PROVISIONAL SPECIFICATION.
Improvements in Urns suitable for retailing Hot Coffee and Milk
or other Hot Beverages.
I, ALBERT ETZENSBERGER, Manufacturer, of 6, Sheppey Avenue, Minories, in the
County of London, do hereby declare the nature of this invention to be as follows:-
This invention has for its primary object to provide simple and convenient
apparatus for retailing a mixture of hot water, coffee extract and milk, but is
applicable also to urns for retailing other hot beverages with a minimum of labour.
The apparatus chiefly comprises a water and milk heater provided near the top
with an annular gallery suitable for supporting cups and saucers; a tubular receptacle
for coffee extract placed parallel with the water heater and attached to the same, said
receptacle being made of glass and protected by a cylindrical casing of sheet metal
which has a vertical slot through which to observe the level of the liquid in the glass;
a two way tap connected with the water receptacle and with the extract receptacle,
and constructed in such a manner that by opening the tap, water and coffee-extract
are caused to flow out simultaneously in certain proportions which may be constant
or adjustable. Instead of water and another liquid, three different kinds of liquids
may be caused to flow out of their receptacle simultaneously by means of a three-way
cock.
The water receptacle is preferably bell-shaped, with a socket at the upper end for a
milk pot, which is inserted in the said socket and heated by the surrounding water.
The stand of the waterheater is formed by a downward continuation of the sides of
the bell-shaped water receptacle, which stand is high enough to contain a suitable
gas or other burner, and has perforations or slots for the admission of air. The water
receptacle is provided with a water gauge to indicate the level of the water in the
same. The circular gallery mentioned above is preferably made ornamental, and is
provided with fixed or detachable hooks for hanging up the cups, preferably double
hooks having the shape of an anchor, while the saucers are placed on the flat upper
surface of the gallery.

Improvements in Urns suitable for retailing Hot Coffee and Milk
or other Hot Beverages.
I, ALBERT ETZENSBERGER, Manufacturer, of 3, Sheppey Avenue, Minories, in
the County of London, do hereby declare the nature of this invention and in what

page_text: 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 simple and convenient apparatus for
retailing a mixture of hot water, coffee-extract and milk, but is applicable also to
urns for retailing other hot beverages, with a minimum of labour.
The apparatus chiefly comprises a water and milk heater, which may be provided
with an annular gallery suitable for supporting cups and saucers; a tubular receptacle
for coffee extract placed parallel with the water heater and attached to the same, said
receptacle being made of glass and protected by a cylindrical casing of sheet metal, which
has a pair of vertical slots, through which to observe the level of the liquid in the glass,
and a two way tap connected with the water receptacle and with the extract receptacle
and constructed in such a manner that by opening the tap water and coffee extract
are caused to flow out simultaneously in certain proportions which may be constant
or adjustable. Instead of water and another liquid, three different kinds of liquids
may be caused to flow out of their respective receptacles simultaneously by means of a
three-way tap.
In the accompanying drawings,
Fig. 1 is a side elevation of a coffee urn embodying my invention;
Fig. 2 is a front elevation of the extract receptacle and two-way tap:
Fig. 3 shows the extract receptacle separately;
Fig. 4 is a plan of the two-way tap on a larger scale; Figs. 5 and 6 are sections
of the same, and Fig. 7 is an end view of the core d.
A is the water receptacle and heater, B the glass tube containing the coffee-extract,
C the sheet-metal casing enclosing the the same, and D the two-way tap.
The glass-tube B is closed at the top by a plug b, and connected at the bottom
with a metallic supply-tube E by means of an india rubber sleeve e. The tube E
communicates at the lower end with the two-way tap D and contains a small tap e for
regulating the quantity of liquid coffee extract admitted to the tap D.
The core d of the tap D has two perforations, one of which communicates on the
inlet-side with the hot-water supply pipe d,, and the other with the pipe E, while on
the outlet side both perforations communicate with the discharge and mixing tube d³,
provided that the handle F has been turned into the opening position. If the
handle F is turned back about 90 degrees, the core of the tap D closes the tubes d'
and E.
The casing C which protects the glass tube B is attached to the side of the water
heater A by means of a bracket or arın b, and closed at the top by a detachable cover H.
b, b, are a pair of longitudinal slots placed diametrically opposite each other, so as to
show the level of the liquid in the glass tube B.
The water receptacle is preferably bell-shaped, with a socket a at the upper end
for a milk-pot I which is inserted in the said socket and heated by the surrounding
water. The stand K of the water heater is formed by a downward continuation of
the sides of the bell shaped receptacle, it is high enough to contain a suitable gas or
other burner and has perforations or slots k for the admission of air. The water
receptacle is provided with a water gauge L to indicate the level of the water in the
same. a is the annular gallery mentioned above. It is provided with anchor shaped
hooks M to hang up the cups, while the saucers are placed on the flat upper surface
of the gallery.
Instead of making the tube B of glass, porcelain or other suitable material may be
used, and the slots & in the casing C may be omitted. The heater A may have any
convenient shape, with or without a gallery a'.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. In coffee-urns or apparatus for retailing hot beverages, the combination of a
water heater with a glass-tube containing coffee-extract or other suitable liquid and
provided with an outlet tap, said glass tube being secured to the side of the water

page_text: heater and protected by a longitudinally sloted metal casing, substantially as described
and for the purpose specified.
2. In coffee-urns or apparatus for retailing hot beverages, the combination of a
water heater, with a receptacle for coffee-extract or other suitable liquid secured to
the side of the water heater, and a two-way tap communicating on one side with the
water-heater and the extract-receptacle by separate passages, while the opposite side
communicates with a single outlet, substantially as described and for the purpose
specified.
