  • Publication number: 20110023336
    Abstract: A lock that includes a wedge that is used to releasably secure separable components of an assembly together. The wedge can be used with a spool. The wedge and spool are threadedly coupled together to drive the wedge into and out of an opening in the assembly without hammering or prying. The direct coupling of the wedge and spool eliminates the need for bolts, washers, nuts and other hardware so as to minimize the number of parts. As a result, the lock is inexpensive to make, easy to use, and unlikely to become inoperative because of lost or broken parts or due to fines or other difficulties encountered in harsh digging environments. Further, the wedge can be driven into the assembly to provide the degree of tightness necessary for the intended operation and/or to re-tighten the assembly after incurring wear during use. A latch assembly is preferably provided to securely hold the wedge in place and avoid an undesired loss of parts during use.

  • Publication number: 20100269379
    Abstract: The present invention relates to an improved ripper boot which includes a carrier section, and a ripper tooth section having a high tensile tip adapted to be press fit into a contact end thereof. In operation, the carrier section is placed over and conformed to fit over a ripper boot shank of a bulldozer, or one or more excavator loader bucket shanks. In using a press fit high tensile tip, less maintenance is required on the ripper boot during operation, which means that the machinery does not need to idle so often, saving considerable time and expense. The reason for this is that the tip is made of a high tensile metal such as tungsten which is less susceptible to wear and tear so it can be used for considerably longer periods before it becomes worn. Furthermore, hard and abrasive rock in front of the tungsten tip has been found to “explode” in its path resulting in the location of precious stones which would otherwise have been missed using conventional equipment.

  • Patent number: RE43693
    Abstract: A coupling arrangement for securing two separable components in an excavating operation includes a wear component, a base component and a lock. The lock has a body having a configuration adapted to be received in a hole in the base component, and a rotatable locking member. The locking member includes a flange that is movable between a locking position wherein the flange holds the lock in the assembly and a release position wherein the flange permits the lock to be removed from the assembly. In the release position, the flange sets within the axial extension of the outline of the body. In the locking position, at least part of the flange sets outside the axial extension of the outline of the body. In one construction, the rotation of the locking member to the locking position tightens the fit of the wear component on the base component.
