NB AIR BRAKE AND SIGNAL HOSE CONNECTION. The George M. Newhall Engineering Co., Ltd., of Philadel-phia, Pa., are putting on the market a device designated as theNB air brake and signal hose connection. This was designedby E. D. Nelson, engineer of tests, Pennsylvania Railroad, andW. L. Brown, his assistant. The objects sought in designing this coupling were to over-come injury to the soft inner tube of the hose by the nipplesused in the ordinary form of mounting and to secure a methodof fastening the hose to the metal parts which would be freefrom the danger of a hose pulling off the fitting. The NB coupling is so designed as to avoid any contact ofthe metal parts with the soft rubber lining of the hose, and,therefore, preserves it against injury, thus leaving it free to per-form its function of sealing the hose structure against smallleaks, which eventually may
