Abstract

A compact single wheeled knuckle carrier which may be easily stowed and take up minimal space within the engine while simultaneously being easily maneuverable and robust enough to assist a person in carrying a train knuckle over rough terrain and over distance. The compact single wheeled knuckle carrier has a support member that couples the knuckle to the carrier and can include a slide lock to secure the knuckle to the support member. The compact single wheeled knuckle carrier has a pin holder that carries a pin that is used with the knuckle.

Claims (60)

1 . A knuckle carrier comprising:

a body having a first end and a second end;

a handle at the first end of the body;

a single wheel at the second end of the body;

a knuckle attachment assembly including a support member coupled to the body of the knuckle carrier, the support member configured to carry a coupler knuckle; and

a knuckle pin holder coupled to the body, the knuckle pin holder configured to hold a knuckle pin that is used to connect the coupler knuckle to another coupler knuckle on an adjacent train car when both the knuckle pin and couple knuckle are removed from the knuckle carrier.

2 . The knuckle carrier of claim 1 , further comprising:

a support plate attached to the body proximate the wheel;

wherein the support member extends vertically from the support plate, wherein the support plate and the support member are located on a different side of the body than the pin holder.

3 . The knuckle carrier of claim 1 , further comprising:

a flange attached to the body proximate the wheel; and

wherein the pin holder is connected to the flange and spaced apart from the body.

4 . The knuckle carrier of claim 3 , further comprising:

a top edge of the flange and a bottom edge of the flange;

a support plate attached to the body proximate the wheel;

wherein the top edge of the flange is located at greater vertical height than the support plate; and

wherein the support member extends vertically from the support plate, wherein the support plate and the support member are located on a different side of the body than the pin holder.

5 . The knuckle carrier of claim 3 , further comprising:

a top edge of the flange and a bottom edge of the flange;

a support plate attached to the body proximate the wheel;

wherein the bottom edge of the flange is located at lower vertical height than the support plate; and

wherein the support member extends vertically from the support plate, wherein the support plate and the support member are located on a different side of the body than the pin holder.

6 . The knuckle carrier of claim 3 , further comprising:

a support gusset connected to the body and the support plate, wherein a lower end of the support gusset is located at a lower vertical height than a top edge of the flange.

7 . The knuckle carrier of claim 3 , further comprising:

a support gusset connected to the body and the support plate, wherein a lower end of the support gusset is located at a lower vertical height than a bottom edge of the flange.

8 . The knuckle carrier of claim 1 , wherein the pin holder is on an opposite side of the body than the support member.

9 . The knuckle carrier of claim 1 , further comprising:

a length of the pin holder; and

a length of the support member, wherein the support member is longer than the pin holder.

10 . The knuckle carrier of claim 1 , wherein the body is a singular body, wherein the support member is formed from tubular metal, and wherein the pin holder is formed from tubular metal.

11 . The knuckle carrier of claim 10 , further comprising: an external diameter of the tubular metal that forms the support member, wherein the external diameter is smaller than an internal diameter of an aperture defined in the coupler knuckle.

12 . The knuckle carrier of claim 10 , further comprising:

an internal diameter of the tubular metal that forms the pin holder, wherein the pin holder has an enclosed bottom and an open top so as to receive the pin within a bore of the tubular metal, wherein the internal diameter is larger than an external diameter of the pin that is held by the pin holder.

13 . The knuckle carrier of claim 1 , wherein the handle further comprises:

a first curved portion and a second curved portion;

a straight section located between the first curved portion and the second curved portion;

at least one aperture formed in the straight section, wherein the at least one aperture in the straight section is configured to receive a connector for an attachment that couples with the straight section.

14 . The knuckle carrier of claim 13 , wherein the attachment that connects with the straight section is a cross bar that establishes a T-handle.

15 . The knuckle carrier of claim 1 , wherein the handle is a T-handle.

16 . The knuckle carrier of claim 1 , wherein the handle further comprises:

a first curved portion and a second curved portion;

a straight section located between the first curved portion and the second curved portion;

a cross bar coupled to the straight section, wherein the cross bar is adapted to be gripped by both hands of an operator; and

wherein the second curved portion is located above the cross bar.

17 . The knuckle carrier of claim 1 , wherein the coupler knuckle is supported by the knuckle carrier in a position above the body of the knuckle carrier when the knuckle carrier is operated at an acute angle relative to a ground surface.

18 . The knuckle carrier of claim 1 , further comprising:

a slidable lock plate and lock collar formed as a singular unit, wherein the lock collar slides along the body, wherein sliding movement of the singular movement has a clearance above the support member that is adapted to allow space for the coupler knuckle to be installed on and removed from the support member.

19 . The knuckle carrier of claim 1 , further comprising:

a lock that is operable to lock the coupler knuckle on the support member.

20 . The knuckle carrier of claim 1 , further comprising:

a support plate attached to the body of the knuckle carrier proximate the wheel;

wherein the support member extends vertically from the support plate; and

a slidable lock operable to lock the coupler knuckle in place on the support member, wherein the slidable lock defines an aperture operable to engage at least a portion of the support member, and wherein the slidable lock further comprises:

a lock collar having a thumbscrew aperture defined therethrough; and

a thumbscrew operable to engage the thumbscrew aperture in the lock collar and the body of the knuckle carrier to secure the lock collar and lock plate in position relative to the body of the knuckle carrier;

at least two grips on the handle of the body;

wherein the knuckle carrier is operable to be stored within an engine of a locomotive train;

wherein the coupler knuckle is supported by the knuckle carrier in a position above the body of the knuckle carrier when the knuckle carrier is operated at an acute angle relative to a ground surface; and

wherein the pin is carried by the pin holder in a position below the body of the knuckle carrier when the knuckle carrier is operated at an acute angle relative to a ground surface.
