RE BRAKE GEAR - GOSHAWK. ------------------------- With reference to your M/C10-2-20 we had done some work on this brake gear last September but had to put it on one side in favour of more urgent work, until the 20 Horse revived a few weeks ago, when we have done a little more on it. We are now proceeding to lay out this brake gear with the differential countershafts behind the cross member opposite the front end of the rear springs, as you instruct, and hope to send you the scheme in the course of a short while. In the meanwhile in view of the previous work we have done, and in case it may be of interest, I am sending prints of the schemes we had done so far. None of these schemes are finished, and we should probably want to alter the details in a good many cases before we thought them satisfactory, but we shall not now do any more work on them. "N" Scheme 212 shews the lay-out of the pedals and brake gear - quarter-size, to shew the way it fits in the chassis. In this scheme the brake differential shafts are made concentric and come in front of the torque sphere, and it was found that there was one position here where one appeared to be able to get down the clutch and uncouple the transmission without interfering with the brake shafts. A support is provided for the brake rods on the cross member (Contd). | ||
