Appeal No. 2000-0784
Application No. 08/995,507
the examiner has indicated the allowability of claims 4, 5 and
16 through 21. Claims 2 and 3 have been canceled. The above
actions leave only claims 1, 6 through 15 and 22 through 24
for our consideration on appeal.
Appellants' invention is directed to a hydraulic elevator
system for moving a car (14) within a hoistway (29) and, more
particularly, to such a system that does not require a
machineroom outside the hoistway for housing the hydraulic
components (i.e., fluid tank, pump and valves associated
therewith) and electronic controller for the system. In
appellants' hydraulic elevator system the fluid tank (22) and
pump (24) are located in the hoistway (Fig. 1), while the
valve block (54), manually operable release mechanism (58) and
electronic controller (48) are located outside the hoistway in
a cabinet (50) conveniently positioned adjacent to a landing
for the elevator (Fig. 2). Independent claims 1, 11 and 22
are representative of the subject matter on appeal and a copy
of those claims may be found in the Appendix to appellants'
brief.
