Driving Wheel Brake Location. We have a letter from a correspondentin which he justly criticises the brakecylinder location on some locomotiveswhich is decidedly objectionable, inas-much that such faulty location prohibitsthe ordinary inspection and Ratltva^ i toeumurtc* EnjiHeering END VIEW OK TRIPLE VALVE TESTINGDEVICE. and is likely to cause serious troubleby the failure of these cylinders to dotheir share of the work. The prime complaint is of the locatingof the brake cylinders in a horizontalposition between the frames, immediatelyback of the cylinder saddle. This hori-zontal position is not as desirable as thevertical position, inasmuch that theleather packing rubs on the bottom ofthe cylinder, due to gravity, and therebytends to wear away the bottom portionof the leather. The vertical positionwould correct this and permit the pack-ing to -wear evenly on all sides of thecylinder. Perhaps the greatest objection is thatthe packing leathers are subjected to asgreat heat from the steam passingthrough the cylinder saddles as theywould be were the cylinders in their oldposition on the frames at the side of thefire-box.
