Title: Improvement in method for the production of patterned articles from moulding powdersof all kinds
IPC: B29C41/22
Filed: 1937-06-16
Abstract: 490,790. Moulding powders centrifugally. SCHAFER, H. June 16, 1937. No. 16785. Convention date, June 17, 1936. [Class 87 (ii)] . Articles having a mottled or patterned ornamentation extending throughout the article are moulded by distributing differently-coloured powders in layers by centrifugal action within a rotating mould a. The powders may be subjected to heat or pressure or both to complete the moulding. A pattern in concentric rings such as an imitation of natural horn or wood may be produced. The mould a may be formed with a rotary hollow shaft b through which passes a shaft f carrying a piston d forming the bottom of the mould. A cover g may be provided having a feed opening h. In use, the piston is set to adjust the size of the mould and layers 1, 2, 3 are successively introduced and formed. A core 4 of loose or preliminarily-pressed powder is finally inserted. The assembled powders may be pressed by the piston d. The pattern is varied by speed of rotation. For moulding discs, the shaft may be vertical and for rods, horizontal. Insertions which may consist of lightly compressed powder may be provided between the layers or to produce special effects and the insertions may themselves be formed by centrifugal action. The Specification as open to inspection under Sect. 91 comprises also the formation of oval bodies by lateral pressure on the shaped rod. The rod may be divided into discs which are used to form buttons. For other shapes, the mould may be rotated about an inclined axis. This subject-matter does not appear in the Specification as accepted.
