Abstract
A shear assembly is presented for use with different types of motorized vehicles and is generally provided with an upper cutting jaw, a lower receiving jaw having an open pocket, and an insert disposed within the open pocket. The insert is positioned to engage a cutting edge of the upper jaw when the jaw is in a closed position. In some embodiments, the insert is comprised of a material that permits the insert to yield to the cutting edge of the lower jaw when the cutting edge engages the insert.
Claims16
In combination:
- a motorized vehicle;
- and
- a shear, operatively coupled with said motorized vehicle, comprising:
- an upper jaw having forward and rearward end portions, upper and lower side portions, and a cutting edge formed at least partially along said lower side portion;
- a lower jaw having forward and rearward end portions and an upper edge portion;
- said rearward end portion of said lower jaw being operatively pivotably coupled to the rearward end portion of said upper jaw so that said shear may be selectively moved between open and closed positions;
- said lower jaw being comprised of first and second side members that are laterally spaced from one another to define an open pocket in the upper edge portion of said lower jaw that is shaped and sized to receive at least a portion of the cutting edge of said upper jaw when said shear is in said closed position;
- an insert disposed within the open pocket of said lower jaw and positioned to engage the cutting edge of said upper jaw when said shear is in said closed position;
- said insert being comprised of a material that permits said insert to yield to the cutting edge of said upper jaw when the cutting edge engages said insert;
- at least one actuator operatively coupled with said upper jaw to selectively move said shear between said open and closed positions;
- and
- a mounting bracket operatively coupling said shear with said motorized vehicle.
