摘要

Device for the composition of figures by combinable lines and bottoms, characterized by comprising a support and a laminar piece, the support being formed by a rigid plate, to which the sheet of paper to receive the figure is juxtaposed, paper that is it blocks by superimposing an articulated frame with the plate, in which the opening is limited by a step, at least in one part, and the piece is resistant sheet, with a central area that has at least two series of holes of different structure, suitable to be followed with a writing instrument, this central area being surrounded by a fin of annular section suitable for its settlement in the step of the frame, and finding the edge of the laminar piece and the step of the frame provided with corresponding recesses and projections that serve as a guide for the correct and stable positioning of the laminar piece in the frame, in which situation such piece is superimposed on the leaf to paper, and so that by moving it, the strokes made with a series of holes complement those of another series, in the composition of the figure.
