October 21, 1911.] ELECTRIC RAILWAY JOURNAL 9^3 IMPROVED TRUCK BRAKE RIGGING Martin A. Pahler, formerly master mechanic of theConnecticut Company at New Britain, Conn., recently hasbeen granted a patent on an improved form of truck brakerigging which has been applied to a number of cars inNew Britain. The principal advantages claimed for thisimprovement are simplicity and economy of constructionand maintenance and a higher brake leverage. As will be against the transoms. When the hand brakes are appliedthe pull is toward the ends of the car and the live leversremain stationary. The hand brakes and the air brakesmay be applied independently or simultaneously. FUNICULAR ELECTRIC RAILWAY UNDER CONSTRUCTIONNEAR DENVER. Improved Truck Brake Rigging seen from the accompanying engravings, which show therigging applied to a Brill No. 27-E truck, the brake shoesare inside-hung and the live levers are moved by a topbrake beam at the center of which is attached the. brake-rod passing over the motor frame toward the center of thecar body. The brake shoe hangers are attached to bracketsbolted to the inside faces of the truck side frames. Thesehanger brackets have elongated bolt holes so that theirposition may be adjusted to give any desired angularity tothe hangers. No release springs are used; the shoes fallaway from the wheels of their own weight when the brakesare released. The live levers are bent inwardly to clear thehanger brackets and the two brake levers on each of thetransoms are connected at their bottom ends by the rods toprevent the brake shoes from moving laterally across theface of the wheels. Since the point of attachment of thebrake rod is closer to the center of
