Not illustrated. 1902 edition. Excerpt: ...X Tv in., and two smaller ones A in. x-A-in. close to the sides and opposite each other. These three holes may be closed and uncovered by means of a slide moving in grooves, and having perforations corresponding to those on the lid. In moving the slide so as to uncover the holes, the oscillating lamp is caught by a pin fixed in the slide and tilted in such a way as to bring the end of the spout just below the surface of the lid. Upon the slide being pushed back so as to cover the holes, the lamp returns to its original position. Upon the cover, in front of and in line with the mouth of the lamp, is fixed a white bead, the dimensions of which represent the size of the test flame to be used. The bath 01 heated vessel consists of two flat-bottomed copper cylinders (24 B.W.G.), an inner one of 3 in. in diameter and 2 in. in height, and an outer one 5 in. in diameter and 5f in. in height; they are soldered to a circular copper plate (20 B.W.G.) perforated in the centre, which forms the top of the bath in such a manner as to enclose the space between the two cylinders, but leaving access to the inner cylinder. The top of the bath projects both outwards and inwards about f in., that is, its diameter is about f in. greater than that of the body of the bath, while the diameter of the circular opening in the centre is about the same amount less than that of the inner copper cylinder. To the inner projection of the top is fastened, by six small screws, a flat ring of ebonite, the screws being sunk below the surface of the ebonite to avoid metallic contact between the bath and the oil cup. The exact distance between the sides and bottom of the bath and of the oil lamp is % in. A split socket, similar to that on the cover of the oil cup, but set at a right...show more
