ABSTRACT:
Apparatus 10 for discharging particulate material such as sand has a container 11 for the material, a supply conduit 20 for pressure gas, e.g. air, connected to an inlet 16 and via pipe 17 to an outlet 12 and a flexible discharge conduit 14 leading to nozzle 15. Flow in conduit 20 is controlled by a manually operable valve 21 biassed closed and when open gas and particulate material flow forcefully through nozzle 15. All the gas goes through valve 21. The apparatus can thus be controlled by an operative remote from the container 11 without consumption of pressure gas when valve 21 is closed. The valve 21 is mounted for convenient operation by a user. In a modification the valve 21 is nearer the container and operated from near the nozzle through a mechanical connection.
