Dear Sir:- Re: Alemite Lubricators. We notice from the Reports of Experimental Work that it is proposed to fit Alemite Lubricators on "Goshawk II". We would recommend that before definitely deciding on the Alemite system you should inspect the Rimtco system, parts of which were sent with 4-EX. This we believe to be a distinct improvement on the Alemite, because it is more easily attached and disconnected. Both of the systems, however, tend to leak a good deal at the nozzle when used with oil, although they are perfectly satisfactory with grease. The great disadvantage of the Alemite system is that when used with a straight screwed nipple, it is very easy to unscrew the nipple when attempting to disengage the bayonet joint. We have now got some samples of better schemes than either of these. In fact, the situation with respect to this type of lubricator is developing so fast that better and better types are being evolved every month. The more recent types, generally speaking, do not use a hose on the gun but arrange for direct application of the gun by using cranked elbows, etc. to make each lubricator accessible. The Alemite system has even recommended dropping the hose. Several schemes are being evolved which are specially designed for oil, and we hope shortly to be able to send you a really good example of an oil lubricator scheme which we think you will consider much superior to the Alemite. The details of application are practically the same for the Alemite as for the other schemes, so that it scarcely affects | ||
