An Improved Studded Connecting Shackle for Chains and Chain Cables.
We, HENRY WARRINGTON and HENRY JAMES WARRINGTON, trading together as
Henry Warrington & Son, of Berry Hill Works, Stoke-on-Trent, in the County
of Stafford, Coal and Iron Masters, do hereby declare the nature of this invention
to be as follows:-
This invention consists of the herein described improved studded connecting
shackle for chain cables and for other chains such as crane chains, steering
chains, and others. Our improved connecting shackle possesses all the advan-
tages of the various connecting shackles now in use and at the same time is so
constructed as to dispense with the use of enlarged or end links. By our inven
tion chain cables and other chains can readily be connected at any part without
the usual accessory of enlarged or end links and moreover our shackle is so con-
structed as to permit of its working freely round a capstan or wheel without
the danger of its riding or slipping. As we are enabled to dispense with the
enlarged or end links which are usually attached to chain cables and other chains
the weight of the ship's chain cables and chains will be considerably reduced
thereby materially assisting in adding to the speed of the vessels carrying chain
cables and chains fitted with our improved connecting shackle.
One part of our improved connecting shackle has somewhat the appearance of
the letter H which is made just wide enough between the limbs to admit the
links of the chain or chain cable which are to be connected together. Each
of the four projecting limbs of this H shaped part is formed as an eye preferably
of an oval form and in these eyes two cross bolts or pins are fitted which pass
through the links of the two pieces of chain or chain cable which are thus con-
nected together. These two bolts or pins are arranged at just the proper dis-
tance apart as to give the proper pitch to the two links which they connect
together. The cross pins or bolts are secured in place by any convenient means
as by taper pegs which are driven through the limbs of the H shaped part and
through the cross pins and there secured by lead washers in recesses at the larger
ends of the taper pegs.
In the event of a chain cable or other chain parting at any place it can
immediately be re-connected and made ready for work again by inserting the
two links of the parts of the chain or chain cable between the limbs of the H shaped
part and then passing the bolts through the eyes and securing the bolts by the
taper pegs or other convenient means as above described.
By the H shaped part of the shackle being fitted or made with a solid forged
stud or distance piece as its centre it is thereby materially increased in strength
in addition to which the said stud prevents the sides of the shackle from collapsing
under strain and also acts like a buffer between the ends of the links which are
connected to the shackle thereby preventing them from becoming locked or wedged
one with the other when the chain cable or chain is at work.

steel.

An Improved Studded Connecting Shackle for Chains and Chain Cables.
We, HENRY WARRINGTON and HENRY JAMES WARRINGTON, trading together as
Henry Warrington & Son, of Berry Hill Works, Stoke-on-Trent, in the County
of Stafford, Coal and Iron Masters, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
This invention consists of the herein described improved studded connecting
shackle for chain cables and for other chains such as crane chains, steering
chains, and others. Our improved connecting shackle possesses all the advan-
tages of the various connecting shackles now in use and at the same time is so
constructed as to dispense with the use of enlarged or end links. By our inven
tion chain cables and other chains can readily be connected at any part without
the usual accessory of enlarged or end links and moreover our shackle is so con-
structed as to permit of its moving freely round a capstan or wheel without
the danger of its riding or slipping. As we are enabled to dispense with the
enlarged or end links which are usually attached to chain cables and other chains
the weight of the ship's chain cables and chains will be considerably reduced
thereby materially assisting in adding to the speed of the vessels carrying chain
cables and chains fitted with our improved shackle.
We will describe our invention by referring to the accompanying drawing
on which Fig. 1 is a front view and Fig. 2 is a side view of a studded connecting
shackle constructed according to this invention illustrated as connecting together
two links of a chain cable; Fig. 3 is a plan of the same and Fig. 4 shews
separately one of the cross bolts of the connecting shackle.
The same letters of reference indicate the same parts in all the figures.
The principal part marked A of our improved connecting shackle has some-
what the appearance of the letter H (see Fig. 1) which is just made wide
enough between the limbs a¹ a² and a³ a to admit the links B 132 of the chain
or chain cable which are to be connected together. Each of the four projecting
limbs a¹ and a3 a4 of this H shaped part A is formed as an eye (see Fig. 2) prefer-
ably of an oval form and in these eyes two cross bolts or pins C₁ Care fitted
which pass respectively through the links B 12 of the two pieces of chain or
chain cable which are thus connected together. These two bolts or pins C C
are arranged at just the proper distance apart so as to give the proper pitch to
the two links B B which they connect together. The cross bolts or pins CC
are secured in place by any convenient means as by being made with a small
counter-sunk head e¹ at one end and by a taper peg d at the other end which peg
is driven through a corresponding hole in the limb of the H shaped part and there
secured as by a lead washer e (see Fig. 2) fixed in the recess f at the larger end
of the taper peg d.
In the event of a chain cable or other chain parting in any place it can
immediately be reconnected and made ready for work again by inserting the
links B B of the pieces of the chain or chain cable between the limbs a¹ a

page_text: and a at of the H shaped part A as shewn on the drawing and then passing
the bolts through eyes of the H shaped part and through the links B¹ 12
and securing the bolts C C to the H shaped part A by the taper pegs d or by
other convenient means as above described.
By the H shaped part A of the shackle being fitted or made with a solid forged
stud or distance piece a as its centre it is thereby materially increased in strength
in addition to which the said stud prevents the sides of the shackle from
collapsing under strain and also acts like a buffer between the ends of the links
B2 B3 which are connected to the shackle thereby preventing them from becoming
locked or wedged one with the other when the chain cable or chain is at work.
The H shaped part A of the shackle can either be stamped or forged from
iron or steel.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
The improved studded connecting shackle for chains and chain cables consisting
of the H shaped part A and cross pins C C constructed and combined together
in the manner substantially as herein set forth and illustrated.
