We, FRITZ SCHLEY of No. 10 Schützenstrasse, Berlin, S.W. in the Empire of
Germany manufacturer and PAUL BOUVERON of No. 146, Jacobstrasse of the same
place, merchant, do hereby declare the nature of this invention to be as follows:-
The present invention has for its object an improved system of safety hooks, which
are especially applicable for wearing apparel, sheets, curtains seat cloths, marquees,
and other similar objects.
This system consists of two organs or parts namely a hook proper, and a loop, eye,
or hook-holder. All the systems of hooks hitherto invented have the disadvantage
of allowing the parts connected thereby, to become too frequently and easily
disconnected and at unexpected times, which is inconvenient in the case of garments.
The prevention of this disadvantage is the object of this invention.
The improved system possesses this peculiarity, that its organs can only be loosened
by exerting a comparatively great effort whilst they can be connected without any
difficulty.
For this purpose the hook is provided with a blade or tongue piece, and the loop
with two elastic branches, the latter being so arranged as to exert a certain pressure
on the said tongue piece, which rests against their under sides, when the hook-has
entered into the cramp, and will only yield under a pressure in the opposite direction.
The loop is formed with two branches, which possess a springing action. On the
other hand the hook terminates in a blade or tongue piece. When the hook has
entered into the loop, the tongue bears against the under part of the said branches.
Owing to their elasticity the latter have a tendency to retain the tongue, and it is
only by exerting a pretty strong pressure on the rear part of the hook that the tongue
piece can be induced to pass between the branches, and so free the hook.
For the purpose of giving the loops a firmer hold on the parts to be secured, they
can be sewn not only at the eyes, but also at eyes or loops at the opposite end of
the elastic branches, but care must be taken that in so doing, the springing action of
the branches is not interfered with.

page_text: Hooks and loops can be made of bent wire, sheet metal, or metal strips. When
the hooks are made of sheet metal, or metal strips, it is advisable to punch the tongue
piece, so as to form it to the required shape. In the case of loops, made of metal
sheet, or strips, the springing cheeks are best united together so as to form a small
plate, which is caused by the pressure of the tongue piece to spring in the direction
of the pressure each time the fastening device is closed or loosened.

Improvements in or relating to Safety Hooks.
We, FRITZ SCHLEY of No. 10 Schutzenstrasse Berlin S.W. in the Empire of
Germany Manufacturer, and PAUL BOUVERON of No. 146 Jacobstrasse of the same
place Merchant, 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 :-
The present invention has for its object an improved system of safety hooks, which
are especially applicable for wearing apparel, sheets, curtains, seat cloths, marquees,
and other similar objects.
This system consists as usual in the combination of two organs or parts, namely a
hook proper, and a loop, eye, or hook-holder. All the systems of hooks hitherto
invented, have the disadvantage of allowing the parts connected thereby, to become
too frequently and easily disconnected and at unexpected times, which is inconvenient
in the case of garments. The prevention of this disadvantage is the object of this
invention.
The improved system possesses this peculiarity that its organs can only be loosened
by exerting a comparatively great effort, whilst they can be connected without any
difficulty.
For this purpose the hook is provided with a blade or tongue piece, and the loop
with two elastic branches or an elastic small plate, the latter (branches and plate)
being so arranged as to exert a certain pressure on the said tongue piece, which rests
against their under sides, when the hook has entered into the crap, and will only
yield under a pressure in the opposite direction.
The invention is best understood by referring to the annexed drawing, the six
figures of which show a hook made in accordance with this system. It is understood
that the right is reserved of modifying the shape and size thereof.

page_text: When
In these figures, s is the loop, and the hook, which engages therewith. As seen
in the Figs. 1 to 4 the loop is formed with two branches a, a, which possess a springing
action. On the other hand the hook terminates in a blade or tongue piece z.
the hook has entered into the loop, the tongue z bears against the under part of the
said branches. Owing to their elasticity the latter have a tendency to retain the
tongue, and it is only by exerting a pretty strong pressure on the rear part b of
the hook that the tongue piece can be induced to pass between the branches a, a,
and so free the hook.
For the purpose of giving the loops a firmer hold on the parts to be secured,
they can be sewn, not only at the eyes o, o, but also at the parts c, c, but care must
be taken that in so doing, the springing action of the branches a, a, is not interfered
with.
Hooks and loops can be made of bent wire, sheet metal or metal strips.
When the hooks are made of sheet metal or metal strips, it is advisable to punch
the tongue piece 2, so as to form it to the required shape as shown by Fig. 5. In the
case of loops made of metal sheet or strips, see Fig. 6, the springing cheeks are best
united together so as to form a small plate a', which is caused by the pressure of the
tongue piece z to spring in the direction of the pressure each time the fastening device
is closed or loosened.
Having now particularly described and ascertained the nature of the said inven
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
A hook forming the one element of a safety hook connection, and having a blade
or tongue piece z, as described and for the purpose stated.
