Abstract: An improvement is set forth in a sawing apparatus having a table supporting a workpiece, a fence for guiding the workpiece and an operator moveable electrically operated saw having a first normally biased off switch controlling application of electric power to the apparatus, the switch being positioned to be controlled by the hand of an operator which controls movement of the saw. The improvement comprises a second normally biased off switch connected in series with the first normally biased off switch, the second switch being mounted adjacent to the fence a sufficient distance from the saw blade to prevent the saw blade from contacting the operator's off hand when the off hand is activating the second switch and in a position whereat the off hand can, simultaneously with activating the second switch, adjust the position of the workpiece along the fence. Since in order for the saw blade to rotate both hands of an operator must be holding onto normally off switches and since both switches are in positions removed from the area of movement of the saw blade, the operator is protected from accidently cutting himself. Yet, the apparatus allows the operator adequate control of the workpiece being cut and further allows a radial arm saw to function as a ripping saw without interference.

Abstract: An improvement is set forth in a sawing apparatus having a workpiece support structure and an operator moveable electrically operated saw having a first normally biased off switch controlling application of electric power thereto, the switch being positioned to be controlled by the hand of an operator which controls movement of the saw. The improvement comprises a device adapted for gripping, positioning and clamping a workpiece relative to the workpiece support structure and a second normally biased off switch connected in series with the first normally biased off switch, the second switch being positioned to be controlled by the off hand of the operator while the off hand is utilizing the device. Since both hands of an operator must be holding onto normally off switches and since both switches are in positions removed from the area of movement of the saw blade, the operator is protected from accidently cutting himself. Yet, the device allows the operator adequate control of the workpiece being cut and further allows the radial arm saw to function as a ripping saw without interference.

Abstract: The invention provides a longitudinally extending adhesive tape product adapted to be cut off into a plurality of tape segments by use of a transverse cutting edge. The product comprises a longitudinally extending tape wound into a roll, the tape having a first side which is adhesive free, a plurality of longitudinally separated indicia and a second side which has a corresponding plurality of longitudinally separated and transversely extending coating bands of pressure sensitive adhesive. The coating bands have leading and trailing edges and are separated by portions of the second side of the tape which are substantially adhesive free. The indicia are so located relative to the coating bands whereby when one of the indicia is aligned in a specified relation to the cutting edge and a tape segment is cut off, the cut off tape segment has a single one of the coating bands and the coating band on the cut off tape segment is located adjacent a transverse edge of the tape segment. A method is also set forth of cutting off such tape segments.
