Abstract
185,464. Edwards, H. T. May 4, 1921. Cores of such articles as pipe bends have prints so arranged as to prevent rotation of the core in the mould and dispense with the use of chaplets. The prints 13 are short and may be of semihexagonal form with the diametral plane in the parting of the mould.
