By fixing a link ofthis chain to the floor of an or-dinary elevator-cage, and impel-ling the flexible chain by meansof a suitable wheel, driven byany motive-power whatever situ-ated at the bottom of the eleva-tor, it is easy to see that thechain will follow the cage wher-ever its guides will permit it torun. By joining the two ex-tremities of the flexible chain, itforms an endless chani of rodsmoving over two encaged lower wheel applies thepower, and the upper one actsas a simple pulley-wheel to ena-ble the chain to circulate. The Otis elevator is of thehydraulic type described else-where, the power being derivedfrom a hydraulic cyl
