I IDA FRANZISKA CLASEN Merchant, of Berlin in the Empire of Germany do
hereby declare the nature of this invention and in manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
This improved fastening is so arranged that, upon pushing together or shutting up,
an automatic fastening is effected, while the work of opening is easily done by
pushing back the fastening hook, though no automatic opening of the fastening is
possible.
Figures 1 and 2 show a single fastening and Figures 3 and 4 a double fastening.
The fastening Figures 1 and 2 consists of the hook part a, forked plate or part e
with forks dd, and the fastening stud g.
The hook part a rests at f on the plate e, and can turn round, and is continuously
pressed upon by the spiral spring i, which lies at k in the cage or guide on the plate e.
The hook b, closes up the space between the forks d d with the exception of an
aperture of suitable size h Figure 1. Into this aperture the stud g enters, being
introduced between the ends of the forks dd, when sliding along the hook surface b,
it is pressed into the hook part a, until the stud g is caught in the aperture h by the
shoulder forming the hook b.
In opening the fastening, the hook is pressed back by means of the pin / on the
arm or fork c of plate a so that the stud is released and can pass out from the
forks d d.
In the double fastening (Figures 3 and 4) two studs g¹g' are provided, which are
caught by hooks b¹ b'.
The hook parts a' a' with the hooks 61 6¹ thereon are fastened at fi f¹ on the
plate e and can turn thereon, and they move on the plate e¹ which is formed at one
side or point into the tooth or projection d' and guides the studs g¹ gl as they are
pushed in when closing the fastening. The hook parts al a¹ have teeth formed
thereon at n which gear into each other, and cause the hooks b' 6' to open at the same
time and to the same extent.

page_text: At the opposite ends mm of a' a¹ to the hooks b₁₁ is placed a spiral spring or
springs, held by the cylinder or guide ¹ on the plate e¹; this spring always causes
the hooks to close. When the studs g'g' are pushed in, they slide along the
tooth d³, at the same time sliding along the curved surfaces of the hooks 6' 6', until
the latter catch the studs g¹ g' in the apertures h¹ h¹ (Figure 4) formed by the tooth d¹
and the hooks b¹ b¹.
By means of the pin 1, the two hooks 61 6¹ are opened at the same time in order to
undo the fastening, and release the studs g¹ g'.
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. The improved construction of fastenings for gloves, trunks, corsets and other like
purposes consisting of the part a turning on the pin or axis f with the hook b thereon
which by means of the spring i is kept closed across the forks d d and catches and
retains the stud g all substantially in the manner and for the purposes hereinbefore
described and represented in Figures 1 and 2 of the drawings hereto annexed.
2. The improved arrangement and construction of a double fastening for gloves,
trunks, corsets and other like purposes; consisting of the two hooks 61 b¹ turning on
the axis f¹ and provided at n with teeth gearing into each other, which hooks move
over the plate e with the point or projection d' thereon and are pressed together by
the spiral spring or spring it; and the two studs g'g', which catch in the opening h¹ h¹
formed between the tooth d¹ and the hooks b₁ ball substantially in the manner and
for the purpose hereinbefore described and represented in the accompanying
drawings.
3. The improved arrangement and construction of fasteners as and for the purposes
hereinbefore described and represented in the accompanying drawings.
