| 20080232919 | AUTO-RACK RAILROAD CAR VEHICLE WHEEL CHOCK - A vehicle wheel chock for a vehicle restraint system for an auto-rack railroad car which secures a vehicle in the auto-rack railroad car. The vehicle wheel chock is configured to be positioned on a grating adjacent to a tire of the vehicle. | 09-25-2008 |
| 20080253854 | RAILROAD CAR COIL RESTRAINT SYSTEM - A transverse railroad coil car coil restraint apparatus or system which includes a plurality of coil restraints attachable to each trough in a transverse railroad coil car to reduce the sideways shifting of coils positioned in the troughs. In certain embodiments, the coil restraints are attached in each trough and extend across the transverse coil car. In other embodiments, the coil restraints are attached in each trough along the length of the trough. In certain embodiments, when a coil is positioned in the trough, the coil compresses certain of the coil restraints and does not compress other of the coil restraints which prevents the sideways shifting of the coil during movement of the transverse coil car. In other embodiments, when a coil is positioned in the trough, the coil compresses certain of the compression members and does not compress other of the compression members which prevents the sideways shifting of the coil during movement of the transverse coil car. | 10-16-2008 |
| 20090064454 | RAILROAD CAR DOOR PIVOT ASSEMBLY - An improved auto-rack railroad car door pivot bolt assembly for an auto-rack railroad car including a roof having a roof stiffener and a door having a hood. The auto-rack railroad car door pivot bolt assembly ties the hood of the door of the auto-rack railroad car to the roof stiffener on the roof of the auto-rack railroad car to reduce relative movement of the hood and the roof stiffener to each other and prevents wear of the shoulder bolt, the hood, and the roof stiffener. | 03-12-2009 |
| 20090129884 | RAILROAD CAR COIL RESTRAINT SYSTEM - A transverse railroad coil car coil restraint apparatus or system which includes a plurality of coil restraints attachable to each trough in a transverse railroad coil car to reduce the sideways shifting of coils positioned in the troughs. In certain embodiments, the coil restraints are attached in each trough and extend across the transverse coil car. In other embodiments, the coil restraints are attached in each trough along the length of the trough. In certain embodiments, when a coil is positioned in the trough, the coil compresses certain of the coil restraints and does not compress other of the coil restraints which prevents the sideways shifting of the coil during movement of the transverse coil car. In other embodiments, when a coil is positioned in the trough, the coil compresses certain of the compression members and does not compress other of the compression members which prevents the sideways shifting of the coil during movement of the transverse coil car. | 05-21-2009 |
| 20090245962 | CHOCK STRAP RETAINER FOR AUTO-RACK RAILROAD CAR VEHICLE WHEEL CHOCK - A vehicle wheel chock strap retainer that provides that different straps of different dimensions will remain securely affixed to a torque tube of a wheel chock when the chock strap retainer is inserted into the torque tube. | 10-01-2009 |
| 20100104391 | AUTO-RACK RAILROAD CAR VEHICLE POSITIONING AND DAMAGE PREVENTION SYSTEM - An auto-rack railroad car vehicle positioning and damage prevention system which reduces or eliminates damage to the front and rear ends of the vehicles which can occur while the vehicles are being loaded in an auto-rack car. In one embodiment, the auto-rack car vehicle positioning and damage prevention system includes a plurality of vehicle positioning devices mountable in the auto-rack car to enable a loader to determine the distance between the vehicle the loader is driving and the vehicle positioned in front of the vehicle the loader is driving, and to enable the loader to see the position of the tires relative to a grating in the auto-rack car on which the tire is positioned. | 04-29-2010 |
