Abstract

1389215 Grinding T WALLER and F W SCHWYN 30 May 1972 [27 May 1971] 17493/71 Heading B3D A blade sharpening device comprises a grinding wheel 1, and blade guide means 2 having first and second guide surfaces 3, 4 arranged V- wise and spaced from the wheel, the proximate edges of the surfaces being in alignment with a chord of the wheel, and third and fourth guide surfaces 3a, 4a co-operating with the second and first surfaces, respectively, for guiding a blade in contact with the wheel. The wheel is mounted on a vertical spindle 8a driven by a motor 8 supported in a frusto-pyramid housing 12 which may be of metal or plastics material, such as polypropylene, reinforced with glass fibre. The guide means 2 is adjustably supported by screws 21 on the housing and the first and second guide surfaces 3, 4 are each at an angle of approximately 40 degrees to the surface of the wheel. The lower edges 5, 6 of the surface define a slot 7 for a knife blade or scissor blade, guided by one of the surfaces. Each surface is undercut to form the guide surfaces 3a, 4a which are parallel to the surfaces 4, 3, respectively. The surfaces are of plastics material, such as polypropylene. As the grinding wheel means, the guide means is lowered by adjustment of the screws 21.
