Improvements in Continuous Current Electricity Meters
I, ERNEST SCHATTNER, of 104, Queens Road, Norwich, in the County of Norfolk,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows
1
This invention relates to electricity meters for measuring continuous currents,
of the class depending upon electrolytic action According to the inven-
tion I employ in connection with a voltameter or ordinary continuous current
depositing cell, a spring balance or other suitable arrangement, such voltameter
or the like or part of same being carried by the balance on the like so that a
current passing through the voltameter will affect the weight carried by the
balance. A proportionate part of the current 18 passed through the voltameter
and the balance is calibrated to read direct in Board of Trade units
In one
form of the invention a copper plate of the voltameter 18 suspended to the balance
preferably on a knife edge or edges and a part of the current passes from such
plate to a fixed plate or the cell walls and thence out to a terminal or point
where the main portion of the current which has passed through a suitable
resistance joins it A resistance is also preferably inserted in the voltameter
circuit The balance may be arranged if desired with one two or more dials to
read in units, tens, hundreds of units, and upwards as with other meters
In the case of a gas voltameter the gas bell is carried by the balance, or in other
forms the cell itself may be so carried. Instead of using a spring balance a coun-
terweight for the plate, cell or the like may be emploved such counterweight if
desired being of light material such as iron and dipping into a heavy material
such as mercury
A flexible connection between the counterweight and the plate
passes over a pulley or the like connected with the mechanism of a dial so that
a movement occasioned by the altering weight of the plate or the like is shewn
on the dial.

in and by the following statement:―
This invention relates to electricity meters for measuring continuous currents,
of the class depending upon electrolytic action. According to one form of the inven-
tion I employ in connection with a voltameter or ordinary continuous current
depositing cell, a spring balance or other suitable arrangement, such voltameter
or the like or part of came being carried by the balance or the like so that a
current passing through the voltameter will affect the weight carried by the
balance. A proportionate part of the current is passed through the voltameter
and the balance 18 calibrated to read diect in Board of Trade unite
In the form of the invention illustrated in the accompanying drawing a copper
plate a of a voltameter cell e is suspended to a spring balance b preferably on
knife edges cc The current enters at terminal f and the main portion passes
through resistance g to a terminal hand out, but a portion passes by way of wne 2
to the yoke of the plate a and from thence to the copper cell e which may contain
a copper sulphate solution and out by wire k to the terminal h where it joins the
main portion of the current the current in its passage through the voltameter
depositing from the copper plate a on to the cell e
The spring balance 6 which is provided with a suitable dial or dials will show
the reduction in weight of the plate caused by the deposition of the copper from
same on to the cell so that the plate e continually being weighed and the result
of such weighing exhibited on the dial or dials
It will be seen that the current which passes through the voltameter is always
proportional to the main current going through the lamps or the like, hence the
quantity of copper worn from the plate 18 proportional to the amount of the main
current
It will be obvious that the deposition can take place on to a plate instead of
on to the cell and that this latter could be weighed instead, or the cell itself might
be weighed instead of the positive plate
In the case of a gas voltameter the gas bell or the electrolyte receptacle is car-
ried by the balance Instead of using a spring balance a counterweight for the
plate, cell or the like may be emploved such counterweight if desired being of
light material such as iron and dipping into a heavy material such as mercury.
A flexible connection between the counterweight and the plate passes over a pul-
ley or the like connected with the mechanism of a dial so that a movement occa-
sioned by the altering weight of the plate or the like is shown on the dial
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 18-
1. A continuous current electricity meter in which a portion of a voltameter
cell affected by the current passing is directly connected to the indicating mech-
anism of a spring balance or equivalent device substantially as and for the purpose
described.
2 A continuous current electricity meter in which a plate or part of a volta-
meter or a gas bell or an electrolyte receptacle 18 suspended to the indicating
mechanism of a spring balance or equivalent device, substantially as and for the
purpose described
3 A continuous current electricity meter operating substantially as described.
4 A continuous current electricity meter constructed substantially as described
and illustrated
