HENRY HILL, BANYARD, of 41, St. Andrew's Hill, Doctors Commons, in the City of
London, Gentleman. "IMPROVEMENTS IN METERS FOR WATER AND OTHER LIQUIDS."
[A communication from abroad by Wilhelm Germutz, of Vienna, Austria.]
My Invention relates to the improved construction of meters for water and other
liquids, and a meter constructed in accordance with my Invention consists preferably
of a casing in the form of a cylinder, upon one side of which is the inlet channel
and a reservoir or trap for mud or sand provided with a sieve.
Upon the side opposite to the mud reservoir is a chamber and the outlet channel.
The water or other liquid after having been measured in the central chamber of
the meter is discharged into the said chamber, the chief advantage of which is to
prevent, or at least greatly diminish the back pressure of the liquid, which
prejudicially affects the correct working of the mechanism of meters.
In the interior of the central or working chamber of the meter two projecting
rings are soldered, by which arrangement a ring channel is formed in close contact
with the inlet chamber and the mud reservoir.
By soldering the last named ring in the casing a complete and safe partition is
obtained between the said ring that forms the channel and the working chamber
of the meter, and the necessity for careful caulking is obviated.
The ring channel is connected with the working chamber of the meter by means
of holes drilled in an oblique or slanting direction through the wall of the ring,
the total area of the cross section of these holes being equal to the area of the cross
section of the outlet.
In the working room of the meter a turbine is fixed upon an axle in a horizontal
position.
The s turbine is made of ebonite, vulcanite, or rubber, and consists chiefly of
a disk, upon the circumference of which square radial vanes are fixed. The centre
line of the disk of the turbine exactly corresponds with the line of the oblique holes
hereinbefore mentioned.

page_text: Under the turbine is a scrow whose head forms bearing for the axle, the sª
screw passes through four wings placed so as to check the flow of the water in the
lower part of the working room; and above the turbine is a partition plate which
also has four wings for the purpose of checking the flow of the water above and
underneath the turbine. Above the partition a plate is screwed on the lid, which
protects against oxidisation the transmission wheels, which are made proferably of
vulcanite, and the main axle and the axle of the stuffing box. The stuffing box
consists of a screw screwed lengthways into the upper wall of the lid. This screw
after being bored has its lower end countersunk and ground to receive a valve
which moves up and down, and is kept in position by a metal spring.
The movement of the counting apparatus which is screwed to the lid, and which
is kept dry by reason of the actuating spindle working through the stuffing box, is
an ordinary arrangement on the decimal system, and I either fix upon the wheel
spindles dials which shew through apertures and record the units, tens, hundreds,
thousands, and so on, or I attach hands to the spindles, and make the dial or dials
stationary, and this plan I find preferable. The counting mechanism is protected
by a glass cover to keep out the dust.
The action of my improved meter is as follows:-The water or other liquid enters
by the inlet channel, and through the mud reservoir and sieve into the ring channel,
and from thence passes through the oblique holes into the working room of the
meter, and the sd holes being bored in a uniform direction, a circular motion is
imparted to the water which actuates the turbine.
The stream of the water then divides in two streams, an upper and lower, which
run smoothly and freely one above and the other below the turbine, by which
means the pressure is removed from the turbine, and the water passes out of the
working room through two openings above and below the ring channel into the
outer chamber, and from thence passes away by the outlet channel.
The revolutions made by the turbine are in exact proportion to the quantity of
water passed through, and the quantities registered by the counting apparatus can
therefore be relied upon as accurate.
