| To EFC. from E.{Mr Elliott - Chief Engineer} Copy to CJ. " " BN.{W.O. Bentley / Mr Barrington} " " EH. " " DA.{Bernard Day - Chassis Design} " " BY.{R.W. Bailey - Chief Engineer} ORIGINAL. X.3034 - MAIN SWITCH. RECEIVED In reply to your memo EFC1/T5/9/19, paragraph 3, the word "stamping" in our paragraph 3 should have read "standard", thus - "The boss on the inside" of the brush standard should be definitely cut back clear of the brush so as to ensure that the brush blades shall always be free and not scraping or touching on the boss." With the help of the sketch below I think this will now be clear. E.{Mr Elliott - Chief Engineer} BRUSH BOSS FOR TERMINAL CONNECTION TO STANDARD. | ||
