A cupola installation having a top charging opening and a vibratory feeder mounted to discharge into the top opening from one side. The skiphoist associated with the cupola carries two charging buckets, one for discharging charge material into the top charging opening in the stack while the other is for simultaneously discharging material into the pan or hopper of the vibratory feeder. When the empty charging buckets are lowered, the vibratory feeder is operated to discharge its load into the top charging opening. The use of two charging buckets permits a charge material of a type not suitable for charging along with the main charging material, to be separately charged in a gentler manner. For example, briquettes of cast iron borings and chips or of steel turnings are easily broken into objectionable fines when handled and charged in a conventional manner. Cooperating equipment associated with the trim platform assists in the loading of charge material into the separate charging buckets. The invention resides both in the novel charging apparatus and the novel method of charging material into the cupola.
