Abstract
201,779. Reichmann, W., and Polo Apparatebau Ges. Aug. 17, 1922. Stropping-apparatus ; tools.-A device for grinding and stropping double-edged safety razor blades comprises a frame 1 in which are mounted two spindles 4, one having thereon a crank adapted to be rotated in one direction only, and to rotate the other through gears 7, 8. On the spindles are mounted leather-covered rollers 5, each having a flat portion, and between the rollers is journaled in the frame a blade-holder 9 comprising a lower part with pins 19 thereon to engage the holes in the blade, and an upper part pressed onto the blade by a screw 18. The blade is turned through 180‹, to present the other sides of the edges to the rollers, at every rotation of the rollers, by a finger on a wheel 12 and a maltese-cross wheel 11 which, through gearing 10, 10' rotates the blade-holder; the wheel 12 is secured to the crank spindle. The grinding is effected by stones 22 carried one in an oblique groove 21 in each of the rollers and pressed outwardly by springs 25. The stones are retained in place, and are adjustable by bolts 27 which screw into plates 22<1> secured to the stones and pass through plates 20 on the flat faces of the rollers. The stones may be retracted, to withdraw them below the surfaces of the rollers, by rotation of levers 31, mounted on the bolts 27, to engage projections 35. In operation, the blade is first ground, with the grinding-stones projecting beyond the surfaces of the rollers. The stones are then moved below the surfaces of the rollers, and the sharpening is completed by the leather surfaces.
