Abstract

Various embodiments include a vehicle draft key wear protector including a first arm, a second arm spaced-apart from the first arm, a first connector integrally connected to the first arm and integrally connected to the second arm, and a second connector integrally and detachably connected to the first arm and integrally and detachably connected to the second arm, wherein the railroad car draft key wear protector is configured to be positioned on an uninstalled draft key, and is configured to be positioned on an installed draft key in situ.

Claims (32)

1. A vehicle draft key wear protector comprising:

a first arm;

a second arm spaced-apart from the first arm;

a first connector integrally connected to the first arm and integrally connected to the second arm, and the first connector allows the first and second arms to bias outwardly when the first and second arms pass over a draft key; and

a second connector integrally and detachably connected to the first arm and integrally and detachably connected to the second arm.

2. The vehicle draft key wear protector of claim 1 , wherein the first connector includes a generally wedge shaped body integrally connected to the first arm and integrally connected to the second arm such that the first arm and the second arm are configured to be biased apart during installation of the vehicle draft key wear protector on an installed draft key.

3. The vehicle draft key wear protector of claim 1 , wherein the detachable second connector includes a generally wedge shaped body, and the wedge shaped body engages a surface of the first arm and a surface of the second arm.

4. The vehicle draft key wear protector of claim 3 , wherein the detachable second connector is connected with the first arm by a first joint and to the second arm by a second joint.

5. The vehicle draft key wear protector of claim 4 , wherein the first joint has a substantially narrower width than a width of the detachable second connector, and wherein the second joint has a substantially narrower width than the width of the detachable second connector.

6. The vehicle draft key wear protector of claim 1 , wherein the first connector allows the first arm and the second arm to return to an unbiased position after passing a draft key.

7. The vehicle draft key wear protector of claim 6 , wherein the first arm and the second arm each have an inclined surface and the inclined surfaces engage the draft key during installation to bias the first and second arms outward.

8. The vehicle draft key wear protector of claim 6 , wherein the inclined surfaces engage with the second connector when the second connector is attached.

9. The vehicle draft key wear protector of claim 1 , wherein the first arm and the second arm are positioned between a draft key head and a sill or frame component.

10. A vehicle draft key wear protector comprising:

a first arm having a first gripping hand;

a second arm spaced-apart from the first arm and having a second gripping hand, said first gripping hand and said second gripping hand configured to engage a side of a body of a draft key when the first arm and the second arm are mounted on the draft key;

the first arm and the second arm positioned between a draft key head and a sill or frame component; and

a first connector connected to the first arm at an end of the first arm opposite the first gripping hand, and connected to the second arm at an end of the second arm opposite the second gripping hand, and the first and second gripping hands have spaced apart inclined surfaces that engage with an installed draft key to bias first and second arm outward.

11. The vehicle draft key wear protector of claim 10 , wherein the first connector includes a generally wedge shaped body integrally connected to the first arm and integrally connected to the second arm, and the first connector configured such that the first arm and the second arm are biased apart as the first and second arms pass over an installed draft key.

12. The vehicle draft key wear protector of claim 10 , wherein the first connector allows the first arm and the second arm to return to an unbiased position after passing over an installed draft key.

13. The vehicle draft key wear protector of claim 10 , wherein the second connector comprises a first joint that engages with the first arm and a second joint that engages with the second arm.

14. A vehicle draft key wear protector comprising:

a first arm including a first elongated section, a first hand connected to and extending from one end of the first elongated section, and a second hand connected to and extending from a second opposite end of the first elongated section;

a second arm spaced-apart from the first arm, the second arm including a second elongated section, a first hand connected to and extending from one end of the second elongated section, and a second hand connected to and extending from a second opposite end of the second elongated section;

the first arm and the second arm positioned between a draft key head and a sill or frame component;

a first connector integrally connected to the first hand of the first arm and integrally connected to the first hand of the second arm; and

a second connector integrally connected to the second hand of the first arm and integrally connected to the second hand of the second arm and the second connector detachable from the first and second arms to form a gap between the first and second arms,

wherein the first arm is configured to engage a first side of a body of a draft key, the second arm is configured to engage a second side of the body of the draft key, the first connector is configured to engage a third side of the draft key, and the second connector is configured to engage a fourth side of the draft key.

15. The vehicle draft key wear protector of claim 14 , wherein the first connector includes a generally wedge shaped body and a first surface of the wedge shaped body engages with the first arm and a second surface of the wedge shaped body engages with the second arm.

16. The vehicle draft key wear protector of claim 15 , wherein the second connector includes a generally wedge shaped body and forms a wedge shaped gap when detached.

17. The vehicle draft key wear protector of claim 14 , wherein when the second connector is detached, inclined surfaces of the first arm and the second arm are exposed, and

the inclined surfaces engage a draft key to bias the first and second arms outward during installation of the vehicle draft key wear protector.
