PROVISIONAL SPECIFICATION.
An Improved Safety Hook.
I, PATRICK FITZGERALD, of 15 Charleville Terrace, North Circular Road,
County Dublin, Ireland, Gentleman, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved safety hook for use in all cases where a
simple, convenient and effectual fastener, or connecting link may be required.
In carrying out my invention I form a hook of flat metal composed of two parts,
one part being stationary, and the other part movable on a pivot, so as to swing
laterally in opening and closing the hook. The base of the stationary part is
provided with an eve, and the base of the movable part with a cut or slot expanding
from the edge inwards, which when the two parts are in their normal position
coincides with the eye in the stationary part while its free end overlaps the free
end of the stationary part and closes the hook in the manner presently described.
An ordinary ring of suitable size and strength, and provided with a transverse
cut or notch across its section is then passed through the eye of the stationary
part, and the cut or slot in the movable part and closed up.
As thus coupled up the hook cannot be separated from the ring, nor can the hook
be opened. In order to open the hook it is necessary to draw its base round to a
position coincident with the transverse cut or notch in the ring when the movable
arm of hook can be readily moved laterally, and the hook thus opened.
It is obvious that to open or close the hook, its base must be brought into the
position on the ring just described so as to allow the cut or slot in the movable arm
to swing laterally.

COMPLETE SPECIFICATION.
An Improved Safety Hook.
I, PATRICK FITZGERALD, of 15 Charleville Terrace, North Circular Road,
County Dublin, Ireland, Gentleman, do hereby declare the nature of this inven-
tion 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 safety hook for use in all cases where a
simple, convenient and effectual fastener, or connecting link may be required.
In carrying out my invention I form a hook of metal composed of two parts, one
part being stationary, and the other part movable on a pivot so as to swing laterally
in opening and closing the hook. The base of the stationary part is provided with
an eye, and the base of the movable part with a cut or slot expanding from the
edge inwards, and which, when the two parts are in their normal position coincides
with the eye in the stationary part, while its free end overlaps the free end of the
stationary part, and closes the hook in the manner presently described.
An ordinary ring of suitable size and strength, and provided with a transverse
cut or notch across its section, or a portion of its section squared, is then passed
through the eye of the stationary part of the hook, and also through the cut or slot
in the movable part and is then closed up.
As thus coupled the hook cannot be separated from the ring, nor can the hook be
opened.

page_text: In order to open the hook it is necessary to draw its base round to a position
coincident with the transverse cut or notch, or the squared section in the ring when
the movable arm of hook can be readily moved laterally and the hook thus opened.
It is obvious that to open or close the hook, its base must be brought into the
particular position on the ring just described, so as to allow the cut or slot in the
movable arm to swing laterally.
The accompanying drawings will enable my said invention to be more readily
understood.
Fig. 1, is a plan of the hook and ring complete, showing the hook closed; and
Fig. 2, a side view of same showing the hook open.
The squared section of the ring is shown at a,b, is the stationary part of the
hook, and c, the movable arm swinging on the pivot d.
So long as the hook plays on the round section of the ring, it cannot be opened
since the expanding slot in movable arm partly embraces same, but immediately
the hook is brought to a position in the squared section of the ring, the movable
arm may be tilted laterally as shown in Fig. 2, and the hook thus opened.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I would have it
understood that what I claim is.
A fastening hook or connecting link consisting of a ring with a portion of its
section notched or squared, and a hook composed of a stationary and a movable
arm, constructed and operated in the manner substantially as herein described and
set forth.
Dated the 19th day of July 1893.
