Patent ID: 7125322

Claim:
Media transport device for transporting media from a storage hopper to a workpiece comprising a source of compressed air, a supply hose connecting the compressed air source to a mixing chamber, a blast hose connecting the mixing chamber to a nozzle dispensing the media onto the workpiece, said mixing chamber defining a flow path for the compressed air between the supply hose and the blast hose and including an inlet portion connected to the supply hose, an outlet portion connected to the blast hose, and a curved dispensing portion connected with said storage hopper, said curved dispensing portion curving obliquely into said flow path from an orientation generally transverse to said flow path, whereby said curved dispensing porion curves from an orientation permitting media within the storage hopper to drop into and travel through said curved dispensing portion into said flow path until discharged from the curved dispensing portion into said flow path at an oblique angle with respect to the flow path to introduce media from the storage hopper into the flow path at an oblique angle with respect thereto whereby turbulence of compressed air communicated through said flow path caused by media introduced into the flow path is minimized.
