Abstract
Abstract A rotary member holding assembly includes an inner cylindrical member disposed in abutting relationship within an outer cylindrical member. Each cylindrical member has a plurality of aligned through holes for accommodating rotary members such as ball bearings. In order to retain the rotary members in place, the outer cylindrical member has ball-retaining flanges concentrically disposed about the spaced openings in the outer cylindrical member and the inner cylinder member has ballretaining rings concentrically disposed within the spaced openings in the inner cylindrical member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
124 words
A rotary member holding assembly comprising an inner cylindrical member having a plurality of spaced openings, an outer cylindrical member disposed in abutting relationship about said inner cylindrical member and having a plurality of spaced openings generally aligned with the spaced openings in said inner cylindrical member, a plurality of rotary members disposed in said aligned openings, said outer cylindrical member having ballretaining flanges concentrically disposed about the spaced openings therein, said ball-retaining flanges project outwardly from the outer surface of said outer cylindrical member, said rotary members being spherical with said ball-retaining flange having a partial spherical configuration conforming generally to the spherical configuration of said rotary members, and said inner cylindrical member having ball-retaining rings concentrically disposed witin said spaced openings therein.
Claim 2
Dependent Claim
124 words
A rotary member holding assembly comprising an inner cylindrical member having a plurality of spaced openings, an outer cylindrical member disposed in abutting relationship about said inner cylindrical member and having a plurality of spaced openings generally aligned with the spaced openings in said inner cylindrical member, a plurality of rotary members disposed in said aligned openings, said outer cylindrical member having ballretaining flanges concentrically disposed about the spaced openings therein, said ball-retaining flanges project outwardly from the outer surface of said outer cylindrical member, said rotary members being spherical with said ball-retaining flange having a partial spherical configuration conforming generally to the spherical configuration of said rotary members, and said inner cylindrical member having ball-retaining rings concentrically disposed witin said spaced openings therein.
Claim 3
Dependent Claim
48 words
