| Hs.{Lord Ernest Hives - Chair} X292. BENTLEY. NOTES OF CONFERENCE AT DERBY ON MONDAY, OCTOBER 23rd 1933 RE BENTLEY CHASSIS. PRESENT:- Wor.{Arthur Wormald - General Works Manager} E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Hy.{Tom Haldenby - Plant Engineer} My. Wor.{Arthur Wormald - General Works Manager} said he had called the Conference to try to clear up the Bentley position so as to enable the standardisation sheet to be signed up and allow production to proceed. Minute No. 1. Engine Revs. In view of the opinion expressed by Hs.{Lord Ernest Hives - Chair} that customers will exceed 4,500 revs. Wor.{Arthur Wormald - General Works Manager} said it was obvious that we have nothing to standardise which is safe to run at over 4500 revs. and definite proof by 10,000 miles test is still required that what we have is safe for standardisation for use up to 4,500 revs. 2. Pistons. E.{Mr Elliott - Chief Engineer} exhibited a broken piston and Con Rod from the car which had run in France. The broken piston is one which has been heat treated and the pistons which are fitted to the first 15 chassis now being used for trial runs were not heat treated but simply had the low temperature treatment. While it was not considered that the heat treatment could have anything but a beneficial effect on the condition of the material it was decided for the time being to use pistons of similar treatment to those in the 15 cars, i.e. with low temperature treatment only. Hs.{Lord Ernest Hives - Chair} suggested that we may find it advisable to adopt the higher gear ratio so as to make it less likely for the revs. to exceed 4,500. This was discussed and it was considered to have much to recommend it but no decision was made and the subject was left open for further discussion. 3. Propeller Shaft Joints. Hs.{Lord Ernest Hives - Chair} said that all the Universal joints used in France had shown signs of seizure except the needle bearing joint now under test and it would appear that the needle bearing type of joint will be recommended for standardisation very soon. | ||
