About the Book

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1909 Excerpt: ... from 5 to 6 cents less per ton than from flat-bottom cars by hand. Switching.--When coal is delivered in self-clearing cars and dumped into a hopper, tracks can be arranged so that cars can be handled by gravity, without the need of a switcher, thereby reducing the cost of operation. Two=pocket Plant, Single Track, Wood Structure.--Fig. 66 illustrates a two-pocket single-track McHenry coaling plant with dynamometer weighing device to each pocket so that the amount of coal taken by each tender can be recorded. Capacity 70 tons. Cost complete $4000 to $5500. Four=pocket Plant, Single Track, Wood Structure.--Fig. 67 illustrates a four-pocket, single-track McHenry coaling plant with weighing device to each pocket. Capacity 140 tons. Cost complete $8000 to $9500. In the two and four pocket plants the coal car is spotted over the hopper and dumped, the coal running by gravity into the boot, where it is hoisted by endless chain and bucket method to the pockets above. On the upper horizontal run the coal is scraped along the conveyor. Gates are provided to each pocket so that the coal may be dumped into any one desired by leaving the gate open. In the four-pocket plant the chains and buckets make an entire circuit round the house, the drive being set above the up-shaft end. The engine house with steam or gasoline power is placed a little beyond the coal structure, and a rope drive connects the engine with the main drive above. If desired, the mechanism can be motor driven direct or by pulley, thus dispensing with the engine house, when electric power can be obtained. The chain speed is 65 feet per minute and the power consumption about 12 to 15 horsepower. The space under the pockets may be boarded and used for storage purposes. Four-pocket, Three-track Plant, Woo...
