PROVISIONAL SPECIFICATION.
Improvements in Lids for Pitchers or similar Receptacles.
I, BRUNO WESSELMANN of Hamburg, in the Empire of Germany, Manufacturer,
do hereby declare the nature of this invention, to be as follows:-
This invention consists in an arrangement having for its purpose to produce an
almost hormetical and at the same time secure closing of a pitcher or similar receptacle.
This end may be attained for instance by means of a wedge screw or bolt. On the
upper part of the pitcher, opposite to the mouth of the same a cylindric chamber is
provided parallel to the longitudinal axis of the receptacle. Said chamber contains a
bolt, the head of which is pressed by a screw spring against the cam-shaped
extremity of a bow secured to the lid of the receptacle, said extremity being connected
hinge fashion with the upper part of the chamber. To open the lid the resistance of
the spring is to be overcome and the latter subsequently causes the lid when in a
certain position to close. The lid is secured from unauthorised opening by passing
a wedge crosswise through chamber and bolt, which are provided to this end with
corresponding openings, thus fixing the bolt and the lid. The wedge is protected from
being undone by means of a padlock or other device.
If the lid is to be fixed by means of a screw or pin, the bolt is provided with a
loose cap in lieu of the stationary head and below with a screw thread or lateral
pivot. In the one case the bolt is screwed onto the loose cap, in the other case it is shifted,
upward, thus causing the lateral pivots to pass corresponding grooves provided on
the bottom of the chamber. As soon as the pivots are inside the chamber the bolt is
slightly turned about its axis, thereby the pivots come in contact inside with the
bottom of the chamber and the bolt ceases to move downward, that is to say the lid
of the receptacle is secured from being opened.
Also for this arrangement, a padlock or other locking device may be employed.

COMPLETE SPECIFICATION.
Improvements in Lids for Pitchers or similar Receptacles.
I, BRUNO WESSELMANN of Hamburg, in the Empire of Germany, 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 -
The object of this invention is a device for hermetically closing pitchers or similar
receptacles and securing the same from unauthorized opening.
Referring to the accompanying drawing
Fig. 1 is a side view and partial section of the upper part of a pitcher with the
improved device applied thereto.
Fig. 2 is a rear view of the device, while
Figs. 3 and 4 illustrate modifications thereof.
In the device shewn in Figs. 1 and 2, the purpose of securing the pitcher against
unauthorised opening is attained by the application of a wedge, while in the
modifications represented by Figs. 3 and 4 the same effect is produced by aid of a
screw and so-called "bayonet" closing respectively.
The head of the bolt a, Fig. 1, is pressed by the action of the spiral spring c
provided in the chamber b, energetically against the cam-shaped part of the bow e
connected with the lid d. On opening the latter, the resistance of said spring is to

page_text: be overcome, which causes the lid, when in a certain position, to snap down and
close the receptacle. The device is secured in its closed position by passing a wedge f,
which may be connected by a cord or chain with the receptacle, through a corre-
sponding opening of the bolt, as shewn. In addition to this closing, the pitcher may
be locked by attaching a padlock or similar device to the wedge by aid of an aperture g
provided therein.
For this
In the modifications illustrated in Figs. 3 and 4, the spiral spring abuts with its
top part against the cylindric cap h and presses the same onto the eccentric portion
of the bow e, whilst the bolt a serves to fix the cap in the position shewn.
purpose, the bolt is either screw-threaded at the bottom Fig. 3, to allow the cap to be
screwed fast, or is provided with lateral projections or nozzles i Fig. 4, to which
correspond notches provided in the bottom of the chamber and allowing the bolt to
be raised onto the cap, and secured in its position by 'turning it for about 90° about
its axis. To effect an additional tightening, the bottom of the chamber may be
made to slightly ascend in the direction of the turning of the bolt.
The cyc Figs. 3 and 4 and that provided at the lower extremity of the bolt a
are destined to receive a lead-seal, lock or similar contrivance for obviating unauthorised
opening of the vessel.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
In mechanisms for closing the lids of pitchers or similar vessels, the application of
1) A bolt a, adapted to be secured in a certain position by means of a wedge, f,
in combination with a spiral spring c provided in a chamber substantially as and for
the purpose set forth.
2) A bolt a adapted to be secured in a certain position by means of a screw-thread,
or nozzle and notch, in combination with a cap h and a spiral spring c, provided in a
chamber b, substantially as and for the purpose set forth.
