摘要： 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 biasing in the material, allowing them to be slightly separated for snap in connection of the central shank tube, and also maintains pressure against the central shank tube retaining it in position under normal use. Once the anchor has become snagged under a log or similar underwater snag it may be retrieved by pulling the anchor line at an angle relative to the shanks with the pull needing to be generally opposite in direction to which the anchor is suspected of sliding under a snag. With sufficient tension sometimes coupled with a jerk of the anchor line, the central shank tube will pop-out from between the two spring biased shanks allowing the anchor line to pivot with the U-shaped bracket. The anchor line through the middle of the shank tube and attaching to the rotatable U-shaped bracket allows the anchor to be pulled back out from underneath a snag in the opposite direction from which it was moving when snagged.

摘要翻译： 两片柄结构可释放地保持可从柄部拆卸的单个中心柄管。 将柄固定在两个双刃叉头的表面上。 双刃刺吸附在主要的吸头轴上。 锚线从船上延伸穿过中心柄管，在其附接到U形支架。 U形支架通过可旋转的轴环中心连接到主要吸头轴。 两个柄都被制造成在材料中具有固有的弹簧偏压力，允许它们被轻微分离以与中心柄管连接，并且在正常使用下保持对中心柄管的压力保持在适当的位置。 一旦锚固件已经在木材或类似的水下锚杆处被阻塞，其可以通过相对于柄部以一定角度拉动锚定线而被拉回，其中拉需要大致相反的方向，锚固件被怀疑在锚杆下方滑动 。 由于有足够的张力有时与锚线相加，中心柄管将从两个弹簧偏置的杆之间弹出，从而允许锚定线与U形支架枢转。 穿过柄管中间并连接到可旋转的U形支架的锚线允许锚固件在被阻止时沿与其移动的相反方向从下面的钩子中被拉回。
