Hardy - Chief Dev. Engineer}6/ET. Sunday, 6th October, 1940. Dear Mr. Hardy, As mentioned during my recent telephone conversation I must apologize for not replying to your letter earlier, and trust this will not have caused you any trouble. We have in the past made quite a variety of clutch throwout bearings, both similar to the New Departure and other weird shapes in order to meet with certain existing conditions, but of course the present national position makes it difficult if not impossible to consider any production of such bearings, and even when we come back to normal times the question will still arise as to whether such bearings will be worth while, but this naturally will depend upon the advantages obtained from every view point. I am enclosing assembly drawings of a number of the bearings, which are typical of those we have made, and I might add that we have also made similar bearings with the extended face on the inner instead of on the outer. The construction on all is very similar, with the exception of the one shown on B.10386 which is a construction which can use an entirely standard bearing, the loose side plates providing the necessary face for the clutch fingers, and the pressed casing not only provides the oil retention on the one side but also effects the retention of the side plate on the other side, and it seems to me that perhaps some design of this type would be the most acceptable to yourselves. With regard to our 4/LJT.50, I happened to have one of these tucked away amongst some of my samples, and Contd/ [Stamp: Enclosure] Branch Offices: - Belfast — Birmingham — Bristol — Dublin — Glasgow — Leeds — Manchester — Newcastle — Nottingham — Sheffield | ||
