cylindrical inner bearing surfaces and outer surfaces adapted to be engaged by a support bracket, said inner and outer surface of each half bearing member terminating at a pair of diametrically opposite radial planar surfaces, each half bearing member including a boss protruding from one of said radial planar surfaces and an indentation formed in the opposite radial plane surface, bracket means for holding said half bearing members in engagement with each other with their respective radial planar surfaces oppositely disposed of each other, at least one of said half bearing members being selectively positionable in first and second end-to-end reversed positions relative to the other half bearing member and said bracket means, said boss being matingly received in said indentation when said one half bearing member is in said first position and said bosses being disposed in outer end surface abutting engagement with each other when said one half bearing member is in said second position, thereby spacing the corresponding radial planar surfaces apart with the inner bearing surfaces of said bearing members defining a generally cylindrical, but slightly ovate, bearing bore having major and minor diameters measured along diameters of said bearing assembly disposed at generally right angles relative to each other, the outer end surfaces of said bosses being generally flat and generally paralleling said radial planar surfaces.
Claim 3
Dependent Claim
34 words
The structure set forth in claim 1 wherein said boss and said indentation are of approximately the same size and configuration such that said boss may be received in mating engagement by said indentation.
Claim 4
Dependent Claim
29 words
The structure set forth in claim 2 wherein said bracket means includes a bifurcated portion which partially surrounds and retentively embraces said outer surfaces of said half bearing members.
Claim 5
Dependent Claim
49 words
The combination of claim 1 wherein said boss and indentation are generally oblong circular in cross-sectional shape and the major dimensions of said indentation and boss extend along said radial planar surfaces in a path paralleling the axes of curvature of the inner surfaces of said half bearing members.
