Tackle
TACKLE. - The number of parts of the
fall of a tackle is more or less, in proportion to the effects intended to be
produced. That part of the fall which is fastened to one of the blocks is called
the standing part, and the other parts of it are called the running part. (PI.
7, figs. 2 and 3). Tackles are used to stretch the rigging in the house,
&c., to raise or remove weighty bodies, to support the masts, extend the
rigging, or expand the sails. They are either moveable, as connecting with a
runner, or have one part fixed to an immoveable station by a hook, lashing,
&c. A tackle is a convenient kind of purchase, but subject to much friction.
I~s power will be (the friction not considered) as the number of the parts of
the fall that are applied to sustain the weight. If a tackle consists of a
double and a single block, as pI. 7, fig. 3, and the weight to be hoisted is 'huFlg
to the single block, there will be four parts of the fall; and the weight
resting upon four ropes equally stretched, each must,bear the same part of the
weight. Thus, suppose the weight -hung to the single block be 4 cwt., then I
cwt. applied to the hauling .part of the fall will suspend it; and, if as
IJ;ludh more power be applied as will overcome the friction, it will purchase
the weight; but had the weight been hooked to the double block, it would have
rested on three ropes only, each, of which would bear one-third of the weight;
therefore one:.third of the weight being applied to the

hoisting part of the fall, would suspend the weight when hooked to the double
blocks; and as much more power being applied as will overcome the friction,
would purchase the weight. Ropes, if tight laid, will not easily bend round
small sheaves, but will take up a considerable part of the power to force them
into their proper direction; hence it follows, that blocks with small pins,
large sheaves, and slack-laid ropes, are the best materials to obviate friction
and make tackles with. The blocks that are fixed, commonly called
leading-blocks, are only for the conven- ience of turning the direction of the
fall; they add nothing to the power of the purchase, but, on the contrary,
destroy so much as is necessary to overcome their friction, and are therefore to
be avoided as mllch ,as possible. It may be here remarked, that the blocks of
all the standing and running rigging are generally strapped and p"repared
in the house.
The.Anchor-stock Tackle is composed of a double block and a single block,
strapped with a hook and thimble. Boom Tackles are composed of double and
single blocks, strapped with tails. Bowline Tackle is composed of a long
tackle and a single block, strapped with a hook and thimble. Burton Tackles are
com- posed of double and single blocks, and are used with pendants. A Fish
Tackle is composed of a long tackle and a single block, strapped with eyes,
and is used with a pendant. (PI. 6, fig. 4). Jigger Tackles are composed
of double and single blocks, strapped with tails. A Long Tackle is
composed of two blocks, - a long tackle-block, and a common single-hook block.
The long-tackle block is double, but it resembles two single blocks, joined
together at their ends. (PI. 7, fig. 3). Luff Tackles are composed of
double and single blocks, strapped with a hook and thimble. Outhauler Tackle is
composed of two single blocks, strapped with tails. Quarter Tackles are
composed of a double block, strapped with eyes, and a single block with a hook
and thimble, having a long strap. Reef Tackles (PI. 13, figs. 22 and 33)
are composed of two single blocks; one block has a thimble seized to it, which
the reef tackle is rove through, and the other is strapped with an eye round the
top-sail yard-arm, if the sister block is not used. Relieving Tackles are
the same as luff tackles. . Ridge Tackle is composed of a double block
and single block, strapped with an eye. Rolling Tackles are the same as
luff tackles. Rudder Tackles are composed of long tackle blocks
59
and single blocks, strapped with hooks and thimbles. Runner Tackles are
composed of double and single blocks and a pend- ant; the lower blocks are
strapped with a hook and thimble. Stay Tackles, main and fore, are
composed of double and single blocks: the double blocks are spliced into a
pendant; the single blocks have a long strap, like pL 9, figs. 48, 49,50. The
pendants have. a span from the fore to the main. Stay-sail stay Tackles are
composed of double and single blocks; the lower blocks are strapped, with a hook
and thimble. Pre venter Backstay Tackles are composed of double and
single blocks, strapped with a hook and thimble, except they are fitted with
runners. Tack Tackle is composed of a double 1\nd single block, strapped
with hooks.
and thimbles. The Top Tackle is composed of double and treble
blocks" (PI. 9, figs. 15 and 16). It is strapped with hook and thimble, and
hooks to the top-rope pendant; generally iron- bound. Truss Tackles are
composed of one single or double block, strapped jn the truss pendant. Winding
Tackle is com- posed of a fDur-fold and a treble block, or a treble and a
double block, strapped with eyes, and toggles to the winding tackle pendant.
(PI. 2, fig. 21) . Yard Tackles are composed of dou- ble and single
blocks; the double blocks are spliced into the lower ends of pendants, and the
single blocks are strapped with hooks and thimbles. (PI. 10, figs. 5 and 6).
