  • Apparatus for preventing the transmission of vibrations
    Patent number: 4497078
    Abstract: An apparatus for preventing the transmission of vibrations from one object to another including a first and second frame having a rod attached to one of the frames and the other being slideably mounted to the rod. An air bag or other force transmitting mechanism is attached to one end thereof to one of the frames and abuts the other of the frames.
