Consolidated Optical
by Victoria JL Fisher
Consolidated Optical formed out of several Canadian local optical firms in 1907 under Lionel Amsden, formerly the secretary of The Cohen Bros. Ltd., a highly-successful Toronto spectacles and ophthalmic instruments company active since 1894. Amsden seems to have been involved in many of the Cohen Bros. Ltd.’s forays into more scientific activities, including an ophthalmic training college. Around 1909, Consolidated Optical hired a British instrument maker, Thomas Pocklington, a relative of Amsden’s, and added a survey instrument manufacturing business to the portfolio.
During at least 1913-1924, the company made a range of surveying instruments with optical components: transits (theodolites), levels, mekometers (range finders) and clinometers. They also appear to have made instruments connected with lens grinding. Some instruments by Consolidated Optical are also marked “Tycos”, the trade mark of American compnay Taylor Instrument Co., but the company was definitely manufacturing from scratch. From 1910 to 1924, the company boasted a large factory on Richmond Street West.
As the company's most experienced instrument maker, Thomas Pocklington was in charge of instrument manufacture. He kept notebooks that offer insight on the components necessary to construct the instruments the company sold, their costs (either from purchase or supplies), and the costs involved in the assembly of the instrument. The company's offerings included five types of Wye levels--an instrument designed for measuring horizontal angles. The "Consol" brand Wye Level is listed as requiring 19 3/4 hours of final assembly work on top of the construction of sub-components, hinting at the complexity of these instruments.
The company was likely buoyed by sales during the First World War where items such as clinometers were in use by the military. However, it is not clear to what extent such instruments were manufactured on site. Following the war, Consolidated Optical seems to have had an important presence in Toronto in the early 1920s. In 1921 or 1922, they were contracted to manufacture the camera for the 1922 Eclipse trip to test Einstein’s Theory of General Relativity, suggesting they were known to be at a university standard for precision.
This surveying instrument section of the business survived until 1924, when it was bought by J. Frank Raw Ltd., another Toronto company. The company continued selling spectacles and doing a retail business in various instruments, and was either purchased or became associated with American Optical Company of Canada, a large and similar American company with manufacturing operations in Nicolet, QC and Belleville, ON. Between 1933 and 1947, these sites operated under the name Consolidated Optical. After that, the name reverted to American Optical Company of Canada (later AOCO).
The demise of the company's foray into survey instruments resulted in Thomas Pocklington beginning his own instrument-making business, one that was continued by his son and grandson throughout the 20th century as Thomas Pocklington Ltd..
