Adjustable turret spray nozzle

Claim 2

A spray nozzle comprising a body having a passage therein communicating with a source of material to be discharged, a plate movably mounted in relation to said body and overlying the passage therein, said plate including a plurality of orifices therethrough for selective alignment with the passage, said orifices being of different sizes to vary the rate of discharge of material from the nozzle, and means in said passage for imparting a turbulent flow to the material being discharged through an orifice in the plate, said orifices being oriented in circumferentially spaced relation in a circular pattern in said plate, means mounting the plate on said body for rotational movement about an axis centrally of the body and the circular pattern of the orifices, and means interengaging said body and plate for releasably locking the plate in rotatably adjusted position in relation to the body, said means for imparting turbulent flow consists of a sleeve, spring means biasing the sleeve toward the rotatable plate, said sleeve having a closed end engaging the plate, said closed end of the sleeve having a plurality of angulated passageways therethrough for imparting turbulent flow to the material.

Claim 3

A spray nozzle comprising a body having a passage therein coMmunicating with a source of material to be discharged, a plate movably mounted in relation to said body and overlying the passage therein, said plate including a plurality of orifices therethrough for selective alignment with the passage, said orifices being of different sizes to vary the rate of discharge of material from the nozzle, and means in said passage for imparting a turbulent flow to the material being discharged through an orifice in the plate, said orifices being oriented in circumferentially spaced relation in a circular pattern in said plate, means mounting the plate on said body for rotational movement about an axis centrally of the body and the circular pattern of the orifices, and means interengaging said body and plate for releasably locking the plate in rotatably adjusted position in relation to the body, said plate including a plurality of recesses on the inner surface thereof forming an inlet for each orifice with the recesses aligned with the passage, said means interengaging the body and plate including a spring-biased ball detent mounted within said body, wherein said recesses in the inner surface of the plate are spherical in configuration for receiving the ball detent and enabling rotation of the plate by overcoming the force exerted by the spring-biased ball detent, the entire plate being forward of the body of the nozzle and the plate''s periphery being disposed outwardly of the periphery of the body for ease of grasping thereof with the periphery of the plate being roughened for preventing slippage of the hand when manually grasping the plate and rotating it about an axis identical with the center line of the body of the nozzle.

Claim 4

A spray nozzle comprising a body having a passage therein coMmunicating with a source of material to be discharged, a plate movably mounted in relation to said body and overlying the passage therein, said plate including a plurality of orifices therethrough for selective alignment with the passage, said orifices being of different sizes to vary the rate of discharge of material from the nozzle, and means in said passage for imparting a turbulent flow to the material being discharged through an orifice in the plate, said orifices being oriented in circumferentially spaced relation in a circular pattern in said plate, means mounting the plate on said body for rotational movement about an axis centrally of the body and the circular pattern of the orifices, and means interengaging said body and plate for releasably locking the plate in rotatably adjusted position in relation to the body, said plate including a plurality of recesses on the inner surface thereof forming an inlet for each orifice with the recesses aligned with the passage, said means interengaging the body and plate including a spring-biased ball detent mounted within said body, wherein said recesses in the inner surface of the plate are spherical in configuration for receiving the ball detent and enabling rotation of the plate by overcoming the force exerted by the spring-biased ball detent, the entire plate being forward of the body of the nozzle and the plate''s periphery being disposed outwardly of the periphery of the body for ease of grasping thereof with the periphery of the plate being roughened for preventing slippage of the hand when manually grasping the plate and rotating it about an axis identical with the center line of the body of the nozzle.

Claim 5

The structure as defined in claim 2, wherein said means for imparting turbulent flow consists of a sleeve, spring means biasing the sleeve toward the rotatable plate, said sleeve having a closed end frictionally engaging the plate, said closed end of the sleeve having a plurality of angulated passageways therethrough for imparting turbulent flow to the material.

Claim 6

The structure as defined in claim 3 wherein said spring-biased sleeve includes a seal on the periphery thereof in sealing engagement with the passage with the seal enabling longitudinal sliding movement of the sleeve within said passage.

Claim 7

The structure as defined in claim 4 wherein said body including peripheral groove at the end thereof adjacent the plate, and a seal disposed in said groove and sealing the periphery of the plate to the body.
