Abstract
A railroad crossing gate drive mechanism has an adjustable gate arm support in the form of a split hub mounted on the external portion of a drive shaft. A fixed section of the split hub is keyed to the drive shaft and has threaded bolt holes therein. A moveable section of the split hub mounts a gate arm connector and has arcuate slots cut on the same bolt circle as the fixed section's bolt holes. Cap screws extend through the arcuate slots and into the bolt holes. The horizontal position of the gate arm connector can be adjusted due to the loose fit afforded by the arcuate slots on the cap screws. When the gate arm connector is located in the desired horizontal position, the cap screws are tightened to lock the split hub sections together.
