ABSTRACT:
Shears are supported for reciprocating displacement within an open frame so that they can be conjointly displaced from retracted positions to advanced overlapping positions where a runner of molten glass will be severed. A pair of covers close the open frame except for the central portion where the runners pass through. A pipe having a plurality of holes is secured to the front edge of the covers so that coolant can be directed downwardly and inwardly against the reciprocating shears.
