Jedná se o vynález Chebského rodáka Johanna Balthasara Neumana, který umožnil stavitelům práci při proporčních výpočtech sloupů - v latině se tento vynález nazývá Instrumentum Architecturea.

English translation:proportional dividers
Explanation:
proporational compass was invented by Fabrizio Mordente in 1591


Some early calculating instruments from Europe are of special interest in this
issue. One set of articles describes German calculating instruments for
determining the dimensions of elements in a neoclassical column: Nikolaus
Goldmann's "Architectural Rods" (1662) and Balthasar Neumann's proportional
dividers called "Instrumentum Architecturæ" (1713). Both instruments hark back
to the classical work on architecture by Vitruvius (40 B.C.).

sector (proportional compass)


Explanation:
The sector, also known as a proportional compass or military compass, was a major calculating instrument in use from the end of the sixteenth century until the nineteenth century. It is an instrument consisting of two rulers of equal length joined by a hinge. A number of scales are inscribed upon the instrument which facilitate various mathematical calculations.
