Bucket elevators are used to lift grain to a distributor or consignor, from which it falls through spouts and/or conveyors and into one or more bins, silos, or tanks in a facility.
As grain is emptied from bins, tanks, and silos, it is conveyed, blended, and weighted into trucks, railroad cars, or barges for shipment.
[2] Both necessity and the prospect of making money gave birth to the steam-powered grain elevator in Buffalo, New York, in 1843.
It stood at the intersection of two great all-water routes; one extended from New York Harbor, up the Hudson River to Albany, and beyond it, the Port of Buffalo; the other comprised the Great Lakes, which could theoretically take boaters in any direction they wished to go (north to Canada, west to Michigan or Wisconsin, south to Toledo and Cleveland, or east to the Atlantic Ocean).
If Buffalo had not been there, or when things got backed up there, that grain would have been loaded onto boats at Cincinnati and shipped down the Mississippi River to New Orleans.
They still relied upon techniques that had been in use since the European Middle Ages; work teams of stevedores use block and tackles and their own backs to unload or load each sack of grain that had been stored ashore or in the boat's hull.
Thanks to the historic Dart's Elevator (operational on 1 June 1843), which worked almost seven times faster than its nonmechanized predecessors, Buffalo was able to keep pace with—and thus further stimulate—the rapid growth of American agricultural production in the 1840s and 1850s, but especially after the Civil War, with the coming of the railroads.
Because of the money to be made in grain production, and of course, because of the existence of an all-water route to get there, increasing numbers of immigrants in Brooklyn came to Ohio, Indiana, and Illinois to become farmers.
Through this loop of productivity set in motion by the invention of the grain elevator, the United States became a major international producer of wheat, corn, and oats.
[1] In the early 20th century, concern arose about monopolistic practices in the grain elevator industry, leading to testimony before the Interstate Commerce Commission in 1906.
[3] Today, grain elevators are a common sight in the grain-growing areas of the world, such as the North American prairies.
Larger terminal elevators are found at distribution centers, such as Chicago and Thunder Bay, Ontario, where grain is sent for processing, or loaded aboard trains or ships to go further afield.
In a nascent trend, some of the city's inactive capacity has recently come back online, with an ethanol plant started in 2007 using one of the previously mothballed elevators to store corn.
In the early 20th century, Buffalo's grain elevators inspired modernist architects such as Le Corbusier, who exclaimed, "The first fruits of the new age!"
The classic grain elevator was constructed with wooden cribbing and had nine or more larger square or rectangular bins arranged in 3 × 3 or 3 × 4 or 4 × 4 or more patterns.
The loss of the grain elevators from small towns is often considered a great change in their identity, and efforts to preserve them as heritage structures are made.
For example, in 1961, 1,642 "country elevators" (the smallest type) were in Alberta, holding 3,452,240 tonnes (3,805,440 short tons) of grain.
In 2017, the United States had 0.88 cubic kilometres (25 billion US bushels) of storage capacity, a growth of 25% over the previous decade.
[5] The city of Buffalo is not only the birthplace of the modern grain elevator, but also has the world's largest number of extant examples.
In the early pioneer days of Western Canada's prairie towns, when a good farming spot was settled, many people wanted to make money by building their own grain elevators.
In the mid-1990s, with the cost of grain so low, many private elevator companies once again had to merge, this time causing thousands of "prairie sentinels" to be torn down.
