| Hs.{Lord Ernest Hives - Chair} LID{A. J. Lidsey} CHASSIS AGENDA. x2924 Hyl/R.30.11.33. MINUTES OF CONFERENCE HELD AT DERBY ON THURSDAY, NOVEMBER 30TH 1933. Present: Sg.{Arthur F. Sidgreaves - MD} C. Wor.{Arthur Wormald - General Works Manager} E.{Mr Elliott - Chief Engineer} By.{R.W. Bailey - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Hy.{Tom Haldenby - Plant Engineer} 20/25 H.P. Minute No. 1. Item 1 on Agenda. Engine Gear Rattles. HAl0/MJ.19.9.33. H420/MW27.9.33. Page 4 Minutes under date 22.9.33. HAl8/MW14.11.33. Wor{Arthur Wormald - General Works Manager}8/R.16.11.33. C4/C16.11.33. Sft.{Mr Swift}2/DH.{D. Henderson - Showroom}18.11.33. Sg.{Arthur F. Sidgreaves - MD} enquired when the balancing cam mechanism would be able to be incorporated in production chassis. Wor.{Arthur Wormald - General Works Manager} said that this is scheduled to be introduced on C2 Series commencing February 24th. Wor.{Arthur Wormald - General Works Manager} also expressed the view that we should be able to do something better and introduce the improvement at an earlier date as it is of such vital importance. By.{R.W. Bailey - Chief Engineer} was requested to look into the matter more deeply with a view to introducing this device at a much earlier date than the one specified. 2. Item 2 on Agenda. Slipping Clutches. Hs.{Lord Ernest Hives - Chair} stated that there were two main causes for this trouble, one being the presence of oil on the clutch fabrics, and the other being imperfect splines which on occasion caused sticking and did not slide freely. He stated that the splines could be corrected and made to work freely. With reference to the presence of oil on the fabric E.{Mr Elliott - Chief Engineer} has developed a design primarily for use on the tank engines but which could be applied to the chassis engines. This device is now running on a 10,000 mile test. It consists of a mechanism using a felt gland to prevent oil from getting on to the clutch friction surfaces. 3. Item 3 on Agenda. Spitting in Exhaust. Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}2/KT.28.11.33. E.{Mr Elliott - Chief Engineer} reported that there is no definite cure available for this complaint so long as the present standard RR. carburetter is used and that improvement can only be effected in these cases by skilful adjustment. He pointed out that the new design of RR. straight through expanding carburetter will eliminate this trouble entirely. | ||
