Abstract
1444366 Punching devices A HYDE W J HEGINBOTHAM and T BARLOW 17 Jan 1974 [24 Jan 1973] 3622/73 Heading B4B A paper-punch device comprises a punch 19 having a cutting edge at one end, the cutting edge including a pair of diametrically opposed cutting surfaces 29 one of which is longer than the other. As shown in Fig. 3, a pair of punches are each mounted in square-section bores 15, each punch having a square plate 27 for engagement with the bore to prevent rotation of the punch. The punches and an operating handle 13 are returned after a punching stroke by means of springs 28. The cutting-edge of the punch may be formed with a V-shaped cross-section or of cylindrical concave form, the centre of which is offset to one side of the axis of the punch. The waste paper discs may be removed from the base 11 of the tool after a plastics plate 22 has been unscrewed. An adjustable paper guide 26 is provided. In a modification, the device may be power-actuated.
