Abstract
Abstract A vertically elongated framework encloses a stacked array of metal plates selectively attachable in any desired quantity to the lower end of a wire cable passing around an arrangement of pulleys which afford an oppositely moving, adjacent pair of vertical cable runs. A carriage, including a horizontal bar, is vertically movable on the framework and includes a pair of cable clamping mechanisms enabling the user of the machine to connect the carriage to a predetermined one of the two oppositely moving vertical cable runs, thereby providing weight resistance to the horizontal bar either in an upward or a downward direction. By clamping both cable runs concurrently the horizontal bar is immobilized at any desired elevation and can be used as a chinning bar, ballet bar or support for auxiliary equipment.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
160 words
An exercise machine comprising: a. a vertically elongated frame extending between an upper end and a lower end and including a front side, a rear side and a pair of lateral sides; b. a first means translatably mounted on said front side of said frame for vertical movement between an upper position and a lower position, said first means comprising a carriage; c. a second means attachable to said carriage for urging said carriage in a vertical upward direction; d. an exercise bar mounted on said carriage, said bar being capable of being gripped and urged by muscular effort in a vertical direction; and, e. a third means for releasably connecting said second means to said carriage, said second means comprising a fourth means for varying the force to be overcome by a user when the carriage is attached to the second means and said carriage is moved vertically up or down by a user acting on the exercise bar.
Claim 2
Dependent Claim
160 words
An exercise machine comprising: a. a vertically elongated frame extending between an upper end and a lower end and including a front side, a rear side and a pair of lateral sides; b. a first means translatably mounted on said front side of said frame for vertical movement between an upper position and a lower position, said first means comprising a carriage; c. a second means attachable to said carriage for urging said carriage in a vertical upward direction; d. an exercise bar mounted on said carriage, said bar being capable of being gripped and urged by muscular effort in a vertical direction; and, e. a third means for releasably connecting said second means to said carriage, said second means comprising a fourth means for varying the force to be overcome by a user when the carriage is attached to the second means and said carriage is moved vertically up or down by a user acting on the exercise bar.
Claim 3
Dependent Claim
105 words
An exercise machine as in claim 1 wherein said weight means includes a plurality of pulleys rotatably mounted on said frame adjacent said upper end and said lower end; a weight member comprising a plurality of vertically stacked plates located adjacent said lower end of said frame; a cable connected at one end to said weight member, the intermediate portion of said cable being carried on said pulleys for movement of said cable in dependence upon the movement of said weight member; and cable tensioning means carried on said frame and connected to the other end of said cable for maintaining tautness in said cable.
Claim 4
Dependent Claim
28 words
An exercise machine as in claim 2 wherein said weight member includes means for selectively adding or removing plates to attain the desired mass of said weight member.
Claim 5
Dependent Claim
79 words
An exercise machine as in claim 3 wherein said third means comprises two pairs of clamping blocks mounted on said carriage and straddling said cable in said intermediate portion thereof, said pair of blocks being relatively movable toward and away from each other between a first cable releasing position and a second cable clamping position; and sixth means on said carriage for urging said cable clamping blocks between said first cable releasing position and said second cable clamping posItion.
Claim 6
Dependent Claim
145 words
An exercise machine as in claim 4 wherein said plurality of pulleys includes a first pulley rotatably mounted on said upper end of said frame above said stacked plates, a second pulley rotatably mounted on said upper end of said frame above said carriage, a third pulley rotatably mounted on said lower end of said frame below said carriage, a fourth pulley rotatably mounted on said upper end of said frame above said carriage and horizontally spaced from said second pulley, and a fifth pulley rotatably mounted on said upper end of said frame and adjacent the rear side of said frame, said cable extending upwardly from said weight member and passing over said first and second pulleys, thence downwardly adjacent said carriage and around said third pulley, thence upwardly adjacent said carriage and passing over said fourth and fifth pulleys to said fifth means.
Claim 7
Dependent Claim
47 words
An exercise machine as in claim 5 wherein said fifth means includes a vertically movable weight positioned below said fifth pulley for tensioning said cable; and seventh means on said frame in the path of said weight for limiting the extent of upward movement of said weight.
Claim 8
Dependent Claim
88 words
An exercise machine as in claim 5 wherein said clamping means comprises one pair of of said pairs of clamping blocks straddling the portion of said cable extending between said second pulley and said third pulley, and another of said pair of said pairs of clamping blocks straddling the portion of said cable extending between said third pulley and said fourth pulley; said camming means comprising a pair of cams, and each of said pairs of clamping blocks is engaged by one cam of said pair of cams.
Claim 9
Dependent Claim
24 words
An exercise machine as in claim 7 further including means carried on same frame and connected to said carriage for counterbalancing the weight thereof.
Claim 10
Dependent Claim
162 words
An exercise machine as in claim 2 including a pair of spaced vertical rods projecting upwardly from said lower end of said frame and extending through corresponding apertures in each of said vertically stacked plates to effect vertical alignment thereof, each of said plates including a plurality of legs of substantially uniform height to separate each of said plates by a substantially uniform gap; a vertical tongue extending from the lower end of said frame below said plates upwardly through corresponding slots in said plates, said vertical tongue havng formed therein a plurality of horizontal openings in registry with said gaps between said plates; and, a blade capable of being inserted horizontally into a selected one of said gaps between said plates and through a corresponding one of said openings, the upper end of said tongue being attached to said one end of said cable, said cable being capable of lifting said tongue and all of the plates superposed above said blade.
Claim 11
Dependent Claim
24 words
An exercise machine as in claim 9 including means on said lower end of said frame below said plates for cushioning a load thereon.
