Appeal No. 96-3021
Application 08/104,452
suppressor and a shotgun barrel to which the device is threadedly
engaged. Claim 1 also recites slots (24) in the opposite end of
the breaching device which define a pair of longitudinally
extending diametrically opposed furcations (20, 22).
Independent claim 5 differs from claim 1 in that it
defines a firearm comprising a smooth bore barrel having a
threaded portion at the muzzle end thereof and a tactical
breaching device mounted on the threaded portion of the barrel.
The details of the tactical breaching device of claim 5 are
defined in the same manner as that set forth in claim 1. It is
apparent that claim 5 is broader than claim 1, in that claim 5
does not expressly limit the smooth bore barrel therein to being
that of a shotgun.
The Cox patent, applied by the examiner, is directed to
an explosively actuated, underwater riveting and punching
apparatus for driving a projectile, such as the bolt (8) seen in
Figure 1 and 2, into or through a resistant body. As generally
indicated by the examiner, this apparatus includes a smooth bore
barrel (1) and a cylindrical body or muzzle cap (e.g., 22 or 30)
