Abstract

A power line cutter is described. The power line cutter may be used in emergency or repair situations to cut down or broken power lines. The power line cutter is provided with a long extension handle such that the operator may use the power line cutter to cut power lines hanging or suspended above the operator.

The power line cutter includes a first blade having a first blade cutting surface and a first blade lever. The power line cutter further includes a second blade having a second blade cutting surface and a second blade lever. A first handle is pivotally engaged to the first blade, and the first handle includes a first pulley. A second handle is pivotally engaged to the second blade, and the second handle includes a second pulley. The first handle is pivotally engaged to the second handle. A blade support is pivotally engaged to the first blade and to the second blade to pivotally position the first blade cutting surface opposite of the second blade cutting surface. A line passes from the first handle to the second pulley. The line further passes to the first pulley. A bracket extends from the blade support and the bracket connects or attaches to an extension.

4. The power line cutter according to claim 1, further comprising a first spring and a second spring engaged to the first blade lever and to the second blade lever to urge the first blade lever and the second blade lever toward each other.

5. The power line cutter according to claim 1, wherein the first handle is pivotally engaged to the second handle at a pivot, and the first handle and the second handle pivot toward one another.

6. The power line cutter according to claim 1, wherein the blade support is pivotally engaged to the first blade at a first blade fulcrum and the blade support is pivotally engaged to the second blade at a second blade fulcrum.

7. The power line cutter according to claim 1, wherein pulling on the line causes the first and second handles to move towards each other.

8. The power line cutter according to claim 1, wherein the bracket is attached or integral to a bottom surface of the blade support, wherein the bracket has a curved shape.

9. The power line cutter according to claim 1, wherein the blade support includes a top surface and the top surface is immediately adjacent to an opening between the first blade cutting surface and the second blade cutting surface.

10. The power line cutter according to claim 1, wherein a first rod is attached to or integral with the first blade lever and a second rod is attached to or integral with the second blade lever, and a first spring connects the first rod and the second rod, and a second spring connects the first rod and the second rod.

11. The power line cutter according to claim 1, wherein the first handle includes an opening adjacent to the first pulley.

12. The power line cutter according to claim 1, wherein the first blade cutting surface and the second blade cutting surface are on an opposite side of the first blade support from springs connecting the first blade lever and the second blade lever.

13. The power line cutter according to claim 1, wherein the line passes between the first pulley and the second pulley in a generally perpendicular arrangement to an extension connected to the blade support.

14. The power line cutter according to claim 1, wherein the first blade cutting surface and the second blade cutting surface open opposite of an extension connected to the blade support.

15. The power line cutter according to claim 1, wherein the first blade cutting surface and the second blade cutting surface cut from a bottom surface of a power line.

16. The power line cutter according to claim 1, wherein the first blade cutting surface and the second blade cutting surface provide a v-shaped opening that is raised toward the power line.

17. The power line cutter according to claim 1, wherein pulling on the line causes the first handle and the second handle to compress, wherein the first handle actuates the first blade lever and the second handle actuates the second blade lever to pivot the first blade at the first blade fulcrum and the second blade at the second blade fulcrum resulting in the first blade cutting surface and the second blade cutting surface compressing together.

18. A power line cutter, comprising:

a first blade comprising a first blade cutting surface;

a second blade comprising a second blade cutting surface;

the first blade cutting surface and the second blade cutting surface forming an opening;

a first handle pivotally engaged to the first blade, the first handle comprising a first pulley;

a second handle pivotally engaged to the second blade, the second handle comprising a second pulley;

the first handle pivotally engaged to the second handle;

a blade support pivotally engaged to the first blade and to the second blade to pivotally position the first blade cutting surface opposite the second blade cutting surface;

a line passing between the first and second pulleys;

a bracket extending from the blade support; and

an end of an elongated extension connected or attached to the bracket, wherein the end of the elongated extension is adjacent the opening between the first blade cutting surface and the second blade cutting surface.

19. A power line cutter, comprising:

a first blade comprising a first blade cutting surface and a first blade lever;

a second blade comprising a second blade cutting surface and a second blade lever;

a first handle pivotally engaged to the first blade, the first handle comprising a first pulley;

a second handle pivotally engaged to the second blade, the second handle comprising a second pulley;

the first handle pivotally engaged to the second handle, wherein the first handle and the second handle are configured to both move toward each other;

a blade support pivotally engaged to the first blade and to the second blade to pivotally position the first blade cutting surface opposite the second blade cutting surface;

a line passing from the first handle to the second pulley, the line further passing to the first pulley and putting on the line moves both the handles toward each other; and

an extension connected to or integral with the blade support.

20. A power line cutter, comprising:

a first blade comprising a first blade cutting surface and a first blade lever;

a second blade comprising a second blade cutting surface and a second blade lever;
