Improvements in Closing Devices for Jars, Bottles, Boxes,
and the like.
"
I, NEWNHAM BROWNE, of 73, Cheapside, in the City of London, Fellow of the
Institute of Patent Agents do hereby declare the nature of the said invention for
"IMPROVEMENTS IN CLOSING DEVICES FOR JARS, BOTTLES, BOXES, AND THE LIKE,"
which invention has been communicated to me from abroad by Albert Lasch, of
Dresden, Saxony, in the Empire of Germany, Manufacturer of Metal Goods, and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement, that is to say -
This invention relates to a closing device for jars, bottles, boxes and the like which
is convenient in use and not liable to wear so that it may be used again and again for
closing such vessels hermetically.
This device is shown in the accompanying drawings.
Figs. 1 and 2 are elevations taken at right angles to one another.
Fig. 3 is a plan view.
Fig. 4 is a plan of the lid.
Figs. 5 and 6 are sections on the lines A, B and C, D and show the closing devices
Joose.
Figs. 7 and 8 show the device applied to a vessel.
a is a capsule shaped lid of metal with a horizontally projecting flange a¹ and
slots a² and a on the upper surface. b is a hollow piece sliding into the part a. c is
a cylindrical ring of india-rubber surrounding, as shown in figs. 5 and 6 the bottom
of the part a and also the periphery of the part b the edges engaging with grooves
in a and b. From the part or piece ba lug d projects upward and carries pins or
studs ; it passes through the slot a³ and projects beyond the lid a.
e is a slide moving on the lid a and between ribs a; a projection e¹ engaging with
slot a prevents its being lifted off as lateral extensions of the projection e bear
against the inner side of lid a. In the flanges of the slide e inclined slots e³ are
provided and with these the pins or studs d' of lug d engage. When the slide
assumes its extreme position on the lid to the left of Figs. 1 and 5 then the piece b is
in it's lowest position, as the pins d' are in the lowest part of the slots e (as shown in
figs. 5 and 6) and the rubber ring bears against the peripheries of a and b.
When the closing device has been so inserted into the aperture of the vessel to
which is to be applied that the projecting rim a¹ of lid a hears against the lip of such
aperture (see figs. 7 and 8) and if the slide e is moved inwards, that is from left to
right of the figures in the drawing, then the inclined slots e' in the slido e act upon
the pins or studs d' on lug d and cause the hollow piece b to be raised. This hollow
pieces approaches the lid and the distance between the edges within which the india-
rubber ring lies is so reduced that the latter ceases to lie flat, as in fig. 5 and 6, and
curls or buckles up. The curvature bears against the sides of the vessel as seen in
figs. 7 and 8 and the vessel is thereby hermetically closed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent I declare that what I claim:
A closing device for jars, bottles, boxes and the like, consisting of a lid a having
.

page_text: slots a' and a; of a hollow piece b with lug d and pins or studs d'; an india rubbor
ring a which is flat in cross soction and placed as specified, and a slide e with slots ³,
the whole being combined arranged and operating as set forth and as shown in the
drawing and in such manner that the curling up of the indin rubber ring causes the
same to press against the inner sides of the vessel so as to close the Intter.
Dated the Eighth day of May 1890.
