  2. Pantograph - Wikipedia

    en.wikipedia.org/wiki/Pantograph

    Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...

  3. Polygraph (duplicating device) - Wikipedia

    en.wikipedia.org/wiki/Polygraph_(duplicating_device)

    A horizontal pantograph maintains identical planar (X and Y axis) movement, with two degrees of freedom; An angled pantograph descending from the bridge maintains identical vertical (Z axis) movement; A torsion beam maintains identical pen fore-and-aft tilt; A parallel linkage maintains identical pen side-to-side tilt

  4. Five-bar linkage - Wikipedia

    en.wikipedia.org/wiki/Five-bar_linkage

    This configuration is also called a pantograph, [2] [3] however, it is not to be confused with the parallelogram-copying linkage pantograph. The linkage can be a one-degree-of-freedom mechanism if two gears are attached to two links and are meshed together, forming a geared five-bar mechanism.

  5. Pantograph (disambiguation) - Wikipedia

    en.wikipedia.org/wiki/Pantograph_(disambiguation)

    A pantograph is a mechanical connected linkage of a writing instrument, like a pen, such that the movement of one pen, in tracing an image, produces identical movements in a second pen. Pantograph may also refer to: Pantograph (lighting suspension), an overhead lighting system used in television and photography

    en.wikipedia.org/wiki/Copy-evident_document

    In security printing, various methods such as void pantograph are used to create patterns that are hard to copy exactly and when copied inexactly produces an easily detectable image. This can include halftone screens that are affected by the copying process, fine line patterns in different directions that are differently affected by copying and ...

    The book is organized into three sections, on linkages, origami, and polyhedra. [1] [2]Topics in the section on linkages include the Peaucellier–Lipkin linkage for converting rotary motion into linear motion, [4] Kempe's universality theorem that any algebraic curve can be traced out by a linkage, [1] [4] the existence of linkages for angle trisection, [1] and the carpenter's rule problem on ...

    Linkage mobility Locking pliers exemplify a four-bar, one degree of freedom mechanical linkage. The adjustable base pivot makes this a two degree-of-freedom five-bar linkage. It is common practice to design the linkage system so that the movement of all of the bodies are constrained to lie on parallel planes, to form what is known as a planar ...
