An Improved Device for Facilitating the Opening of Preserve-jars
and other Vessels Provided with Spring Caps or Covers.
I, ADOLF SCHILLER, of 12, Rheinallee, Godesberg a/Rhein, in the German Empire,
Government Architect, do hereby declare the nature of this invention to be as
follows:
For opening bottles, which are closed by means of a cork secured by wire-loops,
a tool or implement is used comprising a handle having a supporting-foot and
a gripping-arm.
By the lever-action produced, when pressure is exerted on the handle, the cork
is drawn bodily out of the bottle and at the same time the flying-out of the cork
by reason of any internal pressure is prevented. An uncorking device of this kind
cannot however be combined with a bottle without rendering the handling or
transport of the bottle considerably more difficult.
In the opening device for the caps or covers of preserve jars and the like forming
the subject of the present invention, the system of levers for producing the lever
action consists of two wire bows or loops, of which one serves as a support for the
other bow or loop acting as the lever proper, whilst between the two bows or loops
is provided a pivotal connection in such a manner that the opener can be applied
to the jar without making the handling and packing thereof more difficult, since
both loops or bows lie normally one within the other and fit closely against the
outside of the neck of the bottle.
In carrying my said invention into practice, I preferably provide two wire-bows
or loops of U-shaped form which are bent round at right angles at their ends.
The ends of the shorter bow or loop engage in eyes formed in the longer bow or
loop so that a pivotal connection is made in this way between the said bows or
loops.
In order to apply the opening device to a jar or other vessel, certain modifications
must be made both in the cover as well as in the said jar or vessel. For instance,
a spring-tongue or projection on the cover is provided with an eye which is formed
by stamping out a small strip of the sheet metal; the jar or vessel itself is provided
with an external bead or annular flange which can easily form an ornamental
or supporting edge.
Normally the two bows or loops lie one within the other.
When it is desired to use the opening device, the bent-round ends of the longer
bow or Loop are introduced, by the exercise of a slight pressure, into the eye in the
tongue or projection on the cover; then the lower part of the shorter bow or loop
is placed on the ring on the jar or vessel and pressure exerted on the free part of
the longer bow or loop. In this manner the cover is gradually raised, this taking
place all the easier since, by reason of the particular construction, the effects of the

page_text: flange R which can easily form an ornamental or supporting edge. Normally,
the two bows or loops lie one within the other, Figure 1.
When it is desired to use the opening device, the bent-round ends a¹ a¹ of the
longer bow or loop a, are introduced, by the exercise of a slight pressure, into
the eye in the tongue or projection F on the cover; then the lower part of the
shorter bow or loop 6 is placed on the ring R on the jar or vessel and pressure
exerted on the free part of the longer bow or loop a. In this manner the cover is
gradually raised, this taking place all the easier since, by reason of the particular
construction, the effects of the lever and its supporting lever or loop come into
play simultaneously, which causes removal or lifting of the cap or cover both
upwards as well as outwards.
In cases where the cover is arranged in a perfectly definite position, a short
projection for supporting the shorter bow or loop 6 can be used, corresponding in
position to the eye on the cover, instead of the annular bead or flange R.
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:-
A device for opening preserve-jars or other vessels having spring caps or covers,
comprising two U-shaped bows or loops, one of which, when applied to a bead
or projection on the vessel, serves during use as a support for the other bow or loop
which is applied to the edge of the cover, these bows or loops being pivotally
connected together in such a manner that they normally lie one within the other
so as not to interfere with the handling or packing of the jar or other vessel,
substantially as described.
