Frick Feed-Water Apparatus, Patent Model

This model was submitted to the U.S. Patent Office with the application for the patent issued to Jacob Frick, of Philadelphia, Pennsylvania, December 14, 1858, no. 22284. It is an improvement on the patent issued to Frick, March 18, 1856, no. 14449.
The model represents a combination of an air chamber, a safety valve, feed-water and blow-off cocks, a feed-water failure alarm, and a water jet just for extinguishing fires, all arranged in one instrument so that all can be secured to the boiler by one attachment only, thereby avoiding the necessity of piercing and “wounding” the boiler in several places.
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.
