A side view of the nippers is represented in the drawing with all the parts in their relative position. A lis the lower or single side of said shears. B and G are the two levers on the opposite side. At D in A and E in B` will be seen the cutting-edges. The shears have connections like those represented at F, G, and H on both sides of the levers A and O. The levers C and A are connected by the piece F, and the levers B and G are joined by the two connections G and H through the center of pulley I. It will be noticed that one side ofthe pulley` I rests in a curve in the end of'the lever B, whose radius equals the radius 4ot the pulley I. It will be obvious that this The pulley I and the connections G and H, l
in combination with levers C and B, as set forth.
