Abstract

A contact wire clamp includes a first clamp body and a second clamp body. The first clamp body and second clamp body each define a contact wire channel and a safety rope channel. The safety rope channel includes a plurality of ridges, each of the plurality of ridges spaced apart from neighboring ridges to define a plurality of troughs. The contact wire clamp further includes a mechanical fastener connecting the first clamp body and the second clamp body together. The safety rope channels of the connected first clamp body and second clamp body face each other and together form a safety rope passage.

First claim

What is claimed is:

1. A contact wire clamp, comprising:
a first clamp body and a second clamp body, the first clamp body and second clamp body each defining a contact wire channel and a safety rope channel, the safety rope channel comprising a plurality of ridges, each of the plurality of ridges spaced apart from neighboring ridges to define a plurality of troughs, wherein the safety rope channel of the first clamp body extends between a first end and a second end, and wherein maximum heights of a ridge of the plurality of ridges most proximate the first end and a ridge of the plurality of ridges most proximate the second end are greater than maximum heights of remaining ridges of the plurality of ridges of the first clamp body, and wherein the safety rope channel of the second clamp body extends between a first end and second end, and wherein maximum heights of a ridge of the plurality of ridges most proximate the first end and a ridge of the plurality of ridges most proximate the second end are greater than maximum heights of remaining ridges of the plurality of ridges of the second clamp body; and
a mechanical fastener connecting the first clamp body and the second clamp body together,
wherein the safety rope channels of the connected first clamp body and second clamp body face each other and together form a safety rope passage.

2. The contact wire clamp of claim 1 , wherein the contact wire channel and the safety rope channel of the first clamp body are parallel to each other, and wherein the contact wire channel and the safety rope channel of the second clamp body are parallel to each other.

3. The contact wire clamp of claim 1 , wherein the ridges of the first clamp body and the second clamp body are arcuate ridges.

4. The contact wire clamp of claim 1 , wherein the troughs of the first clamp body and the second clamp body are arcuate troughs.

5. The contact wire clamp of claim 1 , wherein a maximum diameter of the safety rope passage at any one of the plurality of ridges is between 15% and 45% less than a maximum diameter of the safety rope passage at any one of the plurality of troughs.

6. The contact wire clamp of claim 1 , wherein the mechanical fastener is disposed between a contact wire passage defined by the contact wire channels of the first clamp body and second clamp body and the safety rope passage.

7. The contact wire clamp of claim 1 , wherein the mechanical fastener is a first mechanical fastener, and further comprising a second mechanical fastener, the second mechanical fastener spaced from the first mechanical fastener by the safety rope passage.

8. The contact wire clamp of claim 1 , wherein the first clamp body and the second clamp body are each formed from bronze or a bronze alloy.

9. A contact wire clamp, comprising:
a first clamp body and a second clamp body each extending between a first end and a second end, the first clamp body and second clamp body each defining a contact wire channel and a safety rope channel which extend in parallel to each other, the safety rope channel comprising a plurality of arcuate ridges, each of the plurality of ridges spaced apart from neighboring ridges to define a plurality of arcuate troughs, wherein maximum heights of a ridge of the plurality of ridges most proximate the first end and a ridge of the plurality of ridges most proximate the second end are greater than maximum heights of remaining ridges of the plurality of ridges of the first clamp body, and wherein maximum heights of a ridge of the plurality of ridges most proximate the first end and a ridge of the plurality of ridges most proximate the second end are greater than maximum heights of remaining ridges of the plurality of ridges of the second clamp body; and
a mechanical fastener connecting the first clamp body and the second clamp body together,
wherein the safety rope channels of the connected first clamp body and second clamp body face each other and together form a safety rope passage.

10. The contact wire clamp of claim 9 , wherein a maximum diameter of the safety rope passage at any one of the plurality of ridges is between 15% and 45% less than a maximum diameter of the safety rope passage at any one of the plurality of troughs.

11. The contact wire clamp of claim 9 , wherein the mechanical fastener is disposed between a contact wire passage defined by the contact wire channels of the first clamp body and second clamp body and the safety rope passage.

12. The contact wire clamp of claim 9 , wherein the mechanical fastener is a first mechanical fastener, and further comprising a second mechanical fastener, the second mechanical fastener spaced from the first mechanical fastener by the safety rope passage.

13. The contact wire clamp of claim 9 , wherein the first clamp body and the second clamp body are each formed from bronze or a bronze alloy.

14. A contact wire clamp, comprising:
a first clamp body and a second clamp body, the first clamp body and second clamp body each defining a contact wire channel and a safety rope channel, the safety rope channel comprising a plurality of ridges, each of the plurality of ridges spaced apart from neighboring ridges to define a plurality of troughs, wherein the safety rope channel of the first clamp body and the safety rope channel of the second clamp body each extend between a first end and a second end, and wherein a maximum height of a ridge of the plurality of ridges most proximate at least one of the first end or the second end of at least one on the first clamp body or the second clamp body is greater than maximum heights of remaining ridges of the plurality of ridges of the at least one of the first clamp body or the second clamp body; and
a mechanical fastener connecting the first clamp body and the second clamp body together,
wherein the safety rope channels of the connected first clamp body and second clamp body face each other and together form a safety rope passage.

15. The contact wire clamp of claim 14 , wherein the contact wire channel and the safety rope channel of the first clamp body are parallel to each other, and wherein the contact wire channel and the safety rope channel of the second clamp body are parallel to each other.

16. The contact wire clamp of claim 14 , wherein the ridges of the first clamp body and the second clamp body are arcuate ridges.

17. The contact wire clamp of claim 14 , wherein a maximum diameter of the safety rope passage at any one of the plurality of ridges is between 15% and 45% less than a maximum diameter of the safety rope passage at any one of the plurality of troughs.

18. The contact wire clamp of claim 14 , wherein the mechanical fastener is disposed between a contact wire passage defined by the contact wire channels of the first clamp body and second clamp body and the safety rope passage.
