Abstract

Claims (36)

1. An air hose hanger for supporting flexible air hoses of a trainline braking system of a rail car, the air hose hanger comprising:

a head including a mounting plate for mounting the air hose hanger to a coupler of a rail car, the mounting plate including first and second apertures for receiving first and second bolts for attaching the mounting plate to the coupler;

an arm removably attached to the head, the arm comprising:

a first arm removably attached to the head and extending in a substantially vertical direction away from the head; and

a second arm integral with the first arm and extending in a horizontal direction substantially parallel to an axis of the coupler;

first and second inserts received in first and second lightener holes which are preformed in the coupler, the first and second lightener holes extending from a front opening in the coupler to a rear opening in the coupler,

wherein the front opening is larger than the rear opening, and wherein the first and second inserts are sized such that they are received in the front opening and are displaceable in the first and second lightener holes, but are larger than the rear openings such that they cannot pass there through, and

wherein the first and second inserts are disposed in the lightener holes adjacent the rear openings and each include a threaded aperture for receiving the first and second bolts, respectively, for securing the head of the hanger to the coupler; and

an extension extending from the head in a direction generally away from the second arm, the extension including an aperture configured for alignment with the third aperture preformed in the underside of the coupler and attached to the coupler via a bolt passing through both apertures,

wherein the head and the arm include respective connector plates having a mating dove-tail connection for connecting the arm and head together, wherein the mating dove-tail connection ensure proper alignment of the head and arm prior to attachment.

2. The air hose hanger of claim 1 , wherein if the arm and head are properly aligned, apertures formed in the respective connector plates will align and allow bolts to pass there through, and wherein if the arm and head are not properly aligned, apertures formed in the respective connector plates will not align and prohibit bolts from passing there through.

3. The air hose hanger of claim 1 , wherein the first arm comprises a tab having an aperture formed thereon, the aperture configured for receiving a hook of an elastic air support hanger attached to a flexible air hose.

4. The air hose hanger of claim 1 , further comprising a hose connection rotatably attached to an end of the second arm for rotatably supporting a flexible air hose attached to the hose connection.

5. The air hose hanger of claim 4 , wherein the end of the second arm includes a hollow cylindrical member configured for receiving a cylindrical member of the hose connection, wherein the cylindrical member of the hose connection is attached to the hollow cylindrical member for rotatable movement of the hose connection with respect to the hollow cylindrical member.

6. The air hose hanger of claim 1 , where the arm includes a “+” or “x” shaped cross-section.

7. The air hose hanger of claim 1 , wherein the rail car comprises a cushioned car, and wherein the coupler comprises a cushioned coupler.

8. The air hose hanger of claim 1 , wherein the head and arm are comprised of ductile iron, heat treated ductile iron, or austempered ductile iron or steel for weldable designs.

9. An air hose hanger for supporting flexible air hoses of a trainline braking system of a rail car, the air hose hanger comprising:

a head including a mounting plate for mounting the air hose hanger to a coupler of a rail car, the mounting plate including first and second apertures for receiving first and second bolts for attaching the mounting plate to the coupler;

an arm removably attached to the head, the arm comprising:

a first arm removably attached to the head and extending in a substantially vertical direction away from the head; and

a second arm integral with the first arm and extending in a horizontal direction substantially parallel to an axis of the coupler;

wherein the head is attached to the coupler at three preformed holes formed in the coupler, the three preformed holes comprised of first and second lightener holes preformed in the coupler, and a third aperture preformed in a tab on an underside of the coupler,

wherein the head and the arm include respective connector plates having a mating dove-tail connection for connecting the arm and head together, wherein the mating dove-tail connection ensures proper alignment of the head and arm prior to attachment.

10. The air hose hanger of claim 9 , wherein if the arm and head are properly aligned, apertures formed in the respective connector plates will align and allow bolts to pass there through, and wherein if the arm and head are not properly aligned, apertures formed in the respective connector plates will not align and prohibit bolts from passing there through.

11. The air hose hanger of claim 9 , wherein the first arm comprises a tab having an aperture formed thereon, the aperture configured for receiving a hook of an elastic air support hanger attached to a flexible air hose.

12. The air hose hanger of claim 9 , further comprising:

first and second inserts received in the first and second lightener holes which are preformed in the coupler, the first and second lightener holes extending from a front opening in the coupler to a rear opening in the coupler,

wherein the front opening is larger than the rear opening, and wherein the first and second inserts are sized such that they are received in the front opening and are displaceable in the first and second lightener holes, but are larger than the rear openings such that they cannot pass there through, and

wherein the first and second inserts are disposed in the lightener holes adjacent the rear openings and each include a threaded aperture for receiving the first and second bolts, respectively, for securing the head of the hanger to the coupler.

13. The air hose hanger of claim 12 , further comprising an extension extending from the head in a direction generally away from the second arm, the extension including an aperture configured for alignment with the third aperture preformed in the underside of the coupler and attached to the coupler via a bolt passing through both apertures.

14. The air hose hanger of claim 9 , further comprising a hose connection rotatably attached to an end of the second arm for rotatably supporting a flexible air hose attached to the hose connection.

15. The air hose hanger of claim 9 , wherein the end of the second arm includes a hollow cylindrical member configured for receiving a cylindrical member of the hose connection, wherein the cylindrical member of the hose connection is attached to the hollow cylindrical member for rotatable movement of the hose connection with respect to the hollow cylindrical member.

16. The air hose hanger of claim 9 , where the arm includes a “+” or “x” shaped cross-section.

17. The air hose hanger of claim 9 , wherein the rail car comprises a cushioned car, and wherein the coupler comprises a cushioned coupler.

18. The air hose hanger of claim 9 , wherein the head and arm are comprised of ductile iron, heat treated ductile iron, or austempered ductile iron or steel for weldable designs.
