Abstract: A pivotable bucket comprising a built-in housing containing a rotatable earth moving mechanism secured to an elbow-type power boom of an excavator or vehicle having hydraulic power thereon. The earth moving mechanism is adapted to dig earth both in a horizontal and lateral direction and to force the diggings out of the upper side of the bucket in a continuous controlled flow. The earth moving mechanism is activated by the power plant of a carrier vehicle.

Abstract: This invention of an amphibious air track vehicle consists of five major assemblies. There are two equally spaced and parallel floatable elongated bodies each of which is encompassed by a belt having a plurality of extended space, parallel and laterally disposed floatable cleats; and drive sprockets which rotate the belts about the elongated bodies. Rotation apparatus for the belts is contained within each body; and a plurality of buoyant wheels each having low pressure tires thereon; and secondly wheels being mounted end to end on a single axis to form a floatable box-like wheel unit, there being two separate boxlike wheel units, one at each end of the vehicle and positioned laterally between each of the floatable elongated bodies; and lastly, a body structure that forms a top deck, rectangular in form, that extends over top of both the two floatable elongated bodies and their belts and the two box-like wheel units.
