To find the Form of a Tooth which shall gear correctly with one ichose Form is given.—If a toothof any reasonable form be given to a wheel, it is possible to find the curves which by rolling uponthe pitch-circle shall generate the given tooth-outline; and, by using the same describing curves inconnection with the pitch-circle of another wheel, to construct a tooth which will work correctly withthe first one. The describing curve may or may not be a circle; but the operation above describedis more laborious, and the result less reliable, than the mechanical method illustrated in Fig. the form of the assigne
