Abstract

10,895. Benvenuti, E. July 27. Cabin and deck lights; ports; water-escape ports. - Ships' portholes and like openings having the usual sashes or side lights are provided with sliding shutters h movable in guides g in casings j either by hand or motor power, the shutters being operable whether the sashes are in the closed or open position. The shutters are actuated by means of racks u<1> gearing with pinions u on a shaft s, which is rotated by a cylinder p through rack-andpinion gearing 3, 1, as shown in Fig. 6. A. number of shutters may be operated together through gearing, and the operation may be controlled locally, or from the engine-room or bridge. An electric motor may be used in place of the cylinder p. The rod r may also be operated by hand from the deck through bevelgearing 10, 11. Each shaft length s may be driven through a slip coupling 4, which prevents breakage in case local resistance to closing is encountered. The valves of overboard discharges may also be operated simultaneously through oonnexions with the shaft s. Should the shutters be operated by hydraulic means connected with bulkhead-door operating system, means may be provided for isolating the shutter system.
