  • Patent number: 7584806
    Abstract: A support structure for an implement lift cylinder on an earth-working machine. The support structure includes first and second implement lift cylinder supports. The first implement lift cylinder support mounts to the work machine and the second implement lift cylinder support rotatably connects thereto about a first axis of rotation. The second implement lift cylinder support receives the implement lift cylinder and allows rotational movement thereof about a second axis of rotation. The first and second axes are located within a single plane. The dual axes provide stability and adjustability of the implement lift cylinder for different angle configurations of a work implement, such as an earth-working blade.

  • Patent number: 6629808
    Abstract: Mounting pin arrangements are useful for connecting a first and a second structure together. When the pin is inserted in a mounting structure the mounting pin arrangement needs to expand to seal the arrangement to prevent dust and dirt from entering the mounting arrangement. The subject mounting pin arrangement includes a sleeve assembly that has a plurality of sleeve segments and an elastomeric is positioned and connected to adjacent segments and includes an end cap on the end portion of the sleeve. The sleeve includes a tapered bore therethrough. A pair of inserts are positioned in the bore and include tapers that interact with the taper in the bore of the sleeve to expand the sleeve to seal the mounting arrangement. The arrangement of components provides an expandable pin arrangement that will prevent dust or dirt from entering the mounting arrangement to prolong the life of the various components.
