Appeal No. 2003-1327
Application 09/375,713
tractor tire above the ground surface. By contrast, Amstutz
discloses a support stand for a spring compressor, wherein the
stand includes a vertical post (5) carrying the spring clamping
members and a cruciform base (119) with what appears from Figure
9 to be screw adjustable, floor-engaging feet (143) for leveling
the stand. At column 5, line 50, et seq., Amstutz discusses
having the cruciform base of the stand therein further
constructed to receive a two wheel dolly (126) so that one person
can easily move the spring compressor from one location to
another. In this regard, note Figures 12 and 13 of Amstutz.
Simply stated, there would be no reason for one of ordinary
skill in the art to consider eliminating the castors (19) on the
mobile tractor tire transport holder of Donovan and replacing
them with a plurality of floor-engaging feet like those seen at
(143) in Figure 9 of Amstutz, and to then provide a two wheeled
dolly similar to that seen in Figures 10-12 of Amstutz for
facilitating movement of the tractor tire transport holder of
Donovan in a tilted position like that depicted in Figure 13 of
Amstutz, especially remembering that the rimmed tractor tires to
be handled by Donovan’s transport holder are “exceptionally large
and heavy” (col. 1, lines 35-36), e.g., in excess of two tons.
