ABSTRACT:
A stopper device for use in molten-metal auto-pouring apparatus comprising an attachment part constructed to be releasably fixedly attached to a stopper device operator of such apparatus and a stopper support part adjustably connected to the attachment part so as to permit a degree of movement therebetween. Locking means are provided to enable the stopper support part to be retained in a given position relative to the attachment part. As a result, when the device is prepared for use, and the attachment part is fixedly attached to such an operator, the latter operates to move the device downwardly so that a lower end of a stopper mounted on the stopper support part engages the outlet of the apparatus, the said degree of movement enabling that end to be seated properly in the outlet, whereupon the locking means are used to retain the resulting position of the stopper support part relative to the attachment part to ensure that the stopper will be properly seated after subsequently being raised and lowered.
