Abstract

An improved table top chain link providing a plurality of upstanding ribs on the top surface thereof in order to allow for cooperative engagement with a transfer comb and the in-line transfer of articles to and from the transfer comb to the conveyor belt.

Claims

1. In a link having a greater width than length and used for constructing an endless single-link wide conveyor belt of the type with an upper and lower run and adapted to traverse one or more curves in the pathway along the upper run thereof, which link defines a female portion in the medial portion of the leading edge thereof and a male portion in the medial portion of the trailing edge thereof so that said male portion of a first link may be received in the female portion of a second trailing link and secured together by a pin extending generally parallel to and between the longitudinal axis of each of said links, said pin allowing both relative vertical pivotal movement and relative horizontal pivotal movement between the first and second links;

the improvement wherein said link comprises a plurality of spaced-apart upstanding rib elements on the top surface thereof, said rib elements extending a distance no greater than the distance from the front to the back of said link and defining a plurality of spaces therebetween to accommodate the spaced-apart parallel teeth of a conveyor transfer comb.

2. A link in accordance with claim 1 wherein said rib elements are integrally formed with said link.

3. A link in accordance with claim 1 wherein said rib elements are substantially perpendicular to the top surface of said link.

4. A link in accordance with claim 3 wherein said rib elements extend lengthwise in a direction substantially perpendicular to the longitudinal axis of said link.

5. A link in accordance with claim 1 wherein said rib elements are dimensioned such that all have substantially the same height and length, said height being less than said length.

6. A link in accordance with claim 1 wherein the outermost rib element on each side of said link extends to a height greater than the height of the rib elements therebetween.

7. A link in accordance with claim 6 wherein the rib elements between said outermost rib elements are dimensioned such that all have substantially the same height and length, said height being less than said length, and said outermost rib elements are dimensioned such that both have substantially the same height and length, said height being greater than said length.

8. A link in accordance with claim 1 wherein at least one roller element adapted to be freely rotatable is rotatably secured to each of a plurality of spaced-apart pairs of said rib elements so that the uppermost surface of each of said roller elements extends above the uppermost surface of said associated pair of rib elements.

9. A link in accordance with claim 8 wherein the outermost rib element on each side of said link extends to a height greater than the height of the rib elements and roller elements therebetween.

10. In a link having a greater width than length and used for constructing an endless single-link wide conveyor belt of the type with an upper and lower run and adapted to traverse one or more curves in the pathway along the upper run thereof, which link defines a female portion in the medial portion of the leading edge thereof and a male portion in the medial portion of the trailing edge thereof so that said male portion of a first link may be received in the female portion of a second trailing link and secured together by a pin extending generally parallel to and between the longitudinal axis of each of said links, said pin allowing both relative vertical pivotal movement and relative horizontal pivotal movement between the first and second links;

the improvement wherein said link comprises a plurality of integral, spaced-apart elongate

rib elements on the top surface thereof, said elongate rib elements extending lengthwise generally perpendicularly to the longitudinal axis of said link a distance no greater than the distance from the front to the back of said link and extending vertically generally perpendicularly to the top surface of said link, said plurality of rib elements defining a plurality of spaces therebetween to accommodate the spaced-apart parallel teeth of a conveyor transfer comb.

11. A link in accordance with claim 10 wherein said rib elements are dimensioned such that all have substantially the same height and length, said height being less than said length.

12. A link in accordance with claim 10 wherein the outermost rib element on each side of said link extends to a height greater than the height of the rib elements therebetween.

13. A link in accordance with claim 12 wherein the rib elements between said outermost rib elements are dimensioned such that all have substantially the same height.

14. A link in accordance with claim 10 wherein at least one roller element adapted to be freely rotatable is rotatably secured to each of a plurality of spaced-apart pairs of said rib elements so that the uppermost surface of each of said roller elements extends above the uppermost surface of said associated pair of rib elements.

15. A link in accordance with claim 14 wherein the outermost rib element on each side of said link extends to a height greater than the height of the rib elements and roller elements therebetween.
