This firm was one ...Theodolites have been used to measure horizontal and vertical angles by surveyors since the 1500s. A theodolite is a precision instrument for measuring angles in the horizontal and vertical planes. Theodolites are used mainly for surveying applications, and have been adapted for specialized purposes in fields like meteorology and rocket launch technology. Theodolites, such as this one, were instrumental to early surveyors, and would have played a significant part in their everyday work. The plumb bob was used to set the instrument exactly over a fixed survey marker.This theodolite was made by Troughton and Simms, who were significant scientific instrument makers of the 19th century and early 20th century. In 1782 John Troughton purchased Benjamin Cole's shop in Fleet Street, London enabling him to sell his own signed products. His instrument making business supported several dynasties of Troughtons before becoming Troughton and Simms and later still Cooke Troughton & Simms. This firm was one of the most well respected firms of instrument makers of the 1800s. A grey metal theodolite - probably made of brass. It has movable parts and there is a weight ( a plumb bob) attached with string.Cooke Troughton & Simms Yorke England V012318 Supplied by A. E.

Cooke Troughton & Simms began when John ...Theodolites are a highly accurate instrument that measures angles between designated visible points in the horizontal and vertical planes. The theodolite has a long history, with the term first found in 1571 in a surveying textbook 'A geometric practice named Pantometria' by Leonard Digges. (source https://en.wikipedia.org/wiki/Theodolite). Cooke Troughton & Simms began when John Troughton starting selling products in Fleet Street, London in 1782. He went into partnership with his brother Edward in 1807 who expanded the business considerably. William Simms, a former apprentice with the company was taken as a partner and then manager after Edward died in 1835 and the company became Troughton & Simms. By 1887 the company was able to produce all the parts necessary for their instruments and the company employed nearly 200 people and was one of the most well respected firms of instrument makers of the 1800's. James Simms, son of William who had inherited the company died in 1915 and the company was turned into a limited liability company by his two sons William and James. Things however were not so easy for the two sons and in 1922 the business was brought out by their rival T. Cooke & Sons becoming Cooke, Troughton & Simms. Theodolites are used by surveyors as part of their everyday work and although there is no specific information regarding the provenance of this particular one it is assumed it was used locally by the City of Bendigo and / or the Lands Department.A grey theodolite no 39161 made by Cooke, Thoughton & Simms.

... Corps standard Cooke, Troughton and Simms Tavistock or Wild T2... Corps standard Cooke, Troughton and Simms Tavistock or Wild T2 ...A School of Military Survey Precis, 8 x foolscap sized pages of typed text, stapled and two hole punched. The precis No 3 covers the Observation procedure to be used for 1st, 2nd and 3rd Order Triangulation using the Royal Australian Survey Corps standard Cooke, Troughton and Simms Tavistock or Wild T2. The geodetic model Tavistock with a 5.25" horizontal circle should be used for 1st Order Triangulation and maybe used for 2nd Order Triangulation if specially directed. The standard Tavistock with 3.5" horizontal circle or the Wild T2 should be used for 2nd and 3rd Order observations. The Precis discusses the types of errors, the source of errors and the best ways of managing them. In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline by using trigonometry, rather than measuring distances to the point directly as in trilateration.A School of Military Survey Precis, 8 x foolscap sized pages of typed text, stapled and two hole punched.royal australian survey corps, rasvy, fortuna, army survey regiment, army svy regt, asr, school of military survey, sms, balcombe -
