A NEW OR IMPROVED APPARATUS FOR MEASURING WATER OR OTHER LIQUIDS
Year: 1875

page_text: LETTERS PATENT to Henri Adrien Bonneville, of the British and
Foreign Patent Offices, 18, Rue de la Chaussée d'Antin, Paris,
France, and 6, Piccadilly, in the County of Middlesex, Patent
Agent, for the Invention of "A NEW OR IMPROVED APPARATUS FOR
MEASURING WATER OR OTHER LIQUIDS."-A. communication from
Lætitia Alexandrine Pascal, Widow of Mr. François Herbepin,
residing at No. 21, Rue du Grand-Prieuré, Paris, France, afore-
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 16th November 1875, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 18,
Rue de la Chaussée d'Antin, Paris, France, and 6, Piccadilly, in the
County of Middlesex, Patent Agent, send greeting.

page_text: between the ends of the two arms of which is carried a small shaft m, on
which are mounted three moveable rollers. These rollers are placed
between two flat parallel springs n, n, having on their inner face the
one a central shoulder o, over which slides one of the rollers, namely,
the central one, the other two side shoulders p, over which the other two
side rollers slide; these shoulders are inclined on each face, the chape
arms undergoing an alternate rocking motion, the rollers which they
carry are also brought to bear alternately upon the inclined and opposed
faces of the shoulders o and p, and impart a reciprocating motion to the
two flat springs until an unlatching takes place by the alternate passage
of the rollers over and on the other face of the shoulders.
The ends of the two flat springs are linked to cranks q fastened to the
outer ends of two short shafts r, which pass water-tight through the side
of a box s, in which their other end is provided with an arm t, the end
of which passes through and plays into a slide at the free end of the
rod u of the double valve c; this constitutes one of the main parts of the
Invention. The alternate reciprocating motion of the two flat springs n
is thus transmitted through the cranks q to each shaft r, to which an
alternate partial rotatory motion is imparted, which is transmitted by
the arm t with which it is provided in rectilineal motion to the rod u of
the valve c which permit or intercept each in turn the flowing of the
liquid as herein-after explained.
The inlet pipe d like the outlet pipe e is subdivided into two branches
v, x, which meet in the pump barrel 6 at its two extremities. One of
the double valves c closes alternately each inlet pipe branch v, whilst the
other closes alternately, but in an opposite sense, the two outlet pipe
branches x; the liquid is brought then into the pump barrel 6 by each
of its ends alternately to act and press on one of the faces of the
piston a, whilst it is forced back alternately by the other face of the
piston into one of the branches x of the outlet pipe e. There exists
then no intermission in the flowing of the liquid, and the pressure is the
same at the inlet and at the outlet.
To measure the quantity of liquid flowed out, a quantity equal to the
capacity previously gauged of the pump barrel b, the chape above
mentioned carries linked on its inner branch the cranked arm y of a
catch, the free end of which acts by forcing it back at each return
oscillatory motion of this chape on a ratchet wheel mounted to the

page_text: end of the shaft w which operates the gearing of the registering dials
generally used.
Having thus described the nature of the said Invention and the
manner of carrying it into effect, I would have it understood that I do
not confine myself to the precise details above enumerated, as these
may obviously be modified without departing from the principle of the
Invention, but what I claim is the combination of a driving piston
working in a cylinder or pump barrel under the action of the liquid,
and acting on two double rod valves moving alternately in the inlet
and outlet pipes, substantially as above described and illustrated in the :
accompanying Drawings.
.
In witness whereof, I, the said Henri Adrien Bonneville, have here-
to set my hand and seal, this Twelfth day of November, in
the year of our Lord One thousand eight hundred and seventy-
five.
