WALTER ALFRED BARLOW of 6 St Pauls Churchyard in the city of London
Patent Agent and Engineer IMPROVEMENTS IN HERMETICALLY SEALED VESSELS
FOR LIQUIDS AND OTHER SUBSTANCES communicated to me from abroad by Anton
Luger of Vienna Austria
This invention relates to certain improvements in hermetically sealed vessels for
liquid and other substances, the object being to produce a vessel for holding
alimentary substances or liquids which by means of an air-tight cover, provided
with a suitable locking device, will keep its contents from contact with the air and
thus preserve them and which vessel at the same time may by its shape or form
be adapted to be used as a drinking vessel.
Heretofore, beer, wines and other liquids intended for beverages, have been kept
and transported in bottles also provided with devices for closing them hermetically
in order to preserve their contents, but the shape of these bottles and the arrange-
ment of their sealing device has rendered drinking out of them rather awkward and
unpleasant.
This inconvenience is overcome by this invention and in carrying the said inven-
tion into effect a vessel of the common beer tankard form is used but which formn
however is not essential as evidently a jar or vessel of any convenient shape size or
material may be employed.
Near where the upper end of the handle is connected with the body of the vessel
the former carries a metal band or clasp for the reception of which the handle is
preferably recessed.
.

page_text: The band which projects with its free end upward is held in place by a pin screw
or rivet which passes through both its shanks or ends close over the top of the
handle so as to hold the clasp tightly in its place.
To give the pin a better hold there may in the top of the handle also be provided
a recess for its reception or it may even pass through the handle itself.
Through the ends of the clasp there passes another pin rivet or screw which
connects hinge like to said clasp, a strap or cross piece, to which latter the cover,
which is preferably of the same material and nearly the same diameter as the
vessel is fastened by means of one or more rivets or screws.
This cover when closed projects with its lower side a little way downward into
the vessel and this projection is provided with a circumferential groove or recess
which serves for the reception of a rubber or other elastic band which, when the
cover is closed tightly fits into the mouth of the vessel, which is preferably a little
countersunk or chamfered off, so as to serve as a guide for the packing or tightening
ring and at the same time to secure a still tighter closing of the vessel.
Opposite to the handle the vessel is on the outside provided with a nose which
is preferably made of one piece with the vessel but which may also be fastened to
it in any suitable manner.
A latch. or link piece which is hinged to the other end of the strap or cross piece
turns down over the nose when the vessel is to be pressed tightly into the mouth
of the vessel whereby the latter sealed hermetically.
The cover being opened, swings out of the-way entirely and leaves the mouth of
'the vessel free for drinking out of. In vessels not solely intended for drinking
-vessels or where inconvenient the handle may even be dispensed with and in its
place a short projection or nose or any other mode for fastening this improved
sealing device may be substituted.

WALTER ALFRED BARLOW of 6 St Paul's Churchyard in the city of London
Patent Agent and Engineer IMPROVEMENTS IN HERMETICALLY SEALED VESSELS
FOR LIQUIDS AND OTHER SUBSTANCES a communication to me from abroad by
Anton Luger of Vienna Austria
This invention relates to certain improvements in hermetically sealed vessels for
liquid and other substances the object being to construct a locking or sealing device
which may be applied to vessels of any kind, such as cans, jars, bottles and such.
like and which may either be permanently attached to a vessel or be removable
therefrom.
This device is principally intended for jars bottles or vessels used for shipping
or preserving or conserving beverages or alimentary substances and in the former
case it may be arranged as to render the jar upon which it is attached fit for a
drinking vessel.
In the annexed drawing there are shown different views and applications of this
improved sealing device:-
Figure 1 being a vertical section of the sealing device in simple form mounted
upon a jar.
Figure 2 a top view thereof.
Figure 3 a vertical section of the device modified and provided with safety.
mechanism.
Figure 4 a plan of the device Fig. 3 with the cover or lid removed.
Figure 5 shows another modification of the device and
Figure 6 the application of the device as employed for sealing purposes applied
to the half cover of a metal can.
Figures 78 and 9 are details of the parts of the arrangement shown in
Figures 1 and 2.
Figures 10 and 11 details of the arrangement shown in Figs. 3. 4 and 6.
Similar letters of reference indicate corresponding parts in all the figures.
To illustrate the application of the simplest forin of this improved locking or
sealing device there is in Fig. 1 shown a vessel of the common beer glass
form but which latter however is not essential, as evidently a jar or vessel of any.
convenient size shape or material may be employed.
Near to where the upper end of handle b is connected with the body of the
vessel a, there is provided a metal band or clasp c, c' for the reception of which the
handle b may be recessed as shown-Clasp c, c' which projects with its free ends
upward, is held in place by a pin, screw or rivet d which passes through both
its shanks close over the top. of the handle 6 so as to hold clasp c, c' tightly in
its place.
To keep pin d from shifting, there may in the top of handle b also be provided a
recess as shown for its reception or it may even pass through the handle itself.
Through the ends c' of the clasp passes another rivet, pin, or screw e which connects
hinge like to the said clasp c a strap or cross piece f to which cover g which may
be of any material is fastened by means of of one or more rivets or screws h.
This cover genters with an annular projection into the mouth of the vessel and
is around this projection provided with a circumferential groove or recess which
serves for the reception of a rubber or other elastic ring or gasket i which when
the cover is closed tightly fits into the mouth of the vessel. The latter is preferably

