Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
85 words
A projectile having generally cylindrical peripheral configuration and a plurality of cutting means provided along the cylindrical periphery of the projectile, said cutting means comprising: a plurality of circumferentially spaced raDially extending cutting edges intersecting the cylindrical periphery of the projectile, generally axially extending cutting edges intersecting said radially extending edges to form cutting points therebetween, the cutting points and edges being formed by generally triangularly shaped forwardly facing serrations, and there being more than four such serrations spaced about the periphery of the projectile.
Claim 2
Dependent Claim
85 words
A projectile having generally cylindrical peripheral configuration and a plurality of cutting means provided along the cylindrical periphery of the projectile, said cutting means comprising: a plurality of circumferentially spaced raDially extending cutting edges intersecting the cylindrical periphery of the projectile, generally axially extending cutting edges intersecting said radially extending edges to form cutting points therebetween, the cutting points and edges being formed by generally triangularly shaped forwardly facing serrations, and there being more than four such serrations spaced about the periphery of the projectile.
Claim 3
Dependent Claim
36 words
The invention as defined in claim 1 and having a nose portion extending forwardly of said cutting points and edges so as to engage a paper target prior to engagement with the cutting points and edges.
Claim 4
Dependent Claim
31 words
The invention as defined in claim 2 and said nose portion having a central generally flat section and a rearwardly tapered section connecting the flat section to the radially extending edges.
Claim 5
Dependent Claim
26 words
The invention as defined in claim 1 and the serrations being of uniform size and shape spaced equally circumferentially about the cylindrical periphery of said projectile.
Claim 6
Dependent Claim
114 words
A projectile having an outer side surface of generally cylindrical peripheral configuration: a nose portion on the front of the projectile; circumferentially extending forwardly facing shoulder means spaced axially rearwardly of said nose portion; a rearwardly tapered circumferentially extending intermediate surface connecting said nose portion to said shoulder means; a plurality of serrations equally circumferentially spaced about said shoulder means, there being at least one serration in each quadrant; and each serration comprising a pair of intersecting generally axially extending side surfaces forming a generally radially extending edge extending from the intersection of said shoulder means and said intermediate surface to the outer side surface and defining a cutting point at the intersection therewith.
Claim 7
Dependent Claim
114 words
A projectile having an outer side surface of generally cylindrical peripheral configuration: a nose portion on the front of the projectile; circumferentially extending forwardly facing shoulder means spaced axially rearwardly of said nose portion; a rearwardly tapered circumferentially extending intermediate surface connecting said nose portion to said shoulder means; a plurality of serrations equally circumferentially spaced about said shoulder means, there being at least one serration in each quadrant; and each serration comprising a pair of intersecting generally axially extending side surfaces forming a generally radially extending edge extending from the intersection of said shoulder means and said intermediate surface to the outer side surface and defining a cutting point at the intersection therewith.
