Abstract
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.
Claims23
A spray nozzle assembly for a spray gun, comprising a nozzle tip fixedly secured in a nozzle holder, said nozzle holder having a body with a keyway formed in said body, said keyway indicating a characteristic of the spray pattern produced by said nozzle tip, said nozzle tip being fixedly secured in said nozzle holder with a predetermined orientation relative to said keyway, a key that can engage said keyway to rotate said nozzle holder together with said nozzle tip, said key being disengaged from said keyway during a spraying operation.
Apparatus comprising:
- a spray nozzle having a nozzle holder and a nozzle tip fixedly secured in said nozzle holder, said nozzle tip producing a spray pattern during a spraying operation, said nozzle holder having a keyway, and a key that can be selectively engaged with said keyway to rotate said nozzle holder together with said nozzle tip, said key being disengaged from said spray nozzle during a spraying operation.
The combination of a nozzle assembly and a manual tool, comprising:
- said nozzle assembly comprising a nozzle holder and a nozzle tip, said nozzle tip being retained in said nozzle holder in a fixed relationship to said nozzle holder, said nozzle tip producing an asymmetric spray pattern relative to an axis, said nozzle holder comprising a body having a feature that is selectively engaged with and disengaged from the tool, and said tool comprising a visual indication that indicates orientation of said spray pattern, said tool being disengaged from said nozzle holder during a spraying operation.
Apparatus comprising:
- a spray nozzle having a body with a nozzle tip that produces a spray pattern, said body having a keyway, and a key that can be selectively engaged with and disengaged from said keyway, said key comprises a handle having a shape that indicates a characteristic and orientation of an asymmetrical spray pattern.
