The presentinventionrelates to conveying and hoisting apparatus and is designed especially for use in charging iron,"coke and othermater'ials-into 'a foundry cupola. In

the 'opferationof a cupola' it is .desirable to" collect the material from storage spaces and depositit in the cupola as economically and with as little labor as posslble. It is also desirable to drop the material centrally in the 'cupola onto/the fuelbed inorder to distribute the-material evenly and to prevent bridginganduneven accumulations of material i'n the lower part ofthe cupola: In many foundries local conditions make itimp'ra'ctical so to design the Zapparahis that the V charger by "which the niater'ial is deposited in the cupola may travel to a distant storage space 'tocollect'mater-ial; and in such situa'- tions "it is desirable that the charger be capable of collecting material from"as'exten-,.

trollers mounted in cage carried 5 the charger '2 as diagrammatically illustrated in Figure 1. "The motors may; if"d'es'ired;' becontrolled' by anoperatorwnfthe floor by means of depending cables orythey 'may b'e con-trolled from a-sin'gle fixed station, such: as a pulpit, from which" the operator may I. .7 it i l. .Hl -v observe the cupola and the ent-ire operating In operation the track-3 will 'be rotated" and the charger will be moved along the track until the carrier at the forward end of the charger is located over-the material bed- :Although the entire apparatus is relatively compact'the invention makes it possible to collect material from an extensive storage area by rotation of the track 3 through an angle of three hundred and sixty degrees or more and by travel of the charger diametrically of the circle. The rotation of the v track, the travel of. the charger and the operation ofthe hoisting drum, as well as the control of the magnet when one is used as the carrier, may beconveniently and centrally controlled preferably by an operator in the cage carried by the charger. The detailed constructionby which the track 3 is rotatably supported by the frame andby the circular track provides notonly for simplicity of manufacture of theparts involved, but for very easy assembly of the apparatusand for very sturdy support of the charger. Having thus described my invention, whatI claim is: 7
