GOLD INSIDE CONNECTED VAPORVALVE III the application of the vapor heating to passengercars the jiractice has been to place the vapor regulatingvalve underneath the car. To overcome the oljjections arisingfrom the inaccessibility of this location and the Section Through the Valve Body jKJSure to which the valve is subjected, the Gold Car Heating& Lighting Company has placed on the market an insideconnected vapor valve which is designated as No. 1112. The construction and operation of the valve is simple andmay readily be grasped from an inspection of the sectionalview. At the right are the branch pipe and radiator admis-sion connections, the steam passing from the fomier to the J (^ % 1 ^ ■ G 0 L D 5 m ^ PATENTe^M ^ Gold No. 1112 Inside Connected Vapor Valve latter through the diaphragm controlled admission valve operation of the admission valve is controlled by anexpansion diaphragm of a design which provides sufficientflexibility to obviate the necessity of the use of an adjustingscrew within the range of the working pressure encountered inpassenger train heating practice. The movement of thediaphragm is transmitted to the valve by a single straight stemwhich is normally held i
