Etch A Sketch

Basic mechanism of operating a 2-dimensional plotter.  The numbered components correspond to those that move the stylus horizontally, and the lettered components with those that move it vertically.  The device has ten pulleys, six cables, two rails, and a stylus.  Pulley 1 (single-groove) connects to pulley 2 (triple-groove) via a short infinite reciprocating cable.  Pulley 2 connects to 3 (also triple-groove) via a longer reciprocating cable attached along its upper course to one end of the vertical rail (6), and then a third cable runs from 2 to 3, 4, and 5 (4 and 5 are single-groove) via another much longer loop of cable between 4 and 5 to the other end of the vertical rail.  Likewise, A connects to B, B connects to C and attaches to the horizontal rail (F), and finally B connects to C, D, and E, attaching to F at its other end between D and E.  Turning pulley 1 counterclockwise makes 2 rotate the same way, and this makes all pulleys connected to 2 (3, 4, and 5) do the same.  The rail these cables connect to (6, connection points marked in red) move to the left both at ends, making the stylus move in the same direction along the other rail (F).

Clockwise movement of pulley 1 has the opposite effect. Pulleys A-E operate the same as 1-5, and act on the horizontal rail (F) to slide the stylus up and down along the vertical one (6).

Etch A Sketch is a mechanical drawing toy invented by André Cassagnes of France and subsequently manufactured by the Ohio Art Company and now owned by Spin Master of Toronto, Canada.

An Etch A Sketch has a thick, flat gray screen in a red plastic frame. There are two knobs on the front of the frame in the lower corners. Twisting the knobs moves a stylus that displaces aluminum powder on the back of the screen, leaving a solid line. The knobs create lineographic images. The left control moves the stylus horizontally, and the right one moves it vertically.
