Jeffrey Glass Plate Negatives
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.
