Abstract

This invention relates to a railroad car for use in transporting railroad ties. A flat bed is provided with siderails which extend upwardly along each side of the bed. Each of the siderails comprises vertically extending posts and horizontally extending rails with some of the rail sections being removable to accommodate unloading of the ties. The removable rail sections are disposed so that upper and lower rails on one sidewall are removable while an intermediate rail section on the opposite sidewall is removable. This helps to insure the structural integrity of the car.

Description

This invention relates generally to railroad cars and, more particularly, to a car especially designed for handling railroad ties.

It is, of course, well known to utilize large timbers commonly referred to as ties to secure rails to a bed to form a railroad track. Replacement of railroad ties is a continuous job which all railroads must perform. Railroad ties are normally carried from the supply yard along the line to a location where they are needed. Because of the nature of railroad ties, they are normally transported on flat cars having sidewalls or rails to hold the load. When the location is reached where the ties are needed, they are normally thrown over the sidewalls of the car by workers to first one side of the track and then the other. It is, of course, possible to use mechanical lifts for unloading the cars, although this is generally more time consuming and not economically efficient since this type of cargo can be unloaded by manual labor.

It is, however, very demanding work to unload railroad ties by hand and, in some cases where workers do not follow recommended safety procedures, back strains have been known to occur.

It is, therefore, a primary object of the present invention to provide a railroad car especially designed for hauling railroad ties which has removable side panels to permit the ties to be unloaded without the need to lift the ties over the sidewalls of the car.

As a corollary to the above object, an important aim of the invention is to provide a railroad car especially designed for handling railroad ties which makes unloading of the ties safer and faster than manual unloading methods heretofore utilized.

It is also an object of the invention to provide a railroad car having removable side panels to accommodate unloading of ties from the car and where the sidewalls are constructed in such a manner that the removable panels do not jeopardize the structural integrity of the car.

Still another one of the objectives of my invention is to provide a railroad car of the type meeting the foregoing aims and objects which provides a quick release mechanism for the removable side panels.

Other objects of the invention will be made clear or become apparent from the following description and claims when read in light of the accompanying drawing wherein:

FIG. 1 is a side elevational view, partly broken away, of a railroad car according to the present invention;

FIG. 2 is a fragmentary cross-sectional view taken generally along line 2--2 of FIG. 1; and

FIG. 3 is a horizontal cross-sectional view of the railroad car of the present invention taken along line 3--3 of FIG. 1.

Referring initially to FIG. 1, a railroad car according to the present invention is designated generally by the numeral 10. Car 10 comprises a flat bed 12 mounted on wheel and axle assemblies 14. Extending upwardly at both of the ends of car 10 are bulkheads 16. Extending between the bulkheads on opposite sides of bed 12 are first and second siderails designated generally by the numeral 18. As both siderails are identical, only one will be described in detail.

Each siderail 18 comprises a plurality of spaced apart vertically extending upright posts 20 and a plurality of horizontally extending spaced apart rails 22 and 24. Rails 22 and 24 extend between adjacent posts and between the end posts and the bulkheads 16. A cap rail 25 runs the length of bed 12 along the tops of posts 20.

Some of the rail sections 22 are removably mounted between adjacent posts 20 by means of u-shaped brackets 26 (FIG. 2). Brackets 26 are rigid with posts 20 and each of the brackets is provided with a lip 28 for retaining one end of the removable rail section 22. The opposite end of bracket 26 is provided with a through opening 30 and an integral sleeve 32 aligned with and extending upwardly from the opening. It is to be noted that sleeve 32 is disposed at a slight acute angle relative to the vertical plane of rail 22.

The sleeve receives a keeper pin 34 which is welded at one end to a retaining chain 36. Chain 36 is in turn welded at its opposite end to the adjacent post 20.

It is to be noted that the brackets 26 and their associated retaining pins 34, which removably mount selected rail sections 22, are disposed so that upper and lower rail sections between adjacent posts on one sidewall are removable while another removable rail section on the opposite sidewall is disposed at a vertical height intermediate the upper and lower removable sections on the first sidewall. At a point spaced lengthwise from these first removable sections, the first sidewall will have a removable rail section which is at a height intermediate upper and lower removable rail sections on the opposite sidewall. In this manner, the removable sections are alternated in positions along the length of the car so as to maintain the structural integrity of the sidewalls. It is also to be amphasized that, while at least one removable section has been shown in the drawing between each adjacent pair of posts 20, this has been done only to illustrate the pattern for locating the removable sections. In actual practice, it would not be necessary in many instances to have a removable section between each adjacent pair of posts and one or more sections between adjacent posts could be without any removable sections. Manifestly, by locating the various removable sections at different heights, unloading of the railroad ties from within the car is greatly facilitated.

When railroad ties are to be unloaded, rail sections 22 are removed as necessary by simply pulling pins 34 from sleeves 32 thus freeing rail sections 22 to be removed from brackets 26. Chains 38 are welded to rail sections 22 and to posts 20 so that, once removed, the rail sections 22 can be allowed to simply hang along the side of the car as illustrated in FIG. 1. When it is time to replce the removable rail sections 22, they are placed back inside of brackets 26 and keeper pins 34 are again inserted into sleeves 32. Because sleeve 32 is disposed at an angle relative to the vertical, each pin 34 will tend to wedge itself against the upper end of rail 22 thus assuring a tight fit and also helping to retain the pin in its holding position.

While the invention has been particularly described with regard to transporting railroad ties, it will be appreciated that the railroad car may find utility in transporting other similar types of cargo.

Claims

I claim:
