Washing Machine, Driven by Electric Motor
OTHER SMALL POWER DEVELOPMENTS
Mr. John T. McDonald, who has a farm about five miles from Delhi, Delaware county, N. Y., some ten years ago began making good use of a power development from a small stream on his farm. He lights his house and buildings, runs saws, grinders and various machines in a little shop on rainy days and in the winter. His [dam was made from stone and earth] from the nearby fields and cost very little. It forms a pond, covering, when full, about four and one-half acres of land. The pond is well stocked with trout and other fish, and each winter Mr. McDonald cuts about 500 tons of ice from it. Mr. McDonald turns on the water at his dam by means of an electric switch at the house and regulates the voltage also in a similar manner. From the pond the water is led through a hydraulic race, or canal, about 900 feet long, to one of the farm buildings where the waterwheels are installed. The head, or fall, at this point is about 15 feet and there are three waterwheels of the turbine type: one that develops 25 horsepower, another that develops 6 horsepower and a third that develops about 3 horsepower. The large wheel is used to run a sawmill and feed mill. The 6-horsepower wheel drives an electric generator, or dynamo, which furnishes the electric lights, and also electricity for driving the small motors about the place. The 3-horsepower wheel runs the small saws, machine tools, etc., in Mr. McDonald’s shop.
A few miles east from Mr. Van Wagenen’s farm in Schoharie county is another small power development owned by Mr. Frank Caspar. He has installed two waterwheels on a small creek and uses the power from them to drive the machinery in a table and furniture factory. He has another small waterwheel of the turbine type driving a little dynamo which generates electricity for electric light. Mr. Caspar lights his factory buildings, his home, a neighboring church and the main street in the village with electricity from this little dynamo. An ingenious device of his own invention makes it possible to start and stop the power from the house by simply pulling a wire which operates a valve in a small water pipe, from which water under pressure is let into a hydraulic cylinder. This causes the piston of the cylinder to rise, and the piston being directly connected to a gate in the water pipe inlet, allows the water to flow into the waterwheel. When it is desired to stop the plant, a pull on the companion wire causes the reverse operation to take place and the power is shut off.
Farm Power Development of John T. McDonald,
Delaware Co., N. Y.
Near the village of Berlin, in eastern Rensselaer county, N. Y., there is a small power development owned by Mr. Arthur Cowee. His source of power is a small trout brook which flows through the farm. Mr. Cowee is a producer of fancy gladiolus bulbs, on a large scale. His principal power development, consisting of a 36-inch impulse waterwheel, under a pressure due to a fall of about 210 feet, is used mostly for the purpose of operating a circular saw and other machinery connected with a sawmill. The water is diverted from the natural channel of the brook at a considerable distance from the place where the waterwheel is installed and is carried in an artificial channel, about four feet wide and three feet deep, around the side of the hill, where it runs into a shallow basin which has been excavated by Mr. Cowee at a suitable location. By means of this basin, or artificial pond, practically all of the flow of the brook may be stored during the night and used to operate the waterwheel during the day. In this manner the full power value of the brook is realized. There is a ten-inch, cast-iron pipe line, about 1680 feet long, which runs from the pond down the side of the hill to the waterwheel. This pipe line was placed under ground from three to four feet in order to avoid freezing in the winter. Mr. Cowee estimates that the development, including the diverting dam and canal, pond, pipe line, waterwheel, circular saw and accessories, cost him a total of about $7000. He states that he can saw about 4000 feet of lumber in a day with this power.
In addition to this development, Mr. Cowee also has a small impulse waterwheel in his bulb house. This wheel is operated by water furnished from the system of the local water company. It is directly connected to a small electric generator which furnishes electricity sufficient for 157 sixteen-candle-power carbon-filament lamps which are installed throughout the bulb house. The generator does not produce enough electric current to run all of these lights at the same time, but it will operate as many as forty-five or fifty lights at one time, which is all that is necessary to meet the requirements.
Mr. D. F. Paine of Wadhams, Essex county, N. Y., has a dam at the outlet of Lincoln pond. The water surface, when the pond is full, is about twelve feet above the normal and spreads over an extensive tract of low, marshy land. The pond thus formed is about three miles long and from one-quarter to three-quarters of a mile wide. The water is conducted from the dam to the penstock, a distance of about a mile and a half, securing a fall of 320 feet. At this point Mr. Paine has constructed a power house, where he generates electricity which he transmits to Mineville for use in the mines. This power is transmitted a distance of about eight miles.
