Improvements in Closing-devices for Bottles.
I, AUGUST WILHELM SCHROEDTER, of 18, Markgrafen Strasse, Berlin,
Kingdom of Prussia, German Empire, Manufacturer 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 that kind of closing-devices for bottles, in which the
former is constantly connected with the latter, and in which the closing-cap proper
is, or may be, connected at both sides with a ring or ring-like part encircling the
neck of the bottle, and the novelty in this case consists in a special arrangement
of hinges and combination of parts as will hereinafter be more fully described.
In order to make my meaning more clear, I refer to the accompanying drawings,
in which similar letters denote similar parts throughout the several views, and in
which:
Fig. 1 is a side-view of my new device, shown in proper connection with a bottle,
and closing the same.
Fig. 2 is also a side view of the same part, the device being opened and the
main part of the bottle being left off.
Fig. 3 is an upper view of the parts as shown in Fig. 2 the neck of the bottle
being in section.
Fig. 4 also shows the parts of Fig. 2, but seen from the right hand side, the
bottle or its neck respectively being left off.
The ring a by means of which the whole device in its opened position as well as
in its closed one has in its middle part an ear a' and at both ends angular pieces a³ a³
which may be drawn against each other by a screw b so that the ring a may be
pressed thereby into a groove c provided on the neck d¹ of the bottle d.
A cross-piece e having at one side a projection e¹ with ear e³, and at the other
side an ear is connected by means of link f with the ring a. Said cross-piece e
holds the closing-cap proper 9 by aid of screw h, the angular head of which
latter is surrounded by a small shell i secured to the cross-piece e, in such a manner
as to be capable of rotating thereon, without removal therefrom. Cap g is guided
by a pin g extending into a suitable slot or projection e¹.
Now the main part of my invention consists in the arrangement of the flap k k
which, by means of its two apertures ³, is connected with eare of projection e
like a hinge. Part k of said flap forms a handle, part k¹ a hook. This hook grips
over the screw or pin 6 and is kept in that position by a spring 7 fixed to the
flap k k above ear e³, and pressing against cap e. Now, on putting the cap on the
mouth of the bottle, and pressing at the same time on handle k, hook k¹ will grip
over pin b, and will be coupled therewith as soon as handle k is released. The
bottle is closed now preliminarily. In order to effect finally a safe and tight closing,
the cap g is pressed firmly down on the mouth by the rotation of i, carrying with
it the angular head h¹, in threaded contact with h, or the angular head h¹ may be
rotated by a suitable key engaging with this or the cap i, or both.
I am well aware, that closing-devices of similar construction have been made
prior to my invention; in those older constructions, however, the last part of the
three-fold hinge, i.e. the flap k k¹ was secured to the ring around the neck; there-
fore, after having removed the cap from the mouth the flap remained in upright
position at the side of or parallel to, the neck, which latter, consequently was not
completely free. This drawback has been omitted in my new construction by
rranging the flap at cross-piece e so as to bring all the hinges into a con-
ecutive row

page_text: 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 :
In a closing-device for bottles:
1. The combination of neck-ring a having projections a' a' connected by screw
or pin b, and of cross-piece e carrying cap 9, and being connected with ring a by
link f, with flap k k¹ secured to cross-piece e and forming a coupling with pin b,
for the purpose as described.
2. The combination of neck ring a having its ends a² a bent off, and connected
by screw or pin b, and of cross-piece e carrying cap g, and being connected with
ring a by link f, with double-armed flap k k secured to projection el of cross-
piece e, and consisting of handle k and hook k¹, the latter catching over pin b, for
the purpose as described.
Dated this 19th day of June 1893.
