R. 0., New York city, asks:Which is the best kind of a driverbrake, one which has a horizontal pullor one which pulls straight up anddown? A.—A push brake is better thana pull, as the stuffing box is done awaywith. The brake which pushes down ina perpendicular direction is much prefer-able to the horizontal type, for the rea-son that the wear of the packing leather Fitj. a.

The brakes can be operated, if desired,by either the automatic or this straightair feature, independent of each other, orboth can be worked at the same the automatic brakes fail to work,the straight air feature can be operated, position shown in Fig 3, it is on lap,and, as shown in Fig. 4, it will allow thepressure in the pipe to escape, whichrelieves the retainer, causing an auto-matic action of same and allowing thebrakes to release. For switch engines, the device, asshown in Fig. 7, can be used withoutthe aid of the triple, auxiliaries andbrake valves, thus receiving a pressuredirect from the main reservoirs, and re- is even on all sides, and
