A two piece shank structure releasably retains a single central shank tube detachable from the shanks. The shanks are affixed in position on the surface of two double edged flukes. The double edged flukes are attached to a main fluke shaft. The anchor line extends from the boat through the central shank tube where it attaches to a U-shaped bracket. The U-shaped bracket is attached centrally to the main fluke shaft by a rotatable collar. Both shanks are manufactured with an inherent spring biasin...

An anchor connection and retrieving device is disclosed. The device is adapted to be interposed between an anchor and one end of an anchor line, the anchor has a shank, a crown and a plurality of tynes or flukes. The device has a locking assembly including a releasable portion, a locking portion relative to which the releasable portion is releasably coupled. One or more release members are movable between a first position which couples the releasable portion to the locking portion and a second p...

An anchor for anchoring a vessel to an underwater structure. The anchor includes a shaft and at least three inexpensive flukes each attached to the shaft with a tension adjustable release mechanism. In use at least one of the inexpensive flukes grapple onto a portion of the structure securing the vessel in place. If sufficient tension is applied to the anchor line connecting the anchor to the vessel the release mechanism releases the inexpensive fluke to free the anchor without damage to the und...

An anchor has a shank pivotally connected to a fluke structure via a pivot mount for rotation between locked and release configurations. The shank has a locking surface distal from the pivot mount engaging a portion of the fluke structure to resist the rotation in the locked configuration. An elastically deformable member couples the shank to the pivot mount and the rotation of the shank may require the deformable member to be elastically deformed and the locking surface to be displaced toward t...

A tubular shank structure the anchor includes an elongate arm control member which moves lengthwise within a main body of the shank structure. Pivotally mounted arm members may be maintained collapsed along side the anchor shank structure or may be operatively held perpendicular to the shank structure by the arm control member. Upward positioning of the arm control member causes same to disengage the arm member ends to permit the arm members to rotate downwardly relative the shank structure so a...

An article delivery system for vending machines comprising a vending mechanism and a vend rack. The vending mechanism comprises a plurality of vending columns, each having a gate which is disposed out of phase a predetermined amount with at least one other gate, and which is moveably affixed with respect to a vending column. When the gate is in a closed position the articles may be retained in and above the vending mechanism. By periodically causing the gates to move a predetermined amount, one ...

The present invention is intended for the production of long, large diameter tubular blanks (over 5 m in length and over 800 mm in diameter). According to the method, positive pressure of an inert gas is created inside a spinning mold and maintained there in the process of pouring molten metal thereinto. That provides for the equal speeds of the mold rotation and the metal movement within the mold, and thereby promotes the production of tubular blanks with a uniform structure.

A centrifugal casting method is provided for the manufacture of hollow molds and applications of this apparatus and method are provided. A centrifugal casting apparatus has a hollow mold (13) suitable for the centrifugal casting. For the manufacture of cast workpieees by the centrifugal casting method a plurality of mold cavities (14) formed by at least one hollow mold (13) are arranged and driven such that the mold cavities (14) rotate about a common axis of rotation (18). At least three mold c...

A recoverable sea anchor for a vessel wherein the anchor is made from a flexible sheet material with a periphery and a center. A plurality of lines interconnect a plurality of spaced points around such periphery to a ring which in turn is connected via a releasable connecting means to a swivel. A mooring line is then used to connect such swivel to the vessel. The releasable connecting means is operative to release the connection between the swivel and the ring in response to a predetermined load...

An improved marine anchor is disclosed for anchoring a marine vessel with an anchor rode. The anchor comprises a first and a second fluke connected to an anchor stock. An anchor shank has a pivot aperture disposed between a head portion and a tail portion of the anchor shank. The tail portion of the anchor shank may be provided with either an aperture or a slip ring for connecting to the anchor rode. The pivot aperture pivots the anchor shank on the anchor stock in a space between the first and ...
