Seating
A guide-bearing or rest for cores or mould sections. In vertical loam-work the cope or the core, and sometimes both, are made as separate portions of the mould, and must be lowered into their respective positions when the mould is closed together in the pit. In order that this may be done accurately, a tapered seating is formed at the bottom of the mould, extending some few inches below the casting. By this device the smallest end of the core is made to enter at the widest diameter of the seating, and is thus guided to the bottom-bearing, when the sides meet close together at a true centre. The cope is the opposite to this, its widest diameter seeking a true location by inclosing the small end of the seating first, and gradually embracing it closer and closer until the bottom-bearing is reached, when the diameters correspond and the section is central. The tapered sides of an ordinary core-print represent the seating for a core. See COPE-RING; PRINT; GUIDE.
