Abstract

151,692. Woolcock, J., and Stewart, W. J. June 20, 1919. Moulds.-In apparatus for moulding concrete products, for example blocks, panels, and conduits, wherein india-rubber or like material is used for the surfaces of the moulds or cores, the rubber surfaces are so arranged that when they are slightly contracted by removing their supports or by the tension necessary to remove them, they can be separated from the moulded surface by a sliding movement parallel thereto. Fig. 2 shows an arrangement for moulding building-blocks. A number of compartments are formed by longitudinal partitions c crossed by transverse partitions; in these the blocks are moulded, the corner shoulders being formed by rubber surfaces g backed bv filling blocks f, and the cavities are formed by rubber tubes supported internally by wooden or metal cores j, k, or by helical spring members m. n, or by gas or liquid pressure, the tubes in this case having a non-extendable lining. In moulding a pipe-line or sewer, concrete is put in a trench 1, Fig. 6, and blocks 3 are arranged to support rubber tubes 4 supported internally in the above-described manner. The conduit is moulded around these in limited lengths so that the rubber tubes can be withdrawn as described.
