Abstract:
A shield for an engraving machine or the like is disclosed that prevents the machine operator from placing his or her fingers in the work area of the machine while the ram of the machine is traveling toward the work area. The shield includes a faceplate that is attached to a slide and slide holder configuration. The slide holder is attached to the machine, while the slide is adapted to travel with the slide holder. A plunger holder is affixed to the ram, while a plunger is spring loaded to travel within the plunger holder. As the ram travels upward away from the work area, a protrusion on the plunger interacts with the slide to force the slide and faceplate in an upward direction as well, thereby clearing the work area and allowing access thereto by the machine operator. The faceplate moves upward in unison with the ram until the plunger interfaces with the slide holder, at which time the plunger disengages from the slide. The faceplate then is lowered by gravity and by a spring covering a piston back down to cover the work area in preparation for the next descent of the ram.
