Abstract
A reciprocating traversing apparatus discharges material onto, inspects marks, or cleans a device that it is traversing is provided that has reduced requirements for a driving motor, and has smoother traversing motion. A traversing mechanism has a driving motor with horsepower and torque requirements to maintain operational speed of the reversible traversing mechanism. The driving force to overcome inertia of the traversing mechanism when it reverses to traverse in the opposite direction is provided by a gas cylinder with extending arm. The traversing mechanism moving in a track has a gas cylinder at each end of the track. The extended arm of the cylinder engages the mechanism as it approaches one end of its traverse. The arm is depressed, and when the motor reverses the arm is extended by gas pressure to its original position. By the extension the arm accelerates the mechanism up to is operational speed. The motor continues to drive the mechanism to the other end of the traverse, where the mechanism engages the extended arm of the other gas cylinder.
