Abstract

A conveyor flight for a chain comprising at least two spaced apart links, and two side plates that connect the links, with each side plate including two spaced apart extension pins extending from the side plate. The flight comprises a metal support, and the metal support includes two spaced apart cylindrical portions adapted to receive the two spaced apart extension pins. The flight also includes a flexible casing surrounding the metal support.

First claim

What is claimed is:

1. A flight for a link of a chain conveyor, the flight comprising:
a flight core secured to an end of at least one pin, the flight core defining a first side and a second side and further including an opening extending between the first side and the second side; and
an encapsulation at least partially surrounding the flight core, the encapsulation filling the opening in the flight core.

2. The flight of claim 1 , wherein the flight core includes a first end and a second end opposite the first end, the first end facing toward a side surface of the link, wherein the encapsulation covers the flight core except for the first end of the flight core.

3. The flight of claim 1 , wherein the encapsulation surrounds at least a portion of the pin located adjacent the flight core.

4. The flight of claim 1 , wherein the encapsulation dampens sound caused by contact between the chain link assembly and adjacent conveyor components.

5. The flight of claim 1 , wherein the flight core defines a core length, and the encapsulation defines an encapsulation length greater than the core length.

6. The flight of claim 1 , wherein the flight core abuts an end of the pin.

7. A flight for a link of a chain conveyor, the link including at least one side surface and at least one flight pin, the flight comprising:
a flight core having a first end and a second end opposite the first end, the first end including at least one surface abutting an end of the flight pin, the flight core spaced apart from the side surface of the link by a gap; and
a sound dampening coating at least partially encapsulating the flight core.

8. The flight of claim 7 , wherein the flight core includes a first side, a second side, and an opening extending between the first side and the second side, and wherein material of the coating fills the opening.

9. The flight of claim 7 , wherein the coating surrounds at least a portion of the flight pin adjacent the flight core.

10. The flight of claim 7 , wherein the first end of the flight core faces toward the side surface, wherein the coating covers the flight core except for the first end of the flight core.

11. The flight of claim 7 , wherein the first end of the flight core faces toward the side surface, wherein the coating covers the first end of the flight core.

12. The flight of claim 7 , wherein the second end of the flight core defines a trapezoidal shape.

13. The flight of claim 7 , wherein the flight core defines a core length, and the coating defines a coating length greater than the core length.

14. The flight of claim 7 , wherein the flight core is removably connected to the flight pin by at least one fastener.

15. A flight for a link of a chain conveyor, the flight comprising:
a flight core configured to be secured to a first end of a flight pin, the flight core configured to be separated from a side surface of the link by a gap, the flight core including a first side, a second side opposite the first side, and an opening extending between the first side and the second side; and
an encapsulation at least partially surrounding the flight core, the encapsulation filling the opening in the flight core.

16. The flight of claim 15 , wherein the flight core includes a first end and a second end opposite the first end, the first end facing toward the side surface, wherein the encapsulation covers the flight core except for the first end of the flight core.

17. The flight of claim 15 , wherein the flight core has a first end and a second end, the second end of the flight core defining a trapezoidal shape.

18. The flight of claim 15 , wherein the flight core defines a core length, and wherein the encapsulation defines an encapsulation length greater than the core length.

19. The flight of claim 15 , wherein the flight core is removably connected to the flight pin by at least one fastener.
