Lubricating bearing and bracket mounting

Claim 2

A fixed bearing for rotatably supporting a pulley and lubricated bushing or the like, comprising a bi-ended, hollow cylindrical tube slit from an outer surface to an inner surface and from one end to the other in a direction parallel to the tube axis to form generally opposed lips, at least a portion of one lip being connected to an axially extending flange means which is disposed inwardly from said lip in chordal relationship to the balance of the bearing, the free edge of said flange means extending inwardly more than the radial distance between the inner and outer surfaces of said hollow bearing to catch oil drippings and return them to the pulley bushing.

Claim 3

A bearing according to claim 1 which is formed of a single sheet metal piece.

Claim 4

A bearing according to claim 1 wherein said pulley and oiled bushing rotate over said bearing in a predetermined direction and intercept a first lip initially and a second lip subsequently during said rotation and wherein said displaced lip portion is formed on the lip subsequently intercepted.

Claim 5

A bearing according to claim 3 wherein said tube is provided with orienting means adjacent at least one end thereof for cooperatively engaging mounting means to orient said lips in a predetermined manner within an imaginary quadrant defined by vertical and horizontal planes falling on the axis of said tube, said inwardly disposed flange lying gravitationally below said other lip with said other lip and a portion of said flange lying on a plane parallel to said vertical plane and with the lowest edge of said flange being located adjacent said bushing to return all oil dripings onto said bushing.

Claim 6

An idler pulley assembly for the complimental biasing and acceptance of a belt, said assembly comprising a spring urged bearing support fork, a bearing mounted on the support fork, means for orienting said bearing relative to said support fork, and a complimentary pulley wheel journalled on the bearing, the bearing included a bi-ended, hollow cylindrical tube slit from an outer surface to an inner surface and from one end to the other in a direction parallel to the tube axis to form generally opposed circumferentially spaced lips, at least a portion of one lip being connected to axially extending flange means which is disposed inwardly from said lip in chordal relationship to the balance of the bearing, the free edge of said flange means extending inwardly more than the radial distance between the inner and outer surfaces of said hollow bearing to catch oil drippings from said pulley and return them to the pulley.

Claim 7

An idler pulley assembly for the complimental biasing and acceptance of a belt, said assembly comprising a spring urged bearing support fork, a bearing mounted on the support fork, means for orienting said bearing relative to said support fork, and a complimentary pulley wheel journalled on the bearing, the bearing included a bi-ended, hollow cylindrical tube slit from an outer surface to an inner surface and from one end to the other in a direction parallel to the tube axis to form generally opposed circumferentially spaced lips, at least a portion of one lip being connected to axially extending flange means which is disposed inwardly from said lip in chordal relationship to the balance of the bearing, the free edge of said flange means extending inwardly more than the radial distance between the inner and outer surfaces of said hollow bearing to catch oil drippings from said pulley and return them to the pulley.

Claim 8

An assembly according to claim 5 including a bushing member fixed within said pulley member and journalled upon said bearing member, said bushing being formed of lubricant-impregnated material.

Claim 9

An assembly of the type claimed in claim 5 wherein said tube and fork orienting means includes a notch and tang means arrangement between said fork and said bearing which orients said lips in a predetermined manner within an imaginary quadrant defined by vertical and horizontal planes falling on the axis of said tube, said inwardly disposed flange lying gravitationally below said other lip with said other lip and a portion of said flange lying on a plane parallel to said vertical plane and with the lowest edge of said flange being located adjacent said bushing to return all oil drippings onto said bushing.
