BEVERAGE COOLING AND DISPENSING BAR
Gligor Christa, Rochester, N. Y.
Application July 29, 1936, Serial No. 93,140
10 Claims. (Cl. 225-1)
My present invention relates to the dispensing
of beverages and more particularly to coolers,
oler pressure, preferably enters a coil at the top
and its course is helically downward to, an in
such as are used in serving draft beer, and it has
for its object to provide a cooler of this nature
and incorporate it in the structure of a service
bar with such effect that a patron of the bar
may see the beverage as it is drawn through the
coil and‘ before it reaches the tap and the glass to
ward and centrally upward extension. l3 of the
glass tubing within the coil, which extension,
through suitable ?ttings in the rear of the casing 5
be later served to him. A further object of the
10 invention is to provide a series of coils for the
dispensing of a plurality of brands of beverages
in combination with means for visibly indicating
the particular brand that is being drawn in re
sponse to the customer’s order.
15
To these and other ends, the invention resides
in certain improvements and combinations of
parts, all as will be hereinafter more fully de
scribed, the novel features being pointed out in
the claims at the end of this speci?cation.
In the drawings:
20
Fig. 1 is a front perspective view of a service
bar or fountain constructed in accordance with
and illustrating one embodiment of my invention;
Fig. 2 is an enlarged vertical section taken
25 through the cooler section of the bar,
Fig. 3 is a relatively transverse vertical longi
tudinal section through the same somewhat re
duced from the scale of Fig. 2.
Similar reference numerals throughout the
several views indicate the same parts.
Referring more particularly to the drawings,
3, leads to the faucet or tap: I it above the drip tray
E5 in the usual manner. The chamber or tank 4
is ?lled with water that submerges and surrounds
the coils and which is cooled to the proper tem
perature by a refrigerating unit it at the rear 10
also submerged in the water. The usual piping
ll connects the unit 56 with the radiator E8 in
lower chamber 6 for bringing down the tempera
ture of the refrigerating ?uid and the radiator
in turn is connected by appropriate piping I9 15
with the compressor 28. This compressor is
driven through a pulley 2i and belt 22 from a
motor 23 (shown in dotted lines in Fig. 3) on the
shaft of which is a fan or blower 24 associated
with the radiator W for drawing air against the 20
same.
The source of energy for the motor is
shown through the connection 25 to the outlet 26.
There is the usual thermostatic control, not
shown, and, indeed, the whole refrigerating set
up as such is represented somewhat convention- 25
ally as typical of this type of apparatus and will
be understood as far as it forms a part of this
invention by those skilled in the art.
The ventilating chamber 5 before referred to
may be formed of suitable general and special 30
casing parts, such as an auxiliary shell or casing
l indicates a bar or a fountain ?xture that may
21 at the top of which are air inlet openings 28.
be, in general, of any known type having an upper
counter or service surface 2. Preferably in the
panel 29 opposite and spaced from the front wall
35 center thereof is an intermediate cooling section,
indicated generally at 3, which numeral also
designates the general casing or shell thereof.
The top of this section is continuous with the
surface 2 and used for the same purpose. Within
the casing 3 are three chambers, namely, an up
per cooling chamber 13, a ventilating chamber 5
forwardly thereof and a radiating and compress
ing chamber 6 beneath.
The cooling chamber is preferably constituted
45 by an integral glass tank 1, the front wall ‘IiL of
which is forwardly exposed to view and the top»
wall of which consists of a lid 8 flush with the
top of the section and with surface 2. In this
tank are arranged a row of glass cooling coils 9.
Each one of these, through a union l0 and suit
able ?ttings, is connected by a pipe H (running
usually down through the floor l2) to the bever
age source such as a keg of beer in the cellar.
The beer, which we will adhere to as being the
55 beverage for the purposes of this description, un
t is also provided with a. glass front wall or
is of cooling chamber 4 so that, through both of 35
these walls as well as through the top 8 of-the
latter, the coils 9 may be viewed at all times by
the patrons of the bar.
The result is that even the uninitiated can in
stantly note which one of the taps M is being used 40
and through which coil beer that is being drawn
is passing, and hence which brand is being served
as will hereinafter appear. This, in general, is
because the beer as it comes from the keg under
gas or air pressure inherently contains enough 45
bubbles to reveal the fact that it is surging down
through the coils, whereas the beer temporarily
standing in the unused coils will have freed itself
of bubbles which will have risen out of view. I
prefer to construct the coils 9 of clear glass, but 50
other light transmitting materials that will re
?ect the bubbles, such as frosted glass, will give
the eifect though less de?nitely.
