Abstract
Abstract The combination with a housing or casing having an opening for projection outwardly therethrough of a shaft, the opening being of greater diameter than the shaft and rigidly receiving a mounting projecting beyond the casing and having a bore for journalling of the shaft, an inner bearing race fixedly engaged upon the mounting exteriorly of the casing for accommodating a plurality of discrete bearings, an outer race engaged to the shaft for rotation therewith, and a pulley or wheel member fixed on the outer race radially outwardly of the fixed inner race and mounting member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
137 words
The combination with a casing having an opening in one portion thereof and a shaft of lesser diameter than said casing opening projecting outwardly therethrough, of a wheel mounting means comprising a mounting member fixed within said casing opening and projecting outwardly therebeyond, said mounting member having a bore through which said shaft extends, a fitting fixedly engaged on said mounting member in its projecting portion, a multiplicity of bearing elements arranged circumferentially about, and supported upon, said fitting, said fitting having a bearing for journalling of said shaft extending therethrough, means disposed radially outwardly of said fitting for retaining said bearing elements against displacement from operative position, a wheel having a hub portion, said hub portion being engaged upon said means retaining said bearing elements, and means interconnecting said shaft and said bearing element retaining means.
Claim 2
Dependent Claim
137 words
The combination with a casing having an opening in one portion thereof and a shaft of lesser diameter than said casing opening projecting outwardly therethrough, of a wheel mounting means comprising a mounting member fixed within said casing opening and projecting outwardly therebeyond, said mounting member having a bore through which said shaft extends, a fitting fixedly engaged on said mounting member in its projecting portion, a multiplicity of bearing elements arranged circumferentially about, and supported upon, said fitting, said fitting having a bearing for journalling of said shaft extending therethrough, means disposed radially outwardly of said fitting for retaining said bearing elements against displacement from operative position, a wheel having a hub portion, said hub portion being engaged upon said means retaining said bearing elements, and means interconnecting said shaft and said bearing element retaining means.
Claim 3
Dependent Claim
75 words
The combination as defined in claim 1 and further characterized by said mounting member being externally threaded, said fitting having an annular, internally threaded flange for engagement upon the projecting portion of said mounting member, said multiplicity of bearing elements being arranged circumferentially about the outer face of said fitting flange, said fitting having a web abutting against a confronting portion of said mounting member and said fitting bearing being provided in said fitting web.
Claim 4
Dependent Claim
44 words
The combination as defined in claim 2 and further characterized by said bearing elements being discrete roller bearings, cooperative means provided on said fitting and said means retaining said bearing elements in opposed relationship for inhibiting displacement of said roller bearings in axial directions.
Claim 5
Dependent Claim
90 words
The combination as defined in claim 3 and further characterized by said means retaining said bearing elements comprising a closure having an annular extension at its casing adjacent end for disposition radially outwardly of said bearing elements in opposed relationship to the support therefor for retaining said elements within an arrangement surrounding, but spaced from, said shaft, bearing means provided in said closure for said shaft, and means interconnecting said closure and said shaft, said wheel hub portion being engaged upon said annular extension radially outwardly of said bearing elements.
Claim 6
Dependent Claim
51 words
The combination as defined in claim 3 and further characterized by said closure having a body portion, said annular extension projecting from the casing adjacent end of said body portion, said closure having a bore for journalling of said shaft therethrough, and shaft engaging wear means provided internally of said closure.
Claim 7
Dependent Claim
137 words
The combination as defined in claim 2 and further characterized by said bearing elements being discrete roller bearings arranged in an annular pattern surroundingly of and concentric with said shaft, said means for retaining said bearing elements against displacement from operative position comprising a closure, said closure being located on the casing remote side of said fitting and having at its casing adjacent end an endwise projecting annular extension surroundingly of said bearing elements for restraining same against radially outward displacement, said means interconnecting said shaft and said bearing element retaining means being cooperative securing elements engaging said shaft to said closure, and said hub portion being engaged upon the outwardly directed face of said annular extension whereby upon rotation of said shaft rotative movement will be transmitted from said shaft to said wheel through said closure.
