Abstract
198,783. Alwyn, L. March 10, 1922. Moulds. - Standard sectional moulds for the formation of concrete columns, bodies and the like, more especially for use in the centrifugal-casting method, are formed alike from a master mould. The master mould 1 is formed of slate or other hard material and is covered by electrodeposition with a surface plate 4 of copper and the concrete is placed thereon and secured by an angle plate 5 and bolts 3. When set the copper face adheres to the concrete mould which is removed and the operation is then repeated. The mould sections are combined' as shown in Fig. 4 and secured together by bolts 12. The sections may be reinforced by metal rods if desired. The sections may be provided with any desired configuration to produce mouldings, dadoes &c. In some cases the moulded articles may be divided into halves by the insertion of dividing strips in the mould. According to the Provisional Specification the metal face may comprise a thin metal sheet pressed on to the matrix.
