marthen S.W. do hereby declare the nature of this invention' to be as follows:
1
Consisting of a drum, having six or more compartments, perfectly tight with
the exception of holes slotted on the breast, equal in number to the compartments,
and length half the distance between each compartment, width as required. Drum
to be cased in accordance to size and provided with bearings each side for spindlo
of drum to work in; one of the bearings having a packing gland allowing spindle
to pass through the side, to which is connected worm for working index. On the
upper part of drum a saddle valve is arranged, length equal to distance of one &
half compartments, width as required; the valve fitted to sweep of drum, gas or
water admitted about centre of valve, but the hole to be of same shape, as slotts
on drum, tho' a little longer, as the gas or water is admitted the drum will
revolve. So soon as one compartment is charged; the valve admits gas or water to
the next, at the same moment freeing the one previously charged to outlet of
meter. The valve is encircled by a leather or India rubber flange which is fastened
to the sides of meter case thus preventing gas or water passing to the outlet
without registration.

page_text: İ, ALFRED GEORGE BROWNING, Gas Engineer, of 4, Grenfield Villas, Llanelly,
South Wales, 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 construction of meter for water, gas, or
similar fluids and consists of a drum single or compound, and divided into sector
shaped chambers. Openings are formed in the periphery of the drum to admit
the fluid to be measured into the chambers. The drum is mounted within a
suitable case fitted with inlet and outlet connections. The former is expanded into
a saddle valve the face of which is shaped of the same radius as the drum, the
periphery of which it fits sufficiently closely to prevent the escape of the fluid
passing through the meter.
The length of the valve is about equal to a quadrant of the periphery of the
drum and conveniently embraces three of the openings therein. The chambers fill
as they come opposite the valve, and empty as the weight or pressure of fluid
causes the drum to rotate on its axis. A suitable index is fitted upon one end of
the axis which is continued through a stuffing box in the side of the case.
In order that my invention and the means by which the same is to be carried
into effect, may be thoroughly understood, I will proceed to describe the same in
detail, referring in so doing to the accompanying drawings which are to be taken
as part of this specification and read therewith, and in which like parts are
marked throughout with the same reference letter.
Fig. 1 is a sectional end elevation of the drum.
Fig. 2 is an end elevation, partly in section, of the drum and its case.
Fig. 3 is a sectional side elevation of the drum and case.
A is the drum and a the openings or ports in its periphery. B is a diaphragm
making the drum a duplex one. I do not confine myself to any particular number
of diaphragms, as this can be regulated according to the width of the drum.
C is the axis passing through a bush c formed in the centre of the drum, to
which it is rigidly fixed in any convenient way."
The ports are shewn in Fig. 2 as aligned across the breast of the drum but they
may be advantageously interspaced when more than one diaphragm is used.
The compartments produced by the sides D of the drum and the diaphragms
may be of equal or different widths. Radial webs E extending from the bush c to
the periphery of the drum divide each compartment into sector shaped chambers F.
G is the meter case, one side of which has a closed bearing formed in it to receive
the axis, while the other side is fitted with any suitable kind of stuffing box
through which the axis passes into a box g containing an index the first wheel g¹
of which only is shewn.
H is the inlet connection which is passed through the case, inside which it is
expanded into a saddle valve I. The face of this valve is an arc of the same radius
as that of the drum, and is packed with rubber or similar material to make a
perfectly tight joint with the periphery of the drum which is turned up true for

page_text: the purpose. The valve is of the same width as the drum with a clear internal
width capable of embracing a line of ports as shewn in Fig. 2, the margins of
periphery surface outside the ports furnishing sufficient bearing surface for the
returned cheeks i of the valve. The cross faces i¹, i, of the valve are considerably
wider than a port for the purpose of preventing the leakage past them of
unmeasured fluid.
The valve is shewn in Fig. 3 as long enough to embrace three ports. I do not
confine myself to this proportion as it may be made relatively smaller than this,
provided that it be large enough to have at least one port embraced by it as the
drum revolves.
I shew this valve and the inlet connection as fixed to one of the top corners of
the case, which is a convenient position although, any other may be adopted pro-
vided that the fluid to be measured enters the drum above the horizontal plane
passing through its axis.
The operation of the meter as as follows.
The fluid to be measured enters the valve by the inlet H and fills as many of the
chambers F as are in communication with the valve. The weight or pressure of
the fluid causes the drum to revolve, its contents being discharged into the case as
the ports pass beyond the valve face and escaping by the discharge J, the sectional
area of which is equal to that of the inlet H.
The ports of the measuring drum may be cut on the peripheries of smaller.
drums one on each side thereof, each having its inlet and saddle valve and
discharging into the central drum which may be divided by a diaphragm.
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,
The combination of saddle valve the concave face of which is of the same arc
as that of a drum divided into radial chambers with said drum, and an outer case
having an inlet and a discharge the periphery of the drum making a fluid-tight
joint with the concave face of the valve as it is pulled past it, by the weight or
pressure of the fluid admitted into its chambers, substantially as described with
reference to the accompanying figures.
