Excerpt: ...on the ordinary mixture. The charging of briquettes was begun with a percentage of 25 per cent., and was carried up to 100 per cent. The following is the record of the results: RESULTS OF WORKING BRIQUETTES AT THE CRANE FURNACE Quantity of Phos- ManDate Briquette Tons Silica phorus Sulphur ganese Working Per Cent. January 5th 25 104 2.770 0.830 0.018 0.500 January 6th 37 1/2 4 1/2 2.620 0 740 0.018 0.350 January 7th 50 138 1/2 2.572 0.580 0.015 0.200 January 8th 75 119 1.844 0.264 0.022 0.200 January 9th 100 138 1/2 1.712 0.147 0.038 0.185 On the 9th, at 5 P.M., the briquettes having been nearly exhausted, the percentage was dropped to 25 per cent., and on the 10th the output dropped to 120 tons, and on the 11th the furnace had resumed the usual work on the regular standard ores. These figures prove that the yield of the furnace is considerably increased. The Crane trial was too short to settle the question to what extent the increase in product may be carried. This increase in output, of course, means a reduction in the cost of labor and of general expenses. The richness of the ore and its purity of course affect the limestone consumption. In the case of the Crane trial there was a reduction from 30 per cent. to 12 per cent. of the ore charge. Finally, the fuel consumption is reduced, which in the case of the Eastern plants, with their relatively costly coke, is a very important consideration. It is regarded as possible that Eastern furnaces will be able to use a smaller proportion of the costlier coke and correspondingly increase in anthracite coal, which is a cheaper fuel in that section. So far as foundry iron is concerned, the experience at Catasauqua, Pennsylvania, brief as it has been, shows that a stronger and tougher metal is made. Edison himself tells an interesting little story in this connection, when he enjoyed the active help of that noble character, John Fritz, the distinguished inventor and pioneer of the modern steel industry...
