Claim:
An improved air gun for use with a source of air under pressure to alter the inflation of an article, said gun having a nozzle for passing air therethrough when said nozzle is engaged with a coupling, said nozzle having a sidewall, wherein the improvement comprises control means for selectively causing a flow of air from said air under pressure to pass from said source to said gun; said sidewall of said nozzle having an actuating port therethrough operably coupled to said control means; said control means being responsive to the blocking and unblocking of said actuating port by said coupling when said nozzle is respectively engaged and disengaged therewith; such that, when said actuating port is blocked, said control means causes said flow of air to pass from said source to said gun and such that, when said actuating port is unblocked, said control means inhibits said flow of air from passing from said source to said gun.
