  • Patent number: 3961856
    Abstract: A machine for compacting soil includes a plurality of compacting elements or hammers elevated and lowered by means of a rotary shaft having an arm member for each hammer extending through aligned hammer openings, each arm member being mounted on the shaft eccentrically with respect to the hammer openings and at different radial positions along the shaft. For elongated hammers limiting rollers may be located at opposite side edges thereof and means are provided for rotating the shaft to effect a walking movement of the machine in a forward direction so that, upon such rotation, the hammers are moved successively upwardly as the arm members rotate between a forward horizontal position and an upward vertical position. The hammers are permitted to be moved successively downwardly into contact with the soil as the arm members each rotate beyond their rearward horizontal positions in the case of forward movement of the machine.
