ABSTRACT:
Actuating apparatus for actuating a device such as a brake or clutch or the like comprising output force transfer apparatus movable between an open non-force applying position and closed force applying positions whereat a variable output force is applied to the device in the closed force applying positions; and wherein the actuating apparatus causes, movement of the output force transfer apparatus between the open position and the closed positions and exerts variably increasable output forces in the closed positions. A constant force applying apparatus continuously exerts a uniform substantially constant force of pre-selected magnitude on the output force transfer apparatus in the closed positions and holds the output force transfer apparatus in the open position. A cam apparatus changes the point of application of force from the constant force applying apparatus to the output force transfer apparatus and varies the amount of output force exerted by the output force transfer apparatus while external force application apparatus actuates the cam apparatus; and force limiting apparatus limits the maximum amount of the output force applicable to the device.
