Abstract:

A large floor-to-ceiling easel structure includes a horizontal track on which a pair of rollers horizontally move, supporting a horizontally movable first carriage. The first carriage includes a pair of vertical guides in which a vertically movable second carriage with a movable picture support is disposed. The second carriage is connected by a pair of cables passing over respective sets of pulleys of the first carriage to a counterweight platform on which a sufficient number of counterweights are placed to counterbalance the weight of the second carriage, picture support, and a painting canvas supported thereon. An artist then can remain seated in front of a very large painting canvas, and can, with a slight force, move the painting canvas both vertically and horizontally to position any point of the canvas immediately in front of him.
