Abstract

118,803. Bicknell, R. H. Aug. 15, 1917. Air-pressure sprayers.-Cementitious material is projected into a mould by spraying-cones 211. to which material is delivered through pipes 21 from a measuring-device 20 by a compressed-air nozzle, water being supplied by a pipe 221 to nozzles 22. Preferably dry material is forced through the pipes 21 and is moistened just before reaching the walls of the mould.
