The wheel can be adjusted to close at any desired wind-pressure by- 

 means of a sliding weight upon the arm of the small vane. It may 

 be turned by hand edgewise to the wind by a chain passing to the 

 ground. The working parts of another vane-governor mill of ex- 

 cellent design are shown in Fig. 1. A portion of the wind- wheel is 

 represented at L L, the rudder- vane at M, and the small governor-vane 

 at N. This latter is in a plane parallel with the face of the wheel, at 

 a slight distance back of it, and extends beyond its edge. The wheel 

 is supported upon an iron frame, 1, which turns within the tubing 17 

 and the additional bearing 18. The wheel-shaft passes through the

bearing 2 and gives motion to the pump-rod by a crank, 10, as shown. 

 To one side of the frame 1 a weighted lever is pivoted, which termi- 

 nates in a toothed segment. This gears with a curved rack on the frame 

 of the rudder-vane, so that, moving the lever upward, the rudder and 

 wheel approach each other. The chain 35 passing over the pulley 20
