n. Same as stereogram.n. A machine for making the embossed or raised points used in New York point-printing for the blind upon sheet-metal plates, the plates being designed for use in an embossing-press for transferring the points (characters, letters, etc.) to paper. It is an adaptation of the kaleidograph and differs from it in employing a fly-wheel, operated by a foot-pedal or other power, to operate the embossing mechanism, the selection of the points and their position being controlled by the operator by means of the keyboard. See kleidograph and point-printing.n. In craniometry, an instrument for drawing orthogonal projections of skulls.
