Several years ago, Mr. Robert A. Cook described and illustrated in our Transactions a mechanical coke-drawer, patented in 1891 by Mr. Thomas Smith of the Thorncliff Iron Works, Sheffield, England, and first introduced in the United States in 1896, at the coking-plant of the Latrobe Coal Co., Latrobe,Pa. This machine has not received any very extended application in this country, although it was successfully used in two places for a number of years. The present paper describes a new and simpler machine, containing few wearing-parts, and capable of withstanding continued rough usage. Anything which tends to prolong the general use of bee-hive ovens will be welcome to those who are interested in cheapening the cost of producing coke in such ovens, especially if it provides satisfactory mechanical means, replacing the hard labor involved in drawing coke by hand with the old-fashioned " duck bill." The difficulty of finding efficient coke-drawers, especially during the summer season, and in the South, is notorious. Yet, notwithstanding the great improvements that have
