PROVISIONAL SPECIFICATION.
Improvements in Tea, Coffee, and Cocoa. Urns.
ROBERT LOXнAм Tea. Merchant 1 Nicholas Street Colne Lancashire do.
hereby declare the nature of this invention to be as follows :-
It consists of an oblong boiler heated with a gas jet at the bottom just on the:
same principle as an ordinary tea urn, but is used for boiling water only.
In the inside near the top there is a cold water tap worked by a floating ball
so as to be self feeding.
On the front side there is three taps, one for tea, one for coffee, and one for
cocoa.
On the outlet-side of the plug in each tap there is a small pipe connected
which extends upwards about four inches, at the top of this there is a small tap,.
and connected to the top of this tap is a small round cistern which contains cold tea.
brewed very strong or what may be termed tea essence.
The tap attached to the cistern and the draw tap at the bottom is connected by
means of a small connecting rod from the handle of one tap to the handle of the:
other.
The draw tap at the bottom is the one to be used which is about ten times the
size of the other, and by pulling this handle both taps are turned at the same time
and will draw from both sources at the rate of about ten of water to one of
essence through the same outlet tap.
This declaration applies exactly the same both to tea, coffee, and cocoa.
The main feature in this invention is to produce a fresh cup of tea for every
customer, and totaly abolish stewed tea.

COMPLETE SPECIFICATION.
Improvements in Tea, Coffee, and Cocoa Ṭrns.
I, ROBERT LOXHAM, 1, Nicholas Street, Colne, in the County of Lancaster,.
Tea Merchant, 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 urns for making or preparing tea, coffee, or cocoa, more
especially for use in restaurants, railway stations, hotels and other places where.
these beverages are sold for public consumption.
The body of the urn is of the usual construction, but is for supplying hot water
only, and consists of a strong oblong boiler, heated with a gas jet at the bottom,.
just on the same principle as tea urns in common use. It may be fitted with a cold
water supply tap regulated by a ball float, so as to be self feeding, and maintain
the water in the cistern or urn as near as possible at one level.
It will now proceed to describe the novel features of my invention. In front of
the urn may be arranged, one, two or three taps for tea, coffee or cocoa respectively,
it being evident that where only one of these beverages is required the urn needs.
only to be fitted with one draw-tap. Immediately above each draw-tap, and fixed

page_text: to the urn in front is a small cistern or receiver, which contains a very strong
decoction or essence of tea, coffee or cocoa. From this cistern or receiver proceeds
a small pipe connection, which communicates with the draw tap on the outlet side
of the plug, and at the top of this pipe I provide a small tap about one tenth the
size of the draw tap plug; the handles of both plugs being connected together by
a connecting link or rod, so that both taps are opened and closed simultaneously.
In the accompanying drawings,
Fig. 1 is a front view, and
Fig. 2 a side view of an urn with my invention applied.
Referring to Fig. 2, A is the urn or hot water boiler, which may be provided
with gas jet for heating purposes, and ball tap for regulating cold water feed, as
already described and well understood. B is the draw tap provided with handle C
for opening plug of draw tap, and drawing hot water from the boiler A. Arranged
above the said draw tap is small cistern or receiver D having lid E at the top. At
the bottom of the cistern or receiver D is a small plug valve or tap F, and
communicating with these and the outlet side of the draw tap is a small tube G.
Fixed to the plug of the valve F is a small lever H, which is connected to the
handle C of the draw tap by connecting link or rod I so that on operation of said
handle C both taps will be opened and closed at the same time.
In the receiver or cistern D is poured a very strong decoction or essence of cold
tea, coffee or cocoa, which always remains cold until it comes in contact with the
hot or boiling water issuing from the draw tap on the operation of the handle C.
It is very advantageous to have the small tube connection G communicating
with the outlet side of the tap B, for then no essence ever becomes lodged in such
tube connection. It is palpable that if on the contrary the essence were so allowed
to stagnate for any significant length of time, the succeeding draught or cup would
be exceedingly impaired in flavour through stewing; since the tube connection G
is in direct metallic contact with the hot draw tap, and is in the immediate presence
of the hot water boiler itself.
The plugs of the two respective taps or valves are preferably in such relation to
one another, that ten parts of hot water will be emitted from draw tap B in
proportion to one of essence through valve or tap F.
In Fig. 1 is illustrated the urn A provided with three cisterns D and the same
number of draw taps B with their auxiliaries for supplying tea, coffee or cocoa
respectively. The arrangement of these cisterns and connections is exactly as that
described in relation to Fig. 2. The cistern or cisterns D may be provided with a
removable gauze sieve near the top to intercept tea leaves, grains or sediment,
which may be inadvertently poured with the essence therein. In some cases,
I employ a separate and independent hot water tap in connection with the urn for
supplying hot water only.
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. The improved construction and arrangement of apparatus for intermixing tea,
coffee, or cocoa essence with hot water, substantially as described and illustrated in
Figs. 1 and 2.
2. Tube connection G fitted on outlet side of draw-tap B, connecting link or
rod I, and means for operating taps B and F simultaneously, substantially as
described and illustrated for the purpose set forth.
