By placing the buckets on theflywheel of an air compressor or a pump, the requisite motive force isat once obtained without the use of intermediate gearing. An instanceof this is the Riedler pumps of the Niagara Falls Water Works of these pumps consists of a duplex double acting Riedler made by 20 MACHINERY FOR METALLIFEROUS MINES. Messrs. Fraser & Chalmers. The plungers are iig in. diameter x 30 The capacity is 6,000,000 United States gallons per 24 hoursagainst a pressure of 70 lb. per square inch. The Pelton wheel is 12 , and consists of an extra heavy flywheel, upon which are boltedthe requisite number and sizes of waterwheel buckets. The wheel isdirectly connected on the crank-shaft, and is enclosed in a flanged steelcasing and runs at a speed of 75 revolutions per minute. For driving high-speed dynamos direct, the Pelton is
