Appeal No. 97-4214
Application 08/603,348
rear wheels 14, a battery-powered motor for driving the rear
wheels (see column 1, lines 64 through 67), a switch 50 at the
upper end of the steering mechanism for controlling the motor,
a scaffold-steadying bracket 57-59 mounted on the steering
mechanism, and a scaffold-engaging bolster 20 mounted on the
platform and frame. The scaffold-engaging bolster includes
vertical and horizontal extension members 30, 32 having end
clevises 30', 32' which can be moved into engagement with
components 60, 61 of the scaffold as illustrated in Figure 1.
The scaffold-steadying bracket also includes clevises 59 for
engaging a component of the scaffold. Rosander explains that
[a]fter the device has been positioned as shown and
described, with the clevises engaging the scaffold,
the operator may mount the scaffold and move and
guide the scaffold without dismounting. The motor
control 50 is within reach of the operator and the
handle grip 49 permits easy guiding of the device
and scaffold [column 2, lines 58 through 63].
Anticipation is established only when a single prior art
reference discloses, expressly or under principles of
inherency, each and every element of a claimed invention. RCA
