Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an apparatus for holding rail applicator bars for lubricating railroad rails.

2. Description of Related Art

In the operation of railroads, it has long been the practice to apply grease or friction-modifying materials onto railroad rails, such as to the top of rails or sides of the rails at curves, turnouts, switches, and in some cases, the sections of the track immediately before a switch, and periodically spaced along the length of the track. Such lubricants and friction modifying materials, such as grease, can either reduce or increase the friction where necessary, to improve train performance and reduce wear on both the rails and the train wheels. Grease is typically pumped from a nearby central pump station to a rail applicator device for applying grease to the rails. This pump station is typically housed in an enclosure box. Two such devices used for applying friction-modifying material and/or lubricant to the top of the rail is disclosed in International Publication No. WO 00/61418 entitled “Top of Rail Applicator” and U.S. Pat. No. 5,394,958, entitled “Rail Lubrication Apparatus” which are hereby incorporated by reference.

The rail applicator device as disclosed in the above reference includes a rail applicator bar (oftentimes referred to as a “wiping bar”) to provide and/or direct lubricant towards a surface of the rail. When maintenance is performed on the rail or rail applicator device, the wiping bar is removed and/or replaced. The old wiping bars are typically scattered on the side of the railroad tracks. These wiping bars, which can later be cleaned and/or repaired, typically become damaged while scattered on the side of the railroad tracks before maintenance personnel are able to re-install the wiping bars. It is desirable to have a storage area nearby to hold the removed wiping bars until repairs can be performed on the adjacent rail system or rail applicator device.

SUMMARY OF THE INVENTION

The present invention provides for a holder for holding a rail applicator bar. The holder includes a frame defined by a pair of spaced apart side members attached to each other via an upper member and a lower member. At least one transversely extending support member is attached to each of the side members, wherein a rail applicator bar is adapted to be supported on each of the respective support members. The holder further includes a hook attached to the upper member of the frame, wherein the hook is adapted to hang over a top of an upright surface. The holder can be removably or permanently attached to an enclosure.

The present invention provides for a method of storing a rail applicator bar at a railroad installation. The method includes the steps of removing a wiping bar from a railroad lubrication system and placing the wiping bar on a holder as previously described such as to perform maintenance on the adjacent railroad rail system. Next, the wiping bar is removed from the holder, and subsequently replaced back into the railroad lubrication system.
