COMPLETE SPECIFICATION (AMENDED).
Improvements in the Method of Fixing Stoppers to Vessels Containing
Gaseous Liquid or other Substances, applicable to the Fixing of
Tops of Seltzogenes or Gazogenes and the like.
JOSEPH EUGSTER and JOHN KOERTGEN both of 2 Gresham Buildings,
Guildhall, in the City of London, Manufacturers, 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 in particular to the apparatus known as the
seltzogene or gazogene constructed for the preparation at home of aerated water
and this invention has for its principal object an improvement in the method of
fixing the tops of such vessels without the means of the screw on the tap aud on the
neck of the vase as hitherto employed for the purpose, the main objection to which
system is, the corrosion of the said screws, consequent upon the metallic oxidation
set up by the carbonic acid gas generated therein, in conjunction with the india
rubber used for sealing the joint; such corrosive action resulting in the frequent
fixture or locking together of the two screws beyond possibility of release thereby
rendering the taps and apparatus useless. To obviate the disadvantages above
referred to, we employ a clamp or clasp constructed as hereafter described, by
which the screw on the tap and likewise that on the neck of vase are both dispensed
with, at the same time the aerated water in the apparatus is kept absolutely gas
and air tight.
The clamp or clasp is easy to adjust and take off and by its employment
considerable economy is effected in the wear and tear of the india rubber washer
required, the friction and wear on same through screwing the tap on and off being
entirely dispensed with.
That the nature of our invention may be the better understood we will
proceed to explain same with reference to the accompanying sheet of drawings, in
which:
.
· Fig. 1 represents an elevation of the top or metal portion of a seltzogene or
gazogene constructed without the usual screws for screwing down the same to the
vase but having bevelled rims D H formed thereon over which the clamp or clasp
fits as shewn at Figure 4.
Fig. 2 is an elevation also of the seltzogene tap but with the clamp adjusted and
fastened to same in manner proposed.
Fig. 3 shows a plan view of the clamp or clasp which is composed of two
movable jaws 1, 2 pivotted together and fitted with a tightening piece 3 and thumb

page_text: screw E. The end of the movable jaw 2 is bifurcated and a recess G is formed
therein as indicated in dotted lines wherein the collar e of the thumb screw E fits
when the latter is screwed up, thus securely fastening the jaws of the clamp or
clasp together. The inner faces of such jaws are grooved and bevelled as shewn
at Figures 4. 5. 6. 7. 8. and 9 of the accompanying drawings.
Fig. 4 is a view partly in section and partly in elevation shewing the bevelled
faces F of the clamp or clasp fitted over the bevelled rims D. H.
Fig. 5 is also a section of the clamp shewing interior facings as we propose
making them in present instance whilst
Figs. 6, 7, 8 & 9 represent sections of the clamp made in exterior appearance as
Fig. 3 but constructed or shaped with different facings inside all or either of which
are practical in manufacture and equally applicable for the purpose of this
invention.
The method of attaching the tap to the seltzogene would be thus: The tap A
Fig. 1 which is usually made of white metal & fitted with an india rubber washer
or ring at B is inserted into vase C. The washer B resting upon the metallic
rim D of vase C.
The clamp Fig. 3 is then adjusted over the bevelled rims D. H as shewn in
Figures 2 & 4 and the thumb screw E tightened to the required degree. The
action being that by tightening the screw E the slanting faces or inclined planes
of the clamp as shewn by Fig. 4 F are brought to bear upon the bevelled rims
which are thereby compressed evenly and securely and with the aid of the india
rubber washer B a hermetically sealed joint is obtained and without any screwing
down of the tap as hitherto the case.
The clamp or clasp fastening as shown Fig. 3 can be made of brass, copper,
gun metal, tin or any other suitable metal or material, either with one or more joints
& could if preferred be hinged to the tap of the seltzogene having essentially
the same features as the detachable pattern but constructed with a hinge to each
jaw, further the tightening arrangement of clamp or clasp when adjusted to the
seltzogene tap might equally well be accomplished by replacing the thumb screw E
with a small excentric or crank with turn piece or key the same to work in the slot
at end of clamp Fig. 3 G.
Our invention is also applicable for hermetically closing jars, bottles, tins, and
other like vessels and receptacles, provided that the rims of the necks and stoppers
of the same are bevelled in the manner already described and as shewn as regards
jars and bottles at Figure 10, and, as regards tins, at Figure 11 of the accompanying
drawings.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :
As a novel means for hermetically closing a seltzogene, gazogene, or other vessel
the neck and stopper whereof are provided with bevelled rims in the manner
herein before specified a clamp or clasp composed of two movable jaws pivotted
together and having their inner faces grooved and bevelled so as to fit over said
: bevelled rims, such clamp or clasp being fitted with a tightening piece and thumb
screw and otherwise constructed arranged and fitted all substantially in the manner
herein before described and shewn.
Dated this Twenty-second day of January 1894.
