"
WHEREAS I am in possession of an Invention for "NEW OR IM-
PROVED APPARATUS FOR MEASURING AND REGISTERING THE FLOW OF LIQUIDS,'
a communication from Jean Joseph Barretto and Antoine Joaquim
Barretto, two persons resident at Lisbon, in the Kingdom of Portugal,
Merchants, and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for
the same, and made solemn Declaration that it is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification, under my hand and
scal, fully describes and ascertains the nature of the Invention, and
the manner in which the same is to be performed, reference being had
to the accompanying Drawings:-
The Invention communicated to me relates to an apparatus for
measuring with accuracy the flow of liquids, and particularly the water
appropriated for public and private purposes. It may be peculiarly
adapted to the measuring of the waters, on their flowing into or out of
aqueducts, reservoirs, ponds, public buildings, factories, bath houses,
and other such like private establishments. By varying the shape and
the size of this apparatus it may be made to ornament private habitations.
The said apparatus is represented in the accompanying Drawings, of
which Fig. 1 is an elevation; Fig. 2, a plan; Fig. 3, a vertical section
by the line A, B, Fig. 2, and Fig. 4, a vertical section by the line C, D,
Fig. 2. Like letters of reference indicate corresponding parts through-
out these Figures.
a is a nozzle furnished with a perforated cap or plate for intercepting
the passage of all foreign matters carried away by the liquid. This
nozzle joints on to a branching pipe in communication with the main
feed pipe; b is a pipe extending through the reservoir c and conveying
the liquid to the double water cock d, which allows of intercepting or of
establishing communication with the column e; f is an oscillating pipe
in communication with the column e effusing alternatively the liquid
into the two receptacles g, g³, placed on the lid or cover of the reservoir;
h, h', are valves disposed at the bottom of these receptacles for the
outflow of the liquid into the reservoir. These valves are connected
with hollow spheres i and at their lower portion, which are themselves

page_text: connected at their upper portion with the extremities of the oscillating
pipe by means of a rod; j is a metallic or glass envelope. The liquid
when poured into one of the receptacles 9 or g¹, into g for instance,
gradually rises to a certain height representing a given quantity of
liquid, the sphere i being afloat rises also and uplifts by means of its rod
the extremity of the pipe f, which then topples over and pours the
liquid into the other receptacle g', whilst the valve uplifted by the
sphere affords passage to the measured liquid, which flows into the
reservoir. The liquid in the reservoir then runs out by the lower
portion of the cock d, which on being turned on replenishes with
liquid the receptacles 9 and g¹, whilst that contained in the reservoir
is allowed to flow out. A hollow sphere l, placed inside the reservoir c,
is connected with a valve m disposed in the ascensional column e, and
which in the event of the apparatus getting out of order intercepts the
arrival of the liquid by the column e. The oscillating pipe f is con-
nected by its fulcrum on the one hand with a balance furnished with
a mercurial tube or a pendulum which facilitates the oscillation, and
on the other hand with an escapement wheel o, imparting by means
of intermediary gearing motion to hands which register during an
indefinite length of time on a dial carrying divisions the quantity of
liquid having flowed through. When the apparatus is adapted so as to
give out liquids by several orifices the system of floating cock ? placed
in the pipe 6 extending through the reservoir and into the column e
should be used.
From the foregoing explanations it will be seen that the automatic
motion of the apparatus depends entirely on the opening and closing of
the cock d which allows or intercepts the introduction of the liquid into
the reservoir by the column e, the oscillating pipe f, the receptacles
9, g', and the valves h, h, and its effusion from the reservoir by the
lower orifice d².
Having now fully described and ascertained the nature of the said
Invention, and the manner of carrying the same into effect, I would
have it to be clearly understood that I do not confine myself to the exact
details above enumerated, as these may obviously be modified without
departing from the principle of the said Invention, but what I claim
is, the oscillating pipe f, the hollow spheres i, ¹, and 1, the valves h, h²,
and m, and their combination together, and with the cock d, d', the

page_text: receptacles g, g¹, and the wheel o, substantially as herein-before fully
set forth and described and illustrated in the accompanying Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereunto set my hand and seal, this Thirtieth day of April,
in the year of our Lord One thousand eight hundred and sixty-
