PROVISIONAL SPECIFICATION.
An Improved Sail Hank.
ALFRED CHARLES EMBLING 65 Avenue Road Gosport Mariner do hereby
declare the nature of this invention to be as follows:-
The sail hank is on the travelling band principle. The part attached to the sail
by a lashing through the two holes travels round a band fitted with a top and
bottom collar, and has a projection which stops against a bridge over this part
across from the two collars to make the opening in this travelling part readily
coincide with the opening in the band. It is then hanked over the stay to which
the sail is to be attached and the travelling band slipped round to close the
opening.

COMPLETE SPECIFICATION.
An Improved Sail Hank.
I, ALFRED CHARLES EMBLING of 65, Avenue Road, Gosport in the County
of Hants, Mariner, 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 :—
3
This invention relates to sail hanks or the loops or rings to which the
weather-leech of a fore-and-aft sail is bent, and by which it slides on the mast
in hoisting by the halyards or lowering by the downhauls, or by which the head
of a spanker is sometimes bent to the gaff, or the head of a stay-sail to the stay.
My said invention consists in making the said hank of two primary parts, one
a fixed and gapped ring, and the other a rotatory-travelling one for the closing
of the gap, which when open, admits of the hank, which is attached by lashings
to the leech of a sail being hanked onto the stay or mast to which the said
sail is bent.
Figure 1 of the accompanying drawing represents in front elevation a sail-hank
constructed, arranged and fitted or provided with improvements according to my
invention showing the gap closed by the travelling closure ring.
Figure 2 represents an edge view of the same.
Figure 3 represents a transverse vertical section of the said hank on the dotted
lines A B Figure 1. This said view shows the disposition of the travelling or
movable part relative to the fixed body part.
Figure 4 represents front and edge views of the hank, but with the travelling
closure ring turned round so as to open the gap.
Figure 5 represents a back elevation of Figure 1.
Figure 6 represents a vertical section of the hank upon the dotted lines C D
Figure 2.
Figure 7 represents a front elevation of the body of the bank separately,
Figure 8 is an edge view of the same,
Figure 9 is an edge view of the gapped and travelling closure ring and Figure 10
is an edge view thereof.
Figure 11 represents my invention applied for bending the leech of a fore-and
aft sail to a mast.

page_text: Figure 12 represents my invention applied to bending a stay sail to stay.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a is a ring-shaped frame or body part, with a gap or opening a¹, made through
one of its sides a³, having terminations a³, a', so that between the said points a³, a',
the gap a¹, intervenes. a is the shank part, having holes or piercings a', where-
through the lashings for attaching the hank to the sail pass, whilst working within
a hole a', made transversely through the said shank is a loosely fitted bridge-stop c,
consisting essentially of a double headed pin, which forms a stop for both limiting
the motion of, and locking in position, the gapped and travelling closure band or
part ring b, having an opening or gap b', through its sides, and fitted to work
within the inner circumference a, of the ring body part a. This said travelling
closure band b, has a shoulder stop 6, for limiting its movement relative to the
gap a', that is to say the stop prevents the gap b', of the travelling closure band b,
from overlapping the gap a', of the body frame a, when the bridge stop c, is in one
position. The travelling closure ring is channelled upon its outer periphery b' so
as to form sides, which act as guides for keeping it in position within the body
of the hank.
The bridge stop consists of a loose pin c, having a long shank c², and head
ends c, c. The head c', when in the position as in Figure 4 keeps the gap b',.
coincident with the gap a', whilst the bead c, when in the position as in Figure 2
(which it takes by gravity when the hank is upon its side as shown) forms a lock
to the travelling band by the said head or stop part coming within the path of the
termination or end, of the travelling band b.
Thus assuming that the hank is closed as in Figures 1 and 2 and that the same
is being used for bending a fore and aft sail to a mast, then the loose bridge falls
by gravity into the position as in Figure 2 and locks the travelling closure band in
its gap-closing position so that the same cannot fully rotate as its ends cannot pass
the said bridge until the same has been lifted, as the said bridge lies within the
path of the end. Now assuming that the bridge has been lifted and the head
end c', has become clear of the end of the band b, then the said band can be
rotated and its gap b', brought coincident with the gap a¹.
By the reciprocal action of the bridge, the said band is prevented from being
rotated further than will allow both gaps to coincide as in Figures 1 and 2, and
the stop action is accomplished by the head c coming within the path of the
stop b².
Instead of the closure band rotating upon the inner periphery of the body, it
may be made to rotate upon the outer periphery thereof with like effect.
It is understood that when the hank is open it is then-hanked over the mast
or stay to which a sail is to be attached and then the solid part of the travelling
or part rotating band is brought round opposite the gap in the body part, which
is thereby closed.
Instead of operating the bridge stop by hand or by gravity, it may be made
automatic by an interposed spring disposed between or around the shank and
between the head c, and the shank as, of the body ring a. In this form of hank
the locking is made absolute even when applied to stays or gaffs.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. A sail hank composed of two ring-like component parts having gapped
sides and with the one part adapted to travel or turn within the other or upon the
other so as to either bring the gapped part of the one coincident with the gapped
part of the other, or the solid part of the one coincident with the gapped part
of the other, substantially as and for the purpose as herein described and set
forth.
Secondly. In a sail hank, the combination with the component parts of a sail

page_text: bank of the construction referred to in the previous claim, of a bridge stop c, with
shank c', and heads or their equivalents c, c, which act alternately as blocks for
the locking of the movable band part both in its closing position and in its opening
position, substantially as described and set forth.
Thirdly. The improvements in sail hanks, and the general construction,
arrangement and combination of the parts substantially as and for the purpose
as described and set forth in the several figures of the drawing.
