NEW WATER METER, APPLICABLE ALSO FOR MEASURING OTHER LIQUIDS."
"A
The aim of this meter is to incasure accurately the quantity of water or of any
other liquid running from a cock, whatever the variable. pressure of the column of
liquid may be.
The mechanism of this meter is enclosed in a tin box (A, A, A, A, Fig. 1 of the
accompanying Drawing) on one side of which are the indicating dials; the hands
move on the dials through the action of the prime mover of the wheel B (Fig. 1).
The liquid comes into the box by the tube C (Fig. 1), and goes out of it by tho
tube D (Fig. 1) after having passed through the mechanism, causing the hands to
indicate on the different dials the accurate quantity of liquid which has flowed
from the tube C in the following manner- -From the tube C.the liquid falls into
a recipient E (Fig. 1, 2, or 4), in which the pressure of the column breaks itself.
then it goes through an aperture C' (Fig. 1, 2, or 4) alternately into the reservoirs
(six, for instance, 1, 2, 3, 4, 5, 6, Fig. 4) of a small wheel with ladles (F, Fig. 1,
and 1, 2, 3, 4, 5, 6, Fig. 4) which is fixed to a larger wheel G (Fig. 1), both wheels
having the same shaft H (Fig. 1). The larger wheel has as many buckets as the
smaller one has reservoirs; the buckets are partly circular (I', 12, 13, 14, 15, 1º, Fig. 2),
and they respectively correspond with the reservoirs of the smaller wheel F (Fig. 1)
by means of apertures K (Fig. 2 and 4) made near the shaft (H, Fig. 1). The
apertures allow the liquid to pass from the reservoirs of the smaller wheel F
(Fig. 1) into the buckets of the larger one; the passage thus no longer taking place
at the upper part of the buckets, as it is the case in ordinary wheels, but at their
lower part near the shaft. Each of the buckets has another aperture X (Fig. 3)
through which the liquid goes out of them; hence it follows that the larger wheel
is supplied through the medium of the smaller one. On glancing at Fig. 3 and 5

page_text: the arrow of Fig. 3 showing the direction of the movement of the wheel, it will be
easily seen that each of the buckets empties itself gradually and becomes quite
empty when the issue X is at the lowest portion of the circular part, that is to say,
when the bucket is at the upper part of the wheel; then, being quite empty, it is
ready to receive again another portion of liquid from its corresponding reservoir of
the other wheel. The other buckets retain more or less liquid, according to their
positions and on account of their peculiar construction; this liquid maintains, so to
say, the wheel in equilibrium, and it turns only when the empty bucket is filled
(see Fig. 3, 4, and 5). The dials are of course to be divided and figured according
to the results given by the capacity of the buckets of the meter, which may be
constructed of all sizes. The liquid falls from the apertures of the circular part of
the buckets on the bottom of the tin box, passing by the tube D to the service cock.
To sum up, the dispositions of the new liquid meter consist in a recipient which
might be termed "pressure breaker," from which the liquid passes into the
reservoirs of an intermediary wheel, which in their turn transmit it into the buckets
of a larger wheel to which the smaller is fixed, the entrance of the liquid taking
place in the latter case near the common shaft of the wheels, and the buckets of
the larger wheel being constructed so as to discharge gradually their liquid and so
as to be emptied entirely when they arrive at the highest point of their rotatory
motion.

the said Auguste Malfroy in the Great Seal Patent Office on the 1st September

AUGUSTE MALFROY, of Horsley Road, Rochester, in the County of Kent. " A
NEW WATER METER, APPLICABLE ALSO FOR MEASURING OTHER LIQUIDS." A com-
munication from abroad by François Payre, junior, Mechanician, of Saint-Etienne,
Loire, France.
The aim of this meter is to measure accurately the quantity of water or of any
other liquid running from a cock, whatever the variable pressure of the column of
liquid may be. Hence it follows that it can be situated at any distance from the
place where the liquid originates without causing any alteration in the accurateness
of the measuring of the said liquid.
The mechanism is enclosed in a tin box A, A, A, A (Fig. 1 of the accompanying
Drawing), on one side of which are the indicating dials; the hands move on the
dials through the action of the rotatory motion of the shaft H (Fig. 1). The liquid
comes into the box by the tube C (Fig. 1) and goes out of it by the tube D
(Fig. 1) after having passed through the mechanism, causing the hands to indicate
on the different dials placed in L (Fig. 1) the accurate quantity of liquid which has
flowed from the tube C in the following manner-From the tube C the liquid
falls into a recipient E (Fig. 1, 2, or 4) in which the pressure of the column breaks
itself; then it goes through an aperture C¹ (Fig. 1, 2, or 4) alternately into the
reservoirs (six, for instance, 1, 2, 3, 4, 5, 6, Fig. 2) of a small wheel with ladles F
(Fig. 1) and 1, 2, 3, 4, 5, 6 (Fig. 4), which is fixed to a larger wheel G (Fig. 1),
both wheels having the same shaft H (Fig. I.). The larger wheel has as many
buckets as the smaller one has reservoirs; the buckets are partly circular, I', I², I³,
I, 1, 1, (Fig. 2), and they respectively correspond with the reservoirs of the smaller
wheel F (Fig. 1) by means of apertures K (Fig. 2 and 4) made near the shaft H
(Fig. 1). These apertures allow the liquid to pass from the reservoirs of the smaller
wheel into the buckets of the larger one G; the passage thus no longer taking
place at the upper part of the buckets, as it is the case in ordinary wheels, but at
their lower part near the shaft. Each of the buckets has another aperture X
(Fig. 3), through which the liquid goes out of them; hence it follows that the larger
wheel is supplied through the medium of the smaller one. On glancing at Fig. 3

page_text: and Fig. 5, the arrow of Fig. 3 indicating the direction of the movement of the
wheel, it will be easily seen that each of the buckets empties itself gradually and
becomes quite empty when the issue X is at the lowest portion of the circular part,
that is to say, when the bucket is at the upper part of the wheel; then, being quite
empty, it is ready to receive again another portion of liquid from its corresponding
reservoir of the other wheel. The other buckets retain more or less liquid, according
to their positions, and on account of their peculiar construction this liquid
maintains, so to say, the wheel in equilibrium and it turns only when the empty
bucket is filled (see Fig. 3, 4, 5). The dials are of course to be divided and figured
according to the results given by the capacity of the buckets of the ineter, which
may be constructed of all sizes. The liquid falls from the apertures of the circular
part of the buckets on the bottom of the tin box, passing by the tube D to the
service cock.
To sum up, the disposition of the new liquid meter consists in a recipient which
may be termed "pressure breaker," from which the liquid passes into the reservoirs
of an intermediary wheel, which in their turn transmit it into the buckets of a
larger wheel to which the smaller is fixed; the entrance of the liquid taking place
in the latter case near the common shaft of the wheels, and the buckets of the
larger wheel being constructed so as to discharge their liquid gradually, and so as
to be emptied entirely when they arrive at the highest point of their rotatory
motion.
In witness whereof, I, the said Auguste Malfroy, have hereunto set my hand
and scal, this 27th day of July, in the year of our Lord 1876.
