Object Details

Haworth, John

Description: This model was submitted to the U.S. Patent Office with the application for the patent issued to John Haworth, of Philadelphia, Pennsylvania, April 30, 1878, no. 203035.; The model represents a water motor having a vertical cylindrical water chute, within the lower end of which a small parallel-flow reaction turbine wheel is located. The wheel is carried on a shaft end to carry a worm gear from which the power of the motor is supplied. The motor is designed to operate a sewing machine, and the drive shaft carries a 2-bladed propeller fan for fanning the machine operator.; Motors of this type operating from the faucet pressure of city water systems were in use through the early 20th century. Their use was discontinued with the development of the small electric motor, cheap electric current, and the practice of installing individual meters in municipal water systems.; Reference:; This description comes from the 1939 Catalog of the Mechanical Collections of the Division of Engineering United States Museum Bulletin 173 by Frank A. Taylor.
