The sheeisurfaces are also shown shaped outwards, at D, so that, when put together,these elevations meet one another, and form a flame bridge, as shown inthe Plate (325). Fig. 4 shows a very simple method of forming tinsheet surfaces; each plate has one end shaped and the other end plain,when, by turning them end for end, the requisite space is obtained, withonly half the amount of furnace work—a most important consideration asregards the :~7
