steam chest pressure. The crank case is an aluminium casting and contains the entire moving parts of the engine. except the piston and valves. The diff ferential is also contained in the crank case and the taper tubes of the axle bolt directly to it, which makes the en- zine and axle one unit. The main bear ings and the big end connecting rod bearings are annular roller and are of such proportions that no wear should occur during the natural life of the car
 HARDENED STEEL
 All the other bearings, such as the wrist pins and valve gear bearings are hardened steel, running in hardenede steel bushings. Due to the slow speed of the engine (geared one to one with the axie) and to the steel berings, no forced feed-feed -oiling system-is necessary, and IS the casing is oil tight the oil is kept comparatively cool, and no carbon, water or gasoline can con- taminate the oil. The power is trans mitted to the rear axle by means of two spur gears, a forty seven tooth gear on the engine crank shaft and forty tooth gear on the differen- tial. There are no chain-speed gears, and no clutch. and the engine has more power than is needed to spin the wheels
 
 pumps which keep the boiler supplied are bolted on to the right side of the crank case and are driven by a roller bearing crank on the end of the engine crank shaft. In the delivery pipe there Is a pass valve operated by means of a thermostatic tube, which passes the water back to the tank when the water level in the boiler is above normal
 LIGHTING SYSTEM
 The electric system, to take care of the lights, horn and combustion system, comprises a dynamo and a storage battery. The dynamo IS located on the rear of the crank case and is driven from the main axle drive gear After the steam has done it's work in the en- zine it is led to the top of the radiator. and in passing down through the pas sages gives it heat up to the air pass ing through the radiator and condenses into water. The water of condensation returns to the water tank where 1t en- ters near the bottom, so that at nearly all times the opening is below the sur face of the water. The car will travel approximately 5000 miles on one gallon of lubricating oil, due to the entire lack of destructive temperatures and to the fact that the oil is saved along with the water from the exhaust of the en- zine. KEROSENE USED
 The fuel used is kerosene only. No gasoline is used for starting It is stored in a tank at the rear of the chassis and is made to flow into the venturi tube by small rotary pump, which is directly connected to the blowers The power plant consists essentially of the l steam generating apparatus and the 1 engine, or steam using apparatus. The 1 generator is of the water tube type consisting primarily of a number of identical sections placed in an insulated i easing.
 The combustion takes place in com- 1 bustion chamber of efficient design made of special refractory material, | which attains a very high temperature and insures perfect combustion bv l heating the gases before they burn, | and by its very effective catalyptic l action.
 FUEL SYSTEM
 The gases rise past the tubes of the | eVaporator portion, and are then passed 1 over bridge wall and down past the l tubes Of the economiA-r portion, where ! the remaining heat units are abstract 1 ed by the relative cool water entering | the generator by way of the economizer !
 The fuel is burned by means of | system that entirely eliminates any | attention or labor on the part of the i drlVer, and reduces the time necessary ! to start the car from cold by the 1 amount formerly necessary to properly 1 pre-heat the vaporiZer. Thus the air | is made to pass through device which { mixes into it q correct amount of fuel. then this mixture Is led into the com 1 bustion chamber, where it is ignited by i means of an electric spark plug. To ! cause the air to flow there is a small | blower. driven by an electric motor such as Is used in vacuum cleaners, and l this blower forces air through the car ouretor into the combustion chamber. All that is necessary in order to start | and run the car is to turn the switch ! to the running position, open the throttle and the car starts off.
