Improvements in or relating to Means for Preventing the Creeping of
Acids or other Deleterious Matter in Electrical Apparatus.
We, JOB THOMAS NIBLETT and MALCOLM SUTHERLAND, Electrical Engineers, both
of 61, Chandos Street, Strand, London, do hereby declare the nature of this
invention to be as follows:-
1
The invention which relates to means for preventing the creeping of acids or
other deleterious matter in electrical apparatus, consists of a trap through which
the part to be protected passes, and containing a suitable liquid, preferably oil,
for arresting the progress of the deleterious matter.
In one form which we have found to give satisfactory results in connection
particularly with secondary batteries we use a tube of non-conducting material
bent into U-shape, through which the conductor whereon the creeping is to be
prevented, passes, this tube being charged with oil of a suitable nature for
preventing the electrolyte from creeping further along the conductor.
In other cases the vessel containing the intercepting medium may be of trough
shape into which a bight of the conductor dips. This trough may be divided
by a diaphragm dipping to a suitable depth into the intercepting medium, the
conductor passing beneath this; or a number of diaphragms may be used, and
if desired the conductor may be carried over and under alternate diaphragms.
Dated this the 30th day of January 1899.

JOB THOMAS NIBLETT and MALCOLM SUTHERLAND, Electrical Engineers, both
of 61, Chandos Street, Strand, London, W.C., 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:-

if desired the conductor may be carried over and under alternate diaphrams.
The diaphram may be in the form of a tube and surround one leg of the
bight of the conductor.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
-
I. In electrical apparatus the use of oil or other suitable liquid for preventing
the creeping of acid or other deleterious matter along electrical conductors.
II. The combination with an electrical conductor of a U-tube, through which
the conductor passes, and which contains oil or other suitable liquid, substantially
as, and for the purpose herein before described.
III. The combination with an electrical conductor of a trough containing oil
or other suitable liquid, into which a bight of the conductor dips, a diaphram
being interposed between the two legs of the said bight, substantially as herein-
before described.
IV. The combination with an electrical conductor of a trough containing oil
or other suitable liquid, into which two or more bights of the conductor dip,
diaphrams being interposed between adjacent legs of the bights, substantially
as hereinbefore described.
