ADJUSTABLE ADAPTER FOR GRAVITY-FEED PAINT SPRAYER

摘要

An adjustable adapter includes two arms, each having an axis, a surface substantially normal to the axis, wherein the surfaces of the arms face each other, an end and a passageway for fluid communication between the end and the opening, wherein one of the arm ends is for connection to an inlet of an applicator and the other arm end is for connection to an outlet of a container, and a fastener for pivotally couplin g the arms. One of the arm surfaces is provided with a groove in fluid communication with bo th arm openings. The groove is sealed to prevent fluid from leaking from between th e surfaces. When the fastener is in a rotation-resisting mode, the fastener forces the surfaces of the arm toward one another sufficiently to increase friction and resist rotation therebetween, and when the fastener is in a rotation-permitting mode, the fastener release s the surfaces sufficiently to decrease friction and permit rotation therebetween.
