Abstract

Official abstract text for this publication.

The present disclosure provides an auto-rack bridge plate locking assembly including a support bracket, a support block, a guide tube, a slidable locking pin partially positioned in the guide tube, a handle removably attachable to the locking pin by a removable roll pin, a fixed pivot pin partially positioned in the guide tube, and a spring positioned in the guide tube between the pivot pin and the locking pin. The present disclosure also provides an auto-rack railroad car bridge plate including a plate configured to extend from one auto-rack railroad car to an adjacent auto-rack railroad car, and such locking assembly connected to the plate and configured to pivotally attach the plate to one of the auto-rack rail road cars.

First claim

Opening claim text (preview).

The invention is claimed as follows: 1. An auto-rack railroad car bridge plate locking assembly comprising: (a) a support bracket defining a pin removal opening; (b) a guide tube connected to the support bracket, the guide tube defining a first roll pin opening and a second roll pin opening; (c) a slidable locking pin partially positioned in the guide tube, the slidable locking pin defining aligned openings and a handle receiving opening; (d) a handle removably attached to the locking pin by a removable roll pin, the handle defining a roll pin opening; (e) a pivot pin partially positioned in and connected to the guide tube; and (f) a spring positioned in the guide tube between the pivot pin and the locking pin, said spring configured to apply a biasing force against the locking pin to push the locking pin in an outward direction from the guide tube. 2. The auto-rack railroad car bridge plate locking assembly of claim 1 , wherein: (i) the support bracket includes a first section, a second section, a third section, a fourth section, and a fifth section, the second section defining the pin removal opening that enables the roll pin to be removed from the locking pin and the handle; (ii) the guide tube defines a central cylindrical lumen, cylindrical openings at opposite ends, the first roll pin opening being cylindrical, the second roll pin opening being cylindrical, and an elongated handle opening; (iii) the slidable locking pin defines the aligned roll pin openings being cylindrical and the handle receiving opening being cylindrical; (iv) the handle includes an attachment section and a gripping section, the attachment section defining the roll pin opening being cylindrical; and (v) the pivot pin includes a body having a first cylindrical section, an intermediate cylindrical section, and a second cylindrical section. 3. The auto-rack railroad car bridge plate locking assembly of claim 2 , wherein the guide tube is cylindrical, the slidable locking pin is cylindrical, the pivot pin is cylindrical, and the spring is cylindrical. 4. The auto-rack railroad car bridge plate locking assembly of claim 2 , which includes a support block positioned between the support bracket and the guide tube. 5. The auto-rack railroad car bridge plate locking assembly of claim 4 , wherein said support block is connected to the support bracket and to the guide tube. 6. The auto-rack railroad car bridge plate locking assembly of claim 5 , wherein the support block is welded to the support bracket and to the guide tube. 7. The auto-rack railroad car bridge plate locking assembly of claim 4 , wherein the support block is positioned between the third section of the support bracket and the guide tube. 8. The auto-rack railroad car bridge plate locking assembly of claim 1 , which includes a support block positioned between the support bracket and the guide tube. 9. The auto-rack railroad car bridge plate locking assembly of claim 8 , wherein the support block is connected to the support bracket and to the guide tube. 10. The auto-rack railroad car bridge plate locking assembly of claim 9 , wherein the support block is welded to the support bracket and to the guide tube. 11. The auto-rack railroad car bridge plate locking assembly of claim 1 , wherein the support bracket includes a first section, a second section, a third section, a fourth section, and a fifth section, the second section defining the pin removal opening that enables the roll pin to be removed from the locking pin and the handle. 12. The auto-rack railroad car bridge plate locking assembly of claim 1 , wherein: (a) the guide tube defines a central cylindrical lumen, cylindrical openings at opposite ends, the first roll pin opening being cylindrical, the second roll pin opening being cylindrical, and an elongated handle opening; and (b) the slidable locking pin defines the aligned roll pin openings being cylindrical and the handle receiving opening being cylindrical. 13. The auto-rack railroad car bridge plate locking assembly of claim 1 , wherein the handle includes an attachment section and a gripping section, and wherein the attachment section defines the roll pin opening being cylindrical. 14. The auto-rack railroad car bridge plate locking assembly of claim 1 , wherein the pivot pin includes a body having a first cylindrical section, an intermediate cylindrical section, and a second cylindrical section. 15. The auto-rack railroad car bridge plate locking assembly of claim 1 , wherein the support bracket, the guide tube, the locking pin, the handle, the roll pin, the pivot pin, and the spring are all made of steel. 16. An auto-rack railroad car bridge plate comprising: a plate configured to extend from one auto-rack railroad car to an adjacent auto-rack railroad car; and a locking assembly connected to the plate and configured to pivotally attach the plate to one of the auto-rack rail road cars, said locking assembly including: (a) a support bracket defining a pin removal opening; (b) a guide tube connected to the support bracket, the guide tube defining a first roll pin opening and a second roll pin opening; (c) a slidable locking pin partially positioned in the guide tube, the slidable locking pin defining aligned openings and a handle receiving opening; (d) a handle removably attached to the locking pin by a removable roll pin, the handle defining a roll pin opening; (e) a pivot pin partially positioned in and connected to the guide tube; and (f) a spring positioned in the guide tube between the pivot pin and the locking pin, said spring configured to apply a biasing force against the locking pin to push the locking pin in an outward direction from the guide tube. 17. The auto-rack railroad car bridge plate of claim 16 , wherein: (i) the support bracket includes a first section, a second section, a third section, a fourth section, and a fifth section, the second section defining the pin removal opening that enables the roll pin to be removed from the locking pin and the handle; (ii) the guide tube defines a central cylindrical lumen, cylindrical openings at opposite ends, the first roll pin opening being cylindrical, the second roll pin opening being cylindrical, and an elongated handle opening; (iii) the slidable locking pin defining the aligned roll pin openings being cylindrical and the handle receiving opening being cylindrical; (iv) the handle includes an attachment section and a gripping section, the attachment section defining the roll pin opening being cylindrical; and (v) the pivot pin includes a body having a first cylindrical section, an intermediate cylindrical section, and a second cylindrical section. 18. The auto-rack railroad car bridge plate of claim 17 , wherein the guide tube is cylindrical, the slidable locking pin is cylindrical, the pivot pin is cylindrical, and the spring is cylindrical. 19. The auto-rack railroad car bridge plate of claim 17 , which includes a support block positioned between the support bracket and the guide tube. 20. The auto-rack railroad car bridge plate of claim 19 , wherein said support block is connected to the support bracket and to the guide tube. 21. The auto-rack railroad car bridge plate of claim 20 , wherein the support block is welded to the support bracket and to the guide tube. 22.
