PROVISIONAL SPECIFICATION.
Improvements relating to Liquid Resistances.
I, EDWARD WINGFIELD BOWLES, of 28, Victoria Street, in the City of West-
minster, Civil Engineer, do hereby declare the nature of this invention to be as
follows:
The object of this invention is to simplify the construction and working of
liquid resistances, and the invention consists, amongst other things, in reducing
the length of pull on the lever, or wheel required to vary the resistance, in
doing away with the bottom connection through the side of the pot, in dispensing
with the counterweight, and in ensuring a better agitation of the liquid.
In carrying out this invention, both electrodes are made moveable, and they are
made to counterbalance one another.
The rod of the bottom electrode passes down through the top electrode, being
suitably insulated therefrom, and the two rods are connected together by a cord,
which passes round the wheel, or is attached to a lever.
The leads are taken from the top of each rod, so that there is no risk of the
pot leaking, as heretofore.
It will be seen that, by the above arrangement, by turning the wheel in one
direction, the two electrodes will be brought together, and by turning in the
other direction, they will be separated, thus reducing the pull by at least one half.

Improvements relating to Liquid Resistances.
I, EDWARD WINGFIELD BOWLES, of 28, Victoria Street, in the City of West-
minster, Civil Engineer, 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:—
The object of this invention is to simplify the construction and working of
liquid resistances, and the invention consists, amongst other things, in reducing
the length of pull on the lever or wheel required to vary the resistance; in
doing away with the bottom connection through the side of the pot; in dispensing
with the counterweight; and in ensuring a better agitation of the liquid.
In carrying out this invention, both electrodes are made moveable, and they are
made to counterbalance one another.
The rod of the bottom electrode passes down through the top electrode, being

page_text: suitably insulated therefrom, and the two rods are connected together by a cord,
which passes round the wheel, or is attached to a lever.
The leads are taken from the top of each rod, so that there is no risk of the
pot leaking, as heretofore.
In the accompanying drawing I have shown the new resistance in elevation,
partly in section.
A is the jar or vessel containing the electrolyte or liquid. B are the electrodes,
of the usual conical form, which are attached each to a copper rod C. The rod
of the bottom electrode passes freely through the top electrode.
These rods are covered with some acid-resisting substance, and are connected
together by a cord or chain D, which passes round the wheel E, or its equivalent,
which is operated by the handle or lever F, as indicated.
It will thus be seen that the two electrodes will balance one another, and the need
for a counterweight is obviated. It will also be seen that the electrodes move
simultaneously in opposite directions, so that the amount of movement to be given
to them is much less than formerly, consequently the size of the wheel, and the
amount of motion to be given to the wheel E, or to the handle F, is reduced
considerably. The two cones will meet in the middle of the jar or vessel, and
will therefore be clear of the mud which usually collects at the bottom.
It will also be seen that the necessity for passing one of the leads through
the wall of the jar at the bottom is obviated, and thus there is no risk of leaky
joints, as heretofore.
"
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:-
1. A liquid resistance for electrical purposes, constructed, arranged, and
operating as herein shewn & described.
2. In a liquid resistance for electrical purposes, making both electrodes move-
able, as and for the purpose set forth.
