All ladles should be frequently,regularly, and critically examined, and when defects areobserved the ladles in which they are found should beimmediately set aside for repairs, or should be discardedif the defects are of a serious nature. Reservoir ladles and all other ladles operated bygearing should receive special attention. The motorsof motor-operated ladles should be completely inclosed,not only to protect the workmen against electric shocksand burns, but also to prevent accidents which might becaused by metal being spilled upon the motors, re-sulting in short circuits or other kinds of trouble.

Fig. 1. A Crane Ladle. (The gears should be completely inclosed, to prevent them from becoming clogged with dirt and spattered metal.) not provided the gears will soon become clogged withdirt and with metal that has hardened or set after hav-ing been spilled upon them while in a molten state;and clogged gears are likely to be broken or stripped,and to cause serious accidents. LADLES 7 Many ladles are equipped with direct-acting spurgears. This arrangement permits rapid operation ofthe ladles, but it often imposes severe strains upon theoperators, making it difficult for them to hold the ladlessteady while pouring. This often results in spilling themetal and causing it to be spattered about when itstrikes the sand on the tops of the flasks. A tilting ar-rangement composed of a train of spur gears, or a com-bination of worm gearing and spur or bevel gears, isto be preferred. The gears should be so designed andarranged that at least two teeth of each wheel will bein mesh at all times. Unsafefoundrypract01trav
