Binder
The name given to almost every device used in the foundry for binding moulds together before casting, but in particular to the beams which rest over the copes of green and dry-sand moulds, as well as the covering-plates of loam-moulds, by which the upper portions of the moulds are made secure to the lower by means of clamps or bolts, in order to prevent any possibility of their being raised by the pressure of molten iron underneath them. See PRESSURE OF MOLTEN METAL.
