Abstract
Abstract The disclosure embraces an exercising device such as a weight lifting device referred to as a barbell and an exercising device of a so-called dumbell type. The exercising device comprises a pair of housings mounted on a bar, each housing adapted to contain annularly-shaped weights in concentric nested relation with the innermost weights mounted on the bar and the housings secured to the bar. Each housing is provided with a cover supported on the bar and secured to the bar by releasable means. The annular nested weights in each housing are prevented against relative movements, the arrangement of weights in a housing being subject to any combination of a weight or weights with the retained weight or weights in a housing but restrained against movement in a housing and thereby render each housing and weight assembly of variable weight as desired by a user of the exerciser or weight lifting device.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
162 words
An exercising device comprising a bar, a pair of housings mounted on the bar, each of said housings having an end wall and a cylindrical peripheral wall, each housing adapted to receive a plurality of concentric annular weights, said weights being of dimensions whereby the weights are snugly nested together in each housing, the end wall of each housing having means providing a hub portion, a cover for each of the housings, each of said covers having means providing a hub portion, said innermost weight in each housing being snugly received on the bar, the outermost weight in each housing being snugly received within the cylindrical peripheral wall of a housing, the end wall of each housing having inwardly extending projections adjacent an intermediate weight in said housing, an open area in the end wall of each of said housings to facilitate removing weights from said housing, and means for securing the hub portions of the housings and covers to the bar.
