Abstract

A work tool for a machine is provided including a laminated member having a plurality of layers of plates. Each plate is arranged in parallel to the other plates and has a face in contacting relation with an opposing face of an adjacent plate. Adjacent plates are secured together by welds along only a portion of an exterior surface of the laminated member. A plurality of pins hold together the plurality of layers of plates. Each pin is received in a respective opening that extends through each plate in the plurality of layers between opposing first and second surfaces of the laminated member.

First claim

I claim:

1. A work tool for a machine comprising:
a laminated member including a plurality of plates, each plate of the plurality of plates being arranged in parallel and having a face in contacting relation with an opposing face of an adjacent plate; and
a plurality of pins that hold together the plurality of plates, each pin being received in a respective opening that extends through each plate in the plurality of plates between opposing first and second surfaces of the laminated member, wherein the laminated member includes a lower leg having a forward end portion and a rear end portion and an upper leg having an upper end portion and a lower end portion, the lower end portion of the upper leg intersecting with the rear end portion of the lower leg, and wherein at least one pin extends through the upper leg and at least one pin extends through the lower leg.

2. The work tool of claim 1 wherein the lower leg and the upper leg extend perpendicularly relative to each other.

3. The work tool of claim 1 further including a heel portion extending in a rearward direction away from the intersection of the upper leg and the lower leg.

4. The work tool of claim 3 wherein the heel portion has a lower surface that extends in an upward direction as the lower surface extends rearward away from the intersection of the upper leg and the lower leg.

5. The work tool of claim 4 wherein at least one pin extends through the heel.

6. The work tool of claim 5 wherein the lower surface of the heel curves upward as it extends rearward from the intersection of the upper leg and lower leg.

7. The work tool of claim 6 wherein an upper surface of the heel extends upward from the distal end portion to a rear surface of the upper leg.

8. The work tool of claim 7 wherein the plates are held together by a plurality of pins with each pin being received in a respective opening that extends through each plate in the plurality of layers.

9. The work tool claim 8 wherein one of the plurality of pins extends through the lower leg, one of the plurality of pins extends through the upper leg and one of the plurality of pins extends through the heel.

10. The work tool of claim 1 wherein each plate of the plurality of plates is oriented such that an edge of each of the plates together form an upper load receiving area of the lower leg.

11. The work tool of claim 1 wherein the pins are press fit in their respective openings.

12. The work tool of claim 11 wherein the lower surface curves upward to a distal end portion that is substantially coplanar with an upper surface of the lower leg.
