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.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.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.Noneflagstaff hill, maritime museum, shipwreck coast, warrnambool, peter carmody, carmody, newfield, shipwreck, peterborough, south west victoria, rocket, rocket crew, shipwreck artefact, flagstaff hil maritime museum, steering, steering gear, screw steering gear, sailing ship -

Barbers' Equipment, hair clippers 'BURMAN", c1950
Hair clippers are specialized implements used to cut human head hair. They work on the same principle as scissors, but are distinct from scissors and razors. :Hair clippers comprise a pair of sharpened comb-like blades in close contact one above the other which slide sideways relative to each other, a mechanism which may be manual or electrical to make the blades oscillate from side to side, and a handle. The clipper is moved so that hair is positioned between the teeth of the comb, and cut with a scissor action when one blade slides sideways relative to the other. Friction between the blades needs to be as low as possible, which is attained by choice of material and finish, and frequent lubrication. Hair clippers are operated by a pair of handles that are alternately squeezed together and released. Barbers used them to cut hair close and fast. The hair was picked up in locks and the head was rapidly depilated. Mid 20thC such haircuts became popular among boys, and young men in the military and in prisons. Burman & Sons Ltd, of Ryland Road, Birmingham, West Midlands, manufactured Burman-Douglas steering gear. Their recirculating worm and ball design of steering gear was fitted to pre-war vehicles such as the Ford Eight and the Ford Prefect, the Bedford CA, plus heavy trucks and off-road vehicles - both pre and post-war. In its day, Burman-Douglas steering-gear was regarded as.... a "quality" feature of a car chassis specification, but the worm and ball design was eventually surpassed by the cheaper rack and pinion design that dominates today. The company also manufactured motorcycle gearboxes, horse clippers and barbers’ clippers. 1871 Company founded. 1897 Private company. 1930s Gearbox for Ariel Square-four motorcycle.
