Fillet
A rounded corner on a mould. There is less danger of shrinkage flaws when corners are filleted. Flexible metallic filleting, any size required, may be obtained at a nominal figure, so that no pattern need be left without. When fillets are left to be carved off by the moulder it costs twice the amount for labor, and, unless the operation is performed by a good mechanic, the result is invariably a botched job.
Filling in.--Setting the inside courses of bricks by the loam-moulder. In heavy walling and solid cores the faces or outer courses are built strong, but the filling-in courses are set wide apart and the spaces filled with fine cinders to lead away the gases. This is a very common term in a foundry. Placing sand inside a flask or any other receptacle, as a riddle, sieve, etc., is usually called filling in. See BRICKING UP.
