Belt-core
It is common to call almost any description of jacket-core by this name. See JACKET-CORE.
Belts for cores.--Leather-belting makes very reliable and handy slings for lifting cores, but, owing to the very inferior means usually provided for binding the ends together when in use, very much of their reliability and usefulness is marred. If very thin steel ends are riveted on, all this annoyance is obviated. The steel, 1/64 inch in thickness, must be just as wide as the belt, and as short as is consistent with safety. The ends, being both turned with a very short "U," interlock each other.
