Coffey pertains to a turntable comprising a skeletal
framework of beams 14-17 to which a plurality of generally
pie-shaped plates 19 are secured. Coffey describes the
construction of the framework and pie-shaped plates as
follows:
The rotatable turn-table is composed of a circular
channel-beam 14 at the margin of the table; radial
I-beams 15 and 16 having their outer ends rigidly
secured to the circular beam; transverse beams 17
fixedly secured to the I-beams by angle-plates 19,
and a series of metal plates 18 extending over and
removably bolted to said beams. Said plates are
arranged in annular series with their meeting edges
over the beams 15, 16. [Page 1, lines 47-57.]

circular shape.
Coffey also discloses a plurality of wheel units mounted
