First Undersea Craft to Carry Storage Battery Will Be Christened by Mrs. John Erye Sloane.
When the United States submarine L-8 (SS-48), the first in the world to carry the new Edison storage battery, is launched at Portsmouth Navy Yard, N.H., Mrs. John Eyre Sloane, daughter of the inventor, will crack the champagne bottle across her prow.
Mrs. Sloane, who yesterday accepted Secretary Daniels invitation to officiate at the christening, is the wife of a former assistant of Mr. Edison and now an inventor and an expert on aeronautics."
Somewhere along the line, she didn't christen the L-8 and the honor went to Miss Nancy Gill.
Mrs. Sloane finally got her chance 44 years later with the Thomas A. Edison (SSBN-610), on 15 June 1961.

She displays Lake's trademark watertight superstructure, with limber holes to allow the bow portion to flood quickly for a fast dive. Leonidas (1898-1922) is in the left background, with a gun installed on her forecastle. Round building in the right center is the dry dock pumphouse. Building 7 is in the right background.||Text i.d. via Peter Morrison.

|27k|| Simon Lake's L-8 (SS-48) (built by Portsmouth) shows his characteristic ship-type stern, with its horizontal chisel shape, which C & R preferred to E.B.'s much less buoyant one. The cylinder forward of the bridge houses a 3-in Mk IX gun. The bankruptcy of Lake's original company delayed construction of these boats, when completed, they embodied such war modifications as chariot bridge and retractable (housing) periscopes.|
Note the signal bell set into the keel forward. During WW I, such bevels were superseded by Fessenden oscillators, which used plates set into flooded tanks. The battery tanks were set above the two main ballast tanks, one below the torpedo room forward and one below the control room amidships.
Note that Lake subdivided his boats more completely than did E.B., with separate engine & motor rooms aft, and with a separate tiller flat abaft the after trim tank (which was abaft the motor room, connected to it by an access trunk). He concentrated pumps & other auxiliaries to the large space beneath the control room, rather than (as in E.B.'s design) along the propeller shafts abaft the motors. The two periscopes flank the retractable antenna mast. This class incorporated Lake's patented air lock abaft the conning tower.
