Calipers like these were commonly used in the 19th and early 20th centuries for precision measuring tasks, particularly in blacksmithing, metalworking, and carpentry. Their adjustable design allowed craftsmen to accurately check external dimensions of objects such as wheels, barrels, or machined parts. These outside callipers would have been especially useful for ensuring uniformity in metal or wooden components, a crucial aspect of engineering, manufacturing, and blacksmithing practices before the widespread use of digital measuring tools.The item is a pair of large iron dividers or outside callipers, used for measuring external dimensions or transferring measurements in metalworking, woodworking, or blacksmithing. The tool consists of: Two curved arms forming a symmetrical, oval-like shape when opened. A pivot joint at the top, allowing the arms to move freely for adjusting the measurement range. A flat adjustment screw mechanism, which helps in finely tuning and locking the calipers in place. The metal surface is darkened and rusted, indicating significant age and long-term use.farm equipment, callipers, measure

Used for polio patient for sleeping - to stop the legs turning over. Polio disability aid. Callipers were fitted to lock up the knee joints of weakened leg to enable a person to walk without their legs collapsing and to pick the foot up from the ground when foot drop had occurred due to paralysed skin muscles. The polio patient found these devices restrictive and uncomfortable. See KVHS 1796, KVHS 1798Used by Wilma Davies, a Kiewa Valley resident, who suffered from polio from the early 1950s.Metal frame for each leg to fit in a 'V' shape from the waist to the feet. Supported by canvas straps - 3 on the left side, and 2 on the right (1 has been torn off and replaced with leather straps). 2 flat foot shaped steel plates are at the foot end and are adjustable for the feet to be at several angles. The frame has a supporting frame attached giving depth to the calliper.polio, calliper, pandemic

Used by those wishing to make bullets and ammunition. Lead would have been used to make the shots with this tool.Rusted iron shot mould with two handles similar to callipers. There is an oval shaped ball of metal at one end which opens in the middle to allow molten material to be placed inside for casting into lead shot. There is a hole at the top of the oval ball which allows the molten metal to be poured in. Once cooled the oval is opened up and the shot can be removed. The object is heavily rusted.artillery, weapon, ammunition, battery, portland battery

Established in 1906, Frank Moore soon became well known amongst discerning tradespeople for the quality & accuracy of his tools. The Company was acquired by John Shaw & Son in 1945 & James Neill & Co in 1970. Currently part of the Bower Meteorology UK Group, they still produce superb tools & measuring instruments in Sheffield. The subject item is made from high-grade carbon silver tool steel with the patented 'Firm Lock' joint, that identifies the maker as Moore & Wright.A tool used for external measurement of items made by a maker who patented the "firm lock" jointing system now used on many different types of tools in many different industries. These items are now collectible and quite rare as a result are sought by tool collectors in the USA and UK.‘Firm Joint’ external measuring calipers believed made by Moore & Wright.

This set of calipers was used for measuring widths or thicknesses in the planning and making of components for the ship model Sovereign of the Seas. It is part of a collection of objects used by Jim Williams, maker of fine ship models from about 1930-1955. Most of the components for the models, as well as many of the tools, were handmade by Jim Williams. Jim’s family has donated the ship model “Sovereign of the Seas” and many tools, accessories and documents used in the making of this and other ship models have been donated to Flagstaff Hill Maritime Village. Ship model of HMS Sovereign of the Seas, scale model of 17th Century English war ship, was handmade and carved from plans, enclosed in airtight glass case. All components of that model, including even the smallest pulleys, were hand crafted using tools designed and made by Jim. Outstanding details include functional rigging and moving cannons. Please see our record 3732 of the mode Sovereign of the Seas for further details of the ship and the maker. This calliper is connected with the hobby and skill of ship model making that has been crafted as a leisure activity for many generations. The hobby is often chosen by serving and retired mariners who appreciate the connection with maritime history. This calliper was used by local Warrnambool man, Jim Williams, who was employed at Cramond and Dickson clothing store, and then at Fletcher Jones menswear for 27 years. It was used in making components for the model of the historic ship, the Sovereign of the Seas. The Sovereign of the Seas was a historic 17th century English war ship with important maritime heritage.Calipers, metal, two curved arms joined at the top to open and close. Spot of orange paint on one arm. Used to measure thickness of materials.

1833 Brown & Sharpe was founded in Providence, Rhode Island by David Brown and his son Joseph R. Brown. David Brown retired in 1841 and Joseph Brown formed a partnership with Lucian Sharpe in 1853. During the 19th and 20th centuries, Brown & Sharpe was one of the best-known and most influential machine tool builders and was a leading manufacturer of instruments for machinists (such as micrometers and indicators ) and helped establish: The American wire gauge (AWG) standards for wire; The Brown & Sharpe taper in machine tool spindle tapers; and The Brown & Sharpe worm threadform for worm gears. .Like most machine tool builders, Brown & Sharpe rode a business cycle roller coaster during 1920- 40. After being kept very busy during World War I, builders suffered a slump in the post–World War I recession and depression of 1920–21. The Roaring Twenties brought renewed sales, but then the Great Depression slashed them. The armament-build-up period of 1936 to 1940 again renewed machine tool activity, and then the World War II materiel effort exploded demand, pushing it to record heights and employed 11,000 workers. Brown and Sharpe machine tools were a mainstay of American metal manufacturing until the late 20th Century and could be found in most machine shops and factories that worked with metal. Brown and Sharpe made callipers and micrometers that were essential to products built to fine tolerances. Shortly after World War II, Henry D. Sharpe, Jr. succeeded his father as president of Brown & Sharpe Manufacturing Company, at which point it evolved into a new and modern company built, or at least designed, to last. The firm stopped producing its old stalwarts: sewing machines, hair clippers, and certain categories of machine tools and employment dropped to 3,500 in 1976. Due to industrial disputes in the 1980’s B&S started focusing more on developing Coordinate-Measuring Machines. The company began to lose money as it shifted production away from machine tools and toward advanced metrology equipment, losing $14.6 million in 1990 and employed only 700. In 1994 Brown & Sharpe acquired DEA of Italy, an established manufacturer of CMMs. In 2001, substantially all of the assets of the Brown & Sharpe Manufacturing Company, including the intellectual property, designs, trademarks, facilities and inventory, were acquired by Hexagon AB, Switzerland, without the acquisition of the Brown & Sharpe Manufacturing Company itself.
