a Iocking assembly for selectively locking said first tailstock assembly to
said first bedway; and
a second Iathe bed assembly detachably secured to one of said first and
second longitudinal ends of said first Iathe bed assembly,
wherein at least one of the quill housing portion of the first tailstock
assembly and the spindle housing portion of the headstock assembly is generally

The pertinent teachings of McCormack have been set forth above.
Caddaye's invention relates to lathes. Figure 1 shows a lathe 1 which includes a
lathe headstock 8, a demountable auxiliary bed 9, a rotatable turntable 21 carrying a
lathe bed 22 on which is mounted a tail stock 23 and a tool rest 26. The turntable 21
enables the lathe bed 22 to be rotated in various positions and to be translated such as is
shown in Figures 1, 2, 3 and 4. An auxiliary bed 24 is also demountably attached to the
bed 22 as is shown in Figure 3 and may carry a tool rest 26.
Hardy's invention relates to indexing lathes for use in pattern making and similar
work requiring angular layout operations. For purposes of this rejection, Hardy's lathe
depicted in Figure 1 includes a conventional bed 10, tailstock 12 and tool rest 14.
