Abstract

A reciprocating spray device is provided with means for reducing vibration associated with reversal of motion at the end of each path of reciprocation. The vibration reducing means includes accelerative force transfer means which are contacted by the reciprocating spray apparatus at the points of reversal of its motion for transfer of substantially all of the reciprocating spray device accelerative forces to a spray bridge which is rigidly mounted to a carriage having shock absorbing means connected thereto and movably mounted on support means so that transferred accelerative forces from the reciprocating spray apparatus cause the carriage to move substantially parallel to and in an opposite direction from the motion of the reciprocating spray apparatus, and providing for the shock absorber to contact a fixed stop mounted in fixed relation to the supporting beam.

Claims7

Dependent claims

An apparatus for reciprocating a movable device along a given axis of reciprocation, comprising:

a movable device;
means connected to said movable device for imparting accelerating and decelerating forces to said device and a reciprocating motion to said device along the given axis of reciprocation;
carriage means;
means for mounting said carriage means for movement along a path substantially parallel to the given axis of reciprocation;
means operatively connected to said carriage means and to said reciprocating motion imparting means for transferring substantially all of the accelerating and decelerating forces associated with the reciprocation of said movable device to said carriage means to oscillate said carriage means along the path substantially parallel to the given axis of reciprocation of said movable device and substantially opposite to the motion of said device;
and
shock absorbing means for countering the motion of said carriage means produced by the accelerating and decelerating forces associated with the reciprocation of said movable device.
