Model of screw-propeller lifting gear. During favourable weather conditions, early steamships switched back to sail. The problem of screw propellers acting as brakes when not in use was solved by raising the propeller into the ship, utilizing the kind of lifting gear represented by this model. It was presented to the Royal Netherlands Navy in 1856 by H. Huijgens, who had seen a similar piece of equipment on the British ship HMS Duke of Wellington.
