Abstract

An auto-rack railroad car including a frame, a plurality of upright posts supported by the frame, a deck, and a plurality of deck connector assemblies connecting the deck to the upright posts, each deck connector assembly including at least one wedge.

First claim

The invention claimed is:

1. An auto-rack railroad car comprising:
a frame;
a plurality of upright posts supported by the frame;
a deck; and
a plurality of deck connector assemblies connecting the deck to the upright posts, each deck connector assembly including:
a wedge connected to one of the upright posts, the wedge including a post engagement surface engaging said upright post and an opposing angled bracket engagement surface facing away from said upright post;
a wedge engagement bracket fixedly connected to the deck and engaging the angled bracket engagement surface of the wedge; and
a post clamping bracket connected to the wedge engagement bracket and engaging said upright post.

2. The auto-rack railroad car of claim 1 , wherein one of the upright posts includes a first flange engaged by the post clamping bracket of one of the deck connector assemblies.

3. The auto-rack railroad car of claim 1 , wherein one of the upright post includes a first flange engaged by the post clamping bracket of one of the deck connector assemblies and a second flange engaged by the post clamping bracket of said deck connector assembly.

4. The auto-rack railroad car of claim 1 , wherein the wedge engagement bracket of one of the plurality of deck connector assemblies defines a first plurality of apertures aligned with a corresponding second plurality of apertures of the post clamping bracket of that deck connector assembly.

5. The auto-rack railroad car of claim 1 , wherein one of the deck connector assemblies includes a first post clamping bracket and a second post clamping bracket.

6. The auto-rack railroad car of claim 1 , wherein one of the post-clamping brackets includes a bracket connection plate, a spacer plate, and a flange engagement plate.

7. The auto-rack railroad car of claim 6 , wherein the spacer plate is substantially triangular.

8. The auto-rack railroad car of claim 7 , wherein the bracket connection plate, the spacer plate, and the flange engagement plate form a multi-direction shaped bracket.

9. The auto-rack railroad car of claim 6 , wherein a first plane defined by a surface of the bracket connection plate is angled with respect to a second plane defined by a surface of the flange engagement plate.

10. The auto-rack railroad car of claim 9 , wherein the first plane is at an angle of from 5 to 45 degrees with respect to the second plane.

11. The auto-rack railroad car of claim 1 , wherein one of the wedges includes an alignment pin extending from the flange engagement surface of the wedge.

12. The auto-rack railroad car of claim 1 , wherein one of the wedges includes at least one alignment pin extending from a surface of the wedge.

13. The auto-rack railroad car of claim 1 , wherein a first plane defined by the bracket engagement surface of one of the wedges is at an angle of from 5 to 45 degrees with respect to a second plane defined by the flange engagement surface of the wedge.

14. The auto-rack railroad car of claim 1 , wherein one of the deck connector assemblies includes two wedges connected to an interior surface of one of the upright posts.

15. The auto-rack railroad car of claim 14 , wherein each of said two wedges is connected to the interior surface of said upright post via an alignment pin extending from the flange engagement surface of the wedge through a wedge attachment aperture of one of a plurality of flanges of said upright post.

16. The auto-rack railroad car of claim 1 , wherein one of the deck connector assemblies includes two wedges connected to an exterior surface of one of the upright posts.

17. The auto-rack railroad car of claim 1 , wherein for one of the plurality of deck connector assemblies, the wedge engagement bracket of that deck connector assembly is connected by fasteners to the post clamping bracket of that deck connector assembly.

18. A method of creating an auto-rack railroad car comprising:
attaching a plurality of upright posts to a railroad car frame;
for a plurality of wedges each including a post engagement surface and an opposing angled bracket engagement surface, attaching the plurality of wedges to the upright posts such that for each wedge, the post engagement surface of the wedge engages the upright post to which the wedge is attached and the opposing angled bracket engagement surface of the wedge faces away from the upright post to which the wedge is attached;
fixedly attaching a plurality of wedge engagement brackets to a deck;
fixedly attaching a plurality of post clamping brackets to the wedge engagement brackets; and
lowering the deck onto the railroad car frame such that the wedges are respectively disposed between the wedge engagement brackets and the post clamping brackets, such that the wedge engagement brackets engage the angled bracket engagement surfaces of the wedges, and such that the post clamping brackets engage the upright posts.

19. The method of claim 18 , further comprising attaching the plurality of wedges to the upright posts such that for each wedge, the post engagement surface of the wedge engages an interior facing surface of the upright post to which said wedge is attached.

20. The method of claim 18 , further comprising attaching the plurality of wedges to the upright posts such that for each wedge, the post engagement surface of the wedge engages an exterior facing surface of the upright post to which said wedge is attached.

21. The method of claim 18 , further comprising attaching the plurality of wedges to the upright posts such that the post engagement surface of each of a first plurality of the wedges engages an exterior facing surface of the upright post to which said wedge is attached and such that the post engagement surface of each of a second plurality of the wedges engages an exterior facing surface of the upright post to which said wedge is attached.

22. The method of claim 18 , further comprising for each of the plurality of wedges, attaching the wedge to the respective upright post via an alignment pin extending from a rear surface of the wedge through an aperture defined by said upright post.

23. An auto-rack railroad car comprising:
a frame;
a plurality of upright posts supported by the frame;
a deck; and
a plurality of deck connector assemblies connecting the deck to the upright posts, each deck connector assembly including:
a wedge engagement bracket connected to the deck;
a post clamping bracket connected to the wedge engagement bracket; and
a wedge connected to one of the upright posts, and

wherein one of the post-clamping brackets includes a bracket connection plate, a substantially triangular spacer plate, and a flange engagement plate.

24. An auto-rack railroad car comprising:
a frame;
a plurality of upright posts supported by the frame;
a deck; and
a plurality of deck connector assemblies connecting the deck to the upright posts, each deck connector assembly including:
a wedge engagement bracket connected to the deck;
a post clamping bracket connected to the wedge engagement bracket; and
a wedge connected to one of the upright posts, and

wherein one of the post-clamping brackets includes a bracket connection plate, a spacer plate, and a flange engagement plate, wherein a first plane defined by a surface of the bracket connection plate is angled with respect to a second plane defined by a surface of the flange engagement plate.

25. An auto-rack railroad car comprising:
a frame;
