Device for marking out workpieces

Claim 1

Device for marking out workpieces, said device comprising a sliding block provided with a vertical wall adapted to rest against the outer side of the workpiece, a graduated horizontal bar-shaped guider being secured with one end to the sliding block and extending laterally therefrom, the device further comprising a holder for a pin-shaped marking out member which is displaceable longitudinally of the bar-shaped guider from a starting position near said sliding block, corresponding to the zeroposition of the graduation, said holder being provided with a vertical through bore for receiving said pin-shaped marking out member, said graduated horizontal bar-shaped guider being secured at the upper side of said sliding block and said veritcal through bore for said pin-shaped marking out member being positioned in said holder so that in said starting position of said holder the axis of said bore is in the plane of the inner surface of the vertical wall of said sliding block, a second graduated horizontal bar-shaped guider, said holder of said pin-shaped member being mounted to said second graduated huorizontal bar-shaped guider and displaceable in the longitudinal direction thereof, said second bar-shaped guider being applied perpendicular to the first guider and extending at both sides thereof, said second guider being displaceable in the longitudinal direction of the first guider from a starting position, in which position the axis of the vertical bore of said holder is lying in the plane of the inner surface of the vertical side wall of said sliding block, the graduation of said second bar-shaped guider comprising a zero-position between the ends of this guider in such a way that, when said holder is in this position, the axis of the vertical bore thereof is lying in the cross section plan through the center of said sliding block.
