Abstract

Disclosed is roller assembly comprising: a base; a shaft mounted on the base, the shaft defining an axis; a pedestal comprising a first arm and a second arm, the first arm and the second arm positioned on the shaft, the pedestal movable axially relative to the shaft; and a roller rotatably positioned on the shaft between the first arm and the second arm of the pedestal, the roller movable axially relative to the shaft.

First claim

That which is claimed is:

1. A roller assembly comprising:
a base;
a shaft mounted on the base, the shaft defining an axis, the shaft vertically fixed relative to the base;
a pedestal comprising a first arm and a second arm, the first arm and the second arm positioned on the shaft, the pedestal movable axially relative to the shaft; and
a roller rotatably positioned on the shaft between the first arm and the second arm of the pedestal, the roller movable axially relative to the shaft; and
wherein the pedestal further comprises a bottom panel extending between the first arm and the second arm, the bottom panel attached to the first arm at a first end of the bottom panel, the bottom panel attached to the second arm at a second end of the bottom panel, the first end disposed opposite from the second end, and wherein the roller is positioned above the bottom panel of the pedestal.

2. The roller assembly of claim 1 , wherein the shaft is axially fixed relative to the base.

3. The roller assembly of claim 1 , wherein the pedestal is rotationally fixed about the axis.

4. The roller assembly of claim 1 , wherein the shaft is supported by a first lug and a second lug of the base, and wherein the pedestal is positioned between the first lug and the second lug.

5. The roller assembly of claim 1 , wherein the roller is positioned above the base.

6. A roller assembly comprising:
a base defining a base surface, the base comprising a first lug and a second lug positioned on the base surface, the base surface extending from the first lug to the second lug;
a shaft supported by the first lug and the second lug of the base, the shaft defining an axis;
a pedestal positioned on the shaft between the first lug and the second lug, the pedestal axially movable relative to the shaft, a bottom panel of the pedestal axially movably positioned on the base surface relative to the axis; and
a roller rotatably positioned on the shaft, the roller axially movable between the first lug and the second lug, the roller positioned above the base.

7. The roller assembly of claim 6 , wherein the first lug and the second lug extend vertically upward substantially perpendicular to the base surface.

8. The roller assembly of claim 6 , wherein the roller is a first roller, and wherein the roller assembly further comprises a second roller positioned on the shaft between the first lug and the second lug.

9. The roller assembly of claim 8 , further comprising a spacer disposed between the first roller and the second roller.

10. The roller assembly of claim 6 , wherein the first lug defines a roller shaft opening, and wherein the shaft extends through the roller shaft opening.

11. The roller assembly of claim 6 , further comprising a first pin and a second pin extending through the shaft, the first pin and the second pin disposed outside of the first lug and the second lug, the first pin and the second pin retaining the shaft on the base.

12. The roller assembly of claim 6 , wherein the roller is positioned on a bearing configured to rotate.

13. A roller assembly comprising:
a base comprising a first lug and a second lug;
a shaft mounted on the base, the shaft defining an axis, the shaft supported by the first lug and the second lug;
a pedestal positioned on the shaft between the first lug and the second lug, the pedestal movable axially relative to the shaft;
a slide bearing comprising a first plate and a second plate, the first plate attached to the base, the second plate attached to the pedestal, the first plate configured to slide relative to the second plate; and
a roller rotatably positioned on the shaft, the roller movable axially relative to the shaft.

14. The roller assembly of claim 13 , wherein at least a one of the first plate and the second plate comprises polytetrafluorethylene (PTFE).

15. The roller assembly of claim 13 , wherein the pedestal comprises a bottom panel movably positioned on the base, and wherein the second plate is attached to the bottom panel.

16. The roller assembly of claim 15 , wherein the roller is positioned above the bottom panel.

17. The roller assembly of claim 13 , wherein the base defines a base surface, and wherein the base surface is substantially parallel to the axis.

18. The roller assembly of claim 13 , wherein the base is rotationally fixed about the axis.

19. The roller assembly of claim 13 , wherein the first lug and the second lug are each rigidly fixed to the base.
