Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 185 words
A protective case for arrowheads, each arrowhead having a central shank, a plurality of radially-extending blades and a tip, comprising, in combination: a base adapted to receive said arrowheads, said base having a bottom wall, a side wall, defining a rim, an internal wall dividing said base into arrowhead compartments, and two pairs of opposed rib members within each of said compartments, each rib being disposed at approximately 90° to adjacent ribs and terminating in an inner edge to grippingly engage said shank of said arrowhead between said blades, whereby said arrowhead is retained within said compartment, isolated from other arrowheads in the case thereby avoiding dulling of said tip and said blades; and a cover adapted to receive and enclose said base and the arrowheads therein, said cover including an offset peripheral portion defining an interior ledge, said rim of said base abutting said interior ledge when the case is closed to resist a compressing force applied to said case, and a transverse rib which is aligned and abuts said internal dividing wall, thereby further increasing the resistance of the case to compression forces.
Claim 2
Dependent Claim 185 words
A protective case for arrowheads, each arrowhead having a central shank, a plurality of radially-extending blades and a tip, comprising, in combination: a base adapted to receive said arrowheads, said base having a bottom wall, a side wall, defining a rim, an internal wall dividing said base into arrowhead compartments, and two pairs of opposed rib members within each of said compartments, each rib being disposed at approximately 90° to adjacent ribs and terminating in an inner edge to grippingly engage said shank of said arrowhead between said blades, whereby said arrowhead is retained within said compartment, isolated from other arrowheads in the case thereby avoiding dulling of said tip and said blades; and a cover adapted to receive and enclose said base and the arrowheads therein, said cover including an offset peripheral portion defining an interior ledge, said rim of said base abutting said interior ledge when the case is closed to resist a compressing force applied to said case, and a transverse rib which is aligned and abuts said internal dividing wall, thereby further increasing the resistance of the case to compression forces.
Claim 3
Dependent Claim 22 words
The case of claim 1 wherein each rib member is attached to a side wall defining said compartment and extends inwardly therefrom.
Claim 4
Dependent Claim 20 words
The case of claim 2 wherein said rib members are substantially perpendicular to said side wall and said dividing wall.
Claim 5
Dependent Claim 76 words
A wrench for use with an arrowhead having a central shank and a plurality radially-extending blades comprising, in combination: a cylindrical housing of substantially square cross section having two pairs of opposing rib members attached to the walls of said housing and terminating in an inner edge to grippingly engage said shank of said arrowhead between said blades, whereby a torsional force manually applied to said housing is transferred to said arrowhead retained within said housing.
Claim 6
Dependent Claim 76 words
A wrench for use with an arrowhead having a central shank and a plurality radially-extending blades comprising, in combination: a cylindrical housing of substantially square cross section having two pairs of opposing rib members attached to the walls of said housing and terminating in an inner edge to grippingly engage said shank of said arrowhead between said blades, whereby a torsional force manually applied to said housing is transferred to said arrowhead retained within said housing.
Claim 7
Dependent Claim 26 words
The wrench of claim 4 wherein said rib members are substantially perpendicular to the walls of said housing and are disposed at 90° to each other.
Claim 8
Dependent Claim 31 words
A wrench as claimed in claim 4 wherein said housing defines an open end and a closed end and said rib members extend from said open end to said closed end.
