Terms of cable-lifter

chain groove—circumferential groove at the chain centerline to provide clearance for links passing normal to the wildcat shaft centerline.

chain pockets—recesses between the flanges and whelps into which links with flat side orientated parallel to the wildcat shaft centerling lay.

detachable link—a “C” shaped link, closed by means of a pair of closing pieces and a taper pin, and used to join anchor chain lengths and appendages into a continuous length aboard ship.

flanges—circumferential rims on the outside of the whelps, chain pockets, and chain groove.

link grip—the inside dimension of a chain link representing the effective length of a chain link in an assembled chain. Generally four times the nominal size of a stud link anchor chain.

whelps—protrusions on the inside of the flanges of the wildcat that resemble gear teeth and of such shape and dimensions so as to follow the path of the chain, as it enters and leaves the wildcat. Faces of protrusions are separated by the chain groove to permit links with the flat side normal to the wildcat shaft centerline to pass, but blocking links with the flat side oriented parallel to the wildcat shaft centerline.

wildcat—a rotating member specially contoured to receive assembled chain links and connecting links around the
circumference of the member and of suitable strength to impart motion to the chain when rotated.
