CENTRAL LUBRICATION. The average results of the central lubrication scheme in the hands of the customers is very good, but there are one or two faults which need attention. We have been reviewing the whole scheme so that we can take advantage of any improvements on any new cars such as J.3 or 'Peregrine'. The present drip plugs we use, we buy from Messrs. Luvax, and as they have to be made specially for R.R., they are expensive. The present soldered Banjo fittings we use are not satisfactory. Most of the troubles we have in service are due to the failure of the soldered joint and therefore we consider it advisable for us to get some experience with the connections as recommended by Bijur because from our experience they make a better oil tight joint, are cheaper, and much more accessible. We have therefore arranged with Messrs. Luvax to alter one of our 25 HP. cars, using their standard fittings wherever possible and using their type of connections. We also gave them a free hand as regards the run of the pipe lines and they are using their standard coil arrangement to get from the frame to the axle, this they claim has given entire satisfaction with thousands of cars in service. Their pump has one advantage over ours and that is, if it is operated when the tank is empty of oil it does not force air into the pipe lines. The car they have altered for us is very good for uniform pressure throughout the system. We get a pressure of 100 lbs. at all points. What we are hoping to achieve is less cost, greater reliability, and improved accessibility. We are obtaining the difference in price, and shall be able to send this on later.
