RG Ross & Sons Steam Hammer

This single column steam hammer was built in 1907, for the opening of the Clyde Port Authority (Clyde Navigation Trust) repair workshops in Renfrew. When the works closed the hammer was transferred, with other machinery, to the Scottish Maritime Museum. It is an example of a steam hammer made to Rigby's patent by the leading maker of such machines, RG Ross & Sons at their Greenhead Engine Works in Glasgow. It was used to forge replacement parts for the Clyde Navigation Trusts's fleet of dredgers and hopper barges. Steam hammes consists of a cast iron base plate and the hammer body which carries a steam piston and hammer head. It was operated by pulling on the long metal lever on the right hand side. This released steam into the piston making the hammer head move down with great force. A trained operator could vary the pressure the hammer head exerted - some chose to show off their skills by borrowing a watch, placing it under the hammer and halting the hammer head a fraction above the glass face.

这台单柱式蒸汽锤（single column steam hammer）于1907年打造，用于苏格兰伦弗鲁（Renfrew）的克莱德港务局（Clyde Port Authority，即克莱德航运信托基金Clyde Navigation Trust）维修车间的启用仪式。该车间关停后，这台蒸汽锤与其他机械设备一同被移交至苏格兰海事博物馆（Scottish Maritime Museum）。此为采用里格比专利技术（Rigby's patent）的蒸汽锤典范，由该类设备的顶尖制造商——设于格拉斯哥格林黑德发动机厂（Greenhead Engine Works）的RG·罗斯父子公司（RG Ross & Sons）制造。该蒸汽锤曾用于为克莱德航运信托基金的挖泥船与料斗驳船船队锻造替换零件。该类蒸汽锤由铸铁底板与搭载蒸汽活塞及锤头的锤体构成。其操作方式为拉动右侧的长金属操纵杆，将蒸汽注入活塞，使锤头以强劲力道向下运动。受过专业训练的操作员可调节锤头的施压力度——部分操作员会通过展示技艺彰显实力：借来一块手表置于锤头下方，让锤头精准停在玻璃表盘上方极近处。数据来源：Objaverse 1.0 / Sketchfab
