Add to basketSafety at Sea. Submarine Signal Co. Boston, 1904 published by the Submarine Signal Co., 7.5x4.25", 28pp, occasional drawings and photos. Stiff wrappers. Provenance: Smithsonian Institution, and then the Library of Congress, with their fading rubber stamps on the front wrapper. The front wrapper is becoming detached, with the top and bottom third detached, the middle third is intact. That said, a VG copy. [++] "The Submarine Signal Company (SSC) was established in 1901 in Boston, MA, and was the first commercial enterprise organized to conduct underwater sound research and to develop equipment to be used for increasing safety of navigation." [++] WorldCat locates 7 copies of this work.[++] This was an interesting idea for 1904, it seems to me. Sound travels considerably faster and farther in the water than the air, but that of course is a little complicated, all depending on the sound source, the water temperature and pressure and other factors. In this proposal by the Submarine Signal Co. of Boston, the sound source was a bell produced for functioning underwater. Intriguing. Here's a short history of the company in abstract from the Acoustical Society of America meeting 2015: "The Submarine Signal Company (SSC) was established in 1901 in Boston, MA, and was the first commercial enterprise organized to conduct underwater sound research and to develop equipment to be used for increasing safety of navigation. The initial product line (prior to 1914) included underwater bells for shore based stations, buoys, and lightships, as well as encased microphones for sound detection on the ships. The bells were used for navigational and hazard warning purposes. In April 1912, future SSC President H. J. W. Fay had a chance meeting with Professor Reginald Fessenden at a Boston railroad station. This meeting led to an invitation for a Fessenden visit to SSC where upon Reginald so impressed company managers and engineers that SSC hired Fessenden consulting services to redesign their hydrophones. Based on this and later contributions to underwater sound products, H. J. W. Fay and R. A. Fessenden are two of the five named pioneers of the ASA award known as The Pioneers of Underwater Acoustics Medal . This presentation will discuss the formation and product lines of SSC through their formation till 1946 when they were merged with Raytheon Company.".
