Bellows
These wind-machines for foundry use are somewhat after the pattern of those used in the home, except that they are usually provided with hinges and made strong. The common ones are used for blowing away superfluous parting sand off the patterns, and loose sand and blackening out of the moulds. Bellows for the bench are made without spout and somewhat shorter. Special bellows, for distributing blackening upward where it cannot be applied with the bag, are now made; as also are sprinkling-bellows for saturating the mould, where necessary, with water, etc.
