Beginning in the late 17th century, English insurance companies maintained private fire brigades that were paid to respond to fires at properties they insured. Properties were identified by leaden badges (fire marks) bearing a insurance company’s emblem and often stamped with the customer’s policy number.
The Birmingham Fire Office Company of Birmingham, England issued this copper fire mark between 1805 and 1867. The circular mark features a raised image of a fireman alongside a hand pumped fire engine. Underneath the image is raised text that reads “Birmingham.” The company was founded in 1805 and operated until 1867, when it was taken over by the Lancashire Insurance Company.
A bicycle pump made of cream celluloid with metal fittings. It was made in England. A trademark etched into the barrel depicts a man in Elizabethan clothing holding a shield with the letters "R I."
In a constant deviation spectrometer, the collimator and telescope are fixed in place, and the observed wavelength is varied by rotating the prism or diffraction grating in the central box. The “ADAM HILGER LTD / LONDON / ENGLAND” inscription on the eyepiece of this example identifies the manufacturer. The “JAMES G. BIDDLE / PHILADELPHIA, U.S.A.” inscription on a brass plate identifies the firm that brought the instrument into the United States.
Adam Hilger, Ltd. introduced its first constant deviation spectrometer in 1904, noting that the prism was designed by Messrs. Pellin & Broca, and described in the Journal de Physique in 1899. The form proved remarkably successful, and remained on the market for decades. This example, made between 1914 and 1926, is a Modified Wavelength Spectrometer. Here, the arm between the collimator and the prism is designed to hold one of three high-resolution, multiple-beam interferometers: a Michelson echelon diffraction grating, a Lummer-Gehrcke parallel plate, and a Fabry-Perot etalon.
