A Throat or Round Seizing
This seizing is used for many purposes, such as inside and outside clenches, strops of blocks, turning in lower or topmast rigging and stays, seizing the eyes of rigging, &c. All small rope to be used for seizings should be well stretched for the purpose.
To Pass a Throat or Round Seizing
Splice an eye in one end of the seizings, take it round both parts of the shrouds, and pass seven turns ; working towards the standing part of the shroud, reeve the end back between the turns of the seizing already passed (which are called the lower turns), and up through the eye of the standing part of the seizing, and it will be in the right position to commence passing the six upper turns, or riding turns, which will exactly come between the parts of the lower turns ; care should be taken to heave each lower turn of the seizing well taut by means of a Spanish windlass, and the upper turns well taut by hand. After passing the sixth and last riding turn, pass the end down between the two last turns of the lower turns and heave it hand taut. Then take a round turn round all parts of the seizings, heave it well taut with a Spanish windlass, and secure with a clove-hitch, one part of the clove-hitch being each side of the round turn, expend the end in round turns round the end of the shroud, and secure the end with a yarn. Any number of lower turns can be taken, the riding turns must always be one less in number ; 7 or 9 are the numbers of lower turns generally taken in turning a dead-eye in, or seizing the eyes of rigging.
To Pass a Quarter or Flat Seizing.
Q. How do you pass a quarter or flat seizing, and at what distance from the throat-seizing.
A. The width of the throat-seizing, or about 4 ins. from it. It is about half an inch less in size than a throat-seizing. It is passed and finished off in a similar way to the throat-seizing, each turn being hove well taut, but has no riding turns.
The reason of having an end part left after the throat and quarter seizings are finished off with a clove-hitch is in case of having to turn the lower rigging in at any future time, so the same seizing would do again.
Q. In turning a dead-eye, in wire rigging, what seizings you use?
A. A racking and end seizing, the racking seizing forming, as it were, a throat and quarter seizing.
The standing part of the seizing is made fast to the standing part of the shroud with an eye-splice. Thirteen racking turns are then passed from the eye towards the end, leaving sufficient space between each racking turn for a roundabout tern to lie. After the thirteen racking turns are passed, the roundabout turns are passed from the end towards the eye, each roundabout turn being passed between the racking turns ; when the last roundabout turn is passed, the end is passed up between both parts of the shroud, that is between the standing part and end, really for passing the cross turns, which are passed by taking the end along the seizing and passing it down between the seventh and sixth turns along the seizing, again towards the eye, up between the two parts of the shroud as before, and again drawn between the seventh and sixth turns, then round the other way, over the thirteenth turn, repeating that also twice.
This also applies to wire stays.
The End Seizing
This is merely a flat seizing.
A Rose Lashing
Is used for many purposes, such as securing the collars in clothing a bowsprit, and strops in rigging a lower or topsail-yard. In fact, all collars and block -strops, fitted with lashing-eyes, such as bobstay and bowsprit shroud-collars, jeer-blocks, truss-strops, topsail sheet-blocks, clew garnet-blocks, quarter-blocks for topsail yards, &c., when not fitted with tails.
NOTE.-Clew garnet-blocks are fitted at Portsmouth Yard with a pendant spliced in one end, and an eye in the other ; the length of pendant is once and a third the round of yard, the pendant is passed from forward aft, under the jackstay, round the yard, and seized to the jackstay, then a small strop is placed over the block, and brought up abaft the yard, and seized to jackstay, for steadying the block.
A rose-lashing can be passed either with one end or two.
To pass a rose-lashing on one end, splice the other end into the eye of the strop or collar you are going to lash, then pass either from right to left, or left to right, passing it over the eye on one side and under on the other, until sufficient number of turns are passed to bear the strain equal to the collar or strop being lashed, which is generally about seven turns ; then the end is passed between the crossing turns twice, and dipped up through as near the centre of the seizing as possible, and is finished off by crowning and walling the end close to the crossing turns.
To Pass a Rose Lashing on both Ends of a Lashing.
The lashing is middled in the centre of one of the eyes ; the eyes are then passed, one under, and one over the eyes ; for instance, the end that goes over the right-hand eye goes under the left-hand eye, until sufficient number of turns arc passed ; the ends are then dipped, in opposite ways, through the crossing, each end twice each way ; both ends are finished off, as before, being crowned first, and walled after.
A Cross Seizing
Is used when the rigging is turned in with the end up ; it is simply a round seizing, but instead of being finished off with a round turn round all parts, and a clove-hitch, after the riding terns are passed, the end is merely dipped down between the lower and upper turns, and. the end is expended round the standing part of the shroud, and secured with a yarn.
