Abstract

1535385 Spray-producers F W LANCASTER 5 July 1977 [16 July 1976] 29812/76 Heading B2F A gun produces a stream of chopped fibres from a conduit 10 after passing through a Venturi 19 containing air ducts 20, and a stream of cementitious material from a nozzle 30 arranged coaxially in the conduit 10, the two streams merging downstream of the gun. The nozzle 30 is supplied by a conduit 26 which passes through the wall of the conduit 10 and contains an air jet tube 33 which is axially adjustable by a cam 34. Operation of air valve 39 also initiates operation of the pump supplying conduit 26 and a trigger operates both the fibre cutter and initiates air supply to the ducts 20. Nozzle 30 is held in position by a bayonet fitting and conduit 26 may be removed for cleaning by operating a catch 46.
