COMPLETE SPECIFICATION.
Means or Devices for Fastening the Lids or Covers of Jugs, Tankards;
and the like.
I, JOSEF GAWRON, of 43, Steinmetzstrasse, Berlin, in the German Empire,
Engineer, 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, reference being had to the accompanying drawings and to
the letters and figures marked thereon, that is to say:
This invention relates to improved means or devices for fastening the lids or
covers of jugs, tankards, and the like, and obtaining an equal pressure thereon
while, at the same time, providing an air tight closure.
To render my invention readily understood, I will describe the same fully with
reference to the annexed drawings, in which:
Figs. 1 and 3 are side elevations of a jug showing its lid fastened, and open,
respectively.
Fig. 2 is a front elevation of the same, fastened.
Figs. 4 and 5 shew two modified fastening devices.
Figs. 6 and 6 shew a further modification.
Fig. 7 is a front elevation of this last modification.
Figs. 8 to 10.shew various modifications of a detail of the invention.
For the purposes of my invention, I employ a bow, strap, or yoke d, and pivotally
support it in enlargements or lugs i formed on the vessel, said bow being so
arranged as to pass over the lid or cover f until arrested by the stop g. To release
this bow, so as to allow the lid to be raised or opened, it is pushed to the left, with
the arrangement shewn in Fig. 1, but to the right with the arrangement shewn in
Fig. 3. It is provided with a lever a terminating in an eccentric b adapted to
enter a locking recess o in the lid or cover, when this latter is closed. To open the
lid, the lever a is raised, thereby withdrawing the eccentric b from the recess.
bow thus released falls, by its own weight, to the left over the lid and down against
the side of the vessel. Or, as shewn in Fig. 3, the bow may be arranged to fall to
the right against the handle p. In this latter arrangement, the lever a serves at the
same time to raise the lid. To this end, the shoulder c of the lever ab is so
arranged as to come against the bend m of the bow d and so prevent the further
turning of the lever ab on the straight part of the bow d.
The
The bow d must be flexible or yielding so as to enable it to act as a safety valve,
should the pressure in the interior of the vessel rise too high.
In Fig. 4 the bow is shewn provided with a roller n instead of with a lever,
while in Fig. 5 the lever a is arranged in line with the said bow.
Figs. 6, 6, and 7 shew modified arrangements wherein the lever ab is replaced
by a bow and links u working on three axes r, s, and z, s being on the lid or cover, z
on the vessel, and r forming the connection between the links u and bow d. In
Fig. 6, the fastening device is shewn in its locked position, in full lines, but can be
released by moving the bow d in the direction of the arrow. The respective
lengths of the links u and bow d are such as to retain the lid in its open position,

page_text: as shewn in dotted lines, Fig. 6. The device is retained in position on the closed
lid or cover by contact with the extensions s' on the axis s, Figs. 6 and 7, while in
Fig. 6 it is secured in position by the extremity d¹ of d bearing against the lid or
cover f.
i
As it is not always possible to ensure the pivot holes in the enlargements or
lugs being located exactly on both sides of the vessel, and at the same distance
from the upper edge of the same, I overcome this difficulty by the following means.
The pivots of the bow d are supported in bearings q, or q', which may be polygonal,
as in Figs. 8 and 9, or disc-shaped, as in Fig. 10, and be provided with eccentrically
arranged holes, and said bearings are fitted into recesses in the lugs in such a
manner that they can be turned round and so enable the distance between z and the
top or edge of the vessel to be readily adjusted. By these means also, the pressure
of the fastening device can be regulated.
The lid or cover is provided with suitable air tight material, such as rubber,
cork, or the like, covered with metallic foil to prevent organisms, which may exist
in said material, entering the vessel.
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. A resilient fastening device, for the lids or covers of vessels, pivotally secured
in the central vertical plane of the vessel and characterised by a bow, strap or yoke,
having an eccentric lever adapted to be moved towards the middle of the lid or
cover, and then by lowering such lever on to the lid or cover render it air tight,
substantially as described.
2. The modified arrangement in which the eccentric lever is replaced by a bow
and links adapted to work on axes arranged one on the lid or cover, the other on
the bow, so that when moved in the direction of the arrow y, until the arms of the
bow strike against the extensions s¹ of the axis s (or until the part d' of the bow
strikes against the lid) an air tight closure is effected, but when moved in the
opposite direction the lid is raised and retained in such position, substantially as
described with reference to Figs. 6, 6, and 7 of the drawings.
3. In a fastening device as under Claim 1, the arrangement in which the lever
is provided with a shoulder (Figs. 1, 2 and 3) for enabling it to be used for releasing
said fastening device and for opening the lid by turning it in one direction,
substantially as described.
4. The combination, with the arrangement claimed under 1, of a stop (such as g)
for arresting the bow d in its central position above the vessel when closing it, said
stop being situated to the right of the bow when this latter is constructed to bo
released by turning it to the left, as in Fig. 1, or to the left when the bow is to be
turned to the right, as in Fig. 3.
5. In a fastening device, as claimed under 1, the arrangement of the bearings
(9 or g¹) having eccentric holes and capable of being adjusted so as to regulate the
position of the pivots of the bow and the pressure of such bow on the lid or cover,
substantially as described with reference to Figs. 8 to 10 of the drawings.
