might have been constituted of two gyrostatic 

 members, but four are shown for symmetry. 



the frame which bears it. Each of the hooked rods in Fig. 45 is 

 connected to the framework through a swivel joint, so that the 

 whole gyrostatic framework may be rotated about the axis of the 

 hooked rods in order to annul the moment of momentum of the 

 framework about this axis due to rotation of the fly-wheels in the 

 gyrostats.
