Abstract
A starter gun adapted for selectively firing blank cartridges and providing effective tear gas dissemination capability. The starter gun may comprise a pistol or revolver, and includes structure in the firing chamber and barrel thereof preventing use with conventional projectile ammunition.
Claims14
A starter gun for selectively firing blank cartridges and tear gas, comprising:
- a cylinder having a rear portion defining a plurality of firing chambers each adapted to receive selectively alternatively a blank cartridge and a tear gas cartridge, and a front portion defining a transfer passage for conducting tear gas forwardly from said firing chambers;
- a barrel extending forwardly from said cylinder front portion and defining a through-bore;
- means for firing cartridges in said firing chambers seriatim aligned with said barrel;
- wall means dividing said transfer passage of the clyinder front portion into a plurality of through-passages aligned one each with said firing chambers for providing a concentrated emission of tear gas from a fired tear gas cartridge in the associated one of said firing chambers into said barrel through-bore;
- and
- blocking means in said barrel for partially transversely blocking said through-bore at a plurality of longitudinally spaced positions, said blocking means being positioned to effectively prevent any straight through-passage longitudinally through said through-bore while permitting effectively free tear gas discharge through said through-bore.

A starter gun for selectively firing blank cartridges and tear gas cartridges, comprising:
- means defining a firing chamber having a rear portion adapted to receive selectively alternatively a blank cartridge and a tear gas cartridge, and a front portion;
- means for firing a cartridge in said chamber;
- and
- a barrel extending forwardly from said front portion of the firing chamber means and defining a through-bore free of any straight through-passage extending longitudinally rectilinearly through said through-bore to prevent ejection of a projectile straight therethrough while permitting effectively free tear gas discharge therethrough.

- a cylinder having a rear portion defining a plurality of firing chambers each adapted to receive selectively alternatively a blank cartridge and a tear gas cartridge, and a front portion defining a transfer-passage for conducting tear gas forwardly from said firing chambers;
- a barrel extending forwardly from said cylinder front portion and defining a through-bore;
- means for firing cartridges in said firing chambers seriatim aligned with said barrel;
- and a plurality of flat radial dividing walls dividing said transfer-passage of the cylinder front portion into a plurality of through-passage sectors aligned one each with said firing chambers for providing a concentrated emission of tear gas from a fired tear gas cartridge in the associated one of said firing chambers into said barrel through-bore.