Returning to the ventilating chamber 5, this
communicates at its bottom at 36 with the radi- 55>
2
2,118,724
ator chamber 6 and preferably in general aline
ment with the radiator l8 below-it and behind
which the blower is arranged as aforesaid. The
bene?cial result ?owing from this is two-fold,
namely, the blower indirectly draws air through
the openings 28 and downwardly through cham
ber 5 in a continuous ?lm across the walls '!a and
29, thereby preventing these walls from frosting
(particularly, the refrigerating wall 1*‘) and in
10 terfering with a clear view of the interior of
chamber 4.
Also, this air is thereby cooled and
is the same air that is drawn through or across
the radiator l8 of the compressor unit, which
makes it act more e?'iciently in lowering the tem
15 perature of the gas.
In other words, in non
technical language, the cold that is radiated and
which escapes from the tank wall ‘Ia is utilized
again at its source to cool the compressed gas.
As a further means of identifying the particu
20 lar coil 9 through which the beer is being drawn,
I provide means for illuminating that coil indi
vidually and automatically through the manipu
lation of the corresponding tap M.
This con
sists, in the present instance, of a neon or vapor
25 electric lamp tube 3| associated with each coil.
and thus stale beer is not left in the coil and
practically no beer is wasted through the empty
ing of that keg and the tapping of a fresh one.
I claim as my invention:
1. A beverage bar having an intermediate cool
ing section an upper plane portion of which con
stitutes an uninterrupted ?at horizontal part of a
continuous upper service surface, said cooling
section embodying a water tank located entirely
below the latter in combination with a beverage 10
coil of light transmitting material in the section,
a tap at the rear thereof drawing from the coil,
and a beverage source leading to the latter, said
section being provided with a transparent wall
located so as to expose the coil to the view of a 15
patron of the bar.
2. A beverage bar having an intermediate cool
ing section an upper plane portion of which con
stitutes an uninterrupted ?at horizontal part of
a continuous upper service surface, said cooling 20
section embodying a water tank located entirely
below the latter in combination with a beverage
coil of light transmitting material in the section,
a tap at the rear thereof drawing from the coil,
and a beverage source leading to the latter, said
Its lead wires 32 plugged in at 33 to the outlet
section being provided with transparent top and
26'include a switch or circuit breaker, indicated
generally at 34 in Fig. 2. This may be in the
form of an ordinary push button construction
30 35, except that it is the reverse of a bell button
in that, when the spring pressed button is nor
front walls to expose the coil to the view of a
mally out, the circuit through the lamp is closed
and when it is pressed in the circuit is held
broken. When the handle 36 of the tap I4 is
35 in inoperative or closed position, as in Fig. 2,
a ?nger 3'! thereon holds button 35 depressed
and hence the lamp 3| of this circuit is dead.
When, however, the handle is drawn forwardly
to open the tap and draw the beer, the button
is released, the circuit is closed and the lamp
is charged.
In addition to all of the foregoing provisions,
I have provided further means for indicating the
brand of beer that is being drawn, which also
45 acts as an advertising device for that brand.
It consists, in the present instance, of a verti
cally disposed tablet 38 associated with each coil,
on which the name of the brand appears and is
readable through the transparent media that sur
round it. It may occupy the center of the coil
and be held to the central discharge stem l3
thereof by a suitable clip 39 or in any desired
manner. When the coil illuminating circuit of
that particular tap is closed, the tablet is illumi
55 nated also and provides a reading of the selected
brand. This may be enlarged as an advertising
feature and many variations of the principle in
troduced, as, for instance, neutralizing combina
tions of colors may be employed in the neon tube
60 3| on the one brand and the individual coil tab
lets 38 or the lettering thereon on the other,
so that the reading will not be visible by natural
light or normally, but only through the re?ec
tion of the lamp color.
65
For the sake of cleanliness, as well as to carry
out the expressed features of my invention, I
prefer to make the entire line of draft from keg
to tap, except for necessary metal connections, of
clear glass. The coils rest in glass seats 40 in
70 the bottom of tank or chamber 4 and, due to the
fact that the beer enters the coil from the top
convolution and leads direct to the tap from the
bottom convolution of the coil, when the keg or
barrel “blows”, as it is called, the inrushing free
75 _ pressure gas will almost completely clear the coil,
patron of the bar.
