An explosion-proof vent barrel having a tubular body, an electrolyte splash baffle and an electrolyte drain funnel molded integrally with one another, there being a porous flame-arresting disc telescoped into the body. Three barrels are ganged on a common frame which protects the flame-arresting discs against dirt and grease. In one embodiment, the underside surface of the frame is formed with a shallow channel to permit positive venting of the gases which diffuse through the arrestor discs. In another embodiment, both the discs and barrels are maintained in closely spaced relation to the underside of the frame for defining a positive escape area about substantially the entire periphery of the disc. In each instance, the depth of the positive vent escape area does not exceed 0.015 inches so as to permit positive venting while retarding the entrance of a flame into the space between the disc and frame.

An explosion-proof vent for closing the cell opening of a storage battery comprising a top frame plate and a tubular body releasably mounted in depending fashion from said top plate, said tubular body being molded of plastic for sealing engagement in said cell opening, said body defining a compartment with an aperture therein to permit gas from within said battery cell to flow into said compartment, a disc made of porous material interposed between an upper end of said body and said frame for covering the upper end of said body compartment, and means for maintaining a spatial separation of less than 0.015 inches between said top frame plate and at least a portion of said disc for allowing gases within said compartment to readily escape through said disc while retarding the entrance of a flame into the space between said frame plate and disc.
