Abstract

660,845. Pencil-sharpeners. KARTRO SOCANON. March 2, 1949, No. 5755/49. Class 146 (iii). A sharpener for pencil-leads comprises a number of planar surfaces e.g. 6a, 7, adapted to serve as a support for the end of the lead being sharpened and to support the conical end formed by the sharpening along at least three converging lines, only one of which reaches the point of convergence 9 and extends therebeyond and consists of a narrow and sharp edged slot 5 in one of the planar surfaces. The pyramidal construction is formed by a strip 6a having turned up edges 6 for joining a second strip 7 not reaching to the point of convergence 9. Alternatively, the pyramidal body may be located in a cylindrical body rotatable by a hand-knob and having a pivoted trap to collect the cuttings.
