Abstract

530,625. Sharpening cutlery &c. blades. BROWN, J. R. June 14, 1939, No. 17419. [Class 60] Knives, scissor blades &c. are ground on one side, X Fig. 1, of a flanged or like grinding-wheel mounted on a motor spindle in a casing having a slit K for guiding the blade. The slit may be in a detachable nose portion of the casing having a hardened portion against which the cutting edge rests, and a baffle D, Fig. 3, in front of air exit slots E. The wheel may have a coam grinding portion G and a finishing portion g, and be provided with a fan F for drawing air through holes in the other end of the casing bowl the motor and wheel, the latter having holes H for the passage of cooling air as described in Specification 530,670. In a modification, the guide slit is formed in a part of the casing pivoted so that the inclination of the slit may be varied, being locked after adjustment by means such as a spring pin and a series of holes. In a further modification, the casing is arranged above a vertically arranged motor. Reference has been directed by the Comptroller to Specification 524,832.
