US12326319 - Chemical irritant spray assembly that attaches to a handgun

A device that attaches to a handgun that selectively dispenses material from a pressurized canister. The device defines an internal chamber of a first length that is sized to receive the pressurized canister. A nozzle is disposed at a first end. The pressurized canister is selectively biased against the spray nozzle by being displaced within the canister chamber by a cam. The cam moves from a first position outside the internal chamber to a second position at least partially inside the internal chamber. The cam is mounted on an axle. The axle has finger levers mounted to the ends of the axle. When a finger lever is depressed, the axle turns, and the cam rotates into the internal chamber. The cam contacts the pressurized canister and displaces the pressurized canister forward against the spray nozzle. This releases the contents of the pressurized canister through the spray nozzle.

The patent describes a device that attaches to a handgun, allowing for the selective dispensing of chemical irritants from a pressurized canister through a nozzle. The mechanism utilizes a cam and axle system activated by finger levers to control the release of the canister’s contents.

Claim 1

A device for selectively dispensing material, said device comprising: a cylindrical body having a first end and a second end, an end cap that connects to said first end of said cylindrical body, said end cap containing a spray nozzle, wherein said end cap and said cylindrical body define an internal chamber of a first length; an axle having opposing ends and a center; a cam affixed to said center of said axle, wherein said cam rotates with said axle when said axle rotates, wherein said cam has a first leg that extends from said axle in a first direction and a second leg that extends from said axle in a second direction, wherein said first direction is perpendicular to said second direction; wherein said first leg of said cam selectively rotates from a first position outside said internal chamber to a second position at least partially inside said internal chamber when said axle rotates; at least one finger lever coupled to said opposed ends of said axle, wherein said at least one finger lever rotates said axle and said cam when depressed, therein causing said cam to move from said first position to said second position; and a spring that presses against said second leg of said cam and biases said cam into said first position. a cylindrical body having a first end and a second end, an end cap that connects to said first end of said cylindrical body, said end cap containing a spray nozzle, wherein said end cap and said cylindrical body define an internal chamber of a first length; an axle having opposing ends and a center; a cam affixed to said center of said axle, wherein said cam rotates with said axle when said axle rotates, wherein said cam has a first leg that extends from said axle in a first direction and a second leg that extends from said axle in a second direction, wherein said first direction is perpendicular to said second direction; wherein said first leg of said cam selectively rotates from a first position outside said internal chamber to a second position at least partially inside said internal chamber when said axle rotates; at least one finger lever coupled to said opposed ends of said axle, wherein said at least one finger lever rotates said axle and said cam when depressed, therein causing said cam to move from said first position to said second position; and a spring that presses against said second leg of said cam and biases said cam into said first position.
