  • Patent number: 6203252
    Abstract: A tool is provided for reaming a new bore in the transfer case. The tool has a mounting plate that attaches to the transfer case. A support shoulder projects down from the bottom of the mounting plate. A threaded sleeve is attached to the support shoulder. The threaded sleeve guides a threaded rod with a hex head at one end and a cutting bit at the other end. Once the mounting plate is attached to the transfer case, the cutting bit is aligned with the bore to be reamed in the transfer case. A mechanic can then attach a hex wrench to the hex head at one end of the threaded rod. The mechanic turns the wrench which causes the cutting bit to turn, reaming out a bore in the transfer case. A bushing installer is inserted into the newly reamed bore. Attaching wrenches to both ends of the bushing installer, the mechanic turns the wrenches until the bushing is completely installed in the newly reamed bore.

  • Patent number: 5287994
    Abstract: A dispenser is disclosed including a substantially transparent container or reservoir tube and valving for receiving and selectively dispensing metered quantities of liquid such as water to a plant. A bottom end of the tube is supplied with a valve mechanism that will open upon application of pressure in a axial direction against the ground surface. The valve will reclose upon removal of the axial pressure. An upward end of the container or reservoir tube may be provided with a filler device such as a manually operated water dispensing nozzle. This nozzle may be connected to a source of liquid supply, such as a garden hose. The transparent tube is provided with volume identification markings to facilitate visual identification and dispensation of selected, metered volumes of liquid contained. The discharge volumes may be easily and quickly replenished by the valved filler device.
