ABSTRACT:
Apparatus for moving a reciprocating fluid emission head automatically through successive operating cycles, into and from a space within which predetermined operations are to be performed. The apparatus includes a frame mounted at one side of the operating space, a crankshaft journaled in the frame and rotary drive means for turning the crankshaft. The crankshaft drives a parallelogram-type link arrangement that includes a main link with one end supported for guided movement in the frame, a carrier arm connected to one end of the main link, a control arm parallel to the main link and connected at one end to the carrier arm and at its other end to the crankshaft, and an intermediate link parallel to the carrier arm and connected between the main link and the control arm. The inner end of the main link is guided through a controlled path of travel whereby the spray head mounted at the outer end of the carrier arm is moved between a retracted position and an extended position located within the operating space.
