Pantograph \Pan"to*graph\, n. [Panto- + -graph: cf. F. pantographe.] An instrument for copying plans, maps, and other drawings, on the same, or on a reduced or an enlarged, scale. [Written also pantagraph, and incorrectly pentagraph.]
2. An electrical conducting device consisting of a collapsible frame resembling a pantograph[1], connected to the top of an electrically-powered vehicle such as a trolley, and used to conduct electrical current between the vehicle and an overhead electric wire, which supplies the power to the vehicle. The variable height of the pantograph ensures that it can move to follow variations in the height of the overhead wires, and thus make constant contact with the wires.
Skew pantograph, a kind of pantograph for drawing a copy which is inclined with respect to the original figure; -- also called plagiograph.
Wiktionary
n. 1 A mechanical linkage based on parallelograms causing two objects to move in parallel; notably as a drawing aid. 2 A pattern printed on a document to reduce the ease of photocopying. 3 (context rail transport English) A similarly-formed conductive device, now usually Z-shaped, that collects electric current from overhead lines for trains and trams. vb. To engrave by means of a pantograph (parallel linkage) system.

Wikipedia
A pantograph (Greek roots 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 movements in a second pen. If a line drawing is traced by the first point, an identical, enlarged, or miniaturized copy will be drawn by a pen fixed to the other. Using the same principle, different kinds of pantographs are used for other forms of duplication in areas such as sculpture, minting, engraving and milling.
Because of the shape of the original device, a pantograph also refers to a kind of structure that can compress or extend like an accordion, forming a characteristic rhomboidal pattern. This can be found in extension arms for wall-mounted mirrors, temporary fences, scissor lifts, and other scissor mechanisms such as the pantograph used in electric locomotives and trams
A pantograph (or "pan") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead catenary wire. It is a common type of current collector. Typically, a single wire is used, with the return current running through the track. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings.

A pantograph is a commonly used overhead suspension system for lamps and audio and video monitors in television studios. It is also used on a smaller scale in many photography studios. Using either motor driven cables or a spring system, the pantograph can be balanced so that a light touch can readjust the height of the load (usually a lamp).
