Abstract
A nozzle assembly for a tool which utilizes a particulate/fluid mixture comprises a unique floating ferrule within a handpiece assembly, and eliminates the need, in the prior art, for a nose piece to attach a nozzle to the handpiece assembly. Rather, the nozzle and its integral holder are designed so that a hose may be slipped over its extended rear tube and then, when the handpiece with its floating ferrule is twisted on, the hose is captured and sealed. This is managed because the ferrule is unengaged when the handpiece tube is first started to be threaded onto the nozzle holder. After a few turns, the ferrule pushes against the hose and seals it against the rear extension of the nozzle holder. When the handpiece is unscrewed from the nozzle, because the nozzle must be replaced, the ferrule remains attached to the nozzle and hose, allowing for easy turning. Once the handpiece is unscrewed from the nozzle, the nozzle may be tipped slightly to disengage it from the hose very easily.
