the connection 22 the connection 22 thus includes a suitable pin for engaging the tank and opening the tank valve as in conventional replaceable high pressure tanks a shutoff valve 30 is provided on the high pressure connection 22 in the form of a threaded tap which contains the high pressure within the tank when closed the trigger valve mechanism 28 is similar to conventional triggers for air tools and is mounted on the bottom end 18 of the pole the pole is continuous as a solid piece or in segmented pieces having fixed connectors so that the assembled structure has no moving parts turning now to the second embodiment of fig3 and 4 the conduit 26 comprises a hose which extends alongside the pole 12 separate therefrom the pole in this instance is telescopic by forming the pole in several sections slidably received within one another in which no pressure connections are required at the sliding couplings due to the conduit being separate from the pole the hose forming the conduit is flexible for accommodating variations in the length of the pole alongside which it is mounted a high pressure connection 22 is similarly provided in series with the conduit at the bottom end 18 of the pole and a similar shutoff valve 30 is provided for containing pressure within the tank the tank 24 however may be carried separate from the pole or maybe carried on the pole by a suitable pole connection 32 a clamp 34 is provided at the top end.
