Abstract

292,425. Roberts, E. W., and Temple, J. E. Dec. 23, 1927. Moulds.-A collapsable core for use in moulding hollow concrete blocks comprises a hollow shell built up of a base portion 2 and two hinged angle pieces 3, 4 which form the top and side walls. The abutting surfaces of tfiese members are bevelled at 6. A prop or strut 13 hinged to the base, which is turned upwards to support the top wall during use, allows the top and side walls to collapse when it is turned down into the position illustrated in Fig. 3. The corners 14 are rounded sufficiently to clear the moulded block during the collapsing operation. Fig. 5 shows a modified construction for floor units. In this case the angled members tip in collapsing about the base members 14<1>, the sharp edged fulcra on the members 4 acting as hinges. Loose strips are used as props instead of the hinged prop 13.
