Union Engines Give Longer 



Service Than Any Other 



Engines in the World 



Hundreds of UNION engines over twenty years old are 

 still giving faithful service every day. 



These are not idle statements, they are facts that are sub- 

 stantiated by thousands of UNION owners and operators. 



Consider the reasons for this remarkable service: 



Design 



UNION engines are carefully designed by engineers who 

 built the first marine gas engine ever constructed in the world. 

 The parts of our engines are proportioned to give maximum 

 wearing service without unnecessary weight. 



Inlet Manifold 



For the use of gasoline as fuel any manifold will give fair 

 results, but the proper use of distillate demands a heated in- 

 take pipe that will prevent liquid fuel entering the cylinders. 

 The UNION patented exhaust heated inlet manifold has 

 produced the only distillate engine that is practically as flexi- 

 ble as a steam engine. 



Reverse Gear 



One of the chief things to be considered in the purchase of 

 a marine gas engine is the reverse gear. UNION engines 

 are equipped with a spur gear reverse that is positively the 

 strongest and most efficient reverse gear on any engine today. 

 It has been successfully constructed to transmit 600 H. P., 

 and has proved that in the matter of repairs and upkeep it is 

 far ahead of the former bevel gear type of reverse. 



Thrust Bearings 



We have adopted the recommendations of the leading 

 thrust bearing manufacturers in the world, and as a result, 

 all three cylinder UNION engines of medium power are 

 equipped with roller thrust bearings. Our experience has 

 demonstrated that this type of bearing is the best for taking 

 up the powerful thrust of a heavy duyt engine. UNION 

 open crosshead engines are equipped with hollow, water- 

 cooled thrust blocks, designed in accordance with established 

 marine steam engine practice. 



Economy 



The remarkable economy of UNION engines has been 

 established beyond the question of a doubt by the perform- 

 ance of engines equipped with our exhaust heated inlet mani- 

 fold. This device prevents any unburnt fuel passing through 

 the engine, and insures maximum power with minimum fuel 

 consumption — more power delivered to the propellor, less 

 power wasted in the exhaust. Do not take our word for 

 these statements; ask any UNION owner about his fuel 

 bill, or write to us for copies of unsolicited letters.
