ABSTRACT:
A spring driven power device in which energy in a loaded spring is delivered to a rotary member. A hollow cylindrical member having a splined inside surface is provided. A stem with external splines is coaxially mounted within the hollow cylindrical member with a space between the members. A viscous material such as silicon putty is disposed in the annular space between the members. A driving spring is provided which can be a coil tension spring with connections from the spring to one of the members, preferably the hollow cylindrical member. Relative rotation between the members is resisted by the viscous material. The spring releases its energy driving the hollow cylindrical member in a manner such that the energy is released in a steady controlled manner.
