188, Brakes,

291, for a fluid-resistance brake having a clutch between the brake and a rotating load to connect and disconnect the brake from the load.

254, Implements or Apparatus for Applying Pushing or Pulling Force, 300, 318, 347, and 366 for apparatus for hauling or hoisting a load, including at least one cable-pulling drum which is driven around its rotational axis by a drive having a clutch

mechanism with coaxial, rotatable, relatively shiftable axially, power-transmitting components; the clutch mechanism is linked to and is operationally influenced by a frictional brake assembly which retards the rotation of the drum.
