EMILE JAPY, of Boulevard Saint Denis, No. 1, at Paris, Manufacturer. AN
IMPROVED COCK INTENDED FOR THE COMPUTATION OF GLASSES OF BEER, WINE,
OR OTHER BEVERAGES OR LIQUIDS IN BREWERIES, COFFEE HOUSES, PUBLIC HOUSES,
AND SIMILAR PLACES, AND APPARATUS IN CONNECTION THEREWITH."
A com-
munication by Constant Daillier, of Boulevard St. Denis, 1, at Paris.
The object of this Invention is to prevent the loss and waste which at present
takes place daily in the retailing of liquids or beverages, arising either from the
fraud or carelessness of the servants or dispensers.
The apparatus which can be placed on the counter or in any desired position only
allows a single glass to be filled at a time and at once registered on a dial.
The apparatus consists of two distinct elements, one being an improved arrange-
ment of cock or tap in combination with a measuring recipient.
The cock consists of a tubular plug having four orifices, two at the upper part of
the plug and two at the bottom, the two first corresponding one after the other
with the delivery pipe or passage, and one of the others with the plug, and the last
with the supply, the two lower orifices being separated from each other by a
partition. These lower orifices communicate with holes in the barrel, and with
india-rubber or metal pipes connected to both ends of the measuring recipient in
which works freely a piston valve having at each end an elastic washer used to
close alternately the openings at the ends of the measuring recipient, the cubical
contents of which exactly corresponds with the contents of a glass of beer or other
liquid which is let into a a glass or other receptacle by turning the handle of the
cock, which is turned in one direction for one glass, and the reverse direction for
another glass, and so on alternately.

page_text: When the contents of the recipient is let off it is immediately filled with another,
and not a single drop is supplied more than is intended. And for registering the
number of glasses filled or supplied I fix to the plug of the cock a toothed wheel
gearing into a toothed segment which works any suitable arrangement of clock-
work or measuring wheels in connection with a dial and fingers, the key of the case
containing the clockwork being kept by the employer or supervisor.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Emile Japy in the Great Seal Patent Office on the 16th September
1876.
EMILE JAPY, of Boulevard Saint Denis, 1, at Paris, Manufacturer. "AN IMPROVED
COCK INTENDED FOR THE COMPUTATION OF GLASSES OF BEER, WINE, OR OTHER
BEVERAGES OR LIQUIDS IN BREWERIES, COFFEE HOUSES, PUBLIC HOUSES, AND
SIMILAR PLACES, AND APPARATUS IN CONNECTION THEREWITH." A communication
by Constant Daillier, of Boulevard St. Denis, 1, at Paris.
The improved tap which forms the subject of my Invention has for object to
prevent the loss and waste which takes place daily in the retailing of liquids or
beverages, arising either from the fraud or carelessness of the servants or dispensers.
The apparatus which can be placed on the counter or ordinary beer engine
only allows of a single glass being drawn at a time, which immediately registers
on a dial the drawing off of the glass of liquid. In this manner the proprietors
at all times of the day can see what has been sold, and at night has an absolute
check on the takings since the last inspection.
The construction and working of the improved apparatus will be well understood
by referring to the annexed Drawing.
Fig. 1 is a front view of the apparatus in position and attached to the supply
pipe; Fig. 2, a side view; and Figs. 3, 4, and 5 are views of detached parts for
further illustration of the following particular description.
The apparatus consists of two distinct elements, being the tap proper in com-
bination with a measuring reservoir furnished with a piston valve, and the
registering mechanism which indicates on the dial each action of the tap.
The tap consists of a tubular plug a, Fig. 3, having four coupled openings 6, 6¹,
c, c¹; the two first b, b', at the outer end of the plug correspond directly and one
after the other with the outlet d of the tap; the other two openings are arranged
in a horizontal plane, they correspond respectively the one c with the end f of the
plug a, and next with the conduct tube g which supplys the liquid under pressure,
and the other c¹ is in direct communication with the body of the plug a for con-
ducting the liquid passing therethrough to the opening b or b¹ communicating with
the outlet d; the two openings c, c¹, are separated by an oblique midfeather c².
Communicating with the openings c, c¹, are two (india-rubber or metal) pipes h, h³,
fixed to the rear part of the tap, and which are respectively attached to the ends of
the measuring reservoir R, Fig. 4, in which reservoir a piston valve work freely,
and is furnished at each end with an elastic boss 2, ¹, for the purpose of alternately
opening and closing the ends of the two conduit pipes h, h¹, this reservoir with its
piston being constructed to exactly hold a quantity equal to the contents of a glass;
for beer, for example, this will be that of an ordinary tankard.
From the described arrangement it will be seen that on a half turn of the
handle M of the tap the liquid contained in the reservoir R is drawn off at the
outlet d, and another quantity of liquor replaces on the other side of the piston i
that which is drawn off, said piston thus alternately playing from one side to the
other of the reservoir R, but there only escapes from the outlet d at each turn of
the handle the contents of the reservoir R and not a drop more. To draw off more
liquor the handle M is reversed and another glass or quantity will be indicated on
the dial K.

page_text: The working of this dial is effected in the following manner :-The rod j of the
handle M carries a toothed segment plate k which gears with another toothed
segment keyed to a small shaft parallel to the nozzle of the tap, said shaft l
carrying a finger m (or a cam piece) which describes a half revolution, indicated at
x, Fig. 5, at each turn of the tap. At the middle of its course the finger m raises
a swing lever n pivoted at n', which lever on falling actuates the ratchet wheel n²
moving it one tooth around by means of the spring catch o working in connection
with the stop catches o¹, o²; the movement of the ratchet wheel n³ is transmitted
through the count wheels p, p¹, p³, p³, p*, the diameters of which are arranged in
such wise that the wheel of the large pointer or hand q advances ten teeth, while
that of the small hand r advances but one division, which thus indicates on the
dial K the units and decimals of glasses sold.
The box D which encloses the dial K is locked and the key kept by the proprietor
or authorized person so that no one can touch the hands, and at the close of the day
the accounts can be checked with facility. The apparatus is set at zero by simply
turning the hands.
Having now described the nature and particulars of the said Invention I claim
the improved tap for the computation of glasses of liquid substantially as herein
described and shown in the Drawing hereunto annexed and marked by the following
principal features, viz :-
1st. The special combination of the tap with the measuring reservoir.
2nd. The plug a of the tap substantially as described and shown.
3rd. The measuring reservoir with its free piston, valve, and supply pipes
arranged and working substantially as set forth.
4th. The registering mechanism for actuating the hands on the dial.
5th. The general arrangement and combination of the apparatus substantially as
herein described and shown by the Drawings.
In witness whereof, I, the said Emile Japy, have hereunto set my hand and
seal, this Seventh day of September, in the year of our Lord One thousand
eight hundred and seventy-six.
