Claim 1
Independent Claim
224 words
An electric storage battery comprising a closure including a battery cover sealed with a battery casing and gas venting means to vent only gases out of said closure, said gas venting means comprising a gas cooling chamber including a plural of divided chamber portions communicating with respective cells and said electric storage battery, so as to receive gases from said cells and communicating with each other through openings provided adjacent to the tops thereof, said gas cooling chamber having a water returning lateral port provided at the bottom of said divided chamber portions; a gas filter chamber provided adjacent to said gas cooling chamber to communicate with said gas cooling chamber through an opening in the wall of said gas cooling chamber at the top thereof and having an explosion-proof gas filter disposed in said gas filter chamber so as to vent said gases therethrough; and a labyrinth chamber provided to vertically move through a tortuous path gases together with electrolyte mist and water steam and having an inlet through which said gases together with said electrolyte mist and said water steam are introduced into said labyrinth chamber and an outlet through which said gases and the remaining water steam are introduced into said gas cooling chamber, said labyrinth chamber further having an electrolyte returning port provided at the bottom of said labyrinth chamber.

An electric storage battery as set forth in claim 1, and wherein said gas cooling chamber has a bottom inclined toward the point where said water returning port is provided.
Claim 4
Dependent Claim
29 words
An electric storage battery as set forth in claim 1, and wherein said labyrinth chamber has a bottom inclined toward the point where said electrolyte returning port is provided.
Claim 5
Dependent Claim
51 words
An electric storage battery as set forth in claim 2, said gas cooling chamber further having a protecting cylindrical cover suspended from the top wall of said gas cooling chamber so that a lower opening of said protecting cylindrical cover covers said water returning lateral port of said gas cooling chamber.
Claim 6
Dependent Claim
54 words
An electric storage battery as set forth in claim 1, said gas cooling chamber further having a cylindrical portion provided at the bottom of said gas cooling chamber and closed at the bottom of said cylindrical portion, and wherein said water returning lateral port is provided in the side wall of said cylindrical portion.
Claim 7
Dependent Claim
29 words
An electric storage battery as set forth in claim 1, and wherein said explosion-proof gas filter is disposed in a downward manner so as to vent said gases downwardly.
Claim 8
Dependent Claim
