PROVISIONAL SPECIFICATION.
Improvements in Means for Closing Vessels, Boxes, Jars, and
the like.
I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention as
communicated to me by Eduard Wolff of Habelschwerdt, Silesia, Germany,
Manufacturer, to be as follows :-
-
This invention relates to improvements in means for closing vessels, boxes, jars,
and the like and the object to be attained by the invention is the use in the
manufacture of such closing means, of a brittle material such as glass or other
material which is both brittle and chemically neutral. For this reason the closing
of the vessel and the like is so arranged that the direction of the pressure
exercised for holding together the tightening surfaces is at right angles to the
latter, therefore the materials aforementioned are only used with reference to
compressive strength and not to strength of flexure. The cover for the vessel,
box, jar, and the like is made hollow and in the shape of a lens as used in
locomotives. The under part of the cover is provided with a shoulder which
serves to hold a washer or other filling material in position. In some cases the
washer or other filling material may be omitted, but the surfaces of contact are
then polished or ground true. The cover is held down by means of a
C shaped bow which presses on the head of the lens shaped cover in a downward
direction the ends of the bow engaging under the edges of the lip of the vessel.
This lip is curved inwards towards the centre of the vessel so as to form a seat
for the washer or other filling material or for the cover as the case may be.

Improvements in Means for Closing Vessels, Boxes, Jars, and
the like.
I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent do hereby declare the nature of this invention as
communicated to me by Eduard Wolff of Habelschwerdt, Silesia, Germany,
Manufacturer, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to improvements in means for closing vessels, boxes, jars
and the like, the object being to utilize for this purpose, a substance which is
chemically neutral, such as glass.
The invention is represented in the accompanying drawings as applied to a vase
shaped vessel; Figure 1 is a vertical section and Figure 2 is a section on the
line x-x of Figure 1.
The closing device which forms the subject of this invention is distinguished by

page_text: its being constructed after the style of the lenses employed in locomotives. The
hollow cover a is made lens shaped in its transverse section. The underside
however is contracted at a¹ in order to prevent any displacement of a tightening
ring or washer b which latter is supported from underneath by the seat c¹ cf the
vessel c.
This seat forms part of a V shaped groove in the neck of the vessel in
which said groove catches a C shaped spring d the ends of which are pronged to
prevent any unintentional alteration of position. On the upper surface of the
lens a lies the centre part of the spring d which is preferably bent slightly inwards.
The lens shaped cover may also be fitted with an aperture or depression into which
the centre part of the spring d may enter so as to keep the same in its proper
position.
A closing device such as is hereinbefore described is produced for the purpose of
obviating the contact of the substances to be preserved, with metal parts or pieces
forming the closing means. For this reason the invention is designed so as to
allow glass to be employed both for the vessel and for the cover. In order to be
able to exercise a proportionately strong pressure, without fear of breakage, the
cover is shaped like a hollow lens and the fastening of the C shaped bow is so
formed that the place receiving the pressure of the ends of the spring is in close
proximity to the ring shaped tightening surface or washer between the cover and
the vessel, whereby a complete distribution of pressure is effected. In some cases
the tightening ring or washer b can be dispensed with in which case the surfaces of
contact must be polished and ground true.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Means for closing vessels, jars, boxes and the like particularly distinguished by
the cover being shaped in the form of a hollow lens a which is secured in position
by means of a C shaped spring, whose ends engage in a groove in the vessel
situated under the tightening surface substantially as described and illustrated in
the accompanying drawings and for the purpose stated.
