identification | gas

The classification of gas street lighting lanterns follows the method used by W. J. G. Davey, B.Sc. and A. R. McGibbon, A.M.I.E.E in their paper Modern Gas Street Lighting Lanterns.



gas | square lamps

Square lamps, also known as Windsor lamps, were in general use for residential streets and for some arterial roads, being suitable for classes H, G and F of the British Standard Specification BS 307. The lamps may house cluster or alignment burners, and are generally fitted with some form of directional reflector.

The reflective devices themselves form a means of classifying such lamps.

gas | globe type lamps

Glove type lamps, either suspended or mounted upright on U-fixings, are more generally known, perhaps by the manufacturers' trade names, e.g. the Rochester (Sugg) and Stechford lamps. Incorporating up to fifteen mantles, they form an imposing an efficient gas street lighting unit, and are universally employed for Classes G to D of the British Standard Specification 307. (Note that lanterns such as the Supervia were available in both low and high pressure versions.)

gas | lamps with special mantles

These are all used on high-pressure gas mains. "The term "high pressure" is a comparative term only. With the introduction of the incandescence mantle nearly half a century ago gas pressure became at once a matter of great importance. At first 1½" of water column pressure was a suitable pressure forthe Welsbach light, but it soon became evident that better results could be obtained with higher pressures. Conditions changed when the inverted burner and mantle were introducted - 3" of water column pressure was desired. The important stage in the development of high pressure (or "intensified") gas lighting was when the gas pressure was raised to about 8" of water column pressure by mechanical contrivances - the earliest being water-driven pumps - to increase the velocity, and therefore the knetic energy, of the stream of gas issuing from the gas nipple orifice into the mixing tube of the burner. The energy of the higher pressure gas jet entrained a greater volume of air than was possible with the lower gas pressure and "this resulted in a hotter flame and a greater intensity in the incandescence of the gas mantle." - Street Lighting By Gas With Special References To The High Pressure system, Dean Chandler, M.Inst. Gas E, APLE Conference Folkestone 1937.
