. Railway mechanical engineer . thatthe center of the bearing was 22 in. above the floor bushings were placed in the bearings and babbitted tosuit the 6-in shaft which was turned out of an old axle. Onone end the shaft carries the saw, which is made from j4-in. 359 360 RAILWAY MECHANICAL ENGINEER Vol. 90, No. 7 boiler plate, and a 16-in. belt pulley is placed on the otherend. The shaft runs at a speed of 2,800 r. p. m. Two baseplates are bolted to the foundation to form the runway forthe rail carriage, which is pulled into and out of the sawby means of a 10-in. air brake cylinder bolted on the floor atthe rear of machine. These base plates are from the toolcarriages of the scrapped wheel lathe. The two carriageswhich have been built to run on the base plates each havetwo 4-in. air cylinders bolted on the under side, the pistonsof which are connected to levers which clamp the rail on thecarriages. The angle at which the rail is cut is adjusted bychanging the relative position of the two carriages. This is. A Rail Saw Built from an Old Wheel Lathe done by adjusting the length of the connecting bar from thebrake cylinder to one of the carriages. The rail-clamp topplates are then turned and locked at the desired angle. Whenin operation the saw is cooled by a stream of water, the pipeentering the hood over the saw as shown in the actual cutting time with this machine is less than 30seconds for one 85-lb. rail. The operator stands about fivefeet away from saw by the two four-way cocks at the left ofthe photograph. One cock controls the rail clamps and theother the feed in and out of the saw.
