Abstract
Gripping cutters have either shearing blades or blade-and-anvil cutting members. Attached to one lateral side of each cutting member is a movable jaw arranged to grip the elements being cut when the cutter is closed and to release the elements when open. Each jaw has a pair of elongate parallel pins extending from its rear face. A pair of supports affixed to each lateral side have an aperture for slidably receiving a pin. A compression spring on the pin forces the jaws together and an adjustable stop on the pin limits the extent of the jaw movement so that the relative position of the blades at the moment of release of the cut elements may be adjusted. Resilient jaw faces may be provided for gripping small and large branches simultaneously.
Claims8
A gripping cutter for cutting and holding elongate elements, said cutter comprising:
- A) first and second cutting members movably connected together, each member having two opposed lateral surfaces;
- B) a first operating element operatively connected to said first member;
- C) a second operating element operatively connected to said second member;
- D) said operating elements arranged for moving said members toward one another for cutting and gripping in a closed position and for moving said members away from one another for releasing said elements in an open position;
- E) a pair of movable jaws, each jaw having a gripping face and a rear face;
- F) a pair of elongate parallel, spaced apart, pins attached to, and extending from, the rear face of each jaw;
- G) a pair of supports each attached to a respective lateral surface of each member such that said supports are on a common side of said cutter, each support having a leg upstanding from said lateral surface, with each leg having an aperture therethrough, with each aperture arranged to slidably receive one of said pins;
- H) spring bias means between each said jaw and each said support for forcing said jaws toward one another such that said gripping faces are springably pressed together when said cutting members are in said closed position for gripping cut elements;
- and
- I) a stop element mounted on each said pin for limiting axial movement of said pin relative to said leg for regulating the distance between said gripping faces when said cutter is in open position for releasing cut elements.
