"IMPROVEMENTS IN
LIQUID METERS." A communication from abroad by Edward Reade-Westhead, of
Paris, in the Republic of France.
The Invention has for its object improvements in liquid meters.
The lower part of the meter is formed with a case provided with an inlet at the
lower part on one side, and an outlet at the upper part on the other side thereof.
Above this lower case is fixed a case enclosing the counting gear and dial, which
case has no passage of communication whatever with the lower one, whereby the
dial and counting gear are completely insulated from the liquid to be measured
without the necessity of using packing for that purpose.
The measuring apparatus consists of a wheel or fan formed of thin non-corrosive
metal, the blades of which are set at an angle to a vertical plane. This wheel is
mounted in suitable bearings, and is enclosed in a case or measuring chamber fixed
to the upper case, and mounted centrally in the lower case.
This measuring
chamber has fixed on the exterior thereof a horizontal ring or flange, which, in
combination with a ring or flange and suitable packing in the interior of the lower
case, serves to divide the lower case or chamber into two parts horizontally, the
lower part forming an inlet chamber to receive the water from the supply, and
the upper part forming an outlet chamber to receive the liquid from the, measuring
chamber, and deliver it to the outlet orifice.
Below the flange, on the outside of the measuring chamber, are a number of holeś
formed obliquely through the case of the said chamber, so as to cause the inlet
water to impinge in angular directions against the blades of the wheel or fan, and
thereby give rotary motion thereto. In this lower part of the case of the ineasuring

page_text: chamber is also formed a regulating hole at right angles thereto, through which hole
a current of water passes in a line direct towards the axis of the fan or wheel.
The stream passing through this regulating hole may be regulated in force by
means of a screw, the end of which is opposite the said hole. Thus by regulating
the force of water passing through said hole, the action of the meter may be
regulated without the risk of injury to the fan or wheel.
The case of the measuring chamber above the exterior flange is provided with a
number of comparatively large holes to permit the liquid to pass out therefrom into
the upper part of the lower case, whence it passes away by the outlet.
The axis of the fan or wheel has formed or fixed thereon a pinion, which gives
motion to a toothed wheel, on the axis of which is another pinion, which gives
motion to a toothed wheel, on the axis of which is fixed a magnet. This train of
gearing is enclosed by a thin casing, which, although not water-tight, prevents the
current of water entering, and leaving the meter from interfering with the motion
of the said gearing.
The magnet acts upon a piece of soft iron fixed on the axis of the first counting
wheel, and so communicates motion to the counting apparatus without being other-
wise connected thereto.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Paine in the Great Seal Patent Office on the 10th January
1878.

"IMPROVEMENTS IN
LIQUID METERS." A communication from abroad by Edward Reade-Westhead, of
Paris, in the Republic of France.
The Invention has for its object improvements in liquid meters.
The lower part of the meter is formed with a case provided with an inlet at the
lower part on one side, and an outlet at the upper part on the other side thereof.
Above this lower case is fixed a case enclosing the counting gear and dial, which
case has no passage of communication whatever with the lower one, whereby the
dial and counting gear are completely insulated from the liquid to be measured
without the necessity of using packing for that purpose.
The measuring apparatus consists of a wheel or fan formed of thin non-corrosive
metal, the blades of which are set at an angle to a vertical plane. 'This wheel is
mounted in suitable bearings, and is enclosed in a case or measuring chamber fixed
to the upper case, and mounted centrally in the lower case. This measuring
chamber has fixed on the exterior thereof a horizontal ring or flange, which in
combination with a ring or flange and suitable packing in the interior of the lower
case serves to divide the lower case or chamber into two parts horizontally, the
lower part forming an inlet chamber to receive the water from the supply, and the
upper part forming an outlet chamber to receive the liquid from the measuring
chamber and deliver it to the outlet orifice.
Below the flange, on the outside of the measuring chamber, are a number of holes,
formed obliquely through the case of the said chamber, so as to cause the inlet
water to impinge in angular directions against the blades of the wheel or fan, and
thereby give rotary motion thereto. In this lower part of the case of the measuring

page_text: therefrom into the upper part of the lower case a, whence it passes away by the
outlet a².
The axis c' of the fan or wheel c has formed or fixed thereon a pinion c², which
gives motion to a toothed wheel f', on the axis ƒ of which is another pinion f2
which gives motion to a toothed wheel g', on the axis g of which is fixed a magnet g².
This train of gearing is enclosed by a thin casing , which, although not water-
tight, prevents the current of water entering, and leaving the meter from interfering
with the motion of the said gearing.
The magnet g acts upon a piece of soft iron fixed on the axis i of the first
counting wheel, and so communicates motion to the counting apparatus without
being otherwise connected thereto. This mode of communicating motion from the
measuring apparatus to the counting apparatus is also applicable to other con-
structions of liquid meters.
The counting gear may be of any ordinary construction, and as such is well known
I have not given a description thereof.
Having thus described the nature of the said Invention and the mode in which
the same is carried into effect, I would have it understood that what I claim is,―.
Firstly. The peculiar arrangement and combination of parts of a liquid meter,
substantially as herein shown and described.
Secondly. I claim the mode of regulating the action of liquid meters by means of
a small stream of liquid passing in a line directly towards the axis of the fan or
wheel, and capable of regulation, substantially as herein shown and described.
And, Thirdly. I claim the mode of communicating motion from the measuring
apparatus to the counting gear in liquid meters, whereby the counting gear is
completely insulated from the water passing through the measuring chamber,
substantially as herein shown and described.
In witness whereof, I, the said William Paine, have hereunto set my hand
and seal, this Tenth day of January, in the year of our Lord One thousand
eight hundred and seventy-eight.
