Abstract
Abstract A cartridge including a casing, said casing having a base at one end and a mouth at the other end, a propellant in said casing adjacent said base, ignition means to ignite said propellant, wad means positioned over said propellant, a projectile-surrounding member adjacent said wad means, a plurality of elongated projectiles arranged in said member and extending substantially longitudinally of said casing, filler means dispersed in and occupying the spaces between said projectiles to maintain the projectiles in a predetermined arrangement and control the dispersion of the projectiles, and a closure closing said mouth.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
95 words
A cartridge including a casing, said casing having a base at one end and a mouth at the other end, a propellant in said casing adjacent said base, ignition means to ignite said propellant, wad means positioned over said propellant, a projectile-surrounding member adjacent said wad means, a plurality of elongated projectiles arranged in said member and extending substantially longitudinally of said casing, filler means dispersed in and occupying the spaces between said projectiles to maintain the projectiles in a predetermined arrangement and control the dispersion of the projectiles and a closure closing said mouth.
Claim 2
Dependent Claim
95 words
A cartridge including a casing, said casing having a base at one end and a mouth at the other end, a propellant in said casing adjacent said base, ignition means to ignite said propellant, wad means positioned over said propellant, a projectile-surrounding member adjacent said wad means, a plurality of elongated projectiles arranged in said member and extending substantially longitudinally of said casing, filler means dispersed in and occupying the spaces between said projectiles to maintain the projectiles in a predetermined arrangement and control the dispersion of the projectiles and a closure closing said mouth.
Claim 3
Dependent Claim
14 words
The cartridge of claim 1 in which said filler means is a granular substance.
Claim 4
Dependent Claim
42 words
The cartridge of claim 1 in which said projectiles are arranged in said casing in a pattern including an outer circular row, the projectiles in said circular row being canted inwardly at an angle relative to the longitudinal axis of said cartridge.
Claim 5
Dependent Claim
51 words
The cartridge of claim 1 in which said projectiles are arranged in said casing in two concentric circular rows, an outer row including a plurality of projectiles each canted inwardly toward the central axis of said casing and an inner row including a plurality of projectiles axially aligned with the casing.
Claim 6
Dependent Claim
48 words
The cartridge of claim 1 in which said member is an open-ended cup including a sidewall and base, said cup having a plurality of slits extending longitudinally through the sidewall and into the base to divide said cup into a plurality of sections hinged centrally of the base.
Claim 7
Dependent Claim
37 words
The cartridge of claim 5 in which said projectiles each have an elongated body, a pointed nose and a plurality of fins, said fins being canted at a slight angle to increase the stability of said projectile.
Claim 8
Dependent Claim
21 words
The cartridge of claim 1 in which said wad means and said member are a single integral unit molded from plastic.
Claim 9
Dependent Claim
36 words
The cartridge of claim 1 in which said closure is an integral closure formed by infolding the sidewall adjacent the mouth of the casing and the base of the casing is formed integral with the sidewall.
Claim 10
Dependent Claim
161 words
A long-range shotshell type cartridge comprising a casing, a propellant charge in said casing, wad means positioned over said propellant including a flanged obturating wad having a skirt portIon directed toward said propellant, a cup-shaped projectile-carrying member positioned over said wad means, said cup-shaped member having a sidewall and a base, a plurality of slits extending through said sidewall and into said base to allow said member to separate into a plurality of segments as it leaves the barrel of a firearm, a plurality of elongated finned projectiles positioned in said cup in a predetermined arrangement, at least some of said projectiles being canted inwardly toward the axis of said casing, a filler dispersed in and filling the spaces between said projectiles to maintain said arrangement until the projectiles leave the gun barrel, and a layer of said filler means in a space formed between the ends of said projectiles and a closure of said casing to facilitate opening said closure.
Claim 11
Dependent Claim
161 words
A long-range shotshell type cartridge comprising a casing, a propellant charge in said casing, wad means positioned over said propellant including a flanged obturating wad having a skirt portIon directed toward said propellant, a cup-shaped projectile-carrying member positioned over said wad means, said cup-shaped member having a sidewall and a base, a plurality of slits extending through said sidewall and into said base to allow said member to separate into a plurality of segments as it leaves the barrel of a firearm, a plurality of elongated finned projectiles positioned in said cup in a predetermined arrangement, at least some of said projectiles being canted inwardly toward the axis of said casing, a filler dispersed in and filling the spaces between said projectiles to maintain said arrangement until the projectiles leave the gun barrel, and a layer of said filler means in a space formed between the ends of said projectiles and a closure of said casing to facilitate opening said closure.
Claim 12
Dependent Claim
12 words
The cartridge of claim 9 in which said filler is granulated polyethylene.
Claim 13
Dependent Claim
21 words
The cartridge of claim 9 in which said slits divide said member into four pie-shaped segments connected centrally of the base.
Claim 14
Dependent Claim
43 words
The cartridge of claim 9 in which said projectiles are arranged in two concentric rows, the projectiles in the outer row being canted inwardly toward the axis of said casing and the projectiles in the inner row being axially aligned with the casing.
