Columna lignea perforata cum variis Brachiis, cochleis et aliis partibus pro variis experimentis, imprimis ad Mechanicam et Staticam pertinentibus.

Perforated wooden column with various arms, screws and other parts for various experiments, principally related to mechanics and statics.

This apparatus consists of a sectional wooden column which was used as a bracket to hold various devices employed in the experimental study of mechanics. Following the model presented by 's Gravesande in his Physices Elementa, the column comprises six parts. The lowest part has a screw thread at each end; the lower screw is to fix the column to a table by means of a nut below the table-top, while the upper screw is topped by a ring into which the middle section is fitted. The topmost section consists of a capital screwed to the top of the middle section. 's Gravesande shows several attachments for the column which make it useful as well as elegant. The bottom section has a slot, open for about two-thirds of its length, for holding accessories used in various experiments.

From Colégio dos Nobres, catalogue n.º 92.
