pantograph
n 1: mechanical device used to copy a figure or plan on a
different scale

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}.]
[1913 Webster]

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.
[PJC]

{Skew pantograph}, a kind of pantograph for drawing a copy
which is inclined with respect to the original figure; --
also called {plagiograph}.
[1913 Webster] Pantographic
