DEFINITION

Classification: 72/445

With stored energy means to retract tool:

(under subclass 429) Apparatus provided with means (additional to the tool-driver) for developing and accumulating latent power, which power moves the tool away from the work or away from a cooperating tool.

(1) Note. In the disclosures of this subclass the energy is usually stored by or during movement of the tool toward the work, but the subclass is also intended as a locus of disclosures wherein energy is stored (e.g., a spring is cocked) by an operative or a motor.
