Abstract: A pair of tension springs are connected and oriented in such manner, relative to a horizontal-axis vehicle gate, that the gate is effectively and economically spring-biased to a predetermined closed position. A precisely-controllable hydraulic damper mechanism prevents the spring-biased gate from bumping the undersides of motor vehicles passing thereover, and then releases to achieve the combined benefits of (1) minimized time period during which the gate remains open after vehicles pass thereover, and (2) maximized effectiveness relative to the latching mechanism of the gate. The release means compensates automatically for conditions under which long tandem trucks, or strings of automobiles or trucks, pass over the gate. Such automatic compensation, and other types of damper operation, are achieved without causing cavitation of the hydraulic fluid.

Abstract: A vehicle gate is mounted for pivotal movement about a horizontal axis which is generally coincident with the surface of the roadway, and spring means are provided to normally maintain the gate in an upright position. A crank is nonrotatably associated with the pivot shaft for the gate, and has a notch therein adapted to receive a latch bar. A lock and operating mechanism is so located that it is adjacent the passenger compartment of the vehicle when the vehicle is stopped on an approach side of the gate. Mechanism is provided for maintaining the latch bar in elevated condition and out of the notch, after unlocking and operation of the lock and operating mechanism, without the necessity of driving the vehicle against the gate. Thus, the operator (driver) may both unlock and lock the lock mechanism without moving the vehicle at all, yet the gate will relatch, after driving of the vehicle thereover and therethrough, without the necessity of any further action on the part of the operator. The spring means and the mechanisms are all located above ground, thus eliminating the necessity for making substantial excavations when the vehicle gate is constructed, and preventing the possibility of malfunction caused by freezing of water in excavated regions.
