Design-making instrument

Abstract

A design-making instrument consisting of a rotatable wheel to which a sheet of paper or other material is attached. The paper may be rotated manually, mechanically, or electrically. A pen or other drawing means is applied to the surface of the rotating paper and this produces colorful designs. If the pen is held stationary while the paper is rotated, a circle is produced on the paper, unless the pen happens to be right at the center of rotation, in which case a point is produced. If the pen is moved radially while the paper is rotating, a spiral is produced, the clarity of which depends on the relative speed of radial movement of the pen and the angular velocity of the rotating paper. A spiral where successive revolutions are closely spaced resembles a set of concentric circles. Using this instrument, concentric circles in different colors may be produced on a sheet of paper. Nonconcentric circles may be produced by changing the center of rotation of the paper between drawing successive sets of circles. If the surface immediately underlying the paper contains a pattern consisting of elevated and depressed regions or due to holes in the surface, an image of the pattern is transferred to the paper by this instrument. Different designs can result from clockwise and counterclockwise rotations, and from using both directions of rotation on a single sheet of paper. Designs are produced rapidly with this instrument, and the act of producing the designs is interesting; the designs appear rapidly before one's eyes. Designs may also be prepared on a transparent sheet for projection onto a wall or screen. The wheel may consist of a plate and a replaceable template attached to said plate to increase the versatility of the instrument.
