Description: The 1877 model of the Lechner air mining machine revolutionized the coal mining industry. This image measures 8.5" by 11" (21.59 by 27.94 cm). In the 1870s, coal mining was slow and dangerous work. In a typical 12-hour day, productivity was only two tons per man. Much of the labor involved under-cutting--a miner had to lie on his side while digging a 6-inch-thick cut 4 feet deep across a 10-to-20-foot wide face. In 1876, a Columbus man, Francis Lechner, designed a chain-driven, air-powered machine that could undercut the coal mechanically, increasing daily productivity by one ton of coal per man. Lechner teamed up with Joseph Andrew Jeffrey and formed the Lechner Mining Machine Company in 1877. The Lechner coal-cutting machine eventually became a standard for the coal industry. The Columbus-based business, which in 1887 became known as the Jeffrey Manufacturing Company, was one of the city's most successful and long-lasting firms of the 20th century. View on Ohio Memory.

Description: Two 8" x 10" (20.32 x 25.4 cm) photographs document coal mining at the Sunday Creek Coal Mine Number 9 in Hocking County, Ohio. Organized in 1905, the Sunday Creek Coal Company operated dozens of mines in southeastern Ohio and West Virginia. Sunday Creek Coal Mine #6 in Millfield, Ohio was the site of one of the worst mining disasters in Ohio's history. On November 5, 1930, a buildup of methane gas exploded when the trolley the miners used to carry coal out of the mine produced a spark on the track. Eighty-two men were killed. Following the explosion, the mine closed for about a month. It reopened and operated until 1945. Tougher safety regulations were instituted in 1931 as a result of the Sunday Creek Coal Mine disaster.

Description: Dated ca. 1930-1943, this photograph shows two men shoveling coal into minecarts at the Blue Bell Mine near Strasburg, Ohio, in Tuscarawas County. A note on the reverse of the photograph reads "Close up surface coal mining. Blue Bell mine near Strasburg. S. H. Green. West High Ave., New Phila, N.K." The first European settlers recognized the value in Ohio's natural coal resources and in 1837 the first Geological Survey of Ohio studied the mineral resources of the state, especially coal. Ohio's canal system allowed for easy coal transportation for mining, and by the mid 1800s railroads and more advanced mining technologies advanced coal mining output in Ohio. Eventually, coal became the primary source of energy for electricity and fueled the many steel mills in the upper Ohio River Valley. This photograph is one of the many visual materials collected for use in the Ohio Guide. In 1935, President Franklin D. Roosevelt established the Works Progress Administration by executive order to create jobs for the large numbers of unemployed laborers, as well as artists, musicians, actors, and writers. The Federal Arts Program, a sector of the Works Progress Administration, included the Federal Writers’ Project, one of the primary goals of which was to complete the America Guide series, a series of guidebooks for each state which included state history, art, architecture, music, literature, and points of interest to the major cities and tours throughout the state. Work on the Ohio Guide began in 1935 with the publication of several pamphlets and brochures. The Reorganization Act of 1939 consolidated the Works Progress Administration and other agencies into the Federal Works Administration, and the Federal Writers’ Project became the Federal Writers’ Project in Ohio. The final product was published in 1940 and went through several editions. The Ohio Guide Collection consists of 4,769 photographs collected for use in Ohio Guide and other publications of the Federal Writers’ Project in Ohio from 1935-1939. View on Ohio Memory.

Description: This line of molding machine hoppers operating at Forest City Foundries in Cleveland, Ohio, in 1955, was produced by the Jeffrey Manufacturing Company of Columbus, Ohio. The overhead hoppers were filled with sand which was released by opening a clam shell valve. The sand was poured into a mold used to cast metal machine parts and recycled to make many other castings.

Description: This photograph depicts two adolescent or pre-teen boys with a Jeffery Manufacturing model 28A mining machine, ca. 1890-1910. The mining machine was used to undercut seams of coal, to allow for expansion after the coal seam was broken apart with explosives; at the time of its invention, this was the most time-intensive part of mining coal. Jeffery Manufacturing was located in downtown Columbus, near the intersection of Fourth St. and First Ave.; today, that site is occupied by the Ohioana Library and the State Library of Ohio.
