Application No. 09/922,938
Claim 21 reads as follows:
A Iathe assembly as in claim 16, in combination with a tool rest assembly
selectively slidably engaged with one of said first and second Iathe bed
assemblies, said tool rest assembly comprising a tool support housing extending
vertically from a tool rest main body, said tool rest main body comprising a tool
rest housing and a locking assembly for selectively locking said tool rest housing
to the Iathe bed assembly, said locking assembly including a locking plate for
engaging an undersurface of a bedway of the Iathe bed assembly; a slider block
seated and disposed within said tool rest housing, a non-circular locking shaft
extending longitudinally of said housing and disposed through a bore in said slider
block, and a locking piston vertically slidably disposed in said slider block, said
locking piston having a bore for being aligned with said bore of said slider block to
receiving said Locking shaft and having a shaft for being detachably mounted to
said locking plate, whereby rotation of said locking shaft about the longitudinal axis
thereof lifts said locking piston and the locking plate mounted thereto while
pressing said block so as to clamp said housing to a bedway between the slider
block and the locking plate.
The pertinent teachings of Hardy, McCormack and Clay have been set forth
above.
The subject matter of claim 21 would not have been obvious to a person having
ordinary skill in the art at the time the invention was made for the reasons set forth above
regarding claim 16.2 Accordingly, the decision of the examiner to reject claim 21 under
35 U.S.C. § 103 is reversed.
2For reasons unknown, the examiner did not apply the patent to Caddaye
(applied in the rejection of parent claim 16) in the rejection of dependent claim 21. The
additional patent to Clay, applied in this rejection, discloses nothing therein which
makes up for the deficiency of the applied prior art discussed above with respect to
parent claim 16.
