| x+84. To Hs.{Lord Ernest Hives - Chair} from E.{Mr Elliott - Chief Engineer} c. Wor.{Arthur Wormald - General Works Manager} By.{R.W. Bailey - Chief Engineer} GORY re Universal Joints with Needle Bearings. A recent development with regard to transmission systems as we are aware is the introduction of needle roller bearings, and attached herewith is a print of the type of joint that Hardy Spicer are experimenting with incorporating this type of bearing. If you are in agreement we could obtain a set of these joints and run them on a chassis. The advantages we should hope to gain would be: No.1. Saving in weight. No.2. Greater durability. No.3. Lower manufacturing costs. No.4. Less servicing required. Regarding point No.1, this joint should be capable of carrying heavier loads than the plain bearing type. We are asking Hardy Spicer to supply further information showing how this joint compares with the plain bearing type with regard to horse-power transmission. Efficiency does not enter much into the question as we do not run the joints through any constant angle. Regarding point No.3, this joint has not got the somewhat difficult pieces of the Mechanics type we are at present using, and so far as we can see is a very straightforward production job.
