GEARING AND GEAR MOTION, ETC. 239 623. VARIABLE SPEED FRICTION GEAR. The disks on theshaft B are permanently fastened in position by blind screws, and the flanges C, C grip two other disksD, D, the latter having springsbetween them to force themapart and insure a good fric-tional contact with the disksC, C. The curves are circulararcs with different radii for thetwo sets of disks, and the de-sign is so worked out that it isbut necessary to move the two shafts together or asunder the distanceE, about f inch, to obtain the entire range of the speed 624. VARIABLE SPEED GEAR. In the engraving the shaft,driven direct or through back gears from the pulleys, is shown at a. This shaft carries at & a long c is a nest of spur gears securedon the shaft d, through which themachine mechanism is will be noticed in thisbank in the revolving gear box. ^^mm
