PROVISIONAL SPECIFICATION.
Improvements in Water-meters.
I WILLIAM CLARK, of the firm of A. M. & Wm. Clark, of 53 Chancery
Lane in the County of Middlesex Fellow of the Institute of Patent Agents do
hereby declare the nature of this invention (a communication to me by
Schmidt & Co., of Parco Regina Margherita, No. 2, Naples in the Kingdom of
Italy, through their Agents Wirth and Co., of Frankfort-on-Main, Germany) to
be as follows:-
:-
This invention relates to water-meters and more especially to the materials of
which certain parts of the meter are made and which have been found to be
eminently suited for the purpose.
The meter is composed of a vaned rotating wheel or measuring drum mounted
in a casing as hereafter described and counter-mechanism consisting of a train of
toothed wheels and dials as usual the said wheel or drum together with the shaft on
which it is mounted as well as the pinions and all the arbors of the mechanism
being made of phosphor-bronze or nickel while the toothed wheels are of horn.
The lower bearing of the shaft is also made of horn or agate and the wearing part
of the shaft is made of nickel or agate. The face or dial is made of enamelled
sheet copper or white celluloid and the index-hands of phosphor-bronze; the case
of the meter which is of phosphor-bronze is made in two parts, of which the upper
part constituting the cover of the instrument closed by the glass is provided with a
flange which rests on a corresponding flange of the lower part of the case. A tight
joint is made by the insertion of a paper or leather disc between the flanges. The
water passes in through an inlet at the lower part of the case and after passing
through the measuring drum or wheel out at a central outlet in the bottom of the
case. The vaned wheel or drum is contained in an inner case which is also made of
phosphor-bronze and it is mounted in the outer case and provided with a flange
which forms the top of the water chamber. A space is left between the inner and
outer casings into which the water flows and from which it passes to the drum
through tangential holes in the side of the inner casing. The water flows centrally
out of the vaned wheel case by means of an aperture corresponding to the outlet in
the outer casing. To prevent leakage paper or leather packing rings are inserted
between the bottoms of the casings as well as between the flange on the inner
casing and the part of the outer casing on which it rests. By means of the packing
rings the flow of the water otherwise than past the measuring wheel or drum is
prevented.

Improvements in Water-meters.
I, WILLIAM CLARK, of the firm of A. M. and Wm. Clark, of 53, Chancery
Lane, in the County of Middlesex, Fellow of the Chartered Institute of Patent
Agents, do hereby declare the nature of this invention (a communication to me

page_text: and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to water-meters in which certain parts are constructed of
materials which have been found to be eminently suited for the purpose.
The invention will be described with reference to the accompanying drawings,
forming part of this Specification, in which
Figure 1 shews an external elevation and Figure 2 a plan of the water meter
while Figure 3 is an elevation of the registering mechanism, together with the wing
wheel casing removed from the outer casing and drawn to a larger scale.
The meter is composed of a vaned rotating wheel or measuring drum mounted in
a casing O, and registering mechanism consisting of a train of toothed wheels A
actuating a series of indexes G moving over dials as usual in such meters, the said
wheel or drum together with the spindle C on which it is mounted as well as the
pinions E and all the arbors B of the mechanism being made of phosphor-bronze or
nickel, while the toothed wheels A are of horn. The lower bearing of the spindle C
is also made of horn or agate and the spindle pivot is made of nickel or agate. The
face F bearing the index dials is made of enamelled sheet copper or white celluloid
and the index hands G of phosphor-bronze. The case of the meter which is of
phosphor-bronze is made in two parts of which the upper part H constitutes the
cover of the instrument and is closed by glass. It is provided with a flange J which
is bolted to a corresponding flange K of the lower part L of the case, a tight joint
being made by the insertion between the flanges of a paper or leather packing ring
or washer.
The water enters at an inlet M and, after passing through the measuring drum or
wheel, passes out at a central outlet N in the bottom of the case. The vaned wheel
or drum is contained in an inner case O which is also made of phosphor-bronze and
is mounted in the lower part of the outer case by a flange P which forms the top
of the water chamber, fitting in a corresponding rebated seat in the lower part of
the casing, the part O of the wing wheel casing being so much smaller than the
part L of the casing in which it is received, that an annular space will be left
between the casings into which the water flows and from which it passes to the
drum through tangential holes R in the side of casing O. The water flows out of
the vaned wheel case through a central nozzle Q fitting in the exit orifice N. To
prevent leakage, packing rings of paper or leather are inserted between the bottoms
of the casings O and L as well as between the flange P and its seat in the outer
casing so as to prevent the flow of the water otherwise than through the measuring
wheel or drum and also prevent its escape into the registering mechanism, which
mechanism occupies the upper part H of the casing.
The wheels of the registering mechanism may also be made of phosphor-bronze,
coinage bronze, or delta metal, while the bearings of the spindle C may be of
vulcanite or ebonite and the vaned wheel or drum may be made of celluloid or
vulcanite.
The casing O may be dispensed with the main spindle being journaled directly
in the bottom of the casing, buckets being arranged around the journal bearing
upon the bottom of the casing, the water flowing through a single oblique aperture
into the exit orifice. Any number of similar buckets may be also arranged upon
the underside of the top of the water chamber.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what J.
claim is―
1. A water meter having an external casing made in two parts of phosphor-
bronze, whereof the upper part contains the registering mechanism and the lower
part contains the wing wheel casing likewise made of phosphor-bronze and which
makes a tight joint with the lower part of the ineter casing by its flange, thus
leaving an annular water space between the two casings whence the water enters

in the bottom, as specified."
2. In water meters, constructing the wheels of the registering mechanism as well
as the bearings of the index wheel spindles, of horn.
3. In water meters, constructing the wing wheel, wing wheel spindle, and the
spindles of the registering mechanism, of phosphor-bronze or nickel.
4. In water meters, constructing the bottom pivot bearing of the wing wheel
spindle, of horn or agate.
5. In water meters, constructing the dial or index plate F of enamelled sheet
copper or white celluloid.
6. The water meter constructed as described of the materials specified.
