Patent ID: 8491061

Claim:
A system for providing a temporary, moveable, water spray within the digging area of an underground mine-like tunnel for reducing and settling dust accumulation resulting from the digging work and in which a wall covering material is provided at the work area comprising an attachment for temporarily mounting a water spray hose on the wall covering for directing water spray within the area, comprising: a generally vertically arranged base plate having an upper end with a hook portion for engaging with the wall covering material and exposed forward face; an elongated arm extending forwardly of the plate, with the arm having an end rotatably connected to the plate for adjusting the angle of the arm around its central axis; the arm having a free end upon which a clamp is mounted for receiving and holding the nozzle end of a spray hose; the arm being connected to the plate by a horizontal threaded shaft threadedly connected within a threaded opening to the plate at one end and connected to the arm at its opposite end with the arm being manually rotatable with the shaft for changing the angularity of the arm relative to the plate and for increasing or decreasing the distance between the arm and the plate and thereby positioning the clamp closer to or further from the plate, whereby water may be sprayed through a hose at a pre-selected direction by adjusting the angularity of the arm and the distance from the plate of the clamp, for wetting and disbursing accumulated dust in the work area.
