Abstract: An energy absorber module usable with a variety of exercising machines and including an air displacement fan which is driven by a pair of pull cords through a one way clutch. The fan is contained within a housing secured to the frame of the module and the pull cords extend through guide holes in a face board also secured to that frame. The pull cords are wound upon drums which drive the fan when rotated in one direction, but which are freely rotatable in the reverse direction because of the clutch. A return cord is also wound upon each drum, but in the reverse direction to the pull cords, and is connected to a return spring for causing reverse rotation of the drums. A signal proportional to the rotational speed of the fan is processed through an electronic circuit to provide appropriate work information on a meter or recorder. The pull cords can be selectively engagable with other guide means according to the type of machine with which the module is to be used.

Abstract: A cycle exerciser having a vaned wheel rotatably mounted on a frame and arranged to absorb energy by movement of the broad surfaces of the vanes against the surrounding body of air. Rotation of the wheel is effected through a pair of foot pedals and connected chain and sprocket mechanism, and/or through a pair of handle bars. Each handle bar is pivotally connected to the frame and is also connected to a respective eccentric through a crank ring rotatably mounted on that eccentric and a drive bar connected to both the crank ring and the handle bar. The two eccentrics are arranged 180.degree. out of phase and are connected to the foot pedal assembly so as to rotate in response to both pivotal movement of the handle bars and operation of the foot pedals. As the eccentrics are drivably connected to the vaned wheel, that wheel is caused to rotate in response to rotation of the eccentrics.
