Abstract
Abstract This invention relates to a storage battery provided with an improved liquid feeding device and gas exhausting device. This storage battery is formed of a storage battery provided with a monoblock battery container containing such battery elements as plates and separators for each cell and with a novel liquid feeding device and gas exhausting device in a lid. The liquid feeding device has a liquid supplying part communicating with a water tank or an air source and with each cell through an electrolyte level setting tube. The gas exhausting device is formed by containing a valve which closes the passages into each cell at the time of feeding the liquid but can open the above mentioned passage when oxygen and hydrogen gases generated within the storage battery are to be replaced with air fed into each cell from the liquid supplying part. The storage battery of the present invention, by the above mentioned liquid feeding device and gas exhausting device, enables liquid to be safely fed to a fixed level without an explosion within the battery and also allows the operation to be carried out very simply and positively.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
279 words
A storage battery adapted to be supplied with air from an air source and water from a water supply tank, the battery comprising: a monoblock battery container having a plurality of storage cells arranged therein and a lid covering said cells, said lid being provided with liquid supplying means for use in supplying air and water to said cells and gas exhausting means for use in exhausting oxygen and hydrogen produced in said cells from said cells; said liquid supplying means including a slender section provided within said lid; a plurality of electrolyte level setting tubes arranged in communication with said slender section each extending in a downward direction from the back of said lid into a respective one of said cells; a plurality of gas passageways, each arranged in communication with a respective one of said cells; said gas exhausting means including a plurality of valves, each arranged within a respective gas passageway; means adapted for supplying air from the air source into each of said cells through said liquid supplying means and said electrolyte level setting tubes and causing an exhaust flow of oxygen and hydrogen gas from within said cells to escape through said gas exhausting means into the atmosphere; means adapted for discontinuing the flow of air into said cell and the exhaust of the exhaust gases and subsequently to feed water from the water supply tank into each of said cells through said liquid supplying means and said electrolyte level setting tubes; and, means adapted for supplying air from the air source into said gas exhausting means so as to cause the closure of said valves when water is being supplied to said cells.
Claim 2
Dependent Claim
279 words
A storage battery adapted to be supplied with air from an air source and water from a water supply tank, the battery comprising: a monoblock battery container having a plurality of storage cells arranged therein and a lid covering said cells, said lid being provided with liquid supplying means for use in supplying air and water to said cells and gas exhausting means for use in exhausting oxygen and hydrogen produced in said cells from said cells; said liquid supplying means including a slender section provided within said lid; a plurality of electrolyte level setting tubes arranged in communication with said slender section each extending in a downward direction from the back of said lid into a respective one of said cells; a plurality of gas passageways, each arranged in communication with a respective one of said cells; said gas exhausting means including a plurality of valves, each arranged within a respective gas passageway; means adapted for supplying air from the air source into each of said cells through said liquid supplying means and said electrolyte level setting tubes and causing an exhaust flow of oxygen and hydrogen gas from within said cells to escape through said gas exhausting means into the atmosphere; means adapted for discontinuing the flow of air into said cell and the exhaust of the exhaust gases and subsequently to feed water from the water supply tank into each of said cells through said liquid supplying means and said electrolyte level setting tubes; and, means adapted for supplying air from the air source into said gas exhausting means so as to cause the closure of said valves when water is being supplied to said cells.
Claim 3
Dependent Claim
93 words
A storage battery as defined in claim 1 further comprising: a water supply branch tube adapted for being coupled with the water supply tank and the air source through a water supply main tube, said water supply branch tube serving to interconnect the water supply main tube with said liquid supply means; and, a water exhaust branch tube adapted for being arranged in communication with the water supply tank through a water exhausting main tube, said water exhaust branch tube serving to interconnect said liquid supply means and the water exhausting main tube.
Claim 4
Dependent Claim
80 words
A storage battery as defined in claim 1 wherein: said gas exhausting means includes a plurality of chambers provided within the lid, each chamber being associated with a respective one of said cells; each of said valves is a spherical valve and is arranged within a respective one of said chambers; and, further comprising a gas exhausting branch tube arranged in communication with each of said chambers and adapted to be arranged in communication with a gas exhausting main tube.
Claim 5
Dependent Claim
60 words
A storage battery as defined in claim 1 further comprising a plurality of guard tubes, each arranged around and concentric with a respective one of said electrolyte level setting tubes, said guard tubes being provided on the back of said lid and being partially opened at its lower end and provided with a plurality of holes in its side walls.
Claim 6
Dependent Claim
37 words
A storage battery as defined in claim 3 further comprising a partition wall provided at the end of said slender section of said liquid supplying means which is arranged in communication with said water exhausting branch tube.
Claim 7
Dependent Claim
58 words
A storage battery as defined in claim 1 further comprising means adapted for supplying air from the air source to said cells after the supply of water has been completed, the air being supplied through said liquid supplying means so that any water remaining in the passage of the water supply and possibly containing sulfuric acid is cleansed.
Claim 8
Dependent Claim
175 words
A storage battery adapted to be supplied with air from an air source and water from a wateR supply tank, the battery comprising: a monoblock battery container having a plurality of storage cells arranged therein; liquid supplying means for use in supplying air and water to said cells; gas exhausting means for use in exhausting oxygen and hydrogen produced in said cells from said cells; means adapted for supplying air from the air source to said cells through said liquid supplying means, for causing the exhaust of oxygen and hydrogen from said cells through said gas exhausting means; means adapted for discontinuing the flow of air into said cells and the exhaust of the exhaust gases and subsequently to feed water from the water supply tank into each of said cells through said liquid supplying means; and, means adapted for supplying air from the air source into said gas exhausting means so as to cause the blocking of the exhaust of gases through said gas exhausting means when water is being supplied to said cells.
