Abstract: A range-limiter device for a weight machine. An input assembly which rotates in response to a force exerted by the user is fixed to a shaft supported on the frame of the machine. A cam is also fixed to the shaft. Two parallel arms are supported on the shaft. Mounted on substantially the entire perimeter of the cam is a cam track. A cam follower surrounds the cam track. One end of a cable is secured to the cam follower. The cable wraps around the perimeter of the cam in the cam track grooves and leaves the cam track tangentially and travels to a pulley system terminating at a weight stack of the machine. Two features of the cam follower are captured in slots on the interior surfaces of the parallel arms. To adjust the start position for the range of motion of the input assembly, the user disengages a pull pin from the hole in the cam thereby disconnecting the parallel arms from the cam. This results in disconnecting the cable from the cam.
