PROVISIONAL SPECIFICATION.
Improvements in Hook and Eye or Open Clasps.
I, EMILE HOUTAIN, of 54, Rue des Commerçants, Brussels, in the Kingdom of
Belgium, do hereby declare the nature of this invention to be as follows:-
This invention which I term the Eagle clasp consists in providing either the hook
or eye with an inner projecting curved portion the size of which is so proportioned
that the eye can neither be passed onto, nor slipped off, the hook without the
employment of force. To obtain this result it is necessary that the free space or
opening should be somewhat smaller than the thickness of the eye.
Metal clasps of any size or description may readily be fitted with this improve-
ment by a suitable stamping process or the like.
Metal clasps provided with this automatic fastening device may be hooks and
loops made of wire or such as are stamped out of sheet metal etc. or the like.

In the drawing
Figure 1 is a plan of a hook and eye in which A designates the portion of the
hook whereby it is attached to the material; B the hook proper, and C the eye
passed over it.
Figure 2 is a section through a-a Figure 1, showing the curved portion of the
body of the hook in one form, A is a perspective view of the portion A Fig. 1;
B is the hook proper, C the portion of the eye, D the curved part of the shank of
the hook partly obstructing the space E through which the eye C has to move and
adapted to oppose a slight resistance to the latter both when it is passed onto or
taken off the hook. E is the space provided between the hook and the shank for
the reception of the eye.
Fig. 3 is a section on the line a a of Fig. 1 showing the curved portion of another
form of hook. A is the portion corresponding to A. Figure 2, B is the hook proper,
Ca portion of the eye indicating its thickness. D is the curved portion of the
hook (see B Fig. 2) and E the part corresponding to E Figure 2.
Figure 4 is a section on line a-a Figure 1 showing a form of hook in which both
the shank and the bent extremity forming the hook proper are provided with

page_text: projecting curves. A is the part corresponding to A Figure 2, B is the hook
proper, a portion of the eye indicating its thickness, D the curves or bends formed
both in the shank of the hook and in the hook proper (see D Figure 2). E corre-
sponds to E Figure 2.
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 :-
A hook such as A B having a curve or bend such as D in one or both of the
parts A and B substantially as described and illustrated in the accompanying
drawings.
