Specification Accepted, 25th Jan., 1887:
I HENRY BRIGHT, Winton House Leamington in the County of Warwick, Justice
of the Peace do hereby declare the nature of my said invention and in what manner
the same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention has for its object improvements in water ineters which are also
adapted for the purpose of measuring other fluids in a simple manner, and without
complicated parts which are liable to get out of order and thus to give trouble.
In order that my invention may be clearly understood and more casily carried into
practice I have appended hereunto a sheet of drawings showing two views of a meter
showing the mode of working which will illustrate the principle without entering into
the more minute working details thereof such as stuffing boxes for spindles &c. which
would be known to any practical meter maker.
Figure 1 is a sectional elevation on line S. T.
Figure 2 is a sectional elevation on line W X.
The following index to the letters marked upon the drawings will be found useful
and they refer to the same parts in both figures:-
A Box drum or outer casing.
B
C
1
Inlet for the water or other fluid.
Outlet for the water or other fluid.
D=The fixed fin or partition bar.
E-The revolving boss or centre enlargement around or upon the arbor or spindle.
F and F Flaps hinged doors or pistons.
G=The arbor or spindle which may run through the centre or boss E or be one
piece with it.
H-The removeable lid or cover of the casing or drum A.
The main body of my meters are composed of the circular metal drum or casing A
which for the purpose of boring and accurately fitting is left open at one end which is
afterwards closed up by the door or removeable cover H fastened by suitable screws
or bolts and which may easily be removed for cleaning or repairs, and to further
facilitate boring the casing, the fin or partition D though fast in its position is put in
separately. There are two openings to the meter one on each side B being for the
inlet of the water or other fluid and C for the outlet thereof these openings being
"

page_text: divided by the fixed fin or other partition D which extends from the drum between
the passages
to the boss or centre E so as to prevent any water entering at the opening B
from passing to the outlet C until it is registered by passing round the boss E as
hereinafter to be described.
The revolving centre or boss E should be considerably smaller than the internal
diameter of the drum or casing A by preference say about half the size but this pro-
portion will vary according to the size of the meter but the centre boss should be always
large enough to keep the flaps, doors or pistons F and F sufficiently short to act quickly
and easily. The boss E should be constructed of metal or vulcanite the latter being
preferred for its lightness the spindle or arbor being of gun metal or other suitable
metal one end of which may g' being pivoted in a bushed or other hole in the solid end
of the casing A and the other end through a suitable stuffing box to prevent any escape
of water and long enough to couple to a suitable counting apparatus and registering
hands too well understood to need explanation here as that forms no part of my
invention. Attached to the centre or boss E by suitable joints or pivots are the two
doors F and F one on each side of the said boss and exactly opposite to each other
and which I construct by preference of vulcanite and so arranged that will extend when
open from the boss E to which they are attached to the inside of the casing or drum A
and thus completely prevent any water from escaping without first forcing them round
thus carrying the arbor with them and so registering the quantity.
door For Fin succession approaches the fixed fin or partition D they are closed
by the rounded edge thereof or a friction roller d¹ may assist this action and prevent
excessive wear upon its edge, and thus each door is closed as it passes the fin D the
power being provided by the other open door or doors for there may be two or more
of such doors according to the size of the meter. To allow the door to pass the fin
accurately suitable recesses are made or formed in the boss E into which they can
receed and when shut the boss will be a perfect circle as the outer of each door is a
segment of such circle but these recesses should be made rather deeper than the
thickness of the doors so that any sand, grit etc which may be contained in the water
may not prevent the door closing sufficiently to pass the edge of the fin.
As each
Slight springs and 3 by preference of copper are attached either to the doors
or boss to reopen them immediately they pass the fin D so that one or more doors
according to the number used will always be open to form the piston for carrying
round the registering spindle or arbor G.
It will of course be evident that the working edge of the fin D may be provided
with a spring packing piece and that the working edges of the doors and F' may
likewise be so fitted so that the wear may be automatically taken up without attention
or loss in measuring.
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 claim is:—
The improvements in water meters having in a drum two or more hinged revolving
arms or doors operated by a fixed feather or fin substantially as and for the purpose
herein set forth.
