INVENTORS Frank M. Zupu n Jerome N. Zurek y AH rney SIPI'ION PAINT SPRAY CUP ASSEMBLY BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates in general to spray gun paint cups and more particularly to a spray gun paint cup cover having improved fastening and venting means.
2. Description of the Prior Art Siphon paint cups for spray guns are usually attached directly to the gun by means of a coupling on one end of a conduit extending through the cup cover into the cup or can. An air hose also attached to the spray gun creates a pressure drop in the conduit for enabling delivery of the paint through the conduit to the gun nozzle. A hole located in a concave wall portion of the cup cover intermediate the rim and cover axis provides atmospheric air for maintaining the pressure drop. In the course of using the gun and attached cup, the cup is shaken or momentarily held upside down to distribute the paint particles in the solvent and is held at various angles or attitudes for better spray application, resulting in paint drip through the cover hole. Paint drip in turn may either contact the surface being painted and mar the same or form an undesirable and inconvenient deposit on the operators hands and adjacent surfaces.
In addition, the cup or can cover is usually secured to the can by means of a threaded sleeve on the conduit which engages a U-shaped bracket to snug the cover against the cup rim. In order to facilitate manual manipulation of the sleeve, a disc or flange extends therefrom; however, the torque exerted on the sleeve is limited by the tendency of the operators hand or fingers to slip along the disc surface or rim.
SUMMARY OF THE INVENTION To avoid the foregoing problems, the present invention provides a can cover having a pair of partially overlapping radial bosses on opposite sides of the cover with the boss located on the lower cover side terminating adjacent but spaced from the central axis and conduit while the boss on the upper cover side terminates adjacent the rim. A relatively large diameter longitudinal passageway is provided in the upper side boss from adjacent the rim through the cover for axial communication with a longitudinal small diameter passageway extending radially inwardly and downwardly through the lower side boss for communicating with the can interior adjacent the central conduit. Thus, air may readily enter the can, while the central conduit serves as a baffle to limit the direct access of paint into the passageway when the can is shaken. Further, the elongate upwardly directed passageways limit the direct escape of paint while serving as a reservoir to hold paint for permitting the held paint to thereafter drip back into the reservoir. The end of the large diameter opening adjacent and above the can rim also permits one of the operators fingers or digits to be facilely held over the opening when the can is shaken or held upside down to prevent paint from escaping therethrough.
Additionally, the sleeve on the central conduit is provided with a plurality of radially extending spokes which may be engaged by the operators fingers to exert a torque on the sleeve independent of frictional engagement for tightening the cover on the can.
The foregoing and other objects of the invention will become apparent on examination of the following specification and claims together with the drawings.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a top elevational view of the spray gun cup and cover assembly incorporating the principles of the present invention;
FIG. 2 is a sectional view taken along the line 2-2 in FIG. 1;
FIG. 3 is an enlarged fragmentary view illustrating the vent construction; and
FIG. 4 is an enlarged fragmentary view illustrating the apparatus for securing the cover and cup.
BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT In FIG. 1 a siphon spray gun cup assembly is indicated by the reference character 10. The assembly 10 includes a cup-shaped housing or can 12 whose open end receives a cover 14.
The cover 14 is a die cast material having thickness of approximately 0.175 inch and a peripheral edge 16 in overlapping engagement with the cup rim. A recess is formed in the cover adjacent the edge and a gasket 18 therein bears against the cup rim to seal the edge.
Extending through the cover along the central axis of the cover is a conduit 20. Conduit 20 is secured to the cover by means of a ring 22 and a threaded nipple 24 engaging the threaded lower end of the conduit 20. An extension conduit 26 having a coupling 28 is threaded on the nipple 24 and extends to a position adjacent the bottom wall 30 of the can. The upper end of the conduit 20 carries a coupling 32 for sealingly fastening the conduit 20 and can 12 to a spray gun in a conventional manner.
An axially movable sleeve 34 encircles the conduit 20 intermediate the ring 22 and the coupling 32 and the lower end of the sleeve 34 adjacent ring 22 is threaded for engagement with a threaded opening in the back wall 36 of a U-shaped locking bracket 38. integrally formed on the sleeve 34 between the upper surface of wall 36 and coupling 32 are three equi-angularly spaced radial spokes 40 to enable a turning torque to be applied to the sleeve directly transverse to a radial line from the sleeve axis. The end legs 52 of the locking bracket 38 are each provided with a recess 54 for engagement with a respective locking lug 56 fixed to and projecting in opposite directions from the side of the can 12.
Aradially extending boss 58 tapering outwardly of the cover towards the cover rim or periphery to a height of substantially 0.31 inch with the end face 60 at an angle of 45 overlaps at its inward end a second radial boss 62 tapering in a radial inward direction from the cover 14 toward the can interior and terminating substantially 1% inch from the central cover axis with the end face at an angle of substantially 22 to the axis. A
In use the can 12 is filled with liquid paint to a desired level and the cover 14 then placed over the open end with the recesses 54 in bracket 38 engaging the locking lugs 56. The radial spokes 40 are then rotated to thread the sleeve 34 through the bracket wall 36 and against the ring 22 to thereby tighten the cover 14 against the can rim. Since the pressure applied against the spokes is transverse to the axis of the spokes, frictional slippage is avoided and maximum force is applied for tightening the cover. The coupling 32 is engaged with an appropriate fitting on the spray gun and tightened to connect the conduits 20 and 26 with the spray gun to communicate paint to the gun.
On the application of air under pressure to the gun, pressure is reduced in the conduit 20 causing paint to flow from the cup through the conduit 20 to the gun under atmospheric pressure supplied through the passageways 64 and 66. When the cup 12 is shaken to aid in dispersion of the paint or held at various attitudes, the paint sloshing in the cup will primarily strike the nut 24 which acts as a baffle to prevent paint entering the passageway 66, while the angular position and length of the passageways will limit entrance and exit of the paint to and from the can. If some paint does enter and pass through passageway 66, the total length of passageways 64 and 66 will prevent direct paint escape and instead the paint may collect in the lower portion of passageway 64 during any particular shaking or tilting movement of the can and then drip back into the cup through passageway 66, while air continues to enter in the portion of the passageways above the liquid level. Holding a finger over the easily accessible face 60, when vigorously shaking or holding the can upside down, of course, prevents paint from leaking out.
The above is a description of an improved spray gun paint siphon cup assembly whose inventive concepts are believed disclosed by the foregoing description and accompanying claims.
