Summary
Lanternist's carbon arc lamp with protective glass. This is a metal construction. There is a hole at one end to mount the lamp on a post and a brass thumb nut to secure. There is a coil of wire connected by electrical connectors to the base of the lamp. There is a circular base plate for the actual lamp mounted above. The carbon rod which enters via the centre of this plate is controlled by a rack and pinion system which was insulated by a rubber cover and a rubber knurled handle. Attached to the circular plate is a brass construction with a further electrical connection point, two plates with holes in the centre which appear to take the other carbon rod and introduce it through a hole in the protective glass. Thereis a two claw lever mounted below, again with an insulated handle. There are two brass rods which support the lid of the lamp. This has what appears to be another electrical contact point, is of heavy metal construction and has embossed "Patent 9225 1910".
