IMPROVEMENTS IN METERS FOR WATER OR OTHER LIQUIDS
Year: 1884

page_text: I WILLIAM GEORGE STUART of 2 St Neot's Terrace Vicarage Road Croydon
in the County of Surrey Engineer do hereby declare the nature of said Inven-
tion for "IMPROVEMENTS IN METERS FOR WATER OR OTHER LIQUIDS" to be as
follows:-
My Invention relates to improvements in Meters for water or other liquids and
has for its object simplicity of construction certainty of action and precision or
accuracy in measurement.
It consists of a cylindrical chamber or vessel closed at each end and having
longitudinally through its centro a circular spindle from which projects a plate or
fan occupying the entire half longitudinal sectional area of the chamber or vessel
and capable of partly revolving therein 'with its outer radial edge bearing water--
tight against the inner circumferential surface of the chamber or vessel and its
end edges against the respective ends thereof.
Occupying the entire half longitudinal sectional area of the chamber or vessel
except where the centre spindle occurs is a web or partition having its two sides
radial to the circumference of the chamber or vessel and its inner edge in water-
tight contact with the contre spindle-In the thickness of this web or partition is
fitted a plug, valve or slide which is in combination with the main inlet and outlet
pipes and with one (or more) passages opening through each side of the web or
partition into the chamber or vessel,-By the action of this plug, valve or slide the
water coming through the main inlet pipe can be diverted so as to enter the
chamber or vessel through each side alternately of the web or partition between
the latter and the plate or fan the water contained in the chamber or vessel between
the plate or fan and the web or partition on the opposite side of the latter at the
same time being directed through the outlet or service pipe to use.
The plug valve or slide may be worked in various ways-According to one
arrangement I fix on one end of the centre spindle outside the chamber or vessel
the segment of a bevil wheel gearing into a bovil wheel on a second spindle which
is mounted at right angles to the centre spindle in suitable bearings-Near one
end of this second spindle is a lever from the extremity of which hangs a weight
(or weights) enclosed in a suitable casing formed on or attached to the chamber
or vessel. On the second spindle are also fixed two arms or wipers (one on each
side of the spindle) which are alternately caused to strike and, throw over an arm
or lever or other device actuating the plug valvo or slido.
°

page_text: My improved meter operates in the following manner :-The plate or fan on the
centre spindle being against one side of the web or partition and the plug, valve,
or slide in such a position that communication is established between the inlet pipe
and the opening (or openings) on that side of the web or partition the water enters
the chamber or vessel and pressing against the plate or fan causes it (with the
centre spindle) to travel round the chamber or vessel and in so doing the bevil
segment rotates the bevil wheel on the second spindle which raises the lever and
weight until the plate or fan reaches (or nearly so) the other side of the web or
partition when the bevil wheel arriving at the blank portion of the bevil segment
the bevil wheel thereby slips or is released and allows the lever and weight to
descend to their original position this causes one of the arms or wipers on the
second spindle to throw over or reverse the position of the plug, valve, or slide so
as to divert or cause the water from the main inlet to enter the chamber or vessel
through the other side of the web or partition and return the plate or fan to its
original position--at the same time the water contained in the chamber or vessel,
between the first named side of the web or partition and the plate or fan is allowed
to pass through the outlet or service pipe for use.
It is evident that the space between either side of the web or partition and the
plate or fan being of any known capacity the quantity of water passing through
the meter can be automatically and accurately measured and registered by any
suitable counting apparatus which may be actuated by the second spindle or any
other moving part of the mechanism.
According to another arrangement I may dispense with the bevil segment and
wheel, the lever for carrying the weight, and the arms or wipers on the second
spindle for reversing the plug valve or slide; and in lieu thereof I may have a cam
shaped piece attached to the end of the centre spindle the second spindle in this
case being converted into a lever which is hinged at one end to the side of the
casing and passed through the shank or stem of the plug valve or slide the weight
being suspended from its other end.-By the action of the cam shaped piece on tho
movement of the centre spindle the said lever is caused to rise to the highest point
of the cam on passing which the weight causes the lever to descend and reverse
the position of the plug valve or slide-Or in lieu of a weight for depressing the
second spindle or lever I may use a spring.

