ABSTRACT:
An anchor device adapted to be buried in a bed of material and including an anchor head comprising a generally hollow cylindrical body having an upper portion adapted to be releasably secured to a hollow placement stem connected to a supply of fluid under pressure. A lower portion of the anchor head has a tapered nose and at least one downwardly oriented jet aperture is provided in the lower end of the nose and a plurality of upwardly-angled jet apertures are provided in the walls of the nose for transmitting fluid into the bed material surrounding the nose to fluidize the material and drive the head into the bed. A fin assembly is mounted on the anchor head intermediate the top and bottom portions and comprises a plurality of fins and a collar and bracket arrangement for mounting a foot portion of each of the fins for rotation between a folded position generally parallel to the axis of the anchor head and an unfolded position at a substantial acute angle to the axis. An anchor line assembly is provided including an anchor line and a ring and cable arrangement fastening the anchor line to the fin assembly to enable the anchor head and fin assembly to be partly retracted from the bed to unfold the fins and thereby set the anchor device in the bed. A placement stand assembly is provided for the anchor and includes a horizontal table with an aperture therethrough receiving the placement stem. The placement stand assembly is adapted to rest on the surface of the bed of material for holding the placement stem in a vertical position as the anchor assembly and placement stem are being driven into the bed. Cooperative screw threads are carried on the distal end of the placement stem and on an upper portion of the anchor assembly for releasably connecting the placement stem and anchor assembly. A stop plate is carried on the placement stem at a preselected distance from the distal end for stopping the burying of the anchor assembly when the stop plate encounters the table on the placement stand assembly. A spring powered turntable is carried on the table and is operable by the stop plate for separating the screw threads to separate the anchor assembly and the placement stem.
