| The most important element in any drawing is the line. It's quality--thickness, drakness, straightness and evenness--are or primary importance to the draftsman, as therefore are the instruments used to draw it. |

| Cross Hatching Tool or Section Liner. 14" long. F. Weber & Co. Philadelphia. Pat'd. July 14, 1891. Metal contraption on maple base. Ingenious device for drawing closely uniformly spaced lines at and consistent intervals. The angle of the line is selected by adjusting the angular wood straight edge. The increment for the spacing is then selected by the adjustable stop at lower left. As each line is drawn, the lever at left is pushed to move the straight edge by one increment along the length of the steel rod. |
| Technical Pens by Kohinoor. These pens have acquired the generic title of Rapidograph. Set of 7 pens with ink in gray plastic case. The line quality is not necessarily improved over the steel ruling pens, but these produced consistent lines of specified width, were easier to use on short notice, and less prone to sudden catastrophic smearing. |
