Bunker Hill Bridge is the only surviving Haupt truss bridge in the U.S. and one of only two surviving covered bridges in North Carolina. Patented in 1839, the Haupt truss featured diagonal braces spanning multiple panels, which was an attempt to eliminate the cross-strain found in lattice truss bridges. Although it was almost immediately eclipsed by the Howe truss and never reached the mainstream of covered bridge building, the Haupt truss is of interest for its association with Gen.
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.
Luebben Hay Baler - Historic Landmark of Agricultural Engineering. In 1892, Hugh Luebben from Sutton, Nebraska, with sons Melchior and Ummo built a mobile machine to produce round hay bales between two sets of rotating flat belts. They began manufacturing the baler in 1909 in Beatrice and later moved to Omaha, Nebraska. Allis-Chalmers purchased the patent in 1939 and eventually sold 77,200 "Roto-Balers." The Luebben baler made handling easier, improved hay quality, and reduced costs. The same basic design is used on modern large round balers.
In 1892, John H. Froehlich, Froehlich, IA, Mounted A Gasoline Fueled Internal Combustion Engine On A Traction Geared Frame And Used It To Power A Threshing Machine. A Change In Power Source Had Begun On North American Farms. In 1892, The Case Co., Racine, Wi, Built An Experimental Gas Traction Engine. In 1898 A Patent Was Issued To The Van Duzen Co. Cincinnati, OH, For A Gasoline Traction Engine. Huber Mnfg., Marion, Oh, Bought This Patent In 1898 And Produced 30 Prototype Units. In 1902, Hart-Parr, Founded By Charles W. Hart And Charles H.
Charles C. Fenno Of Grinnell, Ia, Patented The First Field Corn Silage Harvester On April 19, 1892. His Ground-Powered Machine Cut The Corn Plant And Fed The Tassel End First To A Rotary Cutter. Joseph Weigel Of Flandreau, Sd, Improved Fenno's Harvester In 1912 By Adding An Engine To Power The Cutter And By Feeding The Stalks Butt End First. Andrean And Adolph Ronning, Farmers Of Boyd, Mn Patented Further Improvements In 1915. In 1918 The American Harvester Co. Of Minneapolis, Mn, Began Manufacturing The Horse-Drawn Ronning Harvester Using Weigel's Patent Too.
Imagine a world without batteries. It would be a much different world, in which the automobile and the telephone would have developed differently and probably later, a world without many of the conveniences of modern life and without some of the necessities. The battery, ever smaller and more powerful, defines much of our modern comforts and advances. There were many scientific and technological advances on the way to those smaller and more powerful batteries.
Sometime in 1894, while his Great Lakes steamer W. P. Thew lay tied to a Cuyahoga River wharf in northeast Ohio, 48-year-old Capt. Richard P. Thew, failed farmer and hardware salesman, observed a railroad steam shovel take one clumsy scoop of ore after another from the heap on the wood docks and dump them into a hopper car sitting on nearby railroad tracks. He noticed that the shovel bucket’s teeth gouged the dock’s timbers and left much of the ore behind.
THE MISSISSIPPI RIVER STOOD AT THE CENTER, literally and figuratively, of the United States’s westward expansion during the nineteenth century. By far the most prominent name in taming the powerful river was James Buchanan Eads. From the 1830s through the 1850s this supremely capable engineer salvaged hundreds of wrecks with a series of ever-larger diving bells, gaining in the process an intimate knowledge of the river’s bottom.
Sometime in 1894, while his Great Lakes steamer W P. Thew lay tied to a wharf on the banks of the Cuyahoga River in northeast Ohio, Capt. Richard P. Thew whiled away many hours as men laboriously unloaded his iron ore cargo onto the wooden docks.
