Abstract. To draw thin lines in a direction leading to a point it is necessary to locate the ruling edge of a common ruler or straight- edge on the fixed point each time such a thin line is drawn, and in the case of thick lines care has to be taken to put the ruling edge away from the fixed point by a distance equal to one-half the thickness of the line to be drawn. When the fixed point is a comparatively long distance away necessitating the manipulation of a long and hence cumbersome straight-edge, the process becomes tedious and laborious and tends to lack in accuracy. The invented instrument with its telescopic and rotating action combined with its aligning device is intended to facili- tate the accurate and quick drawing of such lines.
