[Mr. Judds solution is correct.—Ed.] i i i A New Brake Hanger. Editors : The inclosed print illustrates a brakehanger which I would like to have youropinion upon.

With this hanger you can increase brak-ing power and avoid sliding of will agree with me that somethingof this kind is needed for high-speedtrains. Peter ,i,,F. E. C. Ry. East Palatka, Fla. [There is so much to be said aboutbrake hangers, brake shoes, and their in-fluence upon and tendency to skid wheels,that we cannot discuss them at present inconnection with our correspondents de-vice; but, having in mind the results ofcarefully conducted experiments we areobliged to confess that we fear the intro-duction of a spring in a brake hangerwould not prevent the wheel from skid-ding. The fact that not a single flat wheel hasbeen removed from trains using the HighSpeed brake seems to indicate that, in-stead of causing flat wheels, it preventsthe
