A U-shaped body including spaced apart generally parallel opposite side legs joined at one pair of corresponding ends by a generally semi-circular bight portion whose opposite ends merge smoothly into the adjacent leg ends. The legs are slightly convergent toward the other end thereof and include enlarged slightly angulated terminal end portions which parallel each other. The enlarged terminal ends of the legs are provided with aligned oval bores whose major dimensions extend in the plane of the...

An adjustable billiard cue bridge of usual outline, a horizontal slider at the rear face thereof, integral spring fingers on the slider, a series of recesses in the bridge to receive the spring fingers in releasable latching adjusted position.

A shackling device includes a U-shaped member and a pin. The ends of the U-shaped member are provided respectively with a threaded aperture and an unthreaded aperture. One end of the pin is provided with threads which are to be mated with the threads within the threaded aperture. The unthreaded aperture has a diameter which is larger than that of the portion of the pin which is not provided with threads. At least a portion of the unthreaded aperture is of smaller diameter than the diameter of th...

A shackle for interconnecting chain links comprising an essentially U-shaped member and a cross or tie member receiving the free ends of the legs of the U-shaped member the cross member having a base therein extending in a direction transversely to the direction of the legs of the U-shaped member. A cylindersegment recess in each of the legs of the U-shaped member, is also provided the axis of which recess coincides with the axis of the transverse bore in the cross member. A pin extending in tig...

A releasable shackle for attachment into a chain and comprising a key-shaped pin with opposite shoulders rotatively positioned by the chain link opening through which it is engaged and thereby locked between spaced legs of the shackle, and particularly adapted to be used as a safety chain connector.

A joining shackle or link is provided for joining link chain sections and comprises a link shaped assemblage of members including a detachable member or members enabling the joining link to be fitted on the chain sections. Opposed U-shaped parts (1,2) of the assemblage have abutting flanges (3) provided with wedge surfaces (4)and the assemblage is held together by couplers (5) which preload the wedge surfaces and the flanges. This preloading of the joining shackle enables the shackle to better w...

A safety shackle having a modified U-shaped design comprising first and second arms, first and second cusps, a first slot disposed between the first arm and the first cusp and a second slot disposed between the second arm and the second slot, and a working area disposed between the first and second cusps. A designated chain link is introduced with within one of the slots and is locked within the slot by orienting the contiguous chain links in a plane perpendicular to the designated chain link, t...

In the case of a connecting chain link having two connecting-link parts (1, 2) which are locked in place in the closed position by means of a bolt-shaped locking element (12) which rests in a holder (11) formed by the connecting-link parts (1, 2), the locking element (12) has, in addition to a central spring lock washer (19) which is used to secure its axial position, two further spring lock washers (23, 24) which are arranged in the region of its end and prevent tilting movements of the locking...

The present inventions relate generally to a shackle assembly and a method for installing and/or releasing the shackle assembly subsea. The shackle assembly of the present invention comprises first and second plates mounted on either side of a shackle body eyelet and a shackle pin mounting assembly for use in mounting a shackle pin using a shackle pin pulling tool.

A sprocket chain link designed to connect opposing link ends of a handwheel sprocket chain having a detachable grasping end and a detachable bit end. The sprocket chain master link is used to facilitate replacement or length alterations an existing handwheel sprocket chain used to turn a sprocket handwheel for opening and shutting piping valves. The detachable grasping end of the sprocket chain master link is used to hold a link end portion of a standard handwheel sprocket chain link while the d...
