| Mcr J.{Mr Johnson W.M.} for R.{Sir Henry Royce} RE RADIATOR TEST. R9/IB24315. 20 HP 25.3.15. M1/G25315. I am enclosing a blue H.11490 shewing in detail, the bracket we were proposing to use on above test. This is the bracket we use on Renault Test and the one we have ordered for the 200 HP test, which we suggested to you could be used for this Radiator Test. The reason the propeller is mounted on a tube is to allow the coupling for engine and dynamometer to pass through it. The pulley is a Richards split steel pulley, and is similar to one in use on Renault Test. We did not employ swivel bearings because we thought it necessary to have a ball thrust and did not know how to swivel it, cheaply. We therefore provided levelling screws in foot of brackets, as being an easy way of aligning them, and also of getting them the same height as engine and dynamometer (necessary, because of the starting clutch) All the parts are new, except brackets supporting radiator. | ||
