No hook.(Sheave Block) Sheave Block/Pulley ...Pulleys were used to lift goods to and from boats and at other sites at the lightstation where hauling was undertaken. Historical images and text panels in the Wilsons Promontory Museum attest to the detailed logistics that needed to be exercised in lifting and transporting goods once they had arrived by boat at the Eastern Landing. Cranes and a flying fox were employed in the nineteenth century and updated versions of this equipment served well into the twentieth century. The first cranes to be employed at the site were built just after December 1857, when tenders were called to construct two cranes prior to the commencement of building the lightstation.The first boat landing at the promontory was built on the west side of the lighthouse, which the architect, Charles Maplestone sketched in June 1859, the same month that he announced the completion of the lighthouse. His drawing shows one of the cranes as a large structure built for heavy duty lifting. Soon the east landing became the preferred place for delivering stores, but as late as 1993 a crane, timber structures and disused heavy iron machinery remained at the old site.Large rusted iron pulley, large loop at one end and smaller loop at the other.

... ...two-sheave block...In general, the more sheaves in the blocks that make up a tackle, the higher its mechanical advantage. ...A two sheave wood sailing block with metal hook and becket. ...One sheave missing. Equipment Block ...A sailing block is single or multiple pulleys with one or more sheaves that are enclosed in an assembly between cheeks or chocks. In use, a block is fixed to the end of a line, to a spar, or a surface. A rope line is reeved through the sheaves, and maybe through one or more matching blocks at the far end, to make up what's known as a tackle. The purchase of a tackle refers to its mechanical advantage. In general, the more sheaves in the blocks that make up a tackle, the higher its mechanical advantage. The matter is slightly complicated by the fact that every tackle has a working end where the final run of rope leaves the last sheave. More mechanical advantage can be obtained if this end is attached to the moving load rather than the fixed end of the tackle. Various types of blocks are used in sailing. Some blocks are used to increase mechanical advantage and others are used simply to change the direction of a line. A ratchet block turns freely when a line is pulled in one direction but does not turn in the other direction, although the line may slip past the sheave. This kind of block makes a loaded line easier to hold by hand and is sometimes used on smaller boats for lines like main and jib sheets that are frequently adjusted. A single, large, sail-powered warship in the mid-19th century required more than 1,400 blocks of various kinds and sizes.A historic item from an old sailing vessel from the late 19th to early 20th century, unfortunately.

The two-sheaved block has a mechanical advantage over a single-sheave block, using less power to lift a load. ...This metal block may have been used as part of a boat or ship's rigging or winch. The becket is the loop or ring where a shackle could be attached to use as a pulley. The two-sheaved block has a mechanical advantage over a single-sheave block, using less power to lift a load. The block was made by Tangyes, established in Birmingham, UK, in 1857, and renowned for producing high-quality, reliable machines, equipment, and tools in the late 19th and early 20th centuries. Richard Tangye (1833–1906) and four of his brothers—James, Joseph, Edward, and George—were the sons of Joseph Tangye, a Quaker Cornish miner. In 1857, they founded the engineering firm Richard Tangye & Brothers in Birmingham, UK. In 1860, the firm became Tangye Brothers and moved to Cornwall Works in Birmingham. The business encouraged inventors to join the company and develop their patents there, as happened with Weston’s differential pulley block, invented by the Englishman Thomas Aldridge Weston in 1854. Tangye bought the patent in 1858, giving the firm the sole right to manufacture it. The design received a medal for “original application, practical utility and success” at the 1862 International Exhibition in London. Also in 1858, the Tangye firm was commissioned by Brunel’s shipping company to manufacture hydraulic lifting jacks, or rams, to launch the steamship SS Great Eastern. The success of this project brought favourable attention to the firm, and it became involved in other notable projects, including the erection of Cleopatra’s Needle in London in 1878 and work on the Forth Road Bridge in Scotland. The firm underwent several name changes over the years, including James Tangye and Brothers (1857), Tangye Brothers and Price (1859), Tangye Brothers (1860), Tangye Brothers & Holman (1876), Tangye Brothers (by 1878), Tangye Ltd. (1881), and then simply Tangye. Its machinery and equipment were exported worldwide. In 1884, a branch with showrooms, offices, and a warehouse was opened in Melbourne at Cornwall House, Collins Street West. The firm was well known for producing high-quality machinery for agriculture and industry. Even today, new Tangye machinery is available for a subsidiary of Allspeeds. An extensive account of the firm’s history, names, inventions, and further references is available in Grace’s Guide, which also includes references to and diagrams of the Tangye horizontal steam engine. The block is significant for its connection to the renowned and innovative Tangye machine makers, respected for their high quality and standards. The block's maker,, Tangyes, also manufactured an 1880s steam engine, sold by a Melbourne merchant, and locally significant for its use in a late-19th century cheese factory. The block also represents the many blocks used in many industries, including the marine concerns, for rigging and lifting. Flagstaff Hill has a wide variety of these simple but very important pieces of equipment.Becket block: a metal block with two sheaves, a hook, a becket attachment point, and straps.
