摘要： Apparatus for replenishing a melt while a crystal growing operation is in process. The apparatus comprises an elongated hollow housing member having an open top end and a closed bottom end. A vertically movable support means for supporting a charge of source material, to be added to the melt, is located within the hollow housing member. The apparatus further comprises a conduit means for delivering a predetermined charge of source material to the support means. A charge of source material is delivered to the melt by operation of a retractor means that retracts the support means downwardly within the hollow housing member against the force of a spring means that yieldingly biases the support means upwardly within the hollow housing member towards the open top end of the hollow housing member. When the support means reaches a predetermined release point in its downward motion, the retractor means automatically releases the support means to the force of the spring means. Under the force of the spring means, the support means moves rapidly upward within the hollow housing member until it hits a stop means at which moment the charge of source material is projected into a deflector member which deflects the charge into the melt.
