Inventions: Japheth's Favorites
The Hydraulic Ram
Japheth’s Stream
Pump is featured in Noah’s Boys in the City of Mother Earth, and
is a pump powered by the flow of the stream itself. Whether or not Japheth was its original first inventor, his
pump seems to have been an antediluvian predecessor of the modern hydraulic
ram. His pump was based on the
principle that air may be compressed like a spring, but that water is
incompressible, and conducts force.
History of the
Hydraulic Ram: The hydraulic ram has been named one of the 55 most
important inventions in the history of the world (People’s Cyclopedia,
1879). For more than 200 years, the hydraulic ram has been a major contributor
to improved health and sanitation, as well as to crop production, gardens, and
landscaping. While a manually controlled form of hydraulic ram was invented in
1772 (John Whitehurst of Cheshire, England), when the inventor Joseph
Montgolfier (more famed with his brother Jacques as the inventors of the hot
air balloon) added a one-way valve in 1796, it made the pump self-acting, and practically
a perpetual-motion machine. The
hydraulic ram quickly became popular, and by 1840 it was widely used in rural
America, especially in the form of Benson’s Patent Ram.
Modern Application
of the Hydraulic Ram: The hydraulic ram is widely used today as a
reliable, inexpensive, and environmentally safe, way to provide clean water for
livestock or operate water purification systems. It is especially advantageous in mountainous areas, or anywhere
else access to power is limited.
Hydraulic rams do not require electricity, can work continuously
whenever the stream is flowing, and do not require wind or sunshine.
Commercially Available
Hydraulic Rams: These
include the Fleming Hydro-Ram (www.theramcompany.com,
Lowesville, VA), which was developed in 1980 by Richard Fleming. This pump
requires as little as a 2-foot fall of water with a flow of 3 gallons per
minute in order to pump water as high as 20 feet. The basic design of the modern hydraulic ram, and a typical
application, is seen in the illustrations below. Other hydraulic ram manufacturers include Derkor (illustrated below, www.rampumps.net) and Gravi-chek (www.gravi-chek.com). A quick
internet search will reveal many hydraulic ram distributors, as well as books,
such as Don Wilson’s All About Hydraulic Ram Pumps, and articles
describing how to build your own.
The Noah’s Boys series emphasizes that man was deliberately
designed to be creative. Inventing
machines and new ways to meet the many needs and problems of the world is one
way to make Life an Exciting Adventure!
