PROVISIONAL SPECIFICATION.
Improvements in Hooks and Eyes.
I, HEINRICH MENTZEL, of 60 Sebastian Strasse, Berlin, in the Kingdom of
Prussia, German Empire, Ladies' Dress-maker, do hereby declare the nature of my
said invention, to be as follows :-
My invention relates to a clasp for dresses and consists of an eye of usual
construction, which is combined with a hook of an improved construction. My
invention therefore consists in making the hook with an elastic arm and providing
this arm with a nose which will permit of the easy introduction of the eye, but will
not allow the latter to slip out of the hook spontaneously.
My invention will be more readily understood by reference to the accompanying
drawings, in which:
Fig. 1 is a side elevation of my improved hook.
Fig. 2 a plan of the same.
Fig. 3 shows the clasp in locked position.
Fig. 4 is a side elevation of my improved hook, the elastic arm being shown in
its depressed position, so as to release the eye.
Similar letters refer to similar parts throughout the several views.
In carrying my invention into effect, I construct the hook of the clasp as
illustrated by Figs. 1 & 2, that is to say, I form the hook of one piece of sheet-
metal, which is left plane in its main part a, and bent upwards and backwards at one
of its ends, so as to form a tongue, as shown at b. care the usual eyes or holes at
which the stitches are made for securing the hook to the fabric. The middle
portion of a b is cut by two longitudinal incisions, extending nearly from end to
end in such a manner that the narrow central stripe d connects only with the main
part a of the hook, as will be seen at e, and is entirely separated from the hook at
all other points. The stripe d is bent hereafter into the shape shown at Fig. 1, so
as to form an elastic arm provided with a nose f opposite the end of tongue b, and
protruding with its end somewhat beyond the bend between a and b, as shown at g.
The protruding end portion of the elastic arm d need not be straight as shown, but
may be bent to any shape desired. In Fig. 3 h designates the eye constituting the
second element of the clasp; this eye is of the usual construction, as already
mentioned.
The operation of my invention will be easily understood. When the eye his
inserted between the nose and the end of the tongue 6 and pulled towards the
right in Figs. 1 and 3, the arm d will yield on account of its elasticity and will be
depressed as much as is necessary for allowing the passage of the eye h into the
space between the nose and the bend of the hook a b. The eye h will then be
securely locked, and it will be obvious that any attempt to force the eye / out of
the space in which it is confined will only result in pressing the nosef of the elastic
arm d upwards so as to close entirely the passage between tongue 6 and nose f.
When wishing to withdraw the eye h from the hook a b, the protruding end g of
the elastic arm d is depressed with the finger, so that the main part of said arm is
brought in the plane of the portion a of the hook or thereabout, as shown at Fig. 4.
The hook a b will then closely resemble hooks of the common construction and
permit the unfastening of the clasp in the usual manner.

Improvements in Hooks and Eyes.
I, HEINRICH MENTZEL of 60 Sebastian Strasse, Berlin, in the Kingdom of
Prussia, German Empire, Ladies' Dress-maker, 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 :-
My invention relates to a clasp for dresses and consists of an eye of usual
construction, which is combined with a hook of an improved construction. My
invention therefore consists in making the hook with an elastic arm and providing
this arm with a nose which will permit of the easy introduction of the eye, but will
not allow the latter to slip out of the hook spontaneously.
My invention will be more readily understood by reference to the drawings, sent
in with Provisional Application, and in which :-
Fig. 1 is a side elevation of my improved hook.
Fig. 2 a plan of the same.
Fig. 3 shows the clasp in locked position.
Fig. 4 is a side elevation of my improved hook, the elastic arm being shown in 1
its depressed position, so as to release the eye.
Similar letters refer to similar parts throughout the several views.
In carrying my invention into effect, I construct the hook of the clasp as illustrated
by Figs. 1 & 2, that is to say, I form the hook of one piece of sheet-metal, which
is left plane in its main part a, and bent upwards and backwards at one of its ends,
so as to form a tongue, as shown at b. c are the usual eyes or holes at which the
stitches are made for securing the hook to the fabric. The middle portion of a b
is cut by two longitudinal incisions, extending nearly from end to end in such a
manner that the narrow central stripe d connects only with the main part a of the
hook, as will be seen at e, and is entirely separated from the hook at all other
points. The stripe d is bent hereafter into the shape shown at Fig. 1, so as to
form an elastic arm provided with a nosef opposite the end of tongue b, and pro-
truding with its end somewhat beyond the bend between a and b, as shown at g.
The protruding end portion of the elastic arm d need not be straight as shown,
but may be bent to any shape desired. In Fig. 5 h designates the eye constituting
the second clement of the clasp; this eye is of the usual construction, as already
mentioned.
The operation of my invention will be easily understood. When the eye his
inserted between the nose and the end of the tongue band pulled towards the
right (in Figs. 1 & 3), the arm d will yield on account of its elasticity and will be
depressed as much as is necessary for allowing the passage of the eye h into the
space between the nose and the bend of the hook a b. The eye h will then be
securely locked, and it will be obvious, that any attempt to force the eye h out of
the space in which it is confined will only result in pressing the nosef of the elastic
arm d upwards so as to close entirely the passage between tongue b and nose f.
When wishing to withdraw the eye from the hook a b, the protruding end g of
the elastic arm d is depressed with the finger, so that the main part of said arm
is brought in the plane of the portion a of the hook, or thereabout, as shown at
Fig. 4.
The hook a b will then closely resemble hooks of the common construction
and permit the unfastening of the clasp in the usual manner.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A hook for clasps, comprising a plane portion a, a tongue 6 bent thereto, and
an elastic arm d connected by one end only to the plane portion a of the hook,

page_text: provided with a nosef opposite the tongue b, and with an end portion g protruding
from the hook near the bend of the same, substantially as described, for the purpose
set forth.
