52.361. Epicycloidal Gear with Bevel Wheels, Figure, for demonstrating the simultaneous * ' 

 rotation of a sphere about two intersecting axes j 7. 10. o 



The model shows the simultaneous rotation of a sphere, about two intersecting axes, also, the 

 fact that this rotation is equivalent to the rolling of a cone on a fixed cone. The sphere in tins 

 system of wheels rotates about a momentary axis which is continually altering its position with refe- 

 rence to the sphere.
