Abstract: A height adjustable jack piling assembly has a piling with a top and a bottom. A hinge axis is disposed on the top and a bearing plate is disposed at the bottom. A height adjustment mechanism extends upwardly from the bearing plate and through the piling to raise the piling, and the corresponding hinge axis, by operating the height adjustment mechanism from the top. The method includes placing a jack piling assembly and second lower piling, each having a hinge axis, into the earth and operating the height adjustment mechanism of the jack piling assembly to align the hinge axes.

Abstract: A structural column assembly of the type used for erecting building structures and the like is bedded in a concrete footing formed in situ in an earthen hole. The column assembly includes a post whose bottom end is suspended above a floor of the hole by a stilt. The stilt includes a plurality of legs which extend from the post's bottom end and grip the hole floor through a plurality of cleats. The cleats help stabilize the column assembly during the concrete pour operation so that it does not shift out of position. The stilt legs are provided with a base pad, which is set below the bottom end of the post at a predetermined distance so that the concrete footing can be poured in a single operation immediately after the hole is formed. The stilt can accommodate posts made from wood, pre-cast concrete or any other known construction material. The stilts can be manufactured from formed flat steel or commercially available angle iron and channel stock.

Abstract: An assembly for mounting various work tools, e.g., a backhoe, to a pair of parallel frame members (28) of a vehicle (20). A pair of parallel main beams (26) extend transversely across the frame members (28) and a telescoping stabilizing leg (24) extends downwardly from each end of each of the main beams (26). Four posts (48) extend from the main beams (26) for connecting the main beams (26) at spaced positions along the pair of parallel frame members (28). Each of the posts (48) is L-shaped in cross section with one flange thereof welded to the associated main beam (26) and the other flange attached to the vehicle (20) frame members (28). A pair of bearing blocks (50) are disposed on a first leg cross-beam (42) for pivotally supporting a and a pair of hydraulic cylinder-pistons (52) are attached to a main cross-beam (40) for pivoting the backhoe about the bearing blocks (50).
