Improvements in Vessels for Transporting and Preserving Liquids.
We, FRANZ WELLEBA senior, of IV, Wohlleben-Gasse, 12, Chief Engineer of the
Austro-Hungarian State Railway Society, FRANZ WELLEBA junior, of V, Zeinlhofar-
Gasse, 3, Engineer of the Austro-Hungarian State Railway Society, and FERDINAND
UFFENHEIMER, of III, Disslergasso, 8, Clerk of the Union Bank, all in Vienna in the
Empire of Austria 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 :-
This invention relates to vessels for transporting or preserving liquids whereby the
liquids are not in any way affected by their contact with the sides of the vessels, nor
are the said sides attacked by the liquids. Owing to these properties, the said vessels
are especially suitable for transporting wine, acids and petroleuin.
In carrying out our invention we make the sides of the vessels of metal, stone,
wood, paper pulp, or other suitable substance and coat all the surfaces which come in
contact with the liquid with a perfectly impermeable layer of a material which will
resist the action of the liquid. In practice we have found ebonite to answer
particularly well for this purpose.
It is very difficult however to apply a close fitting layer of ebonite upon large
surfaces, and more especially on curved or cylindrical ones and such an ebonite
coating if applied would be liable to crack and to have fissures formed therein by
reason of the dilatation and contraction of such large surfaces through changes of
temperature, and the liquid would then reach the sides of the vessel. We therefore
construct the sides of the vessel of a number of annular sections, provided with
flanges, which are connected together by means of cold-rivets or bolts or screws. The
ends of the hollow cylindrical vessel, composed of a number of such annular parts,
are closed by heads or covers, secured to the flanges of the end sections by rivets,
bolts or screws.
As it is necessary that all surfaces liable to be wetted by the liquid should be coated,
the layer of ebonite is not only formed on the inner cylindrical or other shaped
surface of each annular section, but also on the contact surfaces of the flanges and on
the inner surfaces of the covers or heads. For the same reason, the inner surfaces
of filling and discharge holes, man holes and manhole covers are likewise coated with
ebonite.
In most cases the cold-rivetting or bolting of the flanges will be found to afford a
sufficiently tight joint. If required however, rubber packing rings may be interposed
at the joints.
The accompanying drawing represents a sectional elevation of a transporting and
storing vessel for liquids embodying our invention.
As can be clearly seen, this vessel is composed of a number of annular sections A
provided with Banges a, the inner surfaces of the said sections and the contact
surfaces of the flanges being coated with a layer of ebonite b. The ends of the
vessel are closed by plates B, the inner surfaces of which as well as those of the filling
opening C and its cover c, are likewise coated with ebonite.
If desired, the outer surface of the sides of the vessel may be coated with a suitable
non-conductor of heat.
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 :-
1. A vessel for storing and transporting liquids having all its surfaces liable to

page_text: 2. A vessel for storing and transporting liquids composed of a number of flanged
annular soctions and covers or heads, riveted, bolted or screwed together; the
insides of the said annular sections and covers and the meeting surfaces of the flanges
being coated with ebonito, substantially as hereinbefore described.
