Abstract

911,561. Sanding; sawing. SINGERMANUFACTURING CO. Feb. 10, 1961 [Feb. 24, 1960], No. 5019/61. Classes 60 and 145. [Also in Group XXII] A portable electric tool 12, Fig. 3, such as a belt sander or a sabre saw, is provided with a speed-setting indicator which comprises a knob 15, secured to the spindle of a potentiometer resistance 11. A rotatable setting disc 18, Fig. 2, is provided under the knob and carries markings indicating material to be cut or worked and the coarseness of the sanding belt or saw teeth. The disc 18 is first set with the appropriate material marking against an index mark 28 on the tool housing and the knob 15 is then turned to bring an index mark 31 thereon against the appropriate coarseness marking on the disc.
