Entry
Brass model of a four-blade propeller that can be changed into a two-blade one.
The boss has a coupling piece with a cam at the fore end, which suggests that the screw could be disengaged without retracting the propeller shaft. The fore screw is threaded to the boss with just enough play to turn ninety degrees. The after screw is fixed with a pin through the shaft. The pitch is 13.1 cm. In aligned position the blades come together and are not placed one after the other as with the Mangin screw.
Louis Nicolas Frédéric Sollier’s screw propeller, which never passed the experimental stage, is described in numerous nineteenth-century French works on screw propulsion and encyclopaedias. The object of such designs was to enable the screw to be lifted.
Scale (estimate) 1:20.
