Model : 1400

pentograph is a mechanical device used to copy, scale, or trace images and drawings. It consists of a system of arms and a stylus that allows for the copying of a drawing or image at a different scale. There are several types of pentographs, but the most common are used in drawing, drafting, and art applications. Here's more information about this interesting tool:

Key Features of a Pentograph:

  1. Arm Mechanism: A typical pentograph consists of four or more interconnected arms, often arranged in a parallelogram or triangular configuration. One arm holds a stylus (for tracing), and another holds a pen, pencil, or other drawing tool.

  2. Scaling Functionality: The pentograph can scale drawings in two ways:

    • Enlarging: By adjusting the relative positions of the arms, the device can make a drawing larger than the original.
    • Reducing: Similarly, it can shrink a drawing by scaling down the size of the traced lines.
  3. Accuracy and Precision: When used properly, a pentograph allows for accurate reproduction of drawings, ensuring the proportions are maintained whether enlarging or reducing.

  4. Applications:

    • Copying Drawings: It is used in art, design, and drafting to replicate images or plans with precision.
    • Engraving: Pentographs were once used in engraving to reproduce detailed artwork on surfaces like metal or wood.
    • Map Making: In the past, pentographs were used in cartography for enlarging or reducing maps and drawings of geographical features.
