Abstract
Abstract A plastic disc-like bearing for a turret member housing of an airless spray gun includes a roughened generally spherical outer surface that engages a generally spherical seat of the housing. An integral peripheral flange of the bearing has a roughened surface that engages a flange seat of the housing adjacent the periphery of the spherical seat. A smooth generally spherical inner surface of the bearing engages a generally spherical turret member received within the housing and a conventional plastic ring cooperates with the plastic bearing to support the turret member for rotational movement between a spraying position and a non-spraying position. In the spraying position, a spraying orifice of the turret member faces outwardly of apertures in the plastic bearing and the housing, the aperture of the bearing being the smaller of the two.

Claim 1
Independent Claim
138 words
In an airless spray gun, the combination comprising, an apertured housing having a spherical seat adjacent the aperture, a generally spherical turret member received within the housing and including a sprAying orifice for spraying a fluid outwardly of the housing through the aperture thereof, a disc-like plastic bearing located between the spherical seat and the turret member and having an aperture adjacent the aperture of the housing, the bearing including a roughened generally spherical outer surface engaging the spherical seat of the housing and a smooth generally spherical inner surface engaging the spherical turret member, turret member support means engaging and rotatably supporting the spherical turret member in cooperation with the plastic bearing, and means for rotating the turret member within the turret member support means and the plastic bearing between a spraying position and a non-spraying position.
Claim 2
Dependent Claim
138 words
In an airless spray gun, the combination comprising, an apertured housing having a spherical seat adjacent the aperture, a generally spherical turret member received within the housing and including a sprAying orifice for spraying a fluid outwardly of the housing through the aperture thereof, a disc-like plastic bearing located between the spherical seat and the turret member and having an aperture adjacent the aperture of the housing, the bearing including a roughened generally spherical outer surface engaging the spherical seat of the housing and a smooth generally spherical inner surface engaging the spherical turret member, turret member support means engaging and rotatably supporting the spherical turret member in cooperation with the plastic bearing, and means for rotating the turret member within the turret member support means and the plastic bearing between a spraying position and a non-spraying position.
Claim 3
Dependent Claim
184 words
In an airless spray gun, the combination comprising, an apertured housing including a generally spherical seat adjacent the aperture and a flange seat adjacent the periphery of the spherical seat, a generally spherical turret member received within the housing and having a spraying orifice for spraying a fluid outwardly of the housing through the aperture thereof, a disc-like plastic bearing located between the spherical seat and the spherical turret member and having an integral flange at the periphery thereof, the bearing including an aperture adjacent to and of a smaller size than the aperture of the housing, the bearing including a roughened generally spherical outer surface engaging the spherical seat of the housing and a roughened surface on the side of the flange engaging the flange seat, the bearing including a smooth generally spherical inner surface engaging the spherical turret member, turret member support means engaging and rotatably supporting the spherical turret member in cooperating with the plastic bearing, and means for rotating the turret member within the turret member support means and the plastic bearing between a spraying position and a non-spraying position.
Claim 4
Dependent Claim
