The patterns from which the castings for brasses are moulded should not be made of the same angle or sweep on the bedding part or bottom as the bottom of the box, pedestal, or pillar block, because the brass casting, in cooling in the mould, contracts across the bore; thus if in [Figs. 2434] and [2435] the full lines denote the shape of the pattern the dotted lines denote the shape the casting will be.
