  • Mechanism for mounting impact tool
    Patent number: 4724912
    Abstract: An improved mechanism for mounting an impact tool on the boom of a power shovel or the like. A mounting member is bonded to each side of the vibration insulating rubber member. The bonded surface between the rubber and the mounting member at at least one side of the rubber is oblique with respect to the axis of the impact tool. This reduces the shearing load to the vibration insulating rubbers, prolongs their life, and lessens the fear of the rubbers peeling off the mounting members.
