PROVISIONAL SPECIFICATION.
An Improved Water Meter.
I, LAURENCE HILL, of 2 Alfred Terrace, Hillhead, Glasgow, North Britain,
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved meter for measuring the quantity of water
or other liquids, and consists in the combining of moving parts, which must be
actuated by the person requiring the liquid, with the measuring vessel so that the
liquid to be measured is first admitted into the measure by opening the supply valve
or duct, then the supply valve or duct is closed, and thereafter the discharge valve
or duct is opened and the measure full is run off. The discharge orifice is then
closed and the supply orifice opened, so that the measure may again fill. According
to one plan of carrying out my invention I employ either a two-way tap, or three-
way tap, or I may employ small slide valves for admitting the liquid into the measure
and drawing the measure full off. The plug or axle, moving the valve or other parts
which open and shut, is only allowed to turn in one direction, and a counter is
attached for counting the number of turns of the plug or axle, which will be a
measure of the quantity of water used.
Instead of carrying out my invention with rotary moving parts, I may make them
reciprocating.
I make the measuring vessel of glass so that the person drawing water may see
that the full quantity is supplied; but it may be made of brass or other material.
Dated this 23rd day of October 1890.

COMPLETE SPECIFICATION.
An Improved Water Meter.
I, LAURENCE HILL, of 2 Alfred Terrace, Hillhead, Glasgow, North Britain,
Civil 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 :-
My invention relates to an improved meter for measuring the quantity of water
or other liquids, and consists in the combining of moving parts, which must be
actuated by the person requiring the liquid, with the measuring vessel so that the
liquid to be measured is first admitted into the measure by opening the supply valve
or duct, then the supply valve or duct is closed, and thereafter the discharge valve
or duct is opened and the measure-full is run off. The discharge orifice is then
closed and the supply orifice opened, so that the measure may again fill. According
to one plan of carrying out my invention I employ either a two-way tap, or three-
way tap, or I may employ small slide valves for admitting the liquid into the measure
and drawing the measure-full off. The plug or axle moving the valve or other
parts which open and shut is only allowed to turn in one direction, and a counter is
attached for counting the number of turns of the plug or axle which will be a
measure of the quantity of water used.
Instead of carrying out my invention with rotary moving parts I may make them
reciprocating.

page_text: I make the measuring vessel of glass, so that the person drawing water may see
that the full quantity is supplied; but it may be made of brass or other material.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings, in the several
figures of which corresponding parts are marked with the same letters of 5
reference.
Figure 1 is a vertical section of the meter.
Figure 2 is a modification of the upper part of the measure with air valve.
Figure 3 is a cross section of the plug spindle showing the ratchet and pawl.
Figure 4 is a cross section on the line z z, Figure 1, showing the wheels of the 1
index.
The drawings show a meter having a glass measuring vessel A. The measure A
rests on an india-rubber washer a, and is held down firmly to the base plate B by
the bolt C and nut E. The upper end of the bolt C is screwed into or otherwise
attached to the nut I) of the valve-guard F. Two stop-cocks J J are provided
which are turned by the same handle O, and so arranged that when one is open the
other is closed. One stop-cock is for admitting water, and the other for emptying
the measure. While the measure is being filled air escapes through the holes hhhh,
and a valve G, which may be of india-rubber, closes the air passage 9 when the
meter is full. If the valve be made of metal or other substance of greater specific
gravity than water it must be made hollow or balanced so that when the water
rises up it will float up and close the air passage. The guard F is provided to
prevent the valve G from being tampered with.
The plugs or revolving spindles of the stop-cocks work in collars L L. These
collars may either be cast or bolted on. A ratchet M and pawl n, Figure 3 are
provided so as to prevent the handle being turned the wrong way. O is a disc or
handle for turning the plugs to open or shut the stop-cocks, and u u are tightening
nuts for the two cocks. The two cocks may be worked together by means of
the feather and slot as shown at R, or may be bolted together. Attached to the
spindle of the stop-cocks there is a worm to work the wheels for registering the
number of turns of the handle, or the number of times the measure has been filled
and emptied.
Both
The wheels of the registering index are shown at Figure 4. P is the worm on
the axle of the stop-cocks; b and c are two wheels which work round the same
spindle d, the wheel c working on the hollow spindle of the lower wheel b.
wheels are geared into and turned by the worm P, but one wheel has one tooth
more than the other. If the two wheels have 100 and 101 teeth respectively, then
one wheel will advance on the other by one tooth in each revolution. Thus one
wheel can be used to indicate single turns, while the other will indicate hundreds
By this
of turns. e and fare graduated discs carried by the wheels b and c.
arrangement the two wheels will record 10,000 revolutions. Q is a glass plate
through which the indications of the register can be read off.
Figure 2 shows a mode of fitting the air valve to dispense with the guard on the
top. The glass vessel is held down by a tube C¹ instead of a solid bolt. The tube
having its upper end plugged is screwed into a nut S on the top of the glass, and a
nut E on the lower end holds it tight to the base plate, or if as shown in Figure 2
the measure is made of metal the glass top is secured over a hole in the top T of
the metal measure. The little valve case X is soldered to the tube close to the top
of the tube having the air passages hh which allow the air to enter or escape
through the tube.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The water meter consisting of a measuring vessel which is alternately filled and
ld be tho nonty drawing off

page_text: the water, and a register for indicating the number of times the measuring vessel
is filled and emptied, constructed substantially as described and illustrated on the
accompanying drawings.
