Abstract: A pantograph device is disclosed which accomplishes the duplication of a three-dimensional model to a proportionately reduced degree. The device renders a clear and distinct copy, including the undercutting of certain configurations if necessary. A guide mechanism acts a a follower for sensing the configuration of the model and transmitting its movement to a cutting mechanism which reproduces the model by cutting away unnecessary portions of a blank. The size of the copy produced by the cutting mechanism (that is, the degree of reduction from the model) can be varied in the present invention. The cutting and guide mechanisms are manufactured in alignment by the structural connections of the present invention. Furthermore, the ratios of the distance separating these mechanisms and a common print are maintained equivalent so that the size of the copy bears a similar relationship to the size of the model.
