1. A reciprocating shaft device having an upper end and a lower end, said reciprocating shaft device comprising:
- a shaft assembly;
an inner housing;
a coil assembly including an electromagnetic coil, the electromagnetic coil being encased within the inner housing;
a nose assembly secured to the coil assembly and having a passageway extending longitudinally and generally concentrically through it, the shaft assembly extending into the passageway of the nose assembly and being generally symmetrically located and slideably mounted within the magnetic coil;
a coil cover affixed to the nose assembly and encasing the inner housing;
a cap assembly secured to the coil cover assembly at the upper end;
dampening means located at the end of the shaft assembly;
an electrical circuit means repeatedly to energize the electromagnetic coil at a variable selectable rate so as to cause the shaft assembly to reciprocate.

Abstract
A reciprocating shaft device suitable for numerous uses, including as a tattoo device, with a balanced generally symmetrical configuration having an electromagnetic coil with a shaft slidably mounted concentrically within the coil. A cylindrical housing encloses the shaft and electromagnetic coil. Damping means within the cylindrical housing quiet any noise generated by vibration. The electromagnetic coil is driven from a power source through a timer circuit and a switching circuit, the switching circuit energizing the coil with the timer circuit controlling the rate or frequency of the switching cycle.
