Schutte Injector, Patent Model

This injector was submitted to the U.S. Patent Office with the application for the patent issued to Louis Schutte, of Philadelphia, Pennsylvania, February 9, 1892, no. 468698.
This is a double-tube injector in which water is delivered by one set of tubes, or nozzles, generally known as the lifting tubes into another set generally known as forcing tubes through which the water is forced into the boiler. The peculiar feature of this injector is a means of increasing or reducing the area of the opening of the steam nozzle of the lifting tubes, by which the quantity of water discharged by the injector is controlled without in any way interfering with the operating mechanism for starting and stopping the injector.
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.
