ABSTRACT:
A vertical cylindrical member is supported by a frame adjacent a plurality of rotatable horizontally mounted rollers that support a plate to be marked. A carriage is mounted for vertical reciprocal movement on the cylindrical member. A piston cylinder assembly having an extensible piston rod positioned therein is secured at one end to the upper portion of the cylindrical member. The end of the piston rod is connected to the carriage. A shaft is rotatably supported by and positioned below the carriage. A marking wheel having a plurality of marking elements retained on the surface thereof is secured to the end of the shaft in overlying relation with the surface of the plate to be marked. The piston cylinder assembly maintains a preselected marking pressure on the marking wheel of the plate to be marked. A prime mover is mounted on the carriage and is drivingly connected by a single revolution clutch to the shaft to rotate the marking wheel and urge the marking elements into marking engagement with the surface of the plate to mark the plate. After each actuation of the clutch the marking wheel is returned to position the marking elements relative to the surface of the plate so that the plate may pass unobstructed beneath the marking wheel. Actuation of the clutch effects single rotation of the marking wheel and marking engagement of each of the marking elements with the surface of the plate to impress a preselected marking arrangement on the surface of the plate. A second piston cylinder assembly is connected to the carriage and the frame and is operable to laterally pivot the carriage through an angle of 90.degree. to move the marking wheel into and out of marking position relative to the plate to facilitate a change of marking elements on the marking wheel or marking wheels on the shaft.
