ENGINE LUBRICATION.

IMPORTANCE OF GEAR 'BOX

Much attention has been given to the matter of engine lubrication, and rightly so. But it would seem that the gear-box, although it does not have to work under such extreme temperatures as is the case with the engine, should hate a good deal of attention paid to it in this matter of lubrication. Generally, gear-box lubrication consists of filling the gear-box at infrequent intervals, and trusting to its permeating the essential mechanical details of that device. But if one considei s the great pressures winch have to be transmitted by the gear teeth anil the shaft hearings, it seems that this promiscuous kind of lubrication could well be improved upon. It would be essentially sound engineering to provide pump lubrication lor gears' and their shafts and hearings. It would add to the life of the gear and promote silence, because it would ensure oil film between the surfaces. It would make gear changing easy, because the sliding wheels would move easily on their castellated shafts, and the selector bar being supplied similarly with oil under pressure would work more smoothly and easily, anil gear changing might be made a most smooth and easy operation. It rnaj be that the time will come when the advisability of a really well-designed automatic lubricating system for the gear-box will be considered as important a feature of car design as is the elaborate and fool-proof automatic and positive force lubrication ol the engine which we find on the majority of good cars to-day.
