Token system for use with dedicated rounds of ammunition
A firearm cartridge with a specially-configured token disc added to its base. The token includes an outer section and a central strike plate. The strike plate includes a strike ball at its center. The presence of the token increases the effective length of the cartridge and thereby prevents the closure of the bolt of a conventional firearm. As a result, the inventive cartridge cannot be fired in a conventional firearm.
1. A cartridge configured for use in a centerfire firearm having a defined maximum headspace, comprising:
a. a base with a centrally located primer;
b. a token disc affixed to said base of said cartridge, said token disc including,
i. an outer section,
ii. a central strike plate separated from said outer section by a cutout,
iii. an arm linking said central strike plate to said outer section,
iv. a strike ball mounted in said central strike plate, with said strike ball lying proximate said centrally located primer; and
c. wherein a thickness of said token disc is configured to produce a critical cartridge length for said cartridge that is substantially beyond said defined maximum headspace.
2. The cartridge as recited in claim 1 , wherein said outer section, said arm, and said strike plate are made as an integral piece from one material.
3. The cartridge as recited in claim 2 , wherein:
a. said strike plate is separated from said arm by a first hinge relief; and
b. said arm is separated from said outer section by a second hinge relief.
4. The cartridge as recited in claim 3 , wherein:
a. said strike plate includes a passage; and
b. said strike ball is pressed into said passage.
5. The cartridge as recited in claim 3 , wherein:
a. said strike plate includes a passage: and
b. said strike ball is pressed into said passage.
6. The cartridge as recited in claim 2 , wherein said strike ball is made of a hard metal.
7. The cartridge as recited in claim 6 , wherein said outer section, said arm, and said strike plate are made from a material selected from the group consisting of brass, aluminum, and plastic.
8. The cartridge as recited in claim 2 , wherein:
a. said strike plate includes a passage; and
b. said strike ball is pressed into said passage.
9. The cartridge as recited in claim 1 , wherein:
a. said strike plate includes a rearward surface; and
b. said rearward surface of said strike plate lies to the rear of a rearward most extent of said strike ball.
10. The cartridge as recited in claim 1 , wherein said outer section has a thickness greater than 2.0 mm.
11. The cartridge as recited in claim 1 , wherein said outer section has a thickness greater than 2.3 mm.
12. A cartridge configured for use in a centerfire firearm having a defined maximum headspace, comprising:
a. a base with a centrally located primer;
b. a token disc affixed to said base of said cartridge, said token disc including a strike ball mounted in a central strike plate, with said strike ball being centered on said centrally located primer; and
c. wherein a thickness of said token disc is configured to produce a critical cartridge length for said cartridge that is substantially beyond said defined maximum headspace.
13. The cartridge as recited in claim 12 , wherein said token disc includes:
a. an outer section;
b. a central strike plate separated from said outer section by a cutout;
c. an arm linking said central strike plate to said outer section; and
d. wherein said strike ball is mounted in said central strike plate.
14. The cartridge as recited in claim 13 , wherein:
a. said strike plate is separated from said arm by a first hinge relief; and
b. said arm is separated from said outer section by a second hinge relief.
15. The cartridge as recited in claim 13 , wherein said outer section, said arm, and said strike plate are made from a material selected from the group consisting of brass, aluminum, and plastic.
16. The cartridge as recited in claim 13 , wherein:
a. said strike plate includes a passage; and
b. said strike ball is pressed into said passage.
17. The cartridge as recited in claim 13 , wherein:
a. said strike plate includes a rearward surface; and
b. said rearward surface of said strike plate lies to the rear of a rearward most extent of said strike ball.
18. The cartridge as recited in claim 12 , wherein said strike ball is made of a hard metal.
19. The cartridge as recited in claim 12 , wherein said token disc has a thickness greater than 2.0 mm.
20. The cartridge as recited in claim 12 , wherein said token disc has a thickness greater than 2.3 mm.
