NEW MACHINE FOR CLEANING FLUES. A new machine for cleaning flues has recently been in-stalled at the South Tacoma shops of the Northern PacificRailway, which is similar in principle to those in use at theTopeka shops of the Atchison, Topeka & Santa Fe Railwayand the Angus shops of the Canadian Pacific Railway, theconstruction and operation of which were fully described andillustrated on page 221 of the American Encineeb and Rail-road Journal, June, 1904. The advantages of these machinesare that they will clean a larger number of flues at one timeand clean them quicker than by other methods. As the flues. NEW MACHINE FOR CLEANING FLUES. are rolled under water the noise is greatly reduced. The costof handling the flues in and out of the machine is reduced toa minimum. The overhead works have been done away with on the ma-chine at South Tacoma, making it more compact and con-venient. Instead of having only two sprocket chains, one ofwhich is adjustable to suit the length of the flues, there arefour sprocket wheels mounted on a shaft on each side of thetub, or tank, as shown in the illustration. These sprocketwheels are so placed that the chains will clear the sides and Comparative Safety of Travelin United States and Abroad.—I have collected some data fromother sources, and have, as far aspossible, verified it.
