Abstract

A wear pad assembly for a tool includes a wear-resistant pad having a hole for receiving a fastener. A mounting bracket is attached to the wear-resistant pad and includes a pair of coaxial holes extending through an upper flange and a lower flange of the mounting bracket configured to engage with an upper surface and a lower surface of an edge of the tool. A quick-release pin secures the wear pad assembly to the tool edge by passing through the hole in the wear-resistant pad, the pair of coaxial holes in the upper and lower flanges of the mounting bracket, and a hole in the edge of the tool.

First claim

The invention claimed is:

1. A wear pad assembly for a tool comprising an edge provided with one or more holes, the wear pad assembly comprising:
a wear-resistant pad, wherein the wear-resistant pad includes a through hole for receiving a fastener;
a mounting bracket configured for attachment to the wear-resistant pad and the tool edge, the mounting bracket including a pair of coaxial holes extending through an upper portion and a lower portion of the mounting bracket configured for engagement with an upper surface and a lower surface of the tool edge, respectively;
a quick-release pin configured for securing the wear pad assembly and mounting bracket to the tool edge, the quick-release pin configured for passing through the through hole in the wear-resistant pad, through one of the coaxial holes in the lower portion of the mounting bracket, through one of the one or more holes provided in the tool edge, and through one of the coaxial holes in the upper portion of the mounting bracket, and the quick-release pin including a locking mechanism comprising a hole in an upper end of the quick-release in configured for receiving a pin; and
a collar configured to be positioned around one end portion of the quick-release pin to act as a spacer between the quick-release pin and the hole in the upper portion of the mounting bracket.

2. A wear pad assembly according to claim 1 , wherein the mounting bracket is configured for releasable attachment to the wear-resistant pad.

3. A wear pad assembly according to claim 1 , wherein the mounting bracket comprises a generally C-shaped element.

4. A wear pad assembly according to claim 1 , wherein the mounting bracket further comprises an attachment surface for attachment to the wear-resistant pad, the attachment surface comprising one or more shear lugs.

5. A wear pad assembly according to claim 4 , wherein the wear-resistant pad comprises one or more blind holes for receiving the one or more shear lugs of the mounting bracket.

6. A wear pad assembly according to claim 1 , wherein the wear-resistant pad comprises one or more through holes for receiving fasteners for attachment of the wear-resistant pad to the mounting bracket.

7. A wear pad assembly according to claim 6 , wherein the one or more through holes are counterbored.

8. A wear pad assembly according to claim 6 , wherein one or more blind holes for receiving the fasteners and the one or more through holes are coaxial.

9. A wear pad assembly according to claim 1 , wherein the locking mechanism is a linchpin.

10. A machine having a tool comprising an edge provided with one or more holes, and further comprising at least one wear pad assembly secured to the edge via the one or more holes, the wear pad assembly comprising:
a wear-resistant pad, wherein the wear-resistant pad includes a through hole for receiving a fastener;
a mounting bracket configured for attachment to the wear-resistant pad and the tool edge, the mounting bracket including an upper portion configured to engage an upper surface of the tool edge and a lower portion configured to engage a lower surface of the tool edge, and a pair of coaxial holes extending through the upper portion and the lower portion of the mounting bracket;
a quick-release pin configured for securing the wear-resistant pad and mounting bracket to the tool edge, the quick-release pin passing through the through hole in the wear-resistant pad, through a hole in the lower portion of the mounting bracket, through one of the one or more holes provided in the edge of the tool, and through a hole in the upper portion of the mounting bracket, and the quick-release pin including a locking mechanism comprising a hole in an upper end of the quick-release pin configured for receiving a pin, and
a collar positioned around one end portion of the quick-release pin as a spacer between the quick-release pin and the hole in the upper portion of the mounting bracket.

11. A machine according to claim 10 , wherein the tool is a bucket.

12. A machine according to claim 11 , wherein the bucket is a loader bucket.

13. A machine comprising:
a tool comprising an edge provided with one or more holes; and
a wear pad assembly secured to the edge of the tool via the one or more holes, said wear pad assembly comprising:
a wear-resistant pad, wherein the wear-resistant pad includes one or more through holes for receiving fasteners;
a mounting bracket configured for attachment to the wear-resistant pad and the tool edge, the mounting bracket including an upper flange configured to engage an upper surface of the tool edge and a lower flange configured to engage a lower surface of the tool edge, and one or more pairs of coaxial holes extending through the upper flange and the lower flange of the mounting bracket;
a quick-release pin configured for securing the wear-resistant pad and mounting bracket to the tool edge, the quick-release pin passing through one of the one or more through holes in the wear-resistant pad, through a hole in the lower flange of the mounting bracket, through one of the one or more holes provided in the tool edge, and through a hole in the upper flange of the mounting bracket, and the quick-release in including a locking mechanism comprising a hole in an upper end of the quick-release in configured for receiving a pin, and
a collar positioned around one end portion of the quick-release pin as a spacer between the quick-release pin and the hole in the upper flange of the mounting bracket.

14. The machine of claim 13 , wherein the mounting bracket further comprises an attachment surface for attachment to the wear-resistant pad, the attachment surface comprising one or more shear lugs.

15. The machine of claim 14 , wherein the wear-resistant pad comprises one or more blind holes for receiving the one or more shear lugs of the mounting bracket.

16. The machine of claim 13 , wherein the mounting bracket comprises a generally C-shaped element.
