To all whom it may concern: steam, I surround one of the radiating-pipes Be it known that I, IVILLIAM C. BAKER, of with a jacket H in the form of a tube, there the city and State of New York,have invented being a steam-space between the outside of an Improvement in Railway-Car Heaters, of the tube containing the circulating water and which the following is a specification. the inside of the surrounding tube containing The object of this invention is to convert steam, and there are branch pipes 7 and 8, the Baker or any other hot-water heating leading up from the steam-supply tube I to apparatus made use of in railway-cars into a this jacket,near the ends thereof. This jacket heater in which steam from the locomotiveis shown around one of the radiating-pipes IO boiler or other source is made use of. In the adjacent to the lower end of the coil in the Baker car-heater there is a fire-chamber with fire-chamber, in order that the heat imparted a coil which becomes heated by the fuel and to water or brine may cause it to circulate the heated Water rises into an expansion-vesupwardly through the coil in the heater to the sol and then descends and flows through the expansion-vessel and thence back through I 5 radiating-pipes within the car and returns to the radiators in the car.
