The patent says: This invention relates to water-wheels of the impact or Pelton type. [It provides] a wheel with buckets that will yield under the impact of the water-jet in order to relieve the wheel from the jar and strain caused by the powerful jet striking the buckets as they come successively in line with it and also increase the efficiency of the wheel. [Buckets are] pivotally secured to the wheel and [have] a cushioning device [e.g.] springs, [so they] yield somewhat when struck by the waterjet and impart the energy of said jet to the wheel in part by the recoil of said cushioning device [so that the] parts of the wheel which are rigid and are rigidly secured to the shaft will be relieved [of some] shock.
