ABSTRACT:
A vibration tamper device in which a frame having spaced wheels on a horizontal shaft on which a rocker is tiltable in a fore and aft plane and has tamper feet at the opposite ends. An engine supported on the shaft drives a reciprocatory member which is connected to the rocker to oscillate the rocker and cause the tamper feet to engage the ground alternately. A one way clutch is preferably interposed between the rocker and at least one wheel so the device will move as the rocker oscillates.
