Abstract

1,092,104. Draughting machines. H. RIEFLER, O. RIEFLER, P. RIEFLER, A. RIEFLER, S. DREYER and M. RHOMBERG. Nov.9, 1964 [Nov. 8, 1963], No. 45499/64. Heading G1X. A drawing apparatus is provided with an instrument e.g. a rule 1 or curve, which can be set, when positioned at any point on a drawing board (not shown), in a selected direction 11 relative to a reference direction 10, the reference direction 10 being defined using a magnetic or electric field. As described, the drawing board contains a number of ferromagnetic parallel wires disposed beneath its surface to define a reference direction. The board may be formed of two or more layers with wires running in different directions if desired. The rule 1 has pivotally attached thereto a bar magnet 5 carrying a pointer 8 moving over a scale 7 on the rule. The magnet will align itself with a desired one or other of the reference directions of the board and the rule can thus be set at a known angle to this direction. In alternative constructions, the wire directions in the board may be detected by use of electromagnets controlling a servomotor to automatically set the rule at the desired angle. The number of electromagnetic poles may be varied to give reference angular settings at say 30‹ or 45‹ intervals, and in place of the magnets, an electric field may be employed with capacitive direction sensors.
