| Hs.{Lord Ernest Hives - Chair} from E.{Mr Elliott - Chief Engineer} c. to CJ. COPY ORIGINAL B4 E1/M4.4.22. GOSHAWK 11. RE LUBRICATION OF LOW TENSION MAKE AND BREAK. We note your complaints regarding the wear of the make and break and we have asked Derby to try first of all the simplest device we can think of as shewn in sketch. OIL This consists of a number of vertical holes drilled from the underside of the cam and filled with absorbent cotton or felt plugs. Small radial holes lead from the plugs on to the flats of the cam. What we hope is that the wicks will pick up and absorb oil from the puddle that is formed above the ball bearing by putting a charge of oil into the external lubricator. When the wicks are soaked with oil it is hoped that some of it will gradually feed out on the surface of the cam by centrifugal force and suction due to the cam revolving. There are many ways by which we can convey oil up to the desired point but unless we use wicks or felt plugs the supply may be sudden instead of gradual. It is probable that with or without lubrication, fibre will prove superior to Bakelite Duck. E.{Mr Elliott - Chief Engineer} | ||
