Abstract
The invention provides a guide line tracer adapted to be mounted forwardly of a line marker for marking lines on the road surface. Said guide line tracer comprises a pantograph link mechanism capable of extension and contraction through a remote control system whereby when not in use, it can be contracted to the shortest length but when in use, it can be selectively extended so as to permit the indicator to be always disposed in the most suitable position for an operator to look at. The invention further dissolves the problems of deadening the vibrations of the indicator so as to induce the indicator to trace exactly along a guide line.
Claims9
Road guide line marking apparatus including a vehicle comprising pantographic support means including a pair of ends extending longitudinally from said vehicle and formed of a plurality of pivotally articulated link members operable to enable selective longitudinal extension and contraction of said support means;
- means mounting one end of said pantographic support means to said vehicle;
- indicator means mounted proximate the other end of said pantographic support means;
- and driving means operable to effect selective longitudinal extension and contraction of said pantographic support means.
