I JOSEPH THEODORE DANN of 32 Canterbury Road, Brixton in the County of
Surrey, Civil Engineer do hereby declare the nature of my Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF TELESCOPIC DRINKING VESSELS WITH
OR WITHOUT APPLIANCE FOR HEATING THE CONTENTS THEREOF," and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
This Invention has for its object to provide a drinking vessel of the so-called
telescopic shape-that is to say consisting of several parts sliding into one
another-being so constructed as not to close up again of its own accord when
opened and containing not only the alimentary substances to be drunk in a diluted
form out of such vessel, but likewise the fittings or appliances necessary for heating
the contents of the vessel; thus furnishing in the most compact shape which it is
possible to devise a vessel for holding beverages and the culinary means of heating
the same.
In the accompanying sheet of drawings I have shewn a telescopic drinking
vessel constructed according to my Invention, together with the appliances for
heating, the same. Figure 1 is a sectional elevation of the open vessel, with the
handle attached thereto, and with the heating appliance screwed thereon. Figure 2
is a sectional elevation of the same vessel, with the heating appliance screwed off,
the vessel proper resting upon a stand consisting of several legs fitted to the
beating appliance. Figure 3 is a longitudinal section of the same vessel closed up,
with the heating appliance screwed thereon, and comprising a casing or bottle
containing the alimentary substances to be prepared, as well as the handle for
holding the components of the vessel apart. Figure 4 represents a front and side
elevation of the handle alluded to. In all these views, identical letters of reference
denote identical parts of the apparatus constructed according to my Invention.
The drinking vessel proper as represented in the accompanying sheet of drawings,
consists of three component parts k, l, m, Figures 1 and 2, which, when closed up,
only take up the room of oue part. It is obvious that I do not limit myself to
any particular number of parts of which a drinking vessel constructed according to
my Invention may consist... The handle a is furnished at the top with a fork a¹
fitting upon a staple-shaped band c fixed to the upper part of the vessel and with
two legs a" a" enclosing such band laterally, whilst the lower part of the handle a

page_text: fits within another staple-shaped band c fixed to the lower part of the vessel, thus
holding the components of the vessel apart after the beverage has been prepared.
When the vessel is closed up, the handle a may be put inside, as shewn in Figure 3.
To the top d of the vessel the cup or casing e is fitted, within, which the coffee, tea,
cocoa, or any other substance of which a decoction is to be made, as well as the
alcohol or other suitable fuel may be kept, so that when the vessel is closed up,
none of the space within it may be wasted. The bottle or casing e may be screwed
up by means of the cap e', with a cork or in any other suitable manner.
The heating appliance f is so arranged that the lower part of the vessel may be
screwed into it, the two parts of the apparatus thus forming a compact body. The
casing I fill with incombustible cotton slag h h which absorbs alcohol or other
liquid fuel by percolation and which being lighted, beats the vessel proper. In
Figure 1 I have shewn the beating appliance screwed on, and in Figure 2 screwed
off the vessel proper. I cover over the heating appliance with wire gauze or
perforated metallic plate ii which, in conjunction with the porous nature of the
cotton slag h h,. prevents the liquid fuel from being spilled. To the heating
appliance the legs p p are fitted in such a manner by means of hinges that they
may be folded up, as shewn in Figures 1 and 3 when the apparatus is out of action,
or may be fixed up vertically and held up by means of a ring z, when the apparatus
is in action; and the base of the heating appliance f being much broader than that
of the vessel proper, prevents the latter from getting topheavy and being upset.
The legs pp when put upright may also be held apart by a spring being placed
between them or by any other suitable contrivance.
In those cases in which it is not intended that a telescopic drinking vessel
constructed according to my Invention should be used for culinary purposes, I omit
the cooking appliance as well as the casing or bottle e altogether. In that event
the lower part of the apparatus simply forms the foot or base of the drinking
vessel, the advantage of such an arrangement being that the foot may be readily
screwed off and every part of the entire apparatus be easily cleaned, which is not
possible in the ordinary kind of telescopic vessels.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The handle a for holding a telescopic vessel and preventing its component
parts from collapsing, in the manner described and shewn Figures 1, 3, 4 of the
accompanying sheet of drawings.
-
2. The staple-shaped bands b, c, at top and bottom of the vessel, for fitting
the handle as described and illustrated in Figures 1, 2 and 3 of the accompanying
sheet of drawings.
3. The casing e for holding the alimentary substances, fitted to the top of the 4
vessel d as shewn in Figure 3 of the accompanying sheet of drawings.
4. The use of screw-threads for. screwing the base f to the bottom of the
vessel m, in the manner shewn in Figures 1, 2 and 3 of the accompanying sheet of
drawings.
5. The folding legs p p in connection with a ring or a spring, as a stand for 4
the vessel to rest upon while the process of heating is going on, as illustrated in
Figures 1, 2 and 3 of the accompanying sheet of drawings.
Dated this 12th day of February 1884.
