  • Patent number: 8783416
    Abstract: A clamp device for mounting a rail device onto a railroad rail includes a clamp body having an upper section and a lower section. The clamp body defines a recess portion between the upper and lower sections and a bore extending through the lower section of the clamp body. A bolt having a first end and a second end extends through the bore of the clamp body. The clamp device also includes a quick release mechanism having a lever arm and a cam member pivotally connected to the second end of the bolt. The lever arm is connected to the cam member and has a clamped position and a released position whereby pivoting the lever arm from the released position to the clamped position draws the first end of the bolt and the clamp body together.
