TRUCK SAFETY ATTACHMENT An attachment the function of which is to set the airbrakes automatically whenever the car or tender truckto which it is attached is derailed or becomes broken, hasbeen placed in successful operation on several railroads bythe Wright Safety Air Brake Company, Greensboro, It consists of a valve, attached to the body of thecar or tender, connected to the brake pipe underneath. A from Tram Line. Section of Valve for Truck Safety Attachment section of this valve is shown in one of the accompanyingillustrations. It is operated by the pin A which is in di-rect line with the center bearings of the car and extendsthrough an adjustable collar located on the track. As thepin A is moved in any direction by this collar it rocksthe disc to which the pin is attached, forcing the valve Bfrom its seat and allowing air from the brake pipe to pass
