Christopher Scheiner, a German Jesuit, was responsible for designing and building the first pantograph in 1603. An illustration of the device can be seen in his 1630 book, Rosa ursina Sive Sol, along with other instruments he invented including a refracting telescope.

Where does the word pantograph come from?

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.

Who uses a pantograph?

Pantographs are used for reducing or enlarging engineering drawings and maps and for guiding cutting tools over complex paths. Artists specializing in miniatures use pantographs to achieve greater detail. From the 16th century onward, the speed of a ship was measured by what English invention?

What is Scheiner's invention?

Scheiner is credited with being the inventor of the pantograph, in 1630, a linkage mechanism that allows the duplication or scale-altering of a given diagram or drawing. He published his results in Pantographice, seu ars delineandi res quaslibet per parallelogrammum lineare seu cavum, mechanicum, mobile (1631).

How did the pantograph work?

The pantograph is spring-loaded and pushes a contact shoe up against the underside of the contact wire to draw the current needed to run the train. ... As the train moves, the contact shoe slides along the wire and can set up standing waves in the wires which break the contact and degrade current collection.

What is pantograph machine?

“A pantograph engraving machine, or pantograph engraver, is a pantograph which uses a cutting tool at one position on the pantograph's mechanism to engrave (cut) into a work piece a design traced out by a tracer or stylus at another position on the mechanism.

What did Christoph Scheiner do?

Christoph Scheiner was born in Wald, near Mindelheim in Swabia (southwest Germany), on 25 July 1573. ... Scheiner's talents lay in the mathematical sciences and instruments.

What is pantograph and its applications?

A pantograph is an old mechanism and is widely used in electrical locomotives to transfer electricity from catenary lines. It consist of 5 linkages forming parallelogram, each of the link is connected with the help of pin joint in order to form a revolute pair.

Why do pantographs arc?

Abstract: Pantograph arcing is a common phenomenon when the pantograph head and contact wire have sliding electrical contact. With the speed up of trains, the arcing becomes particularly serious for the irregularity of catenary and tracks, vibration between catenary and pantograph.

How does a pantograph produce an enlarged image?

It's based on parallelograms so that when moving one specified point, called the tracing stylus, along the outline of an image, an enlarged or reduced version of the image is created by the movement of another point, called the drawing stylus, which has a lead affixed to it.

How does VOID pantograph work?

Void pantographs work by exploiting the limitations and features of copying equipment. A scanner or photocopier will act as a low-pass filter on the original image, blurring edges slightly. It will also not be perfectly aligned with the directions of the document, causing aliasing.
