Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
196 words
An inertia affected hammer like cartridge disassembling device comprising: a cylindrical body portion and a handle portion extending laterally from said body portion, said body portion having a hammer head at one end, a cartridge gripping means at the other end, and a bore, the axis of which extends along the longitudinal axis and through at least a part of said body portion from said gripping means to a point between its ends where said bore opens outwardly of said body portion, said cartridge gripping means comprising an apertured plate mounted on said other end of said body portion with its aperture in line with said bore, a slidable plate slidably mounted between said other end of said body portion and said apertured plate, and trigger means for biasing said slidable plate toward the axis of said bore for gripping the casing of a cartridge inserted with its bullet end into said bore, said trigger means connected to said slidable plate for biasing said plate toward the axis of said bore and when pressure is applied to it by the hand of a user biasing said slidable plate away from the longitudinal axis of the bore.
