52.255. Rotating Crank and Slot, Figure, changes uniform rotation into unsymmetrical, 

 periodic rotation 



The axes of the crank and slot are placed so close to each other that the slot .rotates. 



52.256. Crank and Slot, the slot arranged to rotate, Figure 



This gear is similar to the previous one; the axes of the crank and slot are, however, placed 

 at such a distance apart that the slot can no longer rotate but only oscillate. 



52.257. Equal-limb Rotating Crank and Slot 



52.258. Oscillating Cross Slot, for versed sine motion, Figure 



52.259. Rotating Cross Slot, Figure 



52.260. Oldham's Coupling, Figure, serving as organ of transmission between two parallel 

 axes 



A practical application of the rotating cross slot. The two axes have the same angular velocity.
