Model or a Lifting Screw. Model of a screw sleeve between stern and stirring stage, with a part of the keel and the backstuffs. The screw light device consists of a loose frame with a screw, which can be lifted up and down in the sleeve on a rope, which runs over a disc upstairs in the screw cooker and a disc in the screw window. The screw is a mangan screw, a four-leaf propeller, composed of two double-leaf screws that can be placed in parallel position for lighting. The screw is disconnected by pulling the ship into the ship. The vertical rails against the stern and the screws that the screw frame moves are provided with teeth; This includes palls of the screw window that prevents the back sliding. The palls can be retired so that the screw frame can pock up. Beams against the stevens keep the screw window down and must be removed before lighting. Scale 1:10 (estimation).
