page_text: A communication from AUGUST PIETZSCH, of 29, Lindenaustrasse, Dresden, in the
Empire of Germany, Manufacturer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. do hereby declare the nature of this invention to be as follows:-
The present invention relates to improvements in lids or closing devices for jars,
bottles, and the like and its object is to design a lid which effectually closes a vesseĺ
the edge of the opening of which happens to be sloping or inclined as well as those
otherwise constructed.
For this purpose the lid consists of two parts which are attached to each other; the
outer part of the lid surrounds the neck of the vessel and is held thereon by means
of projections formed on the neck of the vessel and under which are passed corre-
sponding flanges provided at the corresponding parts of the under edge of the said lid
and the inner lid is connected with the outer one by means of a screw which passes
through an internal screw-thread formed in the inner lid. This inner lid is guided by
two guides fastened to the outer lid and provided with bent ends which prevent the
screw from being entirely screwed out of the inner lid.
When the whole lid is placed on the vessel and the flanges of the outer lid turned
under the projections of the neck of the vessel, the said screw is turned thus lowering
the inner lid until it fits air-tight on an india-rubber or equivalent ring interposed
between the inner lid and the edge of the opening of the vessel.
The inner lid is guided so loosely that it will also adjust itself to the opening of a
vessel the edge of the opening of which should happen to be sloping or inclined.
Dated this 30th day of November 1888.

A communication from AUGUST PIETZSCH, of 29, Lindenaustrasse, Dresden, in the
Empire of Germany, Manufacturer.
I, Alfred JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. 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 relates to improvements in lids or closing devices for jars,
bottles and the like and its object is to design a lid which effectually closes a vessel the
edge of the opening of which happens to be sloping or inclined as well as those
otherwise constructed.
In the accompanying drawings;
Fig. 1 represents a vessel closet with this closing device.
Fig. 2 represents a section of the lid on the vessel.
Fig. 3 is a plan of the underside of the lid.
Fig. 4 represents a plan of the vessel and its rim.
For this purpose the lid (Fig. 2) consists of two parts which are attached to each
other; the outer part of the lid A surrounding the neck of the vessel and held thereon
preferably by means of projections formed on the neck of the vessel and under which
are passed corresponding flanges U provided at the corresponding parts of the under
edge of the said lid and the inner lid D connected with the outer one by means of a
screw S which passes through an internal seraw thread formed in the inner lid D.
This inner lid is guided by two guides fastened to the outer lid and provided with bent
ends H which prevent the screw S from being entirely screwed out of the inner lid.
When the whole lid is placed on the vessel and the flanges of the outer lid turned
under the projections of the neck of the vessel, the said screw
the inner lid until it fits air-tight on an india-rubber or equivalent ring interposed
turned, thus lowering
between the inner lid and the edge of the opening of the vessel.
The inner lid is guided so loosely that it will also adjust itself to the opening of a
vessel the edge of the opening of which should happen to be sloping or inclined.
Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondent, and in what manner the
same is to be performed, I declare that what I claim is :-
A closing device for jars bottles and the like comprising a lid such as A provided
with means for securing it to the jar and connected with an inner packing lid such
as D by means of a screw S by means of which screw the inner or packing lid can be
screwed down upon the edge of the vessel substantially as described and illustrated in
the accompanying drawings.
