Machine - Steering Gear, 1889

Historical information

Steering Gear Operation:
All steering was done from the stern of the ship and a steering mechanism was used to connect the rudder to the ship's wheel, often housed in a box-like construction behind the helm. The rudder was, in turn, mounted on a pintle or stern-post held in place by gudgeon's (sockets). The steering was activated with lines attached to the blocks on the two threads (half left hand, half right hand) of the steering gear.

As the helmsman turned the helm in the direction in which he wished the ship to travel, the central screw of the steering gear, which was attached to the back of the helm, turned horizontally. This caused the rods on either side of the gear to move backwards or forwards at the same time, which then turned the pintle and rudder to port or starboard.

A brief history of the Newfield (1889-1892): -

The Newfield was an iron and steel sailing barque of 1306 tons, built in 1889 by Alexander Stephen & Sons Dundee (Yard No 89) for Brownelles & Co., Liverpool.

The Newfield was on a voyage from Sharpness to Brisbane on 29 August 1892, with a cargo of 1850 tons of fine rock salt. The Cape Otway light had been sighted in squally, bumpy weather, but the captain was under the impression it was the King Island light. The ship’s chronometers were wrong, and orders were given to tack the ship away from the light, which headed it straight for the cliffs of the Victorian coast.

The vessel struck rocks about 100 yards from shore, and five feet of water immediately filled the holds. The captain gave orders to lower the boats which caused a disorganised scramble for safety among the crew. The panic resulted in the deaths of nine men, including the captain when they drowned after the boats capsized in heavy seas.

The seventeen men who regained the ship decided to wait until daylight and rowed to Peterborough in the ship’s jolly boat and gig after locals had failed to secure a rocket apparatus line to the ship. The Marine Board inquiry found the wreck was caused by a "one-man style of navigation" and that the captain had not heeded the advice of his crew.

Significance

The Newfield wreck and its collection of recovered items are heritage listed and are regarded as historically significant. They represent aspects of Victoria’s shipping history and their potential for us today to interpret the maritime history and social themes of the time. The assemblage of various Newfield artefacts held in the Flagstaff Hill Museum is not only significant for its association with the shipwreck but helps archaeologists when examining the relationship between the objects to better understand our colonial marine past.

Physical description

Ship’s steering gear, cast iron, consists of a long round metal rod into which gears have been machined. The thread of the gear from one end to almost the centre winds in a left hand direction while the thread of the gear from the other end to almost the centre winds in the right hand direction. Each end of the rod has a metal coupler attached and two narrower round rods are also attached to the coupling, one each side of the gear rod, the same length as it and parallel to it. Two more ‘S’ shaped couplers are joined to the gear rod. Each of these have an opening through which the gear rod is threaded and can move along. There is another opening in these couplers through which one of the narrower rods is threaded. The other end of this coupler has half length metal rod attached to it by a bolt through the ring at the end of the rod. One end of the steering gear still has the brass hub of the ship’s wheel solidly attached. The hub no longer has its wooden spokes but the ten holes for the spokes can be easily recognised.
