Wor{Arthur Wormald - General Works Manager}/Hy{Tom Haldenby - Plant Engineer} Hand Adj. for F.{Mr Friese} brakes on new car. 22-9-13 on flow to 2300. No trouble yet. A lot of small compass. great skill needed in Presly to ensure free & smooth working. X2 DUNLOP DET. WIRE WHEELS. pt set adapted 22-9-13 to D.R. Brakes 'Lighter drums' - Springing out of round Poor brakes. foul'g of oil cover at top & thicker ones CK.{Mr Clark} Wt diff - 3 lb 6 oz per wheel. DRB now being produced. ? was heavy drums & interim Crs to delete pull off. Aqueduct to delete stiff. 30-9-13. V.{VIENNA} lighter section. (15-10-13) X2 Wor{Arthur Wormald - General Works Manager}/Hy{Tom Haldenby - Plant Engineer} c J.R. By.{R.W. Bailey - Chief Engineer} Ns.{Norman Scott} DRB tested & car stops 11-10-13. "070" play for a few days. 10 hrs usage OK 15-10-13. CJ to Wss 2700 car quite unsuitable for use in trafic 13-11-13. The Balloon goes up! Brake poor at slow speed. OK at 5mph. It makes tests. Wor{Arthur Wormald - General Works Manager} sends info. X2 Wor{Arthur Wormald - General Works Manager}/Hy{Tom Haldenby - Plant Engineer} - I am sorry ref ↑ Oily or wet? No front brakes 18-11-13. drums springing? Mont press. needed then old. CJ car central for violent retardation. DRB and old 29-11-13. CJ to Wor{Arthur Wormald - General Works Manager} effective & much sweeter. Tests Hy{Tom Haldenby - Plant Engineer} old DFBO old control (at 5mph). If J can NBG If any doubt it is in favour of DRB got to combine him & this. CJ to Wor.{Arthur Wormald - General Works Manager} Noise - DRB & old? Compare was change over 21-12-13. mobile Hand & enter? who is to tackle R.{Sir Henry Royce} apart noise & got to conquer. Exp to be tackled (a b. silly suggestion). DRB. Two R's. R to Da{Bernard Day - Chassis Design} Ref brake alter. complication not formed. No. V 16-12-13. Simpler with Da{Bernard Day - Chassis Design}'n a Drop. CJ.Wor{Arthur Wormald - General Works Manager} X2 Worthy. J says we must exp. to be sure now. 17-12-13. we must try to find out a.{Mr Adams} R to By.{R.W. Bailey - Chief Engineer} c Wor{Arthur Wormald - General Works Manager} & J.{Mr Johnson W.M.} Ref London info - Dist getting muddy? 18-12-13. making noisy? Al. cones affected? roughly water flung in all direction and across their. X2 J for R(?) Covers already turned on. Lining Linings n Fabrege cp? 24-12-13. on London Showroom. J.{Mr Johnson W.M.} R to By "C" Wor.{Arthur Wormald - General Works Manager} Oil mplf on - quicker than 3-1-14. I'm sure that this was put on. R - loaned for Hy{Tom Haldenby - Plant Engineer} that this was 27-1-14. did not report it. - We learn this by accident - 25-4-14. A singler Hs.{Lord Ernest Hives - Chair} Wor{Arthur Wormald - General Works Manager}/Mer for Hy.{Tom Haldenby - Plant Engineer} Tests on 7 or 1 samples @ Shffl 27-4-14. new shoes diff. Exp after 600 miles. - 1500 miles. Little diff Retu good or bad ??? PN{Mr Northey} to J & Wor.{Arthur Wormald - General Works Manager} Latest DRB - Worries & disappears 27-4-14 to RR Std. Not consistent. FB now effective & quiet & inefficient (& miles silent by paraffin inf/n). DRB reports after eg mackquick can be oiled & it cleared. DRB My (PN{Mr Northey}) Linings in past ?? rapid wear. eg mackbuick new shoes - 2,000 miles. 27-4-14. after 700m! Open Trials car, 2,000 mi. expectation - 10,000 mi. ??? Wor{Arthur Wormald - General Works Manager}/Mer not sent to J ?? Hy{Tom Haldenby - Plant Engineer} queries what car wrong 28-4-14. Exp to lastes 10,000. Has sup? Ns{Norman Scott} inch samples. & tests are being made & long or short lifers. Wor{Arthur Wormald - General Works Manager}/Mer not sent to J.{Mr Johnson W.M.} Not trial 99% load as 28-4-14. margin note). Bronze - good for silent OK for wear. test Linings copper being tried. Wor{Arthur Wormald - General Works Manager} 4 page report to J.{Mr Johnson W.M.} ref 'Conference'. 28-4-14. may be Pd. By.{R.W. Bailey - Chief Engineer} Hy.{Tom Haldenby - Plant Engineer} H's ref noisy FB. 1) Noisy rapid wear. may come from 2) New supplies? closed metal 3) Ref Crs report - in Churchward. bronze. better than C1. Exp - on silent. Squeak supply. Full C. danger Club repeats to be tried on. Marginalia (Left side, in red ink): Wor{Arthur Wormald - General Works Manager} to By del'g.{Mr Griffiths - Chief Accountant / Mr Gnapp} Spring. By puts facts to Hy{Tom Haldenby - Plant Engineer} - 704. Matched with R+ ang. car and adjustment. when over hauled. CJ Wor{Arthur Wormald - General Works Manager} They were in action increased the water. J to By.{R.W. Bailey - Chief Engineer} ref brakes. Peuguot says they are powerful, silent & almost frictionless. J to Wor{Arthur Wormald - General Works Manager} Reports on brake noise. Victory initial. Not to be 12 months maintenance. to be known to them mentioning names. J to Wor{Arthur Wormald - General Works Manager} to fix brake system. Ref letter to RB.{R. Bowen} Don't want adjustment. Positive lock. He also says thin lining worked well. 23-4-14 Replied to my previous note 27-4-14 efficient. who can say who designed them? Ref to R.{Sir Henry Royce} after init. Sit on him. Ref Cr{Mr Cra???ster / Mr Chichester}: Churchward. The question of this Design is difficult on who practiced X. By difficult on fact.
