base or frame, A, upon which the shaft rests,

so as to show its operation. A driving-wheel, B, is fixed on the solid or stiff part E of the shaft, which solid part is mounted in suitable bearings .l in the frame, as'usnal. A balance or fly wheel, O, is shown as likewise mounted or the solid or stiil' part of the shaft Band- 'llCC-lS :1) are also shown as mounted on the solid portions of the shaft.
