In operation the wheel 12 is rotated to effect type selection, the band being moved by engagement of the notches 19 and lugs 31. However in the event the band is moved so no notch and lug are in engagement then (in Fig. 1) the knurling 20 engages grooves 28 or alternatively (in Fig. 7) the knurling 20 engages the smooth portion 28a of the band to effect a driving connection.</p> |
