Driggs-Seabury Ordnance Company was founded by William H. Driggs and Samuel Seabury, both US Navy officers, circa 1898, originally to produce guns for the US Army and US Navy designed by the partners. Driggs-Seabury was preceded by Driggs-Schroeder, a series of weapons designed by Driggs and Seaton Schroeder in the late 1880s and produced by the American Ordnance Company in the 1890s. Although Seabury died in 1902, followed by Driggs in 1908, the company continued under the leadership of Louis Labodie "L. L." Driggs until 1925. The company manufactured motor vehicles 1913-15 and 1921-25, but sold its weapons production and plant in Sharon, Pennsylvania to Savage Arms in a 1915 merger.〔(Poor’s Manual of Industrials, 1916, Vol. 7, New York: Redmond & Co., pp. 1722-1726 )〕〔(Unofficial Savage Arms company history )〕〔(Official Savage Arms company history )〕 Under Savage Arms, the Sharon plant made Lewis guns in World War I. Dropping the Seabury name, Driggs was reconstituted as a motor vehicle manufacturer in New Haven, Connecticut in 1921, confusingly named “Driggs Ordnance & Manufacturing Corporation”. Driggs folded for good in 1925. ==Weapons== Weapons produced by Driggs-Seabury included: *3-inch gun M1898 (aka 15-pounder),〔(Lohrer, George L. ''Ordnance Supply Manual'', U. S. Ordnance Dept., Washington: Government Printing Office, 1904, pp. 295-300 )〕 a coast defense weapon for the Army on a retractable "masking parapet" carriage, also made by Driggs-Seabury. 120 guns and carriages were built. It was later used as the basis for the 3-inch Gun M1918, an anti-aircraft weapon. With the bankruptcy of Driggs-Seabury, the seacoast weapons were removed from service in the early 1920s. *US Navy 3"/23 caliber gun Mark 13 during World War I. This had a semi-automatic horizontal sliding breech block. In this case semi-automatic means the breech opens and the cartridge is ejected on firing, ready for the next round to be loaded manually.〔(DiGiulian, Tony 3"/23 gun at Navweaps.com )〕 *The Navy 6-pounder Mark 11 and 3-pounder Mark 14 were made by Driggs-Seabury.〔Campbell, p. 147〕 *Two 6-pounder Driggs-Seabury guns were adopted by the US Army and designated the M1898 and M1900.〔(Lohrer, George L. ''Ordnance Supply Manual'', U. S. Ordnance Dept., Washington: Government Printing Office, 1904, pp. 282-295 )〕 References to Marks II and III Driggs-Seabury weapons appear to describe earlier Driggs-Schroeder weapons manufactured by American Ordnance, possibly similar to the Navy Marks 6 and 8.〔(DiGiulian, Tony US 6-pounder guns Mks 1-13 )〕〔Campbell, p. 147〕 Some of these weapons were used at coastal forts in limited quantities around 1900, and 12 were at Fort Ruger, Oahu, Hawaii 1915-19 under the Land Defense Project on "parapet" or "rampart" mounts which allowed a wheeled carriage to be fixed to a pintle mount.〔Berhow, pp. 188-189〕 *A 3.2-inch field gun, possibly the M1897.〔(Blueprint for a Driggs-Schroeder 3.2-inch gun from Winchester Repeating Arms Company, at the Buffalo Bill Center of the West )〕〔()〕〔(Scientific American Vol. 79, Issue 6, article on the 3.2-inch Driggs-Seabury field gun )〕 *The breech mechanism for the US Navy 3"/50 caliber gun Mark 5.〔(DiGiulian, Tony, 3-inch gun Marks 2, 3, 5, 6, and 8 at Navweaps.com )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Driggs-Seabury」の詳細全文を読む スポンサード リンク
