Model of screw-propeller lifting gear, H. Huijgens, 1853 - 1856 demonstration model Model of a screw cooker between stern and stiral, with a part of the keel. The screw light appliance consists of a loose frame with a normal two -leaf screw, which can be hoisted up and down in the tube on a rope, which runs over two slices at the top of the screw cooker and two slices in the screw window. The screw is connected to the propeller shaft in a slot; The screw can be disconnected with the slot in a vertical position. The screw window moves over vertical rails against the stern and the screw stitch that are equipped with teeth; This includes piles of the screw window that prevent the slip. The piles can be retained by pulling two ropes, so that the screw window can sink. The joke that prevents the turning of the screw when hoisting is mounted in the screw window and is operated from above by a long cap key. The model is very detailed and can be taken out so that the composition of the lining, the propeller shaft etc. can be viewed. model maker: Netherlandsafter design by: United Kingdom wood (plant material). brass (alloy). rope
