Patent ID: 7811189

Claim:
A system comprising: an actuator belt; a deflector for deflecting the actuator belt; a deflector lever coupled to the deflector; a lift lever coupled to the deflector lever, the lift lever having a fixed fulcrum between a first end and a second end of the lift lever, the second end of the lift lever being operationally connected to the deflector lever; a cam device coterminous with the first end of the lift lever, wherein the cam device comprises a cam located adjacent to the first end of the lift lever and a cam follower connected to the first end of the lift lever; a repositionable deflector rest juxtaposed, in operation, with the deflector lever at a juxtaposition point; wherein, in operation, the juxtaposition point changes during an increasing deflection period, wherein the deflector deflects an actuator belt that moves the load to a degree that is at least partially dependent upon the position of the juxtaposition point during at least a portion of the increasing deflection period; wherein the juxtaposition point changes relative to the deflector lever.
