  • Patent number: 3990535
    Abstract: This vibration damping device is of a character to minimize the shaking or vibrating of levers, particularly gear shift levers on heavy trucks and other heavy machinery, which when operated over rough terrain at high speed, creates a noise that becomes almost unbearable, resulting in great fatigue on the part of the operator. The present arrangement utilizes an aggregate, shot, or a metallic material within the compartments of a device which may be secured around the lever, as by a zipper, a draw string and tape, so that the sudden and high frequency vibrations are minimized and dampened without interfering with the operation of the gear shift lever. The compartments of the device are divided longitudinally to maintain the aggregate or shot evenly distributed longitudinally. The compartments are also divided transversely, so when fastened around a gear shift lever, they will form circumferential pockets. The device is easily mounted on a gear shift lever and may be removed in a minimum of time.
