A Fireless Locomotive 



rp, 



It is run on live steam secured from the power plant on the fac- 

 tory site and stored in the engine tank until gradually exhausted 



^HE locomotive illustrat- 

 I ed consists of a large, 

 round-ended tank with 

 a false end at the front and 

 fitted with only such appa- 

 ratus as is required for the 

 control of the steam to the 

 cylinders. The latter, all the 

 driving mechanism and the 

 outside lagging to prevent 

 heat radiation are exactly like 

 those of an ordinar>' loco- 

 motive. 



Three crosswise perforated 

 baffle plates are fitted in the 

 tank. These serve to prevent 

 the water from surging from 

 one end to the other and to 

 prevent the locomotive from 

 rocking. 



In operation, the tank is 

 first filled about half full of 

 water. This enters through 

 a valve at the front and 

 passes into and out of a long 

 perforated pipe extending the 

 full length of the tank near 

 the bottom. Then live steam 

 from the power plant on the 

 factory site is admitted to the 

 tank through the same pipe as was the 

 water. By the time the pressure be- 

 tween the boiler and the tank is equalized, 

 generally at one hundred and fifty pounds, 

 the water level in the tank will be raised 

 considerably and the temperature of the 

 water will be nearly equal to that of the 

 steam by which it is charged, about three 



For freight-car switching service in and around industrial plants 

 and factories, the fireless locomotive meets an urgent need

THROTTLE VALVE 



The fireless locomotive has no boiler and no means of provid- 

 ing fire. Outwardly, however, it resembles the steam engine 



hundred and seventy degrees Fahrenheit. 

 The steam is then drawn off through a 

 throttle-valve in a dome in the tank top 

 and led through a pipe to a reducing-v^alve 

 in the false front end of the tank. This 

 valve reduces the pressure of the steam to 

 between sixty and sixty-five pounds per 

 square inch before it is led to the cylinders. 

 These are especially large in 

 diameter so that the piston 

 area is such that the locomo- 

 tive can be moved when the 

 steam is at a pressure of four 

 pounds. The exhaust steam 

 is carried out through a pipe 

 in the stack as shown. 



As the steam is used, the 

 pressure in the tank becomes 

 less and less, allowing the 

 water to evaporate gradually 

 and maintain a steam supply 

 until it has been depleted to 

 the point where it is no longer 

 sufficientlv effective.
