Abstract

293,785. Lippen, P. von der, and Randall, H. G. July 12, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Tools and V-slot sharpeners.-In a knife sharpener of the kind having grinding members or elements e of steel, stone, or other material arranged in opposite so as to cross at their forward edges, the elements are pivoted at their lower ends d and are pressed towards each other by springs f so that they may swing apart and adjust themselves when a knife is inserted from above. The pivot d is carried in brackets c on a base band the elements e are spaced apart laterally at their upper ends by distance pieces h. The springs press the elements e against limiting stops g and the outer movement is limited by adjustable screws l which may also be used for rendering the the elements rigid when operating on very blunt knives. The elements e may consist of flat or round rods and in the latter case may be grooved and ribbed like a sharpening steel.
