Entry
Demonstration model of a capstan on a wooden frame with two levels.
The capstan is for eight bars without pawls to keep it from turning back. The wooden spindle comes down into a step on the lower level; it has two wheeled arms running up against the deckhead of the lower level and preventing the spindle from moving up. The deck around the heel has been raised with an inclined plane; around the barrel a ring with wheels has been placed to reduce friction. The purpose of this arrangement was to surge the rope up the barrel; the inclined plane can be adjusted to any angle.
Pierre Forfait (1752-1807), French engineer and Minister of the Navy during the first French Republic, invented this capstan as an improvement of the capstan design by Du Sahy (NG-MC-188). The French 40-gun frigate l’Indien was equipped with such a capstan.2 Jochem Pietersz Asmus (1755-1837), who observed this capstan on his voyage through France in 1797,3 mentions this model as part of the model collection of the Amsterdam Navy dockyard in 1807.4
Scale (estimate) 1:10.
