Estimating the term…
A spray gun for applying a liquid spray coating, such as paint, to a surface incorporates a light source system for gauging the position of the spray gun relative to a worksurface in order to optimize application of the coating to the surface. The light source is preferably in the form of a laser which emits a pair of light beams toward the worksurface. The pair of light beams converge toward each other in a direction toward the surface, and the position of the beams on the surface is used by the operator to judge the distance of the spray gun from the surface. An adjustment mechanism is interconnected with one of the light beam sources, so as to adjust the point of convergence of the light beams. A closable door is associated with the spray gun housing at one of the light beam emitting locations, to selectively prevent emission of one of the light beams from the spray gun, such that a single light beam is emitted from the spray gun for use as a reference for spot application of the coating to the surface.
A hand-held spray gun for applying a coating to a surface comprising:
In a spray gun including a housing defining an interior a forward end, a rearward end and a nozzle mounted to the housing forward end for applying a liquid coating to a surface, the improvement comprising a light generating device disposed within the housing and located rearwardly of the housing forward end, and an elongated light-emitting member extending therefrom to a light emission location on the housing for communicating a light beam from the light generating device exteriorly of the housing toward the surface.
