Patent ID: 8413972

Claim:
A multistation workpiece holder apparatus comprising: at least one primary base; a primary rotary table operatively connected to the at least one primary base, where the primary rotary table includes a primary center surface defining a primary through-hole located substantially at the center of the primary rotary table; a plurality of secondary bases, where each of the secondary bases is operatively connected to the primary rotary table; a plurality of secondary rotary tables, including at least a first secondary rotary table and a second secondary rotary table, where the first secondary rotary table includes a first secondary center surface defining a first secondary through-hole located substantially at the center of the first secondary rotary table at a first secondary axis, where the first secondary rotary table is operatively connected to a first secondary base, where the second secondary rotary table includes a second secondary center surface defining a second secondary through-hole located substantially at the center of the second secondary rotary table at a second secondary axis, and where the second secondary rotary table is operatively connected to a second secondary base; and a plurality of secondary rotary table motors including: a first secondary rotary table motor operatively connected to the first secondary rotary table and configured to rotate the first secondary rotary table about the first secondary axis, where the first secondary motor is disposed such that the first secondary through-hole is unobstructed by the first secondary motor, and a second secondary motor operatively connected to the second secondary rotary table and configured to rotate the second secondary rotary table about a second secondary axis, where the second secondary motor is disposed such that the second secondary through-hole is substantially unobstructed by the second secondary motor.
