Note.—The depth sunk in the shaft and in the wheel is measured at the side of the key, and not at its centre. The breadth of the key is equal from end to end, but the thickness must be regulated to give auniform taper for the purpose of fitting tightly in its place. The amount of taper should be about 2511. 2508, 2509. one-eighth inch to a foot in length, and the same must be given to the key-seat in the boss of thewheel, and not to the key-bed in the shaft. Fig. 2511 illustrates the method of keying a wheel to a square shaft. It is used for shafts that 214 KIBBLES. 2513. 2514. B UlJ n. \i
