Abstract
Abstract An exercising apparatus simulating weight lifting in which a pair of cables is wound on reels mounted on a base on which the person using the apparatus stands or otherwise applies his weight. The reels on which the cables are wound are controlled by a device which limits the rate of rotation essentially independently of the force applied to the ends of the cables. A bar is preferable attached to the ends of the cables and the cables preferably extended upward from the base so that a lifting force can be applied effectively by a person standing or otherwise applyling his weight to the base. An escapement device or a centrifugal responsive friction mechanism may be used to control the unwinding speed of the reel as the person using the device applies different forces to the cable in a weight lifting type of exercise.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
138 words
A body exercising apparatus simulating weight lifting, comprising a base for supporting the body thereon, a reel means connected to said base, a cable wound on said reel means and being extendable upwardly and retractable downwardly with respect to said base, a body engaging means connected to the upper end of said cable for pulling said cable upwardly and unwinding said cable from said reel, and a mechanically actuated escapement control mechanism connected to said reel means and including an escapement wheel and means for controlling the rate of rotation of said wheel, said mechanism being operated by the force exerted by the one using the apparatus for automatically limiting the rate of rotation of said reel means and the rate of unwinding of said cable when a force is applied to said cable in the unwinding direction.
Claim 2
Dependent Claim
138 words
A body exercising apparatus simulating weight lifting, comprising a base for supporting the body thereon, a reel means connected to said base, a cable wound on said reel means and being extendable upwardly and retractable downwardly with respect to said base, a body engaging means connected to the upper end of said cable for pulling said cable upwardly and unwinding said cable from said reel, and a mechanically actuated escapement control mechanism connected to said reel means and including an escapement wheel and means for controlling the rate of rotation of said wheel, said mechanism being operated by the force exerted by the one using the apparatus for automatically limiting the rate of rotation of said reel means and the rate of unwinding of said cable when a force is applied to said cable in the unwinding direction.
Claim 3
Dependent Claim
31 words
A body exercising apparatus as defined in claim 1 in which two cables are wound on said reel means and extend upwardly from said base in spaced relation to one another.
Claim 4
Dependent Claim
28 words
A body exercising apparatus as defined in claim 2 in which a snubber is interposed along each cable between the reel and the end of the respective cable.
Claim 5
Dependent Claim
29 words
A body exercising apparatus as defined in claim 1 in which said escapement mechanism is connected to said reel means and has a toothed wheel and a pallet mechanism.
Claim 6
Dependent Claim
43 words
A body exercising apparatus as defined in claim 4 in which an arm is connected to said pallets and a weight is mounted on said arm, the weight being movable along said arm to vary the rate of operation of said escapement device.
Claim 7
Dependent Claim
23 words
A body exercising apparatus as defined in claim 5 in which said reel and said wheel are mounted on the same rotatable shaft.
Claim 8
Dependent Claim
25 words
A body exercising apparatus as defined in claim 4 in which a spring means rewinds the reel when the force is relieved on said cables.
Claim 9
Dependent Claim
36 words
A body exercising apparatus as defined in claim 1 in which said control means limits the rotation of said reel to a substantially constant maximum rate independently of the degree of force applied to said cable.
Claim 10
Dependent Claim
37 words
A body exercising apparatus as defined in claim 1 in which a housing encloses said reel and control mechanism and contains an opening in the top through which said cable extends from and retracts into said housing.
Claim 11
Dependent Claim
30 words
A body exercising apparatus as defined in claim 9 in which a lock means is provided for preventing rotation of said reel to retain said cables in a predetermined position.
Claim 12
Dependent Claim
32 words
A body exercising apparatus as defined in claim 1 in which a gauge means is provided on the free end of cable to indicate the degree of force applied to the cable.
Claim 13
Dependent Claim
28 words
A body exercising apparatus as defined in claim 1 in which a snubber is interposed along the cable between the reel means and the end of the cable.
Claim 14
Dependent Claim
39 words
A body exercising apparatus as defined in claim 12 in which each snubber includes a drum around which the cable is wound, said drum rotating freely in the cable rewind direction and resists rotation in the cable unwinding direction.
