Abstract
A pivotable stop for machine tools, in particular panel saws, having a striker bar, on which a first stop flap is mounted in a longitudinally displaceable but fixed manner, and is connected to a measurement and display unit which determines and displays the relative position of the stop flap to the striker bar, and in which a rod can telescopically be extended and retracted, which bears a second stop flap at its free end, characterized in that a coupling placed at the measurement and display unit detachably connects the rod to the measurement and display unit.
Claims6
A crosscut fence for machine tools, in particular panel saws, having a guide bar, on which a first pivotable throwover stop is mounted in a longitudinally displaceable but fixed manner, and is connected to a measurement and display unit which determines and displays the relative position of the pivotable throwover stop to the guide bar, and in which a rod can be telescopically extended and retracted, which bears a second pivotable throwover stop at its free end, characterized in that a coupling placed at the measurement and display unit detachably connects the rod to the measurement and display unit, and in that the coupling consists of a stop bolt which can move transversely to the longitudinal axis of the rod, and which can be introduced into a bore in the rod.

A guide fence for machine tools provided with a plurality of selectively useable and independently adjustable stops and with measurement and display means associated with said stops for indicating the position thereof, wherein
- (a) a single measurement and display unit is provided for selectively indicating the position of a selected one of said plurality of stops,
- (b) said measurement and display unit being normally mechanically coupled with a first one of said stops and being movable therewith for indicating the adjusted position thereof,
- (c) means for mechanically coupling a second one of said stops to said to said measurement and display unit for movement therewith,
- (d) said first and second stops, when coupled with said measurement and display unit, being positioned at known fixed distances therefrom whereby the positions of said first and second stops can be determined from the position of said measurement and display unit.
