THE ADVANTAGES OF 



of doing more work per day at less cost than any other. Land 

 can be ploughed by it at one-half the cost of horse-power.

 Steam Ploughing Engine. These engines are made of 6, 10, 

 .14, and 20 horse-power. They are constructed with single

steam-jacketed cylinders, and are provided with steam domes. 

 The road-gear is constructed of spur-wheels, and made 

 entirely of the best crucible steel. The road-wheels are 

 wrought iron, from 16 to 24 inches wide. The engine has 

 two travelling speeds, and is available as a traction-engine, 

 and can be used for any agricultural purpose, such as 

 threshing, pumping, grinding, sawing, or any operation of 

 the kind. The power is conveyed to the winding drum by 

 an upright shaft from the crank shaft. The winding appa- 

 ratus consists of a horizontal drum, which, by means of coil- 

 ing gear, winds and unwinds the wire rope uniformly without 

 any attention from the man in charge. This is done by a 

 self-acting lever, which carries two vertical guide pulleys, 

 moving slowly up and down, and freely swinging round the 

 drum into any position at which the rope has to work. By 

 this means all strain on the rope, as well as on the apparatus, 

 is avoided.
