Abstract
Abstract The apparatus includes adjustable weights which may be raised by rotational movement of a wheel about a vertical axis. Handles are mounted on a common, rigid horizontal cross bar to cradle the user's shoulders, arms and hands therein. By remaining upright and positioning his body within the handles, the user can exercise against the weight resistance by twisting motions of his torso. The handles are gripped and rotated simultaneously by a user's hands. This rotation, in either a clockwise or counter-clockwise direction, will cause the wheel, which is rotatable about a vertical axis, to raise and lower weights.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
113 words
Exercise apparatus comprising: a vertically oriented framework; wheel means carried by said framework and rotatable about a vertical axis; adjustable resistance means connected to said wheel means and adapted to resist rotation thereof; and a pair of horizontally spaced handle means connected to said wheel means for simultaneous rotation in the same direction, each said handle means including a handle, said handles being spaced apart sufficiently to accommodate a user therebetween and permit the user to grip both handles simultaneously with his hands and, by rotating the handles and his torso about the wheel's vertical axis, rotate said wheel means in either a clockwise or counterclockwise direction and work against said resistance means.
Claim 2
Dependent Claim
113 words
Exercise apparatus comprising: a vertically oriented framework; wheel means carried by said framework and rotatable about a vertical axis; adjustable resistance means connected to said wheel means and adapted to resist rotation thereof; and a pair of horizontally spaced handle means connected to said wheel means for simultaneous rotation in the same direction, each said handle means including a handle, said handles being spaced apart sufficiently to accommodate a user therebetween and permit the user to grip both handles simultaneously with his hands and, by rotating the handles and his torso about the wheel's vertical axis, rotate said wheel means in either a clockwise or counterclockwise direction and work against said resistance means.
Claim 3
Dependent Claim
25 words
Apparatus according to claim 1 and comprising further a horizontal cross bar connected to said wheel means, said handles being mounted on said cross bar.
Claim 4
Dependent Claim
27 words
Apparatus according to claim 2 in which each of said handles comprises a hook-like member adapted to cradle therein portions of a user's shoulders, arms and hands.
Claim 5
Dependent Claim
47 words
Apparatus according to claim 3 in which said vertical axis comprises a rotatable shaft depending from the top of said framework, and means releasable mounting said cross bar on said shaft, whereby a user can position himself beneath said cross bar and shaft to operate the apparatus.
Claim 6
Dependent Claim
26 words
Apparatus according to claim 4 and comprising further cooperating adjustment means on said shaft and cross bar for adjusting the vertical position of said cross bar.
Claim 7
Dependent Claim
36 words
Apparatus according to claim 5 in which said handles are dependingly mounted from said cross bar, and comprising further cooperating adjustment means on said cross bar and handles for adjusting the horizontal spacing between said handles.
Claim 8
Dependent Claim
60 words
Apparatus according to claim 4 and comprising further a vertical post and means for releasably connecting the post to said shaft and the base of the framework so that the shaft and post comprise said vertical aixs, said cross bar being mounted medially on said post so that a user can bear against the post during operation of the apparatus.
Claim 9
Dependent Claim
26 words
Apparatus according to claim 7 and comprising further cooperating adjustment means on said post and cross bar for adjusting the vertical position of said cross bar.
Claim 10
Dependent Claim
25 words
Apparatus according to claim 8 and comprising further cooperating adjustment means on said cross bar and handles for adjusting the horizontal spacing between said handles.
Claim 11
Dependent Claim
26 words
Apparatus according to claim 1 in which said resistance means comprises variable weights carried by cable and pulley means mounted on said framework for vertical movement.
Claim 12
Dependent Claim
36 words
Apparatus according to claim 10 in which said wheel means comprises a flange and a reduced diameter drum, so that rotation of the wheel means causes a cable to be taken up by said drum .
Claim 13
Dependent Claim
35 words
Apparatus according to claim 11 in which there are two sets of said variable weights, cable and pulley means, said cable and pulley means including cables connected to said flange at diametrically opposed points thereof.
