Abstract
219,042. Marks, E. C. R., (Durham Duplex Razor Co.). Feb. 20, 1923. Cutting-edges, shaping; electromagnetic workholders. - Knife blades, which are forged with both longitudinal and transverse tapers, are supported while being ground upon holders 11 secured to the rotating table of a Blanchard grinding- machine. The blade is temporarily distorted so that the upper surface lies in a plane which intersects the medium plane of the blade equidistant from its edge throughout its length. This effect is produced by holding the blade on the holder by a number of electromagnets 12, the cores of which terminate in a recess 13 in the upper face of the holder 11 and are of different angularities. Half of the total number of holders are adapted to hold the unground blades while the other half are adapted to hold blades of which one surface has been ground.
