Abstract: A vehicle gate is mounted for pivotal movement about a horizontal axis which is generally coincident with the surface of the roadway, and counterweights are provided to normally maintain the gate in an upright position. A disc is nonrotatably associated with the pivot shaft for the gate, and has a notch therein adapted to receive a pivotally-mounted latch bar. A lock mechanism is so located that it is adjacent the passenger compartment of the vehicle when the vehicle is stopped on the approach side of the gate. Such mechanism is adapted to be operated by the vehicle driver to effect lifting of the latch bar out of the notch. The driver then drives the vehicle against and over the gate, following which the gate moves automatically to its upright condition and becomes locked without need for further action by the driver. The locking of the lock mechanism is effected by the driver while the vehicle is still near (but not at) the position at which it is located while the lock mechanism is being unlocked, but the gate does not actually lock until after the vehicle is driven therethrough.

Abstract translation: 车门被安装成围绕水平轴线枢转运动，该水平轴线大致与道路的表面重合，并且配重设置成将闸门正常地保持在直立位置。 盘不可旋转地与用于门的枢转轴相关联，并且其中具有适于容纳枢转地安装的闩锁杆的凹口。 当车辆在门的接近侧停止时，锁定机构被定位成使其邻近车辆的乘客舱。 这种机构适于由车辆驾驶员操作以实现闩锁杆从凹口中的提升。 然后，驾驶员驾驶车辆抵靠门的上方，随后门自动移动到其直立状态并被锁定，而不需要驾驶员进一步的动作。 锁定机构的锁定是由驾驶员进行的，同时当锁定机构被解锁时，车辆仍位于它位于的位置（但并非位于）处，但是在车辆被驱动之后，门实际上并不锁定 通过。
