Abstract

172,855. Clarke, E. G. Nov. 24, 1920. Moulds.-A mould for use in moulding blocks or slabs is formed with three sides d, e, f hinged together as one member, the other side g being independent and having notches p to engage with projections on the ends of the sides e, f. The mould is made adjustable in length by making the hinge member n adjustable in the side d, packing being used to make the mould narrower. The pallet comes partly under the mould side d and the removable side closes the mould and is held by cam bolts or wedges.
