S.H. 885A (100 T) (S.H 798, 10-12-89) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 8947 X.2894. Contd. Proposed Alterations to American RR Car -6- By December, 2nd. 1919. The suggestion, we presume, is to raise the radiator bodily, not increase its area, which appears ample at present. (20) In the steering box there is a special aluminium block T2417 on the single fixing bolt. This has been often found to break while in use in the car, and we are substituting bronze blocks on repair work here. We would suggest this as standard, or else the use of a machined steel nut. (21) { They want entirely re-desinging and modernising; they are out of date. The angle brackets supporting the (front floorboards might be simplified, we think, by simply welding bosses on them to take the cheese head screws fixing the floorboards. At present a seperate cast bronze boss is bolted to each angle bracket. (22) Tank suspension. The diagonal stay -- Supporting the petrol tank is fastened to the frame at its forward end by a stamped plate which also formed a part of the old radiator suspension. It is thought that this plate might be dispensed with and the diagonal stay fastened by a single taper bolt direct to the frame. (23) Spanners. All of the spanners supplied with the chassis are considerably thinner than the nuts which they fit, with the single exception of the 2.B.A. The smaller sized could well be increased in thickness, since they are rather weak. The 1/4" jaw which is made part of the 2 B.A. spanner is particularly weak. (24) X.186 X.2894 Repair of platinum points by brazing thin discs of platinum on the old contacts has been practised for some time at the service station, with complete success, and much saving in platinum. We would draw this practice to the attention of England, and also the practice of brazing tungsten discs to an iron tack, for the same purposed. The brazing of the platinum is recommended and the tungsten contacts suggested for experiment. This would apply, on new cars, only to the battery contact breaker. (25) The magneto for American cars remains to be decided. We have sent samples of the Berling & Splitdorf. Other makes will be investigated and samples, sent, if found interesting. Contd. | ||
