This is a continuation of the last posting subject. Look at that for more pictures of rare lamps
Here are a selection of the long, short and the tall, and heavy!!
The grooup pic is for comparisons. The tallest is the ETW Carbide Shaft Lamp at 1'-9" tall. The heaviest and biggest is the Ellis Shaft Lamp - Big Bertha - at 14 lbs - one stone!!!!!!!!!!! And the smallest working Lamp is the ETW No 10 at 4.5" tall. Thrown in are the petrol cigarette lighter at 2.5" tall (value £5!) and the key ring lamp at 1.25" tall (value £2!!).
The lamp on the right is a Yates Patent and is the normal lamp size just to illustrate the variation in sizes.
The Ellis Shaft Lamp is BIG. 14 lbs wieght, 1'-5" tall excluding hook and 7" diameter. A brass and steel construction with a screw side lock and ellis burner. Interestingly there is a post code stamped on the top and this turns out to be the house of the former Lamp Room manager of a local Wakefield pit. Value around £5000.
The small round piece on the bottom right hand side of the dismantled image, is the oil vessel from the ETW miniture No10, just for illustration of the two spectrums of size!!!!
The ETW Carbide Shaft Lamp is TALL. 1'-9", 5.5" in diameter. Brass and steel construction, with hasp vessel lock and side screw bonnett lock.
Water, from an upper tank in the base, is dripped through an adjustable needle valve (this controls flow of water and speed of gas production) onto carbide crystals in the bottom tank. Flammable gas is produced and jets through the yoke burner wher it is ignited. The lamp is then locked and sent down the pit. Value around £3500
Yates Patent 1871 Clanny. All brass construction. A half circular magnifying lens with a reflector at the back of the flame. Presumably would be a surveyors lamp. Only three known to exist. Value around £5500.
G. D. Scott of Newcastle Baby Clanny with dioptric lens.
Lovely little lamp from a rare manufacturer. All brass construction with copper gauze and screw side lock. Only 7.5" high and 2.5" in diameter. Value around £1000.
