Complete Specification Accepted, 1st June, 1889
I, GEORGE FROST of 23 Denman Street, Haymarket in the County of Middlesex,
Mariner do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a shackle the pin of which can be
easily withdrawn and which will not rust together as is the case with those at
present in use.
According to this invention I form the eyes of the shackle into slot holes
and the pin I make with the middle portion deeper than the ends which fit into
the slots.
The pin is passed through the eyes and retained in position by means of wooden
cotters passing transversely through the eyes. To release the pin all that is necessary
is to break or cut away the cotters when the pin may be driven out easily the only
tools required boing a knife and marlinspike.

page_text: I, GEORGE FROST of 23 Denman Street, Haymarket in the County of Middlesex,
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 :-
The object of my invention is to provide a shackle which when fastened shall be
perfectly secure, and the pin of which may when desired be easily withdrawn,
without the aid of special tools other than those in constant use by seamen, and also
the-pin of the said shackle shall be so constructed and arranged as not to-become-
rusted in and fixed.
According to my invention I form the eyes of the shackle elongated and the pin
I make with the middle portion deeper than the ends fitting into the elongated eyes.
The pin or bar is passed through or into the eye or eyes and retained in position by
means of wooden cotters passing transversely through the said eyes.
The accompanying drawings fully illustrate the manner in which I carry my
invention into effect. Figure 1 is a side elevation partly in section and Figure 2 an
end view of a shackle constructed according to my invention where the pin is made
separately and detached from the shackle proper; Figure 3 shews the application of
the invention where the pin is linked to the shackle instead of being separate
therefrom. A A shew the shackle eyes, B the pin, and CC are the wood or other
soft material forming cotters for passing through the transversely cut eyes.
These
transverse eyes are made preferably of V shape as shewn, in order to facilitate the
removal of the cotters CC from the said eyes when it is required to take out the pin,
and this can be easily accomplished by a knife which a sailor for example always has
or ought to have ready at hand, or it could be knocked out by a marlinspike or other
tool. The wood cotter takes the place of the ordinary mousing and is much more
secure.
Shackles constructed according to my invention may be used as a hook for blocks
and other gear where a secure fastening is required, but which can be at the same
time unfastened with facility.
The pin can always be removed no matter how rusty the shackle may be, because
by taking out or cutting away the wood cotter C, the pin B may be knocked up into
the upper and larger part of the slot and may then be drawn out without trouble. If
there should be stumps of the wooden cotters Cleft in the holes, they (the stumps)
may be knocked down into the larger part of their slots and drawn out.
The shackles can be made of any required shape as the pin has only to be adapted
to suit the shape of the shackle to which it is to be applied. Great strength and
neatness are obtained, and when applied as a hook there is no leverage but only
tension strain.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. In shackles, forming the eyes A A thereof with transverse eyes or holes to
receive wood or other cotters C for securing the pin B substantially as and
for the purposes hereinbefore described with reference to the accompanying
drawings.
2. In shackles the combination of the pin or bar B, the elongated tapered eyes A,
for receiving the similarly shaped ends of the pin or bar B and formed with the
transverse tapered eyes for receiving the cotter C substantially as set forth.
Dated this 30th day of April 1889.
