Slide rules were commonly used prior to the invention of the calculator. The Slide rule was used for performing multiplication, division and other scientific functions up through the 1960s and prior to the development of the electronic calculator. Used by Frank Smythe, engineer. Used up to the 1960's prior to the invention of the electronic calculator. Metal rule, hard cardboard case. The slide rule consists of two divided scales, one fixed and one movable, and a sliding window called a cursor.

The Stanley Works was founded by Frederick Trent Stanley in 1843, originally a bolt and door hardware manufacturing company located in New Britain, Connecticut, USA. The Stanley Rule and Level Company was founded in 1857 by Henry Stanley in New Britain, Connecticut. In 1920, this company was independent from Trent Stanley's works but they merged with the separate but related Stanley Works, that was founded by Henry Stanley's cousin Frederick Trent Stanley, and continued operating as its hand tools division. At this time after the merger the “Sweetheart” Trademark was adopted for tools made between 1922 to 1935 with augers manufactured during this time having the “AA” trademark and this is when the Stanley company we know today came into being. Around 1937, Stanley acquired the British J. A. Chapman company, a British manufacturer of carpentry tools and other items (including bayonets during World War I) formerly located in Sheffield, from Norman Neill. This helped Stanley to enter the British market.A early tool manufactured by an emerging company that today produces tools for sale in just about every country in the world.

Decimal currency was spectacularly introduced in an overnight overthrow on 14 February 1966, but it took another 8 years before metrication finally arrived in the forest and timber industry. Eventually, the measurement of logs and sawn timber changed from imperial, and excruciating, measures such as super feet of sawn timber, billets and cunits (100 cubic feet) of stacked pulpwood and hoppus log volumes to simpler cubic metres. Measuring firewood was a particular nightmare. For example, there were standard chords, stove cords, kitchen cords, running cords, face cords, thrown chords, fencing cords, country cords, long cords, raummeter or steres (1m x 1m x 1m). A standard cord of firewood had a volume of 128 cubic feet, measured as a pile 8 feet long, 4 feet high and 4 feet wide (3.624 m3). And how about this for confusing…. in Victoria, an imperial or long ton (by measure) of green firewood was a stack 5 feet long billets (2 axelengths at 2′ 6″ each), one axelength high (2′ 6″) and two axelengths long (5 feet) equalling 62.5 cubic feet. For added befuddlement, there were three different sorts of tons: Imperial tons or long tons, American short tons and metric tonnes (spelled with two n’s). Not forgetting that a cubic imperial ton of firewood (40 cubic feet) which equalled 1.133 cubic metre. The metrication process began in 1974 and was completed by 1976 but the transition was not without its challenges along the supply chain for foresters, overseers, logging contractors, sawmillers, hardware stores and builders alike. Timber lengths changed from feet to metres but were still sold in multiples of one foot or 0.3 m (1.8, 2.1, 2.4, 2.7 etc) whereas a menacing lump of 4-Bee-2 transformed into a rather less colourful 100mm by 50mm. Measurement and calculations of area also became so much easier in hectares rather than complicated acres, roods and perches. The Forest Metriverter slide-rule was issued by the Forestry and Timber Bureau to make metric conversions easier.Forest MetriverterRoss Pennyforest measurement, surveying, forests commission victoria (fcv)
