Abstract

140,158. Peters, F. Jan. 28, 1919. Moulds.-In apparatus for moulding concrete blocks of the type in which the mould is given an up-and-down movement for allowing blocks formed therein to be easily removed, the moulds are arranged in pairs, one mould moving downwards while the other is moving upwards, and means are provided for varying the size of the mould; an inner lining also is provided. Fig. 2 shows one of the moulds 3 having a fixed base 1 and sides movable by cranks on the shaft 8. Cores 17 are also mounted on the movable framework so that they may be withdrawn from the moulded block when the mould is lowered. The size of the moulds may be varied bv means of side plates carried by screws 19. A lining may be provided Composed of two parts which, when the mould has in part descended, are clamped together by a metal band, after which the descent of the mould is resumed. To enable smaller blocks io be moulded, the mould is provided with a false bottom comprising a series of projecting plates with spaces intervening in which project depending plates carried by a frame attached to the movable parts of the mould. The projecting plates of the false bottom may be hinged to enable the blocks to be moulded with an inclined underside.
