The need of layingthe dust is doubtless generally appreciated so far as more faresis concerned; but the economy of operating over a dustlessroad, as regards truck and motor wear and non-arcing of cur-rent by keeping the wheels and rails in contact, is probably notso often considered. The friction which follows the entranceof dust into even the most carefully guarded motor bearings The Lunkenheimer Company, of Cincinnati, has just broughtout a mechanical oil cup for cylinder lubrication, which itrecommends as more reliable than lubricators hydrostaticallyoperated. When properly constructed the company believesthat with mechancial lubricators all of the oil fed to the pumpis bound to be forced to the steam chest or cylinder of theengine. As will be seen the driving mechanism is of the ratchet type,and is operated by two clutches, that work co-operatively by. SPRINKLING CAR WITH SUCTION PUMP and axle-boxes heats the revolving parts, and not infrequentlyresults in permanent injury. Arcing of the current, caused bydust and sand on the track, is a waste of power, and may evencause serious injury to generators, motors or even controllers. The sprinkler shown in the illustration is one of several ofthis type, built by the J. G. Brill Company, of novel feature in connection with it is an electrically-operated centrifugal filling pump, located under the car at thecenter. The purpose of the pump is to fill the tank from astream or pond through a hose having a foot-valve. Thismakes the sprinkler independent of hydrants and the heavy taxusually imposed for their use, or saves the expense of elevatedtanks and pumping outfits. The Bergen Turnpike Company, of Hoboken, N. J., hasordered two of these cars, with 4000-gal. tanks, capable ofsprinkling 6 miles to 8 miles of roadway, according to speedand charac
