Anchor comprising a fluke and a shank which at a first end is attached to the fluke and a second end that is situated opposite to the first end, is provided with means for attachments of the anchor to a penetration line or anchor line, in which the shank comprises two shank legs, which at the second end are connected to each other using a pin, in which the portion of the pin situated within the shank legs also serves as connection means for an end link or end shackle of the penetration line or a...

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 marine anchor having a shank connectible to an anchor rode at one end and having a double ploughshare fluke rigidly mounted at the other end thereof is described. The fluke consists of two symmetrically mounted part-cylindrical blades disposed on each side of a central ridge in the medial plane of the shank and extending from a forward apex to divergent trailing ends. A ballast weight is mounted under the convex surfaces of the blades and contained within the tangential plane to the convex sur...

An anchor in which an L-shaped shank has a single trapeziform fluke pivotally secured to the shorter leg of the L provides a larger surface area for the palm of the fluke. The fluke is configured such that a center of force is directed perpendicularly to the shorter leg of the L to minimize the tendency of the anchor to move sideways or crab.

An anchor with pivoted flukes and a track upon which an anchor line is slidably connected to the anchor has a pair of fluke drivers adjacent the flukes which produce a significant included angle of the flukes with respect to the bed of a body of water. This included angle of the flukes enables them to rapidly penetrate and set in a bed of a body of water even under hard pan bed conditions. Typically, the anchor sets into the bed of a body of water within ten feet of anchor movement relative to t...

In an anchor the stabilization arms transversely extending in the plane of the flukes are constructed as bars of quadrilateral cross-section having forwardly directed faces forming an acute angle with each other instead of rod-shaped. These bars are so formed that with a considerably smaller length of the stabilization arms the same stabilizing effect is obtained.

A marine anchor release mechanism that can be utilized on several pre-manufactured claw, plow or fluke type anchors for unsnagging the anchors from underwater obstructions. The release mechanism consists of two blade type brackets that run parallel to the shank of an anchor and connected to a rear portion of the anchor. A shear pin is installed through the parallel blade type brackets and the shank or an upper extension of the anchor that is sandwiched there between. The release mechanism is des...

A multi-bladed knife is formed with three parallel blades attached to a handle by means of a screw rod and spring arrangement mounted at front and rear portions of the handle, respectively. The screw rod fastens the blades to the front end of the handle and is rotatable to adjust the transverse spacing between the blades. Application of manual gripping pressure to the rearward portion of the handle against spring bias serves to direct the outer blades into a diverging angle relative to the handl...

A marine anchor has an anhedral fluke with a shank attached thereto including an anchor line attachment point. A rear plate assembly behind the fluke is inclined at an obtuse angle .alpha. to the fluke and serves to provide a turning moment about the attachment point countering turning moments produced by friction effect on the fluke and the shank and by edge resistance during anchor burial to give improved anchor holding power while soil escapes the passage between the rear assembly and the flu...
