Appeal No. 2006-0366
Application 10/382,285
and 16 for adjusting the axial position of the attaching section
relative to the top end of sub-section 16. In use,
. . . the tool is first adjusted for the height of
the ceiling to which the element, such as bolt B, is to be
mounted. This is achieved by moving housing section 16
with respect to housing section 14 . . . . Threaded rod
62 is then rotated to move it into or out of the housing
section 12 as required to match the ceiling height. The
rod coupling element 22 is threadably mounted on the rod
and seated in end bore 50. The . . . bolt is threadably
attached to the rod coupling element 22.
The element 18 is secured to a driving end of a power
tool, such as a common hand-held power drill, and the bolt
B positioned as required on the ceiling. The power drill
is then activated, which will rotate the housing and the
remainder of the tool about the longitudinal axis thereof
in direction 23'. This rotation will drive the bolt into
the ceiling. After the bolt is set into the ceiling, the
power tool can be set on reverse and activated to rotate
in direction 23". This will back the tool off of the bolt
by unscrewing the coupling element 22 from the bolt. The
bolt will be engaged with the ceiling with a greater
degree of frictional fit than with the coupling element 22
so the unscrewing motion will not remove the bolt from the
ceiling but will remove the tool from the bolt [column 4,
lines 40-65]
As disclosed, O’s tool 10 does not respond to the limitations
in independent claim 1, or the corresponding limitations in
independent claim 8, requiring the first end of the elongated hollow
tub member to be (1) adapted to receive and removably secure a drill
bit with the bit projecting from the end of the tube member, and (2)
further adapted to receive and removably secure the head of an
anchor with a rod member projecting therefrom into the hollow tube
