  • Scaling needle gun shroud
    Patent number: 5267382
    Abstract: A needle scaling device for environmentally safe removal of material such as lead paint or the like, from difficult to clean surfaces, such as bridges. The needle scaling device includes a plurality of reciprocably movable needles which strike the surface being treated, to chip away the paint. A cowling is disposed about the distal end of the device to enshroud the needles. The cowling has an annular array of bristles disposed on its distal end, to provide a flexible shroud and hence a containment plenum around the needles.
