  • Patent number: 6272960
    Abstract: An improved chop saw may include a base assembly, a blade assembly including a blade having a center and a motor for driving the blade, an arm pivotally attached to the base assembly and carrying the blade assembly, the blade assembly being movable between a lower position for engaging and cutting a workpiece disposed on the base, and an upper position not engaging the workpiece. The chop saw further includes a vise for holding the workpiece in place, the vise including a vise screw, a latch support supporting the vise screw, and a vise jaw disposed at the end of the vise screw. Preferably, the maximum distance between the vise jaw and the latch support is about equal or shorter than the distance between the blade center and the latch support, when the blade assembly is at the lower position. Further the chop saw includes a substantially horizontal handle connected to the blade assembly.

  • Patent number: 6262839
    Abstract: An optical unit for projecting an image including first and second locating lines for substantially eliminating the introduction of visual parallax error. In one preferred form, the optical unit is incorporated into a machine for performing a forming operation on a workpiece and is operative to project an image of a portion of a scale to a position easily read by the user during machine operation. The optical unit includes a prism portion having a first side disposed adjacent the scale, a second side at an angle to the first side for reflecting the image and a third side through which the projected image may be viewed. The first locating line is disposed on the first side and the second locating line is disposed on the third side such that visual alignment eliminates the introduction of visual parallax error associated with reading a scale.
