Control means for spraying apparatus

In a gas-operated spraying apparatus having a body, a nozzle mounted at a forward end of said body, a needle located coaxially of said nozzle, said needle being retractable in said nozzle to dispense media to be sprayed, medium feed means and propellant feed means, an operating member, and control means manipulated by said operating member for controlling the retraction of said needle and hence of the dispensation of the medium to be sprayed, the improvement wherein said control means comprises:- coupling means supporting said operating member, said coupling means comprising a first support member wherefrom said operating member is pivotally suspended at a first location, and a second movable, support member, said second support member serving, on movement in a first direction, to effect retraction of said needle, said operating member being pivotally suspended from said second support member at a second location spaced from said first location, whereby said operating member is in suspension between said first and second support members, said suspension permitting both arcuate movement of said operating member to move said second support member in said first direction to retract said needle, and linear movement of said operating member perpendicular to the axis of said needle, in which movement of said second support member is minimized.
