Claim Text:
1. An attachment for a spraying device to permit spraying an atomizable substance into hard to access areas to be coated by said atomizable substance comprising: a coupling device having a first side, a second side and a bottom side, said bottom side perpendicular to said first side and said second side, said first side adapted to connect said attachment to a spraying device, a first elongated resilient hose having a first side and a second side, said first side of said first elongated resilient hose connected to said second side of said coupling device, said first elongated resilient hose having a second resilient hose disposed internally, said second resilient hose having a first side and a second side, said second resilient hose first side is connected to said spraying device allowing said atomizable substance which leaves said spraying device to flow down said second resilient hose, a nozzle connected to said second resilient hose said second side, and a removable nozzle support centrally supporting said nozzle inside said removable nozzle support, said removable nozzle support having a first side and a second side, said removable nozzle support said first side removably connected to said first elongated resilient hose said second side, a third elongated resilient hose having a first side and a second side, said third elongated resilient hose perpendicular to said first elongated resilient hose, and said third elongated resilient hose said first side connected to said coupling device bottom side, said coupling device including a downwardly oriented cylindrical member located intermediate said bottom side and said third elongated resilient hose said first side, said downwardly oriented cylindrical member is in communication with the interior of said first elongated resilient hose along its entire length including the area around said nozzle and about said nozzle support, and when said removable nozzle support is removed from said first elongated resilient hose said second side, said nozzle and a first portion of said second hose said second side are exposed, permitting said nozzle to access areas on the workpiece which would not be accessible with said removable nozzle support remaining attached to said first elongated resilient hose said second side, and when said attachment is attached to said spraying device and said spraying device is actuated, said third elongated resilient hose said second side is connected to a vacuum generator which establishes a vacuum in said third elongated resilient hose and an annular region intermediate said first elongated resilient hose and said second resilient hose, and simultaneously said nozzle at said second hose said second side discharges and atomizes said atomizable substance into the hard to access area, which creates overspray and the vacuum causes the overspray to be removed from the hard to access area, by traversing through said annular region intermediate said first elongated resilient hose and said second resilient hose, then passing through said coupling device said first side, and then further passing through said coupling device said bottom side, and then further passing into said third elongated resilient hose whereby the overspray is rendered harmless by a filter and then the remediated air is exhausted to the atmosphere.
