A NEW OR IMPROVED LIQUID METER
Year: 1885

page_text: We JAMES BOWIE, WILLIAM TURNER, and MORTIMER HILL of President Street
Goswell Road in the County of Middlesex Engineers do hereby declare the nature
of our Invention for "A NEW OR IMPROVED LIQUID METER" to be as follows:-
The object of this Invention is the accurate measurement of water as it flows
through a pipe from a Cistern or other receptacle by means of a Meter of novel
construction which may be described as follows:-
We construct a case or cylinder having by preference a circular formation with
an inlet orifice at the top side tangential to its circumference and likewise an outlet
orifice at the bottom placed at about right angles to the inlet orifice. Inside this
case or Cylinder which is provided with suitable covers we mount on the axis
thereof a disc the periphery of which is indented so as to form recesses the surfaces
of which are of a diameter less than the disc. In these recesses so formed we place
floats or blades capable of swivelling on a centre which said floats when closed will
accurately fill in the aforesaid recesses and when extended on their supporting pins
at right angle to the axis of the disc will fit a annular space formed between the
periphery of the revolving disc and the inner periphery of the fixed Cylinder or
case,, this space extends from a point immediately in advance of the inlet orifice
near the top centre of the Cylinder when placed in a vertical position to a point a
little beyond the outlet orifice the remaining distance embraced being filled in with
a cam surface accurately fitting the larger diameter of the inner disc carrying the
blades.
Thus it will be seen that when water or other liquid is allowed to enter the top
orifice it will fill the spaces between the blades sliding in the annular space which
in their revolution will by the action of centre projecting pins as they successively
escape from the can surface assume a radial position and thus form a sliding stop
as the water enters to a point where the water makes its exit. The blades leaving
the escaping water in succession are caused by the aforesaid cam to close in and fill
the recess designed for their reception on the revolving disc in which position they
remain until again passing into the open annular space when each blade is
immediately caused by the aforesaid projecting pin to assume a position which
extends across such space in the manner herein described.
The central axis of the disc is connected with gearing which will enable its
revolution to be accurately indicated on a dial the indications so given being
arranged to accurately denote the quantity of water passing through the meter.

page_text: We JAMES BOWIE, WILLIAM TURNER and MORTIMER HILL, Engineers, of President
Street, Goswell Road, in the County of Middlesex, do hereby declare the nature of
our Invention for "A NEW OR IMPROVED LIQUID METER," and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This Invention relates to improvements in Water Meters in which the measureing
capacity for the liquid is contained in a segmental annular portion of a circular
casing.
The accurate measurement of the water as it flows through such segmental
annular space of the casing is obtained by means of expanding floats or blades
hinged to a disc, which said disc is keyed or otherwise fixed to a central spindle.
The said blades during the time the water flows through the meter are driven
so as to transmit a constant rotary motion to the disc and central spindle, the
revolutions of which are communicated by suitable gearing to an Indicator which
indicates on a dial the accurate measurement or quantity of water passing through
the meter.
The manner in which our improvements are carried out will be understood on
reference to the accompanying Drawings, letters of reference being marked on
corresponding parts on all the Figs. alike.
Fig. 1. represents the Meter in Elevation with the front dial plate removed
shewing the interior construction thereof.
Fig. 2. represents a transverse section of Fig. 3. through the line x-x.
Fig. 3. represents the Meter in elevation shewing the Dials.
In these Figs. a. a is the circular frame or casing of the Machine made in
duplicate halves secured together by. the screws through the flanges a¹. The
circular casing a is provided with an inlet thoroughfare b and an outlet thorough-
fare c, tangential to its circumference placed at right angles to each other. Inside
this case a we mount on the central axis or spindle da dise e the periphery of
which is indented or recessed which recesses are filled in with accurately fitting
blades or floats f connected or jointed by the pins g to the projecting portion of the
disc e.
These blades or floats when closed and fitted into their recesses form with
the projections of the disc e to which they are jointed an even periphery and when
such blades are extended so as to stand out radially from the disc e they will fit
the segmental annular space h formed between the periphery of the revolving disc
and the inner periphery of the fixed casing a. this space extends from a point
immediately in advance of the inlet orifice b at the top to a point a little beyond
the direct flow of the liquid through the outlet orifice c at the bottom; the
remaining distance completing the circle being filled in with a segmental block i
the inner cam segmental surface of which accurately fits the periphery of the
revolving disc when the blades f are closed or lying in their recesses as seen
at Fig. 1.
The face of each blade is provided with a pin k. which when the blades are closed
slides in the groove formed in the aforesaid cam surface block this groove at the

page_text: point m causes each float in succession as they escape from the surface of the cam
block to assume a radial position which they maintain so long as they are
traversing the segmental annular space h.
Thus it will be seen that when water or other liquid is turned on and allowed
to enter the top orifice b it will fill the spaces between the blades f sliding in the
segmental annular space h. These blades when escaping from the segmental cam
block are first by reason of their projecting pins and secondly by the water
thrown into a position extending over the segmental annular space h down which
they are forced by the flow of water to a point where the water makes its exit
from the outlet orifice C.
The blades giving motion to the disc e are each in succession as they ascend
from the escaping water caused by the segmental cam block i to close in and fill
the aforesaid recesses formed in the periphery of the revolving disc in which closed
position they remain until again escaping from the cam surface into the open
segmental annular space h, when they are again caused in manner as aforesaid to
assume a radial position. The central axis or spindle d of the disc is connected
with gearing which will enable its revolutions to be accurately indicated on-the
dial o the indications so given being arranged accurately to denote the quantity of
water or other liquid passing through the Meter.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed We declare that what
we claim is
The novel arrangement combination and employment within a fixed circular
casing of a revolving disc driven by a flow of water or other liquid through the
medium of expanding and contracting floats, the revolution of which disc will
accurately indicate the measurement of water or other liquid in the manner as
herein substantially described set forth and fully illustrated in the drawings
annexed.
