METAL VALVE FOR BATTERY GRID CASTING MACHINE

摘要

A valve for dispensing a predetermined amount of molten lead to the mold of a battery grid casting machine has two tubular housings arranged in telescoping relation with their axes extending vertically. The upper housing is fixed and has a feed line for molten metal connected thereto. The lower housing is vertically movable and has a lead discharge line extending therefrom. A ball valve member is loosely retained on a pedestal in the lower housing and is arranged to seal with an annular valve seat in the upper housing to control the flow of lead in response to vertical movement of the lower housing.