I WILLIAM GEORGE STUART of 2 St. Neot's Terrace Vicarage Road Croydon in
the County of Surrey Engineer do hereby declare the nature of said Invention
for "IMPROVEMENTS IN METERS FOR WATER OR OTHER LIQUIDS 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 improvements in Meters for water or other liquids and
has for its object simplicity of construction, certainty of action and accuracy of
measurement.
On the accompanying sheet of drawings Figure 1. represents a vertical sectional
elevation of my improved a meter with my improvements applied thereto―
Figure 2. a sectional plan of the meter on line 1, 2 in figure 1.-Figure 3. a
sectional plan on line 3, 4 in figure 1 shewing the reversing gear and Figure 4. an
end sectional view of the latter on line 5, 6 in figure 1.-like letters of reference
indicating like parts in the respective figures.
My invention The meter consists of a cylindrical chamber or vessel a closed at
its ends by circular plates b and c which are recessed into the annular ends of the
cylindrical chamber or vessel a the top plate 6 being secured thereto by the flange
of the casing d which contains the reversing gear and registering devices of the
meter and the bottom plate c by a cover e-Through the centre of the chamber or
vessel a and plates bo passes a circular spindle f which is confined endwise between
the plates bc by shoulders and terminates at its lower end outside the plate c in
a centre or bearing g of glass or other suitable material let into the cover e whilst
its upper end projects beyond the plate b into the casing d.
From the spindle ƒ (on one side only) projects a plate or fan h which is capable
of partly rotating to and fro with the spindle f in the chamber or vessel a its outer
vertical edge bearing watertight against the inner circumferential surface of the
chamber or vessel a whilst its top and bottom horizontal or radial edges bear
against the inside surfaces of the end plates b and c respectively-Or if desired
more than one fan or blade may project from the centre spindle f
Occupying the half longitudinal sectional area at the middle of the chamber or
vessel a except where the central spindle ƒ occurs is a wedge shaped web or
partition which is fixed watertight at its outer or thick edge to the inner surface
of the chamber or vessel a its sides radiating (or otherwise) therefrom to the centre
spindle fagainst which its inner or thin edge is in watertight contact-In the body
or thickness of this web or partition i is a cylindrical well or pocket j into which
is fitted a specially formed parallel four-way cock or valve k from which projects
upwards beyond the top end 6 of the chamber or vessel a. a stem 7 carrying a
horizontal arm or lever m by which the cock or valve k is partially rotated in
either direction as hereafter more particularly described-This cock or valve k is
in combination with the main inlet pipe n, outlet passage o (and pipe o²) and with
passages ppl opening respectively from the cylindrical pocket ; through each sido
of the web or partition & into the chamber or vessel a.
By the action of the four way cock or valve k water or other liquid coming
through the main inlet pipe n can be diverted so as to enter the chamber or vessel a
"

page_text: alternately through each side of the web or partition i and from the chamber or
vessel a through the outlet passage o (and service pipe o¹) to use.
The four-way cock or valve k may be operated in various ways-According to
one arrangement I fix on the upper projecting end of the centre spindle f outside
the chamber or vessel a the segment g of a bevil wheel which gears into a bevil
wheel r fixed on a second spindle s the latter being mounted horizontally at right
angles to the centre spindle on centres or bearings & carried by standards u which
are secured to the upper side of the top plate b-On this second spindle & are lovers
and weights v. w. by the throwing over and falling of which in each direction the
arm or lever m of the four-way cock or valve k is struck by one of the weights w
so as to cause the cock or valve k to bo thrown over or partially rotated alternately
to and fro.
T
My improved The meter operates in the following manner:-The plate or fan h
on the centre spindle ƒ being at the limit of its traverse near one side of the web or
partition i as shown by dotted lines at h¹ in figure 2 and the four-way cock or
valve k in such a position that communication is established between the inlet
pipe and the passage p on that side of the web or partition i the water enters
the chamber or vessel a through passage p and pressing against the plate or fan h
causes it (with the centre spindle f) to travel partly round the chamber or vessel a
and in so doing the bevil segment q rotates the bevil wheel r and second spindle s
which gradually raises and throws over the levers and weights v. w. in the direction
shown by the arrow in figure 4 until the plate or fan h reaches the limit of its
travel towards the other side of the web or partition i (or into the position shown
by dotted lines h in figure 2) when the bevil wheel r arriving at the blank in the
bevil segment g the bevil wheel r slips or is released and allows the weight w to
descend suddenly and in so doing one of the weights w. strikes the arm or lever m
and partially rotates or throws over the four-way cock or valve k into the position
shown by dotted lines in figures 2 and 4 thereby diverting or causing the water
from the main inlet pipe n to enter the chamber or vessel a through the passage pl
on the other side of the web or partition and return the plate or fan h to its
original position when the cock or valve k will be reversed by the falling of the
weights w in the other direction-In the meanwhile the water contained in the
chamber or vessel a between the first named side of the web or partition i and
the plate or fan h passes through the passage 2, outlet passage o and service pipe o¹
to use. The above operation is repeated as long as the service pipe o' remains open
but when this is closed and the water consequently ceases to flow through the meter
the plate or fan h becomes stationary until the service pipe is again opened.
It is evident that the maximum space traversed on either side of the wob or
partition by the plate or fan h being of any known or determined capacity the
quantity of water passing through the motor can be automatically and accuratoly
measured and registered by a suitable counting apparatus which may be actuated
by a fork or double lever x (figure 1) the two arms of which are alternately pushed
aside by a lump or projection y on one of the weights was the latter is thrown
over in each direction thereby giving a to and fro motion to the spindle % of the
fork or double lever which motion may be utilised to work a counting apparatus
contained in the index box at the top of the casing & or in any other suitable
position Or the counting apparatus may be actuated by any other moving part of
the measuring apparatus as may be found most convenient Figure 5 shews a
modified construction of the plato or fan h seen in figures 1 and 2 whereby its
rubbing edge may be adjusted to the periphery of the cylindrical chamber or
vessel u in order that any undue wear of its such rubbing edge may be taken up
so as to ensure a more perfect watertight contact with the said chamber or
vessel a.
According to another arrangement for reversing the four way cock or valve k
I dispense with the bevil segment q wheel r standards u levers and weights wi
and in lieu thereof I fix a double inclined or concave cam shaped piece to the upper
projecting end of the centre spindle substituting for the second spindle & a levor

