Abstract:
1. A transmission for use with an exercise machine, said exercise machine having two foot pedals and a plurality of substantially equally sized linear hydraulic dampers each of said hydraulic dampers having a piston therein and a return-spring and said transmission comprising: (a) a pinion-post, (b) a drive shaft concentrically mounted on and pivotal around said pinion-post, (c) a drive-wheel fixedly and concentrically located around said drive shaft, (d) a first means for making said dependent on each other and for transmitting mechanical energy from said foot pedals to said drive-wheel, (e) a driven-wheel fixedly and concentrically located around said drive shaft, (f) a second means for transmitting mechanical energy from said driven-wheel to said hydraulic dampers, (g) a structural means for holding said linear hydraulic dampers, said pinion-post, said drive shaft, said drive-wheel, said first means, said driven wheel, and said second means in a working positional relationship to each other whereby said first means in combination with said return-springs maintain each of said foot pedals at its neutral position.
