Antique Drawing Instrument Collection - Clinograph

Bookmark this page Clinograph

  • Maker: Harrison (?)
  • Date: c1900
  • Description and Notes:

    The clinograph is a simple drawing instrument which is normally working together with a T-square and functions like a section liner or an adjustable set square. To use, one of the two fixed edges is first placed against the T-square. The adjustable edge is then rotated to the desired angle of inclination, and it is held there by friction of the brass joint. To draw parallel inclined lines to represent section areas or for shading, the whole device is slide along the edge of the T-square and stopped at every equal spaced position to draw the lines. It of course can also be used for drawing parallel perpendicular lines along the other fixed edge.

    The device presented here is made of solid mahogany and brass and it is signed "The Clinograph Harrison's Patent." A very similar one is shown on page 112 of the Catalogue of the Andrew Alpern Collection of Drawing Instruments, and which is dated to late 19th or early 20th century. It is also mentioned in the book that identical ones can be found in Stanley & Co.'s 1927 catalogue and in which it is noted that there exist ones with ebony edges. Nevertheless there is no Stanley's signature on either the instrument here or the one of the Andrew Alpern Collection.
