Abstract
701,087. Casting-machines; processes. HOFER, O. May 29, 1952 [May 29, 1951], No. 13657/52. Class 83 (1) When molten metal is poured into a shallow trough 1 and thence into a mould 6 through a plug-controlled gate 8, turbulence, which may cause slag to be carried into the mould, is prevented by providing the trough with an upstanding dam 2 in front of the gate and by raising the plug 3 no higher than the dam. The plug is actuated by a lever 5 pivoted on a post 5<SP>1</SP>. The seating 13 of the plug may be hemispherical and may have a depending stem 15 which remains in the gate and acts as a guide-bar to prevent undue swaying of the plug. In another modification, Fig. 7, the lower end of the plug is bell-shaped as at 13<SP>1</SP> and the stem 12 has four fins 17.
