The twowheels being in gear, it is obvious that as the beam A rises andfalls, the second wheel with the assistance of the fly, will re-volve quite round the first, and if the number of teeth beequal, the first, or sun wheel, must perform two rotations on itsaxis, while the second, or planet wheel revolves once round it.

As the wheel revolves,the bar E F will move up and down, once dur-ing each revolution. This reciprocal motionmay be indefinitely varied by bending the edgeof the wheel into different curves and an-gles. Epicycloidal Wheel.—A verybeautiful method of convertingcircular into alternate motionor alternate into circular, isshown in Fig. 33. A B is afixed ring, or wheel, toothed onits inner side. C is a toothedwheel of half the diameter ofthe ring, revolving about thecentre of the ring. While. Fig. 33.
