Abstract:

A sidescreen securement apparatus for auto-rack railroad cars which may be installed by a single person working inside the car, thereby saving time and money, as well as eliminating the danger of falls. The sidescreen-roof securement device comprises a Y-shaped roof engagement member with a lower stem for securement to the sidescreen through one of its perforations with a blind fastener. A first sidescreen-sidescreen securement device takes advantage of the channels formed along the edges of the sidescreens. A channel segment slips into the edge channel of the upper sidescreen and is thereby secured to it. A U-shaped element is welded to the channel segment and a flange extends from the U-shaped member down to the adjacent lower sidescreen and is secured thereto by means of a blind fastener. An alternate sidescreen-sidescreen securement device may also be used to secure adjacent sidescreens and utilizes a U-shaped member having upper and lower flanges for engagement with the upper and lower sidescreens by means of blind fasteners.
