ABSTRACT:
An insertable multiple stop indicator gauge for selective height, depth and workpiece platform control as between the tool and the workpiece is disclosed. The multiple stop apparatus is detachably attachable to a milling machine tool carriage and to a screw shaft operably secured to the travel of the carriage, the carriage including upper and lower casting lips, the screw shaft including an adjustable knob threaded on and about the shaft and further including a carriage stop threaded on and about the shaft, but above the adjustable knob. The present inventive improvement comprises an insertable lower stop platform for controlling depth of tool cut in the platform in which the stop platform possesses one fork-like end detachably attachable to the lower casting lip and securable thereonto by the adjustable knob, the lower support platform having a circular opening in its opposite end. There is also provided a rotatable stop collar held within the circular opening in the stop platform and a plurality of stops adjustably held within the collar, the stops parallel to the direction of carriage travel. Additionally provided is an insertable indicator platform having one fork-like end detachably attachable to the carriage stop knob, the indicator platform including receiving means at its opposite end. Additionally, the apparatus includes a plunger-type linear motion indicator fixed within the receiving means of the indicator platform, having the plunger thereof in linear alignment with a selected stop of the rotatable stop collar, such stop reflecting the desired depth of the milling tool in the workpiece, whereby travel of the indicator platform relative to the selected stop of the stop platform may be verified by viewing the face of the indicator during its downward travel with the indicator platform.
