After the bond was soldered, it was formed into the shapeof a double-U to provide for expansion and contraction, orother longitudinal motion, of the rail. The result is a veryshort bond with abundant contact area, and a flexible portionthat will readily provide for extreme requirements. The bonds are applied from the web of the rail to the joint-plate, and from the joint-plate to the web of the rail, usingboth plates

The result is a veryshort bond with abundant contact area, and a flexible portionthat will readily provide for extreme requirements. The bonds are applied from the web of the rail to the joint-plate, and from the joint-plate to the web of the rail, usingboth plates and four bonds per joint. The application is madeby means of soldering to the rail. The surfaces are first thor-oughly cleaned by means of a sand blast. THE OPERATIVE EXHIBITS OF THE WESTINGHOUSE TRAC-TION BRAKE COMPANY AT LOUISIANA PURCHASEEXPOSITION The various brake and coupler exhibits of the Westinghousecompanies in the Palace of Transportation at the St. LouisExposition are especially noteworthy in their feature of com-. MOTOR-DR1VEN AIR COMPRESSOR plete operative demonstration. Apparatus throughout thelength of 150 ft. down the main aisle of the building is suppliedwith compressed air from large central reservoirs or with elec-tric current from the Westinghouse exhibit plant in the Palaceof Machinery, and attendants are ready to illustrate the effi-ciency of each separate device under conditions of actual prac-tice, many important working parts being shown also in sec-tion. It is interesting as evidence of the great progress achievedin the application of power brakes in street railway service inthe past three years, since the Pan-American Exposition atBuffalo, that about one-half of the entire exhibit space is de-voted to the products of the Westinghouse Traction BrakeCompany. The display includes a Bemis electric truck of adouble-truck car. equipped with the Westinghouse magneticbrake, operated on a track 50 ft. long; the arrangement of oneside of a wide single truck,
