TRANSMISSION GEAR for automobiles. The three inter-mediate gears are pinioned to aseparate plate from the outsidegear, and controlled by a brakestrap. There being two compart-ments and two sets of gear, thebrake strap on each compart-ment controls the speed and thereverse motion. 621. Left hand set of gears. 622. Right hand set of gears. 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 variation.
