AN IMPROVED HOOK FASTENER
Year: 1884

page_text: I, JAMES M'KENNY, of Stephen's Green, Dublin, M.R.C.V.S. do hereby declare
the nature of the said invention for AN IMPROVED HOOK FASTENER, to be as
follows:-
This invention relates to an improved hook fastener for horses' and dogs' chains,
and carriage pole chains, and is also applicable for fastening chains and ropes used
in the rigging of vessels, and for other purposes, in a perfectly secure, simple, and
durable manner.
My invention consists in the formation of a hook similar in appearance, but
different in construction, to an ordinary swivel-hook. The hook and finger used in
iny invention are provided with legs or arms at the extremities of which eyes are
pierced, and through these eyes is passed an elongated link by means of which the
hook is kept closed or opened at pleasure. Thus so long as the elongated link is in
a line with the legs or arms, the extremities of said legs or arms will lie in the
narrow angle of the link, and, not being capable of separating while in this position,
the hook cannot, consequently, open. In order to open the hook the elongated link
must be brought to a position at right angles to the legs or arms, when the said
legs or arms, no longer being confined in the narrow angle of the link, can now be
separated, and the hook thereby opened by this double action ((1) bringing the
link to the right-angle position, and (2) separating the legs).
-
This arrangement enables me to dispense with the spring ordinarily used in
swivel hooks for the purpose of keeping the same closed.

page_text: I, JAMES MCKENNY, of Stephen's Green, Dublin, M.R.C.V.S., do hereby declare
the nature of my invention-for- AN IMPROVED HOOK FASTENER and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This Invention relates to an improved hook fastener for horses and dogs' chains
and carriage-pole chains, and is also applicable for fastening chains and ropes used
in the rigging of vessels, and for other purposes.
My invention consists in the formation of a hook, similar in appearance, but
different in construction to an ordinary swivel hook. The hook and fingers used
in my invention are provided with legs or arms, at the extremities of which eyes
are pierced, and through these eyes is passed an elongated link, by means of which
the hook is kept closed or opened at pleasure. Thus, so long as the elongated
link is in a line with the legs or arms, the extremities of said legs or arms will lie
in the narrow angle of the link; and, not being capable of separating while in this
.position, the hook cannot, consequently, open. In order to open the hook, the
.elongated link must be brought to a position at right angles to the legs or arms;
when the said, legs or. arms, no longer being confined in the narrow angle of the
link, can now be separated, and the hook thereby opened by this double action
(ie. (1) bringing the link to the right-angled position, and (2) separating the
legs).
This arrangement.enables me to dispense with the spring ordinarily used in
swivel hooks, for the purpose of keeping same closed.
The accompanying drawing will enable my said Invention to be more readily
understood and applied in practice :-Fig. 1 shows the hook closed, and fig, 2 shows
'same open. It will be obvious that so long as the extremities of the hook lie in
the narrow end of the elongated link, as shown in fig. 1, the hook cannot open;
while immediately the link is brought to the position seen in fig.2 the book will
readily open.
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
The use and application of a hook fastener for the purpose and in the manner
substantially as herein described and set forth.
