Abstract
Template for the drawing of circumferences, characterized in that it comprises a flat support, of reduced thickness, which has two circular openings of different diameter, in each of which a circular disc of approximately equal diameter is mounted, with the ability to turn, presenting the template in all the contour of the circular openings a step on its lower face, while the discs have, also in its outline but from its upper face another step of amplitude approximately equal to that of the openings, complementing each other steps to serve as lower stop of the discs, said discs being further provided by their upper side with pins close to their free edge, which have an external widening that exceeds the edge of the corresponding opening, to act as upper stops of the teeth. Discs against said edges, arranging, finally, the disks of a central hole and of radial rows of holes, located at predetermined distances, while the template has recorded an angular graduation near the edge of each opening.
