Definitions

  • the D D represent two parallel plates connected by the pin cl, which inclose the handles and jaws at their fulcrums.
  • the lever-handles A A are pivoted between the two plates D D by the pin 0 and are connected with the jaws by the pairs of connecting links or plates E E, which are pivoted to the handles and to the shanks of thejaws.
  • the jaws are pivoted between the plates D D by the pin b, which passes through the plates and jaws.
  • the jaw B is a thin curved cutting-blade, the line of the cutting-edge being convex in shape and terminating at its outer end in a sharp point, as shown in the drawing.
  • the inner or gripping edge of the jaw O is concave in shape, and the gripping-face F is slightly beveled, the bevel falling away from the cutting-surface.

'is strengthened and the cutting-power increased, my invention consisting in the combination of parts and details of construction hereinafter described.
In the accompanying drawing, the figure is a perspective view of the implement.
Similar letters refer to similar parts.
D D represent two parallel plates connected by the pin cl, which inclose the handles and jaws at their fulcrums. The lever-handles A A are pivoted between the two plates D D by the pin 0 and are connected with the jaws by the pairs of connecting links or plates E E, which are pivoted to the handles and to the shanks of thejaws. The jaws are pivoted between the plates D D by the pin b, which passes through the plates and jaws. The jaw B is a thin curved cutting-blade, the line of the cutting-edge being convex in shape and terminating at its outer end in a sharp point, as shown in the drawing. The inner or gripping edge of the jaw O is concave in shape, and the gripping-face F is slightly beveled, the bevel falling away from the cutting-surface.
What I claim, and desire to secure by Letters Patent, is
The combination of the plates D D, connected by the pin (1, the handles A A, pivoted between said plates D D, the connecting-links E E, pivoted to the handles and to the shanks of the jaws, and the cutting-jaw B and beveled gripping-j aw C, pivoted together between said plates D D, as and for the purposes specified.
In testimony whereof I affix my signature in presence of two witnesses.
