em. Master mechanics and superintendents of equipment exclusively for heater coils. Great advances have beenmade in providing binding posts and special connectorsfor attaching the wiring. In former days heaters werefurnished with copper insulated leads soldered to thecoils. This necessitated making a splice to connect them,and the solder often softened from the heat. By attach-ing the ends of the coils direct to terminals furnishingadditional provision for connecting the outside wiring,troubles of this nature are avoided. Lightness of con-struction is obtained by using sheet-steel and othersheet-metal punchings instead of castings. A 600-volt portable cab heater with plug socket wasa special feature. This should be of great benefit forcars with motormens caps or in cases where trainoperation is employed. For shops and stations wall and floor type heatersare arranged for mounting in batteries so that anynumber of units may be employed. Improvements in thermostats included moulded insu-

SHOWN AT ATLAN1 of electric railways found plenty to occupy their atten-tion in the exhibits of car parts and car fixtures, spe-cialties and appliances. These included new types ofseats and seat parts, car trimmings, hardware, curtains,safety treads, as well as drawn steel and pressed-steelshapes and stampings. An anti-rattling and window-sash brake device of new design is arranged to retardthe downward movement of the sash and offer no resist-ance to the sash being raised. Two springs of differentstrength are used. In raising the sash a shoe com-presses the weaker spring and the window can be easilyraised. In lowering, the shoe automatically slides to aposition to compress the heavy spring. This increasesthe pressure and prevents the sash from falling. The display of car heating equipment included elec-tric heaters, switches, thermostats, etc. Improvementsin electric heater construction provided for ventilatedcores with a
