IMPROVEMENTS IN APPARATUS FOR MEASURING WATER OR OTHER LIQUIDS
Year: 1884

page_text: I, WILLIAM ROBERT LAKE of the firm of Haseltine, Lake and Co Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my Invention for "IMPROVEMENTS IN APPARATUS FOR MEASURING 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 :-
This Invention relates to apparatus for measuring water or other liquids and
comprises improvements in the construction of the casings of water-meters and in
the adaptation of the said casings to receive two different kinds of mechanism.
It further comprises the improvements hereinafter described.
In the accompanying Drawing
Figure 1 is a vertical longitudinal section, and
Figure 2 a plan of a water-meter casing constructed according to the said
Invention.
Figure 3 is a vertical transverse section of a water-meter made with my
improved casing and in which the water has access to the whole of the registering
mechanism.
Figure 4 is a vertical transverse section of a water-meter made with my improved
casing and in which the water cannot enter the upper chamber enclosing the
registering mechanisın.
Figures 1 and 2 illustrate the arrangement of the admission pipe d and the
discharge pipe e. The registering mechanism can be placed on the right or left
hand side within the casing so that it is a matter of indifference from which side
the water is admitted; the registering mechanism can be inserted in such a manner
that the indexes or pointers are always in front. The mechanism of the water-
meter may moreover be removed and replaced by new mechanism, without
necessitating any alterations in the construction of the casing.
Figures 3 and 4 show the improved construction of the vanes for the rotating
wheel a, the flaps or parts forming the vanes being bent at right angles upwards
and downwards.
The admission of the water through the pipe g can be regulated, in order to
compensate for any inaccuracies in the measurement,

page_text: With the registering mechanism working in the water (Figure 3) the small
casing b containing the registering mechanism rests by means of four adjustable
pins n n on the shoulder o (Figure 1) of the casing f; any injurious pressure upon
the registering mechanism when the ring c is screwed down is thus obviated.
The rim p of the small casing 6 fits exactly into the casing f. The thick glass
plate h rests upon the packing ring q and the casing is made water-tight by
screwing down the ring c.
If the casing is to be used to contain the registering mechanism working in
water, the rim (Figure 1) is simply turned off and the aforesaid ring 9 (Figure 3)
which is of india-rubber or other suitable material ensures perfect tightness of
the casing.
The registering mechanism in the small casing b (Figure 3) is provided with a
closing arrangement which prevents the entrance of the water from the lower
chamber into the upper chamber. To the plate separating the chamber containing
the registering mechanism from the compartment holding the measuring mechanism,
is attached a tube which is open at the bottom, and a smaller tube, which is open
at the top and extends into the larger one, is secured to the main spindle; the
circulation of the water in the casing for the registering mechanism is thus
obviated.
If the registering mechanism is to work in a dry state, it is divided into two
parts, of which only one rotates in the water, whilst the water is excluded from
the dial-plates. The closing is effected by a partition plate 8 (Figure 4) and the
small casing for the registering mechanism rests upon the packing-ring t; the
aforesaid adjusting pins n are, therefore, dispensed with. The small casing is
screwed on by means of the ring 1, and the latter supports a cylindrical casing k
which is closed at the top by a thin glass-plate i, or, in some cases, by a cover m.
Figure 4 shows, moreover, the arrangement of the registering mechanism. The
main spindle is provided with a suitable stuffing-box or device for preventing the
access of water to the registering mechanism.
Instead of the wheel arrangement represented in Figure 4, worms and worm-
wheels might be employed.
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:
First. The general arrangement and construction of a water-meter, in which
the registering mechanism works in water or not, as above described and shown
in the accompanying Drawing.
Second. In a water-meter in which the registering mechanism works in water,
the application of the adjusting-pins n and of the packing-ring q, substantially as
described.
Third. The improved construction of the vane-wheel a as represented in
Figures 3 and 4.
Fourth. The improved construction of the casing f which permits of employing
mechanism working in water or not and of inserting the said mechanisin in the
casing so that the water can be admitted from either end, and of employing spare
mechanism, substantially as described.
