smith, and JOHN ABRAHAM, of 3, Shooter's Hill, Cowes, Isle of Wight, Outfitter,
do hereby declare the nature of this invention to be as follows:-
Our invention relates to shackles, and consists of the improvements herein
described by means of which the pin of shackles, made according to our inven-
tion, can be very readily, simply, and securely fixed in the closed position, and
as readily opened out at will, so that the shackle can be almost instantly and
securely connected to, say an eyebolt, ring, or similar closed fitting, and as readily
disconnected from same.
In making a shackle according to our said invention a vertical central recess
is formed in one arm of the shackle, lengthways of same, and in the lower part
of this recess a coil spring is fitted, and on the top of same in the recess a bolt,
arranged to project somewhat above the lower side of the eye of shackle when it
(the bolt) is in its normal position, and to move up and down in the recess.
At the underside of the shackle pin a hole is formed of a size and shape adapted
to take the projecting top part or point of the aforesaid bolt.
The shackle pin is made, and fitted in the shackle in the following manner,
on the upper part of the pin a narrow groove is formed extending to within a
short distance of the ends of the pin.
The pin is inserted in the shackle at the eye in the opposite arm to that in
which the aforesaid sliding bolt is fitted, and a screw stud is fitted in the top of
this eye arranged to be screwed down from the top until the point of stud is in
engagement with the aforesaid groove in the shackle pin, but the groove will be
large enough to allow of the free in and out movement of the pin, in the shackle
eyes, to an extent only limited by the length of the groove, that is, the pin can be
withdrawn from the shackle until the inner end of the groove butts against the
point of the screw stud, the shackle pin will then be withdrawn so as to leave the
opening in the clear at the inside of shackle quite free, but the point of shackle
pin will be housed and retained in the eye of the shackle; by this arrangement the
in cannot be mislaid or lost being always in engagement with the shackle, but
hould it be desired for any reason to entirely disengage the pin from the shaekle
t is only necessary to unscrew the aforesaid screw stud for the purpose.
When engaging the shackle the pin is first withdrawn to the desired extent,
nd after the shackle is engaged the pin is pushed forward in the usual manner,
neanwhile the sliding bolt is depressed, when the end of the pin passes over same,
his being readily effected by reason of the point of the pin at the underside being
mewhat curved upwards, but directly the pin is pushed home the bolt shoots
to the hole at the underside of the point of the shackle pin, by reason of the
e-action of the spring, and the bolt thereby locks the pin in the engaged posi-
on in which it remains until unlocked in manner hereinafter described

slot is formed into which a small pin is passed the point of which is screwed
into the sliding bolt, the slot is of sufficient length to allow of the necessary free
up and down travel of the spring bolt for the above specified purpose.
A shallow recess is also formed in the face of shackle of sufficient width and
depth to take and house the head of the aforesaid bolt pin, so that it is flush with
the outside of the shackle, this recess extends above the top of the pin head so as
to admit of the insertion of a finger end, or the equivalent for same, for the purpose
of pressing the bolt down when it is desired to release the shackle pin.
The shackle pin can be made so that the head and point of same are flush with
the outside of shackle, or if preferred with a projecting eye or ring on the head
of pin.
Our improvements are applicable to most if not all fittings commonly known as
shackles, made of any kind of metal or combinations of same.

Improvements in Shackles.
We, ALBERT EDWARD LINE, of 16, Shooter's Hill, Cowes, Isle of Wight, Black-
smith, and JoHN ABRAHAM, of 3, Shooter's Hill, Cowes, Isle of Wight, Outfitter,
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:-
-
Our invention relates to shackles, and consists of the improvements, hereinafter
described, by means of which the pin of shackles, made according to our inven-
tion, can be very readily, simply, and securely fixed in the closed position, and as
readily opened out at will, so that the shackle can be almost instantly and securely
connected to say an eyebolt, ring, or similar closed fitting, and as readily dis-
connected from same.
In the accompanying drawings we have shewn what we consider to be the best
means of carrying out our improvements, in which: --
Fig. 1, is a central sectional elevation of a shackle made according to our
invention.
Fig. 2, an end view on the face A of the shackle.
Fig. 3, an end view on the face B of the shackle.
Fig. 4, a complete plan on top of shackle.
Fig. 5, a sectional plan taken on the line a, a.
Like letters indicate corresponding parts throughout the drawings.
In making a shackle according to our said invention a vertical central recess C
is formed in one arm of the shackle, lengthways of same; and in the lower part of
the recess a coil spring D is fitted, and on the top of same in the recess a holt E,
arranged to project somewhat above the lower side of the pinhole, when it (the
bolt) is in its normal position, and to move up and down in the recess riding on the
spring I

