PROVISIONAL SPECIFICATION.
A New or Improved Water Meter.
1, EDWARD SCHINZEL, Gentleman, of 5, Riviera di Chiaia, Naples, Italy, do hereby
declare the nature of my invention to be as follows:-
The improved -water meter chiefly comprises :-A cylindrical outer case or box,
closed at one end and provided at the other end with a thick glass cover; an inner
casing of ebonite or hard rubber fitted into the said box and open at the top; a paddle
wheel and a clock-work moved by the same.
The cylindrical box forms two cylindrical compartments, namely an upper cylin ler
of large diameter and a lower cylinder of smaller diameter. The lower compartment
is provided with a water inlet, and with a narrow inner flange for supporting a
packing ring on which re ts the inner casing. The upper compartment is provile.
with a lateral discharge opening for the water.
The inner casing is likewise divided into two cylindrical compartments, the lower
compartment containing the paddle wheel, while the upper compartiment contains the
clock-work or counting mechanism. These two compartments are separate from
each other by a thick ebonite plate, through the centre of which passes the axle of
the paddle wheel supported at its lower end by a step learing.
Between the lower part of the inner casing and the outer box an annulir clearance
space is formed which receives the water from the inlet pipe and communicates with
the lower compartment of the inner casing by oblique passages placed so, that the
water entering through the same meets the paddies or vanes at a sui able angle..
Another set of passages are formed in the roof of the lower compartment and allow
the water to escape to an annular space between the walls of the outer box and the
upper part of the inner casing. These outlet passages are oblique and diagonal at
such an angle, that the water in escaping assists to turn the padille wheel.
The axle of the paddle wheel which is guided by the thick ebonite partition and a
cylindrical boss formed on the same, cominunicates its motion to the wheels of the
counting mechanism. The wheels of the latter are all of ebonite or hard rubber, and
the axles of the same have their bearings in a pair of ebonite dises The said discs
are connected with each other and may be lifted out of the inner casing, together
with the counting mechanism situated between the said discs. The circular glass
cover rests on the upper edge of the inner casing and serves to press the latter down
upon the packing ring placed on the inner flange of the outer casing.

COMPLETE SPECIFICATION.
A New or Improved Water Meter.
I, EDWARD SCHINZEL, Gentleman, of 5 Riviera di Chiaia, Naples, Italy, do hereby
declare the nature of this invention and in what manner the same is to be performed,
O to be particularly described and ascertained in and by the following statement :-
My invention consists of a new or improved water meter in which water is almittel

page_text: from the exterior into a chamber, within a box or easing, and there caused to act
upon a revolving wheel mounted upon a vertical shaft, carrying at its upper extremity
a small gear wheel actuating a train of wheels (similar to those used in clock-work)
for indicating the quantity of water passed through the apparatus.
In the accompanying drawings, Fig. 1 is a vertical section through the meter case,
showing the inner casing in elevation; Fig. 2 is a vertical section through the central
part of the meter; and Figs. 3 and 4 are plans of the water chamber.
The improved water meter comprises, a cylindrical onter case or box of cast iron,
or other suitable material, divided into two compartments, a being the upper and
largest compartment, and 6 the lower one of a smaller diameter. The lower division b
is entirely closed, and an iron cover carrying a thick glass plate t encloses the upper
compartment a. An inner casing of ebonite or hard rubber is fitted within the iron
box, and is also divided into two compartments cand e with a vision plate d, of the
same or similar material, between the two, through the centr
h passes the
axle of a paddle wheel g, working in the lower compartment
rted by a
step bearing at the lower end of the axle.
Between the inner casing e and the outer box b, an annular space v is provided,
which receives the water from the inlet pipe and communicates with the lower
compartment e by oblique passages in the wall of e, so placed that the water entering
through the same meets the paddles or vanes of the wheel g at a suitable angle for
rotating it. Another set of passages m are formed in the roof of the water chamber e
which allow the water to escape to a second annular space u, between e and
thence to the outlet pipe i. The outlet passages m are oblique and diagonal, and at
such an angle that the water in escaping assists to turn the paddle wheel g.
and
The axle of the paddle wheel g, which is guided by the thick ebonised partition d
and a cylindrical boss formed thereon, carries a small gear wheel at its upper end
which serves to communicate motion to a train of wheels f, f, serving as a counting
mechanism, in a manner well known. The counting mechanism is connected with
indicating dials (not shown) for indicating by any desired scale the amount of water
passing through the water chamber e. The wheels f, of the said mechanism, are all
of ebonite or hard rubber with properly formed teeth, and their axles have their
bearings in a pair of ebonite discs, r, s. The parts are so connected with each other
that they may be lifted, with the counting mechanism, out of the inner casing for
cleansing purposes. The circular glass cover t rests on the upper edge of the inner
casing c and when screwed down serves to press the latter down upon a packing
ring placed on the inner flange k of the outer box b. The axles of all the wheels f
are of phospher bronze or other material not liable to corrosion.
The meter operates by admitting water through the pipe which filling the annular
space v enters the chamber e by the oblique slots 7 and thence by the oblique diagonal
orifices m (turning the paddle wheel g by the force of the current), into the opening w
in the annular space u, and finally out through the outlet pipe i.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I wish it to be under-
stood, that my invention consists solely in the use of ebonite as described, and that
I lay no claim to the other features of construction herein before described. What
I claim is :-
{
In a water meter, a train of ebonite wheels mounted upon non-corrodible axles
within an ebonite frame, combined with, and capable of removal from, an upper
chamber of an ebonite inner casing, substantially as and for the purpose herein
described.
