14,467. Harris, I. Nov. 9. Scissors and shears. -- The invention relates to that class of shears known as straight and bent trimmers, bankers' shears, barbers' shears, &c., in which the bows are shaped so as to fit the hand, and a twist is given to the blade to adapt the edges to work easily in close contact. Each blade is formed in one with its bow from one piece of steel, and the operations are effected by means of dies. The blanks roughly shaped in a pair of dies are forged in a second pair shown in the Figures. Fig. 1 shows the upper die, and Fig. 2 the lower. The dies are cut away in a special manner in order to prevent them from binding together. A skew is given to the bows in order to afford a better hold. Spaces E are left round the shaping portion of the dies to receive superfluous metal. This metal is afterwards removed by punching-dies, and the blades are finished in twisting-dies which shape them for grinding.Cataloged By
