Abstract

581,877. Pencil-sharpeners. MUNN, R. B. S. July 14, 1944, No. 13539. [Class 146 (iii)] A pencil-sharpener is formed of two parts 1, 7 adapted to be connected by being slid together, and to grip a cutting blade between them so that the blade is enclosed within the sharpener, recesses being formed in the parts to fit a pencil and to present it to the blade edge, and to receive the chips. As shown, two cylindrical recesses 12 are formed in the part 1 to fit the pencils, and are extended by complementary semi-cylindrical grooves 14 in both parts 1, 7 to receive the chips. The holes in the blade, which preferably is of the safety-razor two edged type, fit over pins 4 on the part 1, and the part 7 has a longitudinal groove 10 to allow it to slide into position. Inwardly-projecting flanges 6 on the side walls of the part 1 engage recesses 9 in the part 7, and these flanges are deeper at the centre of their length to force the part 7 against the part 1 and so grip the blade. A convex surface 3 on the part 1 co-operates with a similar concave surface 8 on the part 7 to curve the blade. The parts 1, 7 are made from plastic material or metal. The recesses 12 may be of different diameters for dealing with pencils of differing sizes.
