In building ovens, the builder or designer sometimesseems to have thought all that was required was a fire-placeand a space to pile cores in ; whereas, with a little morethought, they might have had an oven that would have beena success, and have cost no more than the apology for one. The revolving oven, shown in sectional elevation (first il-lustration), is round, with an upright cast-iron shaft, hav-ing five flanges on which to bolt plates or arms X, X, theshape of which is shown at B. This oven is built with an8 brick wall to form the outside, and a cast-iron plate forthe top, on which is a box, Z), to which a cap can be bolted, tohold the top of the shaft, the bottom of which rests in acast-iron seat.

When startinga fire both dampers should be open, and when the cores to bedried are on the top shelf, the bottom damper may be closed,and vice versa.

Should you want to dry asingle core quick, put it on the top shelf, and turn it aroundto the fire. This oven can be filled with cores, and theycan be taken out again without going farther than the door,which alone is of great value to a core-maker.
