Claim 4
Independent Claim
123 words
The method of making a bearing cage composed of a ring of circumferentially spaced closed annular pockets, each with radially spaced open inner and outer peripheral ends connected by a continuous radial wall and connecting portions between the pockets holding the pockets in ring-defining relation which comprises: winding a first material filament a plurality of times in a manner to provide a pluality of superimposed filament portions defining each individual pocket, winding a second material filament a plurality of times to provide superimposed filament portions connecting the pockets formed by the first filament Material portion together in circumferentially spaced-apart ring formation, the second different material filament forming the connecting portions and bonding the superimposed filament portions together into fixed ring and pocket shape.
Claim 5
Dependent Claim
58 words
The method of claim 2 wherein the first material filament is wound to provide a portion of the walls of each pocket in the manner of a band whose inner surface defines the pocket, and the second filament is wound to encompass the outer surface of said bands and to connect the bands circumferentially together in spaced-apart relation.
Claim 6
Dependent Claim
35 words
The method of claim 3 wherein the second material filament is wound to also provide a portion of each pocket''s defining wall radially beyond the bands formed by the winding of the first material filament.
Claim 7
Dependent Claim
130 words
A filament wound bearing cage having a plurality of circumferentially spaced-apart roller element receiving pockets defined by wound filament portions and connecting portions circumferentially between the pockets connecting the defined pockets to one another in a ring shape, a portion of each pocket defined by a first filament wound to provide a band around the pocket, the band having open radially inner and outer ends and a continuous radial wall intermediate the ends, the radial wall defining a portion of the pocket on its inner surface, the bands being received in a ring defined by a second different material filament wound around each of the bands and between each adjacent band into a wound ring of circumferentially spaced pockets, the filaments being bonded together into fixed ring and pocket shape.
Claim 8
Dependent Claim
130 words
A filament wound bearing cage having a plurality of circumferentially spaced-apart roller element receiving pockets defined by wound filament portions and connecting portions circumferentially between the pockets connecting the defined pockets to one another in a ring shape, a portion of each pocket defined by a first filament wound to provide a band around the pocket, the band having open radially inner and outer ends and a continuous radial wall intermediate the ends, the radial wall defining a portion of the pocket on its inner surface, the bands being received in a ring defined by a second different material filament wound around each of the bands and between each adjacent band into a wound ring of circumferentially spaced pockets, the filaments being bonded together into fixed ring and pocket shape.
Claim 9
Dependent Claim