page_text: countersunk or chamfered off a little on the inside edge so as to provide a proper
seal for the packing or gasket.
Opposite to the handle the vessel is on the outside provided with a projecting
tooth or nose K which in this case similarly to the handle is made of one piece
with the vessel.
A latch or link which is binged at m to the other end of strap f turns down
over nose K when the vessel is to be closed and causes packing ring i of the cover g
to be pressed tightly into the mouth of the vessel whereby said vessel is sealed
hermetically.
The cover being opened swings out of the way entirely and leaves the mouth of
the vessel free for drinking out of.
The vessels which are not intended for drinking purposes the handle may be
dispensed with or be made removable as well as the whole sealing device by giving
it the following construction. A metal ring n Figs 3, 4 and 5 whose inside
diameter approximately corresponds to the outside of the neck or part near the
mouth of the vessel upon which it is to be used is provided with two projections
K and c.
This ring n may be formed of two halves or of one piece and opens at
one place where the ends are bent outward as shown in Figure 5 or outward and
upward as shown in Figure 3. In both cases these ends form what has been
denominated projection c. In the former case clasp c¹ is attached to projection c
in the same manner by a pin d as in figure 1 to handle b. In the latter case
clasp c is substituted by or formed of ends c of ring n figure 3. Here the ring is
held tight upon the vessel by a screw or rivet d' passing through both ends c¹.
The upright parts c¹ of clasp c or ring n are near their upper end provided with
horizontal or nearly horizontal slits of which although there is but one in each
required it is preferable to have two or even more to compensate for any bending
or giving way of any of the parts by shifting pin e into the next lower pair of
slits. These slits are in many cases more to advantage than the simple hole in
clasp c of figure 1 as they permit a lateral motion of pin e whereby the cover may
readily find its seat.
These
Pine is fast in the strap or cross piece of which fits between ends c¹ and which
may be short and fastened to one side of the cover or lid as shown in figure 6 or
may extend across to the opposite side of the cover where it carries a pin m
upon which swings the locking bar or latch . This latch or locking bar may
instead of the form shown in figures 1 and 7 be serrated or toothed as at o.
teeth interlock into one or more teeth p with which projection K is provided.
Projection K may be solid as shown in figure 5 or it may be formed of two parts
standing fork-like as shown in figures 3 and 4 between which parts tooth or teeth p
are situated.
To prevent the accidental disengaging of teetli o and p the forked part of
projection K is provided with a safety device which consists of a small plate q
(figures 3, 4 and 11) to which a pin is fastened which slides in a hole in the small
plate & fastened between the parts of projection K at or near their ends.
Plate q
is by means of two webs t guided in corresponding slots u see Fig 6. Between the
fixed plates s and sliding plate q a spring v is arranged in such manner as to press
the latter upon latch and this against projection k whereby teeth o and pare
securely kept engaged with each other.
Figure 5 shows the use of the simple or one toothed latch 7 of figures 1 and 7 in
combination with projection K of ring n which projection K in this case is solid
and provided with several teeth instead of one as in figure 3.
The reason for having several teeth instead of but one either on the latch or the
ing or on both is the same as for providing ends c' with several slits as before
described viz to compensate for the bending of any of the parts or for the "giving"
of the elastic packing where such is employed.
It is evident that the mechanism described can be fitted to any cover,
lid or
stopper of any form, size or material and where a handle is required the same may
be attached in the manner shown in fig 3'

page_text: As already mentioned strap ƒ may extend right across the cover, lid or stopper
and be of one piece, or it may be substituted by two short pieces of metal for
carrying pins e and m respectively fastened in suitable manner on opposite points
of the cover lid or stopper.
In figure 6 the application of the device for sealing upon the half covers or lids
of metal cans is shown.
To prevent the elastic gasket from becoming loose or falling off from the cover
the latter may be made of two halves between which the flat gasket i is placed as
shown in figure 5; the whole is held together by a screw bolt or rivet h.
When used upon glass vessels, which are transparent, ring n may on its inside be
provided with ornamental strips or designs of paper or other material for decorative
purposes.
Having thus described the nature and particulars of the said invention
I claim :-
Firstly. In jars or vessels for preserving alimentary substances or liquids the
combination of cover g. with packing ring or gasket i, clasp c, strap or cross piece f,
latch and nose K constructed and operating as and for the purpose herein set forth
and as shown by the accompanying sheet of drawings.
Secondly. The combination in a drinking vessel of nose or projection K, cover or
lid g with packing ring or gasket i, clasp c strap or cross piece f and latch as and
for the purpose herein set forth and as shown by the drawings.
Thirdly. The combination with a cover lid or stopper for vessels for liquid or
other substances of ring n with opposite projections K and c (said part cor its strap
or upright ends c¹ provided with one or more slits for the reception of pivot e and
projection K provided with one or more teeth p) of latch provided with one or
more teeth o and of a safety device consisting of plate q, pin r, spring vand plate s
constructed and operating as and for the purpose herein described in reference to
and shown by the accompanying sheet of drawings.
Fourthly. The combination with a cover, lid or stopper for vessels of ring n with
opposite projections k and c, strap f and latch as and for the purpose herein set

drawings.
In witness whereof I the said Walter Alfred Barlow have hereunto set my
hand and seal this sixteenth day of March in the year of our Lord one
thousand eight hundred and eighty-three.
