CLAIMS

1. A link assembly for moving material in a direction of movement from a first end of a conveyor toward a second end of the conveyor, the link assembly comprising:

a first link including a first side edge positioned between a first end and a second end of the first link, the first link including a first indicator; and

a second link including a second side edge extending between a first end and a second end of the second link, the second link including a second indicator, the second link coupled to the first link such that the first side edge of the first link overlaps with the second side edge of the second link in a direction transverse to the direction of movement, elongation of the first link in the direction of movement causes the first indicator to move relative to the second indicator, and a position of the first indicator relative to the second indicator providing an indication of a wear condition of the first link.

2. The link assembly of claim 1, wherein the first indicator is a first notch formed into the first side edge of the first link.

3. The link assembly of claim 2, wherein the second indicator is a second notch formed into the second side edge of the second link.

4. The link assembly of claim 1, wherein, when the first indicator is in a predetermined positioned relative to the second indicator, the first link is in condition for replacement.

5. The link assembly of claim 1, wherein the first link includes a plurality of first indicators positioned on the first side edge, and wherein alignment of the second indicator with each one of the plurality of first indicators represents a different wear condition of the first link.

6. The link assembly of claim 1, wherein the second link includes a first protrusion extending away from an outer side surface of the second link, and wherein the first protrusion is configured to engage a drive sprocket for moving the linkage in the direction of movement.

7. The link assembly of claim 6, further comprising a third link coupled to the first link opposite the second link, wherein the third link includes a second protrusion extending away from an outer side surface of the third link, and wherein the second protrusion is configured to engage the drive sprocket.

8. The link assembly of claim 6, wherein the second link includes a flight positioned adjacent an end of the first protrusion, the flight configured to push the material as the linkage moves from the first end of the conveyor toward the second end of the conveyor.

9. The link assembly of claim 1, wherein the second link includes a first side portion and a second side portion, the first side portion including a first protrusion, the second side portion including a second protrusion, the first protrusion and the second protrusion extending laterally away from one another, wherein the first link is positioned between the first side portion and the second side portion.

10. The link assembly of claim 9, wherein the first side portion and the second side portion are integrally formed with one another.

11. The link assembly of claim 1, wherein the second link includes a wear indicator formed in at least one of an upper surface and a lower surface of the second link, and wherein the wear indicator is configured to represent a second wear condition of the one of the upper surface and the lower surface.

12. A linkage for moving material in a direction from a first end of a conveyor toward a second end of the conveyor, the linkage comprising:

a link including a first surface and a second surface opposite the first surface, the second surface configured to slide relative to a support surface of the conveyor as the linkage moves from the first end of the conveyor toward the second end of the conveyor, at least one of the first surface and the second surface including a wear indicator representing a surface wear condition of the at least one of the first surface and second surface.

13. The linkage of claim 12, wherein the wear indicator includes an aperture having an initial predetermined depth in the at least one of the first surface and the second surface, and wherein, when the aperture disappears from the at least one of the first surface and the second surface, the link is in condition for replacement.

14. The linkage of claim 13, wherein the wear indicator includes a plurality of apertures each having an initial predetermined depth in the at least one of the first surface and the second surface, and wherein the wear indicator indicates an extent of surface wear as each of the plurality of apertures disappears from the at least one of the first surface and the second surface.

15. The linkage of claim 12, wherein the wear indicator includes at least one aperture having a first end, a second end, and a recessed surface extending between the first end and the second end, the recessed surface oriented at an oblique angle relative to the associated one of the first surface and the second surface, the at least one aperture incrementally disappears as the associated one of the first surface and the second surface wears.

16. The linkage of claim 15, wherein the at least one aperture includes a plurality of discrete apertures aligned between the first end and the second end.

17. The linkage of claim 12, wherein the link includes a first protrusion extending away from an outer side surface of the link, and wherein the first protrusion is configured to engage a drive sprocket for moving the linkage in the direction of movement.

18. The linkage of claim 17, wherein the link is a first link, and wherein the linkage further comprises

a second link coupled to the first link, and

a third link coupled to the second link opposite the first link, wherein the third link includes a second protrusion extending away from an outer side surface of the third link, and wherein the second protrusion is configured to engage the drive sprocket.

19. The linkage of claim 18, wherein the third link includes a flight positioned adjacent an end of the second protrusion, the flight configured to push the material as the linkage moves from the first end of the conveyor toward the second end of the conveyor.

20. The linkage of claim 12, wherein the link includes a first side portion and a second side portion, the first side portion including a first protrusion, the second side portion including a second protrusion, the first protrusion and the second protrusion extending laterally away from one another, the first side portion and the second portion being integrally formed with one another.

21. The linkage of claim 12, wherein the link includes a first side portion and a second side portion, the first side portion including a first protrusion, the second side portion including a second protrusion, the first protrusion and the second protrusion extending laterally away from one another, the first side portion and the second portion being separate from one another.
