Railway mechanical engineer . engthen-ins; the life of the tools. , HopPER FOR LOCOMOTIVES.—Firemenon big locomotives tind promise of lightened work in the rotat-able coal hopper that has been invented for engine invention is .<o planned that the coal is kept handy atthe firing deck, making it an easy matter for the firemen toreach the coal without shoveling from the rear of the tenderor using power apparatus. This special hopper is in the formof a great segmental tub, or drum, having a diameter that isthe approximate width of the tender. This drum is inclinedtoward the firing deck; it is so mounted on a ball-bearingcenter plate as to turn readily. In its outer wall are open-ings, one for each segment, through which the coal fallsIty gravity. As .soon as the coal is emptied from the segment,tiie brake that controls the drum is released. Naturallythe greater weight above the center of the drum makes itrotate, bringing the next loaded .segment into position.—Scientific Quick Opening Door in Front End Netting A FRONT end netting door, which may quickly be re-moved and replaced and which has sufficient area ofopening to facilitate thorough and rapid inspection oftlic spark, arrester and draft appliances, is shown in the illus-trations.
