also the quantity and propor- 

 tion of water in accordance 

 with the needs of the engine. 

 The valve plate in 

 the Secor carburetor is 

 provided with one or 

 more mathematically 

 proportioned air pas- 

 sages and is connected with the 

 governor in such a manner 

 that it is absolutely positive in its workings. In this manner an 

 unfailing link is established between the operation of the engine, 

 its loads, and the fuel supply and every variation of the belt and 

 draw bar pull instantaneously makes itself felt in the fuel mixture 

 and the next explosion is proportioned to meet the new need. This 

 is a vital element in the Secor principle. 



The Secor principle of combustion which is followed out in 

 oTj^Mf is adapted for use in automobiles, railway locomotives, 

 truck wagons, motor street cars, stationary engines of all designs, 

 as well as marine engines. 



Our governor is simple and at the same time extremely sensi- 

 tive. It operates on the throttling principle, by which greater 

 uniformity can be secured, and the vibration and shock of the 

 irregular and violent explosions of the "hit and miss" engine 



avoided. The governor is posi- 

 tively actuated by gears and is 

 enclosed in a dust and water 

 proof case. Thus it is pro- 

 tected from injury, and 

 the gear transmission 

 avoids the danger and 

 annoyance of belt 

 slippage and the con- 

 sequent irregularity. 

 The close speed 

 regulation of the pi/^f 

 governor is unequaled 

 by any other engine. The 

 speed can be adjusted 

 while the engine is in opera- 

 tion. The practicable speed 

 range is three times greater 

 than heretofore achieved, since
