DEFINITION

Classification: 60/413

(under subclass 325) Apparatus including structure that stores energy to be used to move the load and a manual or condition responsive means (1) controlling the input of energy to the storage means or (2) controlling the discharge of energy from the storage structure to the output motor of the apparatus.
