The design of the corkscrew may have been derived from the gun worm, which was a device from at least the early 1630s, used by men to remove unspent charges from a musket's barrel in a similar fashion. The corkscrew is possibly an English invention, due to the tradition of beer and cider, and the 'Treatise on Cider' by John Worlidge in 1676 describes "binning of tightly corked cider bottles on their sides", although the earliest reference to a corkscrew is, "steel worm used for the drawing of Corks out of Bottles" from 1681. In 1795, the first corkscrew patent was granted to the Reverend Samuel Henshall, in England. The clergyman affixed a simple disc, now known as the Henshall Button, between the worm and the shank. The disc prevents the worm from going too deep into the cork, forces the cork to turn with the turning of the crosspiece, and thus breaks the adhesion between the cork and the neck of the bottle. The disc is designed and manufactured slightly concave on the underside, which compresses the top of the cork and helps keep it from breaking apart. The winged corkscrew, sometimes called a cork extractor, butterfly corkscrew, owl corkscrew, Indian corkscrew, or angel corkscrew, has two levers, one on either side of the worm. As the worm is twisted into the cork, the levers are raised. Pushing down the levers draws the cork from the bottle in one smooth motion. The most common design has a rack and pinion connecting the levers to the body. The head of the central shaft is frequently modified to form a bottle opener, or foil cutter, increasing the utility of the device. Corkscrews of this design are particularly popular in household use. In 1880, William Burton Baker was issued British Patent No. 2950 for his double lever corkscrew, with both levers sliding onto the upper end of the shank. The first American patent was in 1930 granted to the Italian Domenico Rosati who emigrated to Chicago, Illinois, to work as bartender before prohibition. Rosati's design had an exposed rack and pinion mechanism. Such design was adapted by other brands as the wine-market grew in popularity. The winged owl version, with two side-plates covering the rack and pinion mechanism, was first designed and manufactured in 1932 by the Spanish industrial designer David Olañeta for his brand BOJ and was later adopted by others, such as the 1936 US Patent No. 98,968 by Richard Smythe marked HOOTCH-OWL https://en.wikipedia.org/wiki/CorkscrewThis object is significant as an example of an item in common use in the 19th and early 20th centuries, and that was developed further in the 1930s.Winged corkscrew with a T-shaped wooden handle, metal spring and worm-wheel screw section.None.flagstaff hill, flagstaff hill maritime museum and village, warrnambool, maritime museum, maritime village, great ocean road, shipwreck coast, corkscrew, beverages, kitchen equipment, bottle opener

Item used to repair books after their dust jackets, covers, flyleaves or pages had been damaged. These damaged items on a book were replaced and glued. The press allowed the glue to set under pressure until the repair was complete a press is also used for the gilding of books. The first book press has been documented in India around 100 BCE with various types and designs being used though the ages and are still in use today by craftsman to repair antique books.Over the centuries many materials from ivory to glass, have been used to bind books. Gilding has also long been a popular decorative treatment for book bindings and a book press is used in this operation. Since the 1800s, rare book conservationists have worked to perfect the methods used by their predecessors, and modern book binders are true craftsman with this press as an example of the equipment used in their trade. This item is significant as it is an early example of items used in book gilding and binding.Book binding press metal with square pressing surface driven by worm wheel thread and turning handle in working order.

This wooden ship's wheel originally had eight spokes but four are no longer in their sockets. One of the spokes has been shaped. Both sides of the wheel have a brass cap over the centre of the hub, covering the wooden hub. The wood is split and cracked, and parts of it have small holes, a sign of being affected by the sea worm. Thick encrustations are on parts of the wheel, showing that it has been on the sea bed for quite some time. The donor is a Warrnambool resident. Years ago he was cray fishing at King Island, which is in Bass Strait, northwest of Tasmania. His craypot got stuck in a reef so a diver helped him by retrieving the craypot for him. While the diver was underwater he also stumbled across the ship's wheel, which he gave to the donor. The Bass Strait is a very narrow route that was difficult and dangerous to navigate in the early 19th century, before good maps, communications and lighthouses were installed. The area, including King Island, is the graveyard of many ships that almost made it to their destination of Melbourne along Australia's treacherous coastline. Around King Island alone, many ships and lives were lost. There is no information about the history of this ship's wheel. Its condition shows that the item has been under the water for a long time. However, there is no evidence that it came from a shipwreck. It could even have been an old ship that could have been scuttled or destroyed as it was no longer useful. The wheel is significant as a sign of shipping around King Island. It is part of the island's history, and of maritime history. It is an example of an item manufactured by hand.Ship's wheel; segment of a wooden ship's wheel. It once had eight spokes but only portions of four spokes remain. The outer centres of the hub and the reinforcing bands around the hub are brass. The wheel is heavily encrusted in parts. It was recovered from an unknown shipwreck in the waters of King Island.great ocean road, warrnambool, shipwreck artefact, artefact, ship's wheel, ship's wheel segment, portion of a ship's wheel, flagstaff hill, maritime museum, maritime village, flagstaff hill divers, marine technology, navigation, steering wheel, eight spoke wheel, king island, craypot, diver
