Abstract

114,120. Cameron, H., and Cameron, Ltd., J. Oct. 31, 1917. Shear-blades for cutting notches or holes in metal plates are provided with a continuously and uniformly inclined edge. Figs. 1 and 3 show respectively a front and side elevation of a tool for cutting rectangular notches in the edge of a plate, and Fig. 7 shows a development of the three cutting blades, e, f, g showing the continuous cutting edge, e<1>, g<1>, f<1> The plate c to be cut is pressed up to a stop b on the die and the cutter-head d is then depressed. A tool for cutting a rectangular hole is provided with four blades. In the case of a cutter for oval or like holes, as shown in Fig. 16 for instance, each half of the cutting edge forms a continuous incline from one end e to the other e<1>.