page_text: At the underside of the shackle pin F a hole G is formed of a size and shape
adapted to take the projecting top part or point of the bolt E.
The shackle pin F is made, and fitted in the shackle in the following manner;
on the upper part of the pin a narrow groove H is formed extending to within a
short distance of the ends of the pin.
The shackle pin is inserted at the eye in the opposite arm to that in which the
sliding bolt E is fitted and a screw stud J is fitted in the top of this eye arranged
to be screwed down from the top until the point of the stud is in engagement with
the groove H, but the groove will be large enough to allow of the free in and out
movement of the shackle pin in the shackle eyes to an extent only limited by the
length of the groove, that is, the pin can be withdrawn from the shackle until the
inner end of the groove abuts against the point of the stud J, the shackle pin
will then be withdrawn so as to leave the opening in the clear, between the shackle
eyes, quite free, but the point of shackle pin will be housed and retained in, one eye
of the shackle.
By this arrangement the shackle pin cannot be mislaid or lost, being always
in engagement with the shackle, but should it be desired for any reason to entirely
disengage the pin from the shackle it is only necessary to unscrew the stud J for
the purpose.
In the face of the shackle arm in which the sliding bolt E is fitted, a vertical
slot K is formed into which a small pin L is passed the point of which is screwed
into the sliding bolt E, the slot is of sufficient length to allow of the necessary
free up and down travel of the spring bolt E.
A shallow recess M is also formed in the face of the shackle of sufficient width
and depth to take, and house the head of the pin L so that it is flush with the out-
side of the shackle. this recess extends above the top of the pin head so as to admit
of the insertion of a finger end, or the equivalent for same, for the purpose of
pressing the bolt down when it is desired to release the shackle pin.
The stud J in engagement with the groove H also serves to prevent the shackle
pin from rotating in the eyes of shackle.
When engaging the shackle the pin is withdrawn to the desired extent, the bolt E
being first depressed, by means and in manner hereinbefore described, thereby
releasing the pin: after the shackle is engaged the pin is pushed home whereby
the sliding bolt E and spring D is depressed as the end of the pin passes over same.
this being readily effected by reason of the point of the pin being somewhat curved
unwards at the underside, but directly the pin is pushed home the bolt E shoots
into the hole G, at the underside of the point of the shackle pin, by reason of the
re-action of the spring, and the bolt E thereby locks the shackle pin in the
engaged position in which it remains until unlocked in manner aforesaid. The
shackle pin can be made so that the head and point of same are flush with the out-
side of shackle, or if preferred with a projecting eye, ring, or head.
We can if preferred plug the hole N after forming the recess C in shackle,
such hole being made during the operation of boring or otherwise forming the
said recess, and after this is done it will not be required.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what we
claim is:-
1st. The improved shackle consisting of the parts all-constructed and combined
substantially as described with reference to the accompanying drawings and oper-
ating as and for the purposes as herein specified.
2nd The construction of a shackle, of the herein described type, with a spring
locking bolt for the shackle pin and other devices substantially as herein described
with reference to the accompanying drawings for the purposes herein specified.
3rd. In combination, the shackle having a pin F with a groove H in same, a
stud in one arm of the shackle engaging with the said groove so as to retain the

page_text: pin in the shackle, a spring bolt E in the opposite arm adapted to lock the shackle
pin in the shackle, and means and devices for unlocking same, all substantially
as herein descried for the purposes specified.
4th. The herein described method of, and means for locking and unlocking the
pin of a shackle substantially as herein described.
