I, JULIUS WILLIAM STAWITZ of Frankfort-on-Main, in the Empire of Germany,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention consists in certain improvements in water meters.
A chamber having substantially the shape of one revolution of a scroll is placed
horizontally and is fed by the water; the latter, being directed horizontally along
against the wall of the scroll, flows along the wall and passing around with the latter,
is, at the end of one revolution, pursuing a course parallel to the entering water, but
at a distance nearer to the centre of chamber. A whirl is thereby produced in the
water which carries with it a wheel provided along its periphery with radial plates or
wings, and vertically journalled in the chamber. The wheel is of such a size that
the said arms nearly touch the side of the chamber at the point where the latter is
nearest to the centre, namely where the incoming water has completed a revolution.
The water passing revolves this wheel and is also deflected into the centre of the
chamber where it falls into a receiving pipe, which conveys it to its destination.
Above the chamber and geared by a suitable train to the shaft of the wheel is the
dial (or dials) indicating the number of revolutions and therefore the amount of water
that has passed. The inlet pipe may be connected direct to the outlet pipe by means
of a pipe provided with a cock, so that more or less water may he allowed to pass
without operating on the wheel; this device therefore serves as a regulator for adjust-
ing the dial to agree with the actual quantity of water delivered. Stationary deflecting
plates may be arranged in the centre of the chamber to turn the water into the outlet,
and thus cause the water to pass the meter more quickly.
The gearing for transmitting the high speed rotary motion of the winged wheel
to the dials, consists of a train of pinions and cog wheels rotating freely upon fixed
shafts. Each cogwheel has its pinion fixed to it and a hole passes through the centre
of both. The two shafts or pins are fixed parallel to each other at a proper distance
apart, and the wheels are placed upon these shafts alternately right and left to complete
the train.

Engineer do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention consists in certain improvements in water meters.
A chamber having substantially the shape of one revolution of a scroll is placed
horizontally and fed by the water: the latter, being directed horizontally along
against the wall of the scroll, flows along the wall and passing around with the latter
is at the end of one revolution, pursuing a course parallel to the entering water, but
at a distance nearer to the centre of chamber. A whirl is thereby produced in the
water which carries with it a wheel provided along its periphery with plates or wings
and vertically journalled in the chamber. The wheel is of such a size that the said
arms nearly touch the side of the chamber at the point where the latter is nearest to
the centre, namely where the incoming water has completed a revolution.
The water passing revolves this wheel and is also deflected into the centre of the
chamber where it falls into a receiving pipe which conveys it to its destination.
Above the chamber and geared by a suitable train to the shaft of the wheel is the
dial (or dials) indicating the number of revolutions and therefore the amount of water
that has passed. The inlet pipe may be connected direct to the.oulet pipe by means
of a pipe provided with a cock, so that more or less water may be allowed to pass
without operating on the wheel, this device therefore serves as a regulator for adjust-
the dial to agree with the actual quantity of water delivered. Stationary deflecting
plates may be arranged in the centre of the chamber to turn the water into the outlet
and thus cause the water to pass the meter more quickly.
The gearing for transmitting the high speed rotary motion of the winged wheel
to the dials consists of a train of pinions and cogwheels rotating freely upon fixed
shafts. Each cogwheel has its pinion fixed to it and a hole goes through the centre of
both. The shafts or pins are fixed at proper distances apart and the wheels are put
upon these pins to complete the train, rotating eventually upon the points of these
pins.
In order that my invention may be readily understood I have appended a sheet of
drawings of my improved water meter of which Fig. 1 is a vertical section and fig. 2
a horizontal section a casing, binlet, e sieve, d measuring chamber, e outlet, f gear
framo, dial, cover, i regulating screw or valve, in a channel ix connecting the
inlet and outlet ways, wheel with vertical radial wings or plates k,l spindle connecting
the wheel to the gear m, n index actuated by the gear m.
The said gear may be of usual construction but it is preferred that the gear wheels
and pinions should be connected by sleeves which fit freely on pointed studs o as
shown in fig. 3 so that the said gear may be readily removed from the casing
when necessary for repairs or otherwise.

page_text: The action of the apparatus is as follows.
The screw or valve i is adjusted and the area of the channel ix regulated until the
water to be measured will when unobstructed flow through the meter and act on the
wheel at the required velocity.
The water enters the measuring chamber and flows in contact with the outer wall
by which it is gradually caused to depart from a straight course until it has motion
in a circular path so as to actuate the wheelj by pressure against the wings or plates k.
The water finally passes away by the outlet e. It is evident from the shape of the
chamber, and position of the wheel and inlet and outlet ways that the water will make
a complete revolution in the chamber before it fully engages with the wings of the
wheel.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I
claim is.
First. Water meters consisting of a case having a measuring chamber provided
with inlet and outlet ways in combination with indicating appliances all substantially
as set forth.
Second. Constructing index gear for water meters with gear wheels and pinions
carried on pointed studs substantially as set forth.
