US Patent 7458524 Spray nozzle with alignment key

A spray nozzle assembly includes a nozzle tip and a nozzle tip holder. The holder can be rotationally adjusted so as to change the spray pattern orientation for a nozzle tip that produces an asymmetrical spray pattern. The nozzle holder includes a keyway feature such as different sized holes that provide an indication to the operator of the nozzle pattern orientation. The holes may also be used in combination with a tool or key that allows the nozzle holder to be adjusted for a particular spray pattern orientation. The tool may optionally include a feature that indicates to an operator the spray pattern orientation. The nozzle holder may also include a recess for retaining the nozzle tip at an angle relative to an axis of the holder.