page_text: which is hinged at one end to the stem 7 of the four way cock or valve k at such
an angle horizontally that when the latter is at its limit of rotation in either
direction it the said lever will rest on the lowest portion of the corresponding
inclined or concave side of the cam shaped piece a weight being attached to the
other end of the lever-On the partial rotation of the centre spindle ƒ in either
direction the lever is constrained to rise to the highest point of the cam shaped
piece on passing which point the weight causes the lever to descend the other
side of the cam shaped piece and in so doing reverses the four way cock or
valve k. -
I am aware that liquid meters have before been constructed with plates or
fane partially rotating or oscillating to and fro in cylindrical chambers or
vessels provided with fixed webs or partitions containing distributing valves and
inlet and outlet passages, such valves being operated by tumbling weights raised
by the action of the said oscillating plates or fans, and released by various means;
and I wish it to be understood that I make no claim to the construction of such
meters generally.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In a meter for water or other liquid the combination--and arrangement
of in which a plate or fan (or fans) projecting from a centre spindle in a
cylindrical chamber or vessel; with a fixed web or partition having inlet and
outlet passages through which-water or other liquid flowing-from-the-main-inlet
pipe--is--enused to--enter and leave the--chamber--or--vessel-at-opposite sides
respectively of the web or partition alternately and in so doing partially rotates
or rotate the plate or fan. (or fans) with the centre-spindle to and fro in the a
cylindrical chamber or vessel containing a fixed web or partition substantially-as
and for-the-purpose hereinbefore-described and illustrated by-the-accompanying
drawing. 9. the combination and use of a the parallel four way cock or valve when
constructed as hereinbefore described and illustrated in Figures 1 and 2 of the
Drawings with the fixed web or partition and with the inlet and outlet passages to
and from the chamber or vessel substantially as and for the purpose herein before
described and illustrated by the accompanying drawings.
3. 2. The method of and combined mechanism for throwing over or reversing
the position of the four way cock or valve substantially arranged, combined,
and operating as herein before described and illustrated by the accompanying
drawings.
4.3. The general construction combination and arrangement of meter for water
or other liquid substantially as hereinbefore described and illustrated by the accom-
panying drawings, the plate or fan ǹ being constructed as illustrated in Figure 5
of the said Drawings

figure 1.-like letters of reference indicating like parts in the respective figures.
My invention consists of a cylindrical chamber or vessel a closed at its ends by

leave the chamber or vessel at opposite sides respectively of the web or partition
alternately and in so doing partially rotates the plate or fan (or fans) with the
centre spindle to and fro in the chamber or vessel substantially as and for the
purpose herein before described and illustrated by the accompanying drawing.
