The Southern leaves no stone unturned to point out theadvantages to the country below the Potomac and Ohio. Thewall space is occupied by pictures, flanked by sheaves of grain. Usefulness of Retaining Rings 353. New Exhaust Pipe American Enijincer and Railroad Journal, Sep., 1901, p. J. B. Barnes, Superintendent Motive Power of theWabash Railroad, has designed a new locomotive exhaustpipe and an arrangement of front end appliances, of the per-formance of which he speaks very highly. His record showsa substantial reduction in back pressure, a good effect on thefire and an important saving in coal. He reports a savingof one ton of coal in runs of 100 miles over former practice,as a rough comparative figure. Twelve of liis engines havebeen fitted with these pipes, including several different typesin different classes of service, and they appear to be doingequally well in The exhaust pipe has a bridge 12 ins. high, in the centerof which a long spindle is screwed. On the top of the spindlean inverted cone is placed. It rests on a shoulder on thespindle and on its top face a spider is placed, with in section, reaching to the sides of the nozzle. Thewhole is secured by a key driven through a slot in the top of thespindle. To vary the size of the opening different cones andspiders are used, the nozzle diameter remaining unchanged. The object of this arrangement is to pass the steam outof the nozzle through an annular opening without diminish-ing the size of the opening. It provides means for issuingthe steam in a hollow stream of large diameter, causing lessback pressure, and it appears to increase the entraining ac-tion of the jet. As shown by indicator cards, the back pres-sure is less than with the ordinary nozzle and the draft effectseems to be very satisfactory, as there is no trouble in keej)-ing fires and front ends
