Official abstract text for this publication.
In various embodiments, the present disclosure provides an door locking assembly splice including an extension tube having opposing top and bottom ends, a lock rod connection assembly connected to the top end of the extension tube, a handle connection assembly connected to the extension tube between the top end and the bottom end of the extension tube, and a cam assembly connected to the bottom end of the extension tube, that enables a damaged door rod locking assembly to be easily, quickly, and efficiently repaired.
Opening claim text (preview).
The invention is claimed as follows: 1. An auto-rack railroad car door locking assembly splice connectable to a portion of a lock rod having an inner surface defining an inner passage, the splice comprising: (a) an extension tube having opposing top and bottom ends; (b) a lock rod connection assembly connected to the top end of the extension tube and partially insertable into the inner passage through a bottom end of the portion of the lock rod, the lock rod connection assembly including a cylindrical lock rod connection tube defining aligned spaced apart fastener openings configured to enable a fastener to be inserted through the fastener openings to connect the cylindrical lock rod connection tube to the portion of the lock rod; and (c) a cam assembly connected to the bottom end of the extension tube. 2. The auto-rack railroad car door locking assembly splice of claim 1 , wherein the extension tube includes a cylindrical elongated wall having an inner surface defining an inner diameter of the extension tube, an outer surface defining an outer diameter of the extension tube, a top end having an upper edge, and a bottom end having a lower edge. 3. The auto-rack railroad car door locking assembly splice of claim 1 , wherein the cylindrical lock rod connection tube includes a cylindrical elongated wall having an outer surface defining an outer diameter of the cylindrical lock rod connection tube, a top end having an upper edge, and a bottom end having a lower edge. 4. The auto-rack railroad car door locking assembly splice of claim 3 , wherein the outer diameter of the cylindrical lock rod connection tube is smaller than the inner diameter of the extension tube such that bottom end of the lock rod connection tube fits into the top end of the extension tube. 5. The auto-rack railroad car door locking assembly splice of claim 1 , which includes a handle connection assembly connected to the extension tube between the top end and the bottom end of the extension tube. 6. The auto-rack railroad car door locking assembly splice of claim 5 , wherein the handle connection assembly includes two spaced apart side walls and an upside down U shaped connection wall. 7. The auto-rack railroad car door locking assembly splice of claim 1 , wherein the cam assembly includes a lower cam structure including a tubular central body, a lower locking tongue connected to and transversely extending from one side of the tubular central body, and a rear lug connected to and transversely extending from an opposite side of the tubular central body. 8. An auto-rack railroad car door locking assembly splice comprising: (a) an extension tube having opposing top and bottom ends, the extension tube including an elongated wall having an inner surface defining an inner diameter of the extension tube, an outer surface defining an outer diameter of the extension tube, the top end having an upper edge, and the bottom end having a lower edge; (b) a lock rod connection assembly connected to the top end of the extension tube, a top end of the lock rod connection assembly configured to be directly connected to a bottom end of a remaining portion of a lock rod; (c) a cam assembly connected to the bottom end of the extension tube; and (d) a handle connection assembly connected to the extension tube between the top end and the bottom end of the extension tube. 9. The auto-rack railroad car door locking assembly splice of claim 8 , wherein the lock rod connection assembly includes a cylindrical lock rod connection tube including a cylindrical elongated wall having an outer surface defining an outer diameter of the cylindrical lock rod connection tube, a top end having an upper edge, and a bottom end having a lower edge. 10. The auto-rack railroad car door locking assembly splice of claim 9 , wherein the outer diameter of the cylindrical lock rod connection tube is smaller than the inner diameter of the extension tube such that bottom end of the lock rod connection tube fits into the top end of the extension tube. 11. The auto-rack railroad car door locking assembly splice of claim 8 , wherein the handle connection assembly includes two spaced apart side walls and an upside down U shaped connection wall. 12. The auto-rack railroad car door locking assembly splice of claim 8 , wherein the cam assembly includes a lower cam structure including a tubular central body, a lower locking tongue connected to and transversely extending from one side of the tubular central body, and a rear lug connected to and transversely extending from an opposite side of the tubular central body. 13. An auto-rack railroad car door locking assembly splice comprising: (a) an extension tube having opposing top and bottom ends, the extension tube including a cylindrical elongated wall having an inner surface defining an inner diameter of the extension tube, an outer surface defining an outer diameter of the extension tube, the top end having an upper edge, and the bottom end having a lower edge; (b) a lock rod connection assembly connected to the top end of the extension tube, the lock rod connection assembly including a cylindrical lock rod connection tube including a cylindrical elongated wall having an outer surface defining an outer diameter of the cylindrical lock rod connection tube, a top end having an upper edge, and a bottom end having a lower edge, the outer diameter of the cylindrical lock rod connection tube being smaller than the inner diameter of the extension tube such that bottom end of the cylindrical lock rod connection tube fits into the top end of the extension tube, a top end of the lock rod connection assembly configured to be directly connected to a bottom end of a remaining portion of a lock rod; (c) a cam assembly connected to the bottom end of the extension tube, the cam assembly including a lower cam structure including a tubular central body, a lower locking tongue connected to and transversely extending from one side of the tubular central body, and a rear lug connected to and transversely extending from an opposite side of the tubular central body; and (d) a handle connection assembly connected to the extension tube between the top end and the bottom end of the extension tube, the handle connection assembly including two spaced apart side walls and a connection wall.
