Abstract
Abstract A weight assembly adapted for use with a polymeric reel comprising a hub portion having a plurality of sockets opening through one side surface of the reel to approximately match the moment of inertia of the polymeric reel with that of a similar metal reel. The weight assembly has a plurality of weights spaced around and projecting from a ring, which weights are shaped and spaced so as to enter the sockets, and means are provided for releasably attaching the weight assembly to the reel with the weights in the sockets and the ring adjacent one side surface of the reel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
A weight assembly adapted for use with a polymeric reel comprising a hub portion having opposite side surfaces, a through central opening between said side surfaces, and a plurality of sockets opening through one side surface of said reel and spaced around said through opening, said weight assembly comprising: a support plate having a central opening; a plurality of weights spaced around and projecting axially from one side of said support plate, said weights being shaped and spaced along said support plate so as to enter the sockets in a said reel hub portion when said weight assembly is brought coaxially adjacent one side surface of a said reel; and means for releasably attaching said weight assembly to a said reel with said weights in said sockets and said support plate adjacent said one side surface.
Claim 2
Dependent Claim
136 words
A weight assembly adapted for use with a polymeric reel comprising a hub portion having opposite side surfaces, a through central opening between said side surfaces, and a plurality of sockets opening through one side surface of said reel and spaced around said through opening, said weight assembly comprising: a support plate having a central opening; a plurality of weights spaced around and projecting axially from one side of said support plate, said weights being shaped and spaced along said support plate so as to enter the sockets in a said reel hub portion when said weight assembly is brought coaxially adjacent one side surface of a said reel; and means for releasably attaching said weight assembly to a said reel with said weights in said sockets and said support plate adjacent said one side surface.
Claim 3
Dependent Claim
11 words
A weight assembly according to claim 1 comprising three spaced weights.
Claim 4
Dependent Claim
60 words
A weight assembly according to claim 1 wherein said support plate in an annular ring and said means for releasably attaching comprises spring clips projecting axially of said ring from the same side of said ring that said weights project, said spring clips being spaced between said weights and being adapted to releasably engage walls defining apertures in said reel.
Claim 5
Dependent Claim
137 words
In combination, a polymeric reel comprising a hub portion having opposite side surfaces, a through central opening between said side surfaces, and a plurality of sockets opening through one side surface of said reel and spaced around said through opening; and a weight assembly comprising a support plate having a central opening larger than the through opening of said reel; a plurality of weights spaced around and projecting axially from one side of said support plate, said weights being shaped and spaced along said support plate so as to enter the sockets in said reel hub portion when said weight assembly is brought coaxially adjacent the side surface of a said reel; and means for releasably attaching said weight assembly to said reel with said weights in said sockets and said support plate adjacent said side surface.
Claim 6
Dependent Claim
137 words
In combination, a polymeric reel comprising a hub portion having opposite side surfaces, a through central opening between said side surfaces, and a plurality of sockets opening through one side surface of said reel and spaced around said through opening; and a weight assembly comprising a support plate having a central opening larger than the through opening of said reel; a plurality of weights spaced around and projecting axially from one side of said support plate, said weights being shaped and spaced along said support plate so as to enter the sockets in said reel hub portion when said weight assembly is brought coaxially adjacent the side surface of a said reel; and means for releasably attaching said weight assembly to said reel with said weights in said sockets and said support plate adjacent said side surface.
Claim 7
Dependent Claim
14 words
A combination according to claim 4 wherein said weight assembly comprises three spaced weights.
Claim 8
Dependent Claim
63 words
A combination according to claim 4 wherein said support plate is an annular ring and said means for releasably attaching comprise spring clips projecting axially of said ring from the same side of said ring that said weights project, said spring clips being spaced between said weights, and walls defining apertures in said reel adapted to be releasably engaged by said spring clips.
