This collapsible magic lantern is an early form of a slide projector, also known as the ancestor of the modern slide projector; used for projecting images painted on glass with translucent colors. Composed of a light source which, in the early lanterns was candlestick. The magic lantern was also known a a light projector of a positive image from a glass plate. These images were used for lantern slides and were traditionally drawn or stenciled on. This lantern can collapse in on itself saving two and a half times its original size.

"The circles for position angle and declination are read by micrometer microscopes illuminated by the lamp L; the scales are illuminated by the lamp l. T is part of the tube proper and turns with the head. The tube V, on the contrary, is attached to the cradle, and merely forms a support for the finder Q, the handles at f and p, and the moving ring P. The latter gives quick motion in position angle; the handles a p clamp and give slow motion in position angle, those at f clamp and give slow motion in right ascension and declination." &mdash;The Encyclopedia Britannica, 1903

"Suppose the mirror, a b, to be placed on the side of a room, and a lamp to be set in antoher room, but so situated as that its light would shine upon the glass. The lamp itself could not be seen by the eye placed at e, because the partition d is between them; but its image would be visible at e, beacuse the angle of the incident ray, coming from the light, and that of the reflected ray which reaches the eye, are equal." -Comstock 1850

"The moderator lamp, invented by M. Franchot about 1836, from the simplicity and efficiency of its arrangements rapidly superseded about all other forms of mechanical lamps. The two essential features of the moderator lamp are (1) the strong spiral spring which, acting on a piston within the cylindrical reservoir of the lamp, serves to propel the oil to the burner, and (2) the ascending tube C through which the oil passes upwards to the burner. The latter consist of two sections, the lower fixed to and passing through the piston A into the oil reservoir, and the upper attached to the burner. The lower or piston section moves within the upper, which forms a sheath enclosing nearly its whole length when the spring is fully wound up." &mdash;The Encyclopedia Britannica, 1910

"An example of a form of reading lamp is seen here. The lamp is mounted on a standard on which it can be raised or lowered at will, and fixed by a thumb screw. The oil reservoir is in two parts, the upper ac being an inverted flask which fits into bb, from which the burner is directly fed through the tube d; h is an overflow cup for any oil that escapes at the burner, and it is pierced with air-holes for admitting the current of air to the center tube of the Argand burner. The lamp is filled with oil by withdrawing the flask ac, filling it, and inverting it into its place. The under reservoir bb fills from it to the burner level ee, on a line with the mouth of ac. so soon as that level falls below the mouth of ac, a bubble of air gets access to the upper reservoir, and oil again fills up bb to the level ec, and so on it goes as long as combustion continues and the supply of oil in ac endures." &mdash;The Encyclopedia Britannica, 1910

Moving the reflector will render the sound inaudible." -Avery 1895

"The eye-end of a telescope. The reader will recognize the micrometer previously described. L is a paraffin lamp fitting by a bayonet joint into a copper cover c. This effectually defends its glass chimney against accident, and protects the lamp from wind. The simple means by which this lamp is made to preserve its verticality in all positions of the telescope is evident from the figure. By this lamp alone the bright wire or bright field illumination is given at pleasure, and with any desired intensity, simply by movement of the small pin p." &mdash;The Encyclopedia Britannica, 1903

Lamp trimmers were specialized onboard ships that involved maintaining oil lamps. In the days when light came from burning oil in lamps, a vessel at sea needed crewmen to constantly care for the lamps. This care involved trimming the wick, which drew the oil up from the storage reservoir, so that the flame would be clean and bright. Lamp trimmers also refilled the reservoirs, which held enough oil for several hours of burning, but not enough to start a major fire if the lamp were to be knocked down or damaged somehow. As vessels became larger the number of lamp trimmers increased significantly, because the only lighting below decks came from lamps. The position of lamp trimmer was so entrenched into marine tradition that electricians were called lamp trimmers for years after oil lamps had been completely replaced.
