349,595. Heating vehicles. HILES J. E., Offa Street, St. Peter's Square, Hereford. Feb. 20, 1930, Nos. 5619 and 34710. [Classes 64 (i), 64 (ii), and 123 (ii).] A motor vehicle is heated by hot water or steam circulated from a water heater through which the exhaust gases pass, and which is secured against the cylinder block of the engine. A water chamber 3, Fig. 2, is provided with upper and lower compartments 4, 5, connected by tubes 6. A damper 14 in the compartment 5 is adapted, in the position shown, to divert exhaust gases from the cylinder block 1 upward through the tubes 6 and thence into the exhaust conduit 13a. When the damper 14 is raised to the dotted position, the water heater is cut out and the exhaust gases are discharged direct. The damper 14 may be in any intermediate position. The water chamber may be filled to the top of the tubes 6, and the steam generated passes through an external tube 7 to a superposed chamber 2, and thence through pipe 8 to a suitable radiator. Water may be used in place of steam as the heating medium, in which case the chamber 2 is filled with water or dispensed with. In a modification, Fig. 6, the exhaust gases from the passage 10 pass over hollow baffles 20 communicating with the water chamber 3. The first Provisional Specification describes a water heater or steam generator which takes the place of the cylinder head water jacket, and is provided with controlling valves to connect it either to the cooling system or to the heating radiator in the vehicle. To facilitate generation of steam, the cylinder head jacket may have parts depending into the combustion space.
