Abstract
Abstract Wheel balancing structure for a motor vehicle is provided wherein a ring portion of the wheel rim radially inwardly of the rim outer flange features a plurality of circumferentially spaced holes or openings therethrough. Balancing weights preferably constructed of lead are particularly shaped for tight fitting relationship with one or more of the circumferentially spaced holes. Each hole is preferably of stepped configuration throughout the length thereof to accommodate at one end a plug securely closing said one end, and at its opposite end providing an entrant opening to facilitate removal of the balancing weight. Springs and spacers are disclosed for the purposes set forth. Among the advantages flowing from practice of the present invention is a marked improvement in the aesthetic appearance of the motor vehicle, as well as specifically noted mechanical improvements.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
A rim and wheel assembly wherein said rim is provided with an outer rim flange thereon, annular means on said rim radially inwardly of the outer flange thereof provided with a plurality of circumferentially spaced holes thereon, balancing weights for tight securement in one or more predetermined holes in said annular means, and means for insertion in said one or more holes preventing movement of said balancing weight therein, each of said holes being of stepped configuration to make tight fitting contact with said balancing weights and also with said insertion means.
Claim 2
Dependent Claim
92 words
A rim and wheel assembly wherein said rim is provided with an outer rim flange thereon, annular means on said rim radially inwardly of the outer flange thereof provided with a plurality of circumferentially spaced holes thereon, balancing weights for tight securement in one or more predetermined holes in said annular means, and means for insertion in said one or more holes preventing movement of said balancing weight therein, each of said holes being of stepped configuration to make tight fitting contact with said balancing weights and also with said insertion means.
Claim 3
Dependent Claim
143 words
A rim and wheel assembly wherein said rim is provided with an outer rim flange thereon, annular means on said rim radially inwardly of the outer flange thereof provided with a plurality of circumferentially spaced holes therein, balancing weights for tight securement in one or more predetermined holes in said annular means, and means for insertion in said one or more holes preventing movement of said balancing weight therein, each of said holes having a relatively large diameter mouth portion, a relatively small diameter end portion, and an intermediate diameter portion, connecting with said mouth and end portions, in which each of said balancing weight sin sized for firm location within said intermediate diameter portion, said insertion means being adapted to effect firm closure of said mouth portion, thereby restraining each of said balancing weights against movement relative to said intermediate diameter portion.
Claim 4
Dependent Claim
143 words
A rim and wheel assembly wherein said rim is provided with an outer rim flange thereon, annular means on said rim radially inwardly of the outer flange thereof provided with a plurality of circumferentially spaced holes therein, balancing weights for tight securement in one or more predetermined holes in said annular means, and means for insertion in said one or more holes preventing movement of said balancing weight therein, each of said holes having a relatively large diameter mouth portion, a relatively small diameter end portion, and an intermediate diameter portion, connecting with said mouth and end portions, in which each of said balancing weight sin sized for firm location within said intermediate diameter portion, said insertion means being adapted to effect firm closure of said mouth portion, thereby restraining each of said balancing weights against movement relative to said intermediate diameter portion.
Claim 5
Dependent Claim
137 words
A rim and wheel assembly wherein said rim is provided with an outer rim flange thereon, annular means on said rim radially inwardly of the outer flange thereof, provided with a plurality of circumferentially spaced holes therein, balancing weights for tight securement in one or more predetermined holes in said annular means, and means for insertion in said one or more holes preventing movement of said balancing weight therein, each of said balancing weights being shaped to include a generally cylindrical body portion and connecting neck portion, the body portion of each of said balancing weights having a diameter no less than the diameter of each of said holes, each of said balancing weights and each of said insertion means being so dimensioned as to length whereby in combination they substantially entirely occupy each of said holes.
Claim 6
Dependent Claim
137 words
A rim and wheel assembly wherein said rim is provided with an outer rim flange thereon, annular means on said rim radially inwardly of the outer flange thereof, provided with a plurality of circumferentially spaced holes therein, balancing weights for tight securement in one or more predetermined holes in said annular means, and means for insertion in said one or more holes preventing movement of said balancing weight therein, each of said balancing weights being shaped to include a generally cylindrical body portion and connecting neck portion, the body portion of each of said balancing weights having a diameter no less than the diameter of each of said holes, each of said balancing weights and each of said insertion means being so dimensioned as to length whereby in combination they substantially entirely occupy each of said holes.
