HI-SPEED NEEDLE BALL BEARING HANDPIECE No. 'I0 WITH WHAT IT IS: The Midwest TRANS-SPEED is an efficient speed multiplier, mounted on the .',CI I0 Hi-Speed Handpiece delivering hlgher usable speed than previously obtained by any other means. HOW IT WORKS: Speed is multiplied at the hand- piece by the mechanical ratio of a small idler, driven by the cord, and transmitting energy at high speed to the handpiece spindle alone. TRANSMISSION FUR HIGH SPEED HIINDPIECES increases hcmdpiece speed at the spindle . . . with no speed increase in idler pulleys on engine arm WHY IT WORKS Higher speed is delivered to the cutting surface because energy is conserved in o slow moving belt and pulley system, result- in in an increase in rotational energy at the spindle.
