Abstract

883,194. Drawing instruments. HUGHES, H. R. May 19, 1960 [May 19, 1959], No. 16861/59. Class 97(3). A ruler 1 or other instrument having a guide edge to enable a pen to draw straight or curved lines has a flat surface on which the instrument is supported and an outwardly projecting raised guide edge 2 the underside 3 of which is inclined upwardly away from the guide edge 2 so that it will retain by surface tension or capillary attraction any ink which floods from the pen. The ruler 1 may be formed from a flat metal strip, stiffening ribs 6 being provided one of which may be shaped to form finger engaging ribs between the ends of the ruler 1. The guide edge 2 may be upwardly curled, as shown, or, if the ruler 1 is of plastics material, may be left plain.
