Abstract
Quick release nozzle apparatus includes a fixed nozzle housing and a removable nozzle assembly which may be secured to and removed from the fixed nozzle base without the use of tools and with just one hand. The nozzle assembly is locked to the fixed base through a spring bias which urges the nozzle assembly against a pair of locking tabs on the fixed nozzle base. Rotation of the nozzle assembly relative to the nozzle base aligns relieved portions with the lock tabs for removal and installation of the nozzle assembly and aligns a shoulder or face portion with the lock tabs for securing the elements together.

Quick disconnect nozzle apparatus comprising, in combination:
- base housing means connected to a flow of fluid, including bore means through which the fluid flows;
- nozzle assembly means secured to the base housing means, including,
- a first portion extending into the bore means of the base housing means,
- a spring bore communicating with the bore means of the base housing means for receiving fluid from the base housing means, and
- an exit bore communicating with the spring bore for receiving fluid from the spring bore;
- a nozzle connected to the nozzle assembly means for receiving the flow of fluid from the exit bore;
- and
- means for removably securing the nozzle assembly means to the base housing means, including,
- lock tab means including a generally rectangular locking tab on the base housing means,
- a front face portion on the first portion of the nozzle assembly means movable adjacent to the lock tab means for securing the nozzle assembly means to the base housing means, and movable away from the lock tab means to disconnect the nozzle assembly means from the base housing means, and
- a semi-circular locking slot extending axially rearwardly from the front face for receiving the lock tab means, wherein the rectangular/circular engagement prevents relative rotation of the locking tab and the locking slot in their locked configuration.
