| - 6 - releasing the clutch pedal is now :- 1. Disengage main clutch. 2. Apply band brake. 3. Release band brake. 4. Engage main clutch. the reverse clutch being permanently held out which is what is required for free wheel operation. On changing back to fixed or for reversing, the Bowden control is first operated which tends to pull the plunger 2. to the left. As the extension 6. has engaged with the annular groove 7. on the plunger 2. the latter is for the time being locked and the operation of the Bowden control merely compresses the spring 3. without moving the plunger. The clutch pedal is then depressed which moves the projection 6. of the operating fork clear of the recess 7. in the plunger 2. and the latter being now free is forced to the left by the comparatively strong spring 3. which overcomes the resistance of the lighter spring 5. The object of this delayed action being to prevent the possibility of the reverse clutch being engaged except when the main clutch is free. On releasing the clutch pedal the operating fork R.{Sir Henry Royce} is free to move fully back, the reverse clutch engages, and the sequence of operations for fixed drive is re-established. The adjustment of the band brake is carried out by rotating the operating spindle V.{VIENNA} by means of a screwdriver through the cap securing the spring X, the spindle being prevented from rotating accidentally by a spring loaded detent Z. The action of rotating the spindle raises or lowers the die block to which the free end of the brake band is secured, thus decreasing or increasing the brake clearance, and the adjustment should | ||
