| To Co. from Bn.{W.O. Bentley / Mr Barrington} C.R. G.Rn.{Mr Robinson} C. EH. Mr. Dy.{F R Danby} X.3456 X3565 Bn{W.O. Bentley / Mr Barrington}5/P28.5.19. RE STANDARDIZATION SHEET - X.3456. CAPILLARY TUBE THERMOMETER With reference to your blue pencilled note on attached memorandum Bn{W.O. Bentley / Mr Barrington}16/P22.5.19 and your remarks on the standardization sheet, I feel that in my note I did not make as good a case for the fitting of the capillary thermometer without the shutters as it deserves. -- I did not appreciate that there was much liklihood of the external shutters being stopped. I pointed out that the thermometer alone will enable the driver to drive the car a little more wisely than without, but I should expand this statement as follows :- With the thermometer fitted the driver will be accurately informed at all times as to whether the engine is running under fair and normal conditions of temperature, and will therefore not be alarmed or annoyed if he experiences piston knocks, popping in carburetter, and general lack of power when he observes that the water temperature is too cold. Without the thermometer he will probably experience annoyance, and will be too ready to believe that the engine is quite hot enough and ought not to misbehave in this way. The thermometer will also render easier, the work of our inspectors when investigating a customer's complaints. The difference in the behaviour of the engine when normally hot compared with being too cold is remarkable. Contd. W.R. 5327 (300 D) (E'ton 400 30-1-19) D'by Street. | ||
