Ackley Bridge is an excellent example of a multiple kingpost truss and a noteworthy early example of covered bridge preservation efforts in the United States. Built in 1832 by Joshua Ackley (b.1805) and Daniel Clouse (b.1812), Ackley Bridge originally spanned Enslow’s Branch of Wheeling Creek between Greene County and Washington County in Pennsylvania, where it carried traffic for over a century.

In 1894, Dr. John Harvey Kellogg and his brother, Will Keith (W.K.) Kellogg, were making a granola type cereal for their patients in the Battle Creek Sanitarium, a general health facility in Michigan. This granola cereal was made from wheat that was boiled, rolled into a sheet, toasted, and ground. They accidentally left a batch of boiled wheat stand overnight before passing it through the rolls. The individual grains were subsequently pressed into flakes which were toasted to form the first flaked cereal. Two years later, W.K. Kellogg made the first corn flakes.
The concept of once-over mechanical, as opposed to multiple-pick hand or experimental multiple-pick machine harvesting, represented a major break-through in the practice of producing vine fruit such as pickling cucumbers. In the 1950s the cost of hand harvesting was as high as 50% of the production cost. Once-over mechanical harvesting, coupled with increasing plant population, reduced this cost to 25% thereby making production economically viable.
A Historic Landmark of Agricultural Engineering in 1834 Near the Village of Climax, Michigan, Hiram Moore and John Hascall Built and Put Into Practical Use the First Successful Grain Combined Harvester - Thresher Which was Patented June 28, 1836. This Achievement was a Significant Contribution to the Development of American Agriculture Dedicated by the American Society of Agricultural Engineers 1978
Designated A Historic Landmark Of Agricultural Engineering The Massey-Harris No. 20 was the First Commercially- Successful Self-Propelled Combine Used to Harvest Small Grains Under a Wide Variety of Conditions, World-Wide. Engineered By Thomas Carroll, Chief Engineer, Aided by Robert Ashton and Albert Luke, Principal Assistants, it was First Marketed in 1938 by the Massey-Harris Company. This Combine Opened a New Era an Farm Mechanization and Revolutionized the Grain Harvesting Process. Forty-Four Years Later, This Same Harvesting Principle Continues to be Used Throughout the World.
Established in 1907, the American Society of Agricultural Engineers (ASAE) was managed by volunteers. In 1925, local editor Raymond Olney was named secretary, thus establishing ASAE in this area. By 1969, with over 7,000 members in 100 countries, an ASAE building was constructed at this site in St. Joseph, Mi. In 2005, ASAE became ASABE to recognize the importance of biology in the profession. ASABE collects and maintains the unique body of knowledge for the agricultural/biological engineering profession.
"Who in Europe, or in America for that matter, knows that Kansas City is one of the loveliest cities on earth? [...] the residential section is a masterpiece of city planning [...]; Few cities have been built with so much regard for beauty."
he Automatic Temperature Control System was named as a Historic Mechanical Engineering Landmark in 2008. Warren S. Johnson came up with the idea for automatic temperature control while teaching at Normal School in Whitewater, Wisconsin in the 1880's. Originally, janitors would have to enter each classroom to determine if it was too hot or cold and then adjust the dampers in the basement accordingly. Johnson sought a way to end, or at least minimize the classroom interruptions of the janitors and increase the comfort level of the students.
The two 3,500-hp steeple compound Unaflow steam engines powering the S.S. Badger represent one of the last types of reciprocating marine steam engines. Built by the Skinner Engine Company, most Unaflow engines are single expansion. These feature tandem high- and low-pressure cylinders separated by a common head. The Badger's four Foster-Wheeler Type D marine boilers, which supply 470-psig steam to the engines, are among the last coal-fired marine boilers built.
The Second Street Bridge is a simply ornamented, wrought-iron structure. It is 18 feet wide and spans 225 feet over the Kalamazoo River. It was built to replace a dilapidated wooden bridge that had served the area for nearly 50 years.
The bridge is anchored to fieldstone abutments on each shore, and the deck is composed of wood beams. Iron lattice work provides structural stability and iron finials on the end posts provide aesthetic appeal. It includes a wooden pedestrian walkway.
