Abstract
417,928. Sharpening knives &c. LAW, E. H., Sandon, Tudor Close, Kingsbury, Middlesex, HENRY, A., 9, Ely Place, Holborn, and ROLLS RAZOR, Ltd., 255, Cricklewood Broadway, Cricklewood, both in London. March 8, 1933, No. 7075. [Class 60.] A machine for grinding or sharpening knives &c. comprises a hollow base 1 in which are journalled, between fixed conical bearing points 5 and adjustable points 6, two parallel spindles 3 ; the bearings 6, 5 are carried respectively by a lug 7 on the base, and a hollow upstanding portion 2<1> of the base. Each spindle carries two axially spaced grinding-wheels 4, the wheels on one spindle being disposed in staggered relationship to those on the other spindle, and the wheels being of such size as to overlap when interengaged. The spindles 3 are driven in opposite directions by worm pinions 11 thereon meshing. with skew gears 12 within the base and carried by a transverse shaft 14 driven by a handle 15. Pins 13 are carried by the base 1 in the spaces between the wheels 4 and serve as a guide for a knife. The spindles 3 each may carry only one wheel 4, or may carry more than two wheels ; the spindles may be driven by an electric motor housed in the base 1. A wooden block 18 serves to prevent contact of the edge of a knife with the lug 7.
