Abstract

22,300. Reinfrank, J. Oct. 10. Cutting-edges, treating. - A grinding-machine for sharpening curved knives, such as are used by furriers, is constructed with two grinding-disks 18, 19 adjustable towards each other on a verticallyadjustable frame 9. Beneath the disks is a segment 20 pivotally mounted on an axle 21 and adapted to hold the curved knife 23; the segment is rocked about its axle by a rack and pinion 27 and traverses the knife between the grinders. The segment operated by a rack and pinion may be used with an ordinary grindstone.
