Consequently all of their sea-going vessels were equipped with Westinghouse steam driven compressors ... So satisfactory was this practice that specifications for the four new boats, Excalibur, Exo- chorda, Exeter, and Excambion, included a similar ma- chine, but of greater capacity—150 cu. ft. displacement. A similar situation prevails with the Sinclair Navigation Company. Westinghouse compressors on many of their older boats have proved to be such a great convenience that they were specified for the new tankers Virginia Sinclair and Harry F. Sinclair. Among other outstanding cases are the recently built coast guard cutters Saranac and sister ships, and fleets of the following steamship companies: Matson, Isthmian, A. H. Bull, Dollar, Lukenbach, Hausteca, Consolidated Naviga- tion, Cities Service, and many other oil transportation and general shipping companies . . . Besides these hundreds of compressors on board ship, many are used on pile drivers, barges, etc., for harbor and dock maintenance work. Westinghouse steam driven compressors are compact self- contained units, occupy no floor space, as they can be readily attached to a column or bulk head. They are reliable and durable machines.
