  • Patent number: 5375495
    Abstract: An optical system for projecting an alignment marker on to a workpiece relative to the circular blade of a power saw. The light projection system projects a planar beam of light along a plane defined by one side of the blade to designate the location at which that side of the blade will enter the workpiece. An adjustment mechanism may be included to allow movement of the light projection system so that the planar beam of light can be selectively located parallel to the plane defined by either side of the blade.

  • Patent number: 5285708
    Abstract: A miter saw with an optical system for projecting an optical alignment marker onto a workpiece. The miter saw has a base, a turntable rotatably supported by the base, a fence disposed above the base for supporting the orientation of the workpiece located on the base, a support coupled to the rear portion of the turntable, and a cutting apparatus including a blade for cutting the workpiece. The cutting apparatus is pivotally coupled to the support for positioning the blade from a raised position above the workpiece to an operational position for engagement with the workpiece. The light projection system is attached to the cutting apparatus for projecting an optical alignment marker onto the workpiece so that the location at which the blade engages the workpiece is in a selectably adjustable relationship with respect to the position of the optical alignment marker on the workpiece.
