This Engine Room section of a ship's telegraph system was part of the equipment of the Ports and Harbour ship the SS Rip. The vessel serviced and maintained the lights and buoys at Port Phillip Bay and Queenscliffe. The SS Rip was possibly the former gunboat "Albert". The ship’s communication system that was used from the late 19th century to early-to-mid-20th-century is called an Engine Order Telegraph (E.O.T.) or ship’s telegraph. The system has two parts, the Bridge Section and the Engine Room Section. The Bridge Section is usually mounted on top of a pedestal, and the Engine Room Section is often attached to a vertical surface. The standard commands printed or stamped onto the dial are the directions of AHEAD and ASTERN, and the speeds of STOP, FULL, EASY, STD. BY. and FIN. ENG. The ship’s pilot on the Bridge of a vessel sends his Orders for speed and direction to the to the Engine Room with the E.O.T. He moves the lever or levers, depending on the number of engines the ship has, to change the indicator on the Bridge Section’s dial to point in the new direction and speed of travel. This change causes the Orders to be duplicated on the Engine Room Section’s dial and a bell to signal the change simultaneously. The engineer then adjusts the ship’s engines and steering equipment to follow the pilot’s Order. The manufacturer, Mulne Bros., was a copper and brass works at 166 Sussex Street Sydney, in December 1892, and previously from 1870 at 128 to 130 Sussex Street. The company made and sold a wide range of equipment including machinery and gauges for the Railways.The Engine Room section is significant for being part of the communications system on the ship SS Rip, owned by Melbourne's Ports & Harbours department and used to service and maintain the navigation signals of Port Phillip Bay and at Queenscliffe in the mid-20th century.
