Patent attributes
Several hammerless pin assemblies for coupling pieces of heavy equipment include a pin that uses a detent to engage the pin between the pieces of heavy equipment. In one embodiment, a pin is inserted between a tooth adapter and a tooth, and rotates between a disengaged position in which the tooth can be applied and removed from the tooth adapter, and an engaged position in which the pin locks the tooth on the tooth adapter. In another embodiment, a pin receives two spindles which slide into and out of an internal hollow in the pin to present or hide an abutment for coupling the two pieces of heavy equipment. In yet another embodiment, a pin and a cap cooperate to capture a washer which prevents removal of the pin from between the heavy equipment and thereby couples the pieces of heavy equipment to each other.
