26 • ROCK products • July 2015 Before there was Rock Products, there was Cement & Engi- neering News. Founded in July 1896 by William Seafert, the journal set out to serve a fledgling cement industry whose primary work involved the construction of sidewalks and foundations. Cement & Engineering News would be purchased by and merged into Rock Products almost 20 years later. In the premiere issue, Seafert proposed to, "invade the field, in the interest of the cement trade and its kindred indus- tries…we shall endeavor to bring the producer and consum- er closer together, to their mutual advantage." When founded, the magazine had little to work with. In 1896, portland cement production in the U.S. amounted to 1,543,023 bbls, or about 290,000 tons, valued at $2.4 mil- lion; this was about 56 percent higher than 1895. There were 26 plants operating in 10 states, with the majority concen- trated in Pennsylvania and New York. More than 1 million bbls of the country's output came from Lehigh County, Pa., and Phillipsburg, N.J. Imports of portland cement in 1896 were about 3 million bbls, nearly twice the American output.

At the turn of the century, all of the following equipment was in wide use in the rock products industry: steam shovels; draglines; slackline cableways; drag scrapers; centrifugal pump, bucket ladder, and clamshell dredges; and hydrau- licking. O&K introduced the first bucket dredger in 1901, made completely out of wood. Some of the companies developing new technology for the industry are still around today. Emil Deister built his first ore-separating table in his basement and took his invention to Arizona, where he begged space from mill owners for its demonstration. Successful and armed with orders for the new equipment, Emil returned to Fort Wayne, Ind., to set up business in 1906, as the Deister Concentrator Co. In 1912, Emil sold his interests in Deister Concentrator Co. and es- tablished Deister Machine Co. Inc. Deister Machine Co. began manufacturing operations at 1933 East Wayne Street in Fort Wayne, Ind., its current loca- tion. The original building, a 5,500 sq.-ft. plant, is still in ac- tive use amidst a total operation that today spans more than Rock Products 120 th Anniversary In This Special Year-Long Series Celebrating Our 120th-Year Milestone, Rock Products Presents A History Of The Aggregates Industry.
