Abstract

An unload elbow with spherical wear pocket is disclosed which comprises a body having an inlet end, an outlet end, and a spherical wear pocket formed near the outlet end. The spherical wear pocket is capable of trapping material that is being unloaded through the unload elbow to trap a portion of material being unloaded so that any other material being unloaded will contact the trapped material and not impact the wear pocket to prematurely wear out the unload elbow.

Claims

1. An unload elbow with spherical wear pocket comprising:

a body having an inlet end, an outlet end, a passage between the inlet end and the outlet end, and a spherical wear pocket formed near the outlet end;

a connector fitting formed around the inlet end; and

a connector fitting formed around the outlet end.

2. The unload elbow with spherical wear pocket of claim 1 wherein the connector fitting formed around the inlet end is a male connector fitting.

3. The unload elbow with spherical wear pocket of claim 1 wherein the connector fitting formed around the inlet end is a female connector fitting.

4. The unload elbow with spherical wear pocket of claim 1 wherein the connector fitting formed around the outlet end is a male connector fitting.

5. The unload elbow with spherical wear pocket of claim 1 wherein the connector fitting formed around the outlet end is a male connector fitting.

6. The unload elbow with spherical wear pocket of claim 1 wherein the connector fitting formed around the inlet end comprises a cam surface.

7. The unload elbow with spherical wear pocket of claim 1 wherein the connector fitting formed around the outlet end comprises a groove and a cam surface.

8. The unload elbow with spherical wear pocket of claim 1 wherein the connector fitting formed around the inlet end comprises a collar having an opening and a lever having a cam that fits through the opening in the collar.

9. An unload elbow with spherical wear pocket comprising:

a body having an inlet end, an outlet end, a passage between the inlet end and the outlet end, and a spherical wear pocket formed near the outlet end;

a quick disconnect fitting formed around the inlet end; and

a quick disconnect fitting formed around the outlet end.

10. The unload elbow with spherical wear pocket of claim 9 wherein the quick disconnect fitting formed around the inlet end is a male connector fitting.

11. The unload elbow with spherical wear pocket of claim 9 wherein the quick disconnect fitting formed around the inlet end is a female connector fitting.

12. The unload elbow with spherical wear pocket of claim 9 wherein the quick disconnect fitting formed around the outlet end is a male connector fitting.

13. The unload elbow with spherical wear pocket of claim 9 wherein the quick disconnect fitting formed around the outlet end is a female connector fitting.

14. The unload elbow with spherical wear pocket of claim 9 wherein the quick disconnect fitting formed around the inlet end comprises a groove and a cam surface.

15. The unload elbow with spherical wear pocket of claim 9 wherein the quick disconnect fitting formed around the outlet end comprises a groove and a cam surface.

16. The unload elbow with spherical wear pocket of claim 9 wherein the quick disconnect fitting formed around the inlet end comprises a collar having an opening and a lever having a cam that fits through the opening in the collar.

17. An unload elbow assembly for forming a 90°

change of direction of material flowing through the unload elbow assembly comprising;

a first unload elbow with spherical wear pocket having a body having an inlet end, an outlet end, a passage between the inlet end and the outlet end, and a spherical wear pocket formed near the outlet end, a connector fitting formed around the inlet end, and a connector fitting formed around the outlet end; and

a second unload elbow with spherical wear pocket having a body having an inlet end, an outlet end, a passage between the inlet end and the outlet end, and a spherical wear pocket formed near the outlet end, a connector fitting formed around the inlet end, and a connector fitting formed around the outlet end with the outlet end of the first unload elbow connected to the inlet end of the second unload elbow.

18. The unload elbow assembly of claim 17 wherein the connector fitting formed around the inlet end of the second unload elbow comprises a groove and a cam surface.

19. The unload elbow assembly of claim 17 wherein the connector fitting formed around the outlet end of the first unload elbow comprises a collar having an opening and a lever having a cam that fits through the opening in the collar.

20. The unload elbow assembly of claim 17 wherein each of the wear pockets is capable of trapping material that is being unloaded through each of the unload elbows to trap a portion of material being unloaded so that any other material being unloaded will contact the trapped material and not impact each of the wear pockets to prematurely wear out each of the unload elbows.
